Abstinent
Kinds of Abstinent Terms modified by Abstinent Selected AbstractsChanges in the Episodic Memory and Executive Functions of Abstinent and Relapsed Alcoholics Over a 6-Month PeriodALCOHOLISM, Issue 3 2009Anne Lise Pitel Background:, It is still unclear whether episodic memory and executive functions capacities can return to normal in abstinent patients over a 6-month period. Furthermore, the role of interim drinking in cognitive recovery is still not well known. Finally, further research is required to specify the predictive value of cognitive abilities at initial testing in the treatment outcome (abstinence or relapse). The aims of the present study were therefore to measure changes in episodic memory and executive functions over a 6-month period in abstinent and relapsed alcoholics and to ascertain whether neuropsychological results at treatment entry can predict treatment outcome at follow-up. Methods:, Fifty-four alcoholic patients and 54 matched control subjects performed baseline neuropsychological tasks assessing episodic memory, executive functions, the slave systems of working memory and attentional abilities. At the follow-up session (i.e., 6 months later), episodic memory and 3 executive functions (inhibition, flexibility, and updating) were re-examined in the alcoholic patients. Results:, Results showed that over the 6-month interval, the abstainers' episodic memory and executive performances had returned to normal, whereas the relapsers performed lower than before in the flexibility task. Episodic memory and executive functions recovery was correlated, in abstainers, with drinking history and age respectively. Finally, there was no significant difference regarding neuropsychological scores at baseline between abstainers and relapsers. Discussion:, Over the 6-month interval, abstainers normalized episodic memory and executive performances whereas relapsers obtained executive results which were more severely impaired, emphasizing the influence of interim drinking on cognitive changes. Episodic memory, executive functions, the slave systems of working memory and attentional abilities did not appear to be reliable predictors of treatment outcome over a 6-month interval. [source] Levels of ,-Aminobutyric Acid-Benzodiazepine Receptors in Abstinent, Alcohol-Dependent Women: Preliminary Findings From an 123I-Iomazenil Single Photon Emission Tomography StudyALCOHOLISM, Issue 9 2000A. R. Lingford-Hughes Background: Although alcohol dependence in women is an increasing problem, little is known about the effects of alcohol on the female brain. Evidence from a few structural and functional neuroimaging studies suggests that the female brain may be more susceptible than the male brain to the harmful effects of alcohol. However, no in vivo studies of the neuropharmacology of alcohol dependence in women have been carried out. The aim of this preliminary study was to test the hypothesis that alcohol dependence in women is associated with greater reduction in ,-aminobutyric acid (GABA)-benzodiazepine receptor levels than in men with an equivalent drinking history. Methods: We used single photon emission tomography and 123I-iomazenil to label the central GABA-benzodiazepine receptor and to compare semiquantified levels in 9 abstinent alcohol-dependent and 13 control women. These groups were further compared with equivalent male groups from a previous study. Results: There was a trend toward a reduction in GABA-benzodiazepine receptor levels in alcohol-dependent women, but this did not reach significance. These lower levels were seen primarily in the cerebellum, occipital lobes, and parietal cortex (left > right). This was in marked contrast with the pattern of reduction seen in the previous study of male dependence, where significant reductions were seen primarily in the frontal cortex. Conclusions: Due to the semiquantitative analysis performed and the relatively small number of subjects in this study, which resulted in a nonsignificant trend, we can only comment on the differences in the pattern of lower levels of GABA-benzodiazepine receptors seen in alcohol dependence in men and women. Although we are not able to ascertain whether the female brain is more susceptible to the effects of alcohol, it appears that alcohol has a differential effect on the central GABA-benzodiazepine receptors in men and women. Recent animal evidence supports this hypothesis. Future studies should explore whether other neuropharmacological differences exist between men and women in alcohol dependence that could have implications for pharmacotherapy. [source] Drinking goal selection and treatment outcome in out-patients with mild-moderate alcohol dependenceDRUG AND ALCOHOL REVIEW, Issue 4 2001SIMON J. ADAMSON Abstract Selection of drinking goal is examined at baseline, post-treatment and at 6 months follow-up for a sample of mild-moderate alcohol-dependent out-patients. Drinking goal is identified as abstinent or controlled drinking, with the latter group being asked to further specify per session and per week drinking limits. Group comparisons for drinking goal post-treatment show those who were not assigned motivational enhancement therapy, had more drinking days and lower scores on the Alcohol Problems Questionnaire and Internal Motivation were more likely to choose controlled drinking. The only variable to predict independently whether or not the controlled drinking goal was within the promoted drinking guidelines was age, with younger participants more likely to choose a goal above this limit. Goal selection was significantly related to drinking outcome, with those aiming to drink within guidelines having better outcome than those aiming for higher limits. There was no significant difference in drinking outcome category when those aiming for within limits were compared to those aiming for abstinence. Clinical implications of these findings are discussed. [source] Challenges to antagonist blockade during sustained-release naltrexone treatmentADDICTION, Issue 9 2010Nikolaj Kunøe ABSTRACT Aims Naltrexone is a competitive opioid antagonist that effectively blocks the action of heroin and other opioid agonists. Sustained-release naltrexone formulations are now available that provide long-acting opioid blockade. This study investigates the use of heroin and other opioids among opioid-dependent patients receiving treatment with long-acting naltrexone implants, their subjective experience of drug ,high' after opioid use, and factors associated with opioid use. Methods Participants (n = 60) were opioid-dependent patients receiving treatment with naltrexone implants. Outcome data on substance use, drug ,high', depression and criminal activity were collected over a 6-month period. Blood samples were taken to monitor naltrexone plasma levels, and hair samples to verify self-reported opioid use. Findings More than half [n = 34 or 56%; 95% confidence interval (CI) 44,68%)] the patients challenged the blockade with illicit opioids during the 6-month treatment period; 44% (n = 26; 95% CI 32,56%) were abstinent from opioids. Mean opioid use was reduced from 18 [standard deviation (SD)13] days during the month preceding treatment to 6 days (SD 11) after 6 months. Of the respondents questioned on opioid ,high' (n = 31), nine patients (30%; 95% CI 16,47%) reported partial drug ,high' following illicit opioid use, and three (12%; 95% CI 3,26%) reported full ,high'. Opioid use was associated with use of non-opioid drugs and criminal behaviour. Conclusions Challenging naltrexone blockade with heroin on at least one occasion is common among sustained-release naltrexone patients, but only a minority of patients use opioids regularly. Challenges represent a warning sign for poor outcomes and often occur in the context of polydrug use and social adjustment problems. [source] Failure to improve cigarette smoking abstinence with transdermal selegiline + cognitive behavior therapyADDICTION, Issue 9 2010Joel D. Killen ABSTRACT Aims To examine the effectiveness of transdermal selegiline for producing cigarette smoking abstinence. Design Adult smokers were randomly assigned to receive selegiline transdermal system (STS) or placebo given for 8 weeks. All participants received cognitive behavior therapy (CBT). Follow-ups were conducted at 25 and 52 weeks. Setting Community smoking cessation clinic. Participants 243 adult smokers (,18 years of age; ,10 cigarettes/day). Measures Expired-air carbon monoxide confirmed 7-day point prevalence abstinence. Findings STS was not superior to placebo. More women than men were abstinent at 52 week follow-up (28% vs 16%, P < 0.05). Behavioral activation (BAS) moderated treatment response (P = 0.01). The survival rate through week 52 for those with high ,drive' scores on the BAS was 47% if assigned to selegiline and 34% if assigned to placebo. The survival rate for those with low ,drive scores' on the BAS was 35% if assigned to selegiline compared to 53% if assigned to placebo. Conclusion Transdermal selegiline does not appear generally effective in aiding smoking cessation though there may be a selective effect in those smokers with low ,behavioral activation'. [source] Individuals receiving addiction treatment: are medical costs of their family members reduced?ADDICTION, Issue 7 2010Constance Weisner ABSTRACT Aims To examine whether alcohol and other drug (AOD) treatment is related to reduced medical costs of family members. Design Using the administrative databases of a private, integrated health plan, we matched AOD treatment patients with health plan members without AOD disorders on age, gender and utilization, identifying family members of each group. Setting Kaiser Permanente Northern California. Participants Family members of abstinent and non-abstinent AOD treatment patients and control family members. Measurements We measured abstinence at 1 year post-intake and examined health care costs per member-month of family members of AOD patients and of controls through 5 years. We used generalized estimating equation methods to examine differences in average medical cost per member-month for each year, between family members of abstinent and non-abstinent AOD patients and controls. We used multilevel models to examine 4-year cost trajectories, controlling for pre-intake cost, age, gender and family size. Results AOD patients' family members had significantly higher costs and more psychiatric and medical conditions than controls in the pre-treatment year. At 2,5 years, each year family members of AOD patients abstinent at 1 year had similar average per member-month medical costs to controls (e.g. difference at year 5 = $2.63; P > 0.82), whereas costs for family members of non-abstinent patients were higher (e.g. difference at year 5 = $35.59; P = 0.06). Family members of AOD patients not abstinent at 1 year, had a trajectory of increasing medical cost (slope = $10.32; P = 0.03) relative to controls. Conclusions Successful AOD treatment is related to medical cost reductions for family members, which may be considered a proxy for their improved health. [source] A brief alcohol intervention for hazardously drinking incarcerated womenADDICTION, Issue 3 2010Michael D. Stein ABSTRACT Objective To test the hypothesis that among hazardously drinking incarcerated women who are returning to the community, a brief alcohol intervention will result in less alcohol use at follow-up relative to standard of care. Methods Eligible participants endorsed hazardous alcohol consumption,four or more drinks at a time on at least 3 separate days in the previous 3 months or a score of 8 or above on the Alcohol Use Disorders Identification Test. Participants were randomized to either an assessment-only condition or to two brief motivationally focused sessions, the first delivered during incarceration, the second 1 month later after community re-entry. Participants recalled drinking behaviors at 3 and 6 months after the baseline interview using a 90-day time-line follow-back method. Results The 245 female participants averaged 34 years of age, and were 71% Caucasian. The mean percentage of alcohol use days in the 3 months prior to incarceration was 51.7% and heavy alcohol use days was 43.9%. Intervention effects on abstinent days were statistically significant at 3 months (odds ratio = 1.96, 95% confidence interval 1.17, 3.30); the percentage of days abstinent was 68% for those randomized to intervention and 57% for controls. At 6 months the effect of the intervention was attenuated and no longer statistically significant. Conclusions Among incarcerated women who reported hazardous drinking, a two-session brief alcohol intervention increased abstinent days at 3 months, but this effect decayed by 6 months. Study participants continued to drink heavily after return to the community. More intensive intervention pre-release and after re-entry may benefit hazardously drinking incarcerated women. [source] Ethnic differences in drinking outcomes following a brief alcohol intervention in the trauma care settingADDICTION, Issue 1 2010Craig A. Field ABSTRACT Background Evidence suggests that brief interventions in the trauma care setting reduce drinking, subsequent injury and driving under the influence (DUI) arrest. However, evidence on the effectiveness of these interventions in ethnic minority groups is lacking. The current study evaluates the efficacy of brief intervention among whites, blacks and Hispanics in the United States. Methods We conducted a two-group parallel randomized trial comparing brief motivational intervention (BMI) and treatment as usual with assessment (TAU+) to evaluate treatment differences in drinking patterns by ethnicity. Patients were recruited from a level 1 urban trauma center over a 2-year period. The study included 1493 trauma patients, including 668 whites, 288 blacks and 537 Hispanics. Hierarchical linear modeling was used to evaluate ethnic differences in drinking outcomes including volume per week, maximum amount consumed in 1 day, percentage days abstinent and percentage days heavy drinking at 6- and 12-month follow-up. Analyses controlled for age, gender, employment status, marital status, prior alcohol treatment, type of injury and injury severity. Special emphasis was given to potential ethnic differences by testing the interaction between ethnicity and BMI. Results At 6- and 12-month follow-up, BMI significantly reduced maximum amount consumed in 1 day (P < 0.001; P < 0.001, respectively) and percentage days heavy drinking (P < 0.05; P < 0.05, respectively) among Hispanics. Hispanics in the BMI group also reduced average volume per week at 12-month follow-up (,2 = 6.8, df = 1, P < 0.01). In addition, Hispanics in TAU+ reduced maximum amount consumed at 6- and 12-month follow-up (P < 0.001; P < 0.001) and volume per week at 12-month follow-up (P < 0.001). Whites and blacks in both BMI and TAU+ reduced volume per week and percentage days heavy drinking at 12-month follow-up (P < 0.001; P < 0.01, respectively) and decreased maximum amount at 6- (P < 0.001) and 12-month follow-up (P < 0.001). All three ethnic groups In both BMI and TAU+ reduced volume per week at 6-month follow-up (P < 0.001) and percentage days abstinent at 6- (P < 0.001) and 12-month follow-up (P < 0.001). Conclusions All three ethnic groups evidenced reductions in drinking at 6- and 12-month follow-up independent of treatment assignment. Among Hispanics, BMI reduced alcohol intake significantly as measured by average volume per week, percentage days heavy drinking and maximum amount consumed in 1 day. [source] Consequences of chronic ketamine self-administration upon neurocognitive function and psychological wellbeing: a 1-year longitudinal studyADDICTION, Issue 1 2010Celia J. A. Morgan ABSTRACT Background ,Recreational' use of ketamine is spreading rapidly among young people. In healthy individuals an acute dose of the N-methyl D-aspartate (NMDA) receptor antagonist ketamine induces marked psychosis-like effects and cognitive impairments, but little is known about the long-term effects of the drug. Aims To evaluate the long-term neuropsychiatric or cognitive consequences. Methods A total of 150 individuals were assessed, 30 in each of five groups: frequent ketamine users, infrequent ketamine users, abstinent users, polydrug controls and non-users of illicit drugs. Twelve months later, 80% of these individuals were re-tested. Results Cognitive deficits were mainly observed only in frequent users. In this group, increasing ketamine use over the year was correlated with decreasing performance on spatial working memory and pattern recognition memory tasks. Assessments of psychological wellbeing showed greater dissociative symptoms in frequent users and a dose,response effect on delusional symptoms, with frequent users scoring higher than infrequent, abstinent users and non-users, respectively. Both frequent and abstinent using groups showed increased depression scores over the 12 months. Conclusions These findings imply that heavy use of ketamine is harmful to aspects of both cognitive function and psychological wellbeing. Health education campaigns need to raise awareness among young people and clinicians about these negative consequences of ketamine use. [source] Individualized assessment and treatment program for alcohol dependence: results of an initial study to train coping skillsADDICTION, Issue 11 2009Mark D. Litt ABSTRACT Aims Cognitive,behavioral treatments (CBT) are among the most popular interventions offered for alcohol and other substance use disorders, but it is not clear how they achieve their effects. CBT is purported to exert its beneficial effects by altering coping skills, but data supporting coping changes as the mechanism of action are mixed. The purpose of this pilot study was to test a treatment in which coping skills were trained in a highly individualized way, allowing us to determine if such training would result in an effective treatment. Design Participants were assigned randomly to a comprehensive packaged CBT program (PCBT), or to an individualized assessment and treatment program (IATP). The IATP program employed experience sampling via cellphone to assess coping skills prior to treatment, and provided therapists with a detailed understanding of patients' coping strengths and deficits. Setting Out-patient treatment. Participants A total of 110 alcohol-dependent men and women. Measurements Participants in both conditions completed experience sampling of situations, drinking and coping efforts prior to, and following, 12 weeks of treatment. Time-line follow-back procedures were also used to record drinking at baseline and post-treatment. Findings IATP yielded higher proportion of days abstinent (PDA) at post-treatment (P < 0.05) than did PCBT, and equivalent heavy drinking days. IATP also elicited more momentary coping responses and less drinking in high-risk situations, as recorded by experience sampling at post-treatment. Post-treatment coping response rates were associated with decreases in drinking. Conclusions The IATP approach was more successful than PCBT at training adaptive coping responses for use in situations presenting a high risk for drinking. The highly individualized IATP approach may prove to be an effective treatment strategy for alcohol-dependent patients. [source] Varenicline in prevention of relapse to smoking: effect of quit pattern on response to extended treatmentADDICTION, Issue 9 2009Peter Hajek ABSTRACT Aim While older behavioural and pharmacological approaches to preventing relapse to smoking show little efficacy, a recent randomized trial of an extended course of varenicline reported positive results. In this secondary analysis, trial data were examined to see whether smokers who manage to achieve abstinence only later in the original course of treatment are more likely to benefit from having the course extended. Methods A total of 1208 patients abstinent for at least the last week of 12 weeks' treatment with varenicline were randomized to 3 months continued varenicline or placebo. Overall, 44% of the 12-week abstainers were abstinent from the target quit date (TQD), while the rest stopped smoking later. We examined the relationship between quit pattern and the varenicline versus placebo difference in continuous abstinence rates at week 52 and contributions of baseline patient characteristics. Results With increasing delay in initial quitting, 12-month success rates declined. Participants who had their last cigarette at week 11 of open-label treatment had quit rates at 52 weeks of 5.7% compared with 54.9% in those who last smoked in week 1 [odds ratio (OR) 20.3 (6.3, 65.9); P < 0.0001]. Patients who failed to initiate abstinence in the first week benefited more from extended treatment than patients continuously abstinent from week 1 [OR 1.7 (1.2, 2.4); P = 0.0015 versus OR 1.1 (0.8, 1.5); P = 0.6995, respectively; with the interaction of the quit pattern with treatment effect reaching borderline significance (P = 0.0494)]. No other patient characteristics were related to treatment effect. Conclusions Compared with smokers who quit smoking on their TQD, those who have an initial delay in achieving sustained abstinence have increased risk of relapse even several months later, and may be more likely to benefit from extended treatment with varenicline. [source] Progressive stage transition does mean getting better: a further test of the Transtheoretical Model in recovery from alcohol problemsADDICTION, Issue 6 2009Nick Heather ABSTRACT Aims To test two central assumptions of the Transtheoretical Model (TTM) regarding recovery from alcohol problems: (i) individuals making a forward transition from pre-action to action stages will show greater drinking improvements than those remaining in pre-action stages; and (ii) individuals remaining in pre-action stages will not demonstrate improvements in drinking outcomes. Design and setting Large, multi-centre, randomized controlled trial of treatment for alcohol problems [United Kingdom Alcohol Treatment Trial (UKATT)]. Measurements Stage of change, drinks per drinking day and percentage days abstinent at baseline, 3- and 12-month follow-ups. Findings In support of TTM assumption 1, improvements in drinking outcomes were consistently greater among clients who showed a forward stage transition (Cohen's d = 0.68) than among those who did not (d = 0.10). Two tests of assumption 2 showed a significant improvement in drinking outcomes in non-transition groups, inconsistent with the TTM; one test showed a significant deterioration and the other showed equivalent drinking outcomes across time. An explanation is offered as to why, under the relevant assumption of the TTM, clients in non-transition groups showed small changes in drinking outcomes. Conclusions In contrast to a previous study by Callaghan and colleagues, our findings largely support the TTM account of recovery from alcohol problems in treatment. The discrepancy can be explained by the use in our study of a more reliable and valid method for assigning stage of change. [source] Facilitating involvement in Alcoholics Anonymous during out-patient treatment: a randomized clinical trialADDICTION, Issue 3 2009Kimberly S. Walitzer ABSTRACT Aim This study evaluated two strategies to facilitate involvement in Alcoholics Anonymous (AA),a 12-Step-based directive approach and a motivational enhancement approach,during skills-focused individual treatment. Design Randomized controlled trial with assessments at baseline, end of treatment and 3, 6, 9 and 12 months after treatment. Participants, setting and intervention A total of 169 alcoholic out-patients (57 women) assigned randomly to one of three conditions: a directive approach to facilitating AA, a motivational enhancement approach to facilitating AA or treatment as usual, with no special emphasis on AA. Measurements Self-report of AA meeting attendance and involvement, alcohol consumption (percentage of days abstinent, percentage of days heavy drinking) and negative alcohol consequences. Findings Participants exposed to the 12-Step directive condition for facilitating AA involvement reported more AA meeting attendance, more evidence of active involvement in AA and a higher percentage of days abstinent relative to participants in the treatment-as-usual comparison group. Evidence also suggested that the effect of the directive strategy on abstinent days was mediated partially through AA involvement. The motivational enhancement approach to facilitating AA had no effect on outcome measures. Conclusions These results suggest that treatment providers can use a 12-Step-based directive approach to effectively facilitate involvement in AA and thereby improve client outcome. [source] Attendance at Narcotics Anonymous and Alcoholics Anonymous meetings, frequency of attendance and substance use outcomes after residential treatment for drug dependence: a 5-year follow-up studyADDICTION, Issue 1 2008Michael Gossop ABSTRACT Aims This study investigates the relationship between frequency of attendance at Narcotics Anonymous and Alcoholics Anonymous (NA/AA) meetings and substance use outcomes after residential treatment of drug dependence. It was predicted that post-treatment NA/AA attendance would be related to improved substance use outcomes. Methods Using a longitudinal, prospective cohort design, interviews were conducted with drug-dependent clients (n = 142) at intake to residential treatment, and at 1 year, 2 years and 4,5 years follow-up. Data were collected by structured interviews. All follow-up interviews were carried out by independent professional interviewers. Findings Abstinence from opiates was increased throughout the 5-year follow-up period compared to pre-treatment levels. Clients who attended NA/AA after treatment were more likely to be abstinent from opiates at follow-up. Abstinence from stimulants increased at follow-up but (except at 1-year follow-up) no additional benefit was found for NA/AA attendance. There was no overall change in alcohol abstinence after treatment but clients who attended NA/AA were more likely to be abstinent from alcohol at all follow-up points. More frequent NA/AA attenders were more likely to be abstinent from opiates and alcohol when compared both to non-attenders and to infrequent (less than weekly) attenders. Conclusions NA/AA can support and supplement residential addiction treatment as an aftercare resource. In view of the generally poor alcohol use outcomes achieved by drug-dependent patients after treatment, the improved alcohol outcomes of NA/AA attenders suggests that the effectiveness of existing treatment services may be improved by initiatives that lead to increased involvement and engagement with such groups. [source] Does progressive stage transition mean getting better?ADDICTION, Issue 10 2007A test of the Transtheoretical Model in alcoholism recovery ABSTRACT Aims To test two central assumptions of stage movement in the Transtheoretical Model (TTM) vis-à-vis alcoholism recovery: (assumption 1) individuals making a forward transition to the action-oriented stages (i.e. preparation/action) will manifest relatively greater drinking improvements than their counterparts remaining in the pre-action stages (i.e. pre-contemplation, contemplation); and (assumption 2) individuals remaining in the pre-action stages across time will not demonstrate clinically relevant improvement in drinking outcomes. Design and setting Secondary data analyses of data from Project MATCH, a large multi-site alcoholism treatment-matching study. Measurements At baseline and 3 months post-treatment, the following variables were measured: stage-of-change (based on the University of Rhode Island Change Assessment measure and the most recent stage assignment algorithm), drinks per drinking day (DDD) and percentage days abstinent (PDA). Findings Six of the eight tests of assumptions 1 and 2 failed to support the basic tenets of the TTM. Our study demonstrated that individuals making a progressive stage transition to the action-oriented stages (i.e. preparation/action) do not necessarily manifest greater improvements in drinking-related behavior than individuals remaining in the pre-action stages (i.e. pre-contemplation, contemplation), and that individuals remaining in the pre-action stages over time actually do manifest statistically significant and clinically important improvements in drinking-related behavior. Conclusions Our findings challenge not only the criterion validity associated with stage movement in the TTM account of alcoholism recovery, but also recent TTM-based substance abuse treatment approaches which systematically promote forward stage transition as a primary clinical goal and marker of therapeutic success. [source] Effects of rapid smoking on post-cessation urges to smokeADDICTION, Issue 3 2007Hayden McRobbie ABSTRACT Context Rapid smoking (RS) is a smoking cessation technique with sufficient indications of promise to warrant further investigation. The main presumed effect of RS is on reducing desire to smoke. Aim To evaluate the effect of a single session of RS immediately prior to quitting smoking on urges to smoke over the first week of abstinence. Design Randomized controlled trial. Setting Specialist smoking cessation clinic (SSCC). Participants A total of 100 smokers attending the quit day session. Intervention Participants in the rapid smoking group underwent a single session of RS immediately prior to quitting smoking. Participants in the control group watched a health promotion video on giving up smoking. Primary outcome measures Ratings of urges to smoke in the first 24 hours and 1 week of abstinence. Findings The RS procedure was well tolerated. It led to significantly lower urges to smoke compared to the control procedure during the first 24 hours (mean rating of 2.6 versus 3.2, P < 0.001) and the first week of abstinence (1.8 versus 2.5, P < 0.01). In patients abstinent for 4 weeks, urges to smoke were low and the difference was no longer significant (1.4 versus 1.8). Conclusion RS has an ,active ingredient' (craving reduction) and its effects on smoking cessation may merit further examination using modern rigorous methodology. [source] Effectiveness of a smoking cessation intervention in older adultsADDICTION, Issue 1 2007Robert J. Tait ABSTRACT Aims To: (a) identify characteristics of older smokers considering cessation of smoking; (b) evaluate a cessation intervention plus access to nicotine replacement therapy (NRT); (c) identify predictors of those who successfully quit; and (d) evaluate the effectiveness of the intervention in those aged , 75 years. Design Self-selection of: (a) a cessation of smoking programme; or (b) ongoing smoking. Setting Teaching hospital, Perth, Western Australia. Participants A larger study recruited smokers and never smokers: from this the 215 community-dwelling smokers (, 5 cigarettes/day) aged , 68 years (171 males) were enrolled. Intervention Brief intervention with telephone support and access to NRT versus no intervention. Measurements (a) Profile of older adults planning to quit smoking compared with continuing smokers; (b) cessation at 6 months defined as 30-day point prevalence validated via expired carbon monoxide; and (c) factors predictive of successful cessation. Findings There were 165 intervention participants. Compared with the 50 continuing smokers, participants in the intervention were younger and had significantly less years of regular smoking, more previous quit attempts and greater nicotine dependence scores. At 6 months, the point prevalence of ex-smokers was 25% (n = 42) with 20% (n = 33) being abstinent throughout the study. No continuing smoker had ceased smoking. Among the intervention group, logistic regression showed that those who used NRT (OR 4.36), were male (OR 3.17), had higher anxiety (OR 1.67) or rejected ,more colds and coughs' as a reason for quitting (OR 2.91) were more likely to be successful quitters. Of those aged , 75 years (n = 77), 25% matched cessation criteria. Conclusions Older smokers can be engaged successfully in a brief intervention plus NRT as aids to cessation of smoking. The intervention was also effective in the older subgroup of participants. Social factors may provide an additional means of motivating older smokers to quit. [source] A randomized controlled trial of a smoking cessation intervention based in community pharmaciesADDICTION, Issue 2 2001T. A. Maguire Aims. To evaluate whether a structured community pharmacy-based smoking cessation programme (the PAS model) would give rise to a higher smoking cessation rate compared with ad hoc advice from pharmacists. Design. A randomized controlled trial comparing a structured intervention with usual care. Setting. One hundred pharmacists working in community pharmacies in N. Ireland and 24 in London took part in the study and were each asked to enroll 12 smokers; 44% of pharmacists who were trained managed to recruit one or more smokers during the recruitment period of approximately 1 year. Participants. A total of 484 smokers were enrolled by the pharmacists and individually randomized into the PAS intervention group ( N = 265) or the control group ( N = 219). Intervention. The PAS intervention involved a structured counselling programme, an information leaflet and a follow-up weekly for the first 4 weeks then monthly as needed. Measurements. The primary outcome measure of this study was self-reported smoking cessation for 12 months with cotinine validation at the 12-month follow-up. Findings. Of smokers in the PAS group, 14.3% (38) were abstinent up to 12 months compared with 2.7% (6) in the control group ( p < 0.001 for the difference). Conclusion. The community pharmacy-based PAS smoking cessation service can be an effective method of helping people stop smoking when delivered by pharmacists willing to adopt this approach. [source] CLINICAL STUDY: Prolactin response to fenfluramine in abstinent, alcohol-dependent patientsADDICTION BIOLOGY, Issue 3-4 2008Richard J. Porter ABSTRACT It has been suggested that serotonin (5HT) function is abnormal in alcoholics even during abstinence. The prolactin response to fenfluramine (PRF) is generally believed to reflect the activity of the 5HT system and has been previously used to investigate 5HT activity in a variety of conditions, including alcoholism. The origin of the cortisol (CORT) response to fenfluramine is less clear. The objectives of this paper are to examine the prolactin (PRL) and CORT response to dl -fenfluramine in a large cohort of males with alcohol dependence who had been abstinent for 3 weeks, and to compare this with an age-matched control group. Ninety-four subjects with a DSM-III-R diagnosis of moderate to severe alcohol dependence who had been abstinent for 3 weeks, and 23 control subjects underwent neuroendocrine challenge with dl -fenfluramine (10 mg per 10 kg body weight). PRL and CORT responses were measured. No significant difference was found in PRF between abstinent, alcoholic patients and controls (F = 2.7, d.f. = 1.115, P = 0.10). CORT response was significantly lower in abstinent alcoholics than in controls (F = 10.0, d.f. = 1.116, P = 0.002). The results suggest no clear difference in 5HT function between abstinent alcoholics and healthy controls. The reduced CORT response in abstinent alcoholics further supports evidence of hypofunction of the adrenocortical system in this group. [source] Visuo-spatial working memory deficits in current and former users of MDMA (,ecstasy')HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 2 2005Michelle Wareing Abstract Verbal working memory and executive deficits have been observed in ecstasy users. The present study sought to establish whether these also extended to visuo-spatial working memory. Thirty-six current ecstasy users, 12 former users (abstinent for at least 6 months) and 31 individuals that had never used ecstasy were tested on a maintenance plus type visuo-spatial working memory task. The task required participants to recall a sequence of specially marked cells in a four-by-four matrix display while at the same time performing a concurrent visual judgement task. Both the current and former user groups registered impairments relative to nonusers. These remained significant following statistical controls for a range of potentially confounding variables including the use of various other drugs during the 3 months prior to testing. Users were unimpaired on a simple spatial span measure suggesting that the deficits observed reflected the executive aspects of the spatial working memory task. Also consistent with executive involvement, statistical controls for measures of verbal working memory performance (computation span) removed half of the ecstasy-related variance in spatial working memory. The possibility that the pattern of results obtained might reflect some general impairment in information processing efficiency is discussed. Copyright © 2005 John Wiley & Sons, Ltd. [source] Comparison of group and individual cognitive-behavioral therapy for patients with bulimia nervosaINTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 3 2003Eunice Chen Abstract Objective The clinical effectiveness of group and individual cognitive-behavioral therapy (CBT) for bulimia nervosa (BN) was compared. Method Sixty BN patients from hospitals and general practitioners in Sydney, Australia, were allocated randomly to group or individual CBT. Forty-four completed treatment (n = 22 in group CBT and n = 22 in individual CBT). Patients were assessed at pretreatment, posttreatment, and at 3 and 6 months follow-up with the Eating Disorder Examination-12 and self-report questionnaires examining weight and shape attitudes (Eating Disorder Inventory-2), social adjustment (Socail Adjustment Scale-Modified), self-esteem (Rosenberg Self-Esteem Scale), and general psychopathology (Symptom Checklist 90R). Results The effects of group and individual CBT were equivalent on most measures. However, a significantly greater proportion of individual CBT patients than group CBT patients were abstinent from bulimic behaviors at posttreatment, but not at follow-up. Discussion This has implications for the delivery of cost-effective and clinically effective treatment for BN. © 2003 by Wiley Periodicals, Inc. Int J Eat Disord 33: 241,254, 2003. [source] Recommendations for Sexuality Education for Early AdolescentsJOURNAL OF OBSTETRIC, GYNECOLOGIC & NEONATAL NURSING, Issue 3 2006Kristin Haglund Objective:, To determine community support and identify appropriate learning methodologies, parameters of delivery, and intervention content. Design:, Qualitative descriptive study in which participants were interviewed in a semistructured format. Data were analyzed thematically. Setting:, An urban pediatric primary care clinic from which youths and parents were recruited. Participants:, Ten youths, 10 parents, and 10 community members. Community members included professional and laypersons who had experience in working with early adolescents or in working with children of any age on sexuality issues. Overall, most participants were female (67%) and African American (67%). Results:, Descriptions of early adolescents' knowledge of sexuality, participants' support for sexuality education for early adolescents, recommendations for education content, and preferred methods for education delivery. Conclusion:, The participants supported comprehensive sexuality education for early adolescents. They believed that it would help youths to be abstinent, would provide some protection from sexual abuse, and would prepare them to practice safer sex in the future. JOGNN, 35, 369-375; 2006.

Greenfield Background:, Relatively few studies have examined gender differences in the effectiveness of specific behavioral or pharmacologic treatment of alcohol dependence. The aim of this study is to assess whether there were gender differences in treatment outcomes for specific behavioral and medication treatments singly or in combination by conducting a secondary analysis of public access data from the national, multisite NIAAA-sponsored COMBINE study. Methods:, The COMBINE study investigated alcohol treatment among 8 groups of patients (378 women, 848 men) who received medical management (MM) with 16 weeks of placebo, naltrexone (100 mg/day), acamprosate (3 g/day), or their combination with or without a specialist-delivered combined behavioral intervention. We examined efficacy measures separately for men and women, followed by an overall analysis that included gender and its interaction with treatment condition in the analyses. These analyses were performed to confirm whether the findings reported in the parent trial were also relevant to women, and to more closely examine secondary outcome variables that were not analyzed previously for gender effects. Results:, Compared to men, women reported a later age of onset of alcohol dependence by approximately 3 years, were significantly less likely to have had previous alcohol treatment, and drank fewer drinks per drinking day. Otherwise, there were no baseline gender differences in drinking measures. Outcome analyses of 2 primary (percent days abstinent and time to first heavy drinking day) and 2 secondary (good clinical response and percent heavy drinking days) drinking measures yielded the same overall pattern in each gender as that observed in the parent COMBINE study report. That is, only the naltrexone by behavioral intervention interaction reached or approached significance in women as well as in men. There was a naltrexone main effect that was significant in both men and women in reduction in alcohol craving scores with naltrexone-treated subjects reporting lower craving than placebo-treated subjects. Conclusions:, This gender-focused analysis found that alcohol-dependent women responded to naltrexone with COMBINE's Medical Management, similar to the alcohol-dependent men, on a wide range of outcome measures. These results suggest that clinicians can feel comfortable prescribing naltrexone for alcohol dependence in both men and women. In this study, it is also notable that fewer women than men reported receiving any alcohol treatment prior to entry into the COMBINE study. Of note, women tend to go to primary health care more frequently than to specialty substance abuse programs for treatment, and so the benefit we confirm for women of the naltrexone and MM combination has practical implications for treating alcohol-dependent women. [source] Mechanisms of Postural Control in Alcoholic Men and Women: Biomechanical Analysis of Musculoskeletal Coordination During Quiet StandingALCOHOLISM, Issue 3 2010Edith V. Sullivan Background:, Excessive sway during quiet standing is a common sequela of chronic alcoholism even with prolonged sobriety. Whether alcoholic men and women who have remained abstinent from alcohol for weeks to months differ from each other in the degree of residual postural instability and biomechanical control mechanisms has not been directly tested. Method:, We used a force platform to characterize center-of-pressure biomechanical features of postural sway, with and without stabilizing conditions from touch, vision, and stance, in 34 alcoholic men, 15 alcoholic women, 22 control men, and 29 control women. Groups were matched in age (49.4 years), general intelligence, socioeconomic status, and handedness. Each alcoholic group was sober for an average of 75 days. Results:, Analysis of postural sway when using all 3 stabilizing conditions versus none revealed diagnosis and sex differences in ability to balance. Alcoholics had significantly longer sway paths, especially in the anterior,posterior direction, than controls when maintaining erect posture without balance aids. With stabilizing conditions the sway paths of all groups shortened significantly, especially those of alcoholic men, who demonstrated a 3.1-fold improvement in sway path difference between the easiest and most challenging conditions; the remaining 3 groups, each showed a ,2.4-fold improvement. Application of a mechanical model to partition sway paths into open-loop and closed-loop postural control systems revealed that the sway paths of the alcoholic men but not alcoholic women were characterized by greater short-term (open-loop) diffusion coefficients without aids, often associated with muscle stiffening response. With stabilizing factors, all 4 groups showed similar long-term (closed loop) postural control. Correlations between cognitive abilities and closed-loop sway indices were more robust in alcoholic men than alcoholic women. Conclusions:, Reduction in sway and closed-loop activity during quiet standing with stabilizing factors shows some differential expression in men and women with histories of alcohol dependence. Nonetheless, enduring deficits in postural instability of both alcoholic men and alcoholic women suggest persisting liability for falling. [source] Parietal Gray Matter Volume Loss Is Related to Spatial Processing Deficits in Long-Term Abstinent Alcoholic MenALCOHOLISM, Issue 10 2009George Fein Background:, We previously demonstrated relatively intact cognitive function (with the exception of suggestive evidence for persistent deficits in spatial information processing) in middle-aged long-term abstinent alcoholics (LTAA, abstinent for 6 months or more) compared to age and gender comparable nonalcoholic controls (NAC) (Fein et al., 2006). Methods:, In the current study, we examine cortical gray matter volumes in the same samples to determine whether gray matter volumes in LTAA are consistent with the cognitive results , i.e., exhibiting gray matter volumes comparable to NAC in most brain regions, except for possible indications of persistent shrinkage in the parietal lobe subserving spatial information processing. Results:, We found gray matter shrinkage in LTAA in the parietal lobe consistent with the spatial processing deficits in this same sample. More compelling, in LTAA, the magnitude of parietal gray matter shrinkage was negatively associated with spatial processing domain performance and positively associated with alcohol dose. Gray matter volume deficits were present in the occipital and other cortical tissue, but poorer visuospatial test performance correlated significantly with smaller volumes in the parietal cortex only. Conclusions:, Taken together, the cognitive and structural imaging data provide compelling evidence that chronic alcohol abuse results in shrinkage of the parietal cortex with associated deficits in spatial information processing. [source] Three-Year Chemical Dependency and Mental Health Treatment Outcomes Among Adolescents: The Role of Continuing CareALCOHOLISM, Issue 8 2009Stacy Sterling Background:, Few studies have examined the effects of treatment factors, including the types of services [chemical dependency (CD), psychiatric, or both], on long-term outcomes among adolescents following CD treatment, and whether receiving continuing care may contribute to better outcomes. This study examines the effect of the index CD and ongoing CD and psychiatric treatment episodes, 12-step participation, and individual characteristics such as CD and mental health (MH) severity and gender, age, and ethnicity, on 3-year CD and MH outcomes. Methods:, Participants were 296 adolescents aged 13 to 18 seeking treatment at 4 CD programs of a nonprofit, managed care, integrated health system. We surveyed participants at intake, 1 year, and 3 years, and examined survey and administrative data, and CD and psychiatric utilization. Results:, At 3 years, 29.7% of the sample reported total abstinence from both alcohol and drugs (excluding tobacco). Compared with girls, boys had only half the odds of being abstinent (OR = 0.46, p = 0.0204). Gender also predicted Externalizing severity at 3 years (coefficients 18.42 vs. 14.77, p < 0.01). CD treatment readmission in the second and third follow-up years was related to abstinence at 3 years (OR = 0.24, p = 0.0066 and OR = 3.33, p = 0.0207, respectively). Abstinence at 1 year predicted abstinence at 3 years (OR = 4.11, p < 0.0001). Those who were abstinent at 1 year also had better MH outcomes (both lower Internalizing and Externalizing scores) than those who were not (11.75 vs. 15.55, p = 0.0012 and 15.13 vs. 18.06, p = 0.0179, respectively). Conclusions:, A CD treatment episode resulting in good 1-year CD outcomes may contribute significantly to both CD and MH outcomes 3 years later. The findings also point to the value of providing a continuing care model of treatment for adolescents. [source] Changes in the Episodic Memory and Executive Functions of Abstinent and Relapsed Alcoholics Over a 6-Month PeriodALCOHOLISM, Issue 3 2009Anne Lise Pitel Background:, It is still unclear whether episodic memory and executive functions capacities can return to normal in abstinent patients over a 6-month period. Furthermore, the role of interim drinking in cognitive recovery is still not well known. Finally, further research is required to specify the predictive value of cognitive abilities at initial testing in the treatment outcome (abstinence or relapse). The aims of the present study were therefore to measure changes in episodic memory and executive functions over a 6-month period in abstinent and relapsed alcoholics and to ascertain whether neuropsychological results at treatment entry can predict treatment outcome at follow-up. Methods:, Fifty-four alcoholic patients and 54 matched control subjects performed baseline neuropsychological tasks assessing episodic memory, executive functions, the slave systems of working memory and attentional abilities. At the follow-up session (i.e., 6 months later), episodic memory and 3 executive functions (inhibition, flexibility, and updating) were re-examined in the alcoholic patients. Results:, Results showed that over the 6-month interval, the abstainers' episodic memory and executive performances had returned to normal, whereas the relapsers performed lower than before in the flexibility task. Episodic memory and executive functions recovery was correlated, in abstainers, with drinking history and age respectively. Finally, there was no significant difference regarding neuropsychological scores at baseline between abstainers and relapsers. Discussion:, Over the 6-month interval, abstainers normalized episodic memory and executive performances whereas relapsers obtained executive results which were more severely impaired, emphasizing the influence of interim drinking on cognitive changes. Episodic memory, executive functions, the slave systems of working memory and attentional abilities did not appear to be reliable predictors of treatment outcome over a 6-month interval. [source] The Association of Sexual Experience with Attitudes, Beliefs, and Risk Behaviors of Inner-City AdolescentsJOURNAL OF RESEARCH ON ADOLESCENCE, Issue 1 2006Ellen Johnson Silver We compared knowledge, attitudes, and demographic characteristics of 630 sexually experienced and 422 inexperienced inner-city adolescents aged 14,17 years. Sexual experience was associated with indicators of risk previously reported in the literature: male gender, older age, single-family home, smoking, drinking, and poorer academic performance. We found lower HIV knowledge in sexually inexperienced youth, which suggested an area of vulnerability compared with sexually active teens. However, most inexperienced adolescents intended to remain virgins for the next 6 months, most had peer groups they also perceived to be virgins, and they were more positive and confident about remaining abstinent. Differences between the groups suggest there may be benefits to developing intervention programs targeted to their different strengths and weaknesses. [source] Factors Affecting %CDT Status at Entry Into a Multisite Clinical Treatment Trial: Experience from the COMBINE StudyALCOHOLISM, Issue 11 2006Raymond F. Anton Background: Carbohydrate-deficient transferrin (CDT) occurs as a higher percentage of normal transferrin (%CDT) in heavy drinkers. %CDT is used as a marker of both alcohol use disorder severity and treatment outcome both clinically and in treatment trials. Nevertheless, little is known about the parameters that predict which patients are %CDT positives at treatment entry. These parameters might include level of drinking, days of abstinence before testing, and severity of alcohol dependence before evaluation. Methods: %CDT levels were collected before randomization from participants of the COMBINE Study, a large federally sponsored multisite clinical trial evaluating medications and behavioral therapies in alcohol-dependent outpatients. %CDT (assayed in a central laboratory) was available in 1,193 individuals for whom drinking history in the 30 days before testing and measures of alcoholism severity were documented. The effects of drinking history and alcohol severity were evaluated for prediction of a %CDT-positive test status. Results: Less percent days abstinent (PDA) and more drinks per drinking day (DDD) were predictive of higher rates of %CDT-positive patients (maximum 67%). Up to 14 days of continuous abstinence before testing did not appear to significantly affect %CDT status. Rates of %CDT positives remained reasonably steady up to about 40% PDA. Years of drinking at dependence levels had an unexpected negative impact on %CDT-positive rates while previous treatment had a small but positive impact of %CDT-positive rates. ADS and DrInC scores had no predictive value over and above recent drinking amounts on %CDT status. Conclusions: %CDT is more likely to be positive in those who have more days of drinking and to a lesser degree in those who drink more per drinking day. It can remain positive even in those alcoholic subjects who stop drinking many days before testing. Alcoholic subjects with more treatment experiences appear to have a marginally higher %CDT-positive rate. [source] Validity of the Alcohol Use Disorders Identification Test in College StudentsALCOHOLISM, Issue 6 2004Patricia K. Kokotailo Background: High-risk alcohol use among college students is associated with accidents, partner violence, unwanted sexual encounters, tobacco use, and performance issues. The identification and treatment of high-risk drinking students is a priority for many college campuses and college health centers. The goal of this study was to test the psychometric properties of the Alcohol Use Disorders Identification Test (AUDIT) in college students. Methods: A convenience sample of students coming into a college health clinic was asked to complete the 10-question AUDIT and then participate in a research interview. The interview focused on assessing students for alcohol abuse and dependence by using the Composite International Diagnostic Interview Substance Abuse Module and timeline follow-back procedures to assess a 28-day drinking history. Results: A total of 302 students met the eligibility criteria and agreed to participate in the study. The sample consisted of 185 females (61%) and 117 males (39%), with a mean age of 20.3 years. Forty students were abstinent, 88 were high-risk drinkers, and 103 met criteria for a 12-month history of dependence. Receiver operator curves demonstrated that the AUDIT had the highest area under the cure for detecting high-risk alcohol use (0.872) and the lowest for identifying persons with a lifetime history of alcohol abuse or dependence (0.775). An AUDIT cutoff score of 6 or greater demonstrated a sensitivity of 91.0% and a specificity of 60.0% in the detection of high-risk drinkers. Conclusions: The AUDIT has reasonable psychometric properties in sample of college students using student health services. This study supports the use of the AUDIT in this population.
