Selected AbstractsInternet-based prevention for alcohol and cannabis use: final results of the Climate Schools courseADDICTION, Issue 4 2010Nicola C. Newton ABSTRACT Aims To establish the long-term efficacy of a universal internet-based alcohol and cannabis prevention programme in schools. Methods A cluster-randomized controlled trial was conducted to assess the effectiveness of the Climate Schools: Alcohol and Cannabis Course. The evidence-based course, aimed at reducing alcohol and cannabis use, is facilitated by the internet and consists of 12 novel and curriculum consistent lessons delivered over 6 months. Participants A total of 764 year 8 students (13 years) from 10 Australian secondary schools were allocated randomly to the internet-based prevention programme (n = 397, five schools), or to their usual health classes (n = 367, five schools). Measures Participants were assessed at baseline, immediately post, and 6 and 12 months following completion of the intervention, on measures of alcohol and cannabis knowledge, attitudes, use and related harms. Results This paper reports the final results of the intervention trial, 12 months following the completion of the Climate Schools: Alcohol and Cannabis Course. The effectiveness of the course 6 months following the intervention has been reported previously. At the 12-month follow-up, compared to the control group, students in the intervention group showed significant improvements in alcohol and cannabis knowledge, a reduction in average weekly alcohol consumption and a reduction in frequency of drinking to excess. No differences between groups were found on alcohol expectancies, cannabis attitudes or alcohol- and cannabis-related harms. The course was found to be acceptable by teachers and students as a means of delivering drug education in schools. Conclusions Internet-based prevention programs for school-age children can improve student's knowledge about alcohol and cannabis, and may also reduce alcohol use twelve months after completion. [source] A randomized controlled trial of an internet-based intervention for alcohol abusersADDICTION, Issue 12 2009John A. Cunningham ABSTRACT Objective Misuse of alcohol imposes a major public health cost, yet few problem drinkers are willing to access in-person services for alcohol abuse. The development of brief, easily accessible ways to help problem drinkers who are unwilling or unable to seek traditional treatment services could therefore have significant public health benefit. The objective of this project is to conduct a randomized controlled evaluation of the internet-based Check Your Drinking (CYD) screener ( http://www.CheckYourDrinking.net). Method Participants (n = 185) recruited through a general telephone population survey were assigned randomly to receive access to the CYD, or to a no-intervention control group. Results Follow-up rates were excellent (92%). Problem drinkers provided access to the CYD displayed a six to seven drinks reduction in their weekly alcohol consumption (a 30% reduction in typical weekly drinking) at both the 3- and 6-month follow-ups compared to a one drink per week reduction among control group respondents. Conclusions The CYD is one of a growing number of internet-based interventions with research evidence supporting its efficacy to reduce alcohol consumption. The internet could increase the range of help-seeking options available because it takes treatment to the problem drinker rather than making the problem drinker come to treatment. [source] GENETIC STUDY: Polymorphisms of the dopamine D4 receptor gene (DRD4 VNTR) and cannabinoid CB1 receptor gene (CNR1) are not strongly related to cue-reactivity after alcohol exposureADDICTION BIOLOGY, Issue 2 2007Esther Van Den Wildenberg ABSTRACT Polymorphisms in the D4 dopamine receptor gene (DRD4) and the CB1 cannabinoid receptor gene (CNR1) have been associated with a differential response to alcohol after consumption. The goal of the present study was to investigate whether heavy drinkers with these polymorphisms would respond with enhanced cue-reactivity after alcohol exposure. Eighty-eight male heavy drinkers were genotyped for the DRD4 variable number of tandem repeats (VNTR) [either DRD4 long (L) or short (S)] and the CNR1 rs2023239 polymorphism (either CT/CC or TT). Participants were exposed to water and beer in 3-minute trials. Dependent variables of main interest were subjective craving for alcohol, subjective arousal and salivary reactivity. Overall, no strong evidence was found for stronger cue-reactivity (= outcome difference between beer and water trial) in the DRD4 L and CNR1 C allele groups. The DRD4 VNTR polymorphism tended to moderate salivary reactivity such that DRD4 L participants showed a larger beverage effect than the DRD4 S participants. Unexpectedly, the DRD4 L participants reported, on average, less craving for alcohol and more subjective arousal during cue exposure, compared with the DRD4 S participants. As weekly alcohol consumption increased, the CNR1 C allele group tended to report more craving for alcohol during the alcohol exposure than the T allele group. The DRD4 and CNR1 polymorphisms do not appear to strongly moderate cue-reactivity after alcohol cue exposure, in male heavy drinkers. [source] Translating Effective Web-Based Self-Help for Problem Drinking Into the Real WorldALCOHOLISM, Issue 8 2009Heleen Riper Background:, Drinking Less (DL) is a 24/7 free-access anonymous interactive web-based self-help intervention without therapeutic guidance for adult problem drinkers in the community. In a randomized controlled trial (referred to here as DL-RCT), DL has been shown effective in reducing risky alcohol consumption. Objective:, To assess whether the findings of DL-RCT are generalizable to a naturalistic setting (DL-RW) in terms of ability to reach the target group and alcohol treatment response. Methods:, Pretest,posttest study with 6-month follow-up. An online survey was conducted of 378 of the 1,625 people who used DL-RW from May to November 2007. Primary outcome measures were (1) problem drinking, defined as alcohol consumption in the previous 4 weeks averaging >21 or >14 standard units (male/female) per week or ,6 or ,4 units (m/f) on 1 or more days per week; and (2) mean weekly alcohol consumption. DL-RW and DL-RCT data were compared and pooled. Intention-to-treat (ITT) analysis was performed to analyze and compare changes in drinking from baseline to follow-up. Results:, In the DL-RW group, 18.8% (n = 71) were drinking successfully within the limits of the Dutch guideline for low-risk drinking (p < 0.001) 6 months after baseline (ITT). The DL-RW group also decreased its mean weekly alcohol intake by 7.4 units, t(377) = 6.67, p < 0.001, d = 0.29. Drinking reduction in DL-RW was of a similar magnitude to that in the DL-RCT condition in terms of drinking within the guideline [,2(1) = 1.83, CI: 0.82,3.00, p = 0.18, RD = 0.05, OR = 1.55] and mean weekly consumption (a negligible difference of d = 0.03 in favor of DL-RW group). Conclusion:, The results from DL-RCT and DL-RW were similar, and they demonstrate that web-based self-help without therapeutic guidance is feasible, well accepted, and effective for curbing adult problem drinking in the community. [source] Brief Intervention for Female Heavy Drinkers in Routine General Practice: A 3-Year Randomized, Controlled StudyALCOHOLISM, Issue 11 2000Mauri Aalto Background: Today, heavy drinking is a common health hazard among women. The evidence in favor of providing some kind of brief intervention to reduce drinking is quite convincing. However, we do not know if intervention works in a natural environment of routine health care. The purpose of this study was to evaluate the effectiveness of long-lasting, brief alcohol intervention counseling for women in a routine general practice setting. Methods: In five primary care outpatient clinics in a Finnish town, 118 female early-phase heavy drinkers who consulted their general practitioners for various reasons were given brief alcohol intervention counseling. Intervention groups A (n= 40) and B (n= 38) were offered seven and three brief intervention sessions, respectively, over a 3-yr period. The control group C (n= 40) was advised to reduce drinking at baseline. Main outcome measures were self-reported weekly alcohol consumption, carbohydrate-deficient transferrin, mean corpuscular volume (MCV), aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyltransferase. Results: Depending on the outcome measure and the study group, clinically meaningful reduction of drinking was found in 27% to 75% of the heavy drinkers. Within all the groups, MCV significantly decreased. However, there were no statistically significant differences between study groups A, B, and C in the mean changes between the beginning and endpoint in the main outcome measures. Conclusions: The present study indicated that minimal advice, as offered to group C, was associated with reduced drinking as much as the brief intervention, as offered to groups A and B, given over a 3-yr period. Furthermore, in the routine setting of the general practice office, the effectiveness of the brief intervention may not be as good as in special research conditions. The factors possibly reducing the effectiveness in a routine setting are unknown. Thus, different methods of implementing brief intervention need to be evaluated to find better ways to support general practice personnel in their efforts to help heavy-drinking female patients to reduce their drinking. [source] Association Between the Functional Polymorphism of Catechol- O -Methyltransferase Gene and Alcohol Consumption Among Social DrinkersALCOHOLISM, Issue 2 2000Jussi Kauhanen Background: A common functional genetic polymorphism in the catechol- O -methyltransferase (COMT) gene (Val158 Met) results in 3- to 4-fold differences in COMT enzyme activity and dopamine inactivation rate. Previous studies have shown that type I alcoholism is more common among subjects with low activity COMT genotype (LL), compared with high activity (HH) or heterozygotic (LH) genotypes. Methods: We studied alcohol consumption and the COMT genotype in middle-aged Finnish men (n= 896), who represented an unselected ethnically homogenous population sample and reported using alcohol during the past year. Average alcohol use in pure ethanol (grams per week) was compared between subjects with LL genotype and subjects with LH or HH genotypes. Results: Men with LL genotype (30% of all subjects) reported 27% higher weekly alcohol consumption compared with the two other genotype groups (p < 0.05). The difference remained statistically significant after a multivariate adjustment for sociodemographic factors and prior or existing diseases (p= 0.031). Conclusions: The results indicate that COMT polymorphism may contribute significantly to alcohol intake not only in alcoholics but also in a general male population. [source] The psychological health of contractors working in war zonesJOURNAL OF TRAUMATIC STRESS, Issue 2 2009Anthony Feinstein This study examines the psychological health of contractors working in war zones. Seventy-nine contractors completed an Internet-based psychiatric assessment. The sample was exclusively male with a mean age of 43 (SD = 7) years. The number of contractors whose scores exceeded the cutoff points for depression, psychological distress, and excessive weekly alcohol consumption were 15 (20%), 21 (28%), and 13 (17%), respectively. A third of contractors had posttraumatic stress disorder (PTSD) scores in the moderate to severe range. Approximately 10% of contractors had employer-organized access to psychological help following deployment. This study provides the first empirical data showing that a significant minority of contractors working in war zones are psychologically distressed and not receiving therapy. [source] | ||||||||||
