ESTIMATING INTERVENTION EFFECTS IN VARYING RISK SETTINGS: DO POLICE RAIDS REDUCE ILLEGAL DRUG DEALING AT NUISANCE BARS?,

CRIMINOLOGY, Issue 2 2003
JACQUELINE COHEN
This paper investigates the effectiveness of police raids in reducing drug dealing in and around nuisance bars. We examine effects of both dosage (number of raids) and duration (months) of the intervention, as well as the conditioning effects of land use and population characteristics in shaping the underlying risk levels of drug dealing in the target and surrounding areas. Results indicate that the police intervention suppresses levels of drug dealing during periods of active enforcement, but the effects largely disappear when the intervention is withdrawn. Also, the effects of the intervention are mediated by risk characteristics in target and surrounding areas. Target areas characterized by higher levels of risk are more resistant to intervention effects than those with lower levels of risk. Risk factors in nearby areas are also significant. Bars with high levels of risk arising from land uses in surrounding areas are easier to treat, while bars with high levels of population-based risk in surrounding areas are harder to treat.

A Communication Training Programme for Residential Staff Working with Adults with Challenging Behaviour: Pilot Data on Intervention Effects

JOURNAL OF APPLIED RESEARCH IN INTELLECTUAL DISABILITIES, Issue 1 2007
Andy Smidt
Background, Challenging behaviour often serves a communicative function. It therefore stands to reason that the residential staff working in developmental disability services require training to foster appropriate communicative interactions with adults with challenging behaviour. Method, Eighteen members of staff working in three residential services participated in a 4 week communication training programme. The programme focused on staff attitudes to and beliefs about challenging behaviour, communicative interactions between staff and residents and working as a team. Objective measurements were made of the effects of the training programme on staff use of augmentative and alternative communication, praise and use of inappropriate language in a multiple-baseline design across three organizations. Changes in the rate of challenging behaviours among the residents were also evaluated. Results, As staff's use of AAC and praise increased, and inappropriate language decreased, there was some concomitant decrease in residents' levels of challenging behaviour; however, these results were not sustained in the long-term. Conclusion, This pilot data suggest that an approach to staff training based on modifying attitudes and beliefs is potentially beneficial to both staff and residents. [source]


Intervention Effects on Cognitive Antecedents of Physical Exercise: A 1-Year Follow-Up Study

APPLIED PSYCHOLOGY: HEALTH AND WELL-BEING, Issue 2 2009
Wiebke Göhner
We developed and evaluated a theory-based intervention programme (MoVo-LISA) that encompasses motivational and volitional strategies aiming to prepare orthopaedic rehabilitation patients to perform physical exercise on a regular basis after discharge. The intervention consists of six units: two group sessions, one one-to-one interview, and three after-care contacts. Two hundred and twenty inactive patients were subsequently assigned to an intervention group (standard care plus MoVo-LISA) and a control group (standard care). Participants filled out questionnaires assessing cognitive antecedents of physical exercise. Measurement took place before and after rehabilitation, 6 weeks and 6 months after discharge, and 1 year after discharge. A 2 × 5 repeated measurement design was applied. Results revealed significant main and interaction effects with regard to cognitive variables; the intervention group reported enhanced self-efficacy and more positive balance of outcome expectations at 6 months as well as stronger goal intentions, more elaborated implementation intentions, and optimised strategies of intention shielding at 12 months after discharge compared to patients of the control group. Our findings demonstrate that a short and inexpensive cognitive-behavioural training programme is an effective tool to enable rehabilitation patients to follow treatment recommendations after discharge. The standardised intervention can be conducted by personnel other than psychologists. [source]


A brief alcohol intervention for hazardously drinking incarcerated women

ADDICTION, Issue 3 2010
Michael 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]


Nutrition and Physical Activity Interventions to Reduce Cardiovascular Disease Risk in Health Care Settings: A Quantitative Review with a Focus on Women

NUTRITION REVIEWS, Issue 7 2001
Sara Wilcox Ph.D.
The authors conducted a quantitative literature review of the impact of 32 diet and physical activity (PA) interventions delivered in health care settings on cardiovascular disease risk factors. Intervention effects were relatively modest but statistically significant for PA, body mass index or weight, dietary fat, blood pressure, and total and low-density lipoprotein serum cholesterol. Intervention effects were generally larger for samples with a mean age >50 years and for studies with <6 months follow-up. Type of comparison group, type of intervention, and use of a behavior theory did not have a consistent impact on intervention effects. Few studies focused on persons of color, although the results from these studies are promising. [source]

Moderators and mediators of two brief interventions for alcohol in the emergency department

ADDICTION, Issue 3 2010
Nancy P. Barnett
ABSTRACT Objective To evaluate moderators and mediators of brief alcohol interventions conducted in the emergency department. Methods Patients (18,24 years; n = 172) in an emergency department received a motivational interview with personalized feedback (MI) or feedback only (FO), with 1- and 3-month booster sessions and 6- and 12-month follow-ups. Gender, alcohol status/severity group [ALC+ only, Alcohol Use Disorders Identification Test (AUDIT+) only, ALC+/AUDIT+], attribution of alcohol in the medical event, aversiveness of the event, perceived seriousness of the event and baseline readiness to change alcohol use were evaluated as moderators of intervention efficacy. Readiness to change also was evaluated as a mediator of intervention efficacy, as were perceived risks/benefits of alcohol use, self-efficacy and alcohol treatment seeking. Results Alcohol status, attribution and readiness moderated intervention effects such that patients who had not been drinking prior to their medical event, those who had low or medium attribution for alcohol in the event and those who had low or medium readiness to change showed lower alcohol use 12 months after receiving MI compared to FO. In the AUDIT+ only group those who received MI showed lower rates of alcohol-related injury at follow-up than those who received FO. Patients who had been drinking prior to their precipitating event did not show different outcomes in the two interventions, regardless of AUDIT status. Gender did not moderate intervention efficacy and no significant mediation was found. Conclusions Findings may help practitioners target patients for whom brief interventions will be most effective. More research is needed to understand how brief interventions transmit their effects. [source]


Application of Regression-Discontinuity Analysis in Pharmaceutical Health Services Research

HEALTH SERVICES RESEARCH, Issue 2 2006
Ilene H. Zuckerman
Objective. To demonstrate how a relatively underused design, regression-discontinuity (RD), can provide robust estimates of intervention effects when stronger designs are impossible to implement. Data Sources/Study Setting. Administrative claims from a Mid-Atlantic state Medicaid program were used to evaluate the effectiveness of an educational drug utilization review intervention. Study Design. Quasi-experimental design. Data Collection/Extraction Methods. A drug utilization review study was conducted to evaluate a letter intervention to physicians treating Medicaid children with potentially excessive use of short-acting ,2 -agonist inhalers (SAB). The outcome measure is change in seasonally-adjusted SAB use 5 months pre- and postintervention. To determine if the intervention reduced monthly SAB utilization, results from an RD analysis are compared to findings from a pretest,posttest design using repeated-measure ANOVA. Principal Findings. Both analyses indicated that the intervention significantly reduced SAB use among the high users. Average monthly SAB use declined by 0.9 canisters per month (p<.001) according to the repeated-measure ANOVA and by 0.2 canisters per month (p<.001) from RD analysis. Conclusions. Regression-discontinuity design is a useful quasi-experimental methodology that has significant advantages in internal validity compared to other pre,post designs when assessing interventions in which subjects' assignment is based on cutoff scores for a critical variable.

Improving Care for Minorities: Can Quality Improvement Interventions Improve Care and Outcomes For Depressed Minorities?

HEALTH SERVICES RESEARCH, Issue 2 2003
Controlled Trial, Results of a Randomized
Objective. Ethnic minority patients often receive poorer quality care and have worse outcomes than white patients, yet practice-based approaches to reduce such disparities have not been identified. We determined whether practice-initiated quality improvement (QI) interventions for depressed primary care patients improve care across ethnic groups and reduce outcome disparities. Study Setting. The sample consists of 46 primary care practices in 6 U.S. managed care organizations; 181 clinicians; 398 Latinos, 93 African Americans, and 778 white patients with probable depressive disorder. Study Design. Matched practices were randomized to usual care or one of two QI programs that trained local experts to educate clinicians; nurses to educate, assess, and follow-up with patients; and psychotherapists to conduct Cognitive Behavioral Therapy. Patients and physicians selected treatments. Interventions featured modest accommodations for minority patients (e.g., translations, cultural training for clinicians). Data Extraction Methods. Multilevel logistic regression analyses assessed intervention effects within and among ethnic groups. Principal Findings. At baseline, all ethnic groups (Latino, African American, white) had low to moderate rates of appropriate care and the interventions significantly improved appropriate care at six months (by 8,20 percentage points) within each ethnic group, with no significant difference in response by ethnic group. The interventions significantly decreased the likelihood that Latinos and African Americans would report probable depression at months 6 and 12; the white intervention sample did not differ from controls in reported probable depression at either follow-up. While the intervention significantly improved the rate of employment for whites and not for minorities, precision was low for comparing intervention response on this outcome. It is important to note that minorities remained less likely to have appropriate care and more likely to be depressed than white patients. Conclusions. Implementation of quality improvement interventions that have modest accommodations for minority patients can improve quality of care for whites and underserved minorities alike, while minorities may be especially likely to benefit clinically. Further research needs to clarify whether employment benefits are limited to whites and if so, whether this represents a difference in opportunities. Quality improvement programs appear to improve quality of care without increasing disparities, and may offer an approach to reduce health disparities. [source]


Preventing preschool externalizing behavior problems through video-feedback intervention in infancy

INFANT MENTAL HEALTH JOURNAL, Issue 5 2006
Mariska Klein Velderman
In the present study (1) intervention effects on children's preschool behavior problems were evaluated in a high risk sample with an overrepresentation of insecure adult attachment representations in 77 first-time mothers, and (2) predictors and correlates of child problem behavior were examined. Early short-term video-feedback intervention to promote positive parenting (VIPP) focusing on maternal sensitivity and implemented in the baby's first year of life significantly protected children from developing clinical Total Problems at preschool age. Also, compared with the control group, fewer VIPP children scored in the clinical range for Externalizing Problems. No intervention effects on Internalizing clinical problem behavior were found. The VIPP effects on Externalizing and Total clinical Problems were not mediated by VIPP effects on sensitivity and infant attachment or moderated by mother or child variables. Maternal satisfaction with perceived support appeared to be associated with less children's Internalizing, Externalizing, and Total Problems. More research is needed to find the mechanisms triggered by VIPP, but the outcomes could be considered as promising first steps in the prevention of disturbing, externalizing behavior problems in young children.

A modelling strategy for the analysis of clinical trials with partly missing longitudinal data

INTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 3 2003
Ian R. White
Abstract Standard statistical analyses of randomized controlled trials with partially missing outcome data often exclude valuable information from individuals with incomplete follow-up. This may lead to biased estimates of the intervention effect and loss of precision. We consider a randomized trial with a repeatedly measured outcome, in which the value of the outcome on the final occasion is of primary interest. We propose a modelling strategy in which the model is successively extended to include baseline values of the outcome, then intermediate values of the outcome, and finally values of other outcome variables. Likelihood-based estimation of random effects models is used, allowing the incorporation of data from individuals with some missing outcomes. Each estimated intervention effect is free of non-response bias under a different missing-at-random assumption. These assumptions become more plausible as the more complex models are fitted, so we propose using the trend in estimated intervention effects to assess the nature of any non-response bias. The methods are applied to data from a trial comparing intensive case management with standard case management for severely psychotic patients. All models give similar estimates of the intervention effect and we conclude that non-response bias is likely to be small. Copyright © 2003 Whurr Publishers Ltd. [source]


Follow-up of serious offender patients in the community: multiple methods of tracing

INTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 3 2002
Elizabeth Jamieson Lecturer
Abstract Longitudinal studies of people with mental disorder are important in understanding outcome and intervention effects but attrition rates can be high. This study aimed to evaluate use of multiple record sources to trace, over 12 years, a one-year discharge cohort of high-security hospital patients. Everyone leaving such a hospital in 1984 was traced until a census date of 31 December 1995. Data were collected from several national databases (Office for National Statistics (ONS), Home Office (HO) Offenders' Index, Police National Computer Records, the Electoral Roll) and by hand-searching responsible agency records (HO, National Health Service). Using all methods, only three of the 204 patients had no follow-up information. Home Office Mental Health Unit data were an excellent source, but only for people still under discharge restrictions (<50% after eight years). Sequential tracing of hospital placements for people never or no longer under such restrictions was laborious and also produced only group-specific yield. The best indicator of community residence was ONS information on general practitioner (GP/primary care) registration. The electoral roll was useful when other sources were exhausted. Follow-up of offenders/offender-patients has generally focused on event data, such as re-offending. People untraced by that method alone, however, are unlikely to be lost to follow-up on casting a wider records net. Using multiple records, attrition at the census was 38%, but, after certain assumptions, reduced further to 5%. Copyright © 2002 Whurr Publishers Ltd. [source]


Lack of Effect of Tai Chi Chuan in Preventing Falls in Elderly People Living at Home: A Randomized Clinical Trial

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 1 2009
Inge H. J. Logghe MSc
OBJECTIVES: To evaluate the effectiveness of Tai Chi Chuan in fall prevention in elderly people living at home with a high risk of falling. DESIGN: Randomized controlled trial. SETTING: Two industrial towns in the western part of the Netherlands. PARTICIPANTS: Two hundred sixty-nine elderly people (average age 77) living at home with a high risk of falling. INTERVENTIONS: The intervention group received Tai Chi Chuan training for 1 hour twice a week for 13 weeks; the control group received usual care. Both groups received a brochure containing general information on how to prevent fall incidents. MEASUREMENTS: Primary outcome was the number of falls over 12 months. Secondary outcomes were balance, fear of falling, blood pressure, heart rate at rest, forced expiratory volume during the first second, peak expiratory flow, physical activity, and functional status. RESULTS: After 12 months, no lower fall risk in the Tai Chi Chuan group was observed than in the control group (adjusted hazard ratio=1.16; 95% confidence interval=0.84,1.60), and there were no significant intervention effects on the secondary outcome measures. CONCLUSION: These results suggest that Tai Chi Chuan may not be effective in elderly people at a high risk of falling who live at home. [source]


Bone Mineral Response to a 7-Month Randomized Controlled, School-Based Jumping Intervention in 121 Prepubertal Boys: Associations With Ethnicity and Body Mass Index,

JOURNAL OF BONE AND MINERAL RESEARCH, Issue 5 2002
K. J. Mackelvie
Abstract We examined the effects of a 7-month jumping intervention (10 minutes, 3 times per week) on bone mineral gain in prepubertal Asian and white boys (10.3 ± 0.6 years, 36.0 ± 9.2 kg) at 14 schools randomized to control (n = 60) and intervention (n = 61) groups. Intervention and control groups had similar mean baseline and change in height, weight, lean mass and fat mass, baseline areal bone mineral density (aBMD; g/cm2), bone mineral content (BMC; g; dual-energy X-ray absorptiometry [DXA], QDR 4500W), and similar average physical activity and calcium intakes. Over 7 months, the intervention group gained more total body (TB) BMC (1.6%, p < 0.01) and proximal femur (PF) aBMD (1%, p < 0.05) than the control group after adjusting for age, baseline weight, change in height, and loaded physical activity. We also investigated the 41 Asian and 50 white boys (10.2 ± 0.6 years and 31.9 ± 4.4 kg) who were below the 75th percentile (19.4 kg/m2) of the cohort mean for baseline body mass index (BMI). Boys in the intervention group gained significantly more TB and lumbar spine (LS) BMC, PF aBMD, and trochanteric (TR) aBMD (+ ,2%) than boys in the control group (adjusted for baseline weight, final Tanner stage, change in height, and loaded physical activity). Bone changes were similar between Asians and whites. Finally, we compared the boys in the control group (n = 16) and the boys in the intervention group (n = 14) whose baseline BMI fell in the highest quartile (10.5 ± 0.6 years and 49.1 ± 8.2 kg). Seven-month bone changes (adjusted as aforementioned) were similar in the control and intervention groups. In summary, jumping exercise augmented bone mineral accrual at several regions equally in prepubertal Asian and white boys of average or low BMI, and intervention effects on bone mineral were undetectable in high BMI prepubertal boys.

I think therefore i om: cognitive distortions and coping style as mediators for the effects of mindfulness meditation on anxiety, positive and negative affect, and hope

JOURNAL OF CLINICAL PSYCHOLOGY, Issue 6 2009
Sharon Sears
Abstract This study examined cognitive distortions and coping styles as potential mediators for the effects of mindfulness meditation on anxiety, negative affect, positive affect, and hope in college students. Our pre- and postintervention design had four conditions: control, brief meditation focused on attention, brief meditation focused on loving kindness, and longer meditation combining both attentional and loving kindness aspects of mindfulness. Each group met weekly over the course of a semester. Longer combined meditation significantly reduced anxiety and negative affect and increased hope. Changes in cognitive distortions mediated intervention effects for anxiety, negative affect, and hope. Further research is needed to determine differential effects of types of meditation. © 2009 Wiley Periodicals, Inc. J Clin Psychol 65: 1,13, 2009. [source]


Recommendations for assessing Patient-Reported Outcomes and Health-Related quality of life in clinical trials on allergy: a GA2LEN taskforce position paper

Recommendations for assessing Patient-Reported Outcomes and Health-Related quality of life in clinical trials on allergy: a GA2LEN taskforce position paper. Allergy 2010; 65: 290,295. Abstract The aim of this Global Allergy and Asthma European Network (GA2LEN) consensus report is to provide recommendations for patient-reported outcomes (PROs) evaluation in clinical trials for allergic diseases, which constitute a global health problem in terms of physical, psychological economic and social impact. During the last 40 years, PROs have gained large consideration and use in the scientific community, to gain a better understanding of patients' subjective assessment with respect to elements concerning their health condition. They include all health-related reports coming from the patient, without involvement or interpretation by physician or others. PROs assessment should be performed by validated tools (disease-specific tools when available or generic ones) selected taking into account the aim of the study, the expected intervention effects and the determinant and confounding factors or patient-related factors which could influence PROs. Moreover, each tool should be used exclusively in the patient population following the authors' indications without modification and performing a cross-cultural validation if the tool must be used in a language that differs from the original. The result analysis also suggests that the relevance of PROs results in any interventional study should include a pre,post assessment providing information concerning statistical differences within or among groups, rates of response for the PROs and a minimal important difference for the population. The report underlines the importance of further investigation on some topics, such as the quality assessment of existing PROs tools, the definition of inclusion and exclusion criteria and a more extensive evaluation of the correlation between PROs, besides health-related quality of life, and clinical data.

Policy implementation: Implications for evaluation

NEW DIRECTIONS FOR EVALUATION, Issue 124 2009
Amy DeGroff
Policy implementation reflects a complex change process where government decisions are transformed into programs, procedures, regulations, or practices aimed at social betterment. Three factors affecting contemporary implementation processes are explored: networked governance, sociopolitical context and the democratic turn, and new public management. This frame of reference invites evaluators to consider challenges present when evaluating macrolevel change processes, such as the inherent complexity of health and social problems, multiple actors with variable degrees of power and influence, and a political environment that emphasizes accountability. The evaluator requires a deep and cogent understanding of the health or social issues involved; strong analysis and facilitation skills to deal with a multiplicity of values, interests, and agendas; and a comprehensive toolbox of evaluation approaches and methods, including network analysis to assess and track the interconnectedness of key champions (and saboteurs) who might affect intervention effects and sustainability. © Wiley Periodicals, Inc., and the American Evaluation Association.

Efficacy and safety of donepezil in patients with dementia with Lewy bodies: Preliminary findings from an open-label study

PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 2 2006
SATORU MORI md
Abstract, The objectives of the present study were first to determine the feasibility of conducting a randomized clinical trial of 5 mg/day donepezil in patients with mild to moderate dementia with Lewy bodies (DLB) and second, to obtain preliminary data of possible intervention effects. Twelve patients with probable DLB were evaluated at weeks 4, 8, and 12 using modified Neuropsychiatric Inventory (NPI) with an extra domain to additionally evaluate fluctuation in cognitive functions (NPI-11); the Japanese version of Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-J cog); and the Unified Parkinson's Disease Rating Scale (UPDRS). The NPI-11 scores were significantly improved at weeks 8 and 12 compared with baseline. Despite a significant improvement in ADAS-J-cog at week 4, no more improvement was noted thereafter. Deterioration was not noted in UPDRS scores. Donepezil is expected to be therapeutically useful and safe in treating DLB patients, indicating marked improvements in behavioral and psychological symptoms of dementia (BPSD) rather than in cognitive deficit, without deteriorating parkinsonism.

Psychosocial interventions and quality of life in gynaecological cancer patients: a systematic review

PSYCHO-ONCOLOGY, Issue 8 2009
Jolyn Hersch
Abstract Objective: Women with gynaecological cancer are at risk of poor quality of life outcomes. Although various psychosocial interventions have been developed to address these concerns, such interventions have not yet been systematically evaluated in this population. The current review provides an up-to-date and comprehensive summary of the evidence regarding the effectiveness of psychosocial interventions in women with gynaecological cancers. Methods: Relevant studies were identified via Medline, CINAHL, and PsycINFO databases (1980 to June 2008), reference lists of articles and reviews, grey literature databases, and consultations with physicians and other experts in the field. Only controlled trials comparing a psychosocial intervention with a control group in a gynaecological cancer population, with at least one quality of life variable as a main outcome, were included in the review. Two authors independently assessed trial quality and extracted data. Results: Twenty-two studies involving 1926 participants were included. There was substantial variability in study quality and results. Evidence was mixed regarding intervention effects on social and sexual functioning, distress, depression, anxiety, attitude to medical care, self-esteem and body image. Interventions generally did not improve physical or vocational outcomes. Conclusions: There was limited evidence in support of healing touch, whereas information-based interventions seemed largely unable to provide meaningful benefits. Cognitive-behavioural interventions had some positive effects. Counselling appeared to be the most promising intervention strategy for addressing quality of life concerns for women with gynaecological cancers. Copyright © 2008 John Wiley & Sons, Ltd. [source]


Joint attention training for children with autism using behavior modification procedures

THE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 3 2003
Christina Whalen
Background: Deficits in joint attention are considered by many researchers to be an early predictor of childhood autism (e.g., Osterling & Dawson, 1994) and are considered to be pivotal to deficits in language, play, and social development in this population (Mundy, 1995). Although many researchers have noted the importance of joint attention deficits in the development of children with autism (e.g., Mundy, Sigman, & Kasari, 1994) and have called for intervention strategies (e.g., Mundy & Crowson, 1997), few studies have attempted to target joint attention. In this study, joint attention behaviors were taught to children with autism using a behavior modification procedure. Methods: A multiple-baseline design was implemented to evaluate intervention effects. The following target behaviors were included in the intervention: 1) Responding to showing, pointing, and gaze shifting of adult; 2) Coordinated gaze shifting (i.e., coordinated joint attention); and 3) Pointing (with the purpose of sharing, not requesting). Generalization to setting and parent, follow-up sessions, and social validation measures were also analyzed. Results: Joint attention behaviors were effectively trained and targeted behaviors generalized to other settings. In addition, positive changes were noted by naïve observers using social validation measures. Conclusions: Integrating joint attention training into existing interventions may be important for children with autism. In addition, training parents in these techniques may help to maintain joint attention skills outside of the treatment setting. [source]


Can rational prescribing be improved by an outcome-based educational approach?

THE JOURNAL OF CONTINUING EDUCATION IN THE HEALTH PROFESSIONS, Issue 1 2010
A randomized trial completed in Iran
Abstract Introduction: An outcome-based education approach has been proposed to develop more effective continuing medical education (CME) programs. We have used this approach in developing an outcome-based educational intervention for general physicians working in primary care (GPs) and evaluated its effectiveness compared with a concurrent CME program in the field of rational prescribing. Methods: A cluster randomized controlled design was used. All 159 GPs working in 6 cities, in 2 regions in East Azerbaijan province in Iran, were invited to participate. The cities were matched and randomly divided into an intervention arm, for an outcome-based education on rational prescribing, and a control arm for a traditional CME program on the same topic. GPs' prescribing behavior was assessed 9 months before, and 3 months after the CME programs. Results: In total, 112 GPs participated. The GPs in the intervention arm significantly reduced the total number of prescribed drugs and the number of injections per prescription. The GPs in the intervention arm also increased their compliance with specific requirements for a correct prescription, such as explanation of specific time and manner of intake and precautions necessary when using drugs, with significant intervention effects of 13, 36, and 42 percentage units, respectively. Compared with the control arm, there was no significant improvement when prescribing antibiotics and anti-inflammatory agents. Discussion: Rational prescribing improved in some of the important outcome-based indicators, but several indicators were still suboptimal. The introduction of an outcome-based approach in CME seems promising when creating programs to improve GPs' prescribing behavior. [source]


Validation of the WHOQOL-BREF among women following childbirth

AUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 2 2010
Joan WEBSTER
Background:, There is increasing interest in measuring quality of life (QOL) in clinical settings and in clinical trials. None of the commonly used QOL instruments has been validated for use postnatally. Aim:, To assess the psychometric properties of the 26-item WHOQOL-BREF (short version of the World Health Organization Quality of Life assessment) among women following childbirth. Methods:, Using a prospective cohort design, we recruited 320 women within the first few days of childbirth. At six weeks postpartum, participants were asked to complete the WHOQOL-BREF, the Edinburgh Postnatal Depression Index and the Australian Unity Wellbeing Index. Validation of the WHOQOL-BREF included an analysis of internal consistency, discriminate validity, convergent validity and an examination of the domain structure. Results:, In all, 221 (69.1%) women returned their six-week questionnaire. All domains of the WHOQOL-BREF met reliability standards (alpha coefficient exceeding 0.70). The questionnaire discriminated well between known groups (depressed women and non-depressed women. P , 0.000) and demonstrated satisfactory correlations with the Australian Unity Wellbeing index (r , 0.45). The domain structure of the WHOQOL-BREF was also valid in this population of new mothers, with moderate-to-high correlation between individual items and the domain structure to which the items were originally assigned. Conclusion:, The WHOQOL-BRF is a well-accepted and valid instrument in this population and may be used in postnatal clinical settings or for assessing intervention effects in research studies.

Modelling Multivariate Outcomes in Hierarchical Data, with Application to Cluster Randomised Trials

BIOMETRICAL JOURNAL, Issue 3 2006
Rebecca M. Turner
Abstract In the cluster randomised study design, the data collected have a hierarchical structure and often include multivariate outcomes. We present a flexible modelling strategy that permits several normally distributed outcomes to be analysed simultaneously, in which intervention effects as well as individual-level and cluster-level between-outcome correlations are estimated. This is implemented in a Bayesian framework which has several advantages over a classical approach, for example in providing credible intervals for functions of model parameters and in allowing informative priors for the intracluster correlation coefficients. In order to declare such informative prior distributions, and fit models in which the between-outcome covariance matrices are constrained, priors on parameters within the covariance matrices are required. Careful specification is necessary however, in order to maintain non-negative definiteness and symmetry between the different outcomes. We propose a novel solution in the case of three multivariate outcomes, and present a modified existing approach and novel alternative for four or more outcomes. The methods are applied to an example of a cluster randomised trial in the prevention of coronary heart disease. The modelling strategy presented would also be useful in other situations involving hierarchical multivariate outcomes. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) [source]


School,Based Early Intervention and Later Child Maltreatment in the Chicago Longitudinal Study

CHILD DEVELOPMENT, Issue 1 2003
Arthur J. Reynolds
Investigated were the effects of participation in the Title I Child,Parent Centers (CPC) on substantiated reports of child maltreatment for 1,408 children (93% of whom are African American) in the Chicago Longitudinal Study. The CPCs provide child education and family support services in high,poverty areas. After adjusting for preprogram maltreatment and background factors, 913 preschool participants had significantly lower rates of court petitions of maltreatment by age 17 than 495 children of the same age who participated in alternative kindergarten interventions (5.0% vs. 10.5%, a 52% reduction). Participation for 4 to 6 years was significantly associated with lower rates of maltreatment (3.6% vs. 6.9%, a 33% reduction). Findings based on child protective service records (as well as combined protective service and court records) were similar. Preschool length, family risk, and school poverty were associated with lower rates of maltreatment. Parental involvement in school and school mobility were significant mediators of intervention effects. [source]


Three-month Follow-up of Brief Computerized and Therapist Interventions for Alcohol and Violence Among Teens

ACADEMIC EMERGENCY MEDICINE, Issue 11 2009
Rebecca M. Cunningham MD
Abstract Objectives:, Alcohol use and violent behaviors are well documented among adolescents and have enormous effects on morbidity and mortality. The authors hypothesized that universal computer screening of teens in an inner-city emergency department (ED), followed by a brief intervention (BI), would be 1) feasible (as measured by participation and completion of BI during the ED visit) and well received by teens (as measured by posttest process measures of intervention acceptability) and 2) effective at changing known precursors to behavior change such as attitudes, self-efficacy, and readiness to change alcohol use and violence. Methods:, Adolescent patients (ages 14,18 years) at an urban ED were approached to complete a computerized survey. The survey was conducted daily from 12 noon to 11 pm from September 2006 through November 2008. Adolescents reporting both alcohol use and violence in the past year were randomized to a control group or a 35-minute BI delivered by a computer or therapist as part of the SafERteens study. Validated measures were administered, including demographics, alcohol use, attitudes toward alcohol and violence, self-efficacy for alcohol and violence, readiness to change alcohol and violence, and process questions, including likeability of intervention. Results:, A total of 2,423 adolescents were screened. Thirteen percent of those approached refused. The population was 45% male, 58% African American, and 6.2% Hispanic. Of those screened, 637 adolescents (26%) screened positive; 533 were randomized to participate, and 515 completed the BI prior to discharge. The BIs were well received by the adolescents overall; 97% of those randomized to a BI self-reported that they found one intervention section "very helpful." At posttest, significant reductions in positive attitudes for alcohol use and violence and significant increases in self-efficacy related to alcohol/violence were found for both therapist and computer interventions. At 3-month follow-up there was 81% retention, and generalized estimating equations (GEE) analysis showed that participants in both interventions had significant reductions in positive attitudes for alcohol use (therapist p = 0.002, computer p = 0.0001) and violence (therapist p = 0.012, computer p = 0.007) and significant increases in self-efficacy related to violence (therapist p = 0.0.04, computer p = 0.002); alcohol self-efficacy improved in the therapist BI condition only (therapist p = 0.050, computer p = 0.083). Readiness to change was not significantly improved. Conclusions:, This initial evaluation of the SafERteens study shows that universal computerized screening and BI for multiple risk behaviors among adolescents is feasible, well received, and effective at altering attitudes and self-efficacy. Future evaluations of the SafERteens study will evaluate the interventions' effects on behavioral change (alcohol use and violence) over the year following the ED visit. [source]
