    ABSTRACT: The purpose of the present meta-analysis was to answer the question: Can the Andrews principles of risk, needs, and responsivity, originally developed for programs that treat offenders, be extended to programs that treat drug abusers? Drawing from a dataset that included 243 independent comparisons, we conducted random-effects meta-regression and ANOVA-analog meta-analyses to test the Andrews principles by averaging crime and drug use outcomes over a diverse set of programs for drug abuse problems. For crime outcomes, in the meta-regressions the point estimates for each of the principles were substantial, consistent with previous studies of the Andrews principles. There was also a substantial point estimate for programs exhibiting a greater number of the principles. However, almost all of the 95% confidence intervals included the zero point. For drug use outcomes, in the meta-regressions the point estimates for each of the principles was approximately zero; however, the point estimate for programs exhibiting a greater number of the principles was somewhat positive. All of the estimates for the drug use principles had confidence intervals that included the zero point. This study supports previous findings from primary research studies targeting the Andrews principles that those principles are effective in reducing crime outcomes, here in meta-analytic research focused on drug treatment programs. By contrast, programs that follow the principles appear to have very little effect on drug use outcomes. Primary research studies that experimentally test the Andrews principles in drug treatment programs are recommended.

    ABSTRACT: Of the 13 principles of drug addiction treatment disseminated by the National Institute on Drug Abuse (NIDA), 7 were meta-analyzed as part of the Evidence-based Principles of Treatment (EPT) project. By averaging outcomes over the diverse programs included in the EPT, we found that 5 of the NIDA principles examined are supported: matching treatment to the client's needs, attending to the multiple needs of clients, behavioral counseling interventions, treatment plan reassessment, and counseling to reduce risk of HIV. Two of the NIDA principles are not supported: remaining in treatment for an adequate period and frequency of testing for drug use. These weak effects could be the result of the principles being stated too generally to apply to the diverse interventions and programs that exist or unmeasured moderator variables being confounded with the moderators that measured the principles. Meta-analysis should be a standard tool for developing principles of effective treatment for substance use disorders.

    ABSTRACT: Recipients of welfare benefits have elevated rates of mental health and substance-related problems relative to the general public; however, low acculturation among Latinos may be a protective factor for both conditions. Lower acculturation among Latinos is associated with lower levels of mental health and substance-related problems relative to highly acculturated individuals. To our knowledge, there are few published studies examining the potential protective effects of low acculturation, defined herein as Spanish language preference, among Latina participants in welfare programs. Screening and treatment of mental health and substance-related problems in this population are important because work requirements for benefits receipt have been implemented and mental health or substance-related problems may be barriers to meeting these requirements. This analysis assesses the prevalence of mental health and substance-related problems among female participants in California's response to 1990s federal welfare reform legislation--the California Work Opportunity and Responsibility to Kids (CalWORKs). Although mental health needs may be similar among CalWORKs recipients regardless of acculturation, substance-related problems may be less frequent among Spanish-speaking Latinas participating in the CalWORKs program. Low acculturation was not a significant predictor of mental health need but had a protective effect with regard to substance-problem risk after controlling for several other substance-problem risk variables.

    ABSTRACT: To examine the effectiveness of contingency management (CM) techniques in treating substance use disorders (i.e. illicit drugs, alcohol, tobacco). Meta-analysis was used to determine the average effect size and potential moderators in 47 comparisons of the effectiveness of CM from studies based on a treatment-control group design and published between 1970 and 2002. The mean effect size (ES) of CM was positive, with a magnitude of d = 0.42 using a fixed effects model. The magnitude of the ES declined over time, following treatment. CM was more effective in treating opiate use (d = 0.65) and cocaine use (d = 0.66), compared with tobacco (d = 0.31) or multiple drugs (d = 0.42). Larger effect sizes were associated with higher researcher involvement, earlier studies and shorter treatment duration. Study findings suggest that CM is among the more effective approaches to promoting abstinence during the treatment of substance use disorders. CM improves the ability of clients to remain abstinent, thereby allowing them to take fuller advantage of other clinical treatment components.

    ABSTRACT: A meta-analysis was conducted on 78 studies of drug treatment conducted between 1965 and 1996. Each study compared outcomes among clients who received drug treatment with outcomes among clients who received either minimal treatment or no treatment. Five methodological variables were significant predictors of effect size. Larger effect sizes were associated with studies with the following characteristics: smaller numbers of dependent variables, significant differences between groups at admission, low levels of attrition in the treatment group, a passive comparison group (no treatment, minimal treatment) as opposed to an active comparison group (standard treatment), and drug use determined by a drug test. Controlling for these methodological variables, further analyses indicated that drug abuse treatment has both a statistically significant and a clinically meaningful effect in reducing drug use and crime, and that these effects are unlikely to be due to publication bias. For substance abuse outcomes, larger effect sizes tended to be found in studies in which treatment implementation was rated high, the degree of theoretical development of the treatment was rated low, or researcher allegiance to the treatment was rated as favorable. For crime outcomes, only the average age of study participants was a significant predictor of effect size, with treatment reducing crime to a greater degree among studies with samples consisting of younger adults as opposed to older adults. Treatment modality and other variables were not related to effect sizes for either drug use or crime outcomes

    ABSTRACT: A meta-analysis was conducted on studies using a treatment-comparison group design to evaluate HIV/AIDS risk-reduction interventions for clients enrolled in drug abuse treatment programs. Overall, the interventions studied were found to have a reliable positive (weighted) effect size (d = 0.31), and this was unlikely to be due to publication bias. Effect sizes for specific categories of outcome variables were 0.31 for knowledge, attitudes, and beliefs; 0.26 for sexual behavior; 0.62 for risk-reduction skills; and 0.04 for injection practices. A number of potential moderators were examined. Effect sizes were negatively correlated with the presence of predominantly ethnic minority samples and positively correlated with the number of intervention techniques used, the intensity of the intervention, intervention delivery at a later stage of drug treatment or within methadone treatment, and the presence of a number of specific intervention techniques.

    ABSTRACT: In comparison with studies of client characteristics and treatment processes, limited research has been conducted on how program features of drug dependence treatment programs may affect client outcomes. Of particular interest are those characteristics of programs that may have a clinically significant impact on outcomes and that are amenable to change within programs. This study examines the impact of various program factors on client outcomes using data from a meta-analysis of drug dependence effectiveness studies (n = 143). Because of heterogeneity among studies, the data are analyzed in terms of type of outcome variable (drug use and crime), type of design (single-group and treatment-comparison group), and type of treatment (methadone maintenance, therapeutic communities, outpatient drug free, and detoxification). For the more valid treatment-comparison group studies, the weighted mean effect size was 0.29 for drug use outcomes and 0.17 for crime outcomes. Program factors found to be significantly correlated with effect size in one or more modalities were decade of treatment, researcher involvement in treatment delivery, maturity of the program, counselor/client ratio, treatment implementation, treatment exposure, and methadone dosage.

    ABSTRACT: This paper discusses different concepts or views of what constitutes effective treatment for drug dependence and how these views are involved in policy decisions regarding treatment. The paper reviews the rise of evidence-based medicine, discusses the emergence of efficacy research, effectiveness research, and other types of outcome-based evaluations of drug user treatment, but notes that despite a growing consensus among researchers on the effectiveness of drug user treatment, substantial public skepticism about the value of treatment still exists in the United States. The paper argues that one of the primary reasons for the lack of public consensus in the United States is that there is wide disagreement over which type of problem drug dependence is and for whom it may be a problem. The paper reviews some of the most common models and their implications for evaluating effectiveness, and argues that it is the differences in perspective among these models that are at the heart of policy debate over drug treatment policy in the United States. The paper concludes that because evaluation research as currently practiced does not address these issues, its utility for policy purposes is limited in the American context.

    ABSTRACT: Recent studies have emphasised differences in leadership styles between women and men. Women have an ldquointeractiverdquo leadership style while men are more ldquodirectiverdquo and ldquoauthoritative.rdquo Social network analysis is used to examine differences in eight mental health case management teams, half formally supervised by women and half by men. The techniques used are graphical displays and measures of centrality. Results show male leaders as the most central team member for both instrumental and expressive relations. Female leaders, however, do not adhere to a single leadership style. Team centralisation also differs with gender composition of teams influencing leadership differences.

    ABSTRACT: The authors investigated the impact of provider characteristics on the performance of clinical case managers. Case managers in a large California county were interviewed using a structured instrument that assessed service linkage, assertive outreach, and family management. Findings indicate that assertive outreach was done more often by more experienced case managers, and less often by those with larger caseloads. Belief in the efficacy of an activity was associated with doing it much more frequently.
