This meta-analysis tested the major theoretical assumptions about behavior change by examining the outcomes and mediating mechanisms of different preventive strategies in a sample of 354 HIV-prevention interventions and 99 control groups, spanning the past 17 years. There were 2 main conclusions from this extensive review. First, the most effective(More)
This meta-analysis (N = 110,092) assessed the efficacy of HIV-prevention interventions across samples with higher and lower concentrations of Latinos/Latin Americans. Findings indicated that groups with higher percents of Latinos increased condom and HIV-related knowledge to a lesser extent than groups with lower percents of Latinos/ Latin Americans.(More)
A meta-analysis of 166 HIV-prevention interventions tested theoretical predictions about the effects of experts, lay community members, and similar and dissimilar others, as agents of change. In general, expert interventionists produced greater behavior change than lay community members, and the demographic and behavioral similarity between the(More)
A meta-analysis of 150 research reports summarizing the results of multiple behavior domain interventions examined theoretical predictions about the effects of the included number of recommendations on behavioral and clinical change in the domains of smoking, diet, and physical activity. The meta-analysis yielded 3 main conclusions. First, there is a(More)
This meta-analysis examines whether exposure to HIV-prevention interventions follows self-validation or risk-reduction motives. The dependent measures used in the study were enrolling in an HIV-prevention program and completing the program. Results indicated that first samples with low prior condom use were less likely to enroll than samples with high prior(More)
This research tested the prediction that reading a preventive brochure leads people to watch a preventive video, and that watching this video in turn leads to an increase in the likelihood of participating in a preventive counseling session. A sample of men and women from a southeastern community in the United States was recruited for a general health(More)
HIV-prevention intervention effectiveness depends on understanding whether clients with highest need for HIV-prevention counseling accept it. With this objective, a field study with a high-risk community sample from the southeastern United States (N = 350) investigated whether initial knowledge about HIV, motivation to use condoms, condom-use-relevant(More)
OBJECTIVE Enrollment in HIV-prevention interventions is more likely when the audience has safer rather than riskier HIV-relevant behavior. Thus, a meta-intervention was designed to increase participation by an audience of infrequent condom users in Florida. DESIGN Participants (N = 400) were randomly assigned to 1 of 4 conditions varying the introduction(More)
Although experimental behavioral interventions to prevent HIV are generally designed to correct undesirable epidemiological trends, it is presently unknown whether the resulting body of behavioral interventions is adequate to correct the social disparities in HIV-prevalence and incidence present in the United States. Two large, diverse-population(More)
OBJECTIVE A meta-analysis was conducted to test theoretical hypotheses about the predictors of enrollment and completion of condom-use-promotion interventions among men and women. DESIGN A meta-analysis summarized research reports of the efficacy of experimental interventions on human immunodeficiency virus (HIV) prevention. MAIN OUTCOME MEASURES The(More)
