A systematic review and meta-analysis of strategies to promote vaccination uptake.

Although immunization can dramatically curb the mortality and morbidity associated with vaccine-preventable diseases, vaccination uptake remains suboptimal in many areas of the world. Here, in this meta-analysis, we analysed the results from 88 eligible randomized controlled trials testing interventions to increase vaccination uptake with 1,628,768 participants from 17 countries with variable development levels (for example, Human Development Index ranging from 0.485 to 0.

A meta-intervention to increase completion of an HIV-prevention intervention: Results from a randomized controlled trial in the state of Florida.

Objective: A randomized control trial with 722 eligible clients from a health department in the State of Florida was conducted to identify a simple, effective meta-intervention to increase completion of an HIV-prevention counseling program.

Method: The overall design involved 2 factors representing an empowering and instrumental message, as well as an additional factor indicating presence or absence of expectations about the counseling. Completion of the 3-session counseling was determined by recording attendance.

Motivational barriers to retention of at-risk young adults in HIV-prevention interventions: perceived pressure and efficacy.

Multi-session HIV-prevention interventions are efficacious but depend on the retention of clients over time. In a sample of at-risk young adults (N = 386), we investigated three potential motivational barriers that might affect the likelihood of retention. Perceived pressure, perceived efficacy and fear and anxiety during the initial session were measured, along with demographic characteristics, partner characteristics, and HIV-related health knowledge.

When is Retention in Health Promotion Interventions Intentional? Predicting Return to Health Promotion Interventions as a Function of Busyness.

To test when intentional decisions enhance retention in health-promotion interventions, we analyzed the rate of return of 278 clients of HIV-prevention counseling at a state health department in Florida. Specifically, the role of intentions as a facilitator of returns was analyzed as a function of busyness (more children and work hours), while demographic and health factors that also influenced returns were controlled for. Consistent with the notion that actions depend on ability, intentions predicted the behavior of the less busy participants but failed to facilitate retention when participants were occupied with children and work.

Reducing cultural and psychological barriers to Latino enrollment in HIV-prevention counseling: initial data on an enrollment meta-intervention.

Aspects of Latino culture (e.g., machismo, marianism) can act as barriers to enrollment in HIV-prevention programs.

Men and women have specific needs that facilitate enrollment in HIV-prevention counseling.

Although reducing HIV risk is a primary motive for the design of HIV prevention interventions, the goals of the clients may be very different. Social theories of gender suggest that women, who often seek to resolve social and relational problems, may see HIV-prevention counseling as a mean of resolving partner violence. In contrast, men, who often worry about their physical strength, may seek to enroll in HIV-prevention programs when they experience physical symptoms unrelated to HIV.

Are we going to close social gaps in HIV? Likely effects of behavioral HIV-prevention interventions on health disparities.

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 meta-analytic databases were reanalyzed to estimate potential perpetuation and change in demographic and behavioral gaps as a result of introducing the available behavioral interventions advocating condom use. This review suggested that, if uniformly applied across populations, the analyzed set of experimental (i.

Material and social incentives to participation in behavioral interventions: a meta-analysis of gender disparities in enrollment and retention in experimental human immunodeficiency virus prevention interventions.

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 outcome measure consisted of (a) a measure of participation, obtained by subtracting the actual number of participants from the number of the invited people, and (b) a measure of retention was obtained by subtracting the number of participants who completed the intervention from the number of commencers.

Participation in counseling programs: high-risk participants are reluctant to accept HIV-prevention counseling.

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 behavioral skills, and prior condom use correlate with subsequent acceptance of an HIV-prevention counseling session. Ironically, participants with high (vs.

Beyond the most willing audiences: a meta-intervention to increase exposure to HIV-prevention programs by vulnerable populations.

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 to a counseling program.

From brochures to videos to counseling: exposure to HIV-prevention programs.

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 survey with the objective of examining participation in HIV-prevention interventions. Unobtrusive measures of exposure to HIV-prevention brochures, an HIV-prevention video, and an HIV-prevention counseling session were obtained.

Who participates in which health promotion programs? A meta-analysis of motivations underlying enrollment and retention in HIV-prevention interventions.

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 condom use.

Conceptualizing the Influence of Social Agents of Behavior Change: A Meta-Analysis of the Effectiveness of HIV-Prevention Interventionists for Different Groups.

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 interventionist and the recipients facilitated behavioral change. Equally importantly, there were differences across groups in the efficacy of various sources, especially among populations of low status and/or power.

A test of major assumptions about behavior change: a comprehensive look at the effects of passive and active HIV-prevention interventions since the beginning of the epidemic.

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 interventions were those that contained attitudinal arguments, educational information, behavioral skills arguments, and behavioral skills training, whereas the least effective ones were those that attempted to induce fear of HIV.
