Increasing condom use: evaluation of a theory-based intervention to prevent sexually transmitted diseases in young women

[Effectiveness of structural interventions to promote condom use in adolescents and young people: Systematic Review]

OBJECTIVE

Evaluate the effectiveness of structural or multicomponent interventions aimed at increasing the use of condoms in adolescents and young adults, identifying the strategies that form the interventions evaluated, and recognizing the theoretical models that support these interventions.

METHODOLOGY

Design: Systematic review of literature. Data source: MEDLINE databases were consulted via OVID, Embase, and CENTRAL in order to search for studies on interventions aimed at increasing the use of condoms in adolescents and young adults. Selection of studies: A total of 7 primary investigations were selected, in which the effect of a structured or multicomponent intervention to increase the use of condoms in adolescents and young adults was evaluated. The quality of the studies was evaluated using the Cochrane bias risk assessment.

RESULTS

Five investigations show changes in the percentages of condom use with values between 53% and 68%. The interventions targeted guided their actions more at individual level with strategies such as sexual health education, reproductive health counseling, knowledge about the condom, knowledge about STIs / HIV, than at organizational and environ-mental levels, which were aimed at the provision of condoms. The theoretical models proposed in the studies are focused on human behavior, individual behavior, and social learning.

CONCLUSION

Structural interventions that aim to increase the use of condoms in adolescents and young adults seem to show significant changes at individual level, but possible changes generated at both organization and environment levels are unknown.

Dismantling the theory of planned behavior: evaluating the relative effectiveness of attempts to uniquely change attitudes, norms, and perceived behavioral control

The current study compares the effectiveness of interventions that attempted to uniquely influence hypothesized determinants of behavior in the Theory of Planned Behavior versus some optimal combination of constructs (three constructs vs. four) to increase condom use among intentions and behavior college students. 317 participants (M_age = 19.31; SD_age = 1.31; 53.3% female; 74.1% Caucasian) were randomly assigned to one of seven computer-based interventions. Interventions were designed using the Theory of Planned Behavior as the guiding theoretical framework. 196 (61.8%) completed behavioral follow-up assessments 3-month later. We found that the four construct intervention was marginally better at changing intentions (estimate = - .06, SE = .03, p = .06), but the single construct interventions were more strongly related to risky sexual behavior at follow-up (estimate = .04, SE = .02, p = .05). This study suggests that these constructs may work together synergistically to produce change (ClinicalTrials.gov Number NCT# 02855489).

Single-Session Behavioral Interventions for Sexual Risk Reduction: A Meta-Analysis

BACKGROUND

Evidence-based, single-session STI/HIV interventions to reduce sexual risk taking are potentially effective options for implementation in resource-limited settings and may solve problems associated with poor participant retention.

PURPOSE

The purpose of the study is to estimate the efficacy of single-session, behavioral interventions in reducing unprotected sex or increasing condom use.

METHODS

Data sources were searched through April 2013 producing 67 single-session interventions (52 unique reports; N = 20,039) that included outcomes on condom use and/or unprotected sex.

RESULTS

Overall, participants in single-session interventions reduced sexual risk taking relative to control groups (d ₊  = 0.19, 95 % CI = 0.11, 0.27). Within-group effects of the interventions were larger than the between-groups effects when compared to controls.

CONCLUSIONS

Brief, targeted single-session sexual risk reduction interventions demonstrate a small but significant effect and should be prioritized.

A Brief Report: Lessons Learned and Preliminary Findings of Progreso en Salud, an HIV Risk Reduction Intervention for Latina Seasonal Farmworkers

Throughout the past decade, HIV rates in Florida—particularly South Florida, where many Latina seasonal farmworkers reside and work—have ranked among the highest in the nation. In this brief report, we delineate important lessons learned and preliminary findings from the implementation of the HIV prevention intervention Progreso en Salud (Progress in Health). Among the 114 Latina seasonal farmworker participants, there were significant increases from baseline to 6-month follow-up in the percentages of overall condom use, HIV testing, HIV/AIDS-related communications with friends, HIV knowledge, condom use self-efficacy, and correct use of condoms. Lessons learned from this study can be used to inform future HIV intervention strategies to improve the adoption and maintenance of HIV risk reduction behaviors among high-risk Latina seasonal workers and other high-risk underserved populations. Future research is needed to support our findings.

Changing the Context Is Important and Necessary, but Not Sufficient, for Reducing Adolescent Risky Sexual Behavior: A Reply to Steinberg (2015)

Starting school later, keeping adolescents busy with structured programming, and making free condoms available, as Steinberg (2015) suggests, are important and necessary steps, but they are simply not sufficient if the goal is reducing sexually transmitted infections and unplanned pregnancy. We agree that the current state of affairs, which in many schools involves sexuality education using programs that are not empirically supported, is unacceptable. However, abandoning sexuality education entirely would leave adolescents ill equipped to protect themselves. Despite the fact that current intervention technology is neither perfect nor optimally effective, there are empirically supported, school-based sexual risk reduction interventions that teach these skills and are readily available. In addition, even though we agree that structured afternoon programs for school-aged adolescents would reduce the opportunity for sexual risk behavior during the school years, such programs would not address the demographic reality of sexual risk that continues for adolescents and emerging adults far past the end of traditional secondary education. We believe Steinberg's suggestions are an excellent start and ought to be implemented. But complementary to this approach should be the use of existing empirically supported sexual risk reduction interventions and research into the development of even more effective interventions.

Measurement invariance of alcohol instruments with Hispanic youth

INTRODUCTION

Despite their widespread use across clinical and research settings, no study has yet investigated the fit of several standard alcohol measures for Hispanic youth, including those used to assess motivation to change, self-efficacy, peer norms, and problem drinking. This study thus served to address this gap by evaluating measurement invariance with substance-using youth.

METHODS

We enrolled a large sample of regular substance-using youth who were involved with the justice system (N=368; 72.9% male; 76.9% Hispanic; M age=16.17years). Similar to the broader Hispanic population of the southwest United States (U.S.), Hispanic youth in the sample were on average 3.5th generation (with at least 1 foreign-born grand-parent). Following standard administration and scoring procedures, all youth completed measures of motivation to change (e.g., readiness rulers, intentions to change), self-efficacy (e.g., drink refusal in social situations), peer norms (e.g., peer norms for substance use), and problem drinking (e.g., substance use quantity/frequency; Alcohol Use Disorders Identification Test; Rutgers Alcohol Problems Index; Timeline FollowBack). Measurement equivalence was evaluated via multiple group confirmatory factor analysis.

RESULTS

Our results indicated that each measure evaluated herein worked equally well for Hispanic and Caucasian youth. We found measurement invariance at every level tested.

CONCLUSIONS

This study supports the validity and future use of these important and widely-used alcohol use measures for high-risk substance-using Hispanic youth. Further, given the representativeness of this sample within the southwestern U.S., these results show promise for generalizability to U.S.-born Hispanic youth within this geographic region.

Unnecessary Dieting Intention and Behavior among Female Students in Naha City, Japan

Weight concerns and dieting are prevalent among female adolescents both in Western and Asian countries. They can result in negative psychological and physiological consequences. This study aimed to examine the relative importance of social and personal factors in the decision to diet among female adolescent students in Japan, applying the Theory of Planned Behavior. Data were collected from five junior high schools and three high schools in Naha City, Okinawa Prefecture, in 2010, through self-administered questionnaires. The data of 756 female students were assessed. The independent variables included social factor variables (norms) and personal factor variables (attitude to dieting, perceived behavior control, body esteem, body-figure discrepancy and past dieting). The dependent variables were dieting intention and behavior. Hierarchical multiple regression analyses were performed to examine three models: model 1 (age and obesity index), model 2 (social factor variables with age and obesity index) and model 3 (all variables). Although model 2 failed to explain a substantial proportion of the variance, model 3 explained approximately a half of the variance for intention (R² = 0.507) and more than one third of the variance for behavior (R² = 0.376). Past experience of dieting was the best predictor of both dieting intention and behavior. Body esteem was the second best predictor for dieting behavior. In conclusion, personal factors are more likely than social factors to drive the dieting decision. Diet education programs should consider targeting frequent dieters and those with poor body esteem.

Addressing sexual health behaviour during emerging adulthood: a critical review of the literature

AIMS AND OBJECTIVES

In this critical literature review, we examine evidence-based interventions that target sexual behaviours of 18- to 25-year-old emerging adult women.

BACKGROUND

Nurses and clinicians implement theory-driven research programmes for young women with increased risk of HIV/AIDS and sexually transmitted infections. Strategies to decrease transmission of HIV and sexually transmitted infections are rigorously evaluated and promoted by public health agencies such as the United States Centers for Disease Control and Prevention. While many interventions demonstrate episodic reductions in sexual risk behaviours and infection transmission, there is little evidence they build sustainable skills and behaviours. Programmes may not attend to contextual and affective influences on sexual behaviour change.

DESIGN

Discursive paper.

METHODS

We conducted a conceptually based literature review and critical analysis of the Centers for Disease Control and Prevention's best-evidence and good-evidence HIV behavioural interventions. In this review, we examined three contextual and affective influences on the sexual health of emerging adult women: (1) developmental age, (2) reproduction and pregnancy desires and (3) sexual security or emotional responses accompanying relationship experiences.

RESULTS

Our analyses revealed intervention programmes paid little attention to ways age, desires for pregnancy or emotional factors influence sexual decisions. Some programmes included 18- to 25-year-olds, but they made up small percentages of the sample and did not attend to unique emerging adult experiences. Second, primary focus on infection prevention overshadowed participant desires for pregnancy. Third, few interventions considered emotional mechanisms derived from relationship experiences involved in sexual decision-making.

CONCLUSIONS

Growing evidence demonstrates sexual health interventions may be more effective if augmented to attend to contextual and affective influences on relationship risks and decision-making. Modifying currently accepted strategies may enhance sustainability of sexual health-promoting behaviours.

RELEVANCE TO CLINICAL PRACTICE

This study provides nurses and public health educators with recommendations for broadening the content of sexual health promotion intervention programming.

Integrating brain and behavior: evaluating adolescents' response to a cannabis intervention

Client language (change talk [CT] and counterchange talk [CCT]) is gaining increasing support as an active ingredient of psychosocial interventions. Preliminary work with adults suggests that there may be a neural basis for this. With a diverse sample of adolescent cannabis users, we evaluated the influence of CT and CCT on blood oxygen level dependent (BOLD) response during an fMRI cannabis cue-exposure paradigm. We also investigated how BOLD activation related to treatment outcomes. Adolescent cannabis users (N = 43; 83.7% male; 53.5% Hispanic; M age = 16 years) were presented with CT and CCT derived from their prescan intervention session during the fMRI paradigm. Additionally, BOLD activation during CT (vs. CCT) was tested as a predictor of 1-month follow-up cannabis use behavior (frequency of cannabis use, cannabis problems, cannabis dependence). We observed a significant interaction, with greater activation during CT (vs. CCT) during the cannabis (but not control) cues in several areas key to self-referential processes (uncorrected p < 0.001; medial frontal gyrus, insula). Furthermore, BOLD activation during CT (vs. CCT) during cannabis (but not control) cues in areas that underlie introspection (posterior cingulate, precuneus) was significantly related to youths' 1-month follow-up cannabis use behavior (frequency of cannabis use, cannabis problems, cannabis dependence; uncorrected p < 0.001). These data indicate a unique interaction pattern, whereby CT (vs. CCT) during the cannabis (but not control) cues was associated with significantly greater activation in brain areas involved in introspection. Further, this activation was related to significantly better treatment outcomes for youth.

Interventions for encouraging sexual behaviours intended to prevent cervical cancer

BACKGROUND

Human papillomavirus (HPV) is the key risk factor for cervical cancer. Continuing high rates of HPV and other sexually transmitted infections (STIs) in young people demonstrate the need for effective behavioural interventions.

OBJECTIVES

To assess the effectiveness of behavioural interventions for young women to encourage safer sexual behaviours to prevent transmission of STIs (including HPV) and cervical cancer.

SEARCH STRATEGY

Systematic literature searches were performed on the following databases: Cochrane Central Register of Controlled Trials (CENTRAL Issue 4, 2009) Cochrane Gynaecological Cancer Review Group (CGCRG) Specialised Register, MEDLINE, EMBASE, CINAHL, PsychINFO, Social Science Citation Index and Trials Register of Promoting Health Interventions (TRoPHI) up to the end of 2009. All references were screened for inclusion against selection criteria.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of behavioural interventions for young women up to the age of 25 years that included, amongst other things, information provision about the transmission and prevention of STIs. Trials had to measure behavioural outcomes (e.g. condom use) and/or biological outcomes (e.g. incidence of STIs, cervical cancer).

DATA COLLECTION AND ANALYSIS

A narrative synthesis was conducted. Meta-analysis was not considered appropriate due to heterogeneity between the interventions and trial populations.

MAIN RESULTS

A total of 5271 references were screened and of these 23 RCTs met the inclusion criteria. Most were conducted in the USA and in health-care clinics (e.g. family planning).The majority of interventions provided information about STIs and taught safer sex skills (e.g. communication), occasionally supplemented with provision of resources (e.g. free sexual health services). They were heterogeneous in duration, contact time, provider, behavioural aims and outcomes. A variety of STIs were addressed including HIV and chlamydia. None of the trials explicitly mentioned HPV or cervical cancer prevention.Statistically significant effects for behavioural outcomes (e.g. increasing condom use) were common, though not universal and varied according to the type of outcome. There were no statistically significant effects of abstaining from or reducing sexual activity. There were few statistically significant effects on biological (STI) outcomes. Considerable uncertainty exists in the risk of bias due to incomplete or ambiguous reporting.

AUTHORS' CONCLUSIONS

Behavioural interventions for young women which aim to promote sexual behaviours protective of STI transmission can be effective, primarily at encouraging condom use. Future evaluations should include a greater focus on HPV and its link to cervical cancer, with long-term follow-up to assess impact on behaviour change, rates of HPV infection and progression to cervical cancer. Studies should use an RCT design where possible with integral process evaluation and cost-effectiveness analysis where appropriate. Given the predominance of USA studies in this systematic review evaluations conducted in other countries would be particularly useful.

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.e. under testing) interventions is well poised to correct the higher prevalence and incidence among males (vs. females) and African-Americans and Latinos (vs. other groups), but ill poised to correct the higher prevalence and incidence among younger (vs. older) people, as well as men who have sex with men, injection-drug users, and multiple partner heterosexuals (vs. other behavioral groups). Importantly, when the characteristics of the interventions most efficacious for each population were included in the analyses of behavior change, results replicated with three exceptions. Specifically, after accounting for interactions of intervention and facilitator features with characteristics of the recipient population (e.g. gender), there was no behavior change bias for men who have sex with men, younger individuals changed their behavior more than older individuals, and African-Americans changed their behavior less than other groups.

What makes group MET work? A randomized controlled trial of college student drinkers in mandated alcohol diversion

Nationally, college drinkers exhibit the highest rates of alcohol consumption and represent the largest percentage of problem drinkers. Group motivational enhancement therapy (GMET) has been found to catalyze problem drinking reductions among college student samples. Although research supporting the use of single-session GMET in college samples (general and mandated) is emergent, no studies have evaluated a comprehensive model of the potential active ingredients of this group intervention. College students (N = 206; 88% White; 63% men; M age = 18.6) mandated to a university alcohol diversion program were randomly assigned to 1 of 3 conditions: the standard-of-care 2-session "Focus on Alcohol Concerns" education group (FAC), a single GMET, or a single alcohol information-only control group (AI) to evaluate the role of 5 putative mediators: readiness to change, self-efficacy, perceived risk, norm estimates, and positive drinking expectancies. At 3- and 6-month follow-ups, GMET students demonstrated greater reductions in problem drinking outcomes (drinks per drinking day, hazardous drinking symptoms, and alcohol-related problems). Of the 5 mediators proposed, only self-efficacy emerged as a significant mediator.

A systematic review of randomised controlled trials of interventions promoting effective condom use

Background

Effective condom use can prevent sexually transmitted infections (STIs) and unwanted pregnancy. We conducted a systematic review and methodological appraisal of randomised controlled trials (RCTs) of interventions to promote effective condom use.

Methods

We searched for all RCTs of interventions to promote effective condom use using the Cochrane Infectious Diseases Group's trials register (Oct 2006), CENTRAL (Issue 4, 2006), MEDLINE (1966 to Oct 2006), EMBASE (1974 to Oct 2006), LILACS (1982 to Oct 2006), IBSS (1951 to Oct 2006) and Psychinfo (1996 to Oct 2006). We extracted data on allocation sequence, allocation concealment, blinding, loss to follow-up and measures of effect. Effect estimates were calculated.

Results

We identified 139 trials. Seven out of ten trials reported reductions in ‘any STI’ with five statistically significant results. Three out of four trials reported reductions in pregnancy, although none was statistically significant. Only four trials met all the quality criteria. Trials reported a median of 11 (IQR 7–17) outcome measures. Few trials used the same outcome measure. Altogether, 10 trials (7%) used the outcome ‘any STI’, 4 (3%) self-reported pregnancy and 22 (16%) used ‘condom use at last sex’.

Conclusions

The results are generally consistent with modest benefits but there is considerable potential for bias due to poor trial quality. Because of the low proportion of trials using the same outcome the potential for bias from selective reporting of outcomes is considerable. Despite the public health importance of increasing condom use there is little reliable evidence on the effectiveness of condom promotion interventions.

Condom use among high-risk adolescents: testing the influence of alcohol use on the relationship of cognitive correlates of behavior

The goal of this study was the exploration of distal effects of alcohol use on condom use. Criminally involved adolescents completed an initial measure of attitudes, beliefs, and prior behavior. Of the 300 who completed the initial measurement, 267 (89%) completed a behavioral assessment 6 months later. Analyses validated a theoretical model of condom use intentions and indicated that intentions and attitudes measured at baseline were significant predictors of condom use behavior 6 months later. Neither alcohol use nor alcohol problems moderated relationships among model variables or the influence of intentions and attitudes on behavior. The findings do not support a distal role for alcohol use in altering the cognitive correlates of condom use intentions and behavior among high-risk adolescents.

Methodological challenges in research on sexual risk behavior: I. Item content, scaling, and data analytical options

Investigation of sexual behavior involves many challenges, including how to assess sexual behavior and how to analyze the resulting data. Sexual behavior can be assessed using absolute frequency measures (also known as counts) or with relative frequency measures (e.g., rating scales that range from never to always). We discuss these 2 assessment approaches in the context of research on HIV risk behavior. We conclude that these 2 approaches yield nonredundant information and, more important, that only data yielding information about the absolute frequency of risk behavior have the potential to serve as valid indicators of HIV contraction risk. However, analyses of count data may be challenging because of non-normal distributions with many outliers. Therefore, we identify new and powerful data analytical solutions that have been developed recently to analyze count data and discuss limitations of a commonly applied method (viz., analysis of covariance using baseline scores as covariates).
