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

A Content Analysis of Online Messages about Sugar-Sweetened Beverages

Media campaigns can reduce or promote the consumption of sugar-sweetened beverages (SSBs). Brief, US-based English-language online messages were gathered from searchable media platforms, a process that yielded 112 anti-SSB videos and 29 pro-SSB commercials. Using a combination of inductive and deductive methods, a content analysis of those messages was conducted to identify their properties. They were coded for the direction (pro vs. anti), target of the advocacy (e.g., consumption vs. policy), actor demographics (gender, age, and ethnicity), persuasive theme (e.g., excessive sugar, nurturing), and message sensation value. Anti-SSB appeals primarily targeted individual-level consumption behavior. They utilized six persuasive themes and often included more than one theme in a single message. Pro-SSB messages used feel-good themes and utilized only one theme per message. The proportions of adults, adolescents, and children differed by the direction of the advocacy. Black, Hispanic, and Asian actors were under-represented in the anti-SSB sample relative to Whites. Pro-SSB appeals were slightly higher than anti-SSB appeals in message sensation value (p = 0.09). The findings illuminate the message features that characterize the universe of brief anti-SSB appeals available online, highlight messaging disparities, and reveal the absence of certain common, effective persuasive themes.

Encouraging pro-environmental behavior: Do testimonials by experts work?

Using non-pecuniary interventions to motivate pro-environmental behavior appeals to program administrators seeking cost-effective ways to increase adoption of environmental practices. However, all good-intended interventions should not be expected to be effective and reporting when interventions fail is as important as documenting their successes. We used a framed field experiment with 308 adults from the Mid-Atlantic in the United States to test the effectiveness of an expert testimonial in encouraging adoption of native plants in residential settings. Though studies have found testimonials to be effective in other contexts, we find that the video testimonial had no effect on residents' willingness to pay for native plants. Our analysis also shows that consumers who are younger, have higher incomes, and use other environmentally friendly practices on their lawns are more likely than other consumers to purchase native plants.

Enhancing the Cardiovascular Safety of Hemodialysis Care Using Multimodal Provider Education and Patient Activation Interventions: Protocol for a Cluster Randomized Controlled Trial

BACKGROUND

End-stage kidney disease (ESKD) is treated with dialysis or kidney transplantation, with most patients with ESKD receiving in-center hemodialysis treatment. This life-saving treatment can result in cardiovascular and hemodynamic instability, with the most common form being low blood pressure during the dialysis treatment (intradialytic hypotension [IDH]). IDH is a complication of hemodialysis that can involve symptoms such as fatigue, nausea, cramping, and loss of consciousness. IDH increases risks of cardiovascular disease and ultimately hospitalizations and mortality. Provider-level and patient-level decisions influence the occurrence of IDH; thus, IDH may be preventable in routine hemodialysis care.

OBJECTIVE

This study aims to evaluate the independent and comparative effectiveness of 2 interventions-one directed at hemodialysis providers and another for patients-in reducing the rate of IDH at hemodialysis facilities. In addition, the study will assess the effects of interventions on secondary patient-centered clinical outcomes and examine factors associated with a successful implementation of the interventions.

METHODS

This study is a pragmatic, cluster randomized trial to be conducted in 20 hemodialysis facilities in the United States. Hemodialysis facilities will be randomized using a 2 × 2 factorial design, such that 5 sites will receive a multimodal provider education intervention, 5 sites will receive a patient activation intervention, 5 sites will receive both interventions, and 5 sites will receive none of the 2 interventions. The multimodal provider education intervention involved theory-informed team training and the use of a digital, tablet-based checklist to heighten attention to patient clinical factors associated with increased IDH risk. The patient activation intervention involves tablet-based, theory-informed patient education and peer mentoring. Patient outcomes will be monitored during a 12-week baseline period, followed by a 24-week intervention period and a 12-week postintervention follow-up period. The primary outcome of the study is the proportion of treatments with IDH, which will be aggregated at the facility level. Secondary outcomes include patient symptoms, fluid adherence, hemodialysis adherence, quality of life, hospitalizations, and mortality.

RESULTS

This study is funded by the Patient-Centered Outcomes Research Institute and approved by the University of Michigan Medical School's institutional review board. The study began enrolling patients in January 2023. Initial feasibility data will be available in May 2023. Data collection will conclude in November 2024.

CONCLUSIONS

The effects of provider and patient education on reducing the proportion of sessions with IDH and improving other patient-centered clinical outcomes will be evaluated, and the findings will be used to inform further improvements in patient care. Improving the stability of hemodialysis sessions is a critical concern for clinicians and patients with ESKD; the interventions targeted to providers and patients are predicted to lead to improvements in patient health and quality of life.

Social-contextual factors interact with masculinity to influence college men's HPV vaccination intentions: The role of descriptive norms, prototypes, and physician gender

Men’s low HPV vaccination uptake and HPV-related disease incidence are public health issues; gendered social–contextual factors likely play a role. In Study 1, college men (N = 130; M_age = 19.55; white = 58.1%) reported their social cognitions (male-referent descriptive norms and prototypes), self-reliance masculinity ideology, and vaccination intentions. In Study 2, college men (N = 106; M_age = 19.32; white = 61.3%) were randomly assigned to receive HPV vaccination information from a man or woman physician-avatar. Descriptive norms and favorable prototypes (bs ≥ .337; ps ≤ .016) were associated with higher HPV vaccination intentions. Men with higher self-reliance masculinity had higher HPV vaccination intentions with a man physician and when they perceived greater vaccination among men (ps ≤ .035). Men with higher self-reliance masculinity are more sensitive to gendered social–contextual effects in HPV vaccination decision-making. Gendered social–contextual factors should be integrated into public health interventions to increase college men’s HPV vaccination uptake.

Effects of a Sexual Risk-Reduction Intervention for Teenagers: A Cluster-Randomized Control Trial

This study evaluated the efficacy of the COMPAS program in the short term and 6 months after its application. For the initial sample, 2047 teenagers aged 14–19 years from 14 schools in 11 Colombian cities participated; eight schools were randomly assigned to the experimental condition and six to the control group. The participants completed self-report assessments that evaluated several variables theoretically associated with protective sexual behaviors. In the short term, the experimental group showed increased knowledge about HIV and other STIs, sexual assertiveness, self-efficacy, greater behavioral intention toward condom use, and more favorable attitudes toward HIV and condom use than the control group. After 6 months, most psychological and health variables also showed a significant positive change. In conclusion, the COMPAS program is the first school-based sexuality education program that has been shown to be effective in reducing mediating and behavioral variables associated with sexual risk reduction in Colombia.

Facing Our Fears: The Impact of a 4-Day Training Intervention to Reduce Negative Perspectives on Sexual and Gender Minorities among Religious Leaders in Kenya

This study evaluated short- and long-term impact of a 4-day training intervention to reduce negative perspectives of religious leaders in Kenya on sexual and gender minorities, adopting a one-group pretest-posttest-follow-up design. Religious leaders' perspectives play an important role in maintaining the negative status quo for sexual and gender minorities, especially in Africa, where religion's impact is ubiquitous and holding negative attitudes against these populations is perceived as an expression of doctrinal orthodoxy. The training, developed by a community-based organization, employs a variety of strategies, including education, storytelling, and in-person contact. Data were collected directly before and after the training, and at 3- to 4-months follow-up. After the training, acceptance of lesbian women and gay men and gender diversity had increased, while attitudes toward gender and sexual minorities became more positive. Interaction effect analysis showed that compared to women, men changed more, as did those who scored higher on religious fundamentalism. Changes in attitudes were maintained at follow-up (three to four months). Although it is not clear whether the training had an impact on the religious leaders' interactions with members of their congregation, these findings suggest that intensive trainings may promote positive changes in their perspective on gender and sexual minorities.

Using the participatory education and research into lived experience (PEARLE) methodology to localize content and target specific populations

Technology-based behavioral health interventions offer potentially limitless opportunities to localize content and target specific populations. However, this ability to customize requires developers to make a wide range of decisions not only about who should appear on screen, but how each message should be refined to most effectively reach a particular group of intervention recipients. These issues become especially salient as interventions are scaled for delivery to multiple populations in different geographical locations or settings (e.g., a hospital emergency department versus the drop-in center of a community-based clinic), and in more than one language. To facilitate evidence-based development of customized, targeted intervention content, our team created a multi-step methodology over a series of NIH-funded research projects. The resulting Participatory Education and Research into Lived Experience (PEARLE) Methodology entails formative qualitative interviews to examine why members of a given population do not enact a specific health behavior such as HIV/HCV testing or vaccinating against COVID-19 (this step includes identifying potential gaps in related health literacy), followed by iterative evaluations of draft content designed to address these barriers, and extensive discussions with a Community Advisory Board. The final step is a clinical trial. PEARLE is designed to be highly flexible, adaptable to a variety of behavioral outcomes in clinical and community settings, and to create content in more than one language depending on the needs or preferences of a population. The current paper discusses how our team employed PEARLE to develop content in English and Spanish for our latest project, which is intended to increase COVID-19 vaccination uptake among people who inject drugs.

The importance of content and choice in a technology-based intervention to increase HIV testing

Although the Centers for Disease Control and Prevention recommends routine HIV testing in emergency departments and other facilities, many patients are never offered testing, and those who are offered testing frequently decline. In response, our team developed and evaluated a series of differently configured technology-based interventions to explore how we can most effectively increase HIV testing among reluctant patients. The current study examines how different videos (onscreen physician vs. onscreen community member), and different intervention configurations (enabling some participants to select a video while others are assigned to watch a video or to view bullet-point text), could potentially increase self-efficacy to test for HIV among patients who had never tested. Analyses of data from 285 emergency department patients in New York City who declined HIV testing offered by hospital staff indicated that participants reported highly significant differences in self-efficacy depending on their history of previous testing, whether they were enabled to select a video or were assigned a video, and which video they watched. Participants who reported no previous testing reported significantly lower pre-test self-efficacy compared to those who had tested at least once before. Among those who had not previously tested, the greatest pre-post increases in self-efficacy were reported by participants who were randomly enabled to select an intervention video and chose to watch video depicting a physician. Our findings highlight the importance, not only of intervention content, but how that content is delivered to specific participants. These findings may inform more effective technology-based behavioral health interventions.

Can you believe it? An investigation into the impact of retraction source credibility on the continued influence effect

The continued influence effect refers to the finding that people often continue to rely on misinformation in their reasoning even if the information has been retracted. The present study aimed to investigate the extent to which the effectiveness of a retraction is determined by its credibility. In particular, we aimed to scrutinize previous findings suggesting that perceived trustworthiness but not perceived expertise of the retraction source determines a retraction's effectiveness, and that continued influence arises only if a retraction is not believed. In two experiments, we found that source trustworthiness but not source expertise indeed influences retraction effectiveness, with retractions from low-trustworthiness sources entirely ineffective. We also found that retraction belief is indeed a predictor of continued reliance on misinformation, but that substantial continued influence effects can still occur with retractions designed to be and rated as highly credible.

More behavioral recommendations produce more change: A meta-analysis of efficacy of multibehavior recommendations to reduce nonmedical substance use

Death and morbidity associated with substance use have risen continuously over the last few decades, increasing the need for rigorous examination of promising programs. Interventions attempting to change multiple behaviors have been designed to address interconnected problems such as use of both alcohol and drugs. This meta-analysis aimed to examine the efficacy of multibehavior interventions to curb nonmedical substance use in relation to the theoretical relation among different substance use behaviors. Specifically, our synthesis aimed to estimate the optimal number of recommendations for intervention efficacy and evaluate the impact of different combinations of recommendations on intervention efficacy. A synthesis of multibehavior interventions addressing nonmedical substance use was conducted to measure behavioral changes between the pretest and the follow-up. These changes were then compared across different numbers of recommendations. Sixty-nine reports and 233 effect sizes (k of conditions = 155, n = 28,295) were included. A positive linear relation was found between the number of targeted behaviors and intervention efficacy, which was stronger for drug use than alcohol use. Furthermore, recommendations on drug use worked better when paired with recommendations targeting other behaviors, whereas recommendations on alcohol use worked more independently. Lastly, multibehavior interventions were especially efficacious when delivered by experts. Overall, our synthesis indicated that targeting multiple substances is beneficial for changing drug use outcomes, but less so for alcohol use outcomes. Therefore, in the current substance use epidemic, innovative multibehavior programs appear to hold promise, especially to combat nonmedical drug use.

Communication-Based Approach for Promoting Energy Consumer Switching: Some Evidence from Ofgem’s Database Trials in the United Kingdom

Prompted by rising concern about weak consumer switching and the practice of price discrimination, over the period of 2016–2019, the Office of Gas and Electricity Markets (Ofgem) undertook a series of trials on communication-based interventions to encourage consumer switching in the United Kingdom. The main purpose of this paper is to assess the experience of these Ofgem trials with a view to draw some lessons for policy makers. The analytical framework adopted for this purpose is informed by existing literature on the barriers for consumer switching. The results of the analysis suggest that while the Ofgem trials have made positive impacts on consumer switching, these impacts varied significantly across the trials, suggesting that some interventions were more effective than others. Further, the overall impacts of the Ofgem trials were moderate, as around 70% of participants did not switch suppliers even in the most impactful trial. This reflects a general lack of understanding in the literature about the behaviour-influencing factors, their impacts, and their context-connects. By implication, the difficulty in stimulating consumer switching, as demonstrated by the Ofgem trials, suggests that weak consumer switching and the practice of price discrimination may simply reflect significant competition, rather than a lack of it, especially if retail margins are not greater than the competitive level. In this case, the communication-based intervention aimed at encouraging consumer switching may lead to further price discrimination, especially for the most vulnerable consumers, who are more likely to stay with their incumbent suppliers.

The effects of source expertise and trustworthiness on recollection: the case of vaccine misinformation

Designing effective communication strategies for correcting vaccines misinformation requires an understanding of how the target group might react to information from different sources. The present study examined whether erroneous inferences about vaccination could be effectively corrected by a perceived credible (i.e. expert or trustworthy) source. Two experiments are reported using a standard continued influence paradigm, each featuring two correction conditions on vaccine misinformation. Participants were presented with a story containing a piece of information that was later retracted by a perceived credible or not so credible source. Experiment 1 showed that providing a correction reduced participants' use of the original erroneous information, yet the overall reliance on misinformation did not significantly differ between the low- and high-expertise correction groups. Experiment 2 revealed that a correction from a high-trustworthy source decreased participants' reliance on misinformation when making inferences; nonetheless, it did not positively affect the reported intent to vaccinate one's child. Overall, source trustworthiness was more relevant than source expertise.

Socio-Economic Effect on ICT-Based Persuasive Interventions Towards Energy Efficiency in Tertiary Buildings

Occupants of tertiary environments rarely care about their energy consumption. This fact is even more accentuated in cases of buildings of public use. Such unawareness has been identified by many scholars as one of the main untapped opportunities with high energy saving potential in terms of cost-effectiveness. Towards that direction, there have been numerous studies exploring energy-related behaviour and the impact that our daily actions have on energy efficiency, demand response and flexibility of power systems. Nevertheless, there are still certain aspects that remain controversial and unidentified, especially in terms of socio-economic characteristics of the occupants with regards to bespoke tailored motivational and awareness-based campaigns. The presented work introduces a two-step survey, publicly available through Zenodo repository that covers social, economic, behavioural and demographic factors. The survey analysis aims to fully depict the drivers that affect occupant energy-related behaviour at tertiary buildings and the barriers which may hinder green actions. Moreover, the survey reports evidence on respondents’ self-assessment of fifteen known principles of persuasion intended to motivate them to behave pro-environmentally. The outcomes from the self-assessment help to shed light on understanding which of the Persuasive Principles may work better to nudge different user profiles towards doing greener actions at workplace. This study was conducted in four EU countries, six different cities and seven buildings, reaching more than three-hundred-and-fifty people. Specifically, a questionnaire was delivered before (PRE) and after (POST) a recommendation-based intervention towards pro-environmental behaviour through Information and Communication Technologies (ICT). The findings from the PRE-pilot stage were used to refine the POST-pilot survey (e.g., we removed some questions that did not add value to one or several research questions or dismissed the assessment of Persuasive Principles (PPs) which were of low value to respondents in the pre-pilot survey). Both surveys validate “Cause and Effect”, “Conditioning” and “Self-monitoring” as the top PPs for affecting energy-related behaviour in a workplace context. Among other results, the descriptive and prescriptive analysis reveals the association effects of specific barriers, pro-environmental intentions and confidence in technology on forming new pro-environmental behaviour. The results of this study intend to set the foundations for future interventions based on persuasion through ICT to reduce unnecessary energy consumption. Among all types of tertiary buildings, we emphasise on the validity of the results provided for buildings of public use.

Utilization of an Animated Electronic Health Video to Increase Knowledge of Post- and Pre-Exposure Prophylaxis for HIV Among African American Women: Nationwide Cross-Sectional Survey

Background

Despite renewed focus on biomedical prevention strategies since the publication of several clinical trials highlighting the efficacy of pre-exposure prophylaxis (PrEP), knowledge of postexposure prophylaxis (PEP) and PrEP continues to remain scarce among women, especially among African American women who are disproportionally affected by HIV. In an effort to address this barrier and encourage uptake of PEP and PrEP, an electronic health (eHealth) video was created using an entertainment-education format.

Objective

The study aimed to explore the feasibility, acceptability, and preference of an avatar-led, eHealth video, PEP and PrEP for Women, to increase awareness and knowledge of PEP and PrEP for HIV in a sample of African American women.

Methods

A cross-sectional, Web-based study was conducted with 116 African American women aged 18 to 61 years to measure participants’ perceived acceptability of the video on a 5-point scale: poor, fair, good, very good, and excellent. Backward stepwise regression was used to the find the outcome variable of a higher rating of the PEP and PrEP for Women video. Thematic analysis was conducted to explore the reasons for recommending the video to others after watching the eHealth video.

Results

Overall, 89% of the participants rated the video as good or higher. A higher rating of the educational video was significantly predicted by: no current use of drugs/alcohol (beta=−.814; P=.004), not having unprotected sex in the last 3 months (beta=−.488; P=.03), higher income (beta=.149; P=.03), lower level of education (beta=−.267; P=.005), and lower exposure to sexual assault since the age of 18 years (beta=−.313; P=.004). After watching the eHealth video, reasons for recommending the video included the video being educational, entertaining, and suitable for women.

Conclusions

Utilization of an avatar-led eHealth video fostered education about PEP and PrEP among African American women who have experienced insufficient outreach for biomedical HIV strategies. This approach can be leveraged to increase awareness and usage among African American women.

Influences on safety consciousness in a utility company: A sequential mediation model

INTRODUCTION

The purpose of this research was to determine whether the influence of supervisory support for safety on safety consciousness is direct or indirect. Based in part on predictions from the Theory of Reasoned Action (TRA) and Social Cognitive Theory (SCT), we examined the extent to which belief (safety self-efficacy) and attitude (cavalier safety attitude) mediate the impact of supervisory support for safety on employee safety consciousness.

METHOD

A survey of 995 employees was distributed across 24 work groups in an electric utility company, and sequential mediation modeling was used to determine indirect effects on safety consciousness.

RESULTS

We found that the effect of supervisory support on safety consciousness was indirect, fully mediated through both efficacy and attitude in a sequential mediation model. Practical applications: Supervisors should be aware of and emphasize supportive behaviors and create welcoming conditions for employees to raise safety concerns. Furthermore, organizational programs pertaining to safety improvement need to consider how to develop positive beliefs regarding safety activity and attitudes and reduce negative ones.

Systematically Developing a Web-Based Tailored Intervention Promoting HPV-Vaccination Acceptability Among Mothers of Invited Girls Using Intervention Mapping

Background: Currently, the eHealth field calls for detailed descriptions of theory-based interventions in order to support improved design of such interventions. This article aims to provide a systematic description of the design rationale behind an interactive web-based tailored intervention promoting HPV-vaccination acceptability.

Methods: The 6-step Intervention Mapping (IM) protocol was used to describe the design rationale. After the needs assessment in Step 1, intervention objectives were formulated in Step 2. In Step 3, we translated theoretical methods into practical applications, which were integrated into a coherent intervention in Step 4. In Step 5, we anticipated future implementation and adoption, and finally, an evaluation plan was generated in Step 6.

Results: Walking through the various steps of IM resulted in a detailed description of the intervention. The needs assessment indicated HPV-vaccination uptake remaining lower than expected. Mothers play the most important role in decision-making about their daughter's immunization. However, they generally feel ambivalent after they made their decisions, and their decisions are based on rather unstable grounds. Therefore, intervention objectives were to improve HPV-vaccination uptake and informed decision-making, and to decrease decisional conflict among mothers of invited girls. Computer-tailoring was chosen as the main method; virtual assistants were chosen as a practical application to deliver interactive tailored feedback. To maximize compatibility with the needs of the target group, a user-centered design strategy by means of focus groups and online experiments was applied. In these, prototypes were tested and sequentially refined. Finally, efficacy, effectiveness, and acceptability of the intervention were tested in a randomized controlled trial. Results showed a significant positive effect of the intervention on informed decision-making, decisional conflict, and nearly all determinants of HPV-vaccination uptake (P < 0.001). Mothers evaluated the intervention as highly positive.

Discussion: Using IM led to an innovative effective intervention for promoting HPV-vaccination acceptability. The intervention maps will aid in interpreting the results of our evaluation studies. Moreover, it will ease the comparison of design rationales across interventions, and may provide leads for the development of other eHealth interventions. This paper adds to the plea for systematic reporting of design rationales constituting the process of developing interventions.

Interventions to reduce risk for sexually transmitted infections in adolescents: A meta-analysis of trials, 2008-2016

BACKGROUND

Numerous studies have evaluated the efficacy of interventions to reduce risk for sexually transmitted infections in adolescents in recent years, but their global effects remain unknown since 2008, the last date of a comprehensive review of prior studies.

AIMS

This study aims at evaluating the efficacy of interventions to promote sexual health, reduce STIs and unplanned pregnancies targeted to adolescents available after 2008; and analyzing the moderators of their global efficacy.

METHODS

We searched electronic databases and manual searches of some journals focused on STIs in May 2016. The studies evaluated the efficacy of interventions to reduce sexual risk in adolescents (age range: 11-19) anywhere in the world. Effect size of the relevant outcomes for sexual risk was calculated for every study. Analyses incorporated random-effect assumptions for each outcome. The homogeneity in the results was examined with the I2 statistic and its associated 95% confident interval.

RESULTS

Data from 63 studies (59,795 participants) were analyzed for behavioral and non-behavioral outcomes. In the short term, interventions had a positive impact in sexual health-related knowledge (Hedges'g = 1.01), attitudes (g = 0.29), self-efficacy toward condom use (g = 0.22), intention to refuse sex (g = 0.56), condom use intention (g = 0.46), and condom use (g = 0.38). In the medium term, positive effects observed at the short-term were maintained, although effect size significantly decreased in all variables. In the long term, interventions improved condom use (g = 0.47). Moderators of the efficacy are discussed.

CONCLUSIONS

Sexual health promotion interventions are effective to promote sexual health through increasing condom use. Effects on non-behavioral variables tend to decrease over time, while condom use increased in the long-term. Interventions should focus on the long-term efficacy, especially in behavioral and biological measures.

Does Segmentation Really Work? Effectiveness of Matched Graphic Health Warnings on Cigarette Packaging by Race, Gender and Chronic Disease Conditions on Cognitive Outcomes among Vulnerable Populations

We examined the differential impact of exposure to smoking-related graphic health warnings (GHWs) on risk perceptions and intentions to quit among different audience segments characterized by gender, race/ethnic group, and presence of chronic disease condition. Specifically, we sought to test whether GHWs that portray specific groups (in terms of gender, race, and chronic disease conditions) are associated with differences in risk perception and intention to quit among smokers who match the portrayed group. We used data from Project CLEAR, which oversampled lower SES groups as well as race/ethnic minority groups living in the Greater Boston area (n = 565). We fitted multiple linear regression models to examine the impact of exposure to different GHWs on risk perceptions and quit intentions. After controlling for age, gender, education and household income, we found that women who viewed GHWs portraying females reported increased risk perception as compared to women who viewed GHWs portraying men. However, no other interactions were found between the groups depicted in GHWs and audience characteristics. The findings suggest that audience segmentation of GHWs may have limited impact on risk perceptions and intention to quit smoking among adult smokers.

Who is Saying What on Twitter: An Analysis of Messages with References to HIV and HIV Risk Behavior

This research aimed to determine the nature of social media discussions about HIV. With the goal of conducting a descriptive analysis, we collected almost 1,000 tweets posted February to September 2015. The sample of tweets included keywords related to HIV or behavioral risk factors (e.g., sex, drug use) and was coded for content (e.g., HIV), behavior change strategies, and message source. Seven percent of tweets concerned HIV/AIDS, which were often referred to as jokes or insults. The majority of tweets coded as behavior change attempts involved attitude change strategies. The majority of the tweets (80%) came from private users (vs. organizations). Different types of sources employed different types of behavior change strategies: For instance, private users, compared to experts or organizations, included more strategies to decrease detrimental attitudes (29% versus 6%, p < .001), and also more strategies to counter myths and misinformation (6% versus 1%, p = .008). In summary, tweets related to HIV/AIDS and associated risk factors frequently use the terms in jokes and insults, come largely from private users, and entail attitudinal and informational strategies. Online health campaigns with clear calls to action and corrections of misinformation may make important contributions to social media conversations about HIV/AIDS.

Peer-Led or Expert-Led Intervention in HIV Prevention Efficacy? A Randomized Control Trial Among Spanish Young People to Evaluate Their Role

HIV new infections still affect young people around the world. In this context, behavioral interventions seem to be effective in promoting safe sex although some conditions are still inconclusive in different regions. For example, there is insufficient evidence about who may be the best facilitator. For this reason, this study evaluates the effectiveness of peer and expert facilitators for HIV prevention aimed at Spanish young people. For this purpose 225 Spanish college students, aged between 18 and 25 (74.20% women and 25.80% men), were involved in an experimental design to evaluate the facilitators' effect in a brief intervention for HIV prevention. Participants' results were measured by three HIV preventive variables (knowledge, beliefs, and protective sex behavior in vaginal sex, anal sex, and sex after drugs consumption). Our findings reveal that both facilitators, experts and peers, have improved the HIV-associated factors and safe sex behaviors. Therefore, facilitators' status would not be so relevant for effectiveness in HIV prevention aimed at Spanish young people. To facilitate decision making in HIV prevention, we should study in depth what other variables make more effective facilitators.

‘I just want to get on with my life’: a mixed-methods study of active management of quality of life in living with dementia

The active management of the experience of living with dementia appears to improve quality of life despite the lack of disease modification. However, research to date has been largely of modest scale and explanatory factors for improvements have been under-conceptualised. Thus, although promulgated through national strategies, the evidence base is relatively weak. This paper reports on a nation-wide study of the influence of the National Dementia Strategy for England in relation to Dementia Adviser and Peer Support Network services in 40 demonstration sites. The research aimed to identify ways in which the services contribute to the wellbeing and resilience of people with dementia and care partners. A mixed-methods research design collected data through: activity and outcome monitoring; organisational surveys; in-depth case studies, including qualitative interviews with people with dementia (N = 47) and care partners (N = 54), wellbeing and quality of life measures, and interviews with staff and other stakeholders (N = 82). Three themes are explored: addressing individual and community needs; promoting independence, control and choice; and getting a life back. Services promoted independence, control and choice, and consequently enabled people to re-narrate their lives as purposeful within their communities. Ways in which these are achieved resemble the public health model of lay health advisor and this research adds to the imperative to approach dementia as a key public health concern.

Effect of Character-Audience Similarity on the Perceived Effectiveness of Antismoking PSAs via Engagement

This study assesses the impact of character-audience similarity, a core aspect of tailored communication, on evaluation of antismoking public service announcements (PSAs). Smoker and persuader characters are distinguished to explore their different roles in message effectiveness. Daily adult smokers (n = 1,160) were exposed to four video PSAs randomly selected from a larger pool. Similarity scores were determined from matching in demographic (age, gender, race) and motivational factors (quitting status) between the audience and the PSA's characters. Results show that PSAs featuring distinctive smoker and/or persuader characters yielded significantly higher message engagement and perceived effectiveness (PE) than PSAs without characters. Given the presence of characters, smoker-audience similarity was positively associated with the engagement, which in turn enhanced PE. Persuader-audience similarity failed to predict increases in either engagement or PE.

Reliability of Identification of Behavior Change Techniques in Intervention Descriptions

PURPOSE

The aim of this paper is to assess the frequency of identification as well as the inter-coder and test-retest reliability of identification of behavior change techniques (BCTs) in written intervention descriptions.

METHODS

Forty trained coders applied the "Behavior Change Technique Taxonomy version 1" (BCTTv1) to 40 intervention descriptions published in protocols and repeated this 1 month later.

RESULTS

Eighty of 93 defined BCTs were identified by at least one trained coder, and 22 BCTs were identified in 16 (40 %) or more of 40 descriptions. Good inter-coder reliability was observed across 80 BCTs identified in the protocols: 66 (80 %) achieved mean prevalence and bias-adjusted kappa (PABAK) scores of 0.70 or greater, and 59 (74 %) achieved mean scores of 0.80 or greater. There was good within-coder agreement between baseline and 1 month, demonstrating good test-retest reliability.

CONCLUSIONS

BCTTv1 can be used by trained coders to identify BCTs in intervention descriptions reliably. However, some frequently occurring BCT definitions require further clarification.

Ability of HIV Advocacy to Modify Behavioral Norms and Treatment Impact: A Systematic Review

BACKGROUND

HIV advocacy programs are partly responsible for the global community's success in reducing the burden of HIV. The rising wave of the global burden of noncommunicable diseases (NCDs) has prompted the World Health Organization to espouse NCD advocacy efforts as a possible preventive strategy. HIV and NCDs share some similarities in their chronicity and risky behaviors, which are their associated etiology. Therefore, pooled evidence on the effectiveness of HIV advocacy programs and ideas shared could be replicated and applied during the conceptualization of NCD advocacy programs. Such evidence, however, has not been systematically reviewed to address the effectiveness of HIV advocacy programs, particularly programs that aimed at changing public behaviors deemed as risk factors.

OBJECTIVES

To determine the effectiveness of HIV advocacy programs and draw lessons from those that are effective to strengthen future noncommunicable disease advocacy programs.

SEARCH METHODS

We searched for evidence regarding the effectiveness of HIV advocacy programs in medical databases: PubMed, The Cumulative Index to Nursing and Allied Health Literature Plus, Educational Resources and Information Center, and Web of Science, with articles dated from 1994 to 2014. Search criteria. The review protocol was registered before this review. The inclusion criteria were studies on advocacy programs or interventions. We selected studies with the following designs: randomized controlled design studies, pre-post intervention studies, cohorts and other longitudinal studies, quasi-experimental design studies, and cross-sectional studies that reported changes in outcome variables of interest following advocacy programs. We constructed Boolean search terms and used them in PubMed as well as other databases, in line with a population, intervention, comparator, and outcome question. The flow of evidence search and reporting followed the standard Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.

DATA COLLECTION AND ANALYSIS

We selected 2 outcome variables (i.e., changing social norms and a change in impact) out of 6 key outcomes of advocacy interventions. We assessed the risk of bias for all selected studies by using the Cochrane risk-of-bias tool for randomized studies and using the Risk of Bias for Nonrandomized Observational Studies for observational studies. We did not grade the collective quality of evidence because of differences between the studies, with regard to methods, study designs, and context. Moreover, we could not carry out meta-analyses because of heterogeneity and the diverse study designs; thus, we used a narrative synthesis to report the findings.

MAIN RESULTS

A total of 25 studies were eligible, of the 1463 studies retrieved from selected databases. Twenty-two of the studies indicated a shift in social norms as a result of HIV advocacy programs, and 3 indicated a change in impact. We drew 6 lessons from these programs that may be useful for noncommunicable disease advocacy: (1) involving at-risk populations in advocacy programs, (2) working with laypersons and community members, (3) working with peer advocates and activists, (4) targeting specific age groups and asking support from celebrities, (5) targeting several, but specific, risk factors, and (6) using an evidence-based approach through formative research. Author conclusions. HIV advocacy programs have been effective in shifting social norms and facilitating a change in impact.

PUBLIC HEALTH IMPLICATIONS

The lessons learned from these effective programs could be used to improve the design and implementation of future noncommunicable disease advocacy programs.

Behaviour change techniques: the development and evaluation of a taxonomic method for reporting and describing behaviour change interventions (a suite of five studies involving consensus methods, randomised controlled trials and analysis of qualitative data)

BACKGROUND

Meeting global health challenges requires effective behaviour change interventions (BCIs). This depends on advancing the science of behaviour change which, in turn, depends on accurate intervention reporting. Current reporting often lacks detail, preventing accurate replication and implementation. Recent developments have specified intervention content into behaviour change techniques (BCTs) - the 'active ingredients', for example goal-setting, self-monitoring of behaviour. BCTs are 'the smallest components compatible with retaining the postulated active ingredients, i.e. the proposed mechanisms of change. They can be used alone or in combination with other BCTs' (Michie S, Johnston M. Theories and techniques of behaviour change: developing a cumulative science of behaviour change. Health Psychol Rev 2012;6:1-6). Domain-specific taxonomies of BCTs have been developed, for example healthy eating and physical activity, smoking cessation and alcohol consumption. We need to build on these to develop an internationally shared language for specifying and developing interventions. This technology can be used for synthesising evidence, implementing effective interventions and testing theory. It has enormous potential added value for science and global health.

OBJECTIVE

(1) To develop a method of specifying content of BCIs in terms of component BCTs; (2) to lay a foundation for a comprehensive methodology applicable to different types of complex interventions; (3) to develop resources to support application of the taxonomy; and (4) to achieve multidisciplinary and international acceptance for future development.

DESIGN AND PARTICIPANTS

Four hundred participants (systematic reviewers, researchers, practitioners, policy-makers) from 12 countries engaged in investigating, designing and/or delivering BCIs. Development of the taxonomy involved a Delphi procedure, an iterative process of revisions and consultation with 41 international experts; hierarchical structure of the list was developed using inductive 'bottom-up' and theory-driven 'top-down' open-sort procedures (n = 36); training in use of the taxonomy (1-day workshops and distance group tutorials) (n = 161) was evaluated by changes in intercoder reliability and validity (agreement with expert consensus); evaluating the taxonomy for coding interventions was assessed by reliability (intercoder; test-retest) and validity (n = 40 trained coders); and evaluating the taxonomy for writing descriptions was assessed by reliability (intercoder; test-retest) and by experimentally testing its value (n = 190).

RESULTS

Ninety-three distinct, non-overlapping BCTs with clear labels and definitions formed Behaviour Change Technique Taxonomy version 1 (BCTTv1). BCTs clustered into 16 groupings using a 'bottom-up' open-sort procedure; there was overlap between these and groupings produced by a theory-driven, 'top-down' procedure. Both training methods improved validity (both p < 0.05), doubled the proportion of coders achieving competence and improved confidence in identifying BCTs in workshops (both p < 0.001) but did not improve intercoder reliability. Good intercoder reliability was observed for 80 of the 93 BCTs. Good within-coder agreement was observed after 1 month (p < 0.001). Validity was good for 14 of 15 BCTs in the descriptions. The usefulness of BCTTv1 to report descriptions of observed interventions had mixed results.

CONCLUSIONS

The developed taxonomy (BCTTv1) provides a methodology for identifying content of complex BCIs and a foundation for international cross-disciplinary collaboration for developing more effective interventions to improve health. Further work is needed to examine its usefulness for reporting interventions.

A synthesis of meta-analytic evidence of behavioral interventions to reduce HIV/STIs

To identify the mode of delivery, communicator, and content dimensions that make STI/HIV prevention interventions most successful at increasing condom use/protected sex or reducing STI/HIV incidence. A literature search for published meta-analyses of STI/HIV prevention interventions yielded 37 meta-analyses that had statistically tested the moderating effects of the dimensions. Significant and non-significant moderators from the coded dimensions were extracted from each meta-analysis. The most consistently significant moderators included matching the gender or ethnicity of the communicator to the intervention recipients, group targeting or tailoring of the intervention, use of a theory to underpin intervention design, providing factual information, presenting arguments designed to change attitudes, and providing condom skills and intrapersonal skills training. The absence of significant effects for intervention duration and expert delivery are also notable. The success of HIV/STI prevention interventions may be enhanced not only by providing skills training and information designed to change attitudes, but also by ensuring that the content is tailored to the target group and delivered by individuals of the same gender and ethnicity as the recipients.

When it comes to lifestyle recommendations, more is sometimes less: a meta-analysis of theoretical assumptions underlying the effectiveness of interventions promoting multiple behavior domain change

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 curvilinear relation between the number of behavioral recommendations and improvements in behavioral and clinical measures, with a moderate number of recommendations producing the highest level of change. A moderate number of recommendations is likely to be associated with stronger effects because the intervention ensures the necessary level of motivation to implement the recommended changes, thereby increasing compliance with the goals set by the intervention, without making the intervention excessively demanding. Second, this curve was more pronounced when samples were likely to have low motivation to change, such as when interventions were delivered to nonpatient (vs. patient) populations, were implemented in nonclinic (vs. clinic) settings, used lay community (vs. expert) facilitators, and involved group (vs. individual) delivery formats. Finally, change in behavioral outcomes mediated the effects of number of recommended behaviors on clinical change. These findings provide important insights that can help guide the design of effective multiple behavior domain interventions.

Effects of behavioral intervention content on HIV prevention outcomes: a meta-review of meta-analyses

OBJECTIVE

Numerous meta-analyses have examined the success of trials of interventions to reduce the behavioral risk of acquiring or transmitting HIV. Yet, to date, meta-reviews have not systematically examined which type of intervention content is more likely to lead to successful HIV outcomes. The current study addresses this gap.

METHODS

Published meta-analyses on HIV prevention (k = 56) were retrieved, then coded, and analyzed in terms of the intervention content.

RESULTS

Past meta-analyses have examined relatively few dimensions of intervention content. Larger meta-analyses were more likely to find that information content dimensions, especially skill provision and motivational enhancement, relate to risk reduction.

CONCLUSIONS

Fully incorporating behavior change technique (BCT) taxonomies into both intervention research and systematic reviews of this research offers considerable potential. It can improve the precision of conclusions about which specific types of content best promote HIV prevention behaviors and help to lower the cost of interventions. International efforts to improve reporting standards and generate the scholarly expertise necessary to discern BCTs reliably and validly help to address some of the challenges to including BCTs in study reports. Contextualizing research on effective strategies for HIV prevention by reporting and including in analyses community, social, and sample factors is also recommended. Together, such efforts can help refocus the field of HIV prevention on improved research strategies to further improve future interventions by discerning the content design factors related to success for particular populations, rather than merely to assess whether interventions have been successful.

Making and maintaining lifestyle changes with the support of a lay health advisor: longitudinal qualitative study of health trainer services in northern England

Objective

To explore and document the experiences of those receiving support from a lay health trainer, in order to inform the optimisation and evaluation of such interventions.

Design

Longitudinal qualitative study with up to four serial interviews conducted over 12 months. Interviews were transcribed and analysed using the constant comparative approach associated with grounded theory.

Participants

13 health trainers, 5 managers and 26 clients.

Setting

Three health trainer services targeting disadvantaged communities in northern England.

Results

The final dataset comprised 116 interviews (88 with clients and 28 with staff). Discussions with health trainers and managers revealed a high degree of heterogeneity between the local services in terms of their primary aims and activities. However, these were found to converge over time. There was agreement that health trainer interventions are generally ‘person-centred’ in terms of being tailored to the needs of individual clients. This led to a range of self-reported outcomes, including behaviour changes, physical health improvements and increased social activity. Factors impacting on the maintenance of lifestyle changes included the cost and timing of health-promoting activities, ill-health or low mood. Participants perceived a need for ongoing access to low cost facilities to ensure that any lifestyle changes can be maintained in the longer term.

Conclusions

Health trainers may be successful in terms of supporting people from socio-economically disadvantaged communities to make positive lifestyle changes, as well as achieving other health-related outcomes. This is not a ‘one-size-fits-all’ approach; commissioners and providers should select the intervention models that best meet the needs of their local populations. By delivering holistic interventions that address multiple lifestyle risks and incorporate relapse prevention strategies, health trainers could potentially have a significant impact on health inequalities. However, rigorous, formal outcome and economic evaluation of the range of health trainer delivery models is needed.

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. Logistic regressions demonstrated that (1) in general, perceived ineffectiveness was negatively associated with retention; (2) perceived pressure or coercion was negatively associated with retention but only for younger clients; (3) experienced fear and anxiety had no significant association with retention. Implications for theory and counseling practices to reduce motivational barriers and effectively tailor interventions are discussed.

Cost-effectiveness of Methadone Maintenance Treatment in Prevention of HIV Among Drug Users in Shiraz, South of Iran

Background:

The increase in high-risk injections and unsafe sexual behaviors has led to increased HIV infection prevalence among Intravenous Drug Users (IDUs). The high costs of HIV/AIDS care and low financial resources necessitate an economic evaluation to make the best decision for the control of HIV/AIDS.

Objectives:

This study was conducted to determine the cost-effectiveness of Methadone Maintenance Treatment (MMT) centers in HIV infection prevention among drug users.

Materials and Methods:

In this interventional study, we included all the seven MMT centers and the drug users registered there (n = 694). We calculated all the costs imposed on the government, i.e. Provider of case. Mathematical models were used to estimate the number of HIV cases averted from high-risk behaviors. Sensitivity analyses were performed to show the effects of uncertainty in parameters on the number of HIV cases averted and also Incremental Cost-Effectiveness Ratio (ICER).

Results:

Based on the averted models, the selected MMT centers could prevent 128 HIV cases during 1 year. The total cost was $ 547423 and that of HIV/AIDS care in the no intervention scenario was estimated $ 14171816. ICER was $ 106382 per HIV case averted. The results of the sensitivity analysis indicated that MMT intervention was cost-effective even in the worst scenario and ICER varied from $ 39149 to $ 290004 per HIV case averted.

Conclusions:

With regard to the high prevalence of drug injection among drug users and considering the high effectiveness and cost-effectiveness of MMT centers in preventing HIV infection, establishment of MMT centers in regional and national levels seems reasonable.

Listening to Immigrant Latino Men in Rural Oregon

This study explored factors that affect access to and use of sexual and reproductive health services including family planning among immigrant Latino men residing in rural Oregon communities that have experienced a high growth in their Latino population. In-depth interviews were conducted with 49 sexually active men aged 18 to 30 years who recently immigrated to the United States. Findings from content analysis identified multiple overlapping individual-level barriers, including lack of knowledge, perception of personal risk for unintended pregnancy and STIs, and fear of disease. On a service delivery level, structural factors and the importance of confianza when interacting with providers and clinic staff were dominant themes. The majority of these themes were grounded in a cultural context and linked to men’s cultural background, beliefs, and experiences. Examining the needs of immigrant Latino men through this cultural lens may be critically important for improving access and use of sexual and reproductive health services.

HIV prevention interventions to reduce racial disparities in the United States: a systematic review

Racial and ethnic minorities are disproportionately affected by HIV/AIDS in the United States despite advances in prevention methodologies. The goal of this study was to systematically review the past 30 years of HIV prevention interventions addressing racial disparities. We conducted electronic searches of Medline, PsycINFO, CINAHL, and Cochrane Review of Clinical Trials databases, supplemented by manual searches and expert review. Studies published before June 5, 2011 were eligible. Prevention interventions that included over 50% racial/ethnic minority participants or sub-analysis by race/ethnicity, measured condom use only or condom use plus incident sexually transmitted infections or HIV as outcomes, and were affiliated with a health clinic were included in the review. We stratified the included articles by target population and intervention modality. Reviewers independently and systematically extracted all studies using the Downs and Black checklist for quality assessment; authors cross-checked 20% of extractions. Seventy-six studies were included in the final analysis. The mean DB score was 22.44--high compared to previously published means. Most of the studies were randomized controlled trials (87%) and included a majority of African-American participants (83%). No interventions were designed specifically to reduce disparities in HIV acquisition between populations. Additionally, few interventions targeted men who have sex with men or utilized HIV as a primary outcome. Interventions that combined skills training and cultural or interactive engagement of participants were superior to those depending on didactic messaging. The scope of this review was limited by the exclusion of non-clinic based interventions and intermediate risk endpoints. Interactive, skills-based sessions may be effective in preventing HIV acquisition in racial and ethnic minorities, but further research into interventions tailored to specific sub-populations, such as men who have sex with men, is warranted.

Designing an intervention to help people with colorectal adenomas reduce their intake of red and processed meat and increase their levels of physical activity: a qualitative study

Background

Most cases of colorectal cancer (CRC) arise from adenomatous polyps and malignant potential is greatest in high risk adenomas. There is convincing observational evidence that red and processed meat increase the risk of CRC and that higher levels of physical activity reduce the risk. However, no definitive randomised trial has demonstrated the benefit of behaviour change on reducing polyp recurrence and no consistent advice is currently offered to minimise patient risk. This qualitative study aimed to assess patients’ preferences for dietary and physical activity interventions and ensure their appropriate and acceptable delivery to inform a feasibility trial.

Methods

Patients aged 60–74 included in the National Health Service Bowel Cancer Screening Programme (NHSBCSP) were selected from a patient tracking database. After a positive faecal occult blood test (FOBt), all had been diagnosed with an intermediate or high risk adenoma (I/HRA) at colonoscopy between April 2008 and April 2010. Interested patients and their partners were invited to attend a focus group or interview in July 2010. A topic guide, informed by the objectives of the study, was used. A thematic analysis was conducted in which transcripts were examined to ensure that all occurrences of each theme had been accounted for and compared.

Results

Two main themes emerged from the focus groups: a) experiences of having polyps and b) changing behaviour. Participants had not associated polyp removal with colorectal cancer and most did not remember being given any information or advice relating to this at the time. Heterogeneity of existing diet and physical activity levels was noted. There was a lack of readiness to change behaviour in many people in the target population.

Conclusions

This study has confirmed and amplified recently published factors involved in developing interventions to change dietary and physical activity behaviour in this population. The need to tailor the intervention to individuals, the lack of knowledge about the aetiology of colon cancer and the lack of motivation to change behaviour are critical factors.

Optimizing educational video through comparative trials in clinical environments

Although video is increasingly used in public health education, studies generally do not implement randomized trials of multiple video segments in clinical environments. Therefore, the specific configurations of educational videos that will have the greatest impact on outcome measures ranging from increased knowledge of important public health issues, to acceptance of a voluntary HIV test, remain largely unknown. Interventions can be developed to run on affordable handheld computers, including inexpensive tablets or netbooks that each patient can use individually, and to integrate video delivery with automated data collection. These video interventions can then be used not only to educate patients who otherwise might not be reached, but to examine how content can be optimized for greater effectiveness as measured by cognitive and behavioral outcomes. This approach may prove especially valuable in high volume urban facilities, such as hospital emergency departments, that provide points of contact for lower income, lower literacy, and high-risk populations who may not otherwise interact with healthcare providers or researchers. This article describes the development and evaluation of an intervention that educates emergency department patients about HIV prevention and testing while comparatively examining a set of videos, each based upon competing educational theories. The computer-based video intervention and methodology are both highly replicable and can be applied to subject areas and settings far beyond HIV or the emergency department.

Media Literacy Interventions: A Meta-Analytic Review

Although numerous media literacy interventions have been developed and delivered over the past 3 decades, a comprehensive meta-analytic assessment of their effects has not been available. This study investigates the average effect size and moderators of 51 media literacy interventions. Media literacy interventions had positive effects (d=.37) on outcomes including media knowledge, criticism, perceived realism, influence, behavioral beliefs, attitudes, self-efficacy, and behavior. Moderator analyses indicated that interventions with more sessions were more effective, but those with more components were less effective. Intervention effects did not vary by the agent, target age, the setting, audience involvement, the topic, the country, or publication status.

Mano a Mano-Mujer: an effective HIV prevention intervention for Chilean women

The impact of a professionally facilitated peer group intervention for HIV prevention among 400 low-income Chilean women was examined using a quasiexperimental design. At 3 months postintervention, the intervention group had higher HIV-related knowledge, more positive attitudes toward people living with HIV, fewer perceived condom use barriers, greater self- efficacy, higher HIV reduction behavioral intentions, more communication with partners about safer sex, and decreased depression symptoms. They did not, however, have increased condom use or self-esteem. More attention to gender barriers is needed. This intervention offers a model for reducing HIV for women in Chile and other Latin American countries.

Climbing the "ladder of participation": engaging experiential youth in a participatory research project

OBJECTIVES

Street-involved youth are at high risk for acquiring HIV and hepatitis C infection due to potential engagement in high-risk behaviours, including injection drug use. The Youth Injection Prevention (YIP) Project sought to identify factors that prevented street-involved youth from moving into injection drug use in Vancouver, BC. Our project used a participatory research orientation to study these factors. This paper describes the level of participation observed among the street-involved youth taking part in our project.

METHODS

The YIP project employed street-involved youth as co-researchers. To assess the level of participation among the co-researchers, we applied Roger Hart's "Ladder of Youth Participation". Each advancing rung in the ladder represents a higher level of participation. We compared the youth's involvement in the project to the rungs in Roger Hart's tool.

RESULTS

Throughout the duration of the project, the youth's participation increased. Initially the youth had low levels of participation as they were hired based on their life experiences and initially consulted and informed. Over the course of the project, team- and skill-building activities took place. This helped the project environment evolve into a safe space where youth felt comfortable to engage at the highest levels of participation.

CONCLUSION

The YIP Project was successful in being a highly participatory research project. In a safe and open environment, the youth felt comfortable to question and take on initiatives that went beyond the academic researcher's initial expectations. This project highlights the success of engaging street-involved youth in participatory research.

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. An unobtrusive study was conducted to observe enrollment in HIV risk-reduction counseling after measuring partner-violence complaints (e.g., feeling threatened or being hit), emotional complaints (e.g., fatigue or anxiety), and physical complaints (e.g., cardiovascular or digestive symptoms). The sample was a group of 350 participants, 70% clients from a state-health department in North Central Florida and 30% community members. Consistent with predictions, complaints of partner violence had a positive association with enrollment in women but not in men, whereas complaints about physical health had a positive association with enrollment in men, but not in women. Emotional complaints did not predict enrollment in either gender group. This study suggests that broad, gender-specific population needs must be competently addressed within HIV-prevention programs and may be strategically used to increase program enrollment.

Philani Plus (+): a Mentor Mother community health worker home visiting program to improve maternal and infants' outcomes

Pregnant mothers in South African townships face multiple health risks for themselves and their babies. Existing clinic-based services face barriers to access, utilization, and human resource capacities. Home visiting by community health workers (CHW) can mitigate such barriers. The Philani Plus (+) Intervention Program builds upon the original Philani CHW home-visiting intervention program for maternal and child nutrition by integrating content and activities to address HIV, alcohol, and mental health. Pregnant Mothers at Risk (MAR) for HIV, alcohol, and/or nutrition problems in 24 neighborhoods in townships in Cape Town, South Africa (n = 1,239) were randomly assigned by neighborhood to an intervention (Philani Plus (+), N = 12 neighborhoods; n = 645 MAR) or a standard-care control condition of neighborhood clinic-based services (N = 12 neighborhoods; n = 594 MAR). Positive peer deviant "Mentor Mother" CHWs are recruited from the township neighborhoods and trained to deliver four antenatal and four postnatal home visits that address HIV, alcohol, nutrition, depression, health care regimens for the family, caretaking and bonding, and securing government-provided child grants. The MAR and their babies are being monitored during pregnancy, 1 week post-birth, and 6 and 18 months later. Among the 1,239 MAR recruited: 26% were HIV-positive; 27% used alcohol during pregnancy; 17% previously had low-birthweight babies; 23% had at least one chronic condition (10% hypertension, 5% asthma, 2% diabetes); 93% had recent sexual partners with 10% known to be HIV+; and 17% had clinically significant prenatal depression and 42% had borderline depression. This paper presents the intervention protocol and baseline sample characteristics for the "Philani Plus (+)" CHW home-visiting intervention trial.

Race and emotion in computer-based HIV prevention videos for emergency department patients

Computer-based video provides a valuable tool for HIV prevention in hospital emergency departments. However, the type of video content and protocol that will be most effective remain underexplored and the subject of debate. This study employs a new and highly replicable methodology that enables comparisons of multiple video segments, each based on conflicting theories of multimedia learning. Patients in the main treatment areas of a large urban hospital's emergency department used handheld computers running custom-designed software to view video segments and respond to pre-intervention and postintervention data collection items. The videos examine whether participants learn more depending on the race of the person who appears onscreen and whether positive or negative emotional content better facilitates learning. The results indicate important differences by participant race. African American participants responded better to video segments depicting White people. White participants responded better to positive emotional content.
