Black social media influencers engage higher percentages of Black gay and bisexual men in online outreach for HIV prevention research relative to paid ads.

Background: Influencer-based social media marketing campaigns are a popular strategy to engage customers in many non-research industries (e.g., retail), but have been increasingly used in public health campaigns to reach and engage specific populations. However, few studies have directly compared the performance of influencer-based marketing with other ad strategies (e.g., paid ads) in achieving these goals. Methods: From March to September 2023, we conducted an influencer-focused marketing campaign in which we identified and partnered with predominantly Black LGBTQ + influencers in the United States South to promote engagement in our ongoing research. We then used web analytics and interest form data to compare performance of influencer posts versus paid ads over the same time period. Results: We contacted a total of 358 influencers, 20 of whom ultimately agreed to post (85% Black/African American) and made a total of 28 posts on our behalf. A significantly higher percentage of users who clicked through influencer posts were Black (40% vs. 15%), were not currently using pre-exposure prophylaxis (PrEP) (67% vs. 62%), had no history of PrEP use (78% vs. 72%), and reported higher medical mistrust (12% vs. 8%) compared to those who clicked through paid ads. The percentage of Black men who have sex with men who were at high HIV risk, who were not taking PrEP, had no history of PrEP, or were high in mistrust, were all 2-3 times higher among those who clicked through influencer posts relative to paid ads. Conclusions: Influencer-focused marketing may be a powerful tool to efficiently reach and engage high-priority and hard to reach populations.

Challenges in implementing cultural adaptations of digital health interventions.

Differences in the access and use of digital health interventions are driven by culture, in addition to economic and physical factors. To avoid the systematic exclusion of traditionally underserved cultural groups, creating inclusive digital health interventions is essential. One way to achieve this is through cultural adaptations, defined as the systematic modification of an existing intervention that aligns with a target audience's cultural norms, beliefs, and values. In theory, cultural adaptations can potentially increase the reach and engagement of digital health interventions. However, the evidence of whether and how that is achieved is limited. Justifying, planning, and implementing an adaptation comes with various challenges and takes time and money. This perspective provides a critical overview of the field's current state and emphasizes the need for technology-specific frameworks that address when and how to culturally adapt digital health interventions.

Pilot Randomized Controlled Trial of Game Plan for PrEP: A Brief, Web and Text Message Intervention to Help Sexual Minority Men Adhere to PrEP and Reduce Their Alcohol Use.

Suboptimal adherence to oral PrEP medications, particularly among younger sexual minority men (SMM), continues to be a key barrier to achieving more substantial declines in new HIV infections. Although variety of interventions, including web and text-message-based applications, have successfully addressed PrEP adherence, very few have addressed the potential influence of alcohol. This pilot study explored whether the Game Plan for PrEP, a brief, web-based and text messaging intervention, helped promote PrEP persistence and adherence and reduced condomless sex and alcohol use. Seventy-three heavy-drinking SMM on PrEP were recruited online from states with Ending the HIV Epidemic jurisdictions and randomly assigned 1:1 to receive either the Game Plan for PrEP intervention or an attention-matched control. We collected online surveys assessing primary outcomes at one, three, and six months post-enrollment. As secondary outcomes, we also collected dried blood spot samples at baseline, three, and six months to analyze for biomarkers of PrEP and alcohol use. Our results showed that the odds of stopping PrEP or experiencing a clinically meaningful lapse in PrEP adherence (≥ 4 consecutive missed doses) were not different across the two conditions. We also did not find evidence of any differences in condomless sex or drinking outcomes across conditions, although participants in both conditions reported drinking less often over time. These findings were consistent across both self-reported outcomes and biomarkers. Overall, we did not find evidence that our brief, web and text messaging intervention encouraged more optimal PrEP coverage or moderate their alcohol use.

Using web analytics data to identify platforms and content that best engage high-priority HIV populations in online and social media marketing advertisements.

Background: Online advertisements on social media platforms are an important tool for engaging relevant populations in public health research. However, little is known about what platforms and ad characteristics are most effective in engaging high-priority HIV populations, including racial/ethnic and sexual minority individuals. Methods: Data from this study were drawn from advertising campaigns conducted on popular websites and social media platforms that recruited for several nationwide randomized controlled trials of various HIV prevention and testing strategies among sexual minority men (SMM) from December 2019 until March 2022. Descriptive statistics and LASSO regression models were used to determine which platforms and ad characteristics were associated with significantly higher odds of engagement. Results: Ads on Google search, Facebook, and Instagram yielded the most cost-effective engagement, while gay-oriented dating platforms and TrafficJunky yielded the highest percentage of users who appeared to meet basic eligibility criteria. The highest percentages of Black users were screened through ads on Jack'd, TrafficJunky, and Google search; for Hispanic/Latino users, Google search, Grindr, Facebook, and Instagram. Analyzing ad characteristics, we found ads that used suggestive content, animation, and included study or institution logos were associated with greater engagement. Ads that emphasized convenience of the research (e.g. mentioned participating "from home") and that depicted people of similar races/ethnicities were also associated with greater engagement among Black and Hispanic/Latino sexual minority men. Conclusions: We found that advertisements on mainstream social media sites are most cost effective. Although gay-oriented dating platforms were much more effective at reaching the target population, they were considerably more expensive. We also identified ad characteristics that were particularly effective in engaging users. These results could inform the design of online public health outreach campaigns for similar populations to improve their engagement and reach. Findings also demonstrated the value of conducting focused research on the effectiveness of various online marketing strategies.

Patient Perceptions of In Vivo Versus Virtual Reality Exposures for the Treatment of Anxiety Disorders: Cross-Sectional Survey Study.

BACKGROUND: Psychotherapy, and particularly exposure therapy, has been proven to be an effective treatment for many anxiety disorders, including social and specific phobias, as well as posttraumatic stress disorders. Currently, exposures are underused and mostly delivered in vivo. Virtual reality exposure therapy (VRET) offers a more flexible delivery mechanism that has the potential to address some of the implementation barriers of in vivo exposures while retaining effectiveness. Yet, there is little evidence on how patients perceive different exposure therapy methods. OBJECTIVE: This study aims to explore the perceptions of individuals with anxiety disorders toward in vivo and VRET. Our findings can inform therapists about the degree of patient interest in both methods while exploring the demand for VRET as an alternative and novel treatment approach. METHODS: Web-based survey assessing the (1) interest in, (2) willingness to use, (3) comfort with, (4) enthusiasm toward, and (5) perceived effectiveness of exposure therapy when delivered in vivo and through VR. Participants included individuals with specific phobia, social phobia, posttraumatic stress disorder, or acute stress disorder or reaction. Participants were presented with educational videos about in vivo and VRET and asked to provide their perceptions quantitatively and qualitatively through a rated scale and free-text responses. RESULTS: In total, 184 surveys were completed and analyzed, in which 82% (n=151) of participants reported being willing to receive in vivo exposures and 90.2% (n=166) reported willingness to receive VRET. Participants reported higher interest in, comfort with, enthusiasm toward, and perceived effectiveness of VRET compared to in vivo. Most reported in vivo concerns were linked to (1) increased anxiety, (2) feelings of embarrassment or shame, and (3) exacerbation of current condition. Most reported VRET concerns were linked to (1) risk of side effects including increased anxiety, (2) efficacy uncertainty, and (3) health insurance coverage. The most frequently mentioned VRET benefits include (1) privacy, (2) safety, (3) the ability to control exposures, (4) comfort, (5) the absence of real-life consequences, (6) effectiveness, and (7) customizability to a wider variety of exposures. CONCLUSIONS: On average, our participants expressed positive perceptions toward exposure therapy, with slightly more positive perceptions of VRET over in vivo exposures. Despite valid personal concerns and some misconceptions, our findings emphasize that VRET provides an opportunity to get much-needed therapy to patients in ways that are more acceptable and less concerning.

Virtual reality (VR) treatments for anxiety disorders are unambiguously successful, so why are so few therapists using it? Barriers to adoption and potential solutions.

Anxiety disorders are a significant cause of disability globally, yet only one in ten sufferers receives adequate quality treatment. Exposure-based therapies are effective in reducing symptoms associated with a number of anxiety disorders. However, few therapists use exposure techniques to treat these conditions, even when they are adequately trained in them, often because of concerns about provoking distress, drop out, logistical barriers, and other concerns. Virtual reality exposure therapy (VRET) can address many of these concerns, and a large body of research decisively shows that VRET is as efficacious for treating these conditions as in vivo exposures. Yet, use of VRET remains low. In this article, we discuss several factors we believe are contributing to low VRET adoption among therapists and raise potential solutions to address them. We consider steps that VR experience developers and researchers might take, such as leading studies of VRET's real-world effectiveness and treatment optimization trials and continuing to improve the fit of platforms with clinicians' workflows. We also discuss steps to address therapist reservations using aligned implementation strategies, as well as barriers for clinics, and the roles that professional organizations and payers could have in improving care by encouraging adoption of VRET.

Adolescents' perceptions of alcohol portrayals in the media and their impact on cognitions and behaviors.

OBJECTIVE: Exposure to alcohol in the media is pervasive and may influence adolescents' perceptions and use of alcohol. The purpose of this study was to better understand how adolescents perceive alcohol-related content in both entertainment and social media, with a focus on the valence of portrayals (i.e., positive, negative) and impacts on cognitions and behaviors. METHOD: Participants were 40 high school students (60% female). Nine focus groups were conducted via videoconferencing, stratified by grade (9th/10th, 11th/12th) and gender. Transcripts were analyzed via template-style thematic analyses to identify themes. RESULTS: Six themes were developed, including (a) some portrayals of alcohol may increase likelihood of using alcohol, (b) some portrayals of alcohol in the media can discourage drinking, (c) sometimes truly negative consequences of alcohol are portrayed positively or downplayed, (d) media portrayals of alcohol are perceived to be based in reality but are at times exaggerated, (e) adolescent and adult alcohol use is portrayed differently in entertainment media, and (f) the extent to which adolescents are influenced by the media may depend on their preexisting attitudes, beliefs, and education. CONCLUSIONS: Adolescents have awareness of media portrayals of alcohol, both positive and negative, and their associated impacts. Findings highlight the need for much more work to understand the conditions under which, and for whom, exposure to different types of positive portrayals of alcohol in the media translate into positive expectancies about alcohol or drinking motives. Such work may ultimately inform intervention targets to reduce early initiation and/or risky drinking among adolescents. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Emotional Reactions to High-Risk Sex among Sexual Minority Men: Exploring Potential Opportunities for Just-In-Time Intervention.

Rates of HIV and other sexually transmitted infections (STIs) are high among sexual minority men (SMM). A large body of research has explored determinants of HIV/STI risk behavior, but few studies have explored emotional consequences of these events. Understanding the valence, timing, and strength of emotional reactions to sexual risk could inform use of specific behavior change techniques in interventions (such as anticipated regret) and identify new opportunities for intervention, including just-in-time interventions. We analyzed data from an ecological momentary assessment (EMA) study of 100 HIV-negative/unknown-status SMM to understand patterns of positive affect, negative affect, shame, and stress in the 24 hours after sex. Mixed-effects models showed that the probability of negative affect was higher in the hours following condomless anal sex (CAS) with high-risk partners during which SMM reported being under the influence of alcohol or drugs (A/D involved CAS), versus all other types of sex events (OR = 0.92, SE = 0.03, p = .017). The probability of shame was also higher after A/D-involved CAS, versus other sex events (OR = 1.14, SE = 0.07, p = .035). Findings suggest that the hours following A/D-involved CAS events may be an opportune time to intervene to help SMM avoid similarly aversive experiences in the future.

Feasibility, Appropriateness, and Willingness to Use Virtual Reality as an Adjunct to Counseling among Addictions Counselors.

INTRODUCTION: Research suggests that virtual reality (VR) experiences can be helpful as adjunctive tools in psychotherapy for some mental health conditions. VR is a computer-generated experience that produces a feeling of being immersed in a different environment. VR experiences could be useful in the treatment of substance use disorders, and several are currently being tested. However, few psychotherapists report using VR experiences in their practices, even when doing so is well-supported. Understanding key barriers and concerns about using VR among drug/alcohol counselors is important to ultimately encouraging adoption. METHODS: Licensed counselors (N = 101) who provide treatment to clients with substance use disorders were recruited via email Listservs, professional organizations, and social media. Participants viewed a 15-minute educational video about VR and then completed a survey of their views about using it with their clients. RESULTS: Most clinicians (82%) believed they would be likely to use a VR experience in drug/alcohol counseling, and 81% believed it would be appropriate for most of their clients. A minority (19%) noted important concerns, including that their clients may be skeptical of it (15%), cost (14%), and space (10%). Those who had cost and space concerns were less likely to report high use intentions (OR = 0.29 and OR = 031, both p < .05, respectively). CONCLUSIONS: Findings suggest that addictions counselors are eager to use VR, but key barriers should be addressed. VR developers should incorporate features to encourage trust among users, design experiences for small spaces, and explore ways of supporting the purchase of VR systems for counselors.

Using Social Media for Clinical Research: Recommendations and Examples From the Brown-Lifespan Center for Digital Health.

Social media integration into research has increased, and 92% of American social media participants state they would share their data with researchers. Yet, the potential of these data to transform health outcomes has not been fully realized, and the way clinical research is performed has been held back. The use of these technologies in research is dependent on the investigators' awareness of their potential and their ability to innovate within regulatory and institutional guidelines. The Brown-Lifespan Center for Digital Health has launched an initiative to address these challenges and provide a helpful framework to expand social media use in clinical research.

Exploring Whether Addictions Counselors Recommend That Their Patients Use Websites, Smartphone Apps, or Other Digital Health Tools to Help Them in Their Recovery: Web-Based Survey.

BACKGROUND: Hundreds of smartphone apps or websites claiming to help those with addictions are available, but few have been tested for efficacy in changing clinically relevant addictions outcomes. Although most of these products are designed for self-facilitation by users struggling with addictions, counselors and other addictions treatment providers will likely play a critical role in facilitating adoption by integrating their use into counseling or recommending them to their patients. Yet, few studies have explored the practices of addictions counselors in using or recommending addictions-focused digital health tools in their work. OBJECTIVE: The aim of this study was to understand whether addiction counselors are recommending that their patients use addictions-focused apps to help them in their recovery, and the factors that affect their desire to do so. METHODS: Licensed addiction counselors practicing in the United States (N=112) were recruited from professional and scientific organizations of alcohol or drug counselors to complete a web-based survey. RESULTS: In total, 74% (83/112) of counselors had recommended that their patients use a website or smartphone app to assist them in recovery, and those that had done so reported recommending an app with an average of 54% of their patients. The most commonly recommended app or website was SMARTRecovery.org (9%), I am Sober (8%), In the Rooms (7%), Insight Timer (4%), Calm (4%), Sober Tool (4%), Recovery Box (3%), and Sober Grid (3%). The most important reason that counselors recommended the websites or apps was that colleagues or patients told them they found it helpful (55%), followed by their workplaces recommending it (20%) and professional organizations recommending it (10%). Counselors' intentions to recommend a hypothetical app were strongest for apps that had been tested in rigorous, scientific studies that showed they helped users stay sober or reduce their substance use; 94% (105/112) reported that they would "definitely" or "probably" use such an app. CONCLUSIONS: Most addictions counselors surveyed are already recommending that their patients use apps or websites to help them in their recovery, despite the paucity of available products that have evidence supporting their efficacy for addictions outcomes. One way that product developers could increase adoption among addictions treatment providers is to make efficacy testing a priority and to disseminate results through professional organizations and clinics.

Gay, Bisexual, and Other Men Who Have Sex With Men Who Are Not on Oral PrEP may be Less Interested in Available Injectable Products than in Oral PrEP: Examining Individual-Level Determinants of Interest and Barriers Across Products.

Approval of the first injectable PrEP product (cabotegravir) provides an exciting addition to oral PrEP that could encourage those not currently on PrEP to use it. However, few studies have explored interest in injectable cabotegravir among those at increased risk who are not currently on PrEP. We conducted an online survey with 327 gay, bisexual, and other men who have sex with men (GBM) with limited PrEP history to explore their interest and intentions to use oral and injectable PrEP (cabotegravir), and examine barriers and individual-level predictors of both product types. Results showed that 17% of participants who reported being uninterested/neutral about oral PrEP expressed interest in injectable PrEP. Slightly more racial/ethnic minority GBM who were uninterested/neutral for oral PrEP expressed interest in injectable PrEP than White GBM (23% vs. 14%). Determinants were similar across PrEP types. Findings can directly inform interventions encouraging use of both PrEP products.

Game Plan-a Brief Web-Based Intervention to Improve Uptake and Use of HIV Pre-exposure Prophylaxis (PrEP) and Reduce Alcohol Use Among Gay and Bisexual Men: Content Analysis.

BACKGROUND: HIV pre-exposure prophylaxis (PrEP) has considerable potential for reducing incidence among high-risk groups, such as gay, bisexual, and other men who have sex with men (GBM). However, PrEP's effectiveness is closely linked with consistent use, and a variety of individual-level barriers, including alcohol use, could impede optimal uptake and use. Web-based interventions can encourage medication adherence, HIV prevention behaviors, and responsible drinking and may help support PrEP care, particularly in resource-limited settings. OBJECTIVE: We previously developed a web application called Game Plan that was designed to encourage heavy drinking GBM to use HIV prevention methods and reduce their alcohol use and was inspired by brief motivational interventions. This paper aims to describe the web-based content we designed for integration into Game Plan to help encourage PrEP uptake and consistent use among GBM. In this paper, we also aim to describe this content and its rationale. METHODS: Similar to the original site, these components were developed iteratively, guided by a thorough user-centered design process involving consultation with subject-matter experts, usability interviews and surveys, and user experience surveys. RESULTS: In addition to Game Plan's pre-existing content, the additional PrEP components provide specific, personal, and digestible feedback to users about their level of risk for HIV without PrEP and illustrate how much consistent PrEP use could reduce it; personal feedback about their risk for common sexually transmitted infections to address low-risk perceptions; content challenging common beliefs and misconceptions about PrEP to reduce stigma; content confronting familiar PrEP and alcohol beliefs; and a change planning module that allows users to select specific goals for starting and strategies for consistent PrEP use. Users can opt into a weekly 2-way SMS text messaging program that provides similar feedback over a 12-week period after using Game Plan and follows up on the goals they set. CONCLUSIONS: Research preliminarily testing the efficacy of these components in improving PrEP outcomes, including uptake, adherence, sexually transmitted infection rates, and alcohol use, is currently ongoing. If supported, these components could provide a scalable tool that can be used in resource-limited settings in which face-to-face intervention is difficult.

Game Plan, a Web-Based Intervention to Improve Adherence and Persistence to HIV Pre-exposure Prophylaxis and Reduce Heavy Drinking in Gay, Bisexual, and Other Men Who Have Sex With Men: Usability and User Experience Testing.

BACKGROUND: Encouraging consistent use of pre-exposure prophylaxis (PrEP) is essential for reducing HIV incidence, particularly among gay, bisexual, and other men who have sex with men (GBM), and especially those who engage in heavy drinking. Although practice guidelines recommend providing adherence counseling to PrEP patients, clinics and providers may not have the resources or expertise to provide it. Internet-facilitated interventions have been shown to improve HIV prevention outcomes, including medication and care adherence. Game Plan is a website we created to help users make a tangible plan for reducing their HIV risk. We designed additional components of Game Plan to address key individual level barriers to PrEP use. OBJECTIVE: The aim of this mixed methods research is to test the usability and user experience of these components with intended users: GBM who drink heavily and are on PrEP. METHODS: In study 1 (usability), we completed a detailed individual interview in which participants (n=10) walked through a prototype of the website, thinking aloud as they did, and completed a follow-up interview and web-based survey afterward. Study 2 (user experience) involved providing participants (n=40) with a link to the prototype website to explore on their own and asking them to complete the same follow-up survey afterward. Qualitative data were analyzed using thematic analysis, and descriptive statistics were used to analyze quantitative data. RESULTS: Users in both studies gave the website excellent ratings for usability, overall satisfaction, and quality, and most often described the site as informative, helpful, and supportive. Users also rated the site's content and feel as respectful of them and their autonomy, empathetic, and they stated that it conveyed confidence in their ability to change. The study 1 interviews highlighted the importance of the website's esthetics to the participants' engagement with it and its credibility in prompting genuine reflection. CONCLUSIONS: GBM who reported heavy drinking and used PrEP generally found a website focused on helping them to create a plan to use PrEP consistently to be helpful. Adopting user-centered design methods and attending to the esthetics of mobile health interventions are important steps toward encouraging engagement and reducing at-risk behaviors.

Cognitive-emotional mechanisms of alcohol intoxication-involved HIV-risk behavior among men who have sex with men (MSM).

Alcohol use is a key risk factor for HIV infection among men who have sex with men (MSM), primarily because it interferes with condom use. However, little is known about the cognitive-emotional mechanisms through which alcohol influences decisions to use condoms with high-risk partners among MSM. In this study, we tested whether alcohol-related deficits in inhibitory control and attention bias toward sexual cues (vs. condoms and neutral cues) accounted for increases in condomless anal sex (CAS) intentions after drinking among MSM. Heavy-drinking, high-risk MSM (N = 83) were randomly assigned to receive (a) alcohol, (b) placebo, or (c) control beverages before behavioral tasks assessing inhibitory control and attention bias, and a video-based sexual risk scenario that assessed several aspects of sexual decision making. Results showed that inhibitory control and attention bias to sexual cues did not mediate associations between intoxication and CAS intentions. Inhibitory control deficits also did not moderate the indirect effects of intoxication on CAS intentions through attention bias. Three-way interactions between alcohol/placebo condition, inhibitory control, and attention bias were also not significant. Together, these findings provide little evidence that these two processes play a significant role in alcohol-involved HIV risk, at least as assessed by the specific tasks used in this study.

eTest: a limited-interaction, longitudinal randomized controlled trial of a mobile health platform that enables real-time phone counseling after HIV self-testing among high-risk men who have sex with men.

BACKGROUND: HIV disproportionately affects men who have sex with men (MSM) in the USA, and new infections continue to increase, particularly among African American (AA) and Hispanic/Latino (H/L) MSM. Rates of HIV testing are particularly low among AA and H/L MSM, and innovative approaches to encourage testing may help address high incidence in these men. HIV self-testing (HST) may be an important tool for increasing rates and frequency of testing. HST may be particularly well-suited for AA and H/L MSM, given that stigma and mistrust of medical care contribute to low testing rates. Despite its promise, however, many are concerned that HST does not sufficiently connect users with critical post-testing resources, such as confirmatory testing and care among those who test positive, and that these limitations may result in delayed linkage to care. METHODS: We developed a mobile health platform (eTest) that monitors when HST users open their tests in real time, allowing us to provide timely, "active" follow-up counseling and referral over the phone. In this study, 900 high-risk MSM (with targets of 40% AA, 35% H/L) who have not tested in the last year will be recruited from social media and other gay-oriented websites in several major cities. Over 12 months, participants will be randomly assigned to receive (1) HST with post-test phone counseling and referral (eTest condition), (2) HST without active follow-up (standard condition), or (3) reminders to get tested for HIV at a local clinic (control) every 3 months. Primary outcomes include rates of HIV testing, receipt of additional HIV prevention services, and PrEP initiation verified by clinical medical records. DISCUSSION: This study tests whether providing more active counseling and referral after HST encourages more regular HIV testing and engagement with other prevention services among MSM, compared to more passive approaches or clinic-based testing alone. It will also explore the cost-effectiveness and emotional/behavioral effects of these two strategies. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT03654690 . Registered on 31 August 2018.

Assessment of Alcohol Use and Consequences: Comparison of Data Collected Via Timeline Followback Interview and Daily Reports.

OBJECTIVE: The aim of this study was to compare data on both alcohol use and alcohol-related consequences between intensive longitudinal data collection and the retrospective Timeline Followback (TLFB) interview. METHOD: Heavy drinking college students (n = 96; 52% women) completed daily reports across a 28-day period to assess alcohol use and positive and negative consequences of drinking. They returned to the lab at the end of this period to complete a TLFB assessing behavior over those same 28 days. First, t tests were used to compare variables aggregated across the full 28 days at the between-person level. Next, hierarchical linear modeling was used to examine within-person differences between methods for each variable in weekly and daily increments. RESULTS: Many alcohol use and consequence variables were significantly different when derived from self-reports during TLFB versus daily reports. In contrast to prior work, we found that higher estimates of drinking were reported retrospectively on the TLFB than on the daily reports. In addition, discrepancies were greater on some variables for heavier drinkers and when more time had elapsed between the end of the daily reporting period and TLFB collection. CONCLUSIONS: Recall of drinking behavior during TLFB and daily reports may differ in systematic ways, with discrepancies varying based on participant and methodological characteristics.

Using the Internet to access key populations in ecological momentary assessment research: Comparing adherence, reactivity, and erratic responding across those enrolled remotely versus in-person.

Ecological momentary assessment (EMA) is a set of longitudinal methods that researchers can use to understand complex processes (e.g., health, behavior, emotion) in "high resolution." Although technology has made EMA data collection easier, concerns remain about the consistency and quality of data collected from participants who are enrolled and followed online. In this study, we used EMA data from a larger study on HIV-risk behavior among men who have sex with men (MSM) to explore whether several indicators of data consistency/quality differed across those who elected to enroll in-person and those enrolled online. One hundred MSM (age 18-54) completed a 30-day EMA study. Forty-five of these participants chose to enroll online. There were no statistically significant differences in response rates for any survey type (e.g., daily diary [DD], experience sampling [ES], event-contingent [EC]) across participants who enrolled in-person versus online. DD and ES survey response rates were consistent across the study and did not differ between groups. EC response rates fell sharply across the study, but this pattern was also consistent across groups. Participants' responses on the DD were generally consistent with a poststudy follow-up Timeline Followback (TLFB) with some underreporting on the TLFB, but this pattern was consistent across both groups. In this sample of well-educated, mostly White MSM recruited from urban areas, EMA data collected from participants followed online was as consistent, reliable, and valid as data collected from participants followed in-person. These findings yield important insights about best practices for EMA studies with cautions regarding generalizability. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Using ecological momentary assessment (EMA) to explore mechanisms of alcohol-involved HIV risk behavior among men who have sex with men (MSM).

BACKGROUND AND AIMS: Heavy drinking is associated with increased risk of incident HIV infection among men who have sex with men (MSM). Past studies suggest that this association may be due to the tendency for intoxication to interfere with condom use. However, research on potential causal mechanisms explaining this relationship has been limited primarily to laboratory studies. In this study, we tested several potential mediators of the relationship between alcohol use level and HIV risk behavior. DESIGN: Ecological momentary assessment (EMA) methods conducted over a 30-day period. SETTING AND PARTICIPANTS/CASES: MSM (n = 100) in the northeastern United States. MEASUREMENTS: Participants completed daily diary surveys and up to six experience sampling surveys randomly prompted throughout the day. FINDINGS: Very heavy levels of drinking (12+ drinks) increased the odds of engaging in any sex [odds ratio (OR) = 1.87, P < 0.001]. Coefficient products and 95% confidence intervals indicated that both subjective sexual arousal (OR = 1.52, P < 0.001) and sex intentions (OR = 1.74, P < 0.001) significantly mediated the association between very heavy drinking and the odds of sex. When participants reported sex, the odds of engaging in high-risk condomless anal sex (CAS) increased incrementally after drinking heavily (five to 11 drinks; OR = 3.27, P = 0.006) and very heavily (12+ drinks; OR = 4.42, P < 0.001). Only subjective sexual arousal significantly mediated the association between alcohol use level and high-risk CAS (OR = 1.16, P = 0.040). CONCLUSIONS: Increases in subjective sexual arousal after drinking heavily appear to partly account for alcohol-related HIV risk behaviors in the daily lives of men who have sex with men. Alcohol's role in strengthening motivationally consistent emotional states may therefore play a more important role in facilitating alcohol-involved HIV risk than explicit sexual motivation.
