Abstract
Interventions addressing the sexual health need of HIV-positive men who have sex with men (MSM) in Latin America are scarce. We adapted and evaluated GPS, a group-based intervention led by peers, developed using the Information-Motivation-Behavioral (IMB) model and motivational interviewing (MI). We used McKleroy et al framework to culturally adapt GPS to MSM living with HIV infection in Colombia. Then, a one-armed pilot trial examined changes in depressive symptoms, loneliness, self-efficacy for engaging in sexual risk reduction behaviors, sexual sensation seeking and sexual compulsivity at pre-intervention, post-intervention, and 3-month follow-up. These results were complemented with semistructured interviews with participants 3 months after the intervention. GPS was identified to be culturally acceptable with few changes in materials and exercises. Facilitators showed high levels of adherence and fidelity to MI principles. Seven of 11 eligible participants finished the intervention; GPS positively influenced self-efficacy for condom negotiation, depressive symptoms, and condomless anal sex with partners of unknown HIV status. Exit interviews revealed that GPS was well-designed, relevant, facilitated discussion of sex in a nonjudgmental manner, and helped make positive changes in participants’ sexual lives. These results provided preliminary evidence of an intervention to address sexual and mental health of MSM living with HIV in Latin America.
Keywords
With people living with HIV infection (PLWH) having longer and more sexually active lives, it is of the utmost importance to have interventions available to address the psychosocial, physical, mental, and sexual needs of PLWH. Interventions to address these needs or Prevention with Positives demonstrate that providing education as well as comprehensive counseling strategies can reduce risky behaviors in men who have sex with men (MSM) living with HIV infection (Crepaz et al., 2006), and increase adherence to medications and retention to care (Crepaz et al., 2015). Positive prevention interventions have been effective in reduction of depression, isolation, stigma, and discrimination (Van Der Heijden et al., 2017). These interventions acquire greater relevance in contexts where structural barriers exist and where adherence to ART and retention to care are still below recommended goals, such as in the case of Colombia.
It is estimated that 120,000 individuals, most of whom are MSM, are living with HIV infection in Colombia. Only 54% of people with HIV are currently receiving antiretroviral therapy and nearly 39% of them have detectable viral loads (Unaids, 2017). Structural and individual factors affect access and adherence to antiretroviral therapy in Colombia, with a lack of health insurance being among the greatest barriers. Few studies in Colombia have explored the psychosocial and sexual needs of people living with HIV, and these have reported high levels of stigma and depression (Mueses-Marin et al., 2019) and frequent inconsistent condom use (Zea et al., 2015). There is no established program in Colombia to promote HIV risk reduction in any population group (Mora-Rojas et al., 2017); antiretroviral used for Pre-exposure Prophylaxis was approved in Colombia in 2019.
The main purpose was to adapt and pilot the acceptability, appropriateness, and effectiveness of Gay Poz Sex: Finding your own way in Latino MSM. The study was conducted in an HIV clinic in Colombia and involved the collaboration of Canadian and Colombian HIV researchers, and experienced MSM living with HIV infection who had previously delivered the intervention in English.
Methods
GPS: Finding Your Own Way
GPS was developed to fill an important gap of Prevention with Positives in North America. GPS is as a confidential, group-based, peer-led program that supports PLWH in making choices related to their sexual, mental, and physical health (Hart, Stratton et al., 2016). GPS is based on the IMB skills theoretical model (Fisher & Fisher, 1992) and uses Motivational Interviewing-based (MI) counseling (Miller & Rollnick, 2009). The IMB approach to change in health behavior asserts that information, motivation, and behavioral skills are fundamental determinants of a wide range of health-related behaviors. The MI component of GPS encourages participants to identify their own goals and make healthy decisions based on their own values, concerns, or beliefs (Hart, Willis et al., 2016). MI has been identified to be effective in other interventions to address the needs of PLWH (Adamian et al., 2004; Diiorio et al., 2008). GPS was demonstrated to be efficacious in a Canadian randomized controlled trial with 183 MSM living with HIV, showing significant reductions in sexual compulsivity and a 43% relative reductions in Condomless Anal sex (CAS) with HIV-negative partners compared to treatment-as-usual (Hart et al., In Press).
Adaptation and Evaluation
This study was carried out in three phases: First, we adapted GPS for Latino MSM in both Canada and Colombia. Second, we trained individuals to become GPS facilitators and third, we piloted the adapted GPS version. We used a mixed-methods approach with convergent design that included an adaptation design with predominantly qualitative methods, a single-arm trial design with quantitative assessments of intervention outcomes, and semistructured interviews done 3 months after intervention to assess participants’ perceptions of GPS. The study protocol was approved by the (Blinded for Review). There were no protocol deviations or adverse events.
Phase 1: Adaptation Process
The adaptation process was based on the method described by McKleroy et al. (2006), which consists of five different steps: assess, select, prepare, pilot, and implement. The first step was to identify the priority populations, the intervention possibilities, the capacity of the organization(s), and the interest of the communities. This work was done in Canada in 2013 and in Colombia in 2014, where input from community leaders and researchers working on HIV related interventions were obtained about potential interventions. GPS was, then, selected (second step) for several reasons: first, peers delivered the intervention; second, it uses a broad concept of sexual health; and third, GPS had demonstrated efficacy The third step of the adaptation was the preparation of the intervention. In this case, two Latino peer facilitators residing in Canada were selected to learn to become GPS facilitators. Both received a total of 48 hr of training that included experiencing GPS as participants, training in MI, and delivery of GPS back to their trainers. Two Canadian GPS facilitators, one of whom is a member of the MI Network of Trainers (MINT) (Wingood & Diclemente, 2008), delivered the training in GPS. During this training, both Latino facilitator trainees translated all GPS materials from English into Spanish and completed a preliminary adaptation of GPS. GPS was then refined and pretested in Canada with five Latino MSM living with HIV infection using a methodology called “theater testing,” where the facilitators delivered GPS to the five “mock participants” (Wingood & Diclemente, 2008). Qualitative and quantitative data were obtained from the five “mock participants” at the end of each of the eight GPS sessions. Then, the intervention was further refined in Colombia. One of the Latino GPS facilitators residing in Canada traveled to Cali and delivered the GPS intervention using the “theater testing” process again with five participants living with HIV infection residing in Cali. During this process, the questionnaires and the implementation plan were adjusted. Comments from the participants were used to assess the initial appropriateness of the program and to make final adjustments to the adapted GPS version to be piloted (step four of the McKleroy process).
Phase 2: Training of Colombian Facilitators
To be eligible to participate as a GPS facilitator in Cali, a participant had to identify as MSM and be living with HIV infection, be over 18 years of age, and have Spanish-language fluency. Two facilitators were chosen among ten candidates that applied. They received 15 hr of training in MI (over 2 days), which was delivered by a professional psychologist with experience in working with PLWH (DC), and experienced GPS as participants. Finally, they received three additional days of training where they delivered GPS to each other and practised basic techniques of MI. To maintain the fidelity of the MI and the GPS intervention, the psychologist who delivered the MI training rated each facilitator’s adherence to motivational interviewing (Moyers et al., 2010). Fidelity scores were 25/25 for one facilitator and 23/25 for the other facilitator,
Phase 3: Piloting the Adapted Version of GPS
Quantitative Data Collection
Individuals who were eligible to participate were invited through local advertisements displayed at the CLS clinic and advertisements in MSM organizations. To be eligible, participants needed to identify as MSM, report engaging in CAS with another male during the past 3 months, self-report as living with HIV infection, and be at least 18 years old. All participants provided written informed consent at the beginning of the study. Participants attended eight weekly 2-hr group sessions led by the two Colombian facilitators. Individuals who consented to participate in the pilot phase were assessed at baseline, at the end of GPS sessions, and 3 months later using the same questionnaire.
The questionnaire included the sociodemographic characteristics of participants, including employment status, education level, annual income, and years since HIV diagnosis. If the participant was on ART, he was asked about his viral load (i.e., detectable, undetectable, or unknown). Similar to previous research on GPS, we assessed six psychosocial constructs at each timepoint (details are provided in Table 1): depression, fear of being sexually rejected, self-efficacy, Sexual Sensation Seeking, loneliness, and sexual compulsivity. The final scales translated in Spanish and used in the study are available upon request. The final set of questions related to sexual behavior. As per the original GPS program in English, a primary outcome of GPS is reducing the point-prevalence of CAS with partners of HIV-negative or unknown status. CAS in the last 3 months was defined as having at least one insertive or receptive anal sex encounter without a condom. Based on this definition the following outcomes were defined, CAS with: (a) regular partner, (b) casual partner living with HIV infection, (c) casual partner not living with HIV infection, and (d) casual partners of unknown HIV status.

Quantitative data analyses were conducted using STATA (Stata, 2013). Frequencies and univariate analyses were calculated for sociodemographic variables, sexual behaviors, and for each psychosocial measure used in these analyses. The data are reported for each time period: baseline, post-intervention, and 3-month follow-up. Given the lack of power to conduct t-paired or mixed models, only descriptive analysis over time is presented.
Qualitative Data Collection
Semi-structured one-to-one interviews were conducted 3 months after the intervention to collect detailed information about the participants’ perceptions of GPS. Only those who completed the intervention were invited, with six of them providing information. Participants were approached by phone by the research team and invited to a face-to-face or phone interview. Face to face interviews were done in private in CLS. The interview was guided by the following questions: What aspects of GPS did or did not work for you? What was your goal for change in GPS? How did GPS help you to achieve that goal? Would you recommend GPS to friends? Which aspects of GPS would you change? The authors and reviews provided the interview guide by all the research team before its application. An independent researcher (outside of this research team) with social-science background conducted the interviews, each of which lasted 30 min. Interviews were audio recording. The same person performed and transcribed the interviews. Analyses were performed by one of the researchers (BEA). Data were analyzed using thematic analysis (Fereday & Muir-Cochrane, 2006). Descriptive codes were used to summarize aspects related to three predefined themes: appropriateness, acceptability, and effectiveness of GPS (Proctor et al., 2011). With those themes in mind, we read the interviews, coded them, and identified other codes and themes. The qualitative software program, NVivo 12 (Nvivo, 2019) was used to facilitate coding and retrieving of data. In order to improve the trustworthiness of the analysis (Elo et al., 2014), we describe our sample thoroughly, including demographic, sexual and psychosocial characteristics. Two of the researchers (BEA and JLM) read the interviews and discussed relevance and meaning of results before sharing with other authors (Elo et al., 2014). Finally, quotations were used systematically to represent information that the participants provided. Translation of the interview extracts was performed by BEA, reviewed by an English editor, and then by another bilingual member of the team (BDA), in order to accurately represent the voices of participants. The checklist criteria for reporting qualitative studies as applied to the current study are presented in supplementary file (Tong et al., 2007).
Results
Sample
A total of 40 MSM living with HIV infection contacted the facilitator and were screened for GPS. Between June 2014 and May 2015, 11 MSM were eligible and provided baseline information. There were two groups of four participants each and one group with three participants. Of the 11, seven (63.3%) completed the intervention. The main reason for excluding potential participants was that they did not meet the “at least one CAS in the previous three months” criterion. The main reasons for not completing the program were related to work or other activities that conflicted with attendance.
Of the seven who finished the intervention, three had at least university education, four did not have their own income; four were on ART, and three reported detectable viral load at baseline; five used recreational drugs, including tobacco. Four of the participants were within first 2 years of diagnosis with HIV infection, two had been living with HIV infection for 3 years, and one for 7 years.
Adaptation of GPS
All participants in the adaptation session provided positive feedback about the order or sessions, the content, and the materials and exercises of the GPS program. The only changes suggested during the adaptation process were the inclusion of more role-play activities and information about the history of the LGTBQ rights movement in Colombia. The final number of sessions and a summary of the activities of the adapted GPS remained unchanged as per the original GPS and are presented in Table 2. The final GPS manual is available upon request from the first author.

Quantitative Findings
Figure 1 presents the results in terms of CAS. The number of participants engaging with different partners was variable throughout the study (see “total” in Fig. 1). However, after 3 months of the intervention, only one participant engaged in CAS with a casual HIV-unknown partner as opposed to three participants at baseline. In terms of psychosocial constructs at baseline (see Fig. 2a and b), five of the seven participants had a CES-D score 16 or more, suggesting high levels of depressive symptoms. Levels of loneliness, fear of rejection, and sensual sensation seeking were mild/moderate at baseline; the self-efficacy distribution was towards high levels; no one achieved the highest score at baseline. Most of the distributions overlapped across timepoints with variability in the experiences of participants. The median of depressive symptoms, fear of being rejected, and loneliness were lower in the follow-up than at baseline, while the self-efficacy scale median was higher in the follow-up than in the baseline, suggesting a possible gain in self-efficacy over time (Fig. 2a b).

Qualitative Findings
Of the seven participants who finished the intervention, six were interviewed. Table 3 presents themes and selected quotations from narratives of participants.
Themes and Quotations from Qualitative Interviews with Participants of GPS Intervention in Cali, Colombia.
Appropriateness
All six participants agreed that GPS was a program that was needed for MSM living with HIV infection. None of them had ever been exposed to a program like GPS and none had ever experienced being part of individual or group counseling. Participants mentioned the need to acquire knowledge on: prevention, avoiding alcohol and drug use, increasing their use of condoms, and acceptance of their diagnosis (see Table 3 for examples of narratives).
All participants perceived the group-based approach as useful. They recognized that the experiences of other participants facilitated their behavior change. Two participants recommended a bigger group and longer discussion to gain knowledge of other experiences. One participant offered a recommendation to create groups with participants of the same age. When participants were asked about aspects of the program that may not have worked for them, one participant stated that the program was too much about sex, “I felt uneasy because we talked too much about sex, sex, sex….” (MSM, under 12 years of education, 1 year living with HIV infection)”; and another stated that the program was too much about condoms.
One aspect of the project seemed not to meet participants needs. Participants reported that they do not have other friends living with HIV infection and felt isolated as PLWH. In this regard, participants reported they had the expectation of establishing friendships during the project. Participants indicated that having follow-up activities and additional meetings would have helped further to reduce their isolation.
Acceptability: All agreed that GPS was well designed. Subthemes included positive attitudes towards the materials and exercises, the knowledge and experience of facilitators, and the program structure. One participant offered suggestions about the materials, such as adding more audiovisual information and videos. Self-monitoring tools, such as the sexual diary to monitor change over time, was perceived as an important tool to encourage behavior change (see Table 3 for examples of narratives).
All the participants agreed that having a facilitator who lives with HIV infection was a positive aspect of the program. Narratives include that they were very knowledgeable about the prevention topics and about the intervention. Participants reported a good level of engagement and trust with the facilitators; they felt that having someone who understands their circumstances and who had lived through similar situations served as motivation to make changes.
Interestingly, despite the program running for 8 weeks with sessions of approximately 2 hr, there was no concern that the program was a burden timewise for participants. The participants instead thought that the program should be extended in terms of the time dedicated to each session and number of sessions. For all participants, continuing the program was important, especially if it was provided in the HIV clinic as part of routine care.
Effectiveness: The sexual goals participants wanted to achieve during GPS varied and included: using condoms; having a stable partner; reducing high-risk behaviors, such as alcohol or drug use; and increasing self-esteem. For all of them, either their goals were met or they were working to achieve them. Participants attributed changes in their sexual life to GPS (see Table 3 for examples of narratives). A common experience of most of the participants was gaining knowledge and confidence in protected sex, which is consistent with the quantitative findings. Participants attributed to GPS clear benefits in terms of identifying high-risk situations, such as reducing the use of apps, internet sites, going to saunas or clandestine sites, drug use and abuse of alcohol.
Discussion
In this study, we culturally adapted a Prevention with Positives intervention, GPS, in a high-priority population in Colombia. The adapted version for MSM in Colombia required minimal changes, mostly related to the need to have more audiovisual and role-playing exercises. We hypothesize that the minimal need for changes in GPS is partially due to the use of motivational interviewing, which allows each participant to identify his own personal motivations to achieve his sexual goals. As such, this adapted version of GPS was highly appropriate for the population for which it was adapted. Participants felt that the program was needed, was relevant for their lives, and helped them to make changes. Participants highlighted the fact that GPS was well designed, offered a safe space to talk, and was effective in helping them achieving their sexual goals. Our study identified that adequately trained Colombian peers could effectively deliver GPS to individuals in their communities: All informants perceived facilitators as skilled, knowledgeable, and helpful counselors. Participants highlighted the need for more audiovisual material for future implementation of GPS, the importance of continuity, longer exercise sessions, and the preference for groups of similar age composition.
To be consistent with other interventions in PLWH (Yin et al., 2014), we assessed the effects of GPS on CAS. The sample size rendered our study underpowered to detect statistical effects of GPS on CAS. At 3 months post-intervention, only one participant engaged in CAS with partners of unknown HIV status, the median levels of perception of self-efficacy were higher, and the median levels of depressive symptoms were lower. Depression affects 53% of patients attending the HIV clinic where participants were recruited (Mueses-Marin et al., 2019), and is highly prevalent in other MSM Latino living with HIV infection. Given the negative influence of depression in high-risk behaviors and adherence to antiretrovirals in PLWH (Mueses-Marin et al., 2019), these results show that GPS is promising for the sexual health of MSM living with HIV infection.
Various mechanisms could have contributed to those findings. First, all participants agreed that GPS provided knowledge on HIV prevention and other sexually transmitted diseases and this knowledge helped them make changes, consistent with the knowledge aspect of the IMB model (Cruess et al., 2018; Kalichman et al., 2008; Newcomb & Mustanski, 2013). Second, it is possible that the use of role-play scenarios facilitated maintenance or initiation of safer sexual practices (Kalichman et al., 2001). Third, MI has been associated with greater self-efficacy in PLWH: as the number of MI sessions increases (>131 min), the self-efficacy in safer sex increases (Chariyeva et al., 2012).
Importantly, we reported that peer interventions could be an effective way of delivery of information and counseling to Latino MSM, especially in PLWH. The group approach as well as the motivational interviewing format of GPS may have favored the discussion of sexual health with the facilitators (Golin et al., 2010). The training of peers in MI was feasible and they effectively delivered MI to participants. While other studies effectively used MI interventions for PLWH (Adamian et al., 2004; Naar-King et al., 2012) few have done so using peer facilitators (Hart et al., In Press). Due to issues around cost and sustainability of professional workers, peer-delivered behavioral MI interventions, including the GPS program (either attached to HIV clinics or in community organizations), therefore constitute appropriate alternatives to promote HIV prevention in Colombia and other Latin American settings.
Limitations
Our study is limited by our sample size. Our initial sample was 60, or 10 groups of six participants each, but it proved not possible to either recruit this sample nor to effectively schedule all participants for group sessions. We sought to recruit MSM with CAS in the previous 3 months, but only 27% of potential study respondents reported this. This means that implementation trials of GPS in Colombia will likely require sampling from several clinics around the country. Due to the small sample, we were not able to validate the Spanish translations of three of the psychosocial scales. Validated translations were not available at the time of our study. We measured participants using the same scales at each data point, which may underestimate the effects of the intervention over time. Finally, some of the criteria to establish trustworthiness of the qualitative data were not met in our study (Elo et al., 2014). We have included the perceptions of six of the seven participants who finished the intervention, and these experiences may not reflect the experience of those who did not complete the study or of other PLWH. Besides, our sample of PLWH may not reflect the social and behavioral characteristics of other MSM in Cali and other cities in Colombia (transferability). We have described the sample in different ways (credibility), and we know that the experiences of our participants are unique, as they have not received any other intervention during the time the study was conducted (dependability).
Conclusions
Overall, GPS is a community-based intervention that has the potential to reduce risky behaviors in PLWH, improve self-efficacy in negotiation of condom use, and decrease depressive symptoms. Given the lack in Colombia and the scarcity in other Latin American interventions to improve the sexual health of MSM living with HIV infection (Maiorana et al., 2016; Vu et al., 2015), our study suggests that GPS can potentially fill this gap. Including an intervention as part of the care in HIV clinics would be beneficial for HIV prevention and improving the quality of life of MS who live with HIV. Future evaluations of the effect and implementation of GPS in other Latino MSM community settings are needed.
