Background Mobile technologies are a useful platform for the delivery of health behavior interventions. Yet little work has been done to create a rigorous and standardized process for the design of mobile health (mHealth) apps. This project sought to explore the use of the Information Systems Research (ISR) framework as guide for the design of mHealth apps. Methods Our work was guided by the ISR framework which is comprised of 3 cycles: Relevance, Rigor and Design. In the Relevance cycle, we conducted 5 focus groups with 33 targeted end-users. In the Rigor cycle, we performed a review to identify technology-based interventions for meeting the health prevention needs of our target population. In the ISR Design Cycle, we employed usability evaluation methods to iteratively develop and refine mock-ups for a mHealth app. Results Through an iterative process, we identified barriers and facilitators to the use of mHealth technology for HIV prevention for high-risk MSM, developed ‘use cases’ and identified relevant functional content and features for inclusion in a design document to guide future app development. Findings from our work support the use of the ISR framework as a guide for designing future mHealth apps. Discussion Results from this work provide detailed descriptions of the user-centered design and system development and have heuristic value for those venturing into the area of technology-based intervention work. Findings from this study support the use of the ISR framework as a guide for future mobile health (mHealth) app development. Conclusion Use of the ISR framework is a potentially useful approach for the design of a mobile app that incorporates end-users’ design preferences.

Episodic drug use and binge drinking are associated with HIV risk among substance-using men who have sex with men (SUMSM), yet no evidence-based interventions exist for these men. We adapted personalized cognitive counseling (PCC) to address self-justifications for high-risk sex among HIV-negative, episodic SUMSM, then randomized men to PCC (n = 162) with HIV testing or control (n = 164) with HIV testing alone. No significant between-group differences were found in the three primary study outcomes: number of unprotected anal intercourse events (UAI), number of UAI partners, and UAI with three most recent non-primary partners. In a planned subgroup analysis of non-substance dependent men, there were significant reductions in UAI with most recent non-primary partners among PCC participants (RR = 0.56; 95 %CI 0.34–0.92; P = 0.02). We did not find evidence that PCC reduced sexual risk behaviors overall, but observed significant reductions in UAI events among non-dependent SUMSM. PCC may be beneficial among SUMSM screening negative for substance dependence.

Background Few HIV/STI interventions exist for African American adolescent girls in juvenile detention. Objective The objective was to evaluate the efficacy of an intervention to reduce incident STIs, improve HIV-preventive behaviors, and enhance psychosocial outcomes. Methods We conducted a randomized controlled trial among African American adolescent girls (13-17 years, N=188) in juvenile detention from March 2011 to May 2012. Assessments occurred at baseline and 3- and 6-months post-randomization and included: audio computer-assisted self-interview, condom skills assessment, and self-collected vaginal swab to detect Chlamydia and gonorrhea. Intervention The Imara intervention included three individual-level sessions and four phone sessions; expedited partner therapy was offered to STI-positive adolescents. The comparison group received the usual care provided by the detention center: STI testing, treatment and counseling. Results At the 6-month assessment (3-months post-intervention) Imara participants reported higher condom use self-efficacy (p<0.001), HIV/STI knowledge (p<0.001), and condom use skills (p<0.001) compared to control participants. No significant differences were observed between trial conditions in incident Chlamydia or gonorrhea infections, condom use, or number of vaginal sex partners. Conclusions Imara for detained African American adolescent girls can improve condom use skills and psychosocial outcomes; however, a critical need for interventions to reduce sexual risk remains.
