Overview
Brief Summary
The purpose of this study is develop and pilot test a personalized HIV intervention with youth experiencing homelessness by creating and field testing prevention messages that address real-time predictors (e.g., sexual urge, use to use drugs, and substance use) of HIV risk behaviors,to evaluate the feasibility and acceptability of the intervention and to evaluate the intervention outcome effects on HIV risk behaviors (e.g., condomless sex, number of sexual partners, pre-exposure prophylaxis(PrEP) awareness, substance use during sex,Intravenous(IV)drug use)

Outcomes
Primary Outcomes
Effect on HIV risk as assessed by number of sexual partners
Time Frame: 6 weeks
Feasibility as assessed by number of participants who complete the study
Time Frame: 6 weeks
Feasibility as assessed by number recruited
Time Frame: baseline
Number recruited is number of eligible youth minus number who refuse to participate.
Feasibility as assessed by number of staff hours required
Time Frame: 6 weeks
Acceptability as assessed by score on the Mobile App Rating Scale (MARS)
Time Frame: 6 weeks
The Mobile App Rating Scale (MARS) consists of 23 items on a 5-point (1-5) scale is designed to score apps on the criteria of engagement, functionality, aesthetics, and information quality (sub-scales). Total score is determined by calculating the mean of each sub-scale and an overall mean score. High mean scores indicate a higher quality app.
Number of participants who complete greater than 80% of the Ecological Momentary Assessments (EMAs)
Time Frame: 6 weeks
Acceptability as assessed by score on the System Usability Scale (SUS)
Time Frame: 6 weeks
The System Usability Scale (SUS) consists of 10 items on a 5-point (0-4) Likert scale and is designed to assess acceptability of a product. Overall score ranges from 0 to 100, with higher scores indicating greater acceptability.
Feasibility as assessed by number of participants who damage or lose phones
Time Frame: 6 weeks
Effect on HIV risk behaviors as assessed by number of participants who use condoms
Time Frame: 6 weeks
Number of participants who read greater than 80% of Just-In-Time Adaptive Intervention (JITAI) messages
Time Frame: 6 weeks
Effect on HIV risk as assessed by number who use substances before sex
Time Frame: 6 weeks
Effect on HIV risk as assessed by number of participants who have pre-exposure prophylaxis (PrEP) interest
Time Frame: 6 weeks
Effect on HIV risk as assessed by number of participants who undergo HIV or sexually transmitted infection (STI) testing
Time Frame: 6 weeks
