NameTimeMethod
Effect on HIV risk as assessed by number of sexual partners6 weeks
Feasibility as assessed by number of participants who complete the study6 weeks
Feasibility as assessed by number recruitedbaseline

Number recruited is number of eligible youth minus number who refuse to participate.

Feasibility as assessed by number of staff hours required6 weeks
Acceptability as assessed by score on the Mobile App Rating Scale (MARS)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)6 weeks
Feasibility as assessed by number of participants who damage or lose phones6 weeks
Effect on HIV risk behaviors as assessed by number of participants who use condoms6 weeks
Acceptability as assessed by score on the System Usability Scale (SUS)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.
