PRIMARY outcome
Timeframe: Through study recruitment and study completion, an average of five monthsPopulation: Targets and Partners were analyzed separately. Thus, the total number of participants is 2x the number of targets and partners.
Participant subjective ratings of the benefits and costs of participating in the study. Tolerability was defined using eight items assessing the accessibility, benefits, and costs of the study scored on a 1 (strongly disagree) to 7 (strongly agree) scale. Tolerability scores were separated by target and partner and reported by condition.
