PNF RCT to Decrease Alcohol Use and Increase HIV Prevention

Summary

Randomized controlled trial to test the preliminary efficacy and mediating mechanism of a personalized normative feedback intervention on behavioral intentions, heavy alcohol use, and HIV/STI prevention among adolescents and young adults in Rwampara District, Uganda.

Conditions

• HIV (Human Immunodeficiency Virus)
• Alcohol Misuse
• STI

Interventions

BEHAVIORAL

PNF - HIV norms

As this is a survey experiment, the "intervention" involves random assignment to a survey questionnaire with specific treatments. This treatment is a survey-based questionnaire with a prompt stating the participant's previously provided estimate of engagement in HIV-transmission behavior engagement in their school. Participants are then provided with the true rates of HIV-transmission behavior engagement in their school, and notification that this is consistent across demographic groups. Two follow-up waves of survey collection over the 12 months following the PNF will collect information about engagement in HIV/STI transmission and prevention behaviors and alcohol misuse, which will be compared to baseline data collected before treatment.

BEHAVIORAL

PNF - Alcohol use norms

As this is a survey experiment, the "intervention" involves random assignment to a survey questionnaire with specific treatments. This treatment is a survey-based questionnaire with a prompt stating the participant's previously provided estimate of rates of alcohol use in their school. Participants are then provided with information about the true rates of alcohol use in their school. Two follow-up waves of survey collection over the 12 months following the PNF will collect information about engagement in HIV/STI transmission and prevention behaviors and alcohol use, which will be compared to baseline data collected before treatment.

BEHAVIORAL

PNF - HIV and alcohol use norms

As this is a survey experiment, the "intervention" involves random assignment to a survey questionnaire with specific treatments. The fourth treatment is a survey-based questionnaire with a prompt stating the participant's previously provided estimate of HIV transmission behavior engagement and alcohol use in their school. Participants are then provided with information about the true rates of both HIV transmission behavior engagement and alcohol use in their school. Two follow-up waves of survey collection over the 12 months following the PNF will collect information about engagement in HIV/STI transmission and prevention behaviors and alcohol use, which will be compared to baseline data collected before treatment.
