Integrated Prevention of HIV Risk and Intimate Partner Violence Among Adolescents in South Africa

Satisfaction with intervention content is based off of a measure called the Client Satisfaction Questionnaire developed by Larsen DL, Attkisson CC, Hargreaves WA, Nguyen TD. Assessment of client/patient satisfaction: Development of a general scale. Evaluation and Program Planning. 1979;2:197-207.

We focus on the question from that scale that assesses satisfaction with the program. The item asks, "How satisfied are you with the program you have received?" Participants could rank their satisfaction from: 1 = quite dissatisfied, 2 = mildly dissatisfied, 3 = mostly satisfied, 4 = very satisfied." Higher scores correspond with higher satisfaction with the intervention program.

Feasibility is measured by ability to recruit the planned number of participants into the trial. We wanted to recruit at least 95% of the target number of planned participants.

Feasibility is also measured by retention of trial participants at the final timepoint. A cut off of 75% retention of all participants enrolled in the trial at the final timepoint is viewed as a good result for feasibility.

Fidelity was not based off a published measure. Rather, a neutral observer rated the facilitator's delivery skills and adherence to a manualized protocol for delivering the intervention that guided the consistent delivery of core theoretical components of the intervention. This neutral observer used the following rankings on a scale with rankings ranging from 1 (equating to a category labeled as low demonstration of skills, <25% of the time) to 3 (equating to a category labeled as high demonstration of skills, >75% of the time). An average ranking of 2.5 or more is seen as success for fidelity.

Measured by comparing whether % of those who refused sex at 6 months versus baseline.

Measured by examining whether the prevalence of those engaging in intimate partner violence (forced vaginal sex) was significantly lower at 6 months as compared to baseline.

The likelihood of engaging as an active bystander to stop violence is measured through the Bystander Behavior Scale, ranging from 1-40. The questions are answered on a 5-point Likert scale, ranging from 5 = "Very unlikely" to 1 = "Very likely". Lower scores correspond to more likelihood of intervening as an active bystander to stop violence, a measure developed by Miller E, Tancredi DJ, McCauley HL, Decker MR, Virata MCD, Anderson HA, et al.
