Plain English Summary

Background and study aims
The PREPARE Project is a study among adolescents in Cape Town (South Africa) which aims to prevent HIV and intimate partner violence (IPV). The project aims to develop, implement and evaluate a comprehensive school-based HIV and IPV prevention programme. The study's findings will help to improve adolescent health and inform the development of school adolescent health policies.

Who can participate?
Boys and girls in Grade 8 attending public high schools in the Western Cape Province. We will recruit between 3000 and 4000 adolescents. The students will be from 42 high schools in the Western Cape Province. No specific exclusion criteria will be used.

What does the study involve?
PREPARE is a school-based HIV and violence prevention programme. Half of the schools have been randomly allocated to receive the intervention in 2013, and the other half will serve as control schools. Participants will complete a questionnaire in February- March 2013 before the intervention. They will complete questionnaires again at the completion of the intervention six months later (August-September 2013, and in February-March 2014.
The intervention consists of 4 components:
1. After-school clubs to prevent sexual risk behavior and partner violence and to promote healthy relationships;
2. A school-based health service;
3. Local police officers’ involvement in a school safety programme;
4. A photography project to involve students in improving the school safety programme.
The primary outcomes are: 1. Sexual debut; 2. Number of partners; 3. Consistent use of condoms.
Secondary outcomes are 1. Live births and terminations of pregnancy among female participants, as counts per school, over a three year time period; 2. Intimate partner violence perpetration and victimization.

What are the possible benefits and risks of participating?
There will be no immediate or direct benefits to participants. We hope that the results will influence policy makers, leading to benefits on a larger scale.
There is little potential risk associated with participation. It is possible that some questions in the questionnaire may make students feel uncomfortable or emotional. Research staff will be trained to manage these students or refer them for professional help.

Where is the study run from?
The University of Cape Town, Department of Psychiatry and Mental Health, Adolescent Health Research Unit (South Africa).

When is the study starting and how long is it expected to run for?
The schools were recruited in 2012 and recruitment of students will start with the new school year, in January 2013. Students will be enrolled in the study for 12-14 months. Live births and terminations of pregnancy as counts per school among female participants will be measured 3 years after the programme is completed, using health service records.

Who is funding the study?
The PREPARE study is funded by the EC Health research program (under the 7th Framework Program). Grant Agreement number 241945.

Preventing sexual risk behavior and intimate partner violence among adolescents in Cape Town


PREPARE project

Study hypothesis

The intervention will impact on students’ behavior. We hypothesize that the study will lead to:
1. An increase of the age of participants' sexual debut
2. A decrease of participants' number of partners
3. An increase of consistent use of condoms among participants

The schools in the intervention arm of the study will receive the intervention, consisting of 4 parts, in 2013. Students in comparison schools will benefit from a delayed intervention programme. One year later, students in these schools will get access to the same materials and teachers, nurses and other staff will receive the same kind of training as was provided for intervention schools.

The intervention comprises four parts and will take place over a period of 5-6 months:
1. A programme of sessions delivered by trained facilitators in after-school clubs on the school premises. The programme aims to prevent intimate partner violence and promote healthy relationships among adolescents. The programme will be conducted over approximately 10-15 afternoons, covering one or two sessions each afternoon, delivered by a trained facilitator. In addition, one session will be delivered by police officers and one by health workers. The sessions are focused on healthy relationships and prevention of HIV and IPV.
2. A school-based preventive health service delivered by a service provider who will provide one drop-in for one and a half hours every week during academic term times in each of the intervention schools. The service will be offered in the afternoons after school has ended, between the hours of 2:30 and 4:00. The service will be primarily available for Grade 8 students in our sample who will be offered an appointment at the service and will be prioritized in service provision. However the service will also be available to all year groups (12 to 20 year olds) who attend the schools.
3. The involvement of local police officers in school safety, to fulfil three responsibilities: crime prevention, education related to violence prevention and the law, and mentoring for those exposed to violence. The police offers will be available at the school at least one afternoon per week to fulfill their educational and mentoring responsibilities. In addition, they will be available for the school at times arranged between them and the school safety committee.
4. A Photovoice project, consisting of 8 sessions, to involve students in improving the safety of their school environment, conducted after school hours on the school premises.
