Reducing HIV in Adolescents (RHIVA)

• HIV-incidence rates [ Time Frame: annually, after every 12 months of follow up ] [ Designated as safety issue: No ]
  To evaluate the efficacy of a cash-incentivised prevention intervention in reducing HIV-incidence rates in high-school learners
  
  

• Academic performance measured as an overall passing grade (50%) [ Time Frame: 6 monthly ] [ Designated as safety issue: No ]
  To support learners improving academic performance, attend school, complete schooling and improve their self-esteem, learners will be incentivised to pass their June and November examinations, with a minimum of a 50% average. Educators from the selected schools will design, administer and mark the June and November examination papers.
  
  
• voluntary uptake of HIV testing [ Time Frame: annually, after every 12 months of follow up ] [ Designated as safety issue: No ]
  Learners must provide the receipt from the clinic that specifies that the learner was tested for HIV.
  
  
• Substance use patterns [ Time Frame: annually, after every 12 months of follow up ] [ Designated as safety issue: No ]
  Urine specimens will be utilised for testing for the presence of recreational drugs.
  
  
• Pregnancy rates in female learners [ Time Frame: annually, after every 12 months of follow up ] [ Designated as safety issue: No ]
  A dipstick pregnancy test will be performed on the urine sample of all female learners at baseline and at the two annual follow-up visits.
  
  
• Contraceptive use patterns in female learners [ Time Frame: annually, after every 12 months of follow up ] [ Designated as safety issue: No ]
  Annual behavioural questionnaires will monitor self-reported contraceptive use.
  
  
• Participation in extra-curricular activities [ Time Frame: annually, after every 12 months of follow up ] [ Designated as safety issue: No ]
  Attendance and participation in a life skills/sustainable livelihoods programme will be assessed. Self-reported participation in extra-curricular activities will be assessed in annual behavioural questionnaires.
  
  
• HIV risk reduction behaviour [ Time Frame: Annually, after every 12 months of follow up ] [ Designated as safety issue: No ]

  The following will be assessed through a self-reported questionnaire:

  condom use; primary and/or secondary sexual abstinence rates; sexually transmitted disease rates intergenerational sexual coupling (age of sexual partner(s)) age of sexual debut; frequency of HIV testing; number of concurrent sex partners; frequency of partner change; medical male circumcision rates; anal sex rates

  
  

The impact of the cash incentivised intervention will be assessed using a matched pair, cluster randomised controlled trial design. The 14 selected high schools in the Vulindlela School Circuit will be matched in pairs. The matched pairs of schools will be the unit of randomisation. Baseline measurements, using a standardised tool (structured questionnaire and biological specimens) will be undertaken simultaneously in each matched pair and will include all eligibly enrolled and consenting learners in the respective schools. On completion of baseline measurements in each matched pair of schools, the randomisation code for the pair will be revealed and the intervention will be implemented in the intervention school. All schools will receive the same prevention intervention but only the intervention school will receive the cash incentives. Follow-up measurements will be undertaken approximately 12 and 24 months after implementation of the intervention using a similar standardised assessment tool to that used at baseline. At baseline and during follow-up assessments in intervention and control schools, linked HIV and substance use testing will be undertaken in all learners and pregnancy testing in female learners. Other secondary endpoints will be assessed using a structured questionnaire.
