Study characteristics
Methods	Study design: RCT Duration of study: the study was conducted from 2003 to 2004. Country: Mauritius Income classification: upper‐middle‐income country in 2003‐2004 Geographical scope: urban Healthcare setting: public schools
Participants	1. Age: from 12 to 16 years 2. Gender: both 3. Socioeconomic background: almost all participants lived with their nuclear families, and the majority had at least one parent employed on a full‐time basis. 4. Educational background: single‐sex secondary public schools in Mauritius Inclusion criteria: all students in Years 7 and 9 at two single‐sex schools were invited to participate. Exclusion criteria: there were no specified exclusion criteria. Note: at baseline, the intervention and control group scores for Reynolds Adolescent Depression Scale‐2 (RADS‐2) were, respectively, 51.81 (9.07) and 50.61 (9.70). Stated purpose: to assess the efficacy of a universal prevention programme for adolescent depression implemented by school teachers in Mauritius.
Interventions	Name: RAP‐A programme Title/name of PW and number: eight programme facilitators (teachers) 1. Selection: experienced teachers (six females, two males), four from each school 2. Educational background: not specified 3. Training: facilitators attended a 2‐day training workshop involving 16 hours of training conducted by one of the research team who was a certified RAP trainer; this trainer also provided ongoing support for the teachers when required. The training workshop involved: 1) information on adolescent mental health, and specifically adolescent depression; 2) theory underlying the programme; 3) programme content and implementation techniques. 4. Supervision: to maintain programme integrity, one half‐day booster training session was organized 6 months following initial training. 5. Incentives/remuneration: not specified Prevention type: universal – all students in years 7‐9 in the selected schools were eligible for inclusion, and their baseline scores for the RADS were well below the cut‐off for the measure. In addition, the authors defined the intervention as “a universal prevention program for adolescent depression”. Intervention details: the RAP‐A programme is a manualized group treatment programme developed by Shochet, Holland, and Whitefield (Shochet 1997a; Shochet 1997b). It involved 11 one‐hour weekly sessions with 8 to 12 participants per group. It included both cognitive‐behavioural and interpersonal approaches covering topics such as building self‐esteem, keeping calm, self‐talk, thinking resourcefully, problem‐solving, identifying and accessing support networks, considering the perspective of others, and keeping the peace. To maintain programme integrity, the programme was delivered in English, and the overall structure and content of the programme were unchanged. The cultural relevance of the programme was discussed with the programme facilitators (teachers), and their feedback indicated that no changes were required to the programme. Control: waiting list
