Another important step in some adaptations has been to have local educational and/or psychological professionals review intervention materials and provide detailed feedback on the developmental appropriateness of the content for a particular age group or clinical population. This was particularly relevant when adapting the Preventure Programme for youth in London, UK and Montreal, in which the goal of the study was to test the impact to the programme for younger cohorts than in previous trials in order to demonstrate prevention of substance use onset. The recent Montreal and Australian adaptations [51] were also reviewed by experienced editors of children’s literature to be sure that the intervention material, particularly the scenarios, is written in a way that is engaging for readers of that age.
