Brief report: A qualitative evidence synthesis of the psychological processes of school-based expressive writing interventions with adolescents

However, these conclusions are still preliminary because of the paucity of the qualitative evidence found, both in quantity and quality. We recommend that more rigorous and in-depth qualitative research be undertaken to: 1) explore adolescents' subjective experience about the expressive writing intervention, using in-depth individual interviews; 2) thoroughly assess the content of students' texts written during the intervention; and 3) document the process of expressive writing interventions through observational methods. The results of such investigations would support the development and implementation of school-based expressive writing-type of interventions adapted to adolescents.
