Digital Interventions for Relapse Prevention in Adolescence

Some adolescents experience periods of anxiety and/or depression, and some find that these periods return over time. The purpose of this study is to examine whether digital interventions-where individuals work systematically with their own thoughts and feelings during periods when they feel well-can help them maintain well-being for longer. The study includes adolescents aged 16-19 who have previously experienced episodes of depression and/or anxiety to a degree that led them to seek help (e.g., from a school nurse, general practitioner, health clinic, or child and adolescent mental health service). Through a research app on their smartphones, participants complete tasks and answer questionnaires. The study is fully digital. Some participants meet with a therapist in digital group sessions, while others work independently with the digital content. We will also examine the cost-benefit aspects of offering such interventions. If the study achieves its goals, digital interventions may eventually become a service offered to adolescents recovering from depression and anxiety.
