Opp - a Universal Mental Health Promoting Mobile Application for Adolescents

Study Overview
=================
Brief Summary
-----------------
The aim of the project is firstly, to develop an app-based mental health intervention for adolescents. Secondly, to evaluate the effect of this app. The overarching goal is to offer a low-threshold intervention, called Opp, that is easily accessible and free to use for all adolescents in Norway.

Detailed Description
-----------------
The intervention Opp will be delivered through a mobile application. The overall goals of Opp are to 1) increase well-being and mental well-being, 2) increase knowledge about mental health, 3) increase coping skills to deal with stress, 4) increase help-seeking behavior, 5) increase self-esteem, 6) increase sleep quality and 7) reduce mental health problems. To evaluate the mobile application two studies will be conducted: A user survey and an effectiveness study with a follow-up examination after about six weeks. The effectiveness study will be conducted as a randomized controlled trial with an intervention group and a waiting-list control group.
