About this study

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.

Primary outcomes

  1. Change in WHO-5 (WHO-Five Well-being Index)

    Time frame: Change from baseline to six weeks after intervention.

    WHO-5 (WHO, 1998): A five item self-report questionnaire assessing well-being on a six point scale.

  2. Change in SDQ (Strengths and Difficulties Questionnaire)

    Time frame: Change from baseline to six weeks after intervention.

    SDQ (Goodman, 1997): A 25 item self-report assessing mental health and psychosocial functioning in 11-17 years old adolescents on a three point scale.

Secondary outcomes

  1. General Self-efficacy scale (GSE)

    Time frame: Change from baseline to six weeks after intervention.

    Resilience will be measured with the Norwegian version of the GSE (Røysamb, 1997; Schwarzer et al., 1995) which consists of 10 questions measured on a four-point scale.

  2. Help-seeking behavior

    Time frame: Change from baseline to six weeks after intervention.

    Two self-report items measuring if they sought help and who they sought help from.

  3. Self-liking and Competence Scale

    Time frame: Change from baseline to six weeks after intervention.

    Self-liking and Competence Scale (Silvera, Neilands, & Perry, 2001; Tafarodi & Swann, 2001): A 20 item self-report assessing self-liking and self-competence.

  4. Sleeping quality
