Summary:

Detailed description: 
      This project focuses on mental health, quality of life and alcohol and substance use in
      students pursuing higher education. The targeted population, all Norwegian college and
      university students, are in an important and vulnerable period of life transitions. The
      overall aim of the current project is two-fold: First, the investigators will conduct a
      clinical assessment of mental disorders by using the newly developed electronic version of
      the World Health Organization (WHO) Composite International Diagnostic Interview, fifth
      version (CIDI 5.0), developed for the WHO World Mental Health Surveys. CIDI 5.0 is a
      standardized interview assessing 30-days,12 months and lifetime prevalence for several mental
      and substance use disorders according to diagnostic criteria in the Diagnostic and
      Statistical Manual of Mental Disorders 5th edition (DSM-5) and International Classification
      of Diseases 10th edition (ICD-10). The overall aim of this will be to obtain accurate
      prevalence rates of disorders, as well as to validate and compare the briefer instrument used
      in the Students' Health and Wellbeing Study (SHOT), including the Hopkins Symptom
      Checklist-25 (HSCL-25). Second, the investigators will examine risk factors based on data
      from the SHoT, which is one of the world's largest epidemiological studies of student health.

Study population: 
        The base study population of the current study stem from the SHoT 2022 study, a large
        national survey of students enrolled in higher education in Norway. The SHoT 2022 was a
        comprehensive survey of several domains of mental health and lifestyle factors, distributed
        electronically through a web-based platform. In short, SHoT 2022 was conducted between
        February 8 and April 19, 2022, and invited all full-time Norwegian students pursuing higher
        education. In all, 169,572 students fulfilled the inclusion criteria, of whom 59,544
        students completed the online questionnaires, yielding a response rate of 35.1%.

        When consenting to participate in the SHOT2022, the students were also asked to indicate if
        they wished be invited to a follow-up study of mental disorders, of whom 26,311 consented.
