Diagnostic Survey of Mental and Substance Use Disorders Among Norwegian College and University Students

Study Overview
=================
Brief Summary
-----------------
The aims of this observational survey are to 1) collect data on the prevalence of mental and substance use disorders, and 2) investigate risk factors and consequences of mental and substance use disorder

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.
