Study summary

The purpose of the Mental Health in Austrian Teenagers (MHAT) - Study is to collect the first epidemiological data on mental health and psychiatric disorders in a representative sample of Austrian adolescents between 10 and 18 years.

Read the detailed description

Knowing about the prevalence of psychiatric disorders and related risk and protective factors is essential for the development of prevention programs and therapeutic approaches. Up to now, no epidemiological data on prevalence rates of psychiatric disorders and related risk and protective factors based on a representative sample is available for Austrian adolescents.

The aim of the study is to present rates of behavioral, emotional and social problems as well as prevalence rates of mental disorders. Furthermore the investigators want to examine risk factors, protective factors and quality of life in a large sample of adolescents aged 10 to 18 years. A two step design is chosen for this purpose to obtain diagnoses based on the Diagnostic and Statistical Manual of the American Psychiatric Association, Version 5 (DSM-5):

  1. Phase 1 (screening) is a screening for emotional, behavioral and social problems as well as social and demographic correlates, risk and protective factors and quality of life.
  2. Phase 2 (interviews) includes structured diagnostic interviews to assess psychiatric diagnoses according to DSM-5 criteria with adolescents above a predefined cut-off score in the screening, and a random sample of adolescents scoring below the cut-off.
