Current research suggests that mental health in young people is declining. Recent data indicate that depressive disorders are the main cause of morbidity among 15-19 year-olds, followed by anxiety disorders. In Switzerland, prevalence rates for depression range between 9.7% and 23.9% for females and from 3.6% to 12.9% for males, while for anxiety, it oscillates between 13.6% and 17.3% for females and 9.1% and 12.5% for males, depending on the type of sample, the age group, and the screening instrument used.
The objectives of this research are: (1) To assess the prevalence of mental health disorders (depression and/or anxiety) among adolescents (14-19 year-olds) in Switzerland and Liechtenstein; (2) To identify individual, family, social and environmental factors associated to these disorders.
