Greek financial crisis has incurred adverse effects on the mental health of the population; however existing research is constrained in the adult population. Therefore, the present study aims to shed light on the mental health state of adolescents during the recession. In this context 2,150 adolescents were recruited from a random and representative sample of public and private schools in the greater Athens area. Mental health problems were assessed with the selfreport Strengths and Difficulties Questionnaire while additional questions enquired about students' socio-demographic characteristics. Findings indicate that roughly one out of ten adolescents scored above the cut off point for the total difficulties score, with the higher prevalence been recorded for the conduct problems sub-scale. More specifically, 7.7% of the sample scored above the abnormal cut-off point for the total difficulties score, 10.9% for emotional symptoms, 11.9% for conduct problems, 10.6% for hyperactivity and 4.8% for peer problems. Furthermore, adolescents who reported that during the previous month there was not enough food in their house displayed higher odds of manifesting mental health problems than adolescents who replied negatively in the particular query. On the grounds of these results, there is indication about the adverse effects of the financial crisis in the development of psychiatric symptomatology in adolescents in the Greek society. This is the first study providing epidemiological data on the current state of adolescents' mental health amid the recession in Greece, showing that the crisis impinges disproportionately on the most vulnerable socio-economic groups.
