In this master thesis the relationship between outpatient mental health services and regional suicide rates in Austria from 2001 to 2009 was examined in a cross-sectional analysis. The present thesis arose in the context of the study "Suicides in Styria 2005-2009" commissioned by the State of Styria under the direction of Carlos Watzka.The following were selected as indicators of the outpatient mental health services: the rate of staff working in outpatient mental health centers, crisis intervention centers and mobile psychiatric care, the length of time outpatient mental health facilities have existed in the district, as well as the rate of psychotherapists and psychiatrists. These indicators were then compared in bivariate and multivariate analysis in relation to the raw and age-standardized suicide rates according to district. In multiple linear regression models also demographic, socio-economic and ecological parameters were included.An early founding year of outpatient mental health facilities in the district and a high rate of psychiatrists and psychotherapists were associated with lower suicide rates. After including the socio-economic, demographic and ecological control variables in the multivariate model, these correlations decreased slightly, but remained existent. With regard to the rate of staff working in outpatient mental health centers or similar facilities no correlation with the regional suicide rates showed.Although a good availability of outpatient mental health care is not the only reason for low suicide rates, the prevention of suicides should focus its efforts on increasing the availability of these services, especially in rural areas.
