Background. During the last two decades, the change from custodial care provided by large institutions to community-focused services made considerable progress in Germany. However, nothing is known about how this is reflected in the public's acceptance of community psychiatry services. Methods. The study is based on data from two population surveys among German citizens aged 18 years and over, living in the 'old' German States. The first was conducted in 1990 (n = 3067), the second in 2011 (n = 2416). With the help of identical questions, respondents' attitudes towards psychiatric units at general hospitals and group homes for mentally ill people were assessed. Results. While the proportion of the public that explicitly welcomed establishing psychiatric units at general hospitals and opening group homes for mentally ill people decreased, the proportion of those who reacted with indifference increased. The proportion of the German population that explicitly rejected the implementation of these services remained unchanged. Conclusions. While community psychiatry services expanded considerably over the last few years, the public's attitude towards them has not changed substantially.
