The present study investigated the prevalence of psychological distress in medical and psychology students ( n= 293) at a German University. Sampling structure, questionnaire and process of this study were a reproduction of a prior study carried out at the same university in 1994 ( n=346) which allowed for assessing changes over time. Results show that 12% of students suffered from clinically relevant psychological complaints. Compared to 1994, self-reported mental health problems have significantly decreased. Possible explanations such as an improvement of health care, economic conditions and study conditions are discussed.
