Aim of the study: For the 11th revision of the International Classification of Diseases and Related Health Problems (ICD-11) attitudes of psychologists towards classificatory diagnostics should be considered.
Method: A survey was conducted via the Internet in 22 countries. 1985 psychologists participated with N=170 from Germany and N=37 from Switzerland.
Results: The German participants preferred the ICD. Classificatory diagnostics should inform on treatment as well as serve for communication. The majority argued for a flexible use and guidance towards strict criteria. In contrast to respondents from other countries, a functional status as part of the diagnostic criteria was not considered but in line with them, a dimensional component was endorsed.
Conclusion: Responses of the German psychologists partially differ to those of participants from other countries. Differences and implications are discussed.
