[Methodology of psychiatric case histories]

This paper deals with the methodology of psychiatric case histories. Three types of case histories are differentiated. The didactic case history teaches about the typical aspects of a psychiatric disorder or treatment by using an individual patient as an example. In the heuristic case history the individual case gives rise to challenging established concepts or to generate new hypotheses. Such hypotheses drawn from inductive reasoning have then to be tested using representative samples. The focus of hermeneutic case histories is the significance of pathological behaviour and experience in the context of the biography of an individual patient. So-called psychopathographies of important historical figures can also be differentiated according to these types. Based on these methodological considerations, quality standards for the named types of case histories are stated.
