[German version of the Snaith-Hamilton-Pleasure Scale (SHAPS-D). Anhedonia in schizophrenic and depressive patients].

The Snaith-Hamilton-Pleasure-Scale (SHAPS), introduced in English in 1995, assesses self-reported anhedonia in psychiatric patients. It has proven psychometric properties and advantages in applicability compared to other instruments assessing anhedonia. This study presents results of a systematic transcultural protocol translating the SHAPS into German (SHAPS-D). Quality of translation was confirmed on the one hand by bilingual reviewers with regard to equivalence in content and tone. On the other hand stable results were found in a test-retest-design crossing the English and German version with bilingual persons. SHAPS-D was obtained from schizophrenic (n = 50) and depressive (n = 33) patients and from healthy controls (n = 67). Results on applicability, internal consistency and relationship to depression, subjective quality of life, well-being as well as psychopathology indicate that the SHAPS-D is a useful and promising instrument in assessing anhedonia.
