“…54 Available evidence suggests that interview-rated Anhedonia-Asociality is not significantly related to indices of general intellectual ability or generalized cognitive impairments. There is some evidence of moderate relationships between anhedonia and measures of executive or frontally mediated cognitive functions, 55,56 as well as frontal functional 57,58 and structural abnormalities. 59,60 No consistent patterns have emerged for other specific aspects of neurocognition.…”

Anhedonia, the diminished capacity to experience pleasant emotions, is a common, treatment-resistant feature of schizophrenia that is often included among the negative symptoms of this disorder. This selective review describes the 3 most commonly used approaches to assess anhedonia in schizophrenia: interview-based measures, self-report trait questionnaires, and laboratory-based assessments of emotional experience. For each assessment approach, psychometric properties, relationships to other symptoms and features of schizophrenia, and relationships with the other assessment approaches are evaluated. It is concluded that anhedonia can be reliably assessed and constitutes a distinctive, clinically important aspect of schizophrenia that should be included in a comprehensive evaluation of negative symptoms. Current efforts to define more precisely the nature of the hedonic deficit in schizophrenia are discussed, and recommendations for optimal assessment of anhedonia in clinical trials of novel treatments for negative symptoms are provided.

“…Krankhcitsphase (akut vs. remittiert), Alter und Geschlecht nicht vergleichbar sind. Es gibt auch nur wenige Untersuchungen über ereigniskorrelierte Potentiale und Psychopathologie bei schizophrenen Patienten, in denen cinc Unterteilung der psychopathologischen Phänomene in Positiv-und Negativsymptome, und bei letzteren wiederum in primäre und sekundäre Negativ-Symptome, vorgenommen wird (8,19,20,46). Gerade diese Unterteilung erscheint aber als klinisch relevant und gewinnt in den letzten Jahren zunehmend an Bedeutung.…”
