Trait Anhedonia in Schizophrenia: A Systematic Review and Comparative Meta-analysis.

ABSTRACT: Anhedonia, the reduced capacity to experience pleasure, has long been considered a prominent feature of schizophrenia spectrum disorders. Many domain-specific conceptualizations of anhedonia and pleasure capacity have been developed, and there currently exist a variety of self-report assessment tools that purport to assess these various domains. The current systematic review and meta-analysis (PROSPERO: CRD42020156169) aimed to quantify overall and domain-specific self-reported anhedonia in people with schizophrenia compared to nonpsychiatric controls. We performed a literature search of PsycINFO, MEDLINE, and Embase databases for dissertations and peer-reviewed articles published in English prior to June 2021.
