Abstract:
Objective: To explore the feature and influencing factors of anhedonia in schizophrenia. Methods: A total of 71 schizophrenia patients and 50 healthy controls were recruited during December 2018 and December 2019. Positive and Negative Syndrome Scale (PANSS) was used for assessing psychotic symptoms. Temporal Experience of Pleasure Scale (TEPS) and Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) were applied to the evaluation of anhedonia and cognitive function respectively for each subject. Results: The evaluation result of TEPS showed both anticipatory and consummatory pleasure scores were lowered in patients with schizophrenia than those in healthy people (P=0.000). Stepwise linear regression analysis showed that negative subscale score of PANSS (B=-0.895, P=0.002) and delayed memory score of RBANS (B=0.265, P=0.001) were associated with anhedonia in schizophrenia. Conclusion: Patients with schizophrenia exhibit anticipatory and consummatory anhedonia, both of which are influenced by negative symptoms and delayed memory in schizophrenia.
