Gender Differences in the Clinical Characteristics of Psychotic Depression: Results from the CRESCEND Study

摘要

Objective To test whether there are gender differences in the clinical characteristics of patients with psychotic depression (PD). Methods Using data from the Clinical Research Center for Depression (CRESCEND) study in South Korea, we tested for potential gender differences in clinical characteristics among 53 patients with PD. The Psychotic Depression Assessment Scale (PDAS) and other psychometric scales were used to evaluate various clinical features of the study subjects. Independent t -tests were performed for normally distributed variables, Mann-Whitney U-tests for non-normally distributed variables, and χ2 tests for discrete variables. In addition, to exclude the effects of confounding variables, we carried out an analysis of covariance (ANCOVA) for the normally distributed variables and binary logistic regression analyses for discrete variables, after adjusting the effects of marital status. Results We identified more prevalent suicidal ideation (adjusted odds ratio [aOR]=10.316, p =0.036) and hallucinatory behavior (aOR=8.332, p =0.016), as well as more severe anxiety symptoms (degrees of freedom [df]=1, F =6.123, p =0.017), and poorer social and occupational functioning (df=1, F =6.265, p =0.016) in the male patients compared to the female patients. Conclusion Our findings suggest that in South Korean patients with PD, suicidal ideation, hallucinatory behavior, and anxiety is more pronounced among males than females. This should be taken into consideration in clinical practice.
