Confirmatory Factor Analysis of the Sexual Desire Inventory in Patients with Schizophrenia
摘要
Objective: The aim of this study was to use confirmatory factor analysis (CFA) in a sexual desire inventory of schizophrenia patients to investigate the relationship between sexual desire in schizophrenic patients and related socio-demographic factors. Methods: Eighty-nine patients with remitted schizophrenia were consecutively selected from a teaching hospital in southern Taiwan. All patients completed the sexual desire inventory (SDI) and demographic and clinical data were obtained. Results: The results of the CFA show the three-factor model (dyadic, solitary and mixed) from the SDI was the best fit (P＝0.68; goodness-of-fit index＝0.93). Statistically significant differences were demonstrated for gender and duration of illness comparing to the three factors. Multiple linear regression showed an inverse relationship between duration of illness and sexual desire. Conclusion: The study can be used as a reminder of sexual desire issue in clinical practice.
