Abstract

Background: This study, examines the applicability of the Lifestyle Evaluation Tool for Patients with Metabolic Syndrome (LET-PMS) questionnaire, originally developed for general population, on psychiatric patients with metabolic syndrome.
Methods: The study included 320 patients diagnosed with schizophrenia spectrum disorder (N=190), bipolar spectrum disorder (N=65), and depressive disorder (N=65). They were provided assignments using 36 items from the LET-PMS questionnaire and various established scales. The evaluation encompassed psychometric properties of reliability, exploratory factor, and confirmatory factor analysis.
Results: We refined the LET-PMS questionnaire by eliminating six items through a reliability test. The resultant questionnaire exhibited six factors. The overall Cronbach’s alpha value was 0.896, with factor-specific reliability coefficients ranging from 0.730 to 0.859. Based on confirmatory factor analysis of the adapted LET-PMS, the root mean square error of approximation was 0.069 (0.05-1.1). Goodness-of-fit and comparative fit indexes were 0.815 and 0.821, respectively. All 30 items met the criteria for suitable configuration.
Conclusion: The LET-PMS questionnaire demonstrated robust internal consistency and sound structural validity, making it suitable for psychiatric patients with metabolic syndrome.
