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 LETPMS 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.
