Background: Success of perceived self-management has been highlighted and researched in relation to patient with diabetes, as it may have a positive impact on their treatment adherence. The purpose of this study was to investigated the psychometric properties of Perceived Diabetes Self- Management Scale (PDSMS) in Turkish people with type 2 diabetes. Methods: This study design is methodological. The study recruited 263 patients. Language validity of PDSMS was tested. The psychometric properties of the Turkish PDSMS (T-PDSMS) were examined through internal consistency, stability, construct validity, confirmatory factor analysis, concurrent validity, and predictive validity. Results: Internal consistency of the total scale was 0.77 (coefficient α). Findings identified that exploratory factor analysis revealed with 47.96% of total variance explained. The factor loading ranged from 0.39 to 0.65 for 7 items. The confirmatory factor analysis had good fitness indices; the norm χ2 was 19.11, χ 2/df value was lower than 2, GFI was 0.95, CFI was 0.99, SRMR was 0.02, and RMSEA was 0.037. The instrument showed good reliability and concurrent validity with Health Belief Model Scale and Diabetes Self-Efficacy Scale (p:0.000). Assessment of predictivity of the scale, PDSMS scores correlated with diabetes outcomes such as BMI, FBG, PPG, and HbA1c (p< 0.001). Conclusions: The T-PDSMS which is consist of 7 items and one dimension is a valid and reliable measurement tool that is ready for clinical use by health professions. [ABSTRACT FROM AUTHOR] |
