Abstract :

Aim: We aimed to develop the Metabolic Syndrome Knowledge Level Scale (MetS–KS) for Turkey, and to determine the validity and reliability of this scale.

Material–Methods: This study has been carried out in two stages. The first stage: MetS–KS was developed and its validity and reliability were studied. The second stage: The construct validity of MetS–KS was retested by Confirmatory Factor Analysis (CFA) on another study group.

Results: Of 477 individuals who constituted the study group, 250 (52.4%) were males. The item difficulty indices of the items of MetS–KS were between 0.40 and 0.74. Correlation coefficients of the corrected items ranged from 0.46 to 0.82. In our study, 27% of the upper group have higher median score (22.0 (min: 20.0, max: 25.0) than 27% of the lower group (1.0 (min: 0.0, max: 15.0), (z=15.558; p<0.001). For MetS–KS, the Cronbach‘s alpha coefficient was 0.95. When any of the items were removed, the Cronbach alpha coefficient was not significantly increased (p>0.05). Confirmatory Factor Analysis (CFA) was performed to test the construct validity of MetS–KS in Exploratory Factor Analysis (EPA). In CFA, the following results were obtained: χ2 / df value was 2.26. Root Mean Square Error of Approximation (RMSEA) was 0.06. Standardized Root Mean Square Error (SRMR) was 0.04. Comparative Fit Index (CFI) was 0.92. Goodness of fit Index (GFI) was 0.86, and Adjusted Goodness of fit Index (AGFI) was 0.83.

Conclusion: MetSKLS is a valid and reliable measurement tool for assessing MetS knowledge level for Turkish population.
