Turkish adaptation of the Short Schema Mode Inventory.

Abstract

The purpose of the current study is to present the psychometric properties of the Short Schema Mode Inventory in the Turkish culture. The study sample comprised 1,287 participants, including both clinical and nonclinical participants. The age of the participants ranged between 18 and 48 years. The construct validity of the scale was tested using confirmatory factor analysis. The internal (Cronbach's alpha) and test-retest reliability coefficients were used to examine the reliability of the scale. Discriminant validity was investigated by comparing the nonclinical and clinical participants. Concurrent validity was tested via the Splitting Scale. The results of the study showed that the tested model had good data-model fit statistics. Additionally, the reliability analyses revealed that the scales had good internal and test-retest reliability coefficients. A significant association was found between the subscales of the Schema Mode Inventory. Furthermore, the scores of the clinical participants were significantly higher compared with the scores of the nonclinical participants for the maladaptive schema modes. Nonetheless, the participants in the nonclinical group had significantly higher levels of the healthy schema modes than individuals in the clinical group. The results of this study demonstrated that the Schema Mode Inventory was a reliable and valid instrument to measure schema modes in the Turkish population.
