Adaptation of the Chabot Emotional Differentiation Scale: Turkish version validity and reliability study

BACKGROUND: The aim of the study was to adapt the Chabot Emotional Differentiation Scale (CED) for use in Turkey and to contribute to the Turkish literature by conducting a validity and reliability study on the scale. PARTICIPANTS AND PROCEDURE: The study sample consisted of 369 volunteers between 18 and 52 years of age: 279 females (75.6%) and 90 males (24.4%), selected by the convenience sampling method. The construct validity of the scale was first tested with exploratory factor analysis and subsequently with confirmatory factor analysis. The Depression Anxiety and Stress Scale (DASS-42) and the Differentiation of Self Inventory-Short Form (DSI-SF) were used to test the convergent validity of the scale. The reliability of the scale was calculated by internal consistency and test-retest methods. RESULTS: Exploratory and confirmatory factor analysis revealed that the scale has a single factor structure. In the Turkish version of the scale, the 14th item was removed from the scale due to its low factor loading. The Cronbach’s α internal consistency coefficient of the scale was found to be .86 while the test-retest reliability coefficient was calculated as .76. CONCLUSIONS: The analysis indicates that the Turkish version of the Chabot Emotional Differentiation Scale constitutes a reliable and valid measurement tool for use with a sample in Turkey.
