The Turkish adaptation, validity, and reliability of the Fragmented Self Inventory

Summary/Abstract: The Fragmented Self Inventory (FSI) is a self-report measurement tool developed to examine the experiences of fragmented self as defined by Heinz Kohut. The scale focuses on the experiences in two axes of the self in the context of psychoanalytic self-psychology, namely fragmented grandiosity (FSI-FG) and fragmented idealization (FSI-FI). This study aimed to adapt the FSI into Turkish and to evaluate its psychometric properties in a Turkish-speaking sample. Data were collected from 495 participants (female = 67.88%, Mage = 33.86, SD = 12.87). Confirmatory factor analysis was conducted to test the two-factor structure of the FSI. The convergent validity of the scale was evaluated by examining the relationships of the FSI-FG and FSI-FI scores with self-esteem, pathological narcissism, self-control, discipline, emotion dysregulation, meaning in life and purpose, depression, anxiety, and stress variables. The reliability of the scale was examined by internal consistency coefficients and test-retest intraclass correlations. The results of confirmatory factor analysis supported the two-factor structure of the Turkish FSI. Higher scores on the axis of fragmented grandiosity were associated with lower self-esteem and higher symptoms of pathological narcissism, whereas higher scores on fragmented idealization were associated with poorer self-control, lower discipline, higher difficulties in emotion regulation, and higher difficulty in finding meaning and purpose in life, supporting the convergent validity of the FSI. The FSI-FG and FSI-FI subscales showed satisfactory internal consistency (McDonald’s ω = .77 and .86) and four-week test-retest reliability (ICC = .78 and .81). In the path analysis in which fragmented grandiosity and fragmented idealization predicted depression, anxiety and stress, it was found that fragmented grandiosity significantly predicted anxiety and stress, and fragmented idealization significantly predicted depression, anxiety and stress. The findings of this study indicate that the Turkish form of the FSI can be used to measure experiences of fragmented grandiosity and fragmented idealization.
