The Reliability and Validity Study of the Eating-related Intrusive Thoughts Inventory (INPIAS)

Summary/Abstract: Intrusive thoughts (ITs) have been addressed with a transdiagnostic conceptualization recently. The Eating-related Intrusive Thoughts Inventory (INPIAS), composed of eating-related ITs (Part 1), consequences of interference (Part 2A) and control strategies (Part 2B) of ITs, was developed to examine ITs in Eating Disorders (EDs). The Turkish adaptation of INPIAS via reliability and validity analyses was conducted in this study. The sample consisted of 339 university students. INPIAS and Eating Disorder Examination Scale and Body Image Scale (for concurrent validity), Obsessive-Compulsive Inventory-Revised Form, Beck Anxiety Scale and Beck Depression Scale (for convergent validity) and the Demographics Form were used. Results revealed that the five-factor solution from the exploratory factor analysis (Part 1) and the original factor structures (Part 2A and Part 2B) showed a better fit. INPIAS had positive correlations with other scales. The reliability scores revealed Cronbach alpha values of .98 (Part 1), .92 (Part 2A), and .89 (Part 2B) and test-retest correlations of .98 (Part 1), .93 (Part 2A), and .92 (Part 2B). So, INPIAS may be utilized to examine ITs related to eating, diet, body image, exercise, and related control strategies. INPIAS is assumed to enlighten future studies about the relationship between ITs and EDs.
