title: Eating-related Intrusive Thoughts Inventory: exploring the dimensionality of eating disorder symptoms.
abstract: The aims of this study were, first, to examine the structure and validity of the Eating-related Intrusive Thoughts Inventory (INPIAS), a self-report questionnaire designed to assess eating disorders related to intrusive thoughts (EDITs), and second, to explore the existence of a continuum ranging from normal to abnormal thought intrusions related to eating, weight, and shape. Participants were 574 (408 women) nonclinical community individuals. Analyses revealed that EDITs can be clustered into three sets: appearance-dieting, need to exercise, and thoughts-impulses related to eating disorders. EDITs' consequences showed a two-factor structure: emotional consequences/personal meaning and thought-action fusion responsibility; and four factors of strategies: "anxiety," suppression, obsessive-compulsive rituals, and distraction. The sample was then divided according to reported restrained eating. The High dietary restraint group reported a higher frequency of EDITs, whereas differences in the other factors were mediated by depression, anxiety, and obsessionality. The results suggest that eating disorder-related cognitions are experienced by nonclinical individuals, and distributed on a continuum.
