The Investigation Factor Structure and Psychometric Properties of Short Version of Trait Thought–Shape Fusion Scale in College Students

The aim of current research has been the Investigation Factor Structure and Psychometric Properties of Short Version of  Thought–Shape Fusion (TSF) Scale in College Students. In this correlation study, 204 female students of the Shahid Chamran University of Ahvaz were selected by cluster sampling method and completed the Short Version of Thought–Shape Fusion Scale(TSF) (Coelho et al, 2013), Body Shape Questionnaire C8 (BSQ-8C) (Welch et al, 2012) and Body Image Concern Inventory (BICI)  (Littleton et al, 2005). Exploratory and confirmatory factor analysis and Pearson correlation coefficient were used to determine the validity. To determine the reliability, three methods of Cronbach's alpha, Guttman coefficient, and Spearman-Brown spilling were used. The results showed that this scale has a four-factor structure that explains 62.77% of the variance. Confirmatory validity was confirmed (RMSEA=0.07). Convergent validity with Body Shape Questionnaire C8 0.68 and body image concern Inventory 0.40 and also reliability by method and also reliability by Cronbach Alpha=0/91, Spearman-Brown splitting Alpha=0/94 and Guttmanspiliting Alpha = 0/94 were calculated The findings of the present study show that the Persian version of the short form of thought-shape fusion for study in the student population has acceptable psychometric properties and can be used as a valid tool for psychological research and clinical studies.
