Thought–shape fusion (TSF) is a cognitive distortion that has been linked to eating pathology. Two studies were conducted to further explore this phenomenon and to establish the psychometric properties of a French short version of the TSF scale.


In Study 1, students (n = 284) completed questionnaires assessing TSF and related psychopathology. In Study 2, the responses of women with eating disorders (n = 22) and women with no history of an eating disorder (n = 23) were compared.


The French short version of the TSF scale has a unifactorial structure, with convergent validity with measures of eating pathology, and good internal consistency. Depression, eating pathology, body dissatisfaction, and thought-action fusion emerged as predictors of TSF. Individuals with eating disorders have higher TSF, and more clinically relevant food-related thoughts than do women with no history of an eating disorder.


This research suggests that the shortened TSF scale can suitably measure this construct, and provides support for the notion that TSF is associated with eating pathology. © 2012 by Wiley Periodicals, Inc. (Int J Eat Disord 2013)
