Thought-shape fusion (TSF) is a cognitive distortion associated with eating pathology. TSF is a phenomenon associated with perceptions of weight gain, body dissatisfaction and moral wrongdoing after merely thinking about consumption of high-caloric foods. Women who are overweight are less susceptible to inductions of TSF than are women who are normal-weight.
Obese adolescents were less susceptible to a TSF induction than were lean adolescents (i.e., they reported lower state TSF in comparison with lean adolescents, and did not demonstrate an increase in state TSF relative to a neutral induction). Eating pathology, but not obesity status or gender, predicted trait TSF.
Previous research has demonstrated that imagining consumption of high-caloric foods can lead to feelings of guilt, and perception of weight gain and moral wrongdoing. This psychological response is known as thought-shape fusion (TSF).
This study was conducted to assess the susceptibility of obese and lean adolescents to TSF.
To investigate TSF susceptibility in adolescents, and predictors of this distortion, a total of 82 adolescents (44 obese and 38 lean) were randomly assigned to receive either a TSF or a neutral induction. Subsequent TSF reactivity was assessed (i.e., levels of state TSF after the induction), as was trait TSF, eating pathology and depression.
The results suggest that obese adolescents are less susceptible to TSF than are lean adolescents, as lean (but not obese) adolescents reported significantly higher state TSF relative to participants who received the neutral induction. Similarly, lean adolescents who were exposed to a TSF induction reported higher state TSF than did obese adolescents. Furthermore, obesity did not emerge as a predictor of trait TSF. Factors that may account for decreased TSF susceptibility in obese adolescents relative to lean adolescents will be discussed.
思维-体型融合（TSF）是一种与饮食病理学相关的认知扭曲。TSF是一种现象，即仅仅在想到食用高热量食物后，就会出现体重增加的认知、身体不满以及道德过错感。超重女性比体重正常的女性更不易受到TSF诱导。
肥胖青少年比瘦青少年更不易受到TSF诱导（即，与瘦青少年相比，他们报告的状态TSF较低，并且相对于中性诱导，他们的状态TSF没有增加）。饮食病理学而非肥胖状况或性别可预测特质TSF。
先前的研究表明，想象食用高热量食物会导致内疚感、体重增加的认知以及道德过错感。这种心理反应被称为思维-体型融合（TSF）。
本研究旨在评估肥胖和瘦青少年对TSF的易感性。
为了调查青少年对TSF的易感性以及这种扭曲的预测因素，总共82名青少年（44名肥胖青少年和38名瘦青少年）被随机分配接受TSF诱导或中性诱导。随后评估TSF反应性（即诱导后的状态TSF水平），以及特质TSF、饮食病理学和抑郁情况。
结果表明，肥胖青少年比瘦青少年更不易受到TSF诱导，因为与接受中性诱导的参与者相比，瘦青少年（而非肥胖青少年）报告的状态TSF显著更高。同样，接受TSF诱导的瘦青少年报告的状态TSF高于肥胖青少年。此外，肥胖并未成为特质TSF的预测因素。本文将讨论相对于瘦青少年，肥胖青少年TSF易感性降低的可能原因。
