Psychometric Properties of the Spanish Version of the Thougth-Shape Fusion Questionnaire

Abstract

The objectives of the study were to analyze the psychometric properties, factor structure and internal consistency of the Spanish version of the Thought-Shape Fusion Questionnaire (TSF-Q), as well as to determine its validity by evaluating the relationship of the TSF-Q to different instruments.Two groups were studied: one comprising 146 patients with a diagnosis of anorexia (n = 82), bulimia (n = 33) or unspecified eating disorder (n = 31), and another group of 115 undergraduates with no history of psychological disorder. All participants completed the TSF-Q, TAF-Q, EDI-2, STAI, BDI and SCL-90-R. Differences in TSF-Q scores between the diagnostic subgroups were also analyzed.Two factors were obtained which coincided with the two sections indicated by the authors of the questionnaire: conceptual and interpretative. The internal consistency of the TSF-Q and its subscales was determined by means of Cronbach's alpha, with values ranging between .93 and .96. The correlations with other instruments reflected adequate validity. There were no significant differences between the diagnostic subgroups.The Spanish version of the TSF-Q meets the psychometric requirements for measuring thought-shape fusion and shows adequate internal consistency and validity.

Over‐evaluation of thoughts about food: Differences across eating‐disorder subtypes and a preliminary examination of treatment effects

“…However, the experience of TSF has not yet been studied systematically across the eating‐disorder subtypes. An initial comparison across eating disorder subtypes using a Spanish translation of the TSF scale suggests that there are no differences across the groups . However, these researchers did not differentiate between individuals with the restrictive versus binge/purge subtype of AN, and this may have obscured potential differences across the groups.…”

“…An initial comparison across eating disorder subtypes using a Spanish translation of the TSF scale suggests that there are no differences across the groups. 7 However, these researchers did not differentiate between individuals with the restrictive versus binge/purge subtype of AN, and this may have obscured potential differences across the groups. Recent evidence shows that individuals with the restrictive subtype of AN report significantly more delusional body image beliefs than do individuals with the binge/purge subtype of AN, or those with BN.…”

Adaptation of Food Craving Inventory to Turkish culture: a validity and reliability study

“…After the validation of the original inventory, other researchers were able to adapt the inventory as regards both structure and category. Food Craving Inventory has been adapted for many cultures including United Kingdom, Germany, Spain, Brazil, Japan and Iranian [21][22][23][24][25]. The versions of United Kingdom and Germany feature the same four-factor structure [21,23].…”

“…The versions of United Kingdom and Germany feature the same four-factor structure [21,23]. The Spain and Brazil versions of inventory have a threefactor structure [22,31]. Japan and Iranian versions of the inventory have a five-factor structure [24,25].…”

Relevance of the Thought–Shape Fusion Trait Questionnaire for healthy women and women presenting symptoms of eating disorders and mixed mental disorders

“…The phenomenon of thought-shape fusion (TSF) has been described as a specific cognitive distortion in eating disorders (EDs; Shafran, Teachman, Kerry, & Rachman, 1999) based on the findings of thought-action fusion (TAF; Shafran & Rachman, 2004;Shafran, Thordarson, & Rachman, 1996) in individuals with obsessivecompulsive disorder (OCD). It has been shown that TAF and TSF are highly correlated in clinical samples of patients suffering from an ED as well as in healthy controls (HCs; Coelho, Carter, McFarlane, & Polivy, 2008;Coelho, Ouellet-Courtois, Purdon, & Steiger, 2015; Jauregui Lobera, Santed, Shafran, Santiago, & Estébanez, 2013).…”
