Purpose:
The aims of the study were to analyze the psychometric properties of the Spanish version of the Thought-Action Fusion Questionnaire (TAF-SP), as well as to determine its validity by evaluating the relationship of the TAF-SP to different instruments.
Patients And Methods:
TWO GROUPS WERE STUDIED: one comprising 146 patients with eating disorders; and another a group of 200 students.
Results:
THREE FACTORS WERE OBTAINED: TAF-Moral; TAF-Likelihood-others; and TAF-Likelihood-oneself. The internal consistency of the TAF-SP was determined by means of Cronbach's α coefficient, with values ranging between 0.84-0.95. The correlations with other instruments refected adequate validity. The three-factor structure was tested by means of a linear structural equation model, and the structure fit satisfactorily. Differences in TAF-SP scores between the diagnostic subgroups were also analyzed.
Conclusion:
The TAF-SP meets the psychometric requirements for measuring thought-action fusion and shows adequate internal consistency and validity.
