Thought Action Fusion Scale-Revised – TAFS-R
A 19-item self-report scale measuring the cognitive bias of thought-action fusion, which is the belief that thoughts are equivalent to actions or can influence real-world outcomes.
Scale Development & Technical Details
Scale Overview
The Thought Action Fusion Scale-Revised – TAFS-R was developed by Shafran, R., Thordarson, D. S., & Rachman, S. (1996). It is designed to measure Thought-Action Fusion. The scale is intended for use with Adults.
Scale Structure
This instrument consists of 19 items organized into 3 factors/subscales: TAF-Moral, TAF-Likelihood Other, TAF-Likelihood Self.
| Factor / Subscale | Items | N |
|---|---|---|
| TAF-Moral | 1,3,4,6,8,10,11,13,15,17,18,19 | 12 |
| TAF-Likelihood Other | 2,5,7,9 | 4 |
| TAF-Likelihood Self | 12,14,16 | 3 |
Response Format
Respondents rate each item using a custom response format.
Response anchors: 0 = Disagree Strongly, 1 = Disagree, 2 = Neutral, 3 = Agree, 4 = Agree Strongly.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Total scores range from 0 to 76. Interpretation guidelines:
- Low Thought-Action Fusion: 0 – 19
- Moderate Thought-Action Fusion: 20 – 38
- High Thought-Action Fusion: 39 – 57
- Very High Thought-Action Fusion: 58 – 76
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Cronbach's alphas from 0.85 to 0.96.
Administration
The scale is self-administered and typically takes approximately 5 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
