[Can Thought-Action Fusion Be Induced and Alleviated?]

Area of Science:

• Cognitive Psychology
• Clinical Psychology
• Psychopathology

Background:

• Thought-action fusion (TAF) is a cognitive bias implicated in obsessive-compulsive disorder (OCD).
• Understanding TAF's appraisal process and potential interventions is crucial for OCD treatment.
• Existing methods for inducing and assessing TAF have limitations.

Purpose of the Study:

• To examine the effects of TAF induction on appraisal processes using an enhanced paradigm.
• To evaluate the efficacy of psychoeducation (PE) in alleviating TAF induction experiences.
• To compare TAF induction and PE effects across individuals with high OCD traits, low OCD traits, and diagnosed OCD patients.

Main Methods:

• An enhanced paradigm integrating Sentence Completion Task (SCT) and perseverative reasoning (PR) was used to induce TAF.
• Participants included high OCD trait (n=47), low OCD trait (n=70), and OCD patients (n=52).
• Appraisal components (TAF-Likelihood, TAF-Morality) were assessed pre- and post-induction and post-PE (TAF-focused or stress-focused information).

Main Results:

• The enhanced paradigm successfully induced the likelihood component of TAF.
• Psychoeducation on TAF was effective in reducing TAF-Likelihood but not TAF-Morality.
• No significant differences in TAF-Likelihood were found between OCD patients and analogue groups.
• Unexpectedly, high OCD trait participants scored higher on TAF-Morality than OCD patients.

Conclusions:

• The developed paradigm effectively induces TAF likelihood.
• Psychoeducation shows potential for reducing TAF likelihood, a key cognitive bias in OCD.
• Findings suggest TAF-Likelihood and TAF-Morality may be differentially affected by interventions and trait levels.
