Imagery re-scripting for PTSD: session content and its relation to symptom improvement.

Area of Science:

• Psychotherapy research
• Clinical psychology
• Trauma treatment

Background:

• Imagery rescripting (ImRs) is a novel therapeutic technique for intrusive imagery.
• Unlike traditional methods, ImRs focuses on transforming imagery rather than exposure or cognitive challenging.
• A detailed understanding of ImRs mechanisms is needed for treatment optimization.

Purpose of the Study:

• To develop a coding scheme for ImRs psychotherapy elements.
• To identify potential ImRs mechanisms linked to therapeutic change.
• To assess these mechanisms in individuals with post-traumatic stress disorder (PTSD).

Main Methods:

• Literature review to identify potential ImRs mechanisms.
• Development of a coding scheme for these mechanisms.
• Assessment of codes in relation to short-term outcomes in 27 PTSD patients undergoing ImRs.

Main Results:

• Several ImRs elements were identified as potentially important for symptom change.
• These include timing of image change, degree of new image activation, and associated processes.
• Rescript believability, narrative coherence, and cognitive/emotional shifts were also significant.

Conclusions:

• The developed coding scheme aids in understanding ImRs mechanisms.
• Specific factors like image transformation, believability, and emotional shifts are linked to symptom reduction in PTSD.
• This research provides a foundation for optimizing ImRs therapy.
