Randomized Clinical Trial of Imagery Stabilization and Rescripting Therapy for Psychiatric Outpatients with...

Area of Science:

• Psychiatry and Mental Health
• Clinical Psychology
• Trauma Studies

Background:

• Posttraumatic stress disorder (PTSD) significantly impacts adult mental health.
• Novel psychotherapeutic interventions are needed to address PTSD effectively.
• Imagery-based therapies offer a potential alternative for PTSD treatment.

Purpose of the Study:

• To evaluate the safety and efficacy of Imagery Stabilization and Rescripting Therapy (ISRT) for adults with PTSD.
• To compare ISRT with non-trauma-focused cognitive behavioral therapy (CBT) in a randomized clinical trial.
• To assess treatment outcomes at posttreatment and 6-month follow-up.

Main Methods:

• A randomized clinical trial involving 86 adults diagnosed with PTSD.
• Intervention group received 8 sessions of ISRT (n=59).
• Control group received 8 sessions of CBT (n=27).
• Standardized clinical assessments (CAPS-5, HDRS, HARS) and self-report questionnaires were used.
• Data collected at pretreatment, posttreatment, and 6-month follow-up.

Main Results:

• Dropout rates were comparable between ISRT (28.8%) and CBT (25.9%) groups.
• Both completer and intention-to-treat analyses indicated that ISRT favored improvements in clinical status, PTSD symptoms, and quality of life.
• These positive effects were observed posttreatment and at the 6-month follow-up.

Conclusions:

• Imagery Stabilization and Rescripting Therapy (ISRT) demonstrates safety and effectiveness in treating PTSD.
• ISRT presents a viable therapeutic option for individuals suffering from posttraumatic stress disorder.
• Further research may explore ISRT's long-term impact and applicability across diverse PTSD populations.
