Psychological Adaptive Mechanism Maturity Predicts Good Outcomes in Treatment for Refractory PTSD.

Area of Science:

• Psychiatry
• Psychology

Background:

• Post-traumatic Stress Disorder (PTSD) severity varies, with severe cases often requiring intensive residential rehabilitation.
• The effectiveness of these treatments can be enhanced by understanding patient psychological mechanisms.

Purpose of the Study:

• To investigate the association between psychological adaptive mechanisms (PAMs), also known as ego defense mechanisms, and treatment outcomes in combat-related PTSD patients undergoing residential rehabilitation.

Main Methods:

• An association study involving 115 adult male combat-related PTSD patients in residential rehabilitation.
• Defense Style Questionnaire (DSQ) administered on admission; PTSD Checklist-Military Version (PCL-M) and Mississippi Scale for Combat-Related PTSD (M-PTSD) administered on admission and discharge.
• Pearson's correlation used to test associations between DSQ scores and PTSD change scores (p < 0.05).

Main Results:

• Averaged mature PAM scores on the DSQ were significantly associated with improved PCL-M (p = 0.03) and M-PTSD (p = 0.04) change scores.
• Averaged neurotic or immature PAM scores showed no significant association with PTSD scale change scores.

Conclusions:

• Patients with predominantly mature PAMs are likely to benefit from residential PTSD rehabilitation.
• Individuals with neurotic or immature PAMs may not experience significant positive change with this treatment modality.
• Alternative treatments may be more suitable for PTSD patients with neurotic or immature adjustment mechanisms.
