Imaging Outcomes of Cognitive Behavioral Therapy (CBT) for Battered Women With Posttraumatic Stress Disorder

University of California, San Diego41 enrolled

Overview

Identifying neural mechanisms of posttraumatic stress disorder (PTSD) treatment could help elucidate reasons for variable treatment response and identify novel treatment targets. Exposure-based therapies have been associated with decreased amygdala and increased cingulate cortex response during emotional processing. The current study examined whether cognitive therapy for PTSD in women reduces activation in insula and amygdala and enhances activation in prefrontal regions during emotional anticipation and pre-treatment prefrontal activation predicts treatment response.

Outcomes

Primary Outcomes

Clinician-Administered PTSD Scale (CAPS)

The CAPS is a widely used measure of PTSD severity. Intent was to administer 10 sessions of CBT over a period of 10-14 weeks. Primary outcome was CAPS at the end of CBT administration.

Time frame: After 10 sessions of cognitive behavioral therapy (CBT) (10-14 weeks)

Secondary Outcomes

CAPS 3 months post-treatment

Time frame: 3 months post-treatment
