Summary

Although psychotherapy for eating disorders (EDs) can be effective, approximately 50% of those who complete a course of the best available therapy continue to have significant ED symptoms at the end of treatment. Posttraumatic stress disorder (PTSD) commonly co-occurs with EDs and is thought to be one reason why some individuals do not remit from their ED with best available treatment or relapse following treatment. In particular, ED behaviours can function as coping methods for PTSD symptoms, and thus interfere with successful and lasting ED recovery. The main objective of this initial treatment trial is to determine whether a concurrent treatment approach, in which PTSD symptoms are treated at the same time as ED symptoms, provides an advantage over standard ED treatment by successfully alleviating PTSD symptoms.

Forty participants who have both an ED and PTSD will be assigned to receive either (1) standard ED psychotherapy alone or (2) standard ED psychotherapy concurrent with PTSD psychotherapy. After treatment, participants will be followed for a period of 6 months to determine whether improvements made during therapy are maintained after treatment. ED and PTSD symptoms, as well as concomitant symptoms (e.g., anxiety and depression) will be assessed immediately before and after treatment, as well as 3 and 6 months after treatment.

Conditions

Interventions

BEHAVIORAL

CBT for ED

Cognitive behavior therapy (CBT) for eating disorders (ED) is a 16-session individual therapy protocol which will focus on maintaining improvements in eating following intensive treatment, as well as addressing overconcern with weight/shape. Interventions will be adopted from the Enhanced CBT for ED manual.

BEHAVIORAL

Concurrent CBT for ED and PTSD

The concurrent ED and PTSD intervention will consist of 16 sessions of CBT for both PTSD and for ED (ED interventions described above). CBT for PTSD will be based on interventions in the Cognitive Processing Therapy (CPT) manual.
