About this study
Official title: Co-occurring Eating Disorders and Posttraumatic Stress Disorder: Facilitating Full and Sustained Recovery Through Empirically-Based Concurrent Treatment
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.
Read the detailed description
Standard ED treatment is characterized by partial response in many individuals, and the risk of relapse is high. This, in combination with significant rates of comorbid PTSD, evidence that trauma history can negatively impact ED treatment outcome, and the observation that PTSD may be a central ED maintaining factor in these individuals, has led us to develop a program of research aimed at demonstrating that the alleviation of PTSD symptoms concurrent with ED treatment facilitates a fuller and sustained ED recovery for these individuals.
The specific aims of this initial randomized controlled trial (RCT) are to determine: (1) the immediate and short-term efficacy of concurrent evidence-based ED and PTSD treatment in reducing PTSD symptoms relative to standard ED treatment; and (2) estimates of the effect sizes of concurrent treatment on ED symptomatology relative to standard ED treatment at post-treatment and follow-up.
Primary Hypothesis:
- Concurrent CBT for ED and PTSD will result in significantly greater improvements in clinician-rated PTSD symptoms at post-treatment, as well as at 3- and 6-month follow-up compared with CBT for ED alone. Secondary Hypotheses:
- Concurrent CBT for ED and PTSD will result in significantly greater improvements in self-reported PTSD symptoms at post-treatment, as well as at 3- and 6-month follow-up compared with CBT for ED alone.
- Concurrent CBT for ED and PTSD will result in significantly greater improvements in concomitant symptoms (e.g., anxiety and depression) at post-treatment, as well as at 3- and 6-month follow-up compared with CBT for ED alone.
Exploratory Research Questions
- What proportion of participants experience reliable improvement in ED symptomatology and what proportion experience reliable deterioration in ED symptomatology over the course of each treatment?
- What is the relative efficacy of concurrent CBT for ED and PTSD versus CBT for ED alone in reducing functional deficits at post-treatment, and 3- and 6-month follow-up?
- What is the relative efficacy of concurrent CBT for ED and PTSD versus CBT for ED alone in improving other concomitant symptoms at post-treatment, and 3- and 6-month follow-up?
METHOD:
Following a course of intensive ED treatment in the inpatient or day hospital ED program at University Health Network (UHN), participants will be randomly assigned to receive either individually-administered: (1) standard CBT for ED alone or (2) concurrent CBT for ED and PTSD. Participants in both conditions will receive 16 sessions. Eleven of the 16 concurrent CBT for ED and PTSD sessions will be 90 minutes long in order to accommodate the administration of CBT for ED and PTSD. Participants in the CBT for ED alone condition will also receive eleven 90-minute sessions in order to control for time in therapy. In the CBT for ED condition, therapists will have more time to cover the ED-related content. Accordingly, both treatments will consist of eleven 90-minute sessions and five 50-minute sessions, with two sessions per week for the first 8 sessions, weekly sessions for the following 6 sessions, and biweekly for the final two sessions.
Participants will be assessed pre-CBT for ED/PTSD and post-CBT for ED/PTSD, as well as 3 and 6 months after treatment. The assessors will be blind to treatment condition, and an intent-to-treat (ITT) approach to data collection and analysis will be adopted. ED and PTSD symptoms will also be assessed on a weekly basis during the study treatments.
STATISTICS:
- Primary hypothesis: Changes in clinician-rated PTSD symptoms will be analyzed using multilevel modeling, including a random effect for time and fixed effects for therapy condition, time, and the condition by time interaction. Change in PTSD symptoms over time and differences between the conditions over time will be examined. Empirically derived covariates that significantly reduce error variance will be used. Cohen's d effect sizes will be calculated.
- Secondary hypotheses: Changes in self-reported PTSD symptoms, anxiety, and depresion will be analyzed using multilevel modeling, including a random effect for time and fixed effects for therapy condition, time, and the condition by time interaction. Change in PTSD symptoms, anxiety, and depression over time and differences between the conditions over time will be examined. Empirically derived covariates that significantly reduce error variance will be used. Cohen's d effect sizes will be calculated.
- The proportion of participants who experience reliable improvement and the proportion who experience reliable deterioration in ED symptomatology in each therapy condition will be calculated using reliable change criteria (Jacobson \& Truax, 1991).
- The proportion of participants meeting diagnostic criteria for PTSD and an eating disorder will be compared between conditions at post-treatment and follow-up.
- Changes in other concomitant symptoms and functional deficits will be analyzed using multilevel modeling as described above.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CBT for EDBehavioural
Also called CBT for ED only
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.
Concurrent CBT for ED and PTSDBehavioural
Also called 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.
| Study group | Role | What they receive |
|---|---|---|
| CBT for ED only | Active comparator | In this arm, participants will receive CBT for ED following intensive ED treatment (see intervention section for description). Receives: Behavioral: CBT for ED |
| Concurrent CBT for ED and PTSD | Experimental | In this arm, participants will receive concurrent CBT for ED and PTSD following intensive treatment. (see intervention section for description). Receives: Behavioral: Concurrent CBT for ED and PTSD |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in clinician-assessed PTSD symptoms
Change in PTSD symptoms will be assessed using the Clinician-Administered PTSD Scale (CAPS; Weathers et al., 2013). Scores range from 0-80 with a higher score representing higher severity.
Measured: pre-treatment, end of treatment (after approximately 14 weeks), 3- and 6-month follow up
Secondary outcomes (3)
Change in self-reported PTSD symptoms
The PTSD Checklist (PCL; Weathers, Litz, Keane, Palemeri, Marx, \& Schnurr, 2013) will provide a measure of change in self-reported PTSD symptoms. Scores can range from 0-80 with a higher score indicating higher severity.
Measured: pre-treatment, end of treatment (after approximately 14 weeks), 3- and 6-month follow up
Change in anxiety
Change in anxiety will be assessed with the anxiety scale of the Depression Anxiety Stress Scales (DASS; Lovibond \& Lovibond, 1995). Scores can range from 0-42 with a higher score reflecting higher anxiety.
Measured: pre-treatment, end of treatment (after approximately 14 weeks), 3- and 6-month follow up
Change in depression
Change in depression will be assessed with the depression scale of the Depression Anxiety Stress Scales (DASS; Lovibond \& Lovibond, 1995). Scores can range from 0-42 with a higher score reflecting higher depression.
Measured: pre-treatment, end of treatment (after approximately 14 weeks), 3- and 6-month follow up
