Eating disorders (EDs) and posttraumatic stress disorder (PTSD) frequently co-occur and can share a functional relationship. The primary aim of this initial randomized controlled trial was to determine whether integrated cognitive-behavioral therapy (CBT) for co-occurring ED-PTSD was superior to standard CBT for ED in improving PTSD symptoms. Intervention safety and desirability, as well as the relative efficacy of the treatments in improving anxiety, depression, and ED symptomatology, were also examined.

Following a course of intensive ED treatment, individuals with ED-PTSD were recruited to participate and randomized to integrated CBT for ED-PTSD or standard CBT for ED. The sample consisted of 42 individuals with a range of ED diagnoses. Outcomes were assessed at end-of-treatment, 3-, and 6-month follow-up using interview and self-report measures.

Mixed models revealed significant interactions of time and therapy condition on clinician-rated and self-reported PTSD symptom severity favoring Integrated CBT for ED-PTSD. Both treatments were associated with statistically significant improvements in PTSD, anxiety, and depression. Improvements were maintained at 3- and 6-month follow-up. There was good safety with both interventions, and satisfaction with both treatments was high. However, there was a stronger preference for integrated treatment.

Integrating CBTs for PTSD and ED following intensive ED treatment is safe, desirable, and efficacious for improving PTSD symptoms. Future studies with larger sample sizes are needed to determine whether Integrated CBT for ED-PTSD provides benefits over standard CBT for ED with respect to ED outcomes.

This study was conducted to investigate and clinically assess comorbid depression and its relevance in individuals suffering from gambling disorders. The DSM-V defines the condition of gambling disorder as a persistent and recurrent problematic gambling behaviour leading to clinically significant impairment or distress.

A total of 61 subjects with gambling disorders were assessed using the Structured Clinical Interview for the DSM-IV (SCID-I), the South Oaks Gambling Screen (SOGS) and the Major Depression inventory (MDI).

Two-way analysis of variance showed highly significant treatment outcomes associated with reductions in SOGS, F(1,60)=84.79, p<0.0001, MDI, F(1,60)=38.13, p<0.0001, craving, F(1,60)=29.59, p<0.0001, and gambling control, 47.65, p<0.0001. There was also a highly significant outcome associated with comorbidity in MDI, F(1,60)=9.17, p<0.0001. Finally, there was a significant interaction effect between treatment outcome and comorbidity, F(1,60)=3.90, p<0.005, suggesting that both treatment and comorbidity contributed to reductions in depressive symptoms.

These results suggest and highlights the importance and benefits of integrated treatment of gambling disorders and its comorbidity, but also stresses the importance of adequate screening and detection of these two variables.
