Severe eating disorders helped by CBT

In a recent study in the American Journal of Psychiatry, investigators reported that people with severe eating disorders can be effectively treated by cognitive behavioral therapy (CBT) that focuses on perfectionism, binge eating, and other related issues.

Two types of CBT were employed in the protocol (in addition to a wait-list control group). One CBT protocol focused exclusively on eating-disorder psychopathology and the other was a broader, more complex form that included treatment of mood intolerance, perfectionism, and low self-esteem.

The two CBT groups experienced significant improvement whereas the wait-list group experienced little change in symptoms. The authors noted that in addition to the direct benefit to people with eating disorders, another important implication of this finding is that hospital stays can be avoided for the majority of these patients.

Child and adolescent Anxiety: Most effective treatments combine CBT and pharmacotherapy

Authors of a new study in the New England Journal of Medicine reported that anxiety disorders in children and adolescents negatively affect school performance, family relations, and social functioning. Despite a high prevalence (10-20%), they are largely “underrecognized and undertreated.” The anxiety disorders evaluated in this study included separation and generalized anxiety and social phobia. Cognitive behavioral therapy (CBT) and selective serotonin-reuptake inhibitors (SSRIs) have already been demonstrated to be effective in this group but a randomized controlled study of the two in combination has been lacking.

To address this, children ranging in age from 7 to 17 received CBT, an SSRI (sertraline/Zoloft) or placebo, or a combination of the CBT and sertraline. The CBT involved fourteen 60-minute sessions and included anxiety-management skills and behavioral exposure to anxiety-provoking situations.

The authors found that improvement was greatest for the combination therapy (80.7%), followed by cognitive behavioral therapy alone (59.7%), then sertraline alone (54.9%), and all therapies were superior to placebo (23.7%). An interesting additional finding was that “there was less insomnia, fatigue, sedation, and restlessness associated with cognitive behavioral therapy than with sertraline.”

The authors concluded that “all three of the treatment options may be recommended, taking into consideration the family’s treatment preferences, treatment availability, cost, and time burden.”
