Manual-Driven group cognitive-behavioral therapy for adolescents with obsessive-compulsive disorder: a pilot study

OBJECTIVE

Concerns about isolation, compromised development, partial pharmacotherapy response, therapist scarcity, and inadequate cognitive-behavioral therapy (CBT) adherence led the authors to adapt a CBT protocol to a group format for adolescents with obsessive-compulsive disorder (OCD). A naturalistic, open trial of group CBT for adolescent OCD is described. The authors predicted symptom improvement and format acceptability.

METHOD

Over a 1 -year period, 18 adolescents aged 13 to 17 years with OCD received 14-week group CBT based on March and Mulle's OCD in Children and Adolescents: A Cognitive-Behavioral Treatment Manual in four consecutive sessions of five to nine patients. Eighty-three percent had undergone at least one medication trial, and 78% had previous CBT experience.

RESULTS

OCD symptoms measured by the Children's Yale-Brown Obsessive Compulsive Scale improved significantly, both statistically and clinically. Adolescents consistently shared information and designed exposure interventions for themselves and others during sessions. Repeated self-report measures confirmed adolescents' satisfaction with therapy.

CONCLUSIONS

This pilot study demonstrates that a manual-based treatment protocol may be exported for clinical use, adaptable for the end-user's needs, and palatable to adolescent patients. Clinical improvement and patient satisfaction justify further investigation in a controlled study.

Cognitive-behavioral group therapy for social phobia in female adolescents: results of a pilot study

OBJECTIVES

To examine the efficacy of cognitive-behavioral group therapy for adolescents (CBGT-A) in females with social phobia and the effect of this treatment on the risk for major depression.

METHOD

Female adolescents with social phobia (N = 35) were randomly assigned to treatment (n = 12) or no treatment (n = 23) groups. Assessments were conducted at baseline, after treatment, and at a 1-year follow-up.

RESULTS

Eleven subjects completed treatment. Sixteen weeks of treatment produced a significant improvement in interference and reduction in symptoms of social anxiety. There was a significant reduction in the number of subjects meeting DSM-IV criteria for social phobia in the CBGT-A versus the untreated group; however, at the 1-year follow-up there were no significant differences by treatment condition. There was also suggestive evidence that treatment of social phobia lowers the risk for relapse of major depression among those with a history of major depression. Combining social phobia and major depression as the outcome produced more robust treatment effects in the 1-year follow-up.

CONCLUSIONS

This pilot study provides evidence for a moderate short-term effect of CBGT-A for treating female adolescents suffering from social phobia and indicates that treatment of social phobia may result in a reduction of major depression.

Defense style and family environment

Prospective observations of the defense styles of normal individuals suggest that the quality of the childhood family environment may influence the maturity of defense styles used in adulthood. In this study, 106 female adolescent psychiatric patients completed the Defense Style Questionnaire, and the Family Environment Scale (FES). Positive family characteristics such as cohesion and expressiveness, as measured by the FES, were correlated with the report of Mature Defenses. Negative family characteristics such as conflict were correlated with the report of Immature Defenses. Similar although weaker correlations were found after controlling for the effects of depression and defensiveness on the self-report measures.

Do soft signs predict treatment outcome in obsessive-compulsive disorder?

The authors examined 21 outpatients with obsessive-compulsive disorder for five neurological soft signs and abnormalities on two neuropsychological tests before and after 10 to 12 weeks of treatment with serotonin reuptake inhibitors. Patients showed a mean of 1.8 soft signs. Prevalences were finger-to-finger, 10%; adventitious movements, 29%; mirror movements, 33%; impaired cube drawing, 33%; and agraphesthesia, 76%. The Stroop Color and Word Test was abnormal in 10% and the Controlled Oral Word Association Test was abnormal in 14% of patients. Neither the presence of specific soft signs, the number of signs present, nor a combination of signs and test abnormalities predicted a poorer response to pharmacological treatment. Some baseline soft signs and abnormalities disappeared at endpoint in medication responders and nonresponders; no clear pattern of change emerged.

Family environment of eating disordered and depressed adolescents

We designed this study to replicate previous findings which suggest a relationship between the qualities found in family environments and specific eating disorders through the examination of subjects' reports of family environments. We also attempted to refine previous findings of such relationships by adding an additional psychiatric contrast group. Subjects included patients with the following diagnoses: (1) Anorexia nervosa, restrictor type; (2) anorexia nervosa with bulimic features; (3) normal weight bulimia; and, as a psychiatric control population (4) major depression. In contrast to previous findings, subjects in each diagnostic group do not differ statistically either from each other or from a normative population with regard to reported family environments. However, when we grouped subjects by self-reported level of depression, those with a high level of depression described family environments that are significantly different, independent of the severity of illnesses or diagnoses. We discuss the use of self-report instruments in measuring such complex phenomena as family environment.

Function of the adrenal cortex in patients with major depression

Failure to suppress cortisol secretion after administration of dexamethasone occurs in up to 50% of depressed patients. To test whether this hypothalamic-pituitary-adrenal (HPA) overactivity is associated with adrenocortical hyperresponsiveness, we performed dexamethasone suppression tests (DSTs) and adrenocorticotropic hormone (ACTH) stimulation tests in depressed subjects and subjects with other psychiatric disorders. Three groups were defined: depressed nonsuppressors, depressed suppressors, and other suppressors. While predexamethasone and postdexamethasone cortisol concentrations were greater in the depressed nonsuppressor group, ACTH concentrations did not differ among groups. After receiving alpha-ACTH[1-24] (4.2 micrograms/kg), depressed nonsuppressors had greater increases in stimulated cortisol secretion than the other groups. These results demonstrate that in a subgroup of depressed patients, HPA overactivity is associated with adrenocortical hyperresponsiveness.
