Long-term effects of short-term psychodynamic psychotherapy and cognitive-behavioural therapy in generalized anxiety disorder: 12-month follow-up.

OBJECTIVE: In a previous randomized controlled trial (RCT), short-term efficacy of cognitive-behavioural therapy (CBT) and short-term psychodynamic psychotherapy (STPP) in generalized anxiety disorder (GAD) was demonstrated. In this article, long-term stability of these effects will be examined. Effects of CBT and STPP will be compared. METHOD: In the original RCT, patients with GAD were treated with either CBT (n = 29) or STPP (n = 28). Treatments were carried out according to manuals and included up to 30 sessions. As the primary outcome measure the Hamilton Anxiety Rating Scale was used. In addition to short-term outcome previously reported, treatment effects were assessed 12 months after termination of treatment. RESULTS: Both CBT and STPP yielded large improvements at 12-month follow-up. No significant differences were found between treatments concerning the primary outcome measure. This result was corroborated by 3 self-report measures of anxiety. However, in measures of trait anxiety and worry, CBT was superior. Concerning depression, differences reported at posttreatment were no longer significant at 12-month follow-up. CONCLUSIONS: In GAD, both CBT and STPP yield large and stable effects 12 months after treatment. Concerning trait anxiety and worry, CBT seems to be superior. For STPP, further studies should be carried out to confirm the results.

[The generalized anxiety disorder--disease pattern, diagnostics and therapy]. / Die Generalisierte Angststörung - Krankheitsbild, Diagnostik und Therapie.

OBJECTIVES AND METHODS: The Generalized Anxiety Disorder (GAD) is probably the most frequent anxiety disorder, demonstrating a chronic course and severe psychosocial impairments. GAD is seldom diagnosed in practice and research on GAD has in the past been sparse. This may be linked to the less dramatic symptomatology and the diagnostic criteria which were first clearly defined by DSM-IIIR and ICD-10. This article reviews diagnostics, epidemiology and current research on psychotherapy in GAD. RESULTS AND CONCLUSIONS: Whereas cognitive-behavioral therapy (CBT) is regarded as empirically supported treatment, controlled and manualized studies of psychodynamic therapy in GAD do not exist. However, the results obtained thus far are promising. There is a definite need for further research in this area. Finally, we present an ongoing randomized controlled trial which compares manualized psychodynamic therapy and CBT in GAD. In this trial, efficacy and mechanisms of change (fearful cognitions vs. Core Conflictual Relationship Theme) in both therapies are being evaluated.

Interpersonal subtypes and change of interpersonal problems in the treatment of patients with generalized anxiety disorder: a pilot study.

Interpersonal problems are highly relevant to the treatment of generalized anxiety disorder (GAD) patients. Previous studies using the Inventory of Interpersonal Problems identified several interpersonal subtypes in GAD patients. In this study, we wanted to replicate earlier findings of interpersonal subtypes in GAD. We investigated whether these interpersonal subtypes are characterized by different types of interpersonal problems and different levels of interpersonal distress, and we further examined whether they differed with regard to improvement of interpersonal problems after short-term treatment. This study is based on results from a randomized controlled trial that investigated short-term treatments in GAD outpatients. For secondary analysis, interpersonal subtypes were identified by cluster analysis and Inventory of Interpersonal Problems profiles were calculated for both the total sample (N = 52) and the interpersonal subtypes using the Structural Summary Method for Circumplex Data. This study confirmed previous results demonstrating the existence of interpersonal subtypes in GAD. Four interpersonal subtypes were identified: Overly Nurturant, Intrusive, Socially Avoidant, and Nonassertive. Short-term treatment significantly improved interpersonal problems (d = 0.46) within the total GAD sample. Interestingly, the effect sizes of the four clusters differed considerably (d = 0.19-1.24) and the clusters displayed different changes in the two circumplex axes Dominance and Nurturance. Our study indicates that change of interpersonal problems needs to be specifically analyzed, even within homogenous diagnostic groups.

Short-term psychodynamic psychotherapy and cognitive-behavioral therapy in generalized anxiety disorder: a randomized, controlled trial.

OBJECTIVE: While several studies have shown that cognitive-behavioral therapy (CBT) is an efficacious treatment for generalized anxiety disorder, few studies have addressed the outcome of short-term psychodynamic psychotherapy, even though this treatment is widely used. The aim of this study was to compare short-term psychodynamic psychotherapy and CBT with regard to treatment outcome in generalized anxiety disorder. METHOD: Patients with generalized anxiety disorder according to DSM-IV were randomly assigned to receive either CBT (N=29) or short-term psychodynamic psychotherapy (N=28). Treatments were carried out according to treatment manuals and included up to 30 weekly sessions. The primary outcome measure was the Hamilton Anxiety Rating Scale, which was applied by trained raters blind to the treatment conditions. Assessments were carried out at the completion of treatment and 6 months afterward. RESULTS: Both CBT and short-term psychodynamic psychotherapy yielded significant, large, and stable improvements with regard to symptoms of anxiety and depression. No significant differences in outcome were found between treatments in regard to the primary outcome measure. These results were corroborated by two self-report measures of anxiety. In measures of trait anxiety, worry, and depression, however, CBT was found to be superior. CONCLUSIONS: The results suggest that CBT and short-term psychodynamic psychotherapy are beneficial for patients with generalized anxiety disorder. In future research, large-scale multicenter studies should examine more subtle differences between treatments, including differences in the patients who benefit most from each form of therapy.
