ABSTRACT 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.
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.
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.
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.

    ABSTRACT: Background. Psychodynamic psychotherapy is a psychological treatment approach that has a growing empirical base. Research has indicated an association between therapist-facilitated affective experience and outcome in psychodynamic therapy. Affect-phobia therapy (APT), as outlined by McCullough et al., is a psychodynamic treatment that emphasizes a strong focus on expression and experience of affect. This model has neither been evaluated for depression nor anxiety disorders in a randomized controlled trial. While Internet-delivered psychodynamic treatments for depression and generalized anxiety disorder exist, they have not been based on APT. The aim of this randomized controlled trial was to investigate the efficacy of an Internet-based, psychodynamic, guided self-help treatment based on APT for depression and anxiety disorders.Methods. One hundred participants with diagnoses of mood and anxiety disorders participated in a randomized (1:1 ratio) controlled trial of an active group versus a control condition. The treatment group received a 10-week, psychodynamic, guided self-help treatment based on APT that was delivered through the Internet. The treatment consisted of eight text-based treatment modules and included therapist contact (9.5 min per client and week, on average) in a secure online environment. Participants in the control group also received online therapist support and clinical monitoring of symptoms, but received no treatment modules. Outcome measures were the 9-item Patient Health Questionnaire Depression Scale (PHQ-9) and the 7-item Generalized Anxiety Disorder Scale (GAD-7). Process measures were also included. All measures were administered weekly during the treatment period and at a 7-month follow-up.Results. Mixed models analyses using the full intention-to-treat sample revealed significant interaction effects of group and time on all outcome measures, when comparing treatment to the control group. A large between-group effect size of Cohen’s d = 0.77 (95% CI: 0.37–1.18) was found on the PHQ-9 and a moderately large between-group effect size d = 0.48 (95% CI: 0.08–0.87) was found on the GAD-7. The number of patients who recovered (had no diagnoses of depression and anxiety, and had less than 10 on both the PHQ-9 and the GAD-7) were at post-treatment 52% in the treatment group and 24% in the control group. This difference was significant, χ2(N = 100, d f = 1) = 8.3, p < .01. From post-treatment to follow-up, treatment gains were maintained on the PHQ-9, and significant improvements were seen on the GAD-7.Conclusion. This study provides initial support for the efficacy of Internet-delivered psychodynamic therapy based on the affect-phobia model in the treatment of depression and anxiety disorders. The results support the conclusion that psychodynamic treatment approaches may be transferred to the guided self-help format and delivered via the Internet.

    ABSTRACT: Longitudinal data of psychotherapy theoretical orientations (PTO) for faculty from within clinical psychology programs were analyzed for a period of over two decades. Results from multilevel modeling demonstrated that clinical psychology has moved from a field that was relatively balanced in percentages of faculty from cognitive-behavioral (CBT), psychodynamic, humanistic, behavioral, and family PTOs to one that has shown highly significant linear growth for a single PTO: CBT. All other PTOs (except family) showed significant linear decline. To some extent, important research findings from other PTOs have been co-opted into CBT, but essential aspects of this work have been stripped down, muddied, or lost in a conflation with CBT treatments. We suggest that the field has lost significant intellectual diversity during the past two decades and identify how intellectual monocultures have been damaging to the success of other scientific disciplines and research groups. Tangible solutions are offered to correct this trend, including the establishment of an intellectual diversity task force, the APA's dissuasion of the establishment of monocultures within its evaluation of training, increased support for research investigation of more diverse approaches to psychotherapy, organizing of minority PTOs in order to lobby for larger research and professional training goals, and increased mentoring opportunities from minority PTO faculty.

    ABSTRACT: This article presents the results of a qualitative analysis of interviews with 25 psychologists in independent practice, investigating everyday treatment decisions and attitudes about treatment outcome research and empirically supported treatments (ESTs). Clinicians noted positive aspects about treatment outcome research, such as being interested in what works. However, they had misgivings about the application of controlled research findings to their practices, were skeptical about using manualized protocols, and expressed concern that nonpsychologists would use EST lists to dictate practice. Clinicians reported practicing in an eclectic framework, and many reported including cognitive-behavioral elements in their practice. To improve their practice, they reported valuing clinical experience, peer networks, practitioner-oriented books, and continuing education when it was not too basic. Time and financial barriers concerned nearly all participants. Clinicians suggested they might be interested in ESTs if they could integrate them into their current frameworks, and if resources for learning ESTs were improved.
