Cognitive behavior therapy (CBT) has come to be a widely practiced psychotherapy throughout the world. The present article reviews theory, history, and evidence for CBT. It is meant as an effort to summarize the forms and scope of CBT to date for the uninitiated. Elements of CBT such as cognitive therapy, behavior therapy, and so-called "third wave" CBT, such as dialectical behavior therapy (DBT) and acceptance and commitment therapy (ACT) are covered. The evidence for the efficacy of CBT for various disorders is reviewed, including depression, anxiety disorders, personality disorders, eating disorders, substance abuse, schizophrenia, chronic pain, insomnia, and child/adolescent disorders. The relative efficacy of medication and CBT, or their combination, is also briefly considered. Future directions for research and treatment development are proposed.

On average, randomized controlled trials of CBT and of psychodynamic therapy did not differ significantly in quality. In CBT trials, low quality appeared to reduce the reliability and validity of trial results. These findings highlight the importance of discerning quality in individual psychotherapy trials and also point toward specific methodological standards for the future.

This study sought to investigate the extent to which therapists endorse techniques outside of their self-identified orientation and which techniques are endorsed across orientations. A survey consisting of 127 techniques from 8 major theories of psychotherapy was administered via U.S. mail to a national random sample of doctoral-level psychotherapy practitioners. The 201 participants endorsed substantial numbers of techniques from outside their respective orientations. Many of these techniques were quite different from those of the core theories of the respective orientations. Further examining when and why experienced practitioners switch to techniques outside their primary orientation may help reveal where certain techniques fall short and where others excel, indicating a need for further research that taps the collective experience of practitioners.

Accelerated experiential dynamic psychotherapy (AEDP) is an integrative model of psychotherapy that brings together relational and experiential work, with the aim of not only alleviating suffering but also bringing about flourishing. The present study took place within a developing AEDP practice research network and examined outcomes for 62 self-referred adults treated using a 16-session format of AEDP treatment. Participants completed self-report measures before and following treatment. Measures assessed a variety of psychological problems, subjective distress, as well as aspects of positive psychological functioning. Treatment occurred in naturalistic independent practice outpatient settings in the United States, Canada, Israel, Japan, and Sweden. Large effect sizes (d Ͼ 0.80) were obtained for clinical problems and subjective distress. The majority of patients evidenced clinically reliable change according to Jacobson, Roberts, Berns, and McGlinchey's (1999) criteria. Effectiveness was further examined by dividing the sample into a clinical group with pervasive and severe problems and a subclinical group with fewer problems and mild severity. Within the clinical group, total and global scores on all measures improved significantly following treatment. Effect sizes were d Ͼ 1.00 for all scales. The subclinical group also demonstrated significant improvements, with effect sizes ranging from d ϭ 0.46 to d ϭ 2.07. These results provide initial empirical support for the effectiveness of AEDP as a model of therapy that can effect meaningful and significant improvements across a range of psychological symptoms. Clinical Impact StatementQuestion: This study examines the effectiveness of accelerated experiential dynamic psychotherapy (AEDP), a transdiagnostic treatment for psychological problems and positive psychological functioning in independent practice settings. Clinical researchers and practitioners partnered in the development of an AEDP practice research network (PRN) model. Findings: Findings support the use of AEDP for a range of presenting problems and symptoms. Meaning: Results support the clinical application of AEDP across a variety of psychological problems and functionings and ongoing research using a PRN model. Next Steps: Future research will continue AEDP PRN initiatives and partnerships in independent practice settings and will investigate maintenance of therapeutic gains over a 6-and 12-month follow-up period.
