Objective: Randomized comparisons of acceptance-based treatments with traditional cognitive behavioral therapy (CBT) for anxiety disorders are lacking. To address this gap, we compared acceptance and commitment therapy (ACT) to CBT for heterogeneous anxiety disorders. Method: One hundred twenty-eight individuals (52% female, mean age = 38, 33%…

Objective: To examine whether there are latent trajectory classes in response to treatment and whether they moderate the effects of medication versus psychotherapy. Method: Data come from a 1-year randomized controlled trial of 267 low-income, young (M = 29 years), minority (44% Black, 50% Latina, 6% White) women with current major depression…

Objective: The authors compared symptom change trajectories and treatment outcome categories in children and adolescents receiving routine outpatient mental health services in a public community mental health system and a private managed care organization. Method: Archival longitudinal outcome data from parents completing the Youth Outcome…

Objective: Video teleconferencing (VTC) is used for mental health treatment delivery to geographically remote, underserved populations. However, few studies have examined how VTC affects individual or group psychotherapy processes. This study compares process variables such as therapeutic alliance and attrition among participants receiving anger…

Traumatic stress due to conflict and war causes major mental health problems in many resource-poor countries. The objective of this study was to examine whether trained lay counselors can carry out effective treatment of posttraumatic stress disorder (PTSD) in a refugee settlement. In a randomized controlled dissemination trial in Uganda with 277…

Drew 85 outcome studies from 9 journals from 1984 through 1986. Examined data in each article to provide estimates of effect sizes and to evaluate statistical power at posttreatment and follow-up. Findings indicated that power of studies to detect differences between treatment and no treatment was generally quite adequate given relatively large…

This study followed treatment responders from a randomized controlled trial of adults with major depression. Patients treated with medication but withdrawn onto pill-placebo had more relapse through 1 year of follow-up compared to patients who received prior behavioral activation, prior cognitive therapy, or continued medication. Prior…

Examined whether efficacy of psychotherapy is enhanced when clients are required to pay for treatment by comparing patients who paid for treatment with those whose payments were covered by a grant. Results revealed no reliable difference in outcomes of clients who paid and those who did not. (Author/NB)

This study estimates pretreatment-posttreatment effect size benchmarks for the treatment of major depression in adults that may be useful in evaluating psychotherapy effectiveness in clinical practice. Treatment efficacy benchmarks for major depression were derived for 3 different types of outcome measures: the Hamilton Rating Scale for Depression…

Studied processes and outcomes of psychoanalysis and psychoanalytic psychotherapy. Followed 42 subjects over natural course of treatment, with 100 percent follow-up 2-3 years posttermination. Some follow-ups extended over 30-year study. Psychoanalysis achieved more limited outcomes than predicted; psychotherapies often achieved more than…

Although the subject has been debated and examined for more than 3 decades, it is still not clear whether all psychotherapies are equally efficacious. The authors conducted 7 meta-analyses (with a total of 53 studies) in which 7 major types of psychological treatment for mild to moderate adult depression (cognitive-behavior therapy, nondirective…

Considers multiple design issues and strategies raised by comparative outcome studies including the conceptualization, implementation, and evaluation of alternative treatments; assessment of treatment-specific processes and outcomes; and evaluation of the results. (Author/BL)

An examination of the scientific basis of both control group designs and comparative designs in outcome research reveals that comparative designs generally have fewer threats to validity and provide a more efficient means of control for nonspecific treatment factors suggesting that comparative studies warrant a larger role in the study of…

Compared 93 children and adolescents who completed psychotherapy with 60 who dropped out after intake. At intake, groups did not differ on demographic, family, or clinical measures, including Child Behavior Checklist (CBCL) scores. Six months and one year later, groups were compared again. No comparison showed significant main effects of therapy.…

Used archival records to compare therapy process in 30 brief psychodynamic and 32 cognitive-behavioral therapies. Analyses of verbatim transcripts of 186 treatment sessions demonstrated that, although some features were common to both treatments, there were important differences. Identified what types of processes led to patient improvement in…
