Impact of Baseline Characteristics on the Effectiveness of Disorder-Specific Cognitive Behavioral Analysis System of Psychotherapy (CBASP) and Supportive Psychotherapy in Outpatient Treatment for Persistent Depressive Disorder.

ABSTRACT: Importance: In the treatment of persistent depressive disorder (PDD), disorder-specific Cognitive Behavioral Analysis System of Psychotherapy (CBASP) has been shown to be superior to Supportive Psychotherapy (SP) in outpatients. It remains to clear which subgroups of patients benefit equally and differentially from both psychotherapies. Objective: To identify those patient-level baseline characteristics that predict a comparable treatment effectiveness of CBASP and SP and those that moderate the differential effectiveness of CBASP compared to SP. Design, setting and participants: In this analysis of a 48-week multicenter randomized clinical trial comparing CBASP to SP in adult antidepressant-free outpatients with early-onset PDD, we evaluated baseline variables from the following domains as potential predictors and moderators of treatment effectiveness: socio-demography, clinical status, psychosocial and global functioning, life quality, interpersonal problems, childhood trauma, treatment history, preference for psychotherapy, and treatment expectancy. Interventions: A 48-week treatment program with 32 sessions of either CBASP or SP. Main outcomes and measures: Depression severity measured by the 24-item Hamilton Rating Scale for Depression (HRSD-24) at week 48. Results: From N = 268 randomized outpatients, N = 209 completed the 48-week treatment program. CBASP completers had significantly lower post-treatment HRSD-24 scores than SP completers (mean_CBASP=13.96, sd_CBASP= 9.56; mean_SP= 16.69, sd_SP= 9.87; p = 0.04). A poor response to both therapies was predicted by higher baseline levels of clinician-rated depression, elevated suicidality, comorbid anxiety, lower social functioning, higher social inhibition, moderate-to-severe early emotional or sexual abuse, no preference for psychotherapy, and the history of at least one previous inpatient treatment. Moderator analyses revealed that patients with higher baseline levels of self-rated depression, comorbidity of at least one Axis-I disorder, self-reported moderate-to-severe early emotional or physical neglect, or at least one previous antidepressant treatment, had a significantly lower post-treatment depression severity with CBASP compared to SP (all p < 0.05). Conclusions and relevance: A complex multifactorial interaction between severe symptoms of depression, suicidality, and traumatic childhood experiences characterized by abuse, social inhibition, and anxiety may represent the basis of non-response to psychotherapy in patients with early onset PDD. Specific psychotherapy with CBASP might, however, be more effective and recommendable for a variety of particularly burdened patients compared to SP.

Project description:PurposeBreast cancer (BC) is a risk factor for major depressive disorder (MDD), yet little research has tested the efficacy of different psychotherapies for depressed women with BC. This study, the largest to date, compared outcomes of three evidence-based, 12-week therapies in treating major depressive disorder among women with breast cancer.MethodsThis randomized trial compared interpersonal psychotherapy (IPT), problem solving therapy (PST), and brief supportive psychotherapy (BSP). Conducted at the outpatient clinic of the New York State Psychiatric Institute/Columbia University, the trial offered bilingual treatment by treatment-specific psychotherapists supervised by treatment experts. The primary outcome was change in the Hamilton Depression Rating Scale (HAM-D) at 12 weeks. Secondary outcomes included other validated patient-reported outcomes for depression and quality of life.ResultsOf 179 women with breast cancer screening positive for depression at the Columbia Cancer Center, 134 eligible patients signed informed treatment consent. Half of patients were Hispanic and economically disadvantaged. Most women had stage I (35.2%) or II (36.9%) BC; 9% had stage IV. The three brief psychotherapies showed similar improvements on the HAM-D, with large pre-post effect sizes (d ~ 1.0); a priori defined response rates were 35% for IPT, 50% for PST and 31% for BSP, and remission rates 25%, 30% and 27%, respectively. The three treatments also showed similar improvements in the Quality of Life Enjoyment and Satisfaction Questionnaire. Dropout was high, ranging from 37 to 52% across treatments. Predictors of dropout included having < 16 years of education and annual family income < $20,000.ConclusionsAmong patients who completed treatment, all three psychotherapies were associated with similar, meaningful improvements in depression. Physical distance between the oncology and psychiatric treatment sites might have contributed to high dropout. This study suggests various psychotherapy approaches may benefit patients with breast cancer and major depression.

Project description:ImportanceCognitive behavioral therapy (CBT), the best-studied treatment for body dysmorphic disorder (BDD), has to date not been compared with therapist-delivered supportive psychotherapy, the most commonly received psychosocial treatment for BDD.ObjectiveTo determine whether CBT for BDD (CBT-BDD) is superior to supportive psychotherapy in reducing BDD symptom severity and associated BDD-related insight, depressive symptoms, functional impairment, and quality of life, and whether these effects are durable.Design, setting, and participantsThis randomized clinical trial conducted at Massachusetts General Hospital and Rhode Island Hospital recruited adults with BDD between October 24, 2011, and July 7, 2016. Participants (n = 120) were randomized to the CBT-BDD arm (n = 61) or the supportive psychotherapy arm (n = 59). Weekly treatments were administered at either hospital for 24 weeks, followed by 3- and 6-month follow-up assessments. Measures were administered by blinded independent raters. Intention-to-treat statistical analyses were performed from February 9, 2017, to September 22, 2018.InterventionsCognitive behavioral therapy for BDD, a modular skills-based treatment, addresses the unique symptoms of the disorder. Supportive psychotherapy is a nondirective therapy that emphasizes the therapeutic relationship and self-esteem; supportive psychotherapy was enhanced with BDD-specific psychoeducation and treatment rationale.Main outcomes and measuresThe primary outcome was BDD symptom severity measured by the change in score on the Yale-Brown Obsessive-Compulsive Scale Modified for BDD from baseline to end of treatment. Secondary outcomes were the associated symptoms and these were assessed using the Brown Assessment of Beliefs Scale, Beck Depression Inventory-Second Edition, Sheehan Disability Scale, and Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form.ResultsOf the 120 participants, 92 (76.7%) were women, with a mean (SD) age of 34.0 (13.1) years. The difference in effectiveness between CBT-BDD and supportive psychotherapy was site specific: at 1 site, no difference was detected (estimated mean [SE] slopes, -18.6 [1.9] vs -16.7 [1.9]; P = .48; d growth-modeling analysis change, -0.25), whereas at the other site, CBT-BDD led to greater reductions in BDD symptom severity, compared with supportive psychotherapy (estimated mean [SE] slopes, -18.6 [2.2] vs -7.6 [2.0]; P < .001; d growth-modeling analysis change, -1.36). No posttreatment symptom changes were observed throughout the 6 -months of follow-up (all slope P ≥ .10).Conclusions and relevanceBody dysmorphic disorder severity and associated symptoms appeared to improve with both CBT-BDD and supportive psychotherapy, although CBT-BDD was associated with more consistent improvement in symptom severity and quality of life.Trial registrationClinicalTrials.gov identifier: NCT01453439.

Project description:ContextPrevious studies have found that few chronically depressed patients remit with antidepressant medications alone.ObjectiveTo determine the role of adjunctive psychotherapy in the treatment of chronically depressed patients with less than complete response to an initial medication trial.DesignThis trial compared 12 weeks of (1) continued pharmacotherapy and augmentation with cognitive behavioral analysis system of psychotherapy (CBASP), (2) continued pharmacotherapy and augmentation with brief supportive psychotherapy (BSP), and (3) continued optimized pharmacotherapy (MEDS) alone. We hypothesized that adding CBASP would produce higher rates of response and remission than adding BSP or continuing MEDS alone.SettingEight academic sites.ParticipantsChronically depressed patients with a current DSM-IV-defined major depressive episode and persistent depressive symptoms for more than 2 years.InterventionsPhase 1 consisted of open-label, algorithm-guided treatment for 12 weeks based on a history of antidepressant response. Patients not achieving remission received next-step pharmacotherapy options with or without adjunctive psychotherapy (phase 2). Individuals undergoing psychotherapy were randomized to receive either CBASP or BSP stratified by phase 1 response, ie, as nonresponders (NRs) or partial responders (PRs).Main outcome measuresProportions of remitters, PRs, and NRs and change on Hamilton Scale for Depression (HAM-D) scores.ResultsIn all, 808 participants entered phase 1, of which 491 were classified as NRs or PRs and entered phase 2 (200 received CBASP and MEDS, 195 received BSP and MEDS, and 96 received MEDS only). Mean HAM-D scores dropped from 25.9 to 17.7 in NRs and from 15.2 to 9.9 in PRs. No statistically significant differences emerged among the 3 treatment groups in the proportions of phase 2 remission (15.0%), partial response (22.5%), and nonresponse (62.5%) or in changes on HAM-D scores.ConclusionsAlthough 37.5% of the participants experienced partial response or remitted in phase 2, neither form of adjunctive psychotherapy significantly improved outcomes over that of a flexible, individualized pharmacotherapy regimen alone. A longitudinal assessment of later-emerging benefits is ongoing.

Project description:Despite the heterogeneous symptom presentation and complex etiology of major depressive disorder (MDD), functional neuroimaging studies have shown with remarkable consistency that dysfunction in mesocorticolimbic brain systems are central to the disorder. Relatively less research has focused on the identification of biological markers of response to antidepressant treatment that would serve to improve the personalized delivery of empirically supported antidepressant interventions. In the present study, we investigated whether resting-state functional brain connectivity (rs-fcMRI) predicted response to Behavioral Activation Treatment for Depression, an empirically validated psychotherapy modality designed to increase engagement with rewarding stimuli and reduce avoidance behaviors. Twenty-three unmedicated outpatients with MDD and 20 matched nondepressed controls completed rs-fcMRI scans after which the MDD group received an average of 12 sessions of psychotherapy. The mean change in Beck Depression Inventory-II scores after psychotherapy was 12.04 points, a clinically meaningful response. Resting-state neuroimaging data were analyzed with a seed-based approach to investigate functional connectivity with four canonical resting-state networks: the default mode network, the dorsal attention network, the executive control network, and the salience network. At baseline, the MDD group was characterized by relative hyperconnectivity of multiple regions with precuneus, anterior insula, dorsal anterior cingulate cortex (dACC), and left dorsolateral prefrontal cortex seeds and by relative hypoconnectivity with intraparietal sulcus, anterior insula, and dACC seeds. Additionally, connectivity of the precuneus with the left middle temporal gyrus and connectivity of the dACC with the parahippocampal gyrus predicted the magnitude of pretreatment MDD symptoms. Hierarchical linear modeling revealed that response to psychotherapy in the MDD group was predicted by pretreatment connectivity of the right insula with the right middle temporal gyrus and the left intraparietal sulcus with the orbital frontal cortex. These results add to the nascent body of literature investigating pretreatment rs-fcMRI predictors of antidepressant treatment response and is the first study to examine rs-fcMRI predictors of response to psychotherapy.
