Randomized trial of the efficacy of trial-based cognitive therapy for obsessive-compulsive disorder: preliminary findings

Abstract Introduction Obsessive-compulsive disorder (OCD) is the fourth most prevalent mental disorder and is a disabling condition. OCD is associated with anatomical and functional changes in the brain, in addition to dysfunctional cognitions. The treatments of choice are selective serotonin reuptake inhibitors, cognitive-behavioral therapy (CBT), and exposure and response prevention (ERP). Trial-based cognitive therapy (TBCT) is a recent and empirically validated psychotherapy with a focus on restructuring dysfunctional negative core beliefs (CBs). The objective of this study was to evaluate the efficacy of TBCT relative to ERP for treatment of OCD. Methods A randomized, single-blind clinical trial was conducted, randomizing 26 patients for individual treatment with TBCT (n = 12) or ERP (n = 14). The groups were evaluated at baseline, at the end of 3 months (12 sessions), and at 3, 6, and 12-month follow-ups. Results Both approaches reduced the severity of symptoms with large effect sizes. These results were maintained at the 12-month follow-up assessment. Conclusion TBCT may be a valid and promising treatment for this disorder.

Changing negative core beliefs with trial-based thought record

Background: Trial-based thought record (TBTR) is a technique used in trial-based cognitive therapy (TBCT), and simulates a court trial. It was designed to restructure unhelpful core beliefs (CBs) during psychotherapy. Objective: To confirm previous findings on the efficacy of TBTR in decreasing patients' adherence to self-critical and unhelpful CBs and corresponding emotions, as well as assessing the differential efficacy of the empty-chair approach relative to the static format of TBTR. Methods: Thirty-nine outpatients were submitted to a 50-minute, one-session, application of the TBTR technique in the empty-chair (n = 18) or conventional (n = 21) formats. Patients' adherence to unhelpful CBs and the intensity of corresponding emotions were assessed after each step of TBTR, and the results obtained in each format were compared. Results: Significant reductions in percent values both in the credit given to CBs and in the intensity of corresponding emotions were observed at the end of the session (p < .001), relative to baseline values. ANCOVA also showed a significant difference in favor of the empty-chair format for both belief credit and emotion intensity (p = .04). Discussion: TBTR may help patients reduce adherence to unhelpful CBs and corresponding emotions and the empty-chair format seems to be more efficacious than the conventional format.

Changing core beliefs with trial-based cognitive therapy may improve quality of life in social phobia: a randomized study

Objective: To determine whether there are differences in quality of life (QoL) improvement after treatment with the trial-based thought record (TBTR) versus conventional cognitive therapy (CCT) in patients with social anxiety disorder (SAD). Method: A randomized trial comparing TBTR with a set of CCT techniques, which included the standard 7-column dysfunctional thought record (DTR) and the positive data log (PDL) in patients with SAD, generalized type. Results: Repeated measures analysis of variance (ANOVA) revealed a significant time effect in the general health, vitality, social functioning, and mental health domains of the Short Form 36. It also indicated significant treatment effects on the bodily pain, social functioning, role-emotional, and mental health domains, with higher scores in the TBTR group. One-way analysis of covariance (ANCOVA), using pretreatment values as covariates, showed that TBTR was associated with significantly better QoL post-treatment (bodily pain, social functioning and role-emotional) and at follow-up (role-emotional). A significant treatment effect on the role-emotional domain at 12-month follow-up denoted a sustained effect of TBTR relative to CCT. Conclusion: This study provided preliminary evidence that TBTR is at least as effective as CCT in improving several domains of QoL in SAD, specifically when the standard 7-column DTR and the PDL are used. .
