Addressing neuroticism in psychological treatment

Neuroticism has long been associated with psychopathology and there is increasing evidence that this trait represents a shared vulnerability responsible for the development and maintenance of a range of common mental disorders. Given that neuroticism may be more malleable than previously thought, targeting this trait in treatment, rather than its specific manifestations (e.g., anxiety, mood, and personality disorders), may represent a more efficient and cost-effective approach to psychological treatment. The goals of the current manuscript are to (a) review the role of neuroticism in the development of common mental disorders, (b) describe the evidence of its malleability, and (c) review interventions that have been explicitly developed to target this trait in treatment. Implications for shifting the focus of psychological treatment to underlying vulnerabilities, such as neuroticism, rather than on the manifest symptoms of mental health conditions, are also discussed.First author draf

Experimental Manipulations to Test Theory-Driven Mechanisms of Cognitive Behavior Therapy

Despite decades of randomized-controlled trials demonstrating the efficacy of cognitive-behavior therapy (CBT), the mechanisms by which CBT achieves its effects remain unclear. Here, we describe how one adaptive intervention, the sequential multiple assignment randomized trial (SMART), can be used to randomize patients at multiple decision points in treatment to draw stronger causal claims about mechanisms unfolding in the course of CBT. We illustrate this design using preliminary data and case examples from an ongoing SMART in which we are testing the role of aversive reactions to negative emotions as a hypothesized mechanism of change in the Unified Protocol. Finally, we address common concerns with SMARTs and highlight how mechanistic research serves to personalize and optimize the delivery of CBT

A functional analysis of two transdiagnostic, emotion-focused interventions on nonsuicidal self-injury

OBJECTIVE: Nonsuicidal self-injury (NSSI) is prevalent and associated with clinically significant consequences. Developing time-efficient and cost-effective interventions for NSSI has proven difficult given that the critical components for NSSI treatment remain largely unknown. The aim of this study was to examine the specific effects of mindful emotion awareness training and cognitive reappraisal, 2 transdiagnostic treatment strategies that purportedly address the functional processes thought to maintain self-injurious behavior, on NSSI urges and acts. METHOD: Using a counterbalanced, combined series (multiple baseline and data-driven phase change) aggregated single-case experimental design, the unique and combined impact of these 2 4-week interventions was evaluated among 10 diagnostically heterogeneous self-injuring adults. Ecological momentary assessment was used to provide daily ratings of NSSI urges and acts during all study phases. RESULTS: Eight of 10 participants demonstrated clinically meaningful reductions in NSSI; 6 participants responded to 1 intervention alone, whereas 2 participants responded after the addition of the alternative intervention. Group analyses indicated statistically significant overall effects of study phase on NSSI, with fewer NSSI urges and acts occurring after the interventions were introduced. The interventions were also associated with moderate to large reductions in self-reported levels of anxiety and depression, and large improvements in mindful emotion awareness and cognitive reappraisal skills. CONCLUSIONS: Findings suggest that brief mindful emotion awareness and cognitive reappraisal interventions can lead to reductions in NSSI urges and acts. Transdiagnostic, emotion-focused therapeutic strategies delivered in time-limited formats may serve as practical yet powerful treatment approaches, especially for lower-risk self-injuring individuals.Dr. Barlow receives royalties from Oxford University Press, Guilford Publications Inc., Cengage Learning, and Pearson Publishing.

A Preliminary Evaluation of the Unified Protocol among Trauma-Exposed Adults with and without PTSD

The purpose of this study was to evaluate whether the Unified Protocol (UP)—a mechanistically transdiagnostic psychological treatment—provides benefit to individuals with a range of trauma histories, psychological difficulties, and diagnostic comorbidity. Using data from a sequential multiple-assignment randomized trial (SMART), this exploratory analysis included a sample of 69 community-recruited adults seeking outpatient mental health treatment. We examined reductions in anxiety and depressive symptoms and changes in aversive and avoidant reactions to intense emotions—the UP’s putative mechanism—first by comparing individuals with and without trauma histories and then specifically among participants with PTSD. Findings suggest that the UP may lead to similar improvements in clinical diagnostic severity, anxiety, and depression among patients with trauma exposure as those without trauma exposure. Roughly half of participants with PTSD demonstrated reductions in PTSD clinical severity, anxiety, depression, and distress aversion, suggesting the UP may be an efficacious treatment for people with PTSD and comorbid conditions

Current definitions of “transdiagnostic” in treatment development: A search for consensus

Research in psychopathology has identified psychological processes that are relevant across a range of Diagnostic and Statistical Manual (DSM) mental disorders, and these efforts have begun to produce treatment principles and protocols that can be applied transdiagnostically. However, review of recent work suggests that there has been great variability in conceptions of the term “transdiagnostic” in the treatment development literature. We believe that there is value in arriving at a common understanding of the term “transdiagnostic.” The purpose of the current manuscript is to outline three principal ways in which the term “transdiagnostic” is currently used, to delineate treatment approaches that fall into these three categories, and to consider potential advantages and disadvantages of each approachFirst author draf

Experiential avoidance as a mechanism of change across cognitive-behavioral therapy in a sample of participants with heterogeneous anxiety disorders

Despite the substantial evidence that supports the efficacy of cognitive-behavioral therapy for the treatment of anxiety and related disorders, our understanding of mechanisms of change throughout treatment remains limited. The goal of the current study was to examine changes in experiential avoidance across treatment in a sample of participants (N = 179) with heterogeneous anxiety disorders receiving various cognitive-behavioral therapy protocols. Univariate latent growth curve models were conducted to examine change in experiential avoidance across treatment, followed by parallel process latent growth curve models to examine the relationship between change in experiential avoidance and change in anxiety symptoms. Finally, bivariate latent difference score models were conducted to examine the temporal precedence of change in experiential avoidance and change in anxiety. Results indicated that there were significant reductions in experiential avoidance across cognitive-behavioral treatment, and that change in experiential avoidance was significantly associated with change in anxiety. Results from the latent difference score models indicated that change in experiential avoidance preceded and predicted subsequent changes in anxiety, whereas change in anxiety did not precede and predict subsequent changes in experiential avoidance. Taken together, these results provide additional support for reductions in experiential avoidance as a transdiagnostic mechanism in cognitive-behavioral therapy.First author draf

Expectancies, working alliance, and outcome in transdiagnostic and single diagnosis treatment for anxiety disorders: an investigation of mediation

Patients’ outcome expectancies and the working alliance are two psychotherapy process variables that researchers have found to be associated with treatment outcome, irrespective of treatment approach and problem area. Despite this, little is known about the mechanisms accounting for this association, and whether contextual factors (e.g., psychotherapy type) impact the strength of these relationships. The primary aim of this study was to examine whether patient-rated working alliance quality mediates the relationship between outcome expectancies and pre- to post-treatment change in anxiety symptoms using data from a recent randomized clinical trial comparing a transdiagnostic treatment (the Unified Protocol [UP]; Barlow et al., Unified protocol for transdiagnostic treatment of emotional disorders: Client workbook, Oxford University Press, New York, 2011a; Barlow et al., Unified protocol for transdiagnostic treatment of emotional disorders: Patient workbook. New York: Oxford University Press, 2017b) to single diagnosis protocols (SDPs) for patients with a principal heterogeneous anxiety disorder (n = 179). The second aim was to explore whether cognitive-behavioral treatment condition (UP vs. SDP) moderated this indirect relationship. Results from mediation and moderated mediation models indicated that, when collapsing across the two treatment conditions, the relationship between expectancies and outcome was partially mediated by the working alliance [B = 0.037, SE = 0.05, 95% CI (.005, 0.096)]. Interestingly, within-condition analyses showed that this conditional indirect effect was only present for SDP patients, whereas in the UP condition, working alliance did not account for the association between expectancies and outcome. These findings suggest that outcome expectancies and working alliance quality may interact to influence treatment outcomes, and that the nature and strength of the relationships among these constructs may differ as a function of the specific cognitive-behavioral treatment approach utilized.This study was funded by grant R01 MH090053 from the National Institutes of Health.

Efficacy of the Unified Protocol for transdiagnostic treatment of comorbid psychopathology accompanying emotional disorders compared to treatments targeting single disorders

OBJECTIVE: This study aimed to examine whether the Unified Protocol (UP), a transdiagnostic cognitive-behavioral therapy for emotional disorders (i.e., anxiety, mood, and related disorders), is efficacious in the treatment of co-occurring emotional disorders compared to established single disorder protocols (SDPs) that target specific disorders (e.g., panic disorder). METHOD: Participants included 179 adults seeking outpatient psychotherapy. Participant age ranged from 18 to 66 years, with an average of 30.66 years (SD = 10.77). The sample was 55% female and mostly Caucasian (83%). Diagnostic assessments were completed with the Anxiety Disorder Interview Schedule (ADIS), and disorder-specific, clinician-rated measures for the comorbid diagnoses of interest. RESULTS: In both treatment conditions, participants' mean number of diagnoses dropped significantly from baseline to posttreatment, and baseline to 12-month follow-up. Additionally, large effects were observed for changes in comorbid generalized anxiety (ESɢ: UP = −1.72; SDP = −1.98), social anxiety (ESɢ: UP = −1.33, −0.86; SDP = −1.60, −1.54), and depression (ESɢ: UP = −0.83; SDP = −0.84). Significant differences were not observed in between-group comparisons. CONCLUSIONS: Results suggest that both the UP and SDPs are efficacious in reducing symptoms of comorbid emotional disorders. The clinical, practical, and cost-effective advantages of transdiagnostic CBT are discussed.Please note the following financial disclosures/conflicts of interest: Dr. Barlow reported receiving royalties from Oxford University Press, United Kingdom (which includes royalties for the treatment manuals included in this study); Guilford Publications Inc., United States; Cengage Learning, United States; Pearson Publishing, United Kingdom.

Development of a single-session, transdiagnostic preventive intervention for young adults at risk for emotional disorders

Cognitive-behavioral prevention programs have demonstrated efficacy in reducing subclinical symptoms of anxiety and depression, and there is some evidence to suggest that they can lower the risk of future disorder onset. However, existing interventions tend to be relatively lengthy and target specific disorders or problem areas, both of which limit their potential for widespread dissemination. To address these limitations, we aimed to develop a single-session, transdiagnostic preventive intervention based on the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders for young adults at risk for developing anxiety and/or depressive disorders within a college setting. Results from this proof-of-concept study indicated that the intervention was viewed as highly satisfactory and acceptable. The intervention also was successful at delivering adaptive emotion management skills in its 2-hr workshop format. Future studies evaluating the efficacy of this novel transdiagnostic, emotion-focused prevention program are warranted.Accepted manuscrip

Treating depressive disorders with the unified protocol: A preliminary randomized evaluation.

OBJECTIVES: This study aims to examine the efficacy of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) for individuals diagnosed with a depressive disorder. METHOD: Participants included 44 adults who met criteria for major depressive disorder, persistent depressive disorder, or another specified depressive disorder according to the Anxiety Disorder Interview Schedule (ADIS). These individuals represent a subset of patients from a larger clinical trial comparing the UP to single-disorder protocols (SDPs) for discrete anxiety disorders and a waitlist control (WLC) condition (Barlow et al., 2017); inclusion criteria for the parent study required participants to have a principal anxiety disorder. RESULTS: Significant reductions in depressive symptoms were observed within the UP condition across clinician-rated and self-report measures of depression from baseline to post-treatment, as well as to the 12-month follow-up assessment. Compared to the WLC group, individuals in the UP condition demonstrated significantly lower levels on our continuous, clinician-rated measure of depressive symptoms at post-treatment. There were no differences between the UP and SDP conditions on depressive symptoms at post-treatment or at the 12-month follow-up timepoint. CONCLUSIONS: In this exploratory set of analyses, the UP evidenced efficacy for reduction of depressive symptoms, adding to the growing support for its utility in treating depression.R01 MH090053 - NIMH NIH HHSAccepted manuscrip
