Mechanism engagement as a potential evidence-based approach to personalized treatment termination.

Objective: This study explores whether early change on a putative mechanism maintaining symptoms can serve as a proximal indicator of response to prompt discontinuation. Method: Patients (N = 70; Mage = 33.74, 67% female, 74% white) with heterogeneous anxiety and depressive disorders completed a sequential multiple assignment randomized trial (SMART). Patients received 6 sessions of skill modules from the Unified Protocol and then underwent a second-stage randomization to either receive the remaining 6 sessions (Full duration) or discontinue treatment (Brief duration). All participants completed weekly self-report measures of anxiety and depressive symptoms and distress aversion for the full 12-week treatment window. We used structural equation modeling to test (1) if distress aversion demonstrated significant variability during the first-stage randomization and (2) if distress aversion during the first-stage randomization predicted second-stage changes in anxiety and depression. Results: Participants demonstrated significant variability in first-stage distress aversion. Latent distress aversion slopes significantly predicted latent second-stage anxiety slopes, whereas latent distress aversion intercepts significantly predicted latent second-stage depression slopes. Conclusions: These results suggest that early mechanism engagement may have potential as a trigger to prompt personalized termination. Shorter courses of care may reduce patient costs and increase the mental health service system's capacity.

Within-person changes in aversive reactivity predict session-to-session reductions in anxiety and depression in the unified protocol.

ABSTRACTThe Unified Protocol (UP) theoretically leads to reductions in emotional disorder symptoms by reducing aversive reactions to emotions. However, aversive reactions can take many forms (e.g., non-acceptance, behavioral avoidance). We examined if (1) multiple aspects of aversive reactivity predicted session-to-session changes in anxiety and depression in the UP, (2) these aspects reflected a single latent construct, and (3) changes in this latent construct predicted changes in anxiety and depression. Participants (N = 70, Mage = 33.74, 67.1% female, 74.3% white) completed six sessions of UP modules and measures of aversive reactivity, anxiety, and depression before each session. We used hierarchical linear modeling and random-intercept cross-lagged panel models to test aspects of aversive reactivity and a latent factor of aversive reactivity, respectively, as predictors of session-to-session changes in anxiety and depression. Within-person improvements in four of five aspects of aversive reactivity predicted decreases in anxiety, and improvements in two aspects predicted decreases in depression. However, within-person improvements in latent aversive reactivity predicted decreases in anxiety at five sessions and in depression across all sessions. These results add to the growing literature highlighting the role of aversive reactivity as a potential transdiagnostic process involved in improvements in emotional disorder symptoms during treatment.

Integrating and differentiating personality and psychopathology in cognitive behavioral therapy.

A large body of literature supports the strong association between personality features and psychopathology. This research has, however, had little influence on day-to-day therapeutic practice, particularly in cognitive behavioral approaches that have traditionally focused on addressing the symptoms of categorically defined diagnoses. Indeed, there are few CBT protocols aimed at altering the personality features. Recently, however, the CBT literature has displayed an increased focus on identifying alternative higher-order, dimensional mechanisms that may underscore the development and maintenance of broad classes of psychopathology (e.g., aversive reactivity to emotions, reward sensitivity, and performance expectancies). There is ample evidence linking these processes to DSM disorder severity; however, they may also represent a functional link between the personality domains and the disorder symptoms organized beneath them. The functional mechanisms through which an individual's personality confers risk for psychopathology may be naturally amenable to cognitive behavioral elements, and targeting these processes in treatment has the potential to address both disorder symptoms and underlying personality vulnerabilities. Thus, the identification of intermediate functional mechanisms may help bridge the gap between personality science and clinical practice.

A SMART approach to personalized care: preliminary data on how to select and sequence skills in transdiagnostic CBT.

Given that over 20 million adults each year do not receive care for their mental health difficulties, it is imperative to improve system-level capacity issues by increasing treatment efficiency. The present study aimed to collect feasibility/acceptability data on two strategies for increasing the efficiency of cognitive behavioral therapy: (1) personalized skill sequences and (2) personalized skill selections. Participants (N = 70) with anxiety and depressive disorders were enrolled in a pilot sequential multiple assignment randomized trial (SMART). Patients were randomly assigned to receive skill modules from the Unified Protocol in one of three sequencing conditions: standard, sequences that prioritized patients' relative strengths, and sequences that prioritized relative deficits. Participants also underwent a second-stage randomization to either receive 6 sessions or 12 sessions of treatment. Participants were generally satisfied with the treatment they received, though significant differences favored the Capitalization and Full duration conditions. There were no differences in trajectories of improvement as a function of sequencing condition. There were also no differences in end-of-study outcomes between brief personalized treatment and full standard treatment. Thus, it may be feasible to deliver CBT for personalized durations, though this may not substantially impact trajectories of change in anxiety or depressive symptoms.

Skill Use Mediates the Within-Person Effect of the Alliance on Session-to-Session Changes in Anxiety and Depression in the Unified Protocol.

Objective: Both the therapeutic alliance and the specific skills taught in treatment are thought to contribute to change in cognitive-behavior therapy (CBT), but it is unclear if or how these processes influence each other and outcomes in treatment. We tested the hypothesis that the degree to which patients used CBT skills would mediate the relation between the alliance and session-to-session changes in anxiety and depression. Method: Adult participants (N = 70; Mage = 33.74, 67% female, 70% White) with emotional disorders were randomized to receive 6 or 12 sessions of the Unified Protocol. Before each session, participants reported anxiety and depression severity and past-week skillfulness. After each session, participants rated the strength of the alliance. We tested whether greater within-person skillfulness mediated the relation between within-person alliance strength and session-to-session changes in anxiety and depression. Results: Skillfulness significantly mediated the effect of the alliance on session-to-session changes in anxiety, ab = -.02, p = .04, and depression, ab = -.02, p = .02, such that a stronger alliance predicted greater next-session skillfulness, which predicted session-to-session decreases in anxiety and depression. When alliance subscales were examined separately, the strongest effect was observed for agreement on therapy tasks. Conclusions: Improvements in the alliance may facilitate skill use and indirectly predict reductions in anxiety and depression through skill use in CBT. We encourage research on how to enhance both the alliance and skillfulness in CBT.

BPD compass: A randomized controlled trial of a short-term, personality-based treatment for borderline personality disorder.

Borderline personality disorder (BPD) is a heterogeneous condition that is particularly associated with three broad personality dimensions: neuroticism (i.e., high negative affectivity), agreeableness (i.e., low antagonism), and conscientiousness (i.e., low disinhibition). The purpose of the present study was to explore whether treatment with BPD Compass, a novel personality-based intervention for BPD, results in greater reductions in BPD symptoms, neuroticism, agreeableness, and conscientiousness compared to a waitlist control (WLC) condition. We also aimed to characterize within-treatment effects for participants assigned to the BPD Compass condition and evaluate patients' satisfaction with treatment. Participants (N = 51; Mage = 28.38; 83.3% female; 93.8% White; 54.2% sexual minority) meeting DSM-5 criteria for BPD were enrolled in a randomized controlled trial to evaluate the efficacy of BPD Compass. Patients were randomly assigned to receive 18 sessions of BPD Compass or complete an 18-week waiting period. BPD Compass led to larger reductions in BPD symptoms (assessor-rated [ß = -0.47] and self-reported [ß = -0.62]) and neuroticism (ß = -0.37), but not agreeableness (ß = 0.08) or conscientiousness (ß = 0.10), compared to the WLC condition. Within the BPD Compass condition, pre- to posttreatment improvements in BPD symptoms, neuroticism, and conscientiousness were significant and large in magnitude (Hedges' gs: -1.38 to -1.08). Patients were highly satisfied with BPD Compass and generally perceived it to be an appropriate length. Thus, BPD Compass may be an accessible and useful complement to more specialty or intensive treatments for BPD. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Conceptual development and case data for a modular, personality-based treatment for borderline personality disorder.

Borderline personality disorder (BPD) is a heterogenous condition, and variations in its presentation may be accounted for by individual differences in personality dimensions. Extant treatments for BPD are long term and intensive; it is possible that prioritizing the personality-based difficulties that underlie an individual's symptoms may improve the efficiency of care. This article describes the conceptual background for the development of a novel, personality-based intervention for BPD (BPD Compass), which was informed by recent research on personality mechanisms maintainin this condition, and was designed to address gaps left by existing treatments and to be maximally efficient and disseminable. BPD Compass is a comprehensive, short-term package with a fully modular design that allows for personalization (e.g., all skills can be presented in isolation or in any order based on pretreatment assessment). We discuss the theoretical background for its development, an overview of the skills included in the treatment, as well as preliminary efficacy data.

Aversive Reactivity: A Transdiagnostic Functional Bridge Between Neuroticism and Avoidant Behavioral Coping.

Aversive reactivity to negative affect has been described as a transdiagnostic mechanism that links distal temperamental vulnerabilities to clinically relevant behaviors. However, the abundance of constructs reflecting aversive reactivity has resulted in a proliferation of models that may ultimately be redundant. We performed a circumscribed review of studies measuring associations between six constructs - anxiety sensitivity, experiential avoidance, distress intolerance, intolerance of uncertainty, thought-action fusion, and negative urgency - and ten relevant coping behaviors. Results suggested that most constructs were measured in relation to a limited number of coping behaviors. Additionally, constructs were most often measured in isolation, rather than with similar constructs. Implications and suggestions for future research and treatment are discussed.

A Day in the Life of Borderline Personality Disorder: A Preliminary Analysis of Within-Day Emotion Generation and Regulation.

In Linehan's (1993) biosocial theory, borderline personality disorder (BPD) results in part from frequent, intense, negative emotions and maladaptive behavioral responses to those emotions. We conducted a secondary data analysis of an intensive single-case experimental design to explore hourly relations among behavioral responses and emotions in BPD. Eight participants with BPD (M age = 21.57, 63% female; 63% Asian) reported their emotions and behaviors hourly on two days. Participants reported a neutral-to-negative average emotional state with substantial variability each day. This emotional state was characterized most frequently by anxiety and joy. Participants tended to "dig into", or savor, experiences of joy, but problem-solve around, push away, or accept anxiety. Acceptance predicted hour-by-hour increases in negative emotion intensity, and pushing emotions away predicted hour-by-hour increases in positive emotion intensity. These results suggest that anxiety dominates the emotional experiences of people with BPD and co-occurs with a variety of emotion regulation strategies, while joy co-occurs with strategies designed to prolong emotional experiences. Despite its general adaptiveness, acceptance may be less effective, and pushing emotions away may be more effective, than other emotion regulation strategies at improving momentary negative emotions for those with BPD. We discuss the preliminary nature of these findings and encourage future researchers to build on them in larger samples with more severe presentations of BPD.
