A Systematic Review of the Use of Acceptance and Commitment Therapy to Treat Adult Obsessive-Compulsive Disorder.

The present review aims to critically evaluate available literature on the use of acceptance and commitment therapy (ACT) to treat adult obsessive-compulsive disorder (OCD) and to draw conclusions about using ACT to reduce OCD symptoms in adults with OCD. Databases (PsycINFO, PsycARTICLES, MEDLINE, and PubMed), Google Scholar, and article references were used to identify relevant studies through October 10, 2020. This review includes both peer-reviewed, published articles (n = 15) and unpublished theses and dissertations (n = 2) to increase the breadth of the review as suggested by PRISMA guidelines. Reviewed articles utilized ACT and at least one measure of OCD symptom severity. Information on methodological, measurement, statistical, and analytical characteristics of the included studies were extracted to determine the quality of the available studies and to inform the conclusions of this review. Seventeen studies (n = 17) with 336 participants from three countries were evaluated. The current evidence suggests that ACT can be used to reduce symptoms of OCD in adults. A conclusion supporting the use of ACT to reduce OCD symptoms can be made because of several strengths within this body of literature (e.g., use of validated OCD symptom measures, inclusion of treatment manuals, use of multiple assessment points, etc.). However, because a majority of the included studies are quasi-experimental and single-subject studies, more stringent research (i.e., randomized controlled trials) with large, diverse samples is needed to strengthen this conclusion. Additionally, dismantling studies exploring the components of ACT that lead to OCD symptom improvement are needed.

Implementing Trauma-Informed Care Through a Learning Collaborative: A Theory-Driven Analysis of Sustainability.

This study investigated the sustainability of a multi-agency 15-month Learning Collaborative (LC) for implementing trauma-informed care in 23 rural Pennsylvania counties. Provider agencies (N = 22) were assessed three years following completion of the LC. Sustained trauma-informed practices were assessed through criteria indicating organizational achievement as a trauma-informed care center. A theoretical model of clinical training was applied to determine the extent to which training- and skill-related factors were associated with sustained trauma-informed care. Three years after the LC, trauma symptom screening rates and staff training improvements were sustained, while staff confidence in delivering trauma-informed care worsened across time. Sustained trauma-informed care was associated with implementation milestone completion and third-party ratings of quality improvement skills during the LC. Building capacity for organizational change through training and skill development during active phases of implementation is important for sustained trauma informed care in behavioral health service.

Correlation Between Intolerance of Uncertainty and Post-Operative Regret in Otolaryngology Patients.

OBJECTIVE: To determine if intolerance of uncertainty, depression, anxiety, worry, or stress are related to post-op regret in otolaryngology patients. METHODS: Adult patients or parents giving consent for pediatric patients meeting criteria for otolaryngologic surgery were recruited and completed the Intolerance of Uncertainty Scale (IUS-12), Penn State Worry Questionnaire (PSWQ), and Depression, Anxiety and Stress Scale-21 (DASS-21) preop and the Decisional Regret (DR) scale 1-month post-op. Pearson correlations were calculated. RESULTS: The cohort included 109 patients, 73 (67%) males and 36 (33.3%) females. 43 (39.5%) were college graduates and 66 (60.9%) were not. Mean IUS-12 score was 22.9 (95% CI 21.0-24.8), mean PSWQ score was 46.9 (95% CI 44.5-49.3). DASS-21 mean score was 11.9 (95% CI 9.6-14.3). Mean DR score was 11.1 (95% CI 8.6-13.6). IUS-12 subscales Prospective Anxiety mean score was 14.2 (95% CI 12.8-15.5) and Inhibitory Anxiety mean score was 16.5 (95% CI 14.5-18.6). The Pearson correlation coefficient for post-op DR and total preop IUS was .188 (P = .027) and the correlation coefficient for post-op DR and preop Prospective Anxiety subscale of IUS score was .174 (P = .037). Correlations with PSWQ and DASS-21 scores and DR were not statistically significant. CONCLUSION: Intolerance of uncertainty is a psychological construct that is associated with post-op DR. More work is needed to determine whether screening for IU and behavior modification directed at IU for those with high levels would improve post-op decisional regret.

Test-retest reliability of human threat conditioning and generalization across a 1-to-2-week interval.

Given the increasing use of threat conditioning and generalization for clinical-translational research efforts, establishing test-retest reliability of these paradigms is necessary. Specifically, it is an empirical question whether the same participant evinces a similar generalization gradient of conditioned responses across two sessions with the identical contingencies and stimuli. Here, 46 human volunteers participated in an identical auditory threat acquisition and generalization protocol at two sessions separated by 1-to-2 weeks. Skin conductance responses (SCR) and trial-by-trial shock risk ratings served as primary measures. We used linear mixed effects modeling to test differential threat responses and generalization gradients, and Generalizability (G) theory coefficients as our primary formal assessment of test-retest reliability of intraindividual stability and change across time. Results showed largely invariant differential conditioning and generalization gradients across time. G coefficients indicated fair reliability for acquisition and generalization SCR. In contrast, risk rating reliabilities were mixed, and reliability was particularly low for acquisition risk ratings. Our findings generally support reliability of the threat conditioning and generalization paradigm for shorter test-retest intervals and highlight their utility for assessments of behavioral interventions in mental health research, but challenges remain and further work is needed. Threat conditioning and generalization tasks are increasingly used for translational efforts to improve behavioral interventions, and thus test-retest reliability for these tasks needs to be established. Our results support the test-retest reliability of threat conditioning and generalization over a relatively short (1-to-2 week) interval, but this depends on the measure used (physiological vs. self-report). Overall, these tasks could be appropriate for repeated testing over the course of a short-duration intervention study, but more research is needed, particularly in regard to longer-duration studies.

Addressing Uncertainty in Informal Familial Caregivers of Stroke Survivors: A Systematic Meta-Ethnography.

Background: Informal familial caregivers of stroke survivors experience uncertainty that begins at the time of the stroke event and continues into home-based care. The uncertainty faced by caregivers contributes to poor mental and physical health outcomes. Objective: This review details the factors associated with, impacts of, and coping skills used to manage uncertainty across the caregiving trajectory. By defining uncertainty reduction and tolerance recommendations, this review also builds upon the Stroke Caregiver Readiness Model to improve preparedness following the stroke event. Methods: A meta-ethnographic review was systematically conducted on thirteen qualitative studies with 218 participants from four countries. The Critical Appraisal Skills Programme (CASP) was used to assess study quality. Results: Following the stroke event, caregivers reported a lack of knowing (e.g., about the cause of the stroke event and survivor prognoses) as contributing to post-stroke uncertainty. As a result of this uncertainty, caregivers expressed concerns about their abilities to navigate caregiving responsibilities and how to plan for the future. Longer-term concerns (e.g., managing finances) and feelings of hopelessness occurred after discharge. Still, caregivers identified strategies to manage uncertainty. Caregiver coping skills included present-focused thinking, gratitude, faith, humor, and social support. Conclusions: The uncertainty faced by informal familial caregivers of stroke survivors is pervasive and changes across time. Uncertainty reduction and tolerance interventions can be used to build upon caregiver strengths and promote preparedness across the caregiving trajectory.

A Preliminary Test of Novelty-Facilitated Extinction in Individuals With Pathological Anxiety.

Studies with rodents and healthy humans suggest that replacing the expected threat with a novel outcome improves extinction and reduces the return of conditioned fear more effectively than threat omission alone. Because of the potential clinical implications of this finding for exposure-based anxiety treatments, this study tested whether the same was true in individuals with pathological anxiety (i.e., met DSM-5 diagnostic criteria for an anxiety disorder and/or obsessive-compulsive disorder (OCD). In this preliminary test of novelty-facilitated extinction, 51 unmedicated individuals with pathological anxiety were randomized to standard extinction (n = 27) or novelty-facilitated extinction (n = 24). Participants returned 24 h later to test extinction recall and fear reinstatement. Skin conductance responses (SCR) were the dependent measure of conditioned fear. Participants in both groups learned the fear association but variably extinguished it. Novelty did not facilitate extinction in this preliminary trial. Findings underscore the importance of translating paradigms from healthy humans to clinical samples, to ensure that new treatment ideas based on advances in basic neuroscience are relevant to patients.

Maintenance of Wellness in Patients With Obsessive-Compulsive Disorder Who Discontinue Medication After Exposure/Response Prevention Augmentation: A Randomized Clinical Trial.

IMPORTANCE: Serotonin reuptake inhibitors (SRIs) are the only medications approved for obsessive-compulsive disorder (OCD), yet most patients taking SRIs exhibit significant symptoms. Adding exposure/response prevention (EX/RP) therapy improves symptoms, but it is unknown whether patients maintain wellness after discontinuing SRIs. OBJECTIVE: To assess whether patients with OCD who are taking SRIs and have attained wellness after EX/RP augmentation can discontinue their SRI with noninferior outcomes compared with those who continue their SRI therapy. DESIGN, SETTING, AND PARTICIPANTS: A 24-week, double-blind, randomized clinical trial was performed from May 3, 2013, to June 25, 2018. The trial took place at US academic medical centers. Participants included 137 adults with a principal diagnosis of OCD (≥1 year) who were taking an SRI (≥12 weeks), had at least moderate symptoms (defined as Yale-Brown Obsessive-Compulsive Scale [Y-BOCS] score ≥18 points), and received as many as 25 sessions of EX/RP therapy. Those who attained wellness (Y-BOCS score ≤14 points; 103 patients [75.2%]) were study eligible. Data were analyzed from June 29, 2019, to October 2, 2021. INTERVENTION: Participants were randomly assigned either to receive taper to placebo (taper group) or to continue their SRI (continuation group) and monitored for 24 weeks. MAIN OUTCOME AND MEASURES: The Y-BOCS score (range, 0-40 points) was the primary outcome; the Hamilton Depression Rating Scale (HDRS; range, 0-52 points) and the Quality-of-Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF; range, 0%-100%) scores were secondary outcomes. Outcomes were assessed at 8 time points by independent evaluators who were blinded to randomization. The taper regimen was hypothesized to be noninferior to continuation at 24 weeks using a 1-sided α value of .05. RESULTS: A total of 101 patients (mean [SD] age, 31.0 [11.2] years; 55 women [54.5%]) participated in the trial: 51 patients (50.5%) in the taper group and 50 patients (49.5%) in the continuation group. At 24 weeks, patients in the taper group had noninferior results compared with patients in the continuation group (mean [SD] Y-BOCS score: taper group, 11.47 [6.56] points; continuation group: 11.51 [5.97] points; difference, -0.04 points; 1-sided 95% CI, -∞ to 2.09 points [below the noninferiority margin of 3.0 points]; mean [SD] HDRS score: taper group, 5.69 [3.84] points; continuation group, 4.61 [3.46] points; difference, 1.08 points; 1-sided 95% CI, -∞ to 2.28 points [below the noninferiority margin of 2.5 points]; mean [SD] Q-LES-Q-SF score: taper group, 68.01% [15.28%]; continuation group, 70.01% [15.59%]; difference, 2.00%; 1-sided 95% CI, -∞ to 6.83 [below the noninferiority margin of 7.75]). However, the taper group had higher rates of clinical worsening (23 of 51 [45%] vs 12 of 50 [24%]; P = .04). CONCLUSIONS AND RELEVANCE: Results of this randomized clinical trial show that patients with OCD who achieve wellness after EX/RP therapy could, on average, discontinue their SRI with noninferior outcomes compared with those who continued their SRI. Those who tapered the SRI had higher clinical worsening rates. Future research should evaluate if SRI half-life alters these rates. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01686087.

Feasibility and Acceptability of Guided Imagery to Sequentially Address Multiple Health Behaviors During Pregnancy.

INTRODUCTION: Pregnancy presents health challenges related to well-being, physical activity, dietary regulation, and body image. There is evidence to support the use of guided imagery to address these concerns during pregnancy. The purpose of this study was to analyze the use and short-term outcomes of a multiple-behavior guided imagery intervention delivered through a mobile health (mHealth) application for pregnant women. METHODS: A single-arm, 5-week feasibility trial was conducted, and participants were instructed to listen to an audio file every day for 35 days on an mHealth application. Measurements included ongoing assessments of the participants' use of the guided imagery audio files and pre- and post-test measures of depression, anxiety, stress, physical activity, food cravings, and body image. Postintervention qualitative interviews were conducted to assess whether participants would continue to use guided imagery. RESULTS: Fifty-eight participants (mean age, 28.5 years) were enrolled from January to June of 2018. Cloud analytics data showed an average of 4.96 audio downloads per week with the Sleep and Relaxation file being the most widely used (mean weekly usage, 5.67) and reported favorite during follow-up interviews. Paired-sample t tests from pre- to post-test showed significant reductions in depression, anxiety, and stress, increased physical activity, and sedentary behavior along with some changes in body image. DISCUSSION: Future scalable guided imagery interventions are justified to test for efficacy. Guided imagery may also be delivered in person by health care providers or by using widely available technologies.

Which variations of a brief cognitive bias modification session for interpretations lead to the strongest effects?

BACKGROUND: Brief computerized programs that train less threatening interpretations (termed Cognitive Bias Modification for Interpretations, or CBM-I) can shift interpretation biases and subsequent anxiety symptoms. However, results have been inconsistent, particularly for studies conducted over the Internet. METHODS: The current exploratory study tests 13 variations of a single brief session of CBM-I, a non-CBM-I cognitive flexibility condition, a neutral condition, and a no task control condition in an analogue sample with moderate to severe anxiety. RESULTS: Results suggest that all conditions, except the neutral scenarios condition and the alternative way to improve cognitive flexibility, led to changes in interpretations (when compared to the no task control condition). Only conditions geared toward increasing imagery during CBM-I and targeting flexibility related to emotional material differed from the no task control condition on other post-training measures. CONCLUSIONS: Presenting valenced interpretations of ambiguous information during brief CBM-I, regardless of the format, can lead to changes in interpretation bias. However, most conditions did not differ from the no task control condition on other post-training assessments (and differences that did occur may be due to chance). Future trials should consider further testing of CBM-I that targets flexibility related to emotional material, and should include an increased number of sessions and trials.

The Role of Emotional Distress Tolerance on Fear Responding in a Heights-Fearful Sample: Perceived Versus Actual Behavior.

Emotional distress tolerance (EDT)-or the ability to withstand negative emotional states-is considered a transdiagnostic risk factor for psychopathology. Although EDT is theorized to play a role in anxiety development and maintenance, research aiming to delineate the relationship between anxiety and EDT is lacking. The current study tested whether self-reported EDT predicted self-reported and actual avoidance in the presence of feared stimuli using a heights-fearful sample. Moreover, the study tested whether EDT predicted other in-the-moment fear responses, such as peak anxiety, anxious cognitions, and bodily sensations. Participants (N = 128) completed questionnaires assessing fear of heights, negative affect, anxious cognitions, and bodily sensations, as well as two heights behavioral avoidance tasks (BATs). Results demonstrated that EDT did not predict actual avoidance or other in-the-moment fear responses, except for peak anxiety in one BAT. However, EDT predicted self-reported avoidance of heights beyond fear of heights and negative affect. Taken together, results suggest that perception of ability to tolerate emotional distress predicts perception of avoidance of heights, but not actual avoidance of heights or reactions to heights (with the exception of peak anxiety in one BAT). Given these findings, self-reported EDT may not adequately predict how individuals react in anxiety-provoking situations.

Maximizing remission from cognitive-behavioral therapy in medicated adults with obsessive-compulsive disorder.

Practice guidelines for adults with obsessive-compulsive disorder (OCD) recommend augmenting serotonin reuptake inhibitors (SRIs) with exposure and ritual prevention (EX/RP). However, fewer than half of patients remit after a standard 17-session EX/RP course. We studied whether extending the course increased overall remission rates and which patient factors predicted remission. Participants were 137 adults with clinically significant OCD (Yale-Brown Obsessive Compulsive Scale [Y-BOCS] score ≥18) despite an adequate SRI trial (≥12 weeks). Continuing their SRI, patients received 17 sessions of twice-weekly EX/RP (standard course). Patients who did not remit (Y-BOCS ≤12) received up to 8 additional sessions (extended course). Of 137 entrants, 123 completed treatment: 49 (35.8%) remitted with the standard course and another 46 (33.6%) with the extended course. Poorer patient homework adherence, more Obsessive-Compulsive Personality Disorder (OCPD) traits, and the Brain-Derived Neurotrophic Factor (BDNF) Val66MET genotype were associated with lower odds of standard course remission. Only homework adherence differentiated non-remitters from extended course remitters. Extending the EX/RP course from 17 to 25 sessions enabled many (69.3%) OCD patients on SRIs to achieve remission. Although behavioral (patient homework adherence), psychological (OCPD traits), and biological (BDNF genotype) factors influenced odds of EX/RP remission, homework adherence was the most potent patient factor overall.

Women's Knowledge of Postpartum Anxiety Disorders, Depression, and Cognitive Behavioral Therapy.

ABSTRACT: Although awareness of postpartum depression (PPD) has increased, postpartum anxiety disorders (PPA) remain overlooked. Understanding women's knowledge of PPA and their effective treatments is needed given the underutilization of treatment and associated negative health outcomes. Two internet-based studies (OSF [https://osf.io/3fjvr] preregistered follow-up) were conducted to identify women's knowledge and familiarity with PPD and PPA and knowledge of cognitive behavioral therapy (CBT). Study 1 revealed that women who were planning to become pregnant, pregnant, or recently postpartum (N = 218) were less familiar with PPA than PPD and had limited familiarity with CBT. Women also reported low screening rates for PPA and low perceived treatment seeking for women with PPA and PPD. Study 2 (N = 290) revealed that recently postpartum women recognized fewer symptoms and recommended treatment less often for PPA than PPD and had limited CBT knowledge. Overall, results indicate limited knowledge of PPA compared with PPD, indicating a need for targeted information to perinatal women.

Relationship Between Parental Intolerance of Uncertainty and Decisional Conflict in Pediatric Otolaryngologic Surgery.

OBJECTIVE: To assess the relationship between depression, anxiety, stress, worry, intolerance of uncertainty (IU), and shared decision making (SDM) in parents of pediatric otolaryngology surgical patients with their perceptions of decisional conflict (DC). STUDY DESIGN: Cross-sectional. SETTING: Academic pediatric otolaryngology outpatient clinic. METHODS: Participants were legal guardians of pediatric patients who met criteria for otolaryngologic surgery. Participants completed a demographic survey as well as validated Decisional Conflict Scale (DCS); Shared Decision-Making Scale (SDMS); Depression, Anxiety and Stress Scale-21 (DASS-21); Penn State Worry Questionnaire (PSWQ); and short form of the Intolerance of Uncertainty Scale (IUS-12). RESULTS: A total of 114 participants were enrolled. Respondents were predominantly female (93.0%) and married (60.5%). Most guardians had not consented previously for otolaryngologic surgery for their child (69.3%). Participants reported low levels of DC and depression as well as moderate levels of anxiety and stress. DC scores were not significantly correlated to DASS-21, PSWQ, or SDM. IUS-12 Total and subscale IUS-12 prospective negatively correlated with Total DC. DC was not related to age, sex, education level, previous otolaryngologic surgery, or type of surgery recommended. CONCLUSION: In this group, an association was found between IU and DC. Clinicians should be aware that DC is not modified by previous surgical experience. Interventions aimed at addressing parental IU related to surgery may reduce DC. Further research efforts could help us understand how mental health relates to surgical decision making.

Mnemonic discrimination and social anxiety: the role of state anxiety.

The Mnemonic Similarity Task (MST) measures mnemonic discrimination, or the ability to correctly identify new stimuli from highly similar, old stimuli. Poor mnemonic discrimination is a potential risk or maintenance factor for anxiety, and recent studies suggest state affect may moderate relations between mnemonic discrimination and trait anxiety. No studies have evaluated mnemonic discrimination in specific subtypes of anxiety or with clinically relevant stressors. This preregistered study evaluated the role of social anxiety and the anticipation of a future speech on MST performance. Participants with high (n = 66) and low (n = 64) levels of social anxiety were randomly assigned to a stressor condition or a control condition prior to the MST. State anxiety was measured throughout the study. Results did not indicate significant effects of trait (high vs. low social anxiety) or state anxiety (stressor condition vs. control condition) on mnemonic discrimination. Results are compared with previous research and implications and future directions are discussed.

Threat and benign interpretation bias might not be a unidimensional construct.

The tendency for individuals to interpret ambiguous information in a threatening way is theorised to maintain anxiety disorders. Recent findings suggest that positive and negative interpretation biases may have unique effects. This study tested the relationships between threat and benign biases with state and trait anxiety and quality of life, and whether individual differences moderate these relationships. N = 699 individuals with elevated trait anxiety symptoms completed web-based measures of interpretation bias, trait anxiety, state anxiety, and quality of life. Results demonstrated that threat interpretations predicted state anxiety, trait anxiety, and quality of life. Benign interpretations also predicted quality of life. However, benign interpretations only weakly (or not at all) predicted state and trait anxiety. Individual differences (e.g. gender, race, ethnicity, age) did not moderate findings. Results emphasise the need to consider benign and threat biases separately, both in cognitive models of anxiety and experimental designs.

A Framework for Understanding the Role of Psychological Processes in Disease Development, Maintenance, and Treatment: The 3P-Disease Model.

Health psychology is multidisciplinary, with researchers, practitioners, and policy makers finding themselves needing at least some level of competency in a variety of areas from psychology to physiology, public health, and others. Given this multidisciplinary ontology, prior attempts have been made to establish a framework for understanding the role of biological, psychological, and socio-environmental constructs in disease development, maintenance, and treatment. Other models, however, do not explain how factors may interact and develop over time. The aim here was to apply and adapt the 3P model, originally developed and used in the treatment of insomnia, to couch the biopsychosocial model in a way that explains how diseases develop, are maintained, and can be treated. This paper outlines the role of predisposing, precipitating, and perpetuating factors in disease states and conditions (the 3Ps) and provides examples of how this model may be adapted and applied to a number of health-related diseases or disorders including chronic pain, gastrointestinal disorders, oral disease, and heart disease. The 3P framework can aid in facilitating a multidisciplinary, theoretical approach and way of conceptualizing the study and treatment of diseases in the future.

Believing is seeing: Changes in visual perception following treatment for height fear.

BACKGROUND AND OBJECTIVES: People who are afraid of heights may have a perceptual bias, such that they see heights as higher than they truly are. The current study tested if there is a causal relationship between treatments for height fear and changes in perceptual bias. METHODS: Specifically, the effects on perceptual bias following three height fear interventions (exposure, cognitive bias modification for interpretations, and a combination of exposure and cognitive bias modification) and a control condition were examined in individuals with an extreme fear of heights (N = 107). RESULTS: Results provided preliminary evidence that some height fear interventions reduce perceptual bias. Specifically, participants that completed exposure had a significant decrease in perceptual bias, and participants in the cognitive bias modification and combination conditions had decreases in perceptual bias at the level of non-significant trends, while no reduction occurred for the control condition. LIMITATIONS: Limitations of this study include that the hypothesis was largely informed by data from a parent study and that the effect sizes were small; thus, replicating these results is warranted. CONCLUSIONS: These findings suggest that there may be a causal relationship between height fear treatments and altered perception of heights.

Psychometric Properties of the Difficulties in Emotion Regulation Scale (DERS) and Its Short Forms in Adults With Emotional Disorders.

Objective: The Difficulties in Emotion Regulation Scale (DERS) is a widely used self-report measure of subjective emotion ability, as defined by a prominent clinically derived model of emotion regulation (Gratz and Roemer, 2004). Although the DERS is often used in treatment and research settings for adults with emotional (i.e., anxiety, mood, obsessive-compulsive, or trauma-related) disorders, its psychometric properties are not well-characterized in this population. Method: We examined the psychometric properties of the DERS and three popular short forms (DERS-16; DERS-18; and DERS-SF) in a large (N = 427) sample of treatment-seeking adults with one or more DSM-5 emotional disorders. Results: For the original DERS, internal consistency was strong for all subscales except Awareness. A bifactor structure consisting of one general emotion dysregulation factor and five uncorrelated specific factors corresponding to the original DERS subscales (excluding Awareness) provided the best fit. A series of structural equation models (SEMs) demonstrated unique incremental contributions of the general factor and several specific factors to explaining concurrent clinical severity. The general factor and one specific factor (Goals) also prospectively predicted treatment outcome following a naturalistic course of outpatient cognitive-behavioral therapy (CBT) in a subset of participants (n = 202) for whom discharge data were available. Specifically, more severe emotion dysregulation at intake predicted better CBT response, while more severe impairment in goal-directed activity when distressed predicted worse CBT response. All three short forms showed a robust bifactor structure and good internal consistency and convergent validity vis-à-vis the original measure, albeit with a slight decrement in incremental utility (1-3% less variance explained in clinical severity). Conclusion: With the Awareness items excluded, the DERS showed good internal consistency and a robust bifactor latent structure. The general factor and several specific factors incrementally and prospectively predicted clinical severity and treatment outcome, which suggests that the DERS may have clinical and predictive utility in treatment-seeking adults with emotional disorders. Additional research is needed to establish convergent and discriminant validity in this population. The use of a short form in lieu of the full DERS may be sufficient for many general clinical and research purposes, particularly when participant burden is a concern.
