Competing Models of Personality Disorder: Relations With Psychosocial Functioning.

The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5; American Psychiatric Association, 2013), includes 10 categorical personality disorders (PD) in Section II (Section II PD) and a dimensional alternative model of PD (AMPD) in Section III. We compared the two models in explaining concurrent psychosocial functioning levels in psychiatric outpatients and community residents screened as at risk for PD pathology (N = 600). The AMPD's fully dimensional form showed stronger associations with psychosocial difficulties and explained more of their variance compared with the categorical Section II PD. AMPD Criterion A (personality functioning impairment) and Criterion B (pathological traits) incrementally predicted psychosocial functioning about equally with some unique predictions. Finally, AMPD's six categorical PD diagnoses did not show stronger associations with psychosocial functioning than the corresponding Section II PD diagnoses. Findings directly comparing the two models remain important and timely for informing future conceptualizations of PD in the diagnostic system.

Meta-Analytic Review of Temperamental Correlates of the Five-Factor Model and Hierarchical Taxonomy of Psychopathology Domains.

Background: There is little and heterogeneous knowledge on the links between the temperamental predispositions of psychopathology and the contemporary dimensional models of psychopathology, such as the Hierarchical Taxonomy of Psychopathology (HiTOP) classification system, which can be aligned with the five-factor model (FFM) of personality. This meta-analysis seeks to expand the temperamental theoretical basis of the HiTOP model by incorporating associations of temperament traits of two temperamental theories measured, respectively, by the Temperament and Character Inventory (TCI) and the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) with (a) the FFM's personality domains and (b) HiTOP's five psychopathological spectra. Methods: A systematic search was done on Web of Science, Scopus, PubMed, ProQuest, Cochrane Database, and Google Scholar for all articles published in English from January 1990 to August 2020. Because of heterogeneity in the results of almost 70% of studies, pooled estimates of correlation coefficients were calculated using the random-effects method. Risk of bias (low-quality studies) and publication bias are reported. Results: The pooled correlations obtained from the analysis of 35 studies showed that the temperamental profile associated with each FFM domain and HiTOP spectra is distinct. Specifically, TCI-harm avoidance (HA) and all TEMPS temperaments were more strongly related to neuroticism/internalizing, extraversion/low detachment, and conscientiousness/disinhibition. In contrast, TCI-novelty seeking was more strongly related to both disinhibited/antagonistic externalizing and thought disorder. Conclusions: A large body of research supports maladaptive variants of all FFM domains and some psychopathological spectra of HiTOP related to the abnormal-range temperaments.

Personality disorder coverage, prevalence, and convergence: do the DSM-5's two models of personality disorder identify the same patients?

BACKGROUND: Research on the Alternative DSM-5 Model for Personality Disorders (AMPD) in DSM-5's Section-III has demonstrated acceptable interrater reliability, a largely consistent latent structure, substantial correlations with theoretically and clinically relevant measures, and evidence for incremental concurrent and predictive validity after controlling for DSM-5's Section II categorical personality disorders (PDs). However, the AMPD is not yet widely used clinically. One clinician concern may be caseness - that the new model will diagnose a different set of PD patients from that with which they are familiar. The primary aim of this study is to determine whether this concern is valid, by testing how well the two models converge in terms of prevalence and coverage. METHOD: Participants were 305 psychiatric outpatients and 302 community residents not currently in mental-health treatment who scored above threshold on the Iowa Personality Disorder Screen (Langbehn et al., ). Participants were administered a semi-structured interview for DSM-5 PD, which was scored for both Section II and III PDs. RESULTS: Convergence across the two PD models was variable for specific PDs, Good when specific PDs were aggregated, and Very Good for 'any PD.' CONCLUSIONS: Results provide strong evidence that the AMPD yields the same overall prevalence of PD as the current model and, further, identifies largely the same overall population. It also addresses well-known problems of the current model, is more consistent with the ICD-11 PD model, and provides more complete, individualized characterizations of persons with PD, thereby offering multiple reasons for its implementation in clinical settings.

Associations of antidepressant medication consumption with changes in personality pathology and quality of life among community-dwelling adults.

BACKGROUND: Although antidepressant medication (ADM) has produced small advantages over pill placebo in randomized controlled trials, consuming ADM has predicted prospectively increasing depressive symptom severity in samples of community-dwelling adults. OBJECTIVE: We extended the community literature by testing ADM's relations to changes in personality and quality of life that may underpin depression. METHOD: In this longitudinal, observational study, community-dwelling adults (N = 601) were assessed twice, 8 months apart on average. Assessments included depressive symptoms, personality, life satisfaction and quality, and prescription medication consumption. RESULTS: Consuming ADM at time 1 predicted relative increases in depressive symptoms (dysphoria), maladaptive traits (negative affect, negative temperament, disinhibition, low conscientiousness), personality dysfunction (non-coping, self-pathology), and decreases in life satisfaction and quality from time 1 to 2, before and after adjustment for age, gender, race, income, education, physical health problems, and use of other psychotropics. In no analysis did ADM use predict better outcomes. CONCLUSION: Among community-dwelling adults, ADM use is a risk factor for psychosocial deterioration in domains including depressive symptoms, personality pathology, and quality of life. Until mechanisms connecting ADM to poor outcomes in community samples are understood, additional caution in use of ADM and consideration of empirically supported non-pharmacologic treatments is prudent.

Longitudinal and Concurrent Effortful Control as Predictors of Risky Bicycling in Adolescence: Moderating Effects of Age and Gender.

OBJECTIVE: Collisions between bicycles and motor vehicles are one of the leading risk factors for injury and death in childhood and adolescence. We examined longitudinal and concurrent effortful control (EC) as predictors of risky bicycling behavior in early- to mid-adolescence, with age and gender as moderators. We also examined whether EC was associated with parent-reported real-world bicycling behavior and all lifetime unintentional injuries. METHODS: Parent-reported EC measures were collected when children (N = 85) were 4 years old and when they were either 10 years (N = 42) or 15 years (N = 43) old. We assessed risky bicycling behavior by asking the adolescents to bicycle across roads with high-density traffic in an immersive virtual environment. Parents also reported on children's real-world bicycling behavior and lifetime unintentional injuries at the time of the bicycling session. RESULTS: We found that both longitudinal and concurrent EC predicted adolescents' gap choices, though these effects were moderated by age and gender. Lower parent-reported early EC in younger and older girls predicted a greater willingness to take tight gaps (3.5 s). Lower parent-reported concurrent EC in older boys predicted a greater willingness to take gaps of any size. Children lower in early EC started bicycling earlier and were rated as less cautious bicyclists as adolescents. Adolescents lower in concurrent EC were also rated as less cautious bicyclists and had experienced more lifetime unintentional injuries requiring medical attention. CONCLUSION: Early measures of child temperament may help to identify at-risk populations who may benefit from parent-based interventions.

Principles and procedures for revising the hierarchical taxonomy of psychopathology.

Quantitative, empirical approaches to establishing the structure of psychopathology hold promise to improve on traditional psychiatric classification systems. The Hierarchical Taxonomy of Psychopathology (HiTOP) is a framework that summarizes the substantial and growing body of quantitative evidence on the structure of psychopathology. To achieve its aims, HiTOP must incorporate emerging research in a systematic, ongoing fashion. In this article, we describe the historical context and grounding of the principles and procedures for revising the HiTOP framework. Informed by strengths and shortcomings of previous classification systems, the proposed revisions protocol is a formalized system focused around three pillars: (a) prioritizing systematic evaluation of quantitative evidence by a set of transparent criteria and processes, (b) balancing stability with flexibility, and (c) promoting inclusion over gatekeeping in all aspects of the process. We detail how the revisions protocol will be applied in practice, including the scientific and administrative aspects of the process. Additionally, we describe areas of the HiTOP structure that will be a focus of early revisions and outline challenges for the revisions protocol moving forward. The proposed revisions protocol is designed to ensure that the HiTOP framework reflects the current state of scientific knowledge on the structure of psychopathology and fulfils its potential to advance clinical research and practice.

Disinhibition domain and facets uniquely predict changes in depressive symptoms and psychosocial functioning.

This study aimed to understand the role of disinhibition (low conscientiousness)-in conjunction with the other major personality traits of negative affectivity, detachment, antagonism, and psychoticism-in predicting changes in depressive symptoms and psychosocial functioning. Both the disinhibition trait domain and its primary facets (i.e., irresponsibility, impulsivity, and distractibility) were examined. In a large sample (Time 1 N = 605, Time 2 N = 497) of psychiatric outpatients and high-risk community residents, personality traits, depressive symptoms (both self-reported and interviewer-rated), and psychosocial functioning levels (i.e., daily functioning, interpersonal functioning, health-related quality of life, and global quality of life) were collected across two time points. Results showed that the disinhibition domain was the strongest predictor of changes in depressive symptoms and general quality of life levels. Disinhibition facets also predicted changes in depressive symptoms but showed a less consistent pattern compared to the broader trait domain. Finally, the irresponsibility and distractibility facets significantly and uniquely explained changes in interpersonal functioning. The study highlights the importance of assessing the disinhibition trait rather than only negative and positive affectivity (which are well-known correlates of depression), for understanding changes in depressive symptoms and psychosocial functioning. The findings identify potential targets in psychotherapy for individuals with disinhibition traits and depressive disorders.

The nature and neurobiology of fear and anxiety: State of the science and opportunities for accelerating discovery.

Fear and anxiety play a central role in mammalian life, and there is considerable interest in clarifying their nature, identifying their biological underpinnings, and determining their consequences for health and disease. Here we provide a roundtable discussion on the nature and biological bases of fear- and anxiety-related states, traits, and disorders. The discussants include scientists familiar with a wide variety of populations and a broad spectrum of techniques. The goal of the roundtable was to take stock of the state of the science and provide a roadmap to the next generation of fear and anxiety research. Much of the discussion centered on the key challenges facing the field, the most fruitful avenues for future research, and emerging opportunities for accelerating discovery, with implications for scientists, funders, and other stakeholders. Understanding fear and anxiety is a matter of practical importance. Anxiety disorders are a leading burden on public health and existing treatments are far from curative, underscoring the urgency of developing a deeper understanding of the factors governing threat-related emotions.

Evaluating a Comprehensive Model of Euthymia.

INTRODUCTION: In research and treatment of mood disorders, "euthymia" traditionally denotes the absence of clinically significant mood disturbance. A newer, expanded definition of euthymia also includes positive affect and psychological well-being. OBJECTIVE: We aimed to test this comprehensive model of euthymia and estimate the coherence and predictive power of each factor in the model. METHODS: Community-dwelling adults (N = 601), including both mental health outpatients and non-patients at high risk for personality pathology, completed a battery of interviews and questionnaires at time 1. Most (n = 497) were reassessed on average 8 months later (time 2). We modeled euthymia using standard mood, personality, and psychosocial functioning assessments rather than measures designed specifically for euthymia. RESULTS: The hypothesized model of euthymia was supported by confirmatory factor analysis: specific measures loaded on three lower order factors (mood disturbance, positive affect, and psychological well-being) that reflected general euthymia at time 1. Each factor (general euthymia plus lower order factors) demonstrated moderately strong concurrent (time 1) and predictive (time 1-2) correlations with outcomes, including employment status, income, mental health treatment consumption, and disability. Compared to positive affect and psychological well-being, mood disturbance had stronger incremental (i.e., nonoverlapping) relations with these outcomes. CONCLUSIONS: Support for a comprehensive model of euthymia reinforces efforts to improve assessment and treatment of mood and other disorders. Beyond dampening of psychological distress, euthymia-informed treatment goals encompass full recovery, including enjoyment and meaning in life.

Young Adult Mental Health Beyond the COVID-19 Era: Can Enlightened Policy Promote Long-Term Change?

The status of mental health for adolescents and young adults has aptly been termed a "crisis" across research, clinical, and policy quarters. Arguably, the status quo provision of mental health services for adolescents and young adults is neither acceptable nor salvageable in its current form. Instead, only a wholesale policy transformation of mental health sciences can address crises of this scope. Pandemic-related impacts on mental health, particularly among young adults, have clearly exposed the need for the mental healthcare field to develop a set of transformative priorities to achieve long overdue, systemic changes: (1) frequent mental health tracking, (2) increased access to mental health care, (3) working with and within communities, (4) collaboration across disciplines and stakeholders, (5) prevention-focused emphasis, (6) use of dimensional descriptions over categorical pronouncements, and (7) addressing systemic inequities. The pandemic required changes in mental healthcare that can and should be the beginning of long-needed reform, calling upon all mental health care disciplines to embrace innovation and relinquish outdated traditions.

Comorbidity and heterogeneity: Two challenges for personality pathology research.

We critique the general state of methodological rigor in contemporary personality pathology research, focusing on challenges in study design, assessment, and data analysis resulting from two pervasive problems: comorbidity and heterogeneity. To inform our understanding of this literature, we examined every article published in the two main specialty journals for personality pathology research-Personality Disorders: Theory, Research, and Treatment and the Journal of Personality Disorders-in the 18-month period from January 2020 to June 2021 (a total of 23 issues and 197 articles). Our review of this database indicated that only three forms of personality pathology have generated substantial attention in the recent literature: borderline personality disorder (featured in 93 articles), psychopathy/antisocial personality disorder (39 articles), and narcissism/narcissistic personality disorder (28 articles), so we highlight them in our review. We discuss comorbidity-related problems that arise from group-based designs and recommend instead that researchers assess multiple forms of psychopathology as continuous dimensions. We offer separate recommendations for addressing heterogeneity in diagnosis- versus trait-based studies. For the former, we recommend that researchers (a) use measures that permit criterion-level analyses and (b) routinely report criterion-level results. For the latter, we emphasize the importance of examining specific traits when measures are known to be highly heterogeneous/multidimensional. Finally, we encourage researchers to work toward a truly comprehensive trait dimensional model of personality pathology. We suggest that this might include expanding the current alternative model of personality disorders to include additional content related to borderline features, psychopathy, and narcissism.

Structure of Pathological Personality Traits Through the Lens of the CAT-PD Model.

Personality pathology is increasingly conceptualized within hierarchical, dimensional trait models. The Comprehensive Assessment of Traits Relevant to Personality Disorders (CAT-PD) is a pathological-trait measure with potential to improve on currently prevailing instruments because it has wider content coverage; however, its domain-level structure, which is of scientific and clinical interest, is not established. In this study, we investigated the structure and construct validity of the CAT-PD's domain level to facilitate wider use of the measure. We estimated five- and six-factor models with exploratory factor analysis in a pooled sample of eight independent subsamples (N = 3,987) and found that both models fit the data well; each had interpretable factors that were invariant across gender, sample type, and Black/White racial groups; and the factors had good convergent validity with other measures of maladaptive traits, Big Five personality, and interpersonal problems. Our results support the validity of the CAT-PD for assessing multiple levels of the pathological trait hierarchy.

The Predictive Validity of Consensual and Unique Facets of Neuroticism, Conscientiousness, and Agreeableness in Five Personality Inventories.

Consensual facet structures help to unify a highly fractured personality literature, but mask information obtained from unique personality facets assessed by individual personality inventories. The current study identifies the consensual and unique facets of neuroticism, conscientiousness, and agreeableness based on analyses of five widely used personality inventories (Disinhibition Inventory-I [DIS-I], Faceted Inventory for the Five-Factor model [FI-FFM], HEXACO Personality Inventory-Revised [HEXACO-PI-R], NEO Personality Inventory-3 [NEO-PI-3], and Temperament and Affectivity Inventory [TAI]) in a community sample (N = 440). Factor analyses revealed that neuroticism consisted of three consensual facets (distress/depression, anger, and sentimental anxiety) and four unique facets (shyness, regret/self-doubt, lassitude, and distractibility); conscientiousness consisted solely of four consensual facets (achievement striving, order, attentiveness, and responsibility); and agreeableness consisted solely of four consensual facets (prosociality, anger, venturesomeness, and trust). Regression analyses indicated that unique neuroticism facets predicted significant incremental variance across a range of psychological disorders. These results have significant implications for how neuroticism, conscientiousness, and agreeableness should be modeled at the lower order level in psychopathology research.

How can the DSM-5 alternative model of personality disorders advance understanding of depression?

BACKGROUND: The DSM-5 introduced an alternative model of personality disorder (AMPD) that includes personality dysfunction plus maladaptive-range traits. This study clarifies relations of depression diagnoses and symptoms with AMPD personality pathology. METHOD: Two samples (Ns 402 and 601) of outpatients and community-dwelling adults completed four depression (criteria met for major depressive disorder and dysthymia; dysphoria and low well-being scales), ten trait (two scales for each of five domains-negative affectivity, detachment, disinhibition, antagonism, psychoticism), and eight dysfunction (four scales for each of two domains-self- and interpersonal pathology) measures. Diagnoses were made using a semi-structured interview; other measures were self-reports. We quantified cross-sectional relations between depression and personality pathology with correlation and multiple regression analyses. RESULTS: Collectively (median R2; ps < 0.0001), the trait (0.46) and dysfunction (0.50) scales predicted the depression measures strongly, with most predictive power shared (0.41) between traits and dysfunction. However, trait and dysfunction scales altogether predicted depression (median R2 = 0.54) more strongly than either domain alone, ps < 0.0001. Participants with depression diagnoses showed elevations on all nonadaptive trait and personality dysfunction measures, particularly negative temperament/affectivity and self-pathology measures. LIMITATIONS: Generalization of findings to other populations (e.g., adolescents), settings (e.g., primary care), and measures (e.g., traditional personality disorder diagnoses) is uncertain. Cross-sectional analyses did not test changes over time or establish causality. CONCLUSIONS: The AMPD is highly relevant to depression. Assessment of personality pathology, including both personality dysfunction and maladaptive-range traits, stands to advance understanding of depression in adults.

Classification and assessment of fear and anxiety in personality and psychopathology.

We examine fear and anxiety in the context of structural models of personality (the five-factor model, or FFM) and psychopathology (the Hierarchical Taxonomy of Psychopathology, or HiTOP); we also highlight important issues related to their assessment. Anxiety is a sustained, future-oriented response to potential threat. Trait measures of anxiety represent a core facet within the broader domain of neuroticism in the FFM. Anxiety-related symptoms are indicators of the distress subfactor within the internalizing spectrum in HiTOP. In contrast, fear is a brief, present-focused response to an acute threat. We distinguish between two ways of assessing individual differences in fear. The first type assesses phobic responses to specific stimuli. Phobia measures are moderately correlated with measures of neuroticism in the FFM and define the fear subfactor of internalizing in HiTOP. The second type assesses individual differences in harm avoidance versus risk taking. Measures of risk taking (i.e., low fear) are moderately related to disinhibition/low conscientiousness and antagonism/low agreeableness in the FFM and are indicators of the externalizing superspectrum in HiTOP.

Does Symptom Linkage Density Predict Outcomes in Cognitive Therapy for Recurrent Depression?

Background: Acute-phase cognitive therapy (CT) is an efficacious treatment for major depressive disorder (MDD), but how CT helps patients is incompletely understood. As a potential means to clarify CT mechanisms, we defined "symptom linkage density" (SLD) as a patient's mean time-lagged correlation among nine depressive symptoms across 13 weekly assessments. We hypothesized that patients with higher SLD during CT have better outcomes (treatment response, and fewer symptoms after response), and we explored whether SLD correlated with other possible CT processes (growth in social adjustment and CT skills). Method: Data were drawn from two clinical trials of CT for adult outpatients with recurrent MDD (primary sample n = 475, replication sample n = 146). In both samples, patients and clinicians completed measures of depressive symptoms and social adjustment repeatedly during CT. In the primary sample, patients and cognitive therapists rated patients' CT skills. After CT, responders were assessed for 32 (primary sample) or 24 (replication sample) additional months to measure long-term depression outcomes. Results: Higher SLD predicted increases in social adjustment (both samples) and CT skills (primary sample) during CT, CT response (both samples), and lower MDD severity for at least 2 years after CT response (both samples). Analyses controlled patient-level symptom means and variability to estimate SLD's incremental predictive validity. Conclusions: These novel findings from two independent samples with longitudinal follow-up require further replication and extension. SLD may reflect or facilitate generalization of CT skills, improvement in social functioning, or other processes responsible for CT's shorter and longer term benefits.

The trait model of the DSM-5 alternative model of personality disorder (AMPD): A structural review.

Publication of the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition (American Psychiatric Association, 2013), which included an alternative model of personality disorders (AMPD), was followed by an explosion of publications on the new model. The large majority of these publications focused on the AMPD's Criterion B, which consists of 25 trait facets arranged in 5 broad domains that bear strong similarity to the established five-factor model (FFM) of personality. The operationalization of AMPD traits that has received the most research attention is its self-report measure, the Personality Inventory for Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition (PID-5; Krueger et al., 2012). Much of this literature concerns its internal structure and relations with FFM measures. Many of these studies report that a number of the facets appear to be (a) interstitial (cross-loading on 2 or more factors), (b) placed in the wrong domain (i.e., considered by the AMPD to be a facet of a different domain from the one on which it typically loads), or (c) both. Clarifying the structural location of measures is fundamental in understanding their nomological net-and, thereby, the constructs they assess. Therefore, this review focuses on the PID-5 structure in the context of the broader domain of personality, especially the FFM, and primarily examines (1) which facets are interstitial and (2) the best domain(s) in which to place each facet. Also considered are important PD constructs-including multiple facets and one domain-that the AMPD does not include. The review ends with a set of recommendations for AMPD-5.1 and PID-5.1.

The distinction between symptoms and traits in the Hierarchical Taxonomy of Psychopathology (HiTOP).

The Hierarchical Taxonomy of Psychopathology (HiTOP) is an empirically and quantitatively derived dimensional classification system designed to describe the features of psychopathology and, ultimately, to replace categorical nosologies. Among the constructs that HiTOP organizes are "symptom components" and "maladaptive traits," but past HiTOP publications have not fully explicated the distinction between symptoms and traits. We propose working definitions of symptoms and traits and explore challenges, exceptions, and remaining questions. Specifically, we propose that the only systematic difference between symptoms and traits in HiTOP is one of time frame. Maladaptive traits are dispositional constructs that describe persistent tendencies to manifest features of psychopathology, whereas symptoms are features of psychopathology as they are manifest during any specific time period (from moments to days to months). This has the consequence that almost every HiTOP dimension, at any level of the hierarchy, can be assessed as either a trait or a symptom dimension, by adjusting the framing of the assessment. We discuss the implications of these definitions for causal models of the relations between symptoms and traits and for distinctions between psychopathology, normal personality variation, and dysfunction.

Stability and Change in Relations Between Personality Traits and the Interpersonal Problems Circumplex During Cognitive Therapy for Recurrent Depression.

Both personality impairment and maladaptive-range traits are necessary for diagnosis in the alternative model of personality disorder. We clarified personality impairment-trait connections using measures of the interpersonal problems circumplex and personality traits among adult outpatients (N = 351) with major depressive disorder receiving cognitive therapy (CT). The trait scales' circumplex projections were summarized by elevation (correlations with general interpersonal problems), amplitude (specific relations to the circumplex dimensions of dominance and affiliation), and angle (predominant orientation in the two-dimensional circumplex). Most trait scales showed hypothesized circumplex relations, including substantive elevation (e.g., negative temperament, mistrust), amplitude (e.g., aggression, detachment), and expected angles (e.g., positive temperament and manipulativeness oriented toward overly nurturant/intrusive or domineering/vindictive problems, respectively), that were stable across time during CT. These results revealed meaningful and consistent impairment-trait connections, even during CT when mean depressive affect decreased substantially.

Levels of depressed mood and low interest for two years after response to cognitive therapy for recurrent depression.

BACKGROUND: Major depressive disorder (MDD) involves depressed mood (high negative affect, predominantly) and low interest/pleasure (low positive affect). In past research, negative affect has improved more than positive affect during acute-phase antidepressant medication or cognitive therapy (CT). We extended this literature by differentiating depressed mood and two dimensions of low interest (general and sexual), assessing persistence of symptom differences after acute-phase CT response, and testing whether continuation treatment acted differently on depressed mood versus low interest. METHODS: We analyzed data from two randomized controlled trials. Patients with recurrent MDD first received acute-phase CT. Then, responders were randomized to 8-month continuation treatments and assessed for 16-24 additional months. RESULTS: Depressed mood and low general interest improved more than low sexual interest during acute-phase CT. Among responders, these symptom differences persisted for at least 2 years and were not changed by continuation CT or antidepressant medication. LIMITATIONS: Generalization of findings to other patient populations and treatments is uncertain. Depressed mood and low interest scales were constructed from standard symptom measures and overlapped empirically. CONCLUSIONS: Less improvement during CT, and persistent low sexual interest despite continuation treatment, highlights the need for MDD treatments more effectively targeting this positive affective symptom.
