The Language-Based Assessment Model Library
Language-based assessments (LBAs), quantitative estimates of scientific constructs based on language, have advanced methods in the psychological and social sciences for more than a decade. LBAs based on individuals’ prompted descriptions analyzed with large language models to produce scores of their psychological states and traits have shown strong convergence with the corresponding rating scales ( r > .80) and have often surpassed rating scales …
Validation of the Hierarchical Taxonomy of Psychopathology Brief Report (HiTOP-BR) in Two German-Speaking Samples
601). Confirmatory factor analyses and exploratory factor analyses with target rotation supported the hypothesized six-factor structure across both samples, although observed cross-loadings suggested scope for item refinement. Scalar measurement invariance was established between the clinical and nonclinical samples. Scale scores showed acceptable to good reliability (ω = .77-.88). Convergent and discriminant validity were examined via correlatio…
Do Cognitive Functions Belong in the Hierarchical Taxonomy of Psychopathology Model? A Meta-Analysis
Cognitive dysfunction is essential to conceptualizing, defining, and assessing much of psychopathology. Despite this prominence, cognitive abilities are not included in the prevailing empirically based classification system: the Hierarchical Taxonomy of Psychopathology (HiTOP). This gap exists because the factor-analytic literature the HiTOP is based on has solely used reporter measures rather than neuropsychological tests needed to measure cogni…
Psychometric Properties of the Neural Response to Rewards and Errors Across Mid‐ to Late‐Adolescence
Event‐related potential (ERP) measures of reward‐ and error‐related brain activity have been used to elucidate neural mechanisms contributing to the development of psychopathology. Adolescence is a critical developmental period that is associated with changes in ERP reward‐ and error‐related brain activity. However, there is a paucity of within‐subject research examining whether the reliability of ERP measures is the same or changes across adoles…
Effects of Daily Posttraumatic Stress Disorder Symptoms on Heart Rate Variability
OBJECTIVE: Posttraumatic stress disorder (PTSD) is common, debilitating, and associated with an increased risk of health problems, including cardiovascular disease. PTSD is related to poor autonomic function indicated by reduced heart rate variability (HRV). However, very little work has tested the timescale or direction of these effects, given that most evidence comes from cross-sectional studies. Documentation of when effects occur and in what …
Multi-method longitudinal investigation of the general factor of child temperament (GFT)
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 de…
Is personality stable and symptoms fleeting? A longitudinal comparison in adolescence
Translating the hierarchical taxonomy of psychopathology (HiTOP) from potential to practice
The Hierarchical Taxonomy of Psychopathology (HiTOP) is a novel diagnostic system grounded in empirical research into the architecture of mental illness. Its basic units are continuous dimensions-as opposed to categories-that are organized into a hierarchy according to patterns of symptom co-occurrence observed in quantitative studies. Previous HiTOP discussions have focused on existing evidence regarding the model's structure and ability to acco…
Differential outcomes of tonic and phasic irritability in adolescent girls
BACKGROUND: Irritable mood is a transdiagnostic clinical feature that is present in multiple psychiatric disorders. Although irritability is frequently examined as a unitary construct, two dimensions of irritability, tonic (i.e., irritable mood) and phasic (i.e., temper outbursts), have been hypothesized. However, few studies have examined whether tonic and phasic irritability are empirically separable and predict different forms of psychopatholo…
Does maternal psychopathology bias reports of offspring symptoms? A study using moderated non‐linear factor analysis
BACKGROUND: Mood-state biases in maternal reports of emotional and behavioral problems in their children have been a major concern for the field. However, few studies have addressed this issue from a measurement invariance perspective. METHODS: Using data from baseline assessment of the Adolescent Brain Cognitive Development (ABCD) study (n = 8,507 mother-child dyads; youth aged 9-11 years), we examined how dimensions of maternal psychopathology,…
Positive and negative affect in the daily life of world trade center responders with PTSD
Results suggest that for chronic PTSD among disaster responders, positive emotions are not inhibited across daily living. Such findings add to evidence suggesting that PA reduction may not be diagnostically relevant to PTSD, whereas NA remains an important target for therapeutic interventions. Moreover, results show that WTC responders can experience and benefit from positive emotion, even if they continue to have PTSD symptoms. (PsycINFO Databas…
Handgrip Strength of World Trade Center (WTC) Responders
Background : This study sought to examine whether handgrip strength (HGS), a measure of muscle strength and a biomarker of aging, was associated with post-traumatic stress disorder (PTSD) in a cohort of World Trade Center (WTC) responders at midlife. Methods : HGS was assessed utilizing a computer-assisted hand dynamometer administered to a consecutive sample of men and women ( n = 2016) who participated in rescue and recovery efforts following t…
Electrocortical Responses to Emotional Stimuli in Psychotic Disorders
Emotion dysfunction has long been considered a cardinal feature across psychotic disorders, including schizophrenia and affective psychosis. However, few studies have used objective markers of emotional function to compare psychotic disorders to one another, and fewer studies have examined such markers within a longitudinal framework. Here, we examine one objective marker of emotional responsivity, the late positive potential (LPP), which is a ce…

Posttraumatic Stress Disorder and the Risk of Respiratory Problems in World Trade Center Responders
OBJECTIVE: Posttraumatic stress disorder (PTSD) is associated with high medical morbidity, but the nature of this association remains unclear. Among responders to the World Trade Center (WTC) disaster, PTSD is highly comorbid with lower respiratory symptoms (LRS), which cannot be explained by exposure alone. We sought to examine this association longitudinally to establish the direction of the effects and evaluate potential pathways to comorbidit…
The Brief Experiential Avoidance Questionnaire
The 62-item Multidimensional Experiential Avoidance Questionnaire (MEAQ) was recently developed to assess a broad range of experiential avoidance (EA) content. However, practical clinical and research considerations made a briefer measure of EA desirable. Using items from the original 62-item MEAQ, a 15-item scale was created that tapped content from each of the MEAQ's six dimensions. Items were selected on the basis of their performance in 3 sam…
Longitudinal Study of the Impact of Psychological Distress Symptoms on New-Onset Upper Gastrointestinal Symptoms in World Trade Center Responders
OBJECTIVES: Research on the health of workers involved in the cleanup after the attack on the World Trade Center (WTC) on September 11, 2001, has documented high rates of psychological distress and upper gastrointestinal (GI) symptoms. The current article examines the concurrent and longitudinal associations of psychological distress with development of new-onset upper GI symptoms in a large sample of WTC responders. METHODS: A cohort of 10,953 W…
Neuroticism and common mental disorders
Personality and Depression
Understanding the association between personality and depression has implications for elucidating etiology and comorbidity, identifying at-risk individuals, and tailoring treatment. We discuss seven major models that have been proposed to explain the relation between personality and depression, and we review key methodological issues, including study design, the heterogeneity of mood disorders, and the assessment of personality. We then selective…
Development of a measure of experiential avoidance
Experiential avoidance (EA) has been conceptualized as the tendency to avoid negative internal experiences and is an important concept in numerous conceptualizations of psychopathology as well as theories of psychotherapy. Existing measures of EA have either been narrowly defined or demonstrated unsatisfactory internal consistency and/or evidence of poor discriminant validity vis-à-vis neuroticism. To help address these problems, we developed a r…
Linking "big" personality traits to anxiety, depressive, and substance use disorders
We performed a quantitative review of associations between the higher order personality traits in the Big Three and Big Five models (i.e., neuroticism, extraversion, disinhibition, conscientiousness, agreeableness, and openness) and specific depressive, anxiety, and substance use disorders (SUD) in adults. This approach resulted in 66 meta-analyses. The review included 175 studies published from 1980 to 2007, which yielded 851 effect sizes. For a…
Development and validation of the Inventory of Depression and Anxiety Symptoms (Idas).
The authors describe a new self-report instrument, the Inventory of Depression and Anxiety Symptoms (IDAS), which was designed to assess specific symptom dimensions of major depression and related anxiety disorders. They created the IDAS by conducting principal factor analyses in 3 large samples (college students, psychiatric patients, community adults); the authors also examined the robustness of its psychometric properties in 5 additional sampl…
