The authors describe a new self-report instrument, the Inventory of Depression and Anxiety Symptoms (IDAS), which was designed to assess specific symptom dimensions major depression related anxiety disorders. They created IDAS by conducting principal factor analyses in 3 large samples (college students, psychiatric patients, community adults); also examined robustness its psychometric properties 5 additional (high school college young adults, postpartum women, patients) who were not involved...
Confirmatory factor analysis was used to compare 6 models of posttraumatic stress disorder (PTSD) symptoms, ranging from 1 4 factors, in a sample 3,695 deployed Gulf War veterans (N = 1,896) and nondeployed controls 1,799). The correlated factors-intrusions, avoidance, hyperarousal, dysphoria-provided the best fit. dysphoria combined traditional markers numbing hyperarousal. Model superiority cross-validated multiple subsamples, including subset participants who were exposed traumatic combat...
The State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA; M. J. Ree, C. MacLeod, D. French, & V. Locke, 2000) was designed to assess cognitive somatic symptoms of anxiety as they pertain one's mood in the moment (state) general (trait). This study extended previous psychometric findings a clinical sample validated STICSA against well-published measure anxiety, (STAI; Spielberger, 1983). Patients (N=567) at an disorders clinic were administered battery questionnaires. results...
Shortcomings of approaches to classifying psychopathology based on expert consensus have given rise contemporary efforts classify quantitatively. In this paper, we review progress in achieving a quantitative and empirical classification psychopathology. A substantial literature indicates that is generally more dimensional than categorical. When the discreteness versus continuity treated as research question, opposed being decided matter tradition, evidence clearly supports hypothesis...
Psychological tests typically include a response scale whose purpose it is to organize and constrain the options available respondents facilitate scoring. One such Likert scale, which initially was introduced have specific 5-point form. In practice, scales varied considerably in nature number of options. However, relatively little consensus exists regarding several questions that emerged use Likert-type items. First, there “psychometrically optimal” options? Second, better an even or odd...
The current study examines the relations among contemporary models of pathological and normal range personality traits. Specifically, we report on (a) conjoint exploratory factor analyses Computerized Adaptive Test Personality Disorder static form (CAT-PD-SF) with Inventory for Diagnostic Statistical Manual Mental Disorders, fifth edition NEO Inventory-3 First Half, (b) unfolding hierarchical three measures in a large general psychiatric outpatient sample (n = 628; 64% Female). A five-factor...
This paper introduces a new classification of mental illness, the Hierarchical Taxonomy Of Psychopathology (HiTOP). It aims to address several major shortcomings traditional taxonomies and provide better framework for researchers clinicians.
Assessment of personality disorders (PD) has been hindered by reliance on the problematic categorical model embodied in most recent Diagnostic and Statistical Model Mental Disorders (DSM), lack consensus among alternative dimensional models, inefficient measurement methods. This article describes rationale for early results from a multiyear study funded National Institute Health that was designed to develop an integrative comprehensive efficient measure PD trait dimensions. To accomplish...
Objective: Diagnosis is a cornerstone of clinical practice for mental health care providers, yet traditional diagnostic systems have well-known shortcomings, including inadequate reliability, high comorbidity, and marked within-diagnosis heterogeneity. The Hierarchical Taxonomy Psychopathology (HiTOP) data-driven, hierarchically based alternative to classifications that conceptualizes psychopathology as set dimensions organized into increasingly broad, transdiagnostic spectra. Prior work has...
Age and gender differences in narcissism have been studied often. However, considering the rich history of research accompanied by its diverging conceptualizations, little is known about age across various measures. The present study investigated their interactions eight widely used instruments (i.e., Narcissistic Personality Inventory, Hypersensitive Narcissism Scale, Dirty Dozen, Psychological Entitlement Disorder Symptoms from
Abstract Scale construction is a growth enterprise in the psychological literature. Unfortunately, many measures promise much but are severely limited by inadequacies of their conceptualization and execution. In this paper, model for developing scales presented that rooted traditions construct validity classical test theory informed modern psychometric methods. Construct conceptualized as guiding principle each three phases scale development, focused on (i) development initial item pool,...
Background Psychiatric co-morbidity is extensive in both psychiatric settings and the general population. Such challenges whether DSM-based mental disorders serve to effectively carve nature at its joints. In response, a substantial literature has emerged showing that small number of broad dimensions – internalizing, externalizing psychoticism can account for much observed covariation among common disorders. However, location personality within this emerging metastructure only recently been...
Very little is known about the daily stability and fluctuation of personality pathology. To address this gap in knowledge, we investigated naturalistic manifestation pathology over course 100 days. A group individuals (N = 101) diagnosed with any disorder (PD) completed a diary study consecutive days (Mdn 94 days, range 33-101 days). Participants ratings 30 manifestations Patterns variability were then examined. Results indicated that individual PD domains variable across differed widely...
Background Observed co-morbidity among the mood and anxiety disorders has led to development of increasingly sophisticated dimensional models represent common unique features these disorders. Patients often present primary care settings with a complex mixture anxiety, depression somatic symptoms. However, relatively little is known about how symptoms fit into existing models. Method We examined structure 91 in sample 5433 patients drawn from 14 countries. One-, two- three-factor lower-order...
This study was conducted to establish (a) the stability of DSM-5 Section III personality disorder (PD) traits, (b) whether these traits predict future psychosocial functioning, and (c) changes in track with functioning across time. Ninety-three outpatients (61% female) diagnosed at least 1 PD completed patient-report measures 2 time-points (M time between assessments = 1.44 years), including Personality Inventory for several functioning. Effect sizes rank-order mean-level change were...
In this article, we describe the collaborative process that is underway to develop measures for Hierarchical Taxonomy of Psychopathology (HiTOP). The HiTOP model has generated much interest in psychiatric literature recent years, but research applications and clinical translation require are specifically keyed model. To end, Measures Development Workgroup been engaged a effort both questionnaire interview methods (a) tied elements structure, (b) provide one means testing structure. work...
Recent hierarchical models suggest that both general and specific components are needed to fully represent the variation observed among mood anxiety disorders. However, little is known about relative size, severity, psychological meaning of these components. We studied features through bifactor modeling symptoms from Inventory Depression Anxiety Symptoms [IDAS; Watson et al., 2007] in 362 community adults, 353 psychiatric patients, 673 undergraduates. Results revealed although all IDAS...
The DSM-IV-TR currently conceptualizes personality disorders (PDs) as categorical syndromes that are distinct from normal personality.However, an alternative dimensional viewpoint is PDs maladaptive expressions of general traits.The perspective postulates pathology exists at a more extreme level the latent trait than does personality.This hypothesis was examined using item response theory analyses comparing scales two instruments -the Dimensional Assessment Personality Pathology-Basic...
Background DSM-5 may mark the shift from a categorical classification of personality pathology to dimensional system. Although and conceptualizations are often viewed as competing, it is possible develop categories (prototypes) combinations dimensions. Robust prototypes could bridge dimensions within single Method To explore prototype structure robustness, we used finite mixture modeling identify empirically derived large sample ( n =8690) individuals four settings (clinical, college,...
