The expectation that Chinese people present distress somatically is a central prediction of cultural psychopathology and has been the subject considerable theoretical speculation. At same time, empirical studies have infrequent yielded mixed results. authors examined symptom presentation in (n=175) Euro-Canadian (n=107) outpatients, using spontaneous problem report, structured clinical interview, questionnaire methods. All 3 methods cross-culturally equivalent somatic psychological...
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...
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...
The 20‐item Toronto Alexithymia Scale (TAS‐20) was developed in previous research to measure a general dimension of alexithymia with three inter correlated factors. These factors reflect distinct facets the construct: (1) difficulty identifying feelings and distinguishing them from bodily sensations emotion, (2) describing others, (3) an externally orientated style thinking. This study tested three‐factor model for TAS‐20, using confirmatory factor analysis, separate samples young adults...
The NEO Personality Inventory (NEO-PI) was administered to a sample of unipolar, nonpsychotic depressed outpatients receiving pharmacotherapy. Fifty-seven patients were assessed on two occasions—at treatment entry (Time 1) and 3 months following initiation 2). Neuroticism (N) Extraversion (E) dimension scores altered by the depressive episode, whereas Openness (O), Conscientiousness (C), Agreeableness (A) dimensions not altered. N for recovered at Time 2 least 1 standard deviation above that...
Abstract The relation between alexithymia and both the domain facet level of five-factor model (FFM) personality was examined in a sample 101 university students by using Twenty-Item Toronto Alexithymia Scale (TAS-20; Bagby, Taylor, & Parker, 1994) Revised NEO Personality Inventory (Costa McCrae, 1992c). Consistent with construct, TAS-20 positively correlated Neuroticism (N) negatively Extraversion (E) Openness (O), whereas no significant relations were found Agreeableness (A)...
Section 3 of the fifth edition Diagnostic and Statistical Manual Mental Disorders ( DSM-5) includes a hybrid model personality pathology, in which dimensional traits are used to derive one seven categorical disorder diagnoses. The Personality Inventory for DSM-5 (PID-5) was developed by workgroup their consultants produce freely available instrument assess within this new system. To date, psychometric properties PID-5 have been evaluated primarily undergraduate student community adult...
The DSM-5 Personality and Disorders workgroup their consultants have developed the 220-item, self-report Inventory for (PID-5) direct assessment of proposed personality trait system DSM-5; however, most practicing clinical psychologists will likely continue to rely on separate omnibus measures index symptoms traits associated with psychopathology. Minnesota Multiphasic Inventory-2 Restructured Form (MMPI-2-RF) is one such measure assesses Psychopathology Five (PSY-5) domains, which are...
The current article reports on the development, psychometric properties, and external validity of an informant-report form Personality Inventory for DSM-5 (the PID-5-IRF). Using data from two nationally representative samples, as well elevated-risk community sample, we report PID-5-IRF item characteristics, scale superordinate factor structure, correlations with other measures. replicates structure self-report has relationships measures (including PID-5 a widely used Big Five measure) that...
