The Alternative DSM-5 Model for Personality Disorders (AMPD) consists of level of personality functioning (Criterion A) and maladaptive personality traits (Criterion B).

"What are you doing?" and "How is it going?" are foundational questions we can ask of agents. They elicit answers that illuminate aspects of well-doing, or felicitous action, by directing attention to an agent's personal projects. Personal projects are constitutive elements of daily existence and are consequential for a…

Many latent traits in the human sciences have a hierarchical structure. This study aimed to develop a new class of higher order item response theory models for hierarchical latent traits that are flexible in accommodating both dichotomous and polytomous items, to estimate both item and person parameters jointly, to allow users to specify…

The present research examined five-year-old children's psychological self-concepts. Non-linear factor analysis was used to model the latent structure of the children's self-view questionnaire (CSVQ; Eder, 1990), a measure of children's self-concepts. The coherence and reliability of the emerging factor structure indicated that young children are…

In 1921, Carl Jung wrote about four different types of personality, identified 24 centuries ago by Hippocrates. He theorized that these differences were not abnormalities in personality.

Studies in the field of personality have systematically found gender differences in two of the three dimensions of the Eysenck model: neuroticism and psychoticism. This study aims to analyze these differences in the Eysenck Personality Questionnaire--Revised (EPQ-R) scales using differential item functioning (DIF) techniques to determine whether…

The frequency, origin, and interpretative implications of elevation differences on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) clinical and restructured clinical (RC) scales were examined. Two large clinical samples consisting of 1,770 outpatients and 2,438 inpatients were used for this study. Three potential factors…

The present study investigated theoretically and empirically derived similarities and differences between the constructs of enduring happiness and self-esteem. Participants (N = 621), retired employees ages 51-95, completed standardized measures of affect, personality, psychosocial characteristics, physical health, and demographics. The relations…

A new assessment scheme--the Short-Term Assessment of Risk and Treatability (START)-- presents a workable method for assessing risks to self and others encountered in mentally and personality disordered clients. This study aimed to demonstrate (a) prevalence and severity of risk behaviors measured by the START, (b) psychometric properties of…
