Psychopathy is a clinical construct defined by a cluster of personality traits and behaviors, including grandiosity, egocentricity, deceptiveness, shallow emotions, lack of empathy or remorse, irresponsibility, impulsivity, and a tendency to ignore or violate social norms. The majority of empirical research on psychopathy involves forensic…

Interest in conceptualizing the interpersonal style of individuals who engage in serious antisocial behavior has increased in recent years. This study examines the personality, psychopathological, and behavioral correlates of interpersonal dominance and warmth, as operationalized via scales of the Personality Assessment Inventory (L. Morey, 2007),…

This article presents information on the development and validation of the Facial Expression Coding System (FACES; A. M. Kring & D. Sloan, 1991). Grounded in a dimensional model of emotion, FACES provides information on the valence (positive, negative) of facial expressive behavior. In 5 studies, reliability and validity data from 13 diverse…

In 3 studies, the authors developed and began to validate a measure of the propensity to act rashly in response to positive affective states (positive urgency). In Study 1, they developed a content-valid 14-item scale, showed that the measure was unidimensional, and showed that positive urgency was distinct from impulsivity-like constructs…

The validity of intuitive classifications of experienced diagnosticians was examined for 10 experienced diagnosticians evaluating child behavior problems. Results showed that intuitive prototypes corresponded poorly with empirical core syndromes in the assessment system of T. M. Achenbach and others. Reasons for differences are discussed. (SLD)

This second article of the special section on chaos theory addresses implications of the definition of chaotic behavior for its measurement. The requirements to test the presence of chaotic relations among variables are in agreement with the conceptual and methodological hallmarks of behavioral assessment. (SLD)

An empirical typology of behavior styles was developed to define distinct variations of healthy, marginal, at-risk, and maladjusted behavior using a stratified national sample of 1,400 youths aged 5 to 17 years. Results are compared with recent epidemiological studies, and application of the typology is demonstrated. (SLD)

The usefulness of the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) was examined for 162 delinquent boys in a state training school who were compared with 805 nondelinquent male adolescents and the original MMPI sample of 7,783 male adolescents. The most useful scales are discussed. (SLD)

The contributions of specific scales of the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) to the classification of 180 adolescent substance abusers into groups characterized by aspects of behavioral control were studied. Seven scales made significant contributions to the classification of substance abusers into three groups, with…

Two studies involving 98 prisoners and 92 undergraduates examined whether increased attention to interpersonal behaviors would improve assessments of the personality core underlying psychopathology. Twenty-one items were developed as the Interpersonal Measure of Psychopathology. Measurement of interpersonal behavior appears to improve prediction…

An empirically based paradigm for assessment and taxonomy of child, adolescent, and young adult behavioral and emotional problems is outlined, and the standardization procedures used to assess problems reported by different informants for large clinical samples are discussed. The application of the paradigm to new cases is considered. (SLD)

Psychometric properties of a laboratory paradigm for measuring stealing, property destruction, and cheating were explored, and the viability of the construct of covert antisocial behavior was studied in 98 children with attention-deficit hyperactivity disorder and 78 comparisons. Psychometric and ethical issues in assessment of covert behavior are…

In 3 studies involving a total of 305 undergraduates, the Antisocial Practices (ASP) scale of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) exhibited convergent and discriminant validity with other measures of personality. The ASP and the Psychopathic Deviant scale appear to measure different facets of psychopathy. (SLD)

Validities of the Harris-Lingoes subscales and MacAndrew scale of the Minnesota Multiphasic Personality Inventory (MMPI) in estimation of criterion measures were evaluated with 177 adolescent inpatients. Results were consistent with predictions that excitatory and inhibitory scales and subscales would be related to criteria of behavioral control…

This introduction to a special section provides the basic definitions and presents the measurement approaches and data analytic techniques that are collectively referred to as chaos theory. The conceptualization and assessment of unstable behavioral disorders can be strengthened by incorporating elements of chaos theory. (SLD)
