This article places one of Jerry Wiggins' contributions to the Minnesota Multiphasic Personality Inventory (MMPI), his content scales, in the twin contexts of past and recent research, and of Wiggins' own preoccupations growing out of the interpersonal point of view. It highlights Wiggins' perspective on the position of the person in the process…

The popular factor analytic procedure of putting unities in the main diagonal and retaining all factors with an eigenvalue greater than one is criticized with respect to the number of factors retained and resultant estimates of common variance. Ways of avoiding these difficulties are discussed. (JKS)

We introduce a personality inventory designed to measure six major dimensions of personality derived from lexical studies of personality structure. The HEXACO Personality Inventory (HEXACO-PI) consists of 24 facet-level personality trait scales that define the six personality factors named Honesty-Humility (H), Emotionality (E), Extraversion (X),…

The parameters of full-information item factor models of varying dimensionality and mixed-measurement models of varying numbers of latent classes were estimated in 1,000 responses to a measure of Positive Interpersonal Engagement. The most appropriate representation of the data and deciding between mixed-measurement and dimensional representations…

Common items, items which appear on several scales on psychological tests, are investigated in this study. It is concluded that the common item problem is not a serious one in personality measurement. (Author/JKS)

The present research examined the amount and kind of personality measured within four sets of personality disorder (PD) scales. Three samples of undergraduate students (Ns = 326, 537, and 617) completed at least one PD measure and a combined interpersonal circumplex model (ICM) and five-factor model (FFM) measure. The FFM dimensions were found to…

This study describes the relation between personality items' validities, defined as the items' correlations with acquaintance ratings on the Big 5 personality factors, and other itemmetric properties including ambiguity, syntactic complexity, social desirability, content, and trait indicativity. Five external validity coefficients for each item on…

Two longitudinal studies involving 29 raters concerning the construct validity, temporal stability, and interrater reliability of the latent common factors underlying subjective assessments by human raters of personality traits in the stumptail macaque and the zebra finch illustrate the use of generalizability analysis to test prespecified…

To determine the higher order factors defined by scales of the Interpersonal Style Inventory, data from two male samples and one female sample were separately analyzed. The five rotated factors established were highly similar across samples. (Author/JKS)

The structure of voters' affective reactions and trait attributions to national political figures was studied through 3-mode factor analysis of ratings by 78 college students of 16 political figures. The factor analysis suggested that positive and negative affect and affect and trait factors were distinct but correlated. (SLD)

A sample of gang members and a comparison group of club boys are compared on 11 factors from the Objective-Analytic Personality Factor Battery. The findings are examined in light of several hypotheses drawn from theories of personality and of gang delinquency. (Author/CTM)
