Convergent and discriminative validity of interview and questionnaire measures of personality disorder in mentally disordered offenders: a multitrait-multimethod analysis using confirmatory factor analysis

Measures of personality disorder from the International Personality Disorder Examination, Personality Diagnostic Questionnaire, and Millon Clinical Multiaxial Inventory (MCMI-II) were obtained from detained male mentally disordered offenders (N = 156), and convergent and discriminant validity were examined by confirmatory factor analysis of the multitrait-multimethod matrix. Hierarchical comparisons of models varying in their specification of trait and method variance established the appropriateness of a model supporting both convergence and discrimination across methods, but these were variable across constructs and measures. Convergence was good for avoidant, schizoid, and antisocial disorders, but poor for histrionic, narcissistic, and obsessive-compulsive disorders. Avoidant, schizoid, and schizotypal disorders were not clearly distinguishable from each other. Measurement error attributable to method variance was substantial for all instruments and for most disorders. The commonly alleged superiority of interview over questionnaire methods was not supported, and the MCMI-II demonstrated proportionately more "true" variance. However, assessment methods may be differentially sensitive to different kinds of personality disorder problems.     

Higher-order dimensions of personality disorder: hierarchical structure and relationships with the five-factor model, the interpersonal circle, and psychopathy

Two studies examined the higher-order factor structure of DSM-IV personality disorders using the International Personality Disorder Examination in male forensic psychiatric patients. In Study 1 (N = 168), exploratory factor analysis at the level of individual personality disorder criteria indicated nine primary factors. Exploratory and confirmatory factor analyses of these first-order factors supported a hierarchical structure in which two of three second-order factors covaried to yield a third-order factor. The two resulting superordinate factors were labelled Anxious-Inhibited and Acting Out. In Study 2 (N = 160), we used exploratory and confirmatory factor analyses to test hypotheses of common dimensions underlying these superordinate factors of personality disorder and superordinate factors of the five-factor model of personality, dimensions of the interpersonal circle, and psychopathy. Of three common factors, one combined Anxious-Inhibited disorders, "neurotic introversion," and hostile-submission. The other two factors of Acting Out/ psychopathy and antagonism/hostile-dominance covaried to yield a superordinate factor. Possible substrates underlying two superordinate dimensions common to normal and abnormal personality were identified in the theoretical literature.     

Mother and father self-reports of corporal punishment and severe physical aggression toward clinic-referred youth

Examined the extent to which 359 mothers and 140 fathers of clinic-referred youth (ages 2 to 17) reported using corporal punishment and severe physical aggression when asked directly via intake screening questionnaires at a community mental health center; higher prevalence rates emerged compared to families in the general population. Clinic-referred parents reported greater use of corporal punishment for younger relative to older youth, sons relative to daughters, and by single relative to married mothers. In cases with reports from both parents, mothers used corporal punishment more frequently than fathers. Demographic factors were not linked to severe physical aggression, except for mothers' treatment of sons versus daughters. After controlling for demographic factors, maternal and paternal reports of child externalizing behavior accounted for significant variance in their own and their partner's use of corporal punishment, and in mothers' use of severe physical aggression.

Onset Neighborhood Density Slows Lexical Access in High Vocabulary 30-Month Olds

There is consensus that the adult lexicon exhibits lexical competition. In particular, substantial evidence demonstrates that words with more phonologically similar neighbors are recognized less efficiently than words with fewer neighbors. How and when these effects emerge in the child's lexicon is less clear. In the current paper, we build on previous research by testing whether phonological onset density slows lexical access in a large sample of 100 English-acquiring 30-month-olds. The children participated in a visual world looking-while-listening task, in which their attention was directed to one of two objects on a computer screen while their eye movements were recorded. We found moderate evidence of inhibitory effects of onset neighborhood density on lexical access and clear evidence for an interaction between onset neighborhood density and vocabulary, with larger effects of onset neighborhood density for children with larger vocabularies. Results suggest the lexicons of 30-month-olds exhibit lexical-level competition, with competition increasing with vocabulary size.
