This study investigated hospitalized adolescents (57 girls; 46 boys; mean age = 14 years, 8 months) and their fathers and mothers to ascertain the degree of correspondence (by gender of parent and child) on ratings of total symptoms and of internalizing and externalizing psychopathology. Parents (especially mothers) reported higher levels of symptom severity than their offspring; girls' ratings were more severe than boys'. Whereas interparent correspondence was essentially the same in ratings of daughters, mother-son convergence was generally higher than father-son correspondence. Boys and their parents did not differentiate internalizing from externalizing disorders; girls and parents were better able to discriminate between these types of psychopathology.
Principal components analysis applied to the Delirium Rating Scale-Revised-98 contributes to understanding the delirium construct. Using a multisite pooled international delirium database, the authors applied confirmatory factor analysis to Delirium Rating Scale-Revised-98 scores from 859 adult patients evaluated by delirium experts (delirium, N=516; nondelirium, N=343). Confirmatory factor analysis found all diagnostic features and core symptoms (cognitive, language, thought process, sleep-wake cycle, motor retardation), except motor agitation, loaded onto factor 1. Motor agitation loaded onto factor 2 with noncore symptoms (delusions, affective lability, and perceptual disturbances). Factor 1 loading supports delirium as a single construct, but when accompanied by psychosis, motor agitation's role may not be solely as a circadian activity indicator.
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
