International comparisons of behavioral and emotional problems in preschool children: parents’ reports from 24 societies

International comparisons were conducted of preschool children’s behavioral and emotional problems as reported on the Child Behavior Checklist for Ages 1½–5 by parents in 24 societies (N¼19,850). Item ratings were aggregated into scores on syndromes; Diagnostic and Statistical Manual of Mental Disorders–oriented scales; a Stress Problems scale; and Internalizing, Externalizing, and Total Problems scales. Effect sizes for scale score differences among the 24 societies ranged from small to medium (3–12%). Although societies differed greatly in language, culture, and other characteristics, Total Problems scores for 18 of the 24 societies were within 7.1 points of the omnicultural mean of 33.3 (on a scale of 0–198). Gender and age differences, as well as gender and age interactions with society, were all very small (effect sizes<1%). Across all pairs of societies, correlations between mean item ratings averaged .78, and correlations between internal consistency alphas for the scales averaged .92, indicating that the rank orders of mean item ratings and internal consistencies of scales were very similar across diverse societies

Parent-Adolescent Cross-Informant Agreement in Clinically Referred Samples: Findings From Seven Societies

To conduct international comparisons of parent-adolescent cross-informant agreement in clinical samples, we analyzed ratings on the Child Behavior Checklist (CBCL) and Youth Self-Report (YSR) for 6,762 clinically referred adolescents ages 11-18 from 7 societies (M = 14.5 years, SD = 2.0 years; 51% boys). Using CBCL and YSR data, we asked the following questions: (a) Do parents report more problems for their adolescent children than the adolescents report about themselves? (b) How do cross-informant correlations (rs) for scale scores differ by problem type and by society? (c) How well do parents and adolescents, on average, agree regarding which problems they rate as low, medium, or high? (d) How does within-dyad item agreement vary within and between societies? (e) How do societies vary in dichotomous cross-informant agreement with respect to the deviance status of the adolescents? CBCL and YSR scores were quite similar, with small and inconsistent informant effects across societies. Cross-informant rs averaged .47 across scales and societies. On average, parents and adolescents agreed well regarding which problem items received low, medium, or high ratings (M r = .87). Mean within-dyad item agreement was moderate across all societies, but dyadic agreement varied widely within every society. In most societies, adolescent noncorroboration of parent-reported deviance was more common than parental noncorroboration of adolescent-reported deviance. Overall, somewhat better parent-adolescent agreement and more consistency in agreement patterns across diverse societies were found in these seven clinical samples than in population samples studied using the same methods
