International Epidemiology of Child and Adolescent Psychopathology II: Integration and Applications of Dimensional Findings From 44 Societies

OBJECTIVE To build on Achenbach, Rescorla, and Ivanova (2012) by (a) reporting new international findings for parent, teacher, and self-ratings on the Child Behavior Checklist, Youth Self-Report, and Teachers Report Form; (b) testing the fit of syndrome models to new data from 17 societies, including previously underrepresented regions; (c) testing effects of society, gender, and age in 44 societies by integrating new and previous data; (d) testing cross-society correlations between mean item ratings; (e) describing the construction of multisociety norms; (f) illustrating clinical applications. METHOD Confirmatory factor analyses (CFAs) of parent, teacher, and self-ratings, performed separately for each society; tests of societal, gender, and age effects on dimensional syndrome scales, DSM-oriented scales, Internalizing, Externalizing, and Total Problems scales; tests of agreement between low, medium, and high ratings of problem items across societies. RESULTS CFAs supported the tested syndrome models in all societies according to the primary fit index (Root Mean Square Error of Approximation [RMSEA]), but less consistently according to other indices; effect sizes were small-to-medium for societal differences in scale scores, but very small for gender, age, and interactions with society; items received similarly low, medium, or high ratings in different societies; problem scores from 44 societies fit three sets of multisociety norms. CONCLUSIONS Statistically derived syndrome models fit parent, teacher, and self-ratings when tested individually in all 44 societies according to RMSEAs (but less consistently according to other indices). Small to medium differences in scale scores among societies supported the use of low-, medium-, and high-scoring norms in clinical assessment of individual children.

Prevalence and significance of minor anomalies in children with impaired development

Aim: To compare the prevalence of Waldrops minor physical anomalies in children with developmental disorders (mental retardation, hearing and visual impairment) and healthy schoolchildren. Methods: The study was carried out on a sample of 469 children (223 children with developmental disorders and 246 healthy schoolchildren). Results: Significant differences were found between the children with developmental disorders and the healthy children with regard to the number of minor anomalies and their weighted scores according to Waldrop. Multivariate discriminant analysis with two discriminative functions explained as much as 96.51% of the total variability and significantly distinguished the healthy children from the children with developmental disorders. However, no clear distinction was found between the mentally retarded children and those with visual impairment. Interrelation of the number and sum of the weighted scores of minor anomalies showed similar minor anomalies in the mentally retarded children (mean per person 3.65 and 3.82, respectively), the children with visual impairment (3.24 and 3.50), the children with hearing impairment (3.84 and 3.67) and the control group (1.70 and 1.46), although at different levels.

Testing Syndromes of Psychopathology in Parent and Youth Ratings Across Societies

As societies become increasingly diverse, mental health professionals need instruments for assessing emotional, behavioral, and social problems in terms of constructs that are supported within and across societies. Building on decades of research findings, multisample alignment confirmatory factor analyses tested an empirically based 8-syndrome model on parent ratings across 30 societies and youth self-ratings across 19 societies. The Child Behavior Checklist for Ages 6–18 and Youth Self-Report for Ages 11–18 were used to measure syndromes descriptively designated as Anxious/Depressed, Withdrawn/Depressed, Somatic Complaints, Social Problems, Thought Problems, Attention Problems, Rule-Breaking Behavior, and Aggressive Behavior. For both parent ratings (N = 61,703) and self-ratings (N = 29,486), results supported aggregation of problem items into 8 first-order syndromes for all societies (configural invariance), plus the invariance of item loadings (metric invariance) across the majority of societies. Supported across many societies in both parent and self-ratings, the 8 syndromes offer a parsimonious phenotypic taxonomy with clearly operationalized assessment criteria. Mental health professionals in many societies can use the 8 syndromes to assess children and youths for clinical, training, and scientific purposes.
