TL;DR: Across societies, parents and adolescents tended to rate the same items as low, medium, or high, but within-dyad parent–adolescent item agreement varied widely in every society.

TL;DR: In this article, the authors reported new international findings for parent, teacher, and self-ratings on the Child Behavior Checklist, Youth Self-Report, and Teacher's Report Form, and tested the fit of syndrome models to new data from 17 societies, including previously underrepresented regions.

TL;DR: The findings underscore the importance of obtaining information from parents and teachers when evaluating and treating children, highlight the need to use multiple methods of quantifying cross-informant agreement, and provide comprehensive baselines for patterns of parent–teacher agreement across 21 societies.

TL;DR: This study standardized the questionnaires for the specific socio-cultural circle, which satisfy complex psychopathology study criteria and results in the sample suggest similarity to previous European researches.

TL;DR: Supporting across many societies in both parent and self-ratings, the 8 syndromes offer a parsimonious phenotypic taxonomy with clearly operationalized assessment criteria that can be used to assess children and youths for clinical, training, and scientific purposes.
