The Generalizability of the Youth Self-Report Syndrome Structure in 23 Societies.

As a basis for theories of psychopathology, clinical psychology and related disciplines need sound taxonomies that are generalizable across diverse populations. To test the generalizability of a statistically derived 8-syndrome taxonomic model for youth psychopathology, confirmatory factor analyses (CFAs) were performed on the Youth Self-Report (T. M. Achenbach & L. A. Rescorla, 2001) completed by 30,243 youths 11-18 years old from 23 societies. The 8-syndrome taxonomic model met criteria for good fit to the data from each society. This was consistent with findings for the parent-completed Child Behavior Checklist (Achenbach & Rescorla, 2001) and the teacher-completed Teachers Report Form (Achenbach & Rescorla, 2001) from many societies. Separate CFAs by gender and age group supported the 8-syndrome model for boys and girls and for younger and older youths within individual societies. The findings provide initial support for the taxonomic generalizability of the 8-syndrome model across very diverse societies, both genders, and 2 age groups.

Cross-Informant Agreement Between Parent-Reported and Adolescent Self-Reported Problems in 25 Societies

We used population sample data from 25 societies to answer the following questions: (a) How consistently across societies do adolescents report more problems than their parents report about them? (b) Do levels of parent–adolescent agreement vary among societies for different kinds of problems? (c) How well do parents and adolescents in different societies agree on problem item ratings? (d) How much do parent–adolescent dyads within each society vary in agreement on item ratings? (e) How well do parent–adolescent dyads within each society agree on the adolescents deviance status? We used five methods to test cross-informant agreement for ratings obtained from 27,861 adolescents ages 11 to 18 and their parents. Youth Self-Report (YSR) mean scores were significantly higher than Child Behavior Checklist (CBCL) mean scores for all problem scales in almost all societies, but the magnitude of the YSR–CBCL discrepancy varied across societies. Cross-informant correlations for problem scale scores varied more across societies than across types of problems. 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. In all societies, both parental noncorroboration of self-reported deviance and adolescent noncorroboration of parent-reported deviance were common. Results indicated many multicultural consistencies but also some important differences in parent–adolescent cross-informant agreement. Our findings provide valuable normative baselines against which to compare multicultural findings for clinical samples.

Over- and Undercontrolled Clinic Referral Problems of Jamaican and American Children and Adolescents: The Culture General and the Culture Specific

Child behavior problems and corresponding clinic referral patterns may be significantly influenced by cultural factors. Prevailing values and childrearing practices within a culture may discourage development of some child problems while fostering others. We explored this possibility, focusing on clinic referral problems of two different societies: (a) Jamaica, where the Afro-British culture discourages child aggression and other undercontrolled behavior and possibly fosters inhibition and other overcontrolled behavior, and (b) the United States, where undercontrolled child behavior is seemingly more generally accepted. We coded clinic-referred problems listed by parents of Jamaican and American youngsters (N = 720). Cross-cultural differences were striking: Overcontrolled problems were noted more often for Jamaican than American youngsters, whereas the converse was true for undercontrolled problems. These and other findings suggest that factors such as culture and sex may be linked to substantial differences in the problems for which youngsters of different countries are treated in clinics.

Parent–Teacher Agreement on Children's Problems in 21 Societies

Parent–teacher cross-informant agreement, although usually modest, may provide important clinical information. Using data for 27,962 children from 21 societies, we asked the following: (a) Do parents report more problems than teachers, and does this vary by society, age, gender, or type of problem? (b) Does parent–teacher agreement vary across different problem scales or across societies? (c) How well do parents and teachers in different societies agree on problem item ratings? (d) How much do parent–teacher dyads in different societies vary in within-dyad agreement on problem items? (e) How well do parents and teachers in 21 societies agree on whether the childs problem level exceeds a deviance threshold? We used five methods to test agreement for Child Behavior Checklist (CBCL) and Teachers Report Form (TRF) ratings. CBCL scores were higher than TRF scores on most scales, but the informant differences varied in magnitude across the societies studied. Cross-informant correlations for problem scale scores varied moderately across societies studied and were significantly higher for Externalizing than Internalizing problems. Parents and teachers tended to rate the same items as low, medium, or high, but within-dyad item agreement varied widely in every society studied. In all societies studied, both parental noncorroboration of teacher-reported deviance and teacher noncorroboration of parent-reported deviance were common. Our 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.

Is it prudent to administer all items for each Child Behavior Checklist cross-informant syndrome? Evaluating the psychometric properties of the Youth Self-Report dimensions with confirmatory factor analysis and item response theory

Through surveying of children in 10 nations with parent, teacher, and Youth Self-Report (YSR) forms of the Child Behavior Checklist (CBCL), cross-informant syndromes (CISs) were derived and cross-validated by sample-dependent methodology. Generalizing CBCL syndromes and norms to nations excluded from its normative sample is problematic. This study used confirmatory factor analyses (CFAs) to test factor model fit for CISs on the YSR responses of 625 Jamaican children ages 11 to 18 years. Item response theory (IRT), a sample-independent methodology, was used to estimate the psychometric properties of individual items on each dimension. CFAs indicated poor to moderate model-to-data fit. Across all syndromes, IRT analyses revealed that more than 3/4 of the cross-informant items yielded little information. Eliminating such items could be cost effective in terms of administration time yet improve the measures discrimination across syndrome severity levels.

Are the indicators for the Language and Reasoning Subscale of the Early Childhood Environment Rating Scale-Revised psychometrically appropriate for Caribbean classrooms?

Evaluating the psychometric properties of the indicators that comprise the Early Childhood Environment Rating Scale‐Revised (ECERS‐R) language‐reasoning scale from an item response theory (IRT) perspective on a sample of observations from 334 Caribbean classrooms, Stout’s procedure revealed that all indicators on this dimension are not part of a single essentially unidimensional construct. IRT‐based factor analyses on the indicator scores yielded two factors – named Language‐Reasoning Activities and Language‐Reasoning Materials. IRT analyses conducted on these two factors revealed that their indicators provide adequate psychometric information and have no floor effects – although they demonstrate evidence for ceiling effects. IRT also revealed that at least within the Caribbean context: (a) the ECERS‐R authors have ordered the indicators inappropriately; (b) administration of all indicators is unnecessary; and (c) equally weighting indicators might yield spurious results. IRT‐based scoring might improve the psychometric soundness of indicators on this ECERS‐R scale.

Do Problems of Clinic-Referred African-American Children Overlap with the Child Behavior Checklist?

Many factors contribute to childrens psychopathology. African-American children, members of the largest U.S. minority group, are reportedly at high risk for psychopathology, but researchers and developers of diagnostic measures seldom focus on them. We surveyed the clinic records of 1,605 African-American children, ages 4–18. Coders recorded childrens problems, their gender, and age. They coded childrens problems according to the Child Behavior Checklist (CBCL). Overlap between some problems African-American children presented and CBCL items emerged but other problems did not match CBCL items. For problems which matched the CBCL, associations between such problems and childrens age emerged and boys had more problems than girls. The content and cultural validity of the CBCL for African-American children may, however, be questionable.

Assessment of Behavioral and Emotional Strengths in Black Children: Development of the Behavioral Assessment for Children of African Heritage

Absence of culturally relevant measures of Black childrens strengths inhibits psychometrically sound strength-based assessment, research, and appropriate use of strengths as scaffolds or targets for clinical intervention. Moreover, the sparse research literature on Black children is primarily deficit focused. Beginning to address these problems, considerable input was sought from the Black community in constructing behavioral and emotional strength forms for Black children. Exploratory factor analyses conducted separately on 559 parent reports, 489 teacher reports, and 417 adolescent self-reports revealed two unidimensional cross-informant factors labeled Resilience and Self-Regulation and Prosocial Behavior. Item response theory analyses revealed invariance across gender, socioeconomic status, and age, but variance across informant type and referral status, and that most items provide sufficient psychometric information to warrant retention for clinical assessment and research.

Adult Perspectives on Behavior and Emotional Problems in African American Children

Using vignettes describing African American children with internalizing (e.g., withdrawal) versus externalizing (e.g., quarrels) problems, parents, teachers, and clinicians made judgments regarding problem seriousness, prognosis, etiology, referral, and intervention needs. Opinions of parents, teachers, and clinicians differed markedly, especially with regard to judgments about children with externalizing problems. Black raters’ ratings significantly differed from those of Whites, especially for seriousness and prognostic judgments with regard to the problems. The findings suggest that interventionists who address problems that African American youth present should attend to the attitudes and judgments of adults who report on such problems. Clinicians can simultaneously harness appropriate judgments and attitudes and decrease counterproductive beliefs and behavior in their interventions with Black children.

Dimensionality and Psychometric Invariance of the Youth Self-Report Form of the Child Behavior Checklist in Cross-National Settings

The Youth Self-Report Forms (YSRs) factor model was derived from traditional exploratory factor analytical procedures. Assuming appropriate model specification, psychometrically invariant items, and that its items provide useful psychometric information across nations omitted from its normative samples, the YSR is widely used in cross-national studies of nonreferred children. Item response theory analytical procedures reveal (a) 2 dimensions partly overlapping with the YSRs Internalizing and Externalizing second-order factors; (b) variance (i.e., differential item functioning) in how well a few items discriminate for nonreferred children across two nations; and (c) variance in estimating severity levels in children with identical psychopathological severity cross-nationally. Addressing psychometric variance, limiting redundancy, and matching childrens psychopathological severity levels with items measuring this severity might promote more accurate and economical assessment.
