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 adolescent's 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. (Contains 5 tables and 1 figure.)

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 Teacher's 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.

There is a growing need for multicultural collaboration in child mental health services, training, and research. To facilitate such collaboration, this study tested the 8-syndrome structure of the Child Behavior Checklist (CBCL) in 30 societies. Parents' CBCL ratings of 58,051 6- to 18-year-olds were subjected to confirmatory factor analyses, which were conducted separately for each society. Societies represented Asia; Africa; Australia; the Caribbean; Eastern, Western, Southern, and Northern Europe; the Middle East; and North America. Fit indices strongly supported the correlated 8-syndrome structure in each of 30 societies. The results support use of the syndromes in diverse societies.

This study compared parents' ratings of behavioral and emotional problems on the "Child Behavior Checklist" (Achenbach, 1991; Achenbach & Rescorla, 2001) for general population samples of children ages 6 to 16 from 31 societies (N = 55,508). Effect sizes for society ranged from 0.03 to 0.14. Effect sizes for gender were less than or equal to 0.01, with girls generally scoring higher on Internalizing problems and boys generally scoring higher on Externalizing problems. Effect sizes for age were less than or equal to 0.01 and varied across types of problems. Total Problems scores for 19 of 31 societies were within 1 "SD" of the overall mean of 22.5. Bisociety correlations for mean item scores averaged 0.74. The findings indicate that parents' reports of children's problems were similar in many ways across highly diverse societies. Nonetheless, effect sizes for society were larger than those for gender and age, indicating the need to take account of multicultural variations in parents' reports of children's problems.

Standardized assessment instruments developed in one society are often used in other societies. However, it is important to determine empirically how assessment instruments developed in one society function in others. The present study tested the fit of the Teacher's Report Form syndrome structures in 20 diverse societies using data for 30,030 6- to 15-year-old students from Asia; Australia; the Caribbean; eastern, western, southern, and northern Europe; and the Middle East. A correlated seven-syndrome model and a hierarchical Attention Problems model were tested separately in each of the 20 societies via confirmatory factor analyses. The results supported the fit of the models in the tested societies. (Contains 5 tables and 2 figures.)

This study compared teachers' ratings of behavioral and emotional problems on the Teacher's Report Form for general population samples in 21 countries (N = 30,957). Correlations between internal consistency coefficients in different countries averaged 0.90. Effects of country on scale scores ranged from 3% to 13%. Gender effects ranged from less than 1% to 5%, and age effects were all less than 1%. With great consistency across countries, scores were higher for boys than for girls on eight scales: Total Problems; Externalizing; the Attention Problems, Rule-Breaking Behavior, and Aggressive Behavior syndromes; and "Diagnostic and Statistical Manual" (DSM)-oriented Attention Deficit Hyperactivity Problems, Oppositional Defiant Problems, and Conduct Problems. Correlations between mean item ratings in different countries averaged 0.74. Teacher's Report Form results were thus similar across 21 very diverse countries, despite differences across these countries in school systems, models of pedagogy, and curricula. (Contains 2 figures and 4 tables.)

In this study, the authors compared ratings of behavioral and emotional problems and positive qualities on the Youth Self-Report (T. M. Achenbach & L. A. Rescoda, 2001) by adolescents in general population samples from 24 countries (N = 27,206). For problem scales, country effect sizes (ESs) ranged from 3% to 9%, whereas those for gender and age ranged from less than 1% to 2%. Scores were significantly higher for girls than for boys on Internalizing Problems and significantly higher for boys than for girls on Externalizing Problems. Bicountry correlations for mean problem item scores averaged .69. For Total Problems, 17 of 24 countries scored within one standard deviation of the overall mean of 35.3. In the 19 countries for which parent ratings were also available, the mean of 20.5 for parent ratings was far lower than the self-report mean of 34.0 in the same 19 countries (d = 2.5). Results indicate considerable consistency across 24 countries in adolescents' self-reported problems but less consistency for positive qualities.

Introduction: The passive sentence structure is one of the most interesting syntactic structures on language development. Studies in some languages have indicated that comprehension of this syntactic structure takes place late in the language acquisition process. Therefore, the purpose of this study is to investigate the comprehension of active and passive structures in 48-59- and 60-71-month-old Persian-speaking children. Materials and Methods: 100 children aged 48-71 months (38 children aged 48-59 months and 62 children aged 60-71 months) participated in this study from seven different kindergartens and three preschools. Five active sentences and four passive sentences were uttered, and the children were asked to look at one of the four pictures in front of them and choose the correct one. After recording the replies, comprehension scores were compared between both age groups and both gender using independent t-test. In the end, the percentages of correct and wrong answers were analyzed. Results: There was a significant difference between the comprehension of active sentences by the children in both age groups (P < 0.050). Children aged 60-71 months scored higher. There were no significant differences between the comprehension of passive sentences between the two age groups (P > 0.050). Furthermore, there were no significant differences between the two genders in comprehension of active or passive sentences. Conclusion: Based on the findings of this study, it appears that Persian-speaking children aged 48-71 months have a better comprehension of active sentences compared to passive sentences. Furthermore, despite the improvement in the comprehension of active sentences from 48 months to 71 months, no noticeable change occurred in the comprehension of passive structures.

ObjectiveMethodsResultsConclusionsAlthough the significance of the general factor of psychopathology (p) is being increasingly recognized, it remains unclear how to best operationalize and measure p. To test variations in the operationalizations of p and make practical recommendations for its assessment, we compared p-factor scores derived from four models.We compared p scores derived from principal axis (Model 1), hierarchical factor (Model 2), and bifactor (Model 3) analyses, plus a Total Problem score (sum of unit-weighted ratings of all problem items; Model 4) for parent- and self-rated youth psychopathology from 24 societies. Separately for each sample, we fitted the models to parent-ratings on the Child Behavior Checklist for Ages 6–18 (CBCL/6–18) and self-ratings on the Youth Self-Report (YSR) for 25,643 11–18-year-olds. Separately for each sample, we computed correlations between p-scores obtained for each pair of models, cross-informant correlations between p-scores for each model, and Q-correlations between mean item x p-score correlations for each pair of models.Results were similar for all models, as indicated by correlations of .973–.994 between p-scores for Models 1–4, plus similar cross-informant correlations between CBCL/6–18 and YSR Model 1–4 p-scores. Item x p correlations had similar rank orders between Models 1–4, as indicated by Q correlations of .957–.993.The similar results obtained for Models 1–4 argue for using the simplest model – the unit-weighted Total Problem score – to measure p for clinical and research assessment of youth psychopathology. Practical methods for measuring p may advance the field toward transdiagnostic patterns of problems. [ABSTRACT FROM AUTHOR]

Objective: Although the significance of the general factor of psychopathology ( p) is being increasingly recognized, it remains unclear how to best operationalize and measure p . To test variations in the operationalizations of p and make practical recommendations for its assessment, we compared p -factor scores derived from four models., Methods: We compared p scores derived from principal axis (Model 1), hierarchical factor (Model 2), and bifactor (Model 3) analyses, plus a Total Problem score (sum of unit-weighted ratings of all problem items; Model 4) for parent- and self-rated youth psychopathology from 24 societies. Separately for each sample, we fitted the models to parent-ratings on the Child Behavior Checklist for Ages 6-18 (CBCL/6-18) and self-ratings on the Youth Self-Report (YSR) for 25,643 11-18-year-olds. Separately for each sample, we computed correlations between p- scores obtained for each pair of models, cross-informant correlations between p -scores for each model, and Q -correlations between mean item x p -score correlations for each pair of models., Results: Results were similar for all models, as indicated by correlations of .973-.994 between p -scores for Models 1-4, plus similar cross-informant correlations between CBCL/6-18 and YSR Model 1-4 p -scores. Item x p correlations had similar rank orders between Models 1-4, as indicated by Q correlations of .957-.993., Conclusions: The similar results obtained for Models 1-4 argue for using the simplest model - the unit-weighted Total Problem score - to measure p for clinical and research assessment of youth psychopathology. Practical methods for measuring p may advance the field toward transdiagnostic patterns of problems.

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.
