Abstract Objectives: There is a critical need to monitor the development of children around the world, and in Brazil, this need is substantial since there is a paucity of assessment tools. This study aimed to describe the design and provide evidence of reliability and validity for the short version of the Dimensional Inventory for Child Development Assessment (IDADI-short). Methods: A sample of 1,865 biological mothers of children aged 4-72 months (M = 34.8, SD = 20.20) completed the IDADI to assess Cognitive, socio-emotional, Expressive, and Receptive Language and Communication, Fine and Gross Motor, and Adaptive Behavior development. The psychometric properties of a total of 118 subscales of IDADI were obtained and the IDADI-short age-specific scores were correlated with the original inventory, and criteria variables such as neurodevelopment diagnosis, socioeconomic status, and sex. Results: Item Response Theory analysis, Cronbach’s Alpha, and McDonald’s Omega indicated excellent internal consistency and optimal participant discrimination after minor alterations. IDADI-short scores were strongly associated with the original inventory, with high sensibility and specificity precision for developmental delays. Significant associations with relevant criteria variables were also observed. Conclusion: Findings support the use of IDADI-short as a parental measure of young children’s development.

Resumo Diferentes aspectos do contexto socioeconômico podem afetar a inteligência. Este estudo investigou o desempenho intelectual de crianças de diferentes regiões de moradia e tipos de escola. As análises compararam crianças da periferia (n = 169) e da região central (n = 110) de Porto Alegre; e crianças de escola privada (n = 49) e pública (n = 61). A coleta de dados incluiu a Escala Wechsler Abreviada de Inteligência (WASI) e ficha sociodemográfica. Utilizou-se Análise de Covariância (entre grupos) e Análise de Variância para medidas repetidas (intragrupo). O grupo de periferia apresentou menor desempenho em todos os escores da WASI e, na comparação intragrupo, resultados mais baixos nas tarefas verbais - o que não ocorreu no grupo da região central. Crianças de escolas públicas e privadas diferiram em todos os escores da WASI, mas apresentaram desempenho intragrupo semelhante.

Abstract Different aspects of the socioeconomic context can affect intelligence. This study investigated the intellectual performance of children from different places of residence and school types. The analyses compared children from the outskirts (n = 169) and the central region (n = 110) from Porto Alegre; and children from private (n = 49) and public (n = 61) schools. Data collection included the Wechsler Abbreviated Scale of Intelligence (WASI) and sociodemographic record. Analysis of covariance (between groups) and Analysis of Variance for repeated measures (within-group) were used. Children from the outskirts region showed poorer performance on all WASI scores and, in the within-group comparison, lower results on verbal tasks - which did not occur in the central region group. Children from public and private schools differed in all WASI scores but had a similar within-group performance.

Resumen Los diferentes aspectos del contexto socioeconómico pueden afectar la inteligencia. Este estudio investigó el desempeño intelectual de niños de diferentes regiones de vivienda y tipos de escuela. Se llevó a cabo una comparación de niños de la periferia (n = 169) y de la región central (n = 110) de Porto Alegre con niños de escuelas privadas (n = 49) y públicas (n = 61). Para recopilar los datos se utilizó la Escala de Inteligencia Abreviada de Wechsler (WASI) y la ficha sociodemográfica. Se aplicó el análisis de covarianza (entre grupos) y el análisis de varianza para medidas repetidas (intragrupo). El grupo de la periferia tuvo un desempeño más bajo en todos los puntajes de la WASI y presentó los resultados más bajos en las tareas verbales en la comparación intragrupo, lo que no ocurrió con el grupo de la región central. Los puntajes de los niños de las escuelas públicas y privadas fueron distintos en todos los puntajes de la WASI, pero en la comparación intragrupo tuvieron un rendimiento similar.

Abstract Intellectual disability (ID) is a developmental disorder characterized by deficits in intellectual functioning and adaptive behavior. The fifth edition of the Diagnostic and statistical manual of mental disorders (DSM-5) defines adaptive functioning as a severity measure of ID. The availability of tests in the international context to assess this construct has increased in recent years. In Brazil, however, non-systematic assessment of adaptive functioning, such as through observation and interviews, still predominates. The Escala de Funcionamento Adaptativo para Deficiencia Intelectual EFA-DI [Adaptive Functioning Scale for Intellectual Disabilities] is a new instrument developed in Brazil to assess the adaptive functioning of 7- to 15-year-old children and support the diagnosis of ID. This study's objectives were to investigate evidence of validity related to the EFA-DI's internal structure, criterion validity, and reliability. The psychometric analyses involved two statistical modeling types, confirmatory factor analysis (CFA) and item response theory analysis (IRT). These results highlight the EFA-DI scale's strong psychometric properties and support its use as a parental report measure of young children's adaptive functioning. Future studies will be conducted to develop norms of interpretation for the EFA-DI. This study is expected to contribute to the fields of psychological assessment and child development in Brazil.

Abstract This study aimed at the development of the Reading Subtest of the second edition of the School Performance Test (TDE-II). This study consisted in items selection, analysis by experts, and validation in which a sample of 661 students from the first to the ninth grades of Elementary School participated. The Subtest was divided in two versions: version A for students from the first to the fourth grades and version B for students from the fifth to ninth grades. Exploratory factor analysis indicated unidimensionality with one factor explaining 57% of the shared items variance for version A and 38% for version B. Item Response Theory analysis indicated appropriate levels of discrimination and difficulty for measuring the construct. Results suggest sources of validity in relation to test content, and internal structure. In terms of reliability, both versions covered the range of ability with high precision, thus suggesting that the Subtest presents good psychometric properties for reading evaluation.

Resumo O desenvolvimento infantil é complexo e compreende múltiplos domínios, como cognição, comunicação e linguagem, motricidade, socialização e desenvolvimento emocional. O objetivo desse artigo foi apresentar o processo de construção do Inventário Dimensional de Avaliação do Desenvolvimento Infantil (IDADI) e suas evidências de validade de conteúdo. O IDADI foi elaborado para avaliar o desenvolvimento infantil de zero até 72 meses de idade por meio do relato parental, abrangendo os domínios Cognitivo, Motricidade (Ampla e Fina), Comunicação e Linguagem (Receptiva e Expressiva), Socioemocional e Comportamento Adaptativo. O processo envolveu: fundamentação teórica; construção da versão preliminar; análise dos itens por juízes especialistas; análise semântica dos itens pela população-alvo; e estudo piloto. Partiu-se de um pool de 2.365 itens, chegando-se a uma versão de 524 após exclusões, modificações e inserções de itens. As etapas da construção determinaram mudanças em grande parte dos itens. Considera-se que esse processo garantiu a validade de conteúdo do instrumento. Espera-se que o IDADI contribua à área de avaliação do desenvolvimento infantil no Brasil, tanto no contexto da pesquisa como na clínica.

Abstract Child development is complex and includes multiple domains, such as cognition, communication and language, motor skills, socialization, and emotional development. The objective of this paper was to present the development process of the Dimensional Inventory of Child Development Assessment (IDADI) and evidence of its content validity. IDADI was conceived to assess child development of children from zero to 72 months of age through parental reports covering Cognitive, Motor (Gross and Fine), Communication and Language (Receptive and Expressive), Socioemotional and Adaptive Behavior domains. The development process involved: description of the theoretical foundation; development of the preliminary version of the instrument; expert item analysis; semantic analysis of the items by the target population; and a pilot study. The initial item pool had 2,365 items and the final version consisted of 524, after exclusions, modifications and additions. The stages of development led to changes in most of the items. This process is considered to have ensured IDADI’s content validity. Thus, it is believed that IDADI will contribute to child development assessment in Brazil in clinical and research contexts.

Las etapas de desarrollo determinaron cambios en la mayoría de los ítems. Se considera que este proceso ha asegurado la validez del contenido del IDADI. Esperamos que IDADI pueda contribuir a la evaluación del desarrollo infantil en Brasil en contextos clínicos y de investigación.

Abstract The Coping Health Inventory for Parents (CHIP) evaluates coping patterns of parents of chronically ill children and assesses different coping strategies using three subscales. This study aimed to translate and transculturally adapt the CHIP for a Brazilian sample and investigate the preliminary psychometrics of the scale. Rating scale Rasch analysis was performed on CHIP responses, and the psychometric performance of each of the three subscales was tested. Two hundred twenty parents of individuals with health problems participated in the study, answering a sociodemographic questionnaire—the Brazilian version of the CHIP—and Folkman and Lazarus’s coping questionnaire. All items exhibited good fit to the measurement model, although response categories were not used as intended and little variability on person parameter estimates was obtained. These preliminary results suggested that each construct being measured by the three subscales should be treated separately, corroborating the theoretical model of the original instrument. Suggestions to address the psychometric limitations of the instrument were made in order to improve measurement precision.

Abstract The School Achievement Test (Teste de Desempenho Escolar, TDE) has been widely used in clinical and educational contexts for the past 22 years. Arithmetic disorders are frequent among children and teenagers, requiring new and updated tasks to assess as accurately as possible school achievement. The last decade has witnessed a growing recognition of the need for significant changes in educational assessment practices. Evidence provided by item response theory (IRT) enabled the link of more detailed information improving assessment quality. The aim of this study was to develop a revised and completely updated version of the Arithmetic Subtest for the School Achievement Test-Second Edition (Teste de Desempenho Escolar-Segunda Edição, TDE-II). To this end, two studies were conducted. The first study focused on item and test construction, while the second study assessed the preliminary version of the instrument. The sample consisted of 302 students in grades 1 through 9 recruited from public and private schools. Factor analysis revealed two factors which explained 74 % of the variance in the data. Both dimensions were closely related to item complexity and difficulty. The subtest was therefore divided into two versions: one for students in grades 1 through 5 and the other for those in grades 6 through 9. Both versions were analyzed based on IRT models, which suggested that the items provided a comprehensive measure of the latent trait. The results provided satisfactory evidence of internal structure and reliability. Results indicated that the Arithmetic Subtest of the TDE-II has adequate psychometric properties for the assessment of arithmetic skills in primary education. Interpretation based on IRT analyses can be helpful for future studies about math education, discriminating even better between learning difficulty and typical groups, with the data to be the basis of math cognition stimulation programs.
