Percentile curves for Brazilian children evaluated with the Bruininks-Oseretsky Test of Motor Proficiency, 2nd edition / Curvas percentílicas para crianças brasileiras avaliadas pelo Teste de Proficiência Motora Bruininks-Oseretsky, 2ª edição

Abstract This study aimed to (1) create percentile curves and norms for the eight subtests of the Bruininks-Oseretsky Test of Motor Proficiency, 2nd edition (BOT-2) for 6- to 10-year-old Brazilian children and to (2) compare them to the values of the original test manual. To that, we tested a sample of 931 Brazilian children (477 girls, 454 boys) with ages between 6 to 10 with the BOT-2 assessment. The LMS method was used to generate the percentile curves and normative values, with the LMSchartmaker Pro software version 2.54. Results demonstrate that girls had significantly higher scores for the fine motor precision, fine motor integration, manual dexterity and balance subtests, while boys had significantly higher scores on upper-limb coordination, running speed and agility, and the strength subtests. The findings also indicated higher values for the Brazilian group in the subtests of bilateral coordination, running speed and agility, balance, and upper-limb coordination when compared to the North American normative sample. The percentile curves illustrate the increase in motor proficiency levels as age increases, with different trajectories for each subtest. Future studies should continue the investigation of cultural norms and appropriate assessments for the Brazilian population. Here, the creation of percentile curves and norms that are better suited for the Brazilian population can significantly help with assessment and intervention for motor development in distinct settings and with typical and atypical school-age children.

Resumo Este estudo objetivou (1) criar curvas e normas percentílicas para os oito subtestes do Teste de Proficiência Motora Bruininks-Oseretsky, 2ª edição (BOT-2) para crianças brasileiras de 6 a 10 anos e compará-las com os valores do manual de teste original. Para tanto, testamos uma amostra de 931 crianças brasileiras (477 meninas, 454 meninos) com idades entre 6 a 10 anos com a avaliação do BOT-2. O método LMS foi usado para gerar as curvas de percentil e valores normativos, utilizando o software LMSchartmaker Pro versão 2.54. Os resultados demonstram que as meninas tiveram escores significativamente mais altos nos subtestes de precisão motora fina, integração motora fina, destreza manual e equilíbrio, enquanto os meninos tiveram escores significativamente mais altos nos subtestes de coordenação de membros superiores, velocidade de corrida e agilidade e força. Os resultados também indicaram valores mais elevados para o grupo brasileiro nos subtestes de coordenação bilateral, corrida de velocidade e agilidade, equilíbrio e coordenação dos membros superiores quando comparados com a amostra normativa norte-americana. As curvas percentílicas ilustram o aumento nos níveis de proficiência motora à medida que a idade aumenta, com diferentes trajetórias para cada subteste. Estudos futuros devem continuar a investigação de normas culturais e avaliações apropriadas para a população brasileira. Neste estudo, a criação de curvas e normas percentílicas mais adequadas para a população brasileira pode ajudar significativamente na avaliação e intervenção para o desenvolvimento motor em diferentes contextos e com crianças em idade escolar típicas e atípicas.

Abstract In urgency and emergency services, the bicycle is the second means of transportation more widely used by the victims at the time of the accident. However, aspects associated with major and minor accidents are poorly understood. The aim was to develop an instrument and test its reproducibility, in order to evaluate behavioral and environmental aspects related to cyclist safety. The instrument was based on footage taken through a camera attached to the cyclist helmet and from a review of literature. Take part in the study academics that used the bicycle to travel at least once a week. Participants were instructed to indicate any safety-critical events on their way and situations of minor gravity based on the perception of real imminence of an accident. In order to identify aspects related to cyclist safety, the routes were divided in periods of 30 seconds. In order to test inter-rater reproducibility, two researchers received theoretical-practical training and performed the instrument in a sample of 100 periods. In order to evaluate the intra-rater reproducibility, one of the evaluators performed a second application after 07 days. The reproducibility of the categorical variables of the instrument were tested through general agreement and Kappa index. For the variables with continuous measuring range, the Intraclass Correlation Coefficient (ICC) was used. The percentage agreement varied between 88-100% and the Kappa values varied ​​between 0.76-1.00. The ICC values ​​ranged from 0.96-0.99. The developed instrument presents adequate reproducibility for use in research to evaluate the cyclist safety in urban contexts.

Abstract Objective To evaluate the construct validity and model-based reliability of general and specific contributions of the subscales of the Movement Assessment Battery for Children-2 (MABC-2) and Bruininks-Oseretsky Test of Motor Proficiency-2 (BOT-2) when evaluating motor skills across a range of psychiatric disorders. Methods Confirmatory factor analysis (CFA) and bifactor analysis were conducted on BOT-2 data from 187 elementary school students (grades 1 to 6) (mean age: 113 ± 20 months; boys: n = 117, 62.56%) and on MABC-2 data from 127 elementary school students (grade 1) (mean age: 76 ± 2 months; boys: n = 58, 45.67%). Results The results of the CFA fit the data for multidimensionality for the BOT-2 and presented poor fit indices for the MABC-2. For both tests, the bifactor model showed that the reliability of the subscales was poor. Conclusions The BOT-2 exhibited factorial validity with a multidimensional structure among the current samples, but the MABC-2 showed poor fit indices, insufficient to confirm its multidimensional structure. For both tests, most of the reliable variance came from a general motor factor (M-factor), therefore the scoring and reporting of subscale scores were not justified for both tests.

Resumo Objetivo Avaliar a validade de construto e a confiabilidade das subescalas do Movement Assessment Battery for Children-2 (MABC-2) e do Bruininks-Oseretsky Test of Motor Proficiency-2 (BOT-2) com base em modelos das contribuições gerais e específicas ao avaliar habilidades motoras em transtornos psiquiátricos. Métodos Foram realizadas análise fatorial confirmatória (AFC) e análise bifatorial em dados de 187 escolares do primeiro ao sexto ano do ensino fundamental (idade média: 113 ± 20 meses; meninos: n = 117, 62,56%) que foram avaliados com o BOT-2, e em dados de 127 escolares do primeiro ano do ensino fundamental (idade média: 76 ± 2 meses; meninos: n = 58, 45,67%) avaliados com o MABC-2. Resultados Os resultados da AFC apresentaram índices de ajuste satisfatórios de multidimensionalidade para o BOT-2 e apresentaram índices de ajuste insatisfatórios para o MABC-2. Para ambos os testes, o modelo bifatorial mostrou que a confiabilidade das subescalas era ruim. Conclusão O BOT-2 apresentou validade fatorial com uma estrutura multidimensional entre as amostras utilizadas, mas o MABC-2 apresentou índices de ajuste insatisfatórios, insuficientes para confirmar sua estrutura multidimensional. Para ambos os testes, a maior parte da variância confiável veio de um fator motor geral (fator-M), portanto, a pontuação e o relato dos escores das subescalas não se justificaram para ambos os testes.

Background familiar e desempenho escolar: uma abordagem com variáveis binárias a partir dos resultados do Saresp / Family background and school performance: an approach with binary variables from SARESP results / Fondo familiar y desempeño escolar: Un enfoque con variables binarias a partir de los resultados del SARESP

No presente estudo investiga-se o impacto de fatores externos à escola sobre a escolarização do indivíduo. Renda e escolaridade materna são consideradas para medir o efeito de aspectos familiares no desempenho em matemática do aluno. Para tanto, foram utilizados dados referentes à nota em matemática dos alunos da 3ª série do ensino médio e as respostas dos pais ao questionário socioeconômico, aplicado pelo Sistema de Avaliação do Rendimento Escolar do Estado de São Paulo (Saresp) na edição de 2013. São propostos modelos com variáveis binárias e obtidas estimativas para os parâmetros por meio do software SPSS. Os resultados mostram que rendas mais altas proporcionam melhores desempenhos educacionais, porém há restrições. O nível de escolaridade materna atua positivamente sobre o desempenho do aluno, mas está limitado ao nível adequado de proficiência.

This study researches the impact of outside school factors on individuals' schooling. Income and maternal schooling are taken into consideration when measuring the effect of familiar aspects on students' performance in Mathematics. Therefore, we used data referring to the Mathematics grade of students in 3rd year High School, and the answers provided by their parents for the socioeconomic questionnaire, applied by SARESP in its 2013 edition. Models with binary variables are proposed and estimates for parameters are obtained with SPSS. Results show that students from families with higher incomes indicate better educational performance, but there are restrictions. The level of maternal education positively influences student's performance, but is limited to appropriate proficiency levels.

Se proponen modelos con variables binarias y estimativos para los parámetros que se obtienen con el SPSS. Los resultados muestran que las rentas más altas proporcionan mejores resultados educativos, a pesar de lo cual hay restricciones: el nivel de escolaridad materna actúa positivamente sobre el desempeño del alumno, pero está limitado al nivel adecuado de competencia.

Testing the Validity of GRE Scores on Predicting Graduate Performance for National and International Engineering Students / Capacidad Predictiva de los Puntajes REG sobre el Rendimiento de Graduados Nacionales e Internacionales de Ingeniería

Abstract Numerous research studies have examined the validity of GRE scores in predicting graduate success, however, some limitations still exist. This study targeted graduate engineering programs and investigated the validity of GRE scores in predicting graduate engineering GPA (GGPA). In addition, the differences in the validity of GRE scores between American and international students and between masters' and doctoral students were compared. The GRE's incremental predictive ability over undergraduate GPA (UGPA) and TOEFL scores was examined. Data were obtained from 1083 students from the engineering programs in a large, comprehensive midwestern university. Results indicated that GRE was useful in forecasting GGPA of graduate engineering students. The GRE scores explained more criterion variance for American students than for international students, but statistically significant differences were only found when GRE-Quantitative predicted GGPA. The GRE-Verbal and GRE-Quantitative scores had different patterns in predicting graduate grades for master's and doctoral students. UGPA was found to be a very strong predictor, and TOEFL scores were significantly correlated with the criterion variables. GRE scores, however, were found to have significant incremental validity over UGPA and TOEFL scores. TOEFL scores were less able to make predictions.

Resumen Gran cantidad de estudios han examinado la validez de puntajes REG (Registro de Examinación de Graduados) como predictores del éxito de graduación, aunque aún existen algunas limitaciones. Este estudio se enfocó en programas de ingeniería y evaluó la validez de puntajes REG como predictor del GPA (Grade Point Average, Puntaje Promedio de Calificaciones) (GGPA). Adicionalmente, las diferencias en la validez de puntajes REG entre los estudiantes americanos e internacionales, así como los puntajes entre estudiantes de maestría y doctorado, fueron comparadas. La capacidad predictiva incremental del REG sobre el GPA de los estudiantes de pregrado (UGPA) y los puntajes TOEFL también fue evaluada. Se obtuvieron datos de 1083 estudiantes de programas de ingeniería de una universidad grande de la zona centro-oeste. Los resultados indicaron que el REG fue útil como predictor del GGPA de los estudiantes de ingeniería. Los puntajes REG explicaron mayor cantidad de varianza para estudiantes americanos que para estudiantes internacionales, aunque sólo se encontraron diferencias estadísticamente significativas cuando el REG cuantitativo predijo GGPA. Los puntajes REG verbal y REG cuantitativo presentaron puntajes diferentes al predecir calificaciones de los graduados de maestría y doctorado. El puntaje UPGA resultó ser un buen predictor, y los puntajes del TOEFL estuvieron correlacionados significativamente con las variables de criterio. Los puntajes REG, sin embargo, resultaron tener validez incremental significativa por encime de los puntajes UGPA y TOEFL. Los puntajes TOEFL fueron menos capaces de hacer predicciones.
