ABSTRACT
Abstract Aim: The purpose of this paper was to analyze the internal consistency of the Sport Motivation Scale-II (SMS-II) questionnaire based on three studies with sports practitioners in the Brazilian college context. Methods: All the three studies i) were carried out with students enrolled in higher education and engaged in sports training by their institution (n1 = 304; n2 = 441; n3 = 310); ii) used SMS-II as an instrument for data collection; iii) used the online procedure for data collection. The Confirmatory Factor Analysis was performed and Cronbach's Alpha (α), McDonald's Omega (Ω), and the correlation between items were used to assess internal consistency. Results: As potentialities, five dimensions of the SMS-II presented high values of internal reliability (α and Ω > 0.60). As a limitation, the dimension of introjected regulation showed low reliability (α and Ω < 0.40) in the three studies conducted by our group. The exclusion of item 16 enabled an increase in alpha, but without achieving satisfactory reliability in Study 1 (α = 0.46) and Study 2 (α = 0.31). In Study 3, the exclusion of item 7 improved the internal reliability of the dimension (α = 0.43) also without reaching satisfactory values of internal consistency. It was not possible to identify a problematic item, given that each item had a different influence in the three studies. Conclusion: We found good values of validity and internal consistency for the Brazilian version of the SMS-II. However, we suggest attention to the introjected regulation dimension when using the instrument in the Brazilian college context.

Este estudo de revisão sistemática teve como objetivo levantar as pesquisas que investigaram o efeito da atividade física realizada no ambiente escolar em crianças com Transtorno de Déficit de Atenção e Hiperatividade (TDAH). Quinze estudos reuniram os critérios de inclusão estipulados e foram divididos em dois grupos, tendo como base a observação do efeito da atividade física sobre os sintomas de TDAH considerando as adaptações agudas e crônicas. Os programas de atividade física empregados eram variados, como os exercícios respiratórios do programa de ioga e a prática de diferentes modalidades esportivas, individuais e coletivas. Os resultados dos estudos apontam para a melhora dos sintomas do TDAH, tanto nas pesquisas que analisaram os efeitos agudos quanto crônicos das intervenções. Conclui-se que há efeitos benéficos da atividade física nos sintomas de TDAH em crianças e jovens e ressalta-se o protagonismo da escola como um espaço possível para o desenvolvimento de diferentes estratégias de intervenção física com potencial efeito sobre o TDAH.
This systematic review aimed to investigate the effect of physical activity in the school setting in children with Attention Deficit Hyperactivity Disorder (ADHD). Fifteen studies met the stipulated inclusion criteria and were divided into two groups based on the observation of the effect of physical activity on the symptoms of ADHD considering the acute and chronic adaptations. The programs of physical activity employed were varied, such as the breathing exercises of the yoga program and the practice of different sports modalities, individual and collective. The results of the studies point to the improvement of the symptoms of ADHD, both in the studies that analyzed the effects of acute and chronic interventions. It is concluded that there are beneficial effects of physical activity on the symptoms of ADHD in children and youngsters, and emphasizes the role of the school as a possible space for the development of different strategies of physical intervention with potential effect on ADHD.
ABSTRACT
A síndrome de Prader Willi (SPW) é uma doença genética causada pela deleção de genes na região 15q11-13. Associa-se com deficiência intelectual e alterações neurocomportamentais de difícil manejo. O objetivo do estudo foi comparar os problemas de comportamento de dois grupos de crianças e adolescentes com SPW em função da possibilidade de acesso livre e de acesso restrito a alimentos no ambiente familiar. A amostra foi composta por 12 crianças e adolescentes com diagnóstico citogenético-molecular para SPW (seis em cada grupo) e suas respectivas mães. Das crianças e adolescentes foi registrado o peso corporal em Kg e junto às mães foi aplicado o Inventário de Comportamentos para Crianças e Adolescentes entre 6 e 18 anos (CBCL/6-18). Houve diferenças estatisticamente significativas entre os grupos em relação a problemas de ansiedade e depressão, violação de regras e desafio e oposição. O grupo de acesso restrito ao alimento apresentou maior número de problemas comportamentais...
Prader-Willi syndrome (PWS) is a genetic disorder caused by a deletion of genes in region 15q11-13. It is associated with intellectual disability and unwieldy neurobehavioral alterations. The aim of the study was to compare behavior problems of two groups of children and adolescents with PWS considering the possibility of free or restricted access to food at home. The sample was composed of 12 children and adolescents with cytogenetic-molecular diagnosis of SPW (6 in each group) and their mothers. Children and adolescents had their body weight recorded and the Child Behavior Checklist for ages 6-18 years old (CBCL/6-18) was answered by the mothers. The groups presented statistically significant differences related to problems of anxiety and depression, violation of rules and defiance and opposition. The group with restricted access to food presented more behavioral problems...
