Rating of perceived capacity: a proposal to predict adequate levels of physical activity in visually impaired individuals.

BACKGROUND: There are several instruments that are generally used to analyze levels of physical activity (PA) in people with visual impairment. However, few instruments are validated for this population. The purpose of this study was to compare the subjective and objective variables of PA and to propose the use of the Rating of Perceived Capacity (RPC) to evaluate the level of moderate to vigorous physical activity (MVPA) per day in this population. METHODS: Thirty-seven individuals with visual impairment participated in the study (19 blind without light perception and 18 low-vision). For the subjective physical activity evaluation, it was used the International Physical Activity Questionnaire Short Form (IPAQ-SF) and for the objective evaluation, it was used the ActiGraph GT3X+. RESULTS: Among the three analyzed (PA) intensities: moderate physical activity (MPA), vigorous physical activity (VPA) and MVPA, in VPA and MVPA was observed differences between the two methods (P=0.002 and P=0.011 respectively). Furthermore, the concordance between subjective and objective MVPA was not observed (ICC=0.239; P=0.176), and a greater variability of differences in MVPA between the two methods was observed by the Bland Altman scatter plot. However, positive correlation was found between the RPC and MVPA (P=0.470; P=0.003). In addition, in the Receiver Operating Characteristic (ROC) curve analysis, it was verified that values greater than 8 points in the RPC showed a predictive capacity for sufficient levels of objective MVPA (AUC=0.809, sensitivity =66.7, specificity =90.9, P≤0.001). CONCLUSIONS: We concluded that the MVPA per day obtained by IPAQ-SF did not show agreement for the objective MVPA in visually impaired individuals. On the other hand, RPC presented itself as an alternative, practical and accessible tool to predict adequate levels of MVPA per day in this population.

Translation and validation of the Pediatric Daytime Sleepiness Scale (PDSS) into Brazilian Portuguese / Tradução e validação da Pediatric Daytime Sleepiness Scale (PDSS) para o português do Brasil

Abstract Objective: The aim of this study was to translate and validate the Pediatric Daytime Sleepiness Scale (PDSS) into Brazilian Portuguese. Methods: The translation/validation process was carried out through translation, back translation, technical review, assessment of verbal comprehension/clarity of the scale by experts and a focus group, test–retest, and application of the tool. The reproducibility analysis was performed by applying the PDSS in test–retest; internal consistency was verified by applying the scale in 90 children and adolescents. Results: The mean score of the sum of PDSS questions was 15.6 (SD = 5.0) points. The PDSS showed appropriate indicators of content validation and clarity for the Brazilian Portuguese version. The internal consistency analysis showed a Cronbach's alpha of 0.784. The PDSS showed adequate reproducibility. The PDSS scores showed a significant and negative correlation with time spent in bed (r = −0.214; p = 0.023). Conclusion: The Brazilian Portuguese version of the PDSS shows satisfactory indicators of validity and can be applied in clinical practice and scientific research.

Resumo Objetivo: Traduzir e validar o Pediatric Daytime Sleepiness Scale (PDSS) para o português (Brasil). Método: O processo da tradução/validação deu-se por meio da tradução, retrotradução, revisão técnica, avaliação da compreensão verbal/clareza do questionário por especialistas e por grupo focal, teste-reteste e aplicação do instrumento. A análise de reprodutibilidade fez-se por meio da aplicação da PDSS em teste-reteste e a consistência interna pela aplicação da escala em 90 crianças e adolescentes. Resultados: A pontuação média verificada no somatório das questões da PDSS foi 15,6 (5) pontos. A PDSS apresentou adequados indicadores de validade de conteúdo e clareza de linguagem em português do Brasil. A análise da consistência interna identificou alfa de Cronbach de 0,784. A PDSS apresentou adequada reprodutibilidade. Os escores da PDSS apresentaram correlação negativa e significativa com o tempo na cama (r = -0,214; p = 0,023). Conclusões: A versão em português da PDSS apresenta satisfatórios indicadores de validade e pode ser aplicada na prática clínica e em pesquisas científicas.

[Elementary school teachers and their quality of life]. / O trabalho docente e a qualidade de vida dos professores na educação básica.

OBJECTIVES: Investigating some pertinent factors associated with elementary education teachers' quality of life working in the Brazilian city of Florianopolis and surrounding district. METHODS: 349 state and municipal school system elementary school teachers working in the city and its surrounding areas answered a questionnaire containing work-related questions and the WHO Quality of Life-BREF (WHOQOL-BREF) questionnaire. Descriptive statistics were used and the differences between means were analyzed, considering physical, psychological, social relationships and environmental domains. RESULTS: Teachers working more hours per week and in the state school system had lower quality of life indices in all domains investigated. Those having more years of service in the teaching profession had lower quality of life indexes regarding the physical (p=0.007) and social relationships (p<0.001) domains. Teachers occupying management/supervisory posts had higher quality of life scores in the environmental domain compared to classroom teachers. CONCLUSIONS: The hours worked seemed to be the main factor associated with lower quality of life scores in this sample of elementary school teachers.

Objetivos Investigar alguns fatores relacionados com a qualidade de vida de professores de educação básica do município de Florianópolis, SC, Brasil, considerando as características do trabalho docente. Métodos 349 professores das redes municipal e estadual de educação, que trabalhavam em escolas das diferentes regiões do município, responderam a um questionário com questões relacionadas ao trabalho e ao Whoqol-bref. Foram realizadas análises descritivas e testes de diferenças entre médias dos indicadores de qualidade de vida geral e dos domínios físico, psicológico, relações sociais e meio ambiente. Resultados Os professores com maior carga horária semanal e aqueles da rede estadual de ensino apresentaram menores índices de qualidade de vida em todos os domínios investigados. Professores com mais tempo de serviço no magistério apresentaram menores índices de qualidade de vida considerando o domínio físico (p=0,007) e relações sociais (p<0,001). Os professores em cargo de direção/supervisão apresentaram escores superiores de qualidade de vida no domínio meio ambiente em relação aos professores de sala de aula. Conclusões Em síntese a redução da carga horária parece ser o principal fator associado com menores índices de qualidade de vida na amostra.
