Consistency and reliability of the Brazilian Portuguese version of the Mini-Sleep Questionnaire in undergraduate students.

PURPOSE: Questionnaires are indispensable tools in epidemiologic studies and clinical surveys. Many questionnaires focusing on sleep disorders have been described in the literature. This cross-sectional study is aimed to assess the consistency and reliability of the Brazilian Portuguese Version of the Mini-Sleep Questionnaire (MSQ-BR). METHODS: Self-administered questionnaires were given to a sample of 1,108 undergraduate students. The variables collected were age, gender, socioeconomic level, and MSQ-BR scores. A subgroup of 53 students was randomly chosen to test the test-retest reliability of the instrument. Internal consistency of total MSQ-BR and its subscales (i.e., insomnia and hypersomnia) was evaluated using Cronbach's alpha coefficient. RESULTS: Our results showed good internal consistency of total MSQ-BR score, with a Cronbach's alpha value of 0.770. The insomnia subscale had an adequate internal consistency (Cronbach's alpha, 0.749). On the other hand, the hypersomnia subscale had moderate internal consistency (Cronbach's alpha, 0.624). The test-retest analysis showed good reliability of the instrument using Pearson's correlation coefficient. CONCLUSIONS: The MSQ-BR has adequate internal consistency and test-retest reliability. The MSQ-BR insomnia has adequate internal consistency for use as a separate application. However, the MSQ-BR hypersomnia demonstrated only moderate internal consistency for use as a separate application. Our intention was not to introduce modifications to the questionnaire, but to evaluate the reliability of total MSQ-BR and its subscales. Others studies are needed to assess the consistency of MSQ compared to other instruments.

O que os pacientes com acidente vascular encefálico sabem sobre sua doença? / What do the patients with stroke know about their disease?

Introdução: O acidente vascular encefálico (AVE) é uma das maiores causas de mortalidade e morbidade no Brasil e há pouco conhecimento sobre a doença entre a população, o que produz reflexos no tratamento e aumento da morbidade Objetivo: Investigar a percepção do paciente com acidente vascular encefálico (AVE) sobre sua doença. Metodologia: Foi conduzido um estudo qualitativo em pacientes em reabilitação por AVE. Foram realizadas entrevistas com roteiros semiestruturados contendo os seguintes tópicos: conhecimento dos fatores de risco e tratamento; percepção e reação no momento do início dos sintomas; e atitudes dos pacientes perante um novo quadro hipotético de AVE. Resultados: Apesar de alguns pacientes terem demonstrado conhecimento razoável sobre o que é AVE, alguns apresentaram total desconhecimento. Observou-se o desconhecimento da gravidade da doença na ocasião do AVE, resultando em demora na procura por auxílio médico. Falta de consciência sobre os fatores de risco e atitudes negativas dos familiares em relação aos sinais e sintomas também foram observadas. Conclusão: Este estudo demonstrou uma lacuna importante no conhecimento por parte dos pacientes realizando reabilitação para estas doenças, o que possivelmente contribui para a baixa adesão ao tratamento e à prevenção do AVE.

Introdução: Stroke is one of the major causes of mortality and morbidity in Brazil, but the knowledge about the disease is poor among the general population, which affects treatment adherence and increases morbidity. Aim: To investigate the perceptions of stroke patients of their disease. Methods: A qualitative study was conducted in patients recovering from stroke. Semi-structured interviews were carried out containing the following topics: knowledge of risk factors and treatment; perception and reaction at the onset of symptoms; and patient attitude toward a new hypothetical picture of stroke. Results: Although a few patients showed reasonable knowledge about what a stroke is, some showed utter lack of any knowledge. Unawareness of the severity of the disease at the onset of stroke was observed, resulting in delay to seek medical care. Lack of knowledge of risk factors and negative attitudes of family members regarding signs and symptoms were also observed. Conclusion: This study has demonstrated a significant lack of knowledge by patients in rehabilitation from stroke, which is likely to contribute to the poor adherence to treatment and prevention.
