The Hungarian Adaptation, Validity and Reliability of the Questionnaire "Health Questionnaire on Back Care Knowledge in Daily Life Physical Activities for Adolescent Students" Examining the Back Care Knowledge and Spine Disease Prevention

Abstract

Background: There is a small number of questionnaires for children in the international literature that assess back care knowledge and spine disease prevention. A back care knowledge questionnaire in Hungarian for 14-17-year-old children is not yet available. This study aimed to translate and adapt the back care knowledge questionnaire published by Monfort et al. into the Hungarian language and to examine its reliability and validity in assessing the back care knowledge of 14-17-year-old children. Methods: This cross-sectional study included 253 (134 girls and 119 boys) adolescents, with a mean age of 14.84 (14-17) years. The questionnaire adaptation was performed according to Beaton's six-step principle. To test its internal consistency, the Kuder-Richardson 20 formula, containing binary variables, was used to assess the reliability of the questionnaire. The test-retest reliability was examined by the intraclass correlation coefficient (ICC). SPSS 27.0 software was used for data analysis, and the results were considered significant at p < 0.05. Results: The internal consistency measured by the Kuder-Richardson 20 coefficient examining the reliability of the questionnaire was 0.514. The test-retest reliability measured by intraclass correlation coefficients was 0.992 (0.985-0.996) p < 0.001. According to the Health Questionnaire on Back Care Knowledge and Spine Disease Prevention for 14-17-year-old children, the level of back care knowledge was 57.2%. Conclusions: The back care knowledge of Hungarian children is around 57.2%, which is lower than the data published in the international literature (60-70%). The Hungarian version of the questionnaire assessing the back care knowledge of 14-17-year-old children, the "Health Questionnaire on Back Care Knowledge and Spine Disease Prevention for 14-17 years old children (HEQBACK-14-17)", was found to be a suitable back care knowledge measuring tool among 14-17-year-olds; however, the development or adaptation of more measurement tools is needed for better understanding and more precise examination.
