Development of Knowledge, Attitude, and Practices Questionnaire for Computer Workstation Ergonomic Behaviors among Senior High School and College Teachers in a Private University in the Philippines

The shift to a work-from-home set-up placed professionals, particularly those in the education sector, at risk for developing musculoskeletal disorders (MSKD). Targeting teachers’ knowledge, attitude, and practices (KAP) concerning computer workstation ergonomic behaviors (CWEB) is a way to reduce the risk. Still, there is currently a shortage of information about this strategy. The researchers conducted a pilot study to develop a KAP questionnaire to provide information about the risk factors for developing MSKD and KAP related to CWEB. The first draft was generated via literature review and was revised by six (6) experts through content validation. Thirty (30) teachers from the senior high school department and colleges of Lyceum of the Philippines University – Batangas answered the revised questionnaire. Five teachers and five experts performed face validation. Discriminant validity was analyzed using Pearson correlation. Internal consistency was analyzed using Cronbach’s alpha for attitude and Kuder-Richardson 20 formula (KR20) for knowledge and practices. Test-retest reliability was assessed using the intraclass correlation coefficient. Results from the validation process demonstrated adequate content, face, and construct validity. KR-20 values of knowledge (0.70) and practices (0.72), as well as Cronbach’s alpha coefficient of attitude (0.94) section, indicated acceptable tool reliability. The second draft of the questionnaire showed adequate psychometric properties in assessing KAP related to CWEB when used as a self-report tool. The questionnaire was further revised based on the appreciation of the results for improvement. Overall, this pilot study produced a valid and reliable tool with the potential for large-scale testing and implementation. This tool can facilitate future research exploring the risk factors and ergonomic behaviors of teachers, which can then be used as a guide in planning and designing interventions to lessen the risk of developing MSKD.
