Abstract
Background and Objectives: Work is essential in the lives of men and women; Although various scales for measuring the Physical exposure of most type of workers like commuter and aeromechanics and many more have already been developed in previous studies, a scale for the teaching staff particular to teachers has yet to be developed, also there is dearth of studies that have revealed its importance in the musculoskeletal disease. The purpose of this study was to develop a scale to measure the physical exposure in percentile form for teachers that are exposed during their normal teaching period that may lead to further musculoskeletal problems and to confirm its validity and reliability.
Design: An exploratory qualitative research study.
Methods: The developed scale was given to two trained interviewer to interview 500 school teachers who voluntarily participated in the present study and returned valid responses for test–retest reliability.
Results: Over all inter rater reliability was excellent for the teacher’s physical exposure grading in percentile scale, i.e. =0.716 (95% confidence interval 0.95 to 0.98)
Conclusion: The teacher’s physical exposure grading in percentile scale (TPEGP) Scale is composed of 2 subscales measured from a total of 10 factors. The validity and reliability of the TPEGP Scale was supported by the statistical analyses.
Keywords: Teachers Physical Exposure grading percentile scale (TPEGP), musculoskeletal diseases (MSD).
