A set of questionnaires was developed which consist of three sections; demographic profile of respondent, work nature and discomfort survey and worker satisfaction on the usability of the manual handling devices. The content of the questionnaire was derived through extend literature reviews and expert’s opinions. A pilot study was conducted at four manufacturing companies in their warehouse’s operation. The reliability and validity of the instrument were determined through Cronbach’s Alpha, face validity and content validity. Cronbach’s Alpha values for each section of the questionnaire range from 0.937 and 0.961 while the value for Cronbach’s Alpha for all 35 standardized items is 0.921. The finding shows that the survey instrument has face and content validity at acceptable level. In conclusion, finding indicated that this instrument had acceptable and adequate reliability and validity to meet its objectives.
