Need of Study: To design questionnaire for ergonomic evaluation and its cultural adaptation for traditional small scale industries
Methodology: Questionnaire development for ergonomic evaluation was done under the subtitle of personal information, work information, general health information, occupational problem assessment, pain assessment, knowledge of ergonomics. Two steps were proceeded: 1) cultural adaptation was done on general population (100) and (50) handicraft workers of different NGOs of Ahmedabad. 2) Face validity and content validity of questionnaire was assessed. 3) Intrarater and interrater reliability was assessed.
Results: Cronbach’s alpha was calculated for internal consistency. Its value was found was >0.9.
Conclusion: A cross-culturally validated questionnaire of Ergonomic evaluation cannot just help ensure an accurate evaluation of ergonomics, but is also a valuable asset for future comparison and evaluation of MSD and ergonomic evaluation across the world.
