NASA-TLX Questionnaire Adapted and Validated for Persian Speakers Across Occupations
A study has successfully translated, culturally adapted, and psychometrically evaluated the NASA-TLX (Task Load Index) questionnaire for use among Persian-speaking individuals. The NASA-TLX is a widely recognized tool used to measure perceived workload in various tasks and professions. This research aimed to ensure the questionnaire's accuracy and reliability when applied to a Persian-speaking population, considering potential linguistic and cultural nuances. The evaluation involved rigorous statistical analyses to confirm the instrument's validity and internal consistency. The findings indicate that the adapted Persian version of the NASA-TLX is a dependable measure of workload. This development is significant as it allows for more accurate and standardized assessments of job demands and stress levels within diverse occupational settings where Persian is spoken. Researchers and organizations can now utilize this validated tool to better understand and potentially mitigate factors contributing to occupational strain.
The successful adaptation and validation of the NASA-TLX for Persian speakers represent a crucial step in standardizing workload assessment across linguistic and cultural boundaries. This initiative addresses the critical need for culturally sensitive research tools, enabling more equitable comparisons of occupational stress and performance. By providing a reliable instrument, the study empowers organizations to identify systemic pressures on workers, fostering environments that prioritize well-being and efficiency. Future applications could involve longitudinal studies tracking workload trends and the impact of technological or organizational changes on Persian-speaking workforces, contributing to evidence-based policy development in the evolving global labor market.
