Abstract: (12382 Views)
Background & objective: Proper lighting increases the productivity and efficiency of people in the workplace. This study aimed to translate and validate the office lighting survey questionnaire (OLS) to make it usable in Iran and to create a suitable tool for conducting research related to the qualitative study of workplace lighting.
Materials & Methods: The present study is an analytical study that was conducted to determine the validation of the Persian version of the OLS questionnaire on employees of one of the governmental offices in Kerman province. First, the Persian version of the questionnaire was prepared using the Backward-forward method and then the translated questionnaire was distributed among the 49 employees. CVI and CVR, and test-retest tests were used to measure validity and reliability respectively. Chi-square and Mann-Whitey tests in SPSS version 26 were also used to analyze the data. Chi-square and Mann-Whitey tests in SPSS version 26 were also used to analyze the data.
Results: In the validity analysis, Kappa's and Spearman's coefficients were used to analyze the agreement and correlation between the questions. Intra-class correlation coefficient in the reliability analysis was 0.949. It was found that there is a significant relationship between employees' job satisfaction with lighting and most questions of the OLS questionnaire.
Conclusion: The Persian version of the OLS questionnaire is a useful tool for assessing the quality of lighting in office environments that can be used as part of routine design and measurement programs for office environments and occupational care to prevent job dissatisfaction problems.
