Background and Objective: It is a widely held belief that the physical workplace environment exerts a profound effect on the health and performance of office employees. The assessment of administrative working environment can pave the way for the enhancement of ergonomic conditions of workplace environment. With this background in mind, the present study aimed to design a valid and psychometrically evaluated questionnaire for the assessment of administrative work environment.
Materials and Methods: Based on the theoretical foundations of ergonomics and the assessment of administrative work environment, a 22-item questionnaire for the evaluation of administrative workplace environment was designed. The face validity was evaluated by four experts and the content validity of the questionnaire (queries on necessity, relevance, clarity, and simplicity) was evaluated by 20 experts using the quantitative method (CVR and CVI). Thereafter, the questionnaire was administered to a total number of 203 employees of Iranian Gas Engineering and Development Company. Structural validity and reliability of the questionnaire were assessed by Cronbach's alpha coefficient using SPSSsoftware (version 24), and confirmatory factor analysis was performed in AMOS software (version 24) evaluating AVE and CR indices.
Results: Based on the results of content validity, 21 questions were approved and 1 question was rejected. The mean content validity ratio and the mean content validity index were reported as 0.73 and 0.94, respectively. In addition, the results of the structural validity and reliability of the questionnaire demonstrated that confirmatory factor analysis fit indices were acceptable; moreover, Cronbach's alpha coefficient for the whole questionnaire was measured at 0.882 and AVE and CR indices were estimated at 0.57 and 0.96, respectively.
Conclusion: As evidenced by the obtained results, the newly developed 21-item questionnaire for administrative workplace environment assessment enjoys an appropriate validity and reliability to evaluate the conditions of the administrative workplace environment concerning ergonomy (engineering psychology dimension), and can be administered as an effective tool in related research.
