Abstract: (435 Views)
Background and Objectives: Changes in mental workload are related to performance and level of fatigue, stress, human error, and job dissatisfaction. Questionnaires are a simple, accessible, and valid tool for measuring mental workload, so the purpose of this study is to translate cultural adaptation, and evaluation of psychometric properties of the Carmen-Q mental workload questionnaire.
Methods: In this study, 296 people (100 women and 196 men) with an average age of 38.59 ± 7.61 years, working in industrial and administrative sectors in several centers in Saveh city, participated. The process of translation and cultural adaptation was carried out in accordance with the relevant guidelines and included the stages of forward and backward translation, synthesizing and preparing a final version, piloting and then final approval of the Persian version. Psychometric properties including face validity (simplicity and readability), content validity (through content validity index), convergent validity (through correlation with NASA-TLX questionnaire), and internal consistency (using Cronbach's alpha coefficient) were performed.
Results: The translation, cultural adaptation and face validity were done according to the related guidelines and some minor changes were applied in the text. The Content Validity Index values for each of the items and its total (0.914) were acceptable. Cronbach's alpha value was acceptable for all items (0.91) and for each subscale (above 0.8). Pearson's correlation coefficient showed a moderate to good relationship between Carmen-Q and NASA-TLX scales.
Conclusion: The Persian version of the Carmen-Q questionnaire is a valid and reliable tool for evaluating mental workload in Iranian society.
