ABSTRACT
Cognitive-based human errors have major contribution to performance and safety in working environment. This study designed to develop a measurement tool in order to evaluate this type of errors in the occupational settings. An Occupational Cognitive Failure Questionnaire [OCFQ] was developed. Content validity of the OCFQ was performed using a quantitative approach. Reliability of questionnaire was assessed by internal consistency and test-retest methods. A preliminary list of 35-items was prepared as a starting point. After evaluation of validity, five items were rejected. The new measurement instrument with 30-items was finally developed. The content validity index [CVI] for the final OCFQ was found acceptable [CVI=0.7]. Results show that final OCFQ was internally consistent [alpha=96] and intraclass correlation coefficients [ICC] was 0.99. Measurement of cognitive failure in the workplace requires a valid and reliable tool. In respect to probable outcomes of cognitive failures occurrence at work, the present study suggested that OCFQ would be a useful instrument for measurement of cognitive failure in the working environment
