This pilot study aimed to determine the clarity, relevance, understanding and reliability of the Revised Individual Workload Perception Scale with a sample of Omani nurses. The study also explored use of incident reports to determine if underreporting of errors exists in Omani hospitals. The IWPS-R has been shown to be a valid and reliable tool to measure nurses' perceptions in relation to their workload and work environment in the USA, Europe and Asian countries. IWPS-R has not been used in any Arab country including Oman. Therefore, the validity and reliability of the scale needed to be tested with an Omani sample. This pilot study also assessed the use of incident reports to identify the number, types and causes of errors in Omani hospitals in anticipation of a subsequent study. This pilot study used a descriptive statistical design and the data were collected using IWPS-R and, incident reports submitted by one hospital unit. The sample included 28 nurses. Data were analyzed using SPSS version 24 was used for data analysis. Cronbach's alpha coefficient for the IWPS-R was .708. All but two IWPS-R subscales had coefficients above .50. Most of the nurses reported understanding the items of the IWPS-R. Only six incident reports were submitted by the unit over a 3-month period, suggesting underreporting of medical errors.IWPS-R was found to be a valid and moderately reliable instrument when used with a sample of Omani nurses on four of its six subscales. The results supported the use of the IWPS-R in Oman. The small number of incidents reported suggested underreporting of errors, which necessitated major changes in the design of the subsequent larger study.
