The data on under-reporting MAE in Middle East Area is limited. Aim: The study intended to estimate the percentage of fear factor and explore the perception of nursing professionals regarding the reason for the occurrence and underreporting of MAE. Design: A cross-sectional design was utilized to conduct the current study. Place and Duration of Study: The study was conducted in eight hospitals working under Public health sector of Qatar between August and September 2016 Methodology: The data were collected with a purposive sample of 487 clinical nurses employed by the public health sector of Qatar who responded to a pre-designed online questionnaire. Results: The perceived prevalence of fear factor in non-reporting MAE was 23.45%, 95% confidence interval (C.I).: 16% to 33%. The single factor confirmatory factor analysis (CFA) model explained 65% of the variance in the fear factor of nonreporting of medication administration errors. The highest mean score in the subscale of reasons for non-reporting of MAEs includes fear (mean 0.652±1.671) and administrative responses (mean 0.304±1.466), and reporting processes (mean - 0.505±1.669), whereas disagreement over hospital definition (mean -1.158±1.528) of error was the least significant reason for nonreporting of MAE by the clinical nurses.
