Portuguese results with the EUA results and other countries that get the same structure. Furthermore, this structure has a less number of items, getting a more parsimonious model.

A limitation of the study is the low response rate; however, it is not unusual for an open population study once it was Web-only administrated, although we have identified ways to

Another limitation of the study was the number of missing values. It reduced the representativeness of the sample and can therefore distort inferences about the population. In future studies, the results will be compared using imputation methods on missing values and the

A strength of this study is the statistical method used, particularly in exploratory factor analysis and confirmatory factor analysis, since they are the most appropriate to the data type of this study, where bias was reduced. The majority of the studies on the context of this study

As it is well known in Portugal, the Directory of Health has been doing patient safety culture assessment every 2 years since 2014, which allows all health units to enhance patient safety.

The Portuguese version of the MOSPSC resulted in nine composites with good reliability and construct validity, where the structure differs from the original by removing one composite. In further studies, it will be performed longitudinal studies to evaluate the impact of patient

Patient safety culture assessment is of a vital importance for all levels of care. In Portugal, we are caring out this assessment every 2 years, which allows institutions to identify patient safety culture status in primary care, and it is also seen as an intervention to raise staff awareness about patient safety issues and a mechanism to evaluate the impact of patient safety improvement initiatives. This assessment also allows primary care institutions to compare their patient safety culture survey results with others and is a way to track changes in patient safety culture
