Limitations

This was a cross-sectional study; thus it is not possible to identify the cause and effect of relationships among productivity, stress symptoms, and violent events. In addition, there was no measurement of the perceived severity of the violent event, and thus, no way to examine the relationship among severity, symptoms, and productivity. As is common with survey studies, the use of self-report data may be limited by errors due to the nurses' poor recall of violent events and their perception of post-event stress symptoms and productivity. Another potential limitation of the results is the response rate of 8% and the inability to compare the responses of the responders with the non-responders. A post hoc power analysis was conducted to determine if the study had an adequate sample size to perform the planned statistical analyses. Achieved power was 85% for workplace violence data with the sample size of 220 in addition to using a two-sided statistic, a small to medium effect size of 0.20, and an alpha level of 0.05. So, even though only 8% responded, the findings are still powerful.
