Hence, although the findings from the individual studies were consistent, the likelihood for imprecision in measurement method and potential bias with regard to research design and sampling suggests that the quality of evidence for the association between workplace bullying and sleep problems can be ...
Notwithstanding the above limitations, our findings suggest that different experimental settings and diagnostic tools may have potential effects on study results, underlying the importance of taking these factors into consideration during research design. Fifth, our keyword focused mainly on internet ...
