One hundred different individuals were going to be used as subjects for the research. Univariate, bivariate, and multivariate analyses, in addition to the Chi square test, were utilized in order to analyze the data.According to the findings of the study, the p-value for the advocacy variable was found to be 0.000, while the values for the collaboration and communication variables were 0.001 and 0.002, respectively. This indicates that there is a connection between advocacy, teamwork, communication, and mentorship and the protection of gastroenteritis. The findings of the multivariate analysis revealed that the mentorship variable, which had an OR value of 35,174, was the most important factor in determining the outcomes of this research.Although there is a correlation between advocating, teamwork, communication, and mentorship and the protection of gastroenteritis, the findings of a multivariate analysis indicate that mentoring is the most important component.]]>
