Multivariate Outliers: A Conceptual and Practical Overview for the Nurse and Health Researcher

The use of Latent Profile Analyses to examine social dominance orientation as a predictor of peer-to-peer aggression among adolescents

Peer-to-peer aggression and bullying is a social phenomenon and is related to social structures in the school. In-group membership as well as construction of the other and differentiation from other potential groups is an important predictor of one's social identity. Social Dominance Orientation is an important addition to social identity theory as it examines both issues of social dominance and social egalitarianism and is related to out-group denigration. In this study, we examined whether social dominance theory (both the dominance and egalitarian forms) will add to the prediction of physical and relational aggression among adolescents. Using a bias-corrected 3-step approach, we used Latent Profile Analyses to examine the responses of 1617 Israeli adolescents on measures of social dominance and egalitarian orientation, salience of their social groups and moral disengagement. Based on the analysis, we identified four classes of respondents, which can be broken down into two distinct categories: high social dominance and moral disengagement and high social egalitarianism. We compared male and female adolescent respondents and group salience. We then compared the four latent profiles on the two distal variables of physical and relational peer-to-peer aggression. Findings have theoretical and applied relevance to further investigating issues of group dynamics and construction of the other as potential predictive factors in understanding peer-to-peer aggression and bullying.

Sensitivity Analysis: A Method to Promote Certainty and Transparency in Nursing and Health Research

Nursing and health researchers may be presented with uncertainty regarding the utilization or legitimacy of methodological or analytic decisions. Sensitivity analyses are purposed to gain insight and certainty about the validity of research findings reported. Reporting guidelines and health research methodologists have emphasized the importance of utilizing and reporting sensitivity analyses in clinical research. However, sensitivity analyses are underreported in nursing and health research. The aim of this methodological overview is to provide an introduction to the purpose, conduct, interpretation, and reporting of sensitivity analyses, using a series of simulated and contemporary case examples.

Occupational fatigue, individualized nursing care, and quality of nursing care among hospital nurses

PURPOSE

This study aimed to evaluate the relationships among nurse fatigue, individualized nursing care, and nurse-reported quality of care.

DESIGN

The study used a cross-sectional design. Data from 858 registered nurses providing bedside care in hospitals were collected between March and April 2021 in the United States.

METHODS

Participants completed a self-administered online survey, including the Occupational Fatigue Exhaustion Recovery scale, the Individualized Care Scale-Nurse version, and a single item assessing nursing care quality. Relationships among the study variables were examined using multiple linear and logistic regression models.

FINDINGS

Nurses' higher levels of acute fatigue were significantly associated with decreased perceptions of individualized nursing activities provided to patients on their last shifts, specifically related to personal life condition and decision-making control. Nurses' higher levels of chronic fatigue were significantly associated with decreased perception of individualized nursing activities provided to patients on their last shifts related to clinical condition, personal life condition, and decision-making control. Nurses with higher levels of acute or chronic fatigue, and who perceived their nursing care activities as less individualized were less likely to assess their quality of care as excellent.

CONCLUSION

These findings suggest that addressing hospital nurses' acute and chronic fatigue may contribute to promoting the delivery of individualized nursing care and in improving patients' quality of care.

CLINICAL RELEVANCE

Healthcare institutions are encouraged to regularly monitor and manage nurse fatigue to improve the delivery of individualized and quality nursing care to their patients.
