The study's purpose is evaluating the relationship between locus of control and selfesteem in relation to the registered nurse's experience and perception with lateral and vertical incivility. There is a lack of research concerning nurse-to-nurse incivility within the nursing profession. The hypothesis examined whether dynamics of locus of control and self-esteem could provide insight into the personality dynamics influencing incivility in the workplace. This non-experimental quantitative study used 2 self-evaluation tools and 1 demographic survey tool to collect data via Survey Monkey, a commercial data collection company. Participants were 65 randomly selected faculty (n = 36) and graduate students (n = 29) from schools of nursing in Southern California, all active practitioners. Descriptive statistics provided the demographic data and RNs' experience of incivility analysis. Inferential statistics, t-test, and Pearson's correlation analyzed the relationships between study variables. Study results indicated no significant negative relationship between RNs' perceived experience with lateral and vertical incivility, and RNs' level of self-esteem and locus of control. Participants indicated a greater than 80% experience with incivility in the work place either directed at the participant or towards a colleague. The study results will be of interest to health provider managers as a means of insight into the pervasiveness of incivility in the workforce. The study indicated the problem of professional incivility is widely encountered, it rules out the hypotheses that self-esteem and locus of control are related to the problem, and it encourages the need for further study as to the etiology and dynamics of the problem.
