<h3>Research Objectives</h3> To investigate the professional self-perception of nurses in Mongolia for the first time and to determine if an educational intervention would improve their professional self-perception. <h3>Design</h3> Longitudinal Panel Study of nurses with four waves of data: pre-intervention, post-intervention, three-month post-intervention, and six-month post-intervention. This study focuses on the pre- intervention and post-intervention data. Analysis to examine change scores was completed using descriptive statistics, correlation, t-test, gamma, and ANOVA in Stata. <h3>Setting</h3> The setting was a privately owned hospital in Ulaan Bataar, Mongolia, the only Joint Commission International Accredited hospital in Mongolia via collaboration with Nurses Heart to Heart. <h3>Participants</h3> 104 nurses attended the educational intervention and were eligible with 67 choosing to be participants. Eligibility requirements included currently working as a nurse in a hospital and attend the educational intervention. <h3>Interventions</h3> The intervention was a 4-hour class focused on the care of patients undergoing procedures in the cardiac catheterization lab including patient safety, procedures in catheterization labs, and introducing a clinical pathway for the care of cardiac patients. <h3>Main Outcome Measures</h3> NPVS-3 (Nursing Professional Values Scale-3) both at pre-intervention and post-intervention. <h3>Results</h3> There are different patterns of change for nurses' professional self-perception across a myriad of contexts including demographics (gender, age, marital status, nurse in family), nursing training (education, career choice), and career as nurse (years in profession, role, and membership in professional nursing organization). Of note for gender, nurse in family, and marital status, we see both significant and substantive differences in professional self-perception after participating in our educational intervention. <h3>Conclusions</h3> Nurses in Mongolia have a high level of professional self-perception. Educational interventions for nurses in Mongolia are effective not only for skill building but also for improving nurses' professional self-perception. <h3>Author(s) Disclosures</h3> None.
