Adeniran, Smith, Bhattacharya and XU (2013) conducted a research with an objective to study differences in mentorship function and self-efficacy between U.S educated nurses (UEN) and internationally educated nurses (IEN) along with differences in taking part in professional development and career advancement. It was hypothesized that IENs will be less likely to report mentorship functions and self-efficacy compared with UENs and IENs enroll in fewer activities related to professional development and have less career advancement than UENs. The sample consisted of 200 middle aged nurses with 55 in IEN group (mean = 42.4 years, SD = 10.3) and 145 in UEN group (mean=41 years, SD= 10.6). The measures employed in this research study were two sub-sectioned mentorship measure, new general self-efficacy scale developed applying Eden’s definition of general self-efficacy and a demographic questionnaire. The research design used was cross-sectional research design and descriptive survey design was utilized to collect the data using a web based survey. The data was analyzed on SPSS –PC 18.0. Independent sample t test and chi-square were used to assess the differences in mentorship function and career advancement between both groups. The results revealed that both groups did not differ significantly for the mentorship function of career advancement (p=.80) and psychosocial support (p=.90), but both groups were significantly different for role model (p=.02). Moreover, UENs were significantly different from IENs to enroll in degree program after getting licensed (p=.01) and they pursued more advanced academic degrees (p=.02).
