Social support and factors associated with self‐efficacy among acute‐care nurse practitioners

Aims and objectives To investigate the relationship of nurse practitioners’ social support as well as other factors associated with perceived self‐efficacy. Background There is a growing demand for nurse practitioners in Taiwan, for whom self‐perceived efficacy is associated with performance. Nevertheless, research on the self‐efficacy and social support of nurse practitioners is limited. Design This is a cross‐sectional survey study. Methods Questionnaires were distributed to nurse practitioners in seven hospitals in northern Taiwan from May 2015 to March 2016. In total, data from 335 (78% return rate) certified nurse practitioners were analysed. Social support was measured by the Multidimensional Scale of Perceived Social Support (MSPSS) and the Job Content Questionnaire (JCQ), and perceived self‐efficacy was measured by the General Self‐Efficacy Scale (GSE). Data were analysed by ANOVAs with post hoc test and multiple linear regression. Results The mean score for self‐efficacy was 27.60 ± 6.17. Support scores were 11.574 ± 2.37 for supervisors, 12.795 ± 1.92 for coworkers and 64.07 ± 10.16 for family, friends and significant others. nurse practitioners in the high monthly salary group had significantly higher self‐efficacy than nurse practitioners in the medium and low monthly salary group ( F  =   8.99; p  <   .01). Social support from coworkers (β   = 0.18, p  <   .01) and family, friends and significant others (β   = 0.15, p  <   .01) and a higher monthly salary were significant factors. Conclusions The self‐efficacy of nurse practitioners in hospitals in Taiwan is insufficient. Monthly salary and levels of social support were found to contribute to nurse practitioners’ self‐efficacy. Thus, to enhance nurse practitioners’ self‐efficacy and work performance, nursing leaders should address these issues. Relevance to clinical practice The findings inform hospital administrators to be aware of the importance of salary in relation to nurse practitioners’ perceptions of social support and self‐efficacy.
