Abstract

AIM:

This study describes the development and validation of the Nursing Profession Self-Efficacy Scale.

BACKGROUND:

Self-efficacy can be useful in predicting performance, job satisfaction or well-being. In the nursing field, there is a shortage of studies on self-efficacy with regard to nurses' global confidence in coping ability across a range of everyday, challenging work situations.

METHODS:

To define the theoretical framework of nursing professional self-efficacy, two focus groups and a literature review were performed. An empirical study was then conducted to test validity and reliability. Face and content validity, construct validity, concurrent validity, internal consistency and test-retest reliability were examined. The content validity index was evaluated by 12 experts who suggested deleting 11 redundant items. The final developed tool was tested for construct analysis using a cross-validation approach, randomly splitting the overall sample of 917 nurses in two sub-groups.

FINDINGS:

The construct validity indicated two dimensions. The face and content validity were adequate. Test-retest reliability displayed a good stability, and internal consistency (Cronbach's α) was acceptable. Moreover, concurrent validity using the Generalized Self-Efficacy Scale was in line with the theoretical framework.

CONCLUSION:

The scale showed evidence of validity and reliability. The major limitation is the strong influence of the Italian context in the tool development.

IMPLICATIONS FOR NURSING AND HEALTH POLICY:

The Nursing Profession Self-Efficacy Scale could be a fruitful tool that facilitates the application of theories (i.e. social-cognitive theory) in the nursing field and even development of interventions. Furthermore, a measurement of self-efficacy could be used to predict nursing clinical performance.
