Measuring nurses' self-concept

Little is known of nurses' self-concept in light of their professional identity or as working adults. This article explores the development and rigorous testing of a new self-concept instrument designed specifically for nurses. The new measure is based on the self-concept measurement theory of Shavelson, Hubner, and Stanton. An expert panel was used to critique and aid refinement of the measure. The dimensions of nurses' self-concept were measured in six scales: General Nursing, Care, Staff Relations, Communication, Knowledge, and Leadership. Two groups participated in this study: Group 1 consisted of nursing students prior to graduation (n = 506) and Group 2 consisted of randomly selected, experienced, working nurses (n = 528). A series of exploratory and confirmatory factor analyses were conducted to test the fit of a priori models. The results indicate that all scales possess good construct validity and a satisfactory fit with the data.
