Testing the Reliability and Validity of Self-Efficacy and Outcome Expectations of Restorative Care Performed by Nursing Assistants.

The primary aims of this study were to determine the reliability and validity of 2 measures: the Nursing Assistant Self-efficacy for Restorative Care Scale and the Nursing Assistant Outcome Expectations for Restorative Care Scale. This study included 386 nursing assistants from 8 nursing homes. The findings provide some support for the reliability and validity of these measures on the basis of Rasch analysis, confirmatory factor analysis, and convergent validity.
