Development and psychometric evaluation of the transcultural self-efficacy tool: a synthesis of findings.

The initial and ongoing assessment of students' self-efficacy perceptions (confidence) concerning culture care of diverse individuals is a valuable component in transcultural nursing education. The Transcultural Self-Efficacy Tool (TSET) was designed as a diagnostic tool to measure and evaluate students' transcultural self-efficacy perceptions for performing general transcultural nursing skills among diverse client populations. This article summarizes the steps in the TSET's development and evaluation, synthesizes reliability and validity findings from a series of psychometric investigations, and discusses future research and educational applications in transcultural nursing using the TSET.
