The Development of Chinese Version of Transcultural Nursing Self-Efficiency Scale: Using Rasch Model Analysis

Introduction: With the huge advances of globalization and urbanization, the nursing services in China are meeting the challenge of varied culture-specific needs in practices. Tools to measure transcultural sensitivity thus has great value in promoting transcultural nursing practices. Method: The Chinese version of Transcultural Nursing Self-Efficacy Scale (TSET-CV) was translated and validated with a sample of 2,346 nurses in China. Utilizing the analytical framework of the rating scale model, each item of the three subscales, namely the cognitive, practical, and effect subscale, was analyzed in terms of item analysis, item fitting, difficulty, reliability, item function, and validity. Results: The analysis suggested that 5-point Likert-type scale was more suitable than the 10-point Likert-type scale originally used. Item 27 and Item 79 showed deficient properties, which was deleted in the TSET-CV. The most accurate ranges measured by the TSET-CV matched the range of the distribution of the subjects’ ability. Discussion: Unlike the classical test theory, the rating scale model based on the Rasch’s model can provide sample-independent psychometric properties of items. The revised TSET-CV has great potential in diagnosing deficiency among nursing student in transcultural self-efficiency, which can promote the development of corresponding education strategies.
