Abstract
This study developed a scale for assessing domestic university students' self-perception of their interdisciplinary integration-based core competencies in providing maternal-infant services. The scale was used for evaluating the effectiveness of interdisciplinary maternal-infant services curriculum. Two expert surveys were conducted to define the interdisciplinary integration-based core competencies in providing maternal-infant services and the draft version for the ＂Interdisciplinary Integration-based Core Competencies Scale for Maternal-Infant Services＂ (IICC-MIS scale) was developed. Two tests were then administered, after which the exploratory factor analysis and confirmatory analysis were performed to understand the reliability and validity of the scale as well as the goodness of fit between the theoretical model and the observed data. The findings showed that interdisciplinary integration-based competencies consisted of five core competencies, which were ＂communication,＂ ＂reflection,＂ ＂implementation,＂ ＂field-based general knowledge and skills,＂ and ＂professional ethics.＂ A subscale was developed for each core competency and a total of 27 items were constructed. The Cronbach's α value of internal consistency of the subscales of this scale ranged from .865 to .939. The Cronbach's α value of the IICC-MIS scale was .948 and was able to explain 70.6 % of variances. The IICC-MIS scale was administered and the structural equation modeling (SEM) analysis showed that the goodness of fit between the theoretical model and the observed data was in a moderate fit. This study also proposed some suggestions for further research in assessing interdisciplinary core competencies.
