Although interprofessional education and collaborative practice have gained increasing attention over the past five decades, development of rigorous tools to assess related competencies is still in infancy. The purpose of this study was to develop an instrument to evaluate health professions students' self-efficacy in interprofessional collaborative competency and to assess the instrument's psychometric properties. We developed a new instrument based on the Interprofessional Education Collaborative's (IPEC) Core Competencies for Interprofessional Collaborative Practice. In a cross-sectional study design, 660 students from 11 health programmes at an urban university in the Midwest USA completed the Interprofessional Education Collaborative Competency Self Efficacy Tool (IPECC-SET). Rasch analysis evaluated the following: (1) functioning of the instrument; (2) fit of items within each subscale to a unidimensional construct; (3) person-response validity; (4) person-separation reliability; and (5) differential item functioning in relation to gender and ethnicity. After removing seven items with suboptimal fit, each subscale demonstrated high internal validity. Two items demonstrated differential item functioning (DIF) for "Gender" and none for "Race/Ethnicity." Our findings provide early evidence of IPECC-SET as a valid measure of self-efficacy for interprofessional competence for health professions students. Additional research is warranted to establish external validity of the new instrument by conducting studies across institutions.
尽管跨专业教育与协作实践在过去五十年中受到了越来越多的关注，但用于评估相关能力的严格工具仍处于发展初期。本研究的目的是开发一种工具，以评估健康专业学生在跨专业协作能力方面的自我效能感，并评估该工具的心理测量特性。我们基于跨专业教育协作组织（IPEC）的跨专业协作实践核心能力开发了一种新工具。在美国中西部一所城市大学的11个健康项目中，660名学生参与了一项横断面研究设计，完成了跨专业教育协作能力自我效能量表（IPECC-SET）。Rasch分析评估了以下内容：（1）工具的功能；（2）每个子量表中的项目与单维结构的拟合度；（3）个体反应效度；（4）个体区分信度；以及（5）与性别和种族相关的项目功能差异。在删除七个拟合度欠佳的项目后，每个子量表都显示出较高的内部效度。有两个项目在“性别”方面显示出项目功能差异（DIF），而在“种族/民族”方面没有。我们的研究结果为IPECC-SET作为健康专业学生跨专业能力自我效能感的有效测量工具提供了早期证据。有必要通过跨机构研究来确定这一新工具的外部效度，以开展更多研究。
