Construct validation of the English version of Readiness for Interprofessional Learning Scale (RIPLS): Are Chinese...

Interprofessional education has been receiving attention as a result of research suggesting the benefits of interpersonal collaboration in healthcare. In Hong Kong, the implementation of the Interprofessional Team-based Learning programme provides implicit call to study the psychometric properties of Readiness for Interprofessional Learning Scale (RIPLS) to clarify if this is a valid measure when used in the Chinese undergraduate healthcare context. This study examines the psychometric properties of RIPLS involving predominantly Chinese undergraduate healthcare students in Hong Kong. Using within- and between-network approaches to construct validity, we investigated the applicability of English version of RIPLS among 469 predominantly Hong Kong Chinese students who have competence in the English language. These participants were from complementary health professional programmes: biomedical sciences, chinese medicine, medicine, nursing, and pharmacy, from two universities in Hong Kong. The within-network test results indicated that RIPLS had good internal consistency reliability. Results of the confirmatory factor analysis lend support to the overall factor structure of hypothesized four-factor solution although one item obtained non-significant factor loading. The between-network test also suggests that various subscales of RIPLS correlated systematically with theoretically relevant constructs: collective efficacy, team impact on quality of learning, and team impact on clinical reasoning ability. The RIPLS is a valid measure to estimate the Chinese undergraduate healthcare students' readiness to engage in interprofessional learning.
