The Brief Attitudes Survey for Interprofessional Collaborative Learning: The Design, Reliability, and Validation of a New Instrument.

This paper describes the development and validation of a new questionnaire designed to measure and investigate attitudes towards interprofessional education (IPE) among health professions students. After a thorough literature review and survey of prior instruments, we created an instrument built around a single construct domain: attitudes toward interprofessional collaborative learning. Through a rigorous design methodology rooted in behavior change theory and an iterative question development process, we launched the 11-item "Brief Attitudes Survey for Interprofessional Collaborative Learning" (BASIC-L). Implemented as part of a "toolbox" for assessing the progress of learners in IPE, the questionnaire was then administered to a large cohort of medical and nursing students. Its reliability, validity, and fit with our one-domain model were evaluated via thorough psychometric analysis, including computation of reliability coefficients and a Rasch analysis. These analyses indicate strong reliability, validity, and fit of the questions with our one-domain model. The analyses also included assessment for any sources of measurement error, which were not significant. The BASIC-L appears to be a useful, valid, and reliable instrument for the assessment of attitudes toward interprofessional collaborative learning among students in the health professions, especially as part of a larger multidimensional assessment process.
