Psychometric Evaluation of the Care Transition Measure in TRACE-CORE: Do We Need a Better Measure?

摘要

Background The quality of transitional care is associated with important health outcomes such as rehospitalization and costs. The widely used Care Transitions Measure (CTM-15) was developed with a classic test theory approach; its short version (CTM-3) was included in the CAHPS Hospital Survey. We conducted a psychometric evaluation of both measures and explored whether item response theory (IRT) could produce a more precise measure.
