Abstract
Objectives
The Choosing Wisely Questions (CWQ) support shared decision-making and aim to reduce low-value care, but their psychometric properties remain unclear. This study evaluated the structural validity, reliability, and item characteristics of the Swedish CWQ in a psychiatric sample.
Methods
In this cross-sectional study, adult patients at a Swedish university psychiatric clinic (early 2025) completed four CWQ items on perceived information about their medication (benefits, risks, alternatives, and no treatment). Structural validity was assessed using exploratory and confirmatory factor analyses. Internal consistency was measured with Cronbach's alpha, and item characteristics were examined using a graded response model.
