However, the local independence of items assumption was violated between items 9 (severity of pain) and 11 (sleeping difficulty due to pain) (Yen\u2019s Q3\u2009=\u20090.46) and disordered thresholds were evident for item 5 (cutting food). After addressing these breaches of assumptions, the re-analyzed GRM with the remaining 10 items achieved an improved fit. Simulation of CAT administration demonstrated a high correlation between scores on the CAT and the <jats:italic>Quick<\/jats:italic>Dash (<jats:italic>r<\/jats:italic>\u2009=\u20090.98). Items 2 (doing heavy chores) and 8 (limiting work or daily activities) were the most frequently used.
