Since this module contains questions referring to the primary problem, patients with no agreement regarding primary problem on MATE-Q and MATE 2.1 were excluded (n = 5).
Cronbach's alpha is reported for MATE-Q/MATE 2.1.
Range 0–12 (92% of the patients reported 3 or less treatment episodes).
MATE-Q before: ICC = 0.49 (95% BI 0.29–0.64); MATE-Q after: ICC = 0.97 (95% BI 0.92–0.98).
MATE-Q before: ICC = 0.62 (95% BI 0.45–0.74); MATE-Q after: ICC = 0.88 (95% BI 0.75–0.95).
