Concordance rule details: No change = within 1 points of 0; Slightly <5 points in concordant direction (i.e >0); Much >= 5 points in concordant direction; Character 1 = LBP, Character 2 = tasks; - = TQ less optimistic than RMDQ change score; + = TQ more optimistic than RMDQ change score; ND = No Data/datum. For example, a participant with a discordance status of ++ indicates a more optimistic response to both transition questions relative to the RMDQ change score. A participant with status 0- would be concordant with respect to the TQ that is worded in terms of LBP, but would have a less optimistic daily task TQ as compared to the RMDQ change score. TQ anchors 1=Completely better; 2=Much better; 3=Slightly better; 4=No change, 5=Slightly worse, 6=Much worse; 7=Vastly worse. ^∗Asian or Asian British Indian. ^†Black or Black British African. ^‡White and Afro-American.
