^aHighlighted response options were combined for purposes of data harmonization due to the categories having fewer than five respondents.

^bThe ADL Abbrev scale uses a time referent of compared to 5 years ago to capture current ability level on certain tasks, skills, or problem areas in relation to previous ability. As such, even though labeled as “C”, indicating that it assesses change, the ADL Abbrev also taps into ability.

Note. SEM = Standard Error of Measurement; ADL Abbreviated = Activities of Daily Living Rating Scale Self-Version, Abbreviated; CFI = Cognitive Function Index; MAC-Q (a) = Memory Complaint Questionnaire; MMQ = Multifactorial Memory Questionnaire.
