Amsterdam Instrumental Activity of Daily Living Questionnaire (A-IADL-Q)
The Amsterdam IADL Questionnaire (A-IADL-Q) is an adaptive and computerized questionnaire designed to assess impairments in instrumental activities of daily living (IADL) in (early) dementia. The questionnaire is completed by a caregiver, such as a relative or friend.
The A-IADL-Q was developed in a memory clinic setting, with input from patients and caregivers, experts and researchers . It was demonstrated to be both a reliable and valid instrument in the evaluation of dementia . For the clinical application, it was found to have a good diagnostic value  and be sensitive to capturing changes over time .
The original questionnaire consists of 70 items in seven categories, the administration time is approximately 20-25 minutes. A recently developed short version (A-IADL-Q-SV) consist of 30 items in the same seven categories. The administration time of the short version is approximately 10 minutes shorter, thus making it more user-friendly. It was found that, although significantly shorter, the A-IADL-Q-SV, maintained the psychometric qualities of the original version .
