Comparison of Two Modes of Administration of the IADL Questionnaire, Assessing the Level of Functional Autonomy of Patients to Carry Out the Tasks of Daily Living: Randomized Controlled Trial Among Patients of a Memory Clinic

The administration of IADL questionnaire by phone consists of a collection of answers given by the caregiver during the interview with the research nurse, trained for this procedure. This method of procurement will be standardized with a listing support for the phone interview to obtain the same conditions for collection of data from a caregiver to another. Questions will be asked in the same order than the questionnaire collected with the reference procedure i.e. face-to-face interview at the Memory Clinic. The IADL questionnaires in paper format used during the ace-to-face interview and by phone will be identical.
