- report a high level of upset with behaviors as follows. We will use the Agitated Behavior in Dementia Scale (ABID),62 which is a 16-item psychometrically valid scale of behavioral occurrences and associated caregiver upset. We chose this scale out of the six primary scales used to measure behavior given that the behaviors most closely match the intent of the intervention we plan to test. The behaviors include those listed earlier plus one additional behavior, repetitive vocalization. For each of these 17 behaviors that occur in the past week (for the purposes of screening eligibility, we will use a yes/no response format), caregivers are asked their level of upset (0 = not at all, 1 = a little, 2 = moderately, 3 = very much and 4 = extremely).
