Background.Limited self-awareness of disabilities can compromise individuals' occupational performance. Purpose.The Assessment of Awareness of Disability (AAD) provides occupational therapists with a standardized methodology for measuring clients' self-awareness when performing activities of daily living (ADL). This is the first study that formally examines the stability of the AAD measures. Methods.The AAD was administered twice to 15 participants with acquired brain injury (ABI) within one or two days. One participant's data were excluded because significant changes in his ADL process abilities were detected. Two criteria were used to examine the stability of the remaining 14 participants' AAD measures: standardized diference Z-scores and a difference of 0.65 logits. Findings.All 14 participants' AAD measures were stable on the basis of their Z-scores; 13 participants' measures were stable based on the 0.65 logit difference. Implications.Occupational therapists can have confidence that the AAD generates stable measures when administered to adults with ABI.
