[Adaptive behavior scale for persons with profound intellectual disability]

An adaptive behavior scale for persons with profound intellectual disability was proposed. This scale consisted of 64 items from five areas: interpersonal relationship, perception, expression, interest and play, and daily life. Each item was scored on a 0-2 scale. Forty-eight institutionalized persons (23 males, 25 females) with profound intellectual disability, aged 13-69 (mean 40) years, were examined with this scale. The rating for each item was 0.02-1.81 (mean 0.88). On 69% of the items, estimates were consistent between two care-staffs. The Cronbach's alpha value was calculated to be 0.97, indicating good internal consistency. On the whole, this scale is useful in assessing adaptive behaviors of the subjects.
