Developmental Behavior Checklist for Adults

The Developmental Behavior Checklist 2 (DBC2) describes emotional and behavioral problems in people with intellectual and developmental disability. Its items were derived from clinical records of that population rather than adapted from a general-population rating scale, so it asks about the difficulties that actually come up.

Someone who knows the person well — a family member or paid carer — rates each behavior over the past six months as not true, somewhat or sometimes true, or very true. Five subscales emerge: disruptive or antisocial, self-absorbed, communication disturbance, anxiety, and social relating, which combine into a total score. Norms are provided by level of disability, so a person's score is read against others with a comparable degree of impairment.
