Developmental Behaviour Checklist (DBC) ©

What is the Developmental Behaviour Checklist (DBC)?

The DBC is a suite of instruments for the assessment of behavioural and emotional problems of children, adolescents and adults with developmental and intellectual disabilities.

The Developmental   Behaviour Checklist, (DBC), (Einfeld & Tonge, 1992, 1995; 2002) is a   questionnaire which is completed by parents or other primary carers or   teachers, reporting problems over a six month period. Each behavioural description is scored on a 0, 1, 2 rating where 0 = ‘not true as far as you know', 1 = ‘somewhat or sometimes true', and 2 = ‘very true or  often  true'.
