To diagnose a mental disorder or make a disability determination, clinicians must assess functional impairment not just the presence of symptoms. Meeting a key need, the Barkley Functional Impairment Scale Children and Adolescents (BFIS-CA) is an empirically based, norm-referenced tool that exceeds other available scales in its comprehensive coverage of domains of psychosocial impairment. The BFIS-CA is designed to obtain parent reports on possible impairment in 15 different domains of everyday activities for children and teens. The scale typically takes a parent 5-7 minutes to complete. Also included is a follow-up parent interview form for obtaining more information on specific problem areas. Age range: 6-17.
