To diagnose a mental disorder or evaluate a disability claim, clinicians must assess functional impairment -not just the presence of symptoms. Meeting a key need, the Barkley Functional Impairment Scale (BFIS) is the first empirically based, norm-referenced tool designed to evaluate possible impairment in 15 major domains of psychosocial functioning in adults. Featuring both self-report and other-report forms (for example, spouse, parent, or sibling), the BFIS is reliable, valid, and user friendly. Purchasers get a limited license to reproduce the forms and score sheets without the expense of reordering materials from the publisher; the large format and sturdy wire binding facilitate photocopying. The long version takes the average adult 5-7 minutes to complete, and the Quick Screen takes only 3-5 minutes. This book will be important reading for clinical and forensic psychologists, neuropsychologists, social workers, psychiatrists and psychopathology researchers.
