Definition

The DAFS is a standardized observation-based checklist designed to assess functional capabilities of adults with Alzheimer’s disease, dementia, and schizophrenia. It can be used for evaluation and reevaluation to assess any decline and effect on function of pharmacological intervention. Intended for use in outpatient settings, the DAFS requires approximately 30–35 min to administer. The examiner needs the evaluation form, pen or pencil, and ADL materials for testing. Simulated daily tasks are observed in the seven following areas: time orientation (score range 0–8), communication (score range 0–9), transportation (score range 0–13), finance (score range 0–7), shopping (score range 0–6), grooming (score range 0–13), and eating (score range 0–10; Loewenstein et al. 1989). Possible total composite scores range from 0 to 106, with higher scores indicating better functioning.
