© 2015 American Psychological Association.There is currently no existing freely available short screen for cognitive problems that targets stroke survivors specifically. We have developed a short cognitive screen, the Oxford Cognitive Screen (OCS), to be completed in 15-20 min, designed for use with stroke patients. To maximize inclusion, the test is aphasia- and neglect friendly and covers domains of cognition where deficits frequently occur after stroke, including apraxia and unilateral neglect as well as memory, language, executive function, and number abilities. Domain-specific scores are returned to help direct rehabilitation. This article presents the normative data in a large sample of 140 neurologically healthy participants, a report on incidences of impairments in a sample of 208 acute stroke patients (within 3 weeks of stroke onset), measures of test-retest reliability on an alternate form and convergent and divergent validity. In addition, the full test materials are made freely available for clinical use.
