Preliminary evaluation of a measure for reliable assessment of need for constant visual observation in adults with traumatic brain injury.

Primary Objective: To develop and provide initial validation of a measure for accurately determining the need for Constant Visual Observation (CVO) in patients with traumatic brain injury (TBI) admitted to inpatient rehabilitation.

Research Design: Rating scale development and evaluation through Rasch analysis and assessment of concurrent validity.

Methods And Procedures: One hundred and thirty-four individuals with moderate-severe TBI were studied in seven inpatient brain rehabilitation units associated with the National Institute for Disability, Independent Living and Rehabilitation Research (NIDILRR) TBI Model System.
