Abstract:

Study developed, calibrated, and evaluated a new patient-reported outcome measures of cognitive concerns for individuals with traumatic brain injury (TBI). The TBI-QOL Headache Pain Executive Function and TBI-QOL Cognition-General Concerns item banks developed using data collected at five TBI Model Systems rehabilitation centers in the United States from adults with medically confirmed documentation of TBI. A total of 569 adults with complicated-mild, moderate, or severe TBI completed preliminary item pools, which included 65 Executive Function items and 56 Cognition-General Concerns items. Confirmatory factor analysis supported the retention of 37 Executive Function and 39 Cognition-General Concerns items. Samejima's graded response model was used to estimate item parameters for associated computer adaptive test administrations and informed the selection of corresponding static short forms. Data from an independent sample of 77 adults with complicated-mild, moderate, or severe TBI supported the test-retest reliability of these newly developed measures. The TBI-QOL Executive Function and Cognition-General Concerns item banks provide researchers and clinicians with reliable tools for assessing patient-reported post-TBI cognitive difficulties as part of the comprehensive TBI-QOL measurement system.
