Abstract

BACKGROUND: Persons with moderate to severe TBI are at increased risk for unintentional injury or harm in the home and community; however, there is currently no standard measure of safety risk they face now and in the future. OBJECTIVE: To develop comprehensive and content valid scales and item pools for assessing safety and risk for persons with moderate to severe traumatic brain injuries. METHOD: Qualitative psychometric methods for developing scales and items were used including literature review, item development and revision, focus groups with interdisciplinary rehabilitation staff (n = 26) for rating content validity, and cognitive interviewing of TBI family members (n = 9) for assuring item clarity. RESULTS: The Safety Assessment Measure is comprised of 6 primary scales - Cognitive Capacity, Visuomotor Capacity, Wheelchair Use, Risk Perception, Self-Regulation, and Compliance Failures with Safety Recommendations - in which family caregivers or clinicians rate the risk for unintentional injury or harm in adults who have sustained moderate or severe TBI. The scale item pools encompass a broad spectrum of everyday activities that pose risk in the home and community and were rated as having excellent levels of content validity. CONCLUSIONS: The Safety Assessment Measure scales and items cover a broad range of instrumental activities of daily living that can increase the risk of unintentional injuries or harm. Empirical evidence suggests that the Safety Assessment Measure items have excellent content validity. Future research should use modern psychometric methods to examine each scale unidimensionality, model fit, and precision.
