Measuring unmet needs and services among persons with traumatic brain injury

Objectives: (1) To develop a comprehensive list of needs and services appropriate for persons with traumatic brain injury (TBI); (2) to determine whether these needs and services formed unidimensional hierarchies from least common to most common; (3) to describe the relationship between unmet needs and services received; and (4) to estimate the extent to which a variety of demographic, injury, and service characteristics predict unmet needs. Design: Statewide mailed survey. Setting: Illinois communities. Participants: A total of 895 persons who had had a TBI recruited from Brain Injury Association members and rehabilitation service recipients. The median time post-TBI was 7 years; the median age was 37 years. Interventions: Not applicable, Main Outcome Measures: A 27-item instrument assessing service needs and utilization of services, and equal-interval measures of needs and services derived with Rasch analysis. Results: The most prevalent unmet needs were improving memory or problem-solving skills (51.9%), increasing income (50.5%), and improving job skills (46.3%). The instrument defined unidimensional and reliable constructs of needs and services. Persons with greater unmet needs tended to receive fewer services; to report lower life satisfaction and worse medical health and psychologic well-being since injury; to be younger, single, black, dependent in 1 or more daily activities; and to have more recent injuries. Conclusions: The results show the common pattern of unmet needs and services and emphasize the importance of comprehensive, statewide assessment of services and needs in developing policies.
