To describe individual-level temporal change in life satisfaction after spinal cord injury.
Individual growth curve (IGC) analysis of prospectively collected data from the National Institute on Disability, Independent Living, and Rehabilitation Research National Spinal Cord Injury Database (NSCID).
Multicenter, longitudinal database study.
Participants (N=4846) in the NSCID.
Main Outcome Measure
Rasch-transformed Satisfaction With Life Scale scores.
Individual-level trajectories reflecting life satisfaction vary extensively and are associated with demographic and injury-related characteristics. Demographic characteristics include race, sex, pre-employment and discharge marital status, and level of education; injury-related factors include days in rehabilitation, neurologic level, age at injury, and injury etiology. Results are displayed graphically by way of a computer-generated interactive tool and represent different trajectories of individual-level changes in life satisfaction.
IGC methodology allows researchers and clinicians to anticipate patient-specific trajectories through use of an automated interactive tool. Projected trajectories hold promise in facilitating planning for inpatient and outpatient services, which could enhance long-term outcomes.
