摘要

Primary objective: To investigate the internal consistency, long-term stability and validity of the Life Satisfaction Index-A (LSI-A) in a sample of survivors of traumatic brain injury (TBI). Research design: Cohort study. Methods and procedures: LSI-A was administered to survivors of TBI at 12, 24, 48 and 60 months post-injury during telephone interviews. Participants rated their quality of life, independence and participation in activities as well as health status at 24 months. Internal consistency was evaluated with Coefficient alpha. Pearson's r was used to investigate score stability. Test validity was explored with Pearson's r and Analysis of Covariance with age and sex as covariates. Experimental interventions: None. Main outcomes and results: Coefficient alphas ranged from 0.85-0.92. Test-re-test coefficients ranged from 0.42-0.77. The LSI-A was positively correlated with self-reported quality of life, independence, activity level and health status. Conclusions: The LSI-A is a reliable and valid measure of the construct of life satisfaction among survivors of TBI.
