Abstract-For this study, we investigated the reliability and validity of the FSS (Family Satisfaction Scale) in survivors of traumatic brain injury (TBI). The FSS was administered during the 12- and 60-month follow-up interviews. Data analyses included Cronbach's Alpha to determine internal consistency and analysis of variance to determine the relationship of FSS total score to Life Satisfaction Index-A (LSI-A) total scores, marital status, living arrangement, and number of family contacts outside the home. Cronbach's Alphas were 0.94 (12 months, N = 541) and 0.95 (60 months, N = 340). FSS total score and marital status were significantly related at both 12 months [F(3, 534) = 6.04, p < 0.001] and 60 months postdischarge [F(3,335) = 4.52, p < 0.005]. FSS total scores are correlated with the number of family contacts (r342 = 0.12, p < 0.03) and with LSI-A total scores (r337 = 0.43, p < 0.001). The FSS has excellent internal consistency with survivors of TBI. We also demonstrated the evidence of convergent validity.

Key words: Family Satisfaction Scale, reliability, traumatic brain injury, validity.
