The effect of group on 12 month sleep disturbances was mediated through the
effect of injured groups internalizing behavior problems at 6 months. EI
= extracranial injury, TBI = traumatic brain injury, SD
= sleep disturbance, 6M = 6 month, 12 = 12 month, CI
= confidence interval, path ab1 =
indirect effect of EI on internalizing, path ab2
= indirect effect of TBI on internalizing. *
p<.05.
