Meta-Regressions

Effect of Time Since Injury

In order to address the effects of time since injury on the severity of internalizing problems, a random effects meta-regression was conducted. The Hedge's g of 17 samples was regressed on time since injury. Severity of injury was controlled for by including the GCS score as a covariate. Overall, the model was nonsignificant Q(2) = 3.66, p = .1603.  Goodness of fit analyses revealed that the model revealed a significant, non-zero proportion of variance  Q(16) = 38.93,  p = .0004. The calculated R2  analog was 0.11. The coefficients and confidence intervals are included reported in Table ?.
