a
All regression models include the independent variables generalized anxiety disorder (GAD), Social phobia (SoPh), and separation anxiety disorder (SAD), age and IQ. Age and IQ were not significant predictors in any model. Models differ by their dependent variable: self-report total ARI score, parent-report total ARI score, and average of parent and self-report total ARI score.
b
Since disorders are entered into the model as “present or absent,” parameter estimates (b) may be interpreted as the average increase in total ARI score associated with that disorder.
