ABSTRACT
Recent research has suggested that individuals may respond to differing treatment approaches with varying degrees of success depending upon their personality characteristics. The current paper attempts to examine how a tendency to engage in externalizing behaviors, as measured by the Child Behavior Checklist, may impact on treatment success for anxiety in a sample of 71 children. Results lend preliminary support to the hypothesis that the presence of an externalizing behavior disorder in a child may interfere with treatment success for anxiety disorders.
