Abstract
The purpose of the present study was to examine the relationship among three types of outcome measures that have been employed to evaluate parent behavioral training: observational data collected by independent observers, parent-collected data, and parent-completed questionnaires. Previous research suggests that all three measures yield positive outcome data; however, a correlational analysis has not been performed to determine if the subjects who demonstrate the largest (smallest) change on one measure demonstrate the largest (smallest) change on the other measures. The present study undertook such a correlational analysis. Subjects were 20 young clinic-referred children and their mothers. Treatment consisted of a standardized parent training program to modifly child noncompliance. All three outcome measures (observational data, parent-collected data, and questionnaire data) indicated that therapy was effective. A correlational analysis performed on the outcome measures indicated a number of significant relationships for dependent variables withinthe observational data and withinthe questionnaire data; however, there were no significant relationships acrossthe three outcome measures. Although different outcome measures may yield similar conclusions about the effectiveness of parent behavioral training, the results suggest that any one subject, relative to other subjects, does not demonstrate uniform degrees of change across the three outcome measures. Explanations for the findings, as well as their implications, are discussed.
