This study examined the Eyberg Child Behavior Inventory (ECBI) "discrepancy hypothesis", which asserts that a discrepancy in score elevations on the ECBI Intensity and Problem Scales is related to problematic parenting styles. The Intensity Scale measures the frequency of child disruptive behavior, and the Problem Scale measures parent perception of their child's behavior as problematic. In a sample of 216 female caregivers of 3- to 7-year-old children, the magnitude of discrepancy between T scores on the two ECBI scales was found to predict parental tolerance for child misbehavior. A one-standard-deviation difference in ECBI T scores identified (a) parents intolerant of their child's misbehavior when the Problem score was highest and (b) overly permissive parents when the Intensity score was highest.
