The present study theoretically and methodologically specifies and expands the concept of child misbehavior of the study of corporal punishment (CP). It introduced a new concept and measure designated "Willingness to Use CP." The findings of this study provide initial support for the validity and reliability of this measure among 204 Israeli mothers with at least one child in the first or second elementary school grade. These findings also indicate that the measure is affected by the extent to which the misbehavior offends the mother and by the risk it puts the child in. However, the weight of the former was higher than the latter. It appears that the extent to which the mother feels offended depends on the distance between her and the focus of offense of her child’s misbehavior: The closer it is to the mother, the more offended she feels and her willingness to use CP increases. Findings also indicate that there is a strong association between willingness to use and actual use of CP, regardless of appropriateness of child behavior, child gender, and family socioeconomic status. These findings support not only the reliability and validity of this new measure but also its relevance for the study of CP.
