The value of the Parenting Scale for measuring the discipline practices of parents of middle school children.

The psychometric properties of the Parenting Scale (Arnold, O'Leary, Wolff, and Acker, 1993), a 30-item instrument originally developed to assess the discipline practices of parents of preschool children, were examined for parents of middle school students. Subjects were 298 parents of middle school student identified as at-risk for problem behavior. An exploratory factor analysis identified two factors labeled 'Overreactivity' and 'Laxness', closely resembling two of the factors found by Arnold et al., but each of these factors contained only six items. Confirmatory factor analyses, using data from the first two assessments, replicated this factor structure. The factors were significantly correlated with measures of parents' behavior, with scales from the child Behavior Checklist and Parent Daily Reports, and with the Beck Depression Inventory. The Laxness factor was less robust than the Overreactivity factor.
