Factor analytic studies of one of the widely used measurements of parental discipline, the Parenting Scale (PS), have yielded ambiguous results. The purpose of this study was to compare various forms of the PS in terms of factor structure and other psychometric properties. The sample consisted of 617 mothers and 430 fathers of 2 to 5-year-olds. Confirmatory factor analysis indicated that shorter structural models provided a better fit compared to the original model; however, none led to an optimal fit. Other psychometric properties such as internal consistency, test-retest reliability, concurrent and predictive validity were slightly higher for the original Laxness and Overreactivity subscales. The findings from this study and previous studies suggest that the inter-item relationship in the scale might be too sensitive to sample characteristics, implying that factor analysis might not be the best way to measure the scale's validity. Nevertheless, other psychometric properties support the use of the Parenting Scale in the assessment of dysfunctional parenting practices. We recommend using the original Laxness and Overreactivity subscales rather than the later models, especially for research purposes.
