Conners 3-Parent (Short): Measurement Invariance Across Gender, Concurrent and Discriminant Validities

The study examined measurement invariance (configural, factor loadings, thresholds, and error variances), and equivalencies of latent mean scores of the Conners 3-Parent (Short); (C 3-P (S)) across maternal ratings of clinic-referred boys (N = 354) and girls (N = 151), aged 7 to 17 years. It also examined the concurrent and discriminant validities of the scores for the C 3-P (S). Confirmatory factor analysis (CFA) indicated support for the theorized six-factor model. For this model, there was support for full measurement invariance and equivalencies for the latent mean scores. There was also support for the concurrent and discriminant validities of the scores for the C 3-P (S) scales. The findings are discussed in relation to the use of the C 3-P (S).
