This research examined the convergent and discriminant validity of the Academic Competence Evaluation Scales (ACES; DiPerna & Elliott, 2000) and the Learning Behaviors Scale (LBS; McDermott, Green, Francis, & Stott, 2001). The Adjustment Scales for Children and Adolescents (ASCA; McDermott, Stott, & Marston, 1993) was compared with the ACES and LBS to examine discriminant validity. Pearson product moment correlations were obtained to examine convergent and discriminant validity. Paired samples t-tests were conducted on the ACES and LBS total and subscale scores to compare the mean scores. The ACES Academic Enabler (ACES-AE) total score was significantly, positively correlated with the LBS total score (r =0.88) and shared 77% variance. Paired samples t-test analyses indicated that the ACES-AE Total T score (M = 46.83, SD = 10.63) was significantly higher than the LBS Total T score (M = 42.18, SD = 13.81), t(97) = 5.47, p < .001, d = .38. However, although teacher ratings on the ACES-AE were significantly higher than the LBS, the effect size was small and likely not meaningful. Both the ACES-AE and the LBS Total score were moderately, negatively correlated with the ASCA Overactivity score (r = -0.43 and r = -0.55, respectively) with 18% and 30% shared variance and the ASCA Underactivity score (r = -0.42 and r = -0.32, respectively), with 18% and 10% shared variance. The ACES and LBS demonstrated convergence (they measured similar constructs) while they each demonstrated discriminant validity when compared with the ASCA (these correlations were mostly lower than ACES/LBS correlations). Thus, the current study found construct validity support for the ACES and LBS.
