Findling et al. (2005) used the 1991 version of the Achenbach scales, which did not include the DSM oriented subscales; Youngstrom et al. (2005) used the 2001 version.

^aAcademic Clinic AUC significantly greater than Community Clinic AUC, z = 3.03, p = .002. Note that this difference would not survive post hoc correction for number of comparisons.

^bThe DSM-Oriented scales were only available in the later protocol (Youngstrom et al., 2005), which used the 2001 version of the Achenbach instruments.
