Note. M1 = constrained model; M2 = Full model; General = general factor; BPD = BPD group specific factor; AAB = AAB group specific factor; R2 = proportion of variance explained in the criterion by the model; ΔR2 = Change in R2; f2 = the proportion of variance uniquely counted for by the specific factors above and beyond the general factor.
