Adjustment composite standard scores (M = 100, SD = 15) by Extended Class Play Shy-Withdrawn self-rating z-scores at different levels of Shy-Withdrawn peer ratings. S-W=Shy-Withdrawn. Higher Shy-Withdrawn scores reflect greater shyness-withdrawal. Higher adjustment composite scores reflect better adjustment. The interaction effect was significant, with follow-up analysis indicating significant differences in adjustment scores between those with low versus high peer S-W ratings only at lower levels of self S-W ratings (i.e., the left side of the graph). The findings indicate that adjustment is poorer in children who rate themselves low for shy-withdrawn behavior, but whose peers rate them high; in other words, children who underestimate their shyness-withdrawal have poorer adjustment. *p < .05.
