The present study examined agreement between scores obtained from self-reports of behavioral and emotional problems obtained from 513 Algerian adolescents on the Youth Self-Report (YSR) with scores obtained from reports provided by their parents on the Child Behavior Checklist (CBCL). The correlations between self- and parent-report were larger than those observed in many other cultures (e.g., intraclass correlation coefficient = 0.60 and Pearson r = 0.65 for Total Problems). On the whole, cross-informant agreement did not vary significantly as a function of problem type, identity of the parental informant, gender and age of the adolescent. Similar to all studied cultures, adolescents on average reported more problems than their parents reported about them, but the discrepancies were smaller than in all previous societies. Mean YSR/CBCL score discrepancies indicated higher YSR scores for several scales, but variability across dyads was large, and many dyads showed the opposite pattern. (Contains 3 tables.)
