Child Behavior Checklists completed by parents of 1848 clinically referred American and Dutch girls aged 6-11 and 12-16 were subjected to principal components analyses with varimax rotations. For the 6-11 yr age group, seven of the nine empirically derived syndromes showed cross-national correlations ranging from 0.80 to 0.98. For 12-16-yr-old girls, all eight of the American syndromes were firmly replicated for Dutch girls with correlations ranging from 0.84 to 0.97. Furthermore, cross-national similarities in the distribution of scores for normative samples supported the use of the same syndrome scales by clinicians and researchers in the two countries.
