Mentions: The presence of significant cohort interactions revealed differences in the effect of some child and maternal characteristics on CBCL scores between cohorts (Table S3). Interaction effects were most consistently identified between cohort and family assets (Figure3), maternal schooling and maternal psychiatric problems (Figures S1a–S1d). CBCL score increases between 1993 and 2004 were more observable in children from families in the lower asset quintiles (compared with the highest asset quintile) and in children with less educated mothers. Children from families in the highest asset quintile and with highly educated mothers showed almost no increase in behavioral problems between 1993 and 2004.
