This study examined whether the link between higher maternal sensitive guidance of emotional dialogues and fewer adolescent behavior problems is mediated by adolescents' more coherent representations of their mothers. The study also explored the consistency of this model across families from varied cultural backgrounds. Participants were 143 Jewish‐Israeli mother–adolescent dyads from three cultural groups: immigrants from the Former Soviet Union, immigrants from Western countries, and native‐born Israelis. Maternal sensitive guidance was observed during mother–adolescent dialogues about emotional experiences. Adolescents' representations were assessed via their narratives regarding their mother and their relationship. Examiners reported adolescents' behavior problems. Results indicated that across cultural groups adolescents' more coherent representations partially mediated the association between higher maternal sensitive guidance and fewer adolescent behavior problems.
