Children's guilt associated with transgressions and their capacity for effortful control are both powerful forces that inhibit disruptive conduct. We examined how guilt and effortful control, repeatedly observed from toddler to preschool age, jointly predict children's disruptive outcomes in two multi-method multi-trait longitudinal studies (N's 57 and 99). Disruptive outcomes were rated by mothers at 73 months (Study 1) and mothers, fathers, and teachers at 52 and 67 months (Study 2). In both studies, guilt moderated effects of effortful control: For highly guilt-prone children, variations in effortful control were unrelated to future disruptive outcomes, but for children who were less guilt prone, effortful control predicted such outcomes. Guilt may inhibit transgressions through an automatic response due to negative arousal triggered by memories of past wrongdoing, regardless of child capacity for deliberate inhibition. Effortful control that engages a deliberate restraint may offset risk for disruptive conduct conferred by low guilt.

Background Implications of early attachment have been extensively studied, but little is known about its long-term indirect sequelae, where early security organization moderates future parent-child relationships, serving as a catalyst for adaptive and maladaptive processes. Two longitudinal multi-trait multi-method studies examined whether early security amplified beneficial effects of children's willing, receptive stance toward the parent on socialization outcomes. Methods We examined parent-child early attachment organization, assessed in Strange Situation at 14–15 months, as moderating links between children's willing stance toward parents and socialization outcomes in Study 1 (108 mothers and children, followed to 73 months) and Study 2 (101 mothers, fathers, and children, followed to 80 months). Children's willing stance was observed as committed compliance at 14 and 22 months in Study 1, and as responsiveness to the parent in naturalistic interactions and teaching contexts at 25 and 67 months in Study 2. Socialization outcomes included children's internalization of maternal prohibition, observed at 33, 45, and 56 months, and maternal ratings of children's externalizing problems at 73 months in Study 1, and mothers' and fathers' ratings of children's Oppositional Defiant Disorder and Conduct Disorder symptoms at 80 months in Study 2. Results Indirect effects of attachment were replicated across both studies and diverse measures: Attachment security significantly amplified the links between children's willing stance to mothers and all outcomes. Secure children's willing, cooperative stance to mothers predicted future successful socialization outcomes. Insecure children's willing stance conferred no beneficial effects. Conclusions Implications of early attachment extend to long-term, indirect developmental sequelae. Security in the first year serves as a catalyst for future positive socialization processes.
