Guided by attachment theory, we explored in the present study the links between parental emotion-coaching, attachment to parents, and adolescent's sense of agency. Further, we examined a possible mediating role of adolescent's attachment to parents in the association between parental emotion-coaching and sense of agency. All models control for cumulative psychosocial risk, and adolescents' sex and age, and take into account the reports of both mothers and fathers. The sample included 501 Portuguese families comprising adolescents, their mothers, and their fathers. Adolescents (ages ranged from 15 to 18) reported on their attachment to parents, personal agency, and cumulative psychosocial risk, whereas mothers and fathers independently completed a questionnaire assessing their meta-emotion skills. The results indicate that both mothers' and fathers' emotional-coaching are positively associated with the quality of adolescent's attachment to parents. Nonetheless, parental emotion-coaching are not directly associate with sense of agency. The quality of emotional bond with father is linked to a more positive sense of agency, while relationships characterized by mother's inhibition of adolescent's exploration are associated with less positive perceptions of agency. Parental emotion-coaching seems to be associated with the sense of personal agency through the quality of attachment to parents. These results are discussed according to attachment theory taking into account the parents' importance to adolescents' development. Our findings provide a first attempt to unravel the possible links between parental emotion-coaching, attachment to parents, and sense of agency; nevertheless, they need to expand.
