Clarifying the relation between mother and adolescent borderline personality disorder symptoms: The roles of maternal and adolescent emotion regulation and maladaptive maternal emotion socialization.

Abstract

Despite evidence for the intergenerational transmission of borderline personality disorder (BPD) pathology from mothers to offspring, the factors underlying the relation between mother and child BPD symptoms remain unclear and little is known about the pathways through which maternal BPD symptoms may relate to BPD symptoms in their offspring. One set of factors that warrants consideration in this regard is mother and child emotion regulation (ER) difficulties. In particular, theory and research suggest an indirect relation between mother and child BPD symptoms through maternal ER difficulties (and related maladaptive emotion socialization strategies) and, subsequently, child ER difficulties. Thus, this study used structural equation modeling to examine a model wherein maternal BPD symptoms relate to offspring BPD symptoms in adolescence through maternal ER difficulties (and maladaptive maternal emotion socialization strategies) and, subsequently, adolescent ER difficulties. A nationwide community sample of 200 mother-adolescent dyads completed an online study. Results provided support for the proposed model, revealing both a direct relation between maternal and adolescent BPD symptoms and two indirect relations through (a) maternal and adolescent ER difficulties and (b) maternal ER difficulties, maternal maladaptive emotion socialization strategies, and adolescent ER difficulties. Results highlight the relevance of both mother and adolescent ER difficulties in the relation between mother and offspring BPD pathology, as well as the potential clinical utility of targeting mother and child ER in interventions aimed at preventing the intergenerational transmission of BPD pathology.
