Social Cognition Mediates the Relation Between Attachment Schemas and Posttraumatic Stress Disorder.

Objective: A social–cognitive perspective on posttraumatic stress disorder (PTSD) has been proposed and posits that impaired social cognition, rooted in attachment insecurity, plays a role in the development of PTSD. Support for the role of impaired social cognition in PTSD has been found in adults, but the social–cognitive perspective on PTSD has not been examined in adolescents. This study sought to explore differences in social cognition and PTSD on the basis of attachment security, and it examined social cognition as a mediator in the relation between attachment security and PTSD and with regard to PTSD symptom change during inpatient treatment. Method: We recruited 142 adolescents from an inpatient psychiatric hospital, where adolescents and their parents completed assessments at admission and discharge. Results: Adolescents with a secure attachment demonstrated better social–cognitive skills than did those with an insecure attachment. Social cognition mediated the relation between adolescents’ maternal attachment representations and PTSD at admission across 3 self- and parent-report measures. Social cognition also mediated the relation between adolescents’ maternal attachment representations at admission and PTSD treatment outcome. Conclusion: This study provides the 1st support for the application of Sharp, Fonagy, and Allen’s (2012) social–cognitive perspective of PTSD to adolescents by showing a link between clinically significant symptoms of PTSD and attachment security through social–cognitive impairment. Findings indicate that improvement in PTSD during medium-stay inpatient treatment is partially driven by baseline attachment security and social–cognitive abilities, highlighting the potential of social–cognitive skills as important targets of clinical intervention among adolescents with PTSD.

Experiential avoidance in the vulnerability to depression among adolescent females

BACKGROUND Although various mechanisms in the maternal transmission of Major Depressive Disorder (MDD) have been investigated, it is unknown whether experiential avoidance (EA) is a vulnerability factor in the development of depression or a consequence of the illness. The present study utilized a high-risk design to determine if EA indeed poses vulnerability to adolescent MDD. Secondly, we examined the means by which adolescent EA may come to pose vulnerability, namely that it explains the relation between maternal EA and adolescent depressive symptoms. METHODS One-hundred and forty-six biological mother/adolescent daughter dyads comprised three diagnostic groups: mothers with a history of MDD and their depressed daughters (MDD; n=21), mothers with a history of MDD and their never-depressed daughters (high-risk, HR; n=69), and healthy controls (HCs; n=56). RESULTS Groups differed on daughter EA such that the MDD group reported greater EA than the HR group, which in turn reported greater EA than HCs. Daughter EA mediated the relation between maternal EA and daughter depressive symptoms after controlling for maternal depressive symptoms. LIMITATIONS Strengths aside, this study included a relatively small group of depressed mother-daughter dyads and relied on cross-sectional self-report data. CONCLUSIONS EA appears to serve as a vulnerability factor for adolescent MDD, and the mechanistic role of daughter EA highlights the significance of intergenerational EA in the maternal transmission of depression. Therapeutic approaches may therefore consider reducing the transmission of EA from mothers to daughters.

Current maternal depression moderates the relation between critical expressed emotion in mothers and depressive symptoms in their adolescent daughters.

Prior studies have examined critical expressed emotion (EE-Crit) in mothers in the intergenerational transmission of depression. However, the potential moderating effect of maternal depression diagnostic status in relation to EE-Crit and youth depressive symptoms has yet to be determined. A total of N=121 biological mother/daughter dyads that differed in maternal depression diagnostic status were recruited for the present study: (1) currently depressed mothers (current depression, n=29); (2) formerly depressed mothers (past depression, n=39); and (3) mothers free from any psychiatric history (healthy controls, n=53). Mothers were administered structured clinical interviews and completed self-report measures of EE-Crit and psychopathology, and daughters self-reported depressive symptoms. Results indicated no significant group differences in EE-Crit; however, current maternal depression status moderated EE-Crit such that the magnitude of the relation between EE-Crit and adolescent depressive symptoms was significantly greater in daughters of currently depressed mothers. These findings highlight the importance of considering current maternal depression, rather than a history of maternal depression, in relation to EE-Crit and adolescent depressive symptoms, providing impetus for future investigations.

Dating Violence Victimization, Nonsuicidal Self-Injury, and the Moderating Effect of Borderline Personality Disorder Features in Adolescent Inpatients

The aim of the study was to examine whether Borderline Personality Disorder (BPD) features moderate the relation between dating violence victimization (DVV) experiences and nonsuicidal self-injury (NSSI) in adolescent inpatients. A total of 184 adolescent inpatients completed measures on DVV, BPD features, and NSSI at admission to treatment. Bivariate analyses revealed significant relations between DVV, BPD features, and NSSI. Hierarchical multiple regression analyses demonstrated a moderating effect of BPD features such that in the low BPD features group, more severe DVV was associated with greater NSSI frequency; adolescents in the high BPD group endorsed elevated, though stable, levels of NSSI at all levels of DVV. BPD features differentially affect the relationship between DVV and NSSI. Low BPD adolescents exposed to high DVV appear to self-injure more frequently and at rates similar to high BPD adolescents when faced with more severe DVV, while DVV appears neither necessary nor sufficient to be the cause of NSSI in high BPD adolescents. Our results indicate that DVV may be a particularly important focal point for treating adolescents who self-injure and have been victimized by a dating partner. As such, Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) and Dialectical Behavior Therapy (DBT) may serve as valuable clinical interventions.
