Internalizing Symptoms in Adolescents: Gender Differences in Vulnerability to Parental Distress and Discord

This longitudinal study investigated gender differences in the relation between (1) internalizing symptoms of depression and anxiety reported by adolescents, and (2) emotional distress and marital discord reported by their mothers. Structural equation modeling was used to track the relationship between these variables in a community sample of 116 males and 101 females and their parents across three data intervals roughly corresponding to early adolescence (M = 11,4), mid-adolescence (M = 13,7), and late adolescence/early adulthood (M = 19,2). For early adolescents, there were no gender differences in the relation between internalizing symptoms and parental distress and discord. Gender differences did emerge, however, by midadolescence, at which time parental disturbances were significantly associated with internalizing symptoms in adolescent females but not adolescent males. The emergence of this risk factor during this developmental phase may help account for frequent findings that place adolescent females at higher risk for anxiety and depression than adolescent males.

Comorbid Axis I and Axis II Disorders in Early Adolescence: Outcomes 20 Years Later

CONTEXT Although Axis II personality disorders in adolescence have been linked to psychopathology and psychosocial impairment in early adulthood, little is known about their effects over longer periods. OBJECTIVES To evaluate and compare long-term prognoses of adolescent personality disorders and co-occurring Axis I disorders. DESIGN Population-based longitudinal study. SETTING Upstate New York. PARTICIPANTS A community sample of 629 adolescents interviewed at a mean age of 13.8 years and again at a mean age of 33.2 years. MAIN OUTCOME MEASURES Clinically assessed psychiatric disorders and self-reported attainment and function. RESULTS Axis I (mood, anxiety, disruptive behavior, and substance use disorders) and Axis II disorders in adolescence showed risks for negative prognoses lasting 20 years. Co-occurring Axis I and Axis II disorders consistently presented the highest risk, often approximating the sum of the axis-associated risk or even several times the risk of disorders in either axis alone. CONCLUSIONS Long-term prognoses of Axis I and Axis II disorders are of comparable magnitude and often additive when comorbid. These findings are highly relevant to the current debate over how personality disorders should be handled in DSM-V.

Insecure attachment and personality disorder: a twin study of adults

This study used 239 twin pairs from a volunteer community sample to investigate how anxious and avoidant attachment are related to personality disorder (PD). Factor analysis showed that self‐reported anxious attachment and 11 PD scales from the Dimensional Assessment of Personality Problems loaded onto one factor (emotional dysregulation), and avoidant attachment and four PD scales loaded onto a second factor (inhibitedness). Biometric models indicated that 40% of the variance in anxious attachment was heritable, and 63% of its association with corresponding PD dimensions was attributable to common genetic effects. Avoidant attachment was influenced by the shared environment instead of genes. Correlations between avoidance and corresponding PD dimensions were attributable to experiences in the nonshared environment that influenced both variables. Copyright

Early maternal separation and the trajectory of borderline personality disorder symptoms

Extended maternal separations before age 5 were evaluated as a predictor of long-term risk for offspring borderline personality disorder (BPD) symptoms in longitudinal data from a large random community sample. Early separations from mother predicted elevations in BPD symptoms assessed repeatedly from early adolescence to middle adulthood. Early separations also predicted a slower than normal rate of decline in symptoms with age. Other theoretically grounded risks were examined and shown to predict elevated BPD symptoms over the developmental trajectory. Long-term effects of early separations were largely independent of childhood temperament, child abuse, maternal problems, and parenting risks. These data provide the first prospectively collected data on the developmental course of BPD symptoms and suggest a series of environmental and other influences on these very disabling problems.

Gender differences in the age-changing relationship between instrumentality and family contact in emerging adulthood.

Data from the Children in the Community Transitions Study were used to examine gender differences in the impact of family contact on the development of finance and romance instrumentality from ages 17 to 27 years. Family contact decreased among both men and women across emerging adulthood, although it decreased more rapidly in men than in women. Both finance and romance instrumentality increased for men and women across emerging adulthood. The growth rate did not differ between men and women in either domain, although men tended to be characterized by higher levels of instrumentality than women. There were noteworthy gender differences in the impact of family contact on the development of instrumentality. At age 17, family contact was negatively associated with instrumentality for both men and women; at age 27, the impact of family contact on instrumentality was less negative for women and was positive for men.

Associations of Parental Personality Disorders and Axis I Disorders with Childrearing Behavior

Abstract Data from the Children in the Community Study, a community–based longitudinal investigation, were used to investigate the associations of parental anxiety, depressive, substance use, and personality disorders with parental child rearing behavior. Comprehensive psychosocial interviews, including assessments of child rearing, were conducted with 224 women and 153 men (mean age = 33 years; mean off- spring age = 8 years). Findings indicated that parental personality disorders were associated with parental possessiveness, inconsistent parental discipline, low parental communication, and low parental praise and encouragement. These associations remained significant when parental gender, offspring gender, and co–occurring parental disorders were controlled statistically. Parental anxiety disorders were independently associated with parental possessiveness. Parents with personality disorders were substantially more likely than parents without personality disorders to report engaging in multiple problematic child rearing behaviors. This association was not moderated by co–occurring parental disorders. These findings suggest that the presence of a parental personality disorder may be associated with an elevated likelihood of problematic parenting behavior during the child rearing years.

Social Role and Birth Cohort Influences on Gender-Linked Personality Traits in Women: A 20-Year Longitudinal Analysis

Growth curve modeling was used to examine the impact of social role experiences (e.g., marital support, occupational prestige) and birth cohort on mean-level differences and age-related changes in positive personality traits indicative of either femininity or masculinity in 758 mothers heterogeneous in age, assessed 4 times over 2 decades. Both femininity and masculinity increased significantly from mean ages 39 through 59; each was predictive of an age change in the other. Low masculinity was associated with a more rapid increase in femininity, whereas high occupational prestige decreased the magnitude of association between masculinity and femininity. Femininity increased with more marital support but decreased with unmarried status, more children at home, and working full or part time; among full-time workers, that effect was modified by marital support. Masculinity increased with full-time work and high occupational prestige. A trend for differing levels of femininity, and contrasting associations of masculinity with femininity and marital conflict in women born after 1944 compared with those born earlier, suggests shifting social norms and gender relations in the marital role.

Adolescent Cluster A personality disorder symptoms, role assumption in the transition to adulthood, and resolution or persistence of symptoms

Cluster A odd or eccentric personality disorder (PD) symptoms may reflect a schizophrenia spectrum biological vulnerability in at least some persons. Consequently, this symptom pattern may have particularly negative effects on the transition from adolescent to adult roles. A general population sample of 200 young adults was assessed on Cluster A PD at mean ages 17 and 22, and subsequently provided detailed narratives about their monthly experiences and behaviors between these two ages. Adolescent Cluster A PD was related to the developmental trajectories of residential, career, financial, romantic, and family formation roles during this period, and trajectories were related to a change in symptoms over this period. Symptoms were associated with early parenthood and less advanced education, but for other developmental outcomes tended to differ for men and women. These gender differences were attributable, in part, to the differential meaning and consequences of early parenthood for men and women.

School Climate and Continuity of Adolescent Personality Disorder Symptoms.

BACKGROUND Schools are key social contexts for shaping development and behavior in youths; yet, little is known of their influence on adolescent personality disturbance. METHOD A community-based sample of 592 adolescents was assessed for family and school experiences, Axis I psychiatric disorders, and Axis II personality disorder (PD) symptoms, and followed into young adulthood. Multiple regression analysis was used to estimate associations between adolescent-reported school climate and young adult PD symptoms independent of age, sex, family socioeconomic status; childhood maltreatment; Axis I disorder, PD symptoms, academic grades, and parental punishment in adolescence; and four dimensions of school climate. RESULTS Schools characterized as high in learning focus were related to cluster B (antisocial, borderline, histrionic, and narcissistic PD) symptom declines, whereas schools characterized as high in opportunities for student autonomy were related to cluster A (paranoid, schizoid, and schizotypal PD) symptom declines. In contrast, schools characterized as conflictual or supporting interpersonal informality/familiarity among students and teachers were related to increases in cluster A symptoms and cluster C (avoidant, dependent, and obsessive-compulsive PD) symptoms. CONCLUSIONS Schools may exert both positive and negative influences on continuity of adolescent personality disturbance. The role of the school in guiding young people toward more favorable developmental pathways and alleviating personality disturbance is discussed.

How affect regulation moderates the association between anxious attachment and neuroticism.

Abstract Correlations between anxious attachment and neuroticism (usually about .40 to .50) prompt questions about whether self-reported anxious attachment captures a key construct in attachment theory or if it reflects a more general personality trait instead. A college sample of late adolescents and young adults (N = 287) was used to show that questionnaire measures of neuroticism and anxious attachment do not have a simple linear association; instead, neuroticism and anxious attachment have a more complex dynamic relationship that is moderated by avoidant attachment, an attachment style that reflects an interpersonally derived strategy for affect regulation. The association between neuroticism and anxious attachment is further moderated by conscientiousness, a personality trait that may reflect a more biologically mediated system of affect regulation. These separate moderating effects and the different affect regulation systems they reflect are discussed in the context of longstanding debates about how personality traits and attachment styles influence each other.
