Perceived racial discrimination (PRD) has been associated with altered diurnal cortisol rhythms in past cross-sectional research. We investigate whether developmental histories of PRD, assessed prospectively, are associated with adult diurnal cortisol profiles. One-hundred and twelve (N = 50 Black, N = 62 White) adults from the Maryland Adolescent Development in Context Study provided saliva samples in adulthood (at approximately age 32 years) at waking, 30 min after waking, and at bedtime for 7 days. Diurnal cortisol measures were calculated, including waking cortisol levels, diurnal cortisol slopes, the cortisol awakening response (CAR), and average daily cortisol (AUC). These cortisol outcomes were predicted from measures of PRD obtained over a 20-year period beginning when individuals were in 7th grade (approximately age 12). Greater average PRD measured across the 20-year period predicted flatter adult diurnal cortisol slopes for both Black and White adults, and a lower CAR. Greater average PRD also predicted lower waking cortisol for Black, but not White adults. PRD experiences in adolescence accounted for many of these effects. When adolescent and young adult PRD are entered together predicting cortisol outcomes, PRD experiences in adolescence (but not young adulthood) significantly predicted flatter diurnal cortisol slopes for both Black and White adults. Adolescent, but not young adult PRD, also significantly predicted lower waking and lower average cortisol for Black adults. Young adult PRD was, however, a stronger predictor of the CAR, predicting a marginally lower CAR for Whites, and a significantly larger CAR for Blacks. Effects were robust to controlling for covariates including health behaviors, depression, income and parent education levels. PRD experiences interacted with parent education and income to predict aspects of the diurnal cortisol rhythm. Although these results suggest PRD influences on cortisol for both Blacks and Whites, the key findings suggest that the effects are more pervasive for Blacks, affecting multiple aspects of the cortisol diurnal rhythm. In addition, adolescence is a more sensitive developmental period than adulthood for the impacts of PRD on adult stress biology.

SYNOPSIS Objective Previous research has examined the developmental consequences, particularly in early childhood, of parents’ supportive and unsupportive responses to children’s negative emotions. Much less is known about factors that explain why parents respond in ways that may support or undermine their children’s emotions, and even less is known about how these parenting processes unfold with adolescents. We examined the associations between mothers’ attachment styles and their distress, harsh, and supportive responses to their adolescents’ negative emotions two years later and whether these links were mediated by maternal emotion regulation difficulties. Design Mothers in a longitudinal study (n = 230) reported on their attachment style, difficulties regulating their emotions, and their hypothetical responses to their adolescents’ negative emotions, respectively, at consecutive laboratory visits one year apart. Results Mothers who reported greater attachment-related avoidance and anxiety reported having greater difficulties with emotion regulation one year later. Emotion dysregulation, in turn, predicted more distressed, harsher, and less supportive maternal responses to adolescents’ negative emotions the following year. In addition, greater avoidance directly predicted harsher maternal responses two years later. Conclusions These findings extend previous research by identifying maternal attachment style as a predictor of responses to adolescent distress and by documenting the underlying role of emotion dysregulation in the link between adult attachment style and parenting.

Few studies have examined stability and change in attachment during adolescence. This 5-year longitudinal study (a) examined whether prototype or revisionist developmental dynamics better characterized patterns of stability and change in adolescent attachment (at T1, N = 176; M = 14.0 years, SD = 0.9), (b) tested potential moderators of prototype-like attachment stability, and (c) compared attachment stability in adolescence to stability in adulthood. The results supported the prototype model, which assumes that there is a stable, enduring factor underlying stability and change in attachment. Exploratory moderation analyses revealed that family conflict, parental separation or divorce, minority status, and male sex might undermine the prototype-like stability of adolescent attachment. Stability of attachment was lower in adolescence relative to adulthood.

We examined a new structured interview of parent–child conflict that assesses parent and child perceptions of behavioral conflict about daily life topics (e.g., doing chores, homework), and whether discrepancies exist on beliefs about these topics. In a sample of 100 parents and children ages 10 to 17 years (M=13.5 years, 52 males, 57 % African-American), informants could reliably distinguish between perceived behavioral conflicts and perceived discrepant beliefs about topics. These scores were also significantly related to questionnaire reports of parent–child conflict. Parent and child questionnaire reports did not significantly differ, yet on the structured interview, parents reported significantly greater levels of perceived conflict and discrepant beliefs relative to child reports. Additionally, structured interview reports of conflict demonstrated incremental validity by relating to child self-reports of delinquent behaviors, when accounting for questionnaire conflict reports. The findings have implications for increasing understanding of the links between parent–child conflict and psychosocial outcomes.

Accumulating evidence suggests that the experience of early life adversity is a risk factor for a range of poor outcomes across development, including poor physical health in adulthood. The biological embedding model of early adversity (Miller, Chen, & Parker, 2011) suggests that early adversity might become embedded within immune cells known as monocytes/macrophages, programming them to be overly aggressive to environmental stimuli and insensitive to inhibitory signals, creating a “proinflammatory phenotype” that increases vulnerability to chronic diseases across the life span. We tested this hypothesis in the present study. Adolescent girls (n = 147) had blood drawn every 6 months across a 2.5-year period. To assess inflammatory responses to challenge, their monocytes were stimulated in vitro with a bacterial product, and production of the cytokine interleukin-6 was quantified. Hydrocortisone was added to cultures to assess the cells’ sensitivity to glucocorticoids’ anti-inflammatory signal. Using cluster analyses, we found that early life adversity was associated with greater odds of displaying a proinflammatory phenotype characterized by relatively larger interleukin-6 responses and relatively less sensitivity to glucocorticoids. In contrast, ongoing social stress was not associated with increasing odds of being categorized in the proinflammatory cluster. These findings suggest that early life adversity increases the probability of developing a proinflammatory phenotype, which, if sustained, could forecast risk for health problems later in life.

The issue of informant discrepancies about child and adolescent functioning is an important concern for clinicians, developmental psychologists, and others who must consider ways of handling discrepant reports of information, but reasons for discrepancies in reports have been poorly understood. Adolescent attachment and informant depressive symptoms were examined as two explanations for absolute and directional discrepancies about adolescent symptoms, relationships, and social behavior in a sample of 189 eleventh-grade students (mean age = 16.5 years). Adolescent attachment predicted absolute discrepancies, with greater attachment coherence associated with fewer discrepancies in reports of adolescent depressive symptoms, parentadolescent conflict, and adolescent externalizing behavior. Parents' but not adolescents' depressive symptoms sometimes predicted absolute discrepancies. Mothers' depressive symptoms and adolescent attachment predicted the direction of discrepancies for mother-peer reports only.Many important insights about child and adolescent development have come from studies using informants' reports, and it is widely accepted that a strong research design involves the use of multiple reporters and multiple methods (Achenbach, 2006;Achenbach, McConaughy, & Howell, 1987;Holmbeck, Li, Schurman, Friedman, & Coakley, 2002). Yet multiple reporters bring with them multiple viewpoints, and discrepant reports often emerge. One aspect of child and adolescent functioning -psychological symptoms -has been the focus of a large body of research that has examined the extent to which different reporters agree. This research has been conducted largely by clinical researchers who rely on informant reports of symptoms for diagnosis and treatment decisions as well as to draw conclusions about treatment effectiveness (Achenbach et al., 1987). De Los Reyes and Kazdin (2005) reviewed this research and noted that the clearest point of convergence across studies is that reporters typically do not agree about child and adolescent symptomatology. Reporter discrepancies such as these are troubling for both researchers and clinicians because their conclusions about treatment or research outcomes may vary considerably depending on which informants' information is used (e.g., Kazdin, 1989).Despite the fact that the driving force behind previous investigations of reporter discrepancies has been clinical research with a sole focus on different reports of child and Correspondence concerning this article should be addressed to Katherine B.

Despite widespread interest in examining the role of conflict for adolescent development, researchers only rarely have examined adolescents’ experiences of conflict across relationships. The present study examined how adolescents’ experiences of conflict with parents and friends were linked to their social functioning. Adolescents (n = 189) and their mothers and fathers participated in semi-structured discussions about areas of adolescent-parent conflict in the laboratory. In addition, adolescents reported about conflict in their best friendships, and peers reported about adolescents’ social acceptance and behavior in social settings. Parent-adolescent conflict was associated with peer-reported aggression and delinquency, and friendship conflict was associated with delinquency and prosocial behavior. In addition, significant Parent-Adolescent Conflict × Friend-Adolescent Conflict interactions revealed that parent-adolescent conflict was associated with poor social functioning only when conflict with best friends was also high. The findings suggest that consideration of conflict across relationships may yield insight into the specific contexts in which conflict is associated with negative outcomes for adolescents.
