Linking post-stressor interpersonal processes in adolescent girls' close friendships with acute HPA stress responses.

Introduction: For adolescent girls, close friendships may facilitate stress management and mitigate risk for internalizing psychopathology. However, little is known about how friendship processes may buffer (or potentially exacerbate) acute psychobiological responses to interpersonal stressors in ways that affect risk.

Methods: In a sample of 220 girls (ages 12-17 years) with a history of internalizing symptoms, this study investigated friendship dynamics following the Trier Social Stress Test (TSST) to evaluate associations between post-stressor friendship behaviors (expressions of vulnerability by the stressed teen; support offered by their close friend) and hypothalamic-pituitary-adrenal (HPA) axis stress responses.

Interpersonal life stress, inflammation, and depression in adolescence: Testing Social Signal Transduction Theory of Depression.

Background: Depression rates increase markedly for girls across the adolescent transition, but the social-environmental and biological processes underlying this phenomenon remain unclear. To address this issue, we tested a key hypothesis from Social Signal Transduction Theory of Depression, which posits that individuals who mount stronger inflammatory responses to social stress should exhibit greater increases in depressive symptoms following interpersonal life stress exposure than those who mount weaker inflammatory responses to such stress.

Method: Participants were 116 adolescent girls (M  = 14.

Interpersonal Stress Severity Longitudinally Predicts Adolescent Girls' Depressive Symptoms: the Moderating Role of Subjective and HPA Axis Stress Responses.

In recent decades, stress response models of adolescent depression have gained attention, but it remains unclear why only certain adolescents are vulnerable to the depressogenic effects of stress while others are not. Building on evidence that affective and physiological responses to stress moderate the impact of stress exposure on depression, the current study examined whether the interaction between severity of interpersonal stress, subjective affective reactivity, and hypothalamic-pituitary-adrenal (HPA) axis reactivity to an acute, in-vivo psychosocial stressor prospectively predicted depressive symptoms nine months later. Hypotheses were examined with a clinically-oversampled group of 182 adolescent girls (aged 12-16) to ensure an examination of the widest possible range of risk.

Exploring knowledge and perceptions of palliative care to inform integration of palliative care education into cystic fibrosis care.

Background: Individuals with cystic fibrosis (CF) face the challenges of managing a chronic, progressive disease. While palliative care is a standard of care in serious illnesses, there are no guidelines for its incorporation into CF care. Patients with CF, caregivers, and CF care providers may lack knowledge about palliative care and perceive barriers to integrated care.

Patient and Provider Perspectives on Communication About Body Image With Adolescents and Young Adults With Cystic Fibrosis.

Objective: This mixed-methods study examined perspectives of adolescents and young adults (AYAs) with cystic fibrosis (CF) and health care providers on body image communication.

Methods: Interviews and questionnaires were completed by 20 AYAs and 28 providers.

Results: Although 85% of patients reported they had never had a body image conversation with a health care provider, 74% of providers reported discussing this topic with patients.

Adolescent Susceptibility to Peer Influence in Sexual Situations.

Purpose: One consistent predictor of adolescents' engagement in sexual risk behavior is their belief that peers are engaging in similar behavior; however, not all youth are equally susceptible to these peer influence effects. Understanding individual differences in susceptibility to peer influence is critical to identifying adolescents at risk for negative health outcomes. The purpose of this project was to identify predictors of susceptibility to peer influence using a novel performance-based measure of sexual risk taking.

Adolescents misperceive and are influenced by high-status peers' health risk, deviant, and adaptive behavior.

Most peer influence research examines socialization between adolescents and their best friends. Yet, adolescents also are influenced by popular peers, perhaps due to misperceptions of social norms. This research examined the extent to which out-group and in-group adolescents misperceive the frequencies of peers' deviant, health risk, and adaptive behaviors in different reputation-based peer crowds (Study 1) and the prospective associations between perceptions of high-status peers' and adolescents' own substance use over 2.

Friendship quality and health-related outcomes among adolescents with cystic fibrosis.

Objective: During adolescence, the significance of peer relationships peaks, and the presence and quality of dyadic friendships impact psychosocial outcomes. Yet, friendships have been studied infrequently among youth with chronic illness, particularly youth with cystic fibrosis (CF). The current aims were to (1) describe friendships among adolescents with CF, including number, duration, frequency of interactions, and positive/negative friendship qualities, and (2) explore associations between friendship quality, treatment adherence, and health-related quality of life.

Relational victimization, friendship, and adolescents' hypothalamic-pituitary-adrenal axis responses to an in vivo social stressor.

Adolescents' peer experiences may have significant associations with biological stress-response systems, adding to or reducing allostatic load. This study examined relational victimization as a unique contributor to reactive hypothalamic-pituitary-adrenal (HPA) axis responses as well as friendship quality and behavior as factors that may promote HPA recovery following a stressor. A total of 62 adolescents (ages 12-16; 73% female) presenting with a wide range of life stressors and adjustment difficulties completed survey measures of peer victimization and friendship quality.

Intrinsic religiosity buffers the longitudinal effects of peer victimization on adolescent depressive symptoms.

Peer victimization is a common and potentially detrimental experience for many adolescents. However, not all youth who are exposed to peer victimization experience maladaptive outcomes, such as depression. Thus, greater attention to potential moderators of peer victimization is particularly important.

Sexual communication between early adolescents and their dating partners, parents, and best friends.

This study assessed early adolescents' sexual communication with dating partners, parents, and best friends about six sexual health topics: condoms, birth control, sexually transmitted diseases (STDs), human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), pregnancy, and abstinence/waiting. Using a school-based sample of 603 youth (ages 12 to 15; 57% female; 46% Caucasian), we examined communication differences across demographic and developmental factors, tested whether communication with parents and best friends was associated with greater communication with partners, and examined associations between communication and condom use. More than half of participants had not discussed any sexual topics with their dating partners (54%), and many had not communicated with parents (29%) or best friends (25%).

Adolescents' recognition of potential positive and negative outcomes in risky dating situations.

Risky adolescent behavior represents a significant public health concern, with potential detrimental consequences for youth and society in general. Problem behavior theory suggests that engaging in one type of problem behavior increases the likelihood of other problem behaviors. As a result, understanding how youth perceive common dating risk situations that may place them at risk not only for dating violence but also for a variety of other problem behaviors could inform prevention programming.

High peer popularity longitudinally predicts adolescent health risk behavior, or does it?: an examination of linear and quadratic associations.

Objective: In contrast to prior work, recent theory suggests that high, not low, levels of adolescent peer popularity may be associated with health risk behavior. This study examined (a) whether popularity may be uniquely associated with cigarette use, marijuana use, and sexual risk behavior, beyond the predictive effects of aggression; (b) whether the longitudinal association between popularity and health risk behavior may be curvilinear; and (c) gender moderation.

Methods: A total of 336 adolescents, initially in 10-11th grades, reported cigarette use, marijuana use, and number of sexual intercourse partners at two time points 18 months apart.

Problematic situations associated with dating experiences and relationships among urban African American adolescents: a qualitative study.

This qualitative study focused on the identification of problem situations associated with adolescent dating experiences and relationships, including those that placed youth at risk for dating violence perpetration or victimization. Interviews were conducted with 44 African American middle and high school students in an urban school system. Qualitative analysis identified 18 individual themes representing six categories of problem situations: (a) approach and initiation; (b) conflict, conflict resolution, and break-ups; (c) communication, connection, and emotion; (d) aggression and victimization; (e) the role of others; and (f) media and technology.

Associations between Sadness and Anger Regulation Coping, Emotional Expression, and Physical and Relational Aggression among Urban Adolescents.

This study examined associations between self reports of sadness and anger regulation coping, reluctance to express emotion, and physical and relational aggression among two cohorts of predominantly African-American fifth (N = 191; 93 boys and 98 girls) and eighth (N = 167; 73 boys and 94 girls) graders. Multiple regression analyses indicated unique associations between relational aggression and expressive reluctance and sadness regulation coping. In contrast, physical aggression, but not relational aggression, was associated with anger regulation coping.

Core competencies and the prevention of youth violence.

We discuss how the five core competencies for healthy adjustment in adolescence (a positive sense of self, self-control, decision-making skills, a moral system of belief, and prosocial connectedness) are represented in theories of aggression and youth violence. We then discuss research supporting the relation between these core competencies and aggressive and violent behavior in childhood and adolescence. Finally, we address the degree to which these core competencies have been included and systematically evaluated within school-based prevention programs, and we end with suggestions for future directions.
