Personal mental health treatment stigma, perceived caregiver and peer treatment stigma, and help-seeking behaviors among adolescents
Neurocognitive outcomes in adolescents with and without four weeks of cannabis abstinence: A randomized clinical trial using contingency management
Brief cannabis abstinence may be associated with improvements in executive function among adolescents, supporting the idea of neurocognitive recovery, which has important implications for treatment, prevention, and public health policies
Support-seeking about social relationships with friends is associated with friendship quality, emotional support, and self-disclosure in adolescence
Adolescent friendships offer a crucial context for learning to seek social support. Through repeated social support encounters, adolescents take in social information and shape their own development. The current study characterizes adolescents' support-seeking discussion topics with close friends, how the topics are influenced by adolescent age and gender, and how they are related to interpersonal processes in close friendships. A community sampl…
Adolescent responses to paternal verbal aggression: Assessing spillover and compensatory processes using random intercept cross‐lagged panel models
INTRODUCTION: Prior research suggests several pathways through which verbal aggression manifests across adolescent relationship contexts, including spillover (continuity of aggression across different relationships) and compensation (offsetting an aggressive relationship with less aggression in other relationships). These pathways vary across timescales in ways that between-person analytic approaches are unlikely to adequately capture. The curren…
Empathy across three generations: From maternal and peer support in adolescence to adult parenting and child outcomes
This study examined the development of empathic care across three generations in a sample of 184 adolescents in the United States (99 female, 85 male; 58% White, 29% African American, 8% mixed race/ethnicity, 5% other groups), followed from their family of origin at age 13 into their parenting years (through their mid-30s). Mothers' empathic support toward adolescents at age 13 predicted teens' empathy for close friends across adolescence (13–19 …
Adolescent social learning within supportive friendships: Self‐ disclosure and relationship quality from adolescence to adulthood
This study examines links between self-disclosure and relationship quality with close friends from adolescence to adulthood. A diverse community sample of adolescents (N = 184) participated in survey and observational measures annually from ages 13 through 29, along with their close friends and romantic partners. Random intercept cross-lagged panel modeling (RICLPM) was used to parse markers of within-individual change from age 13 to 18. Long-ter…
Vulnerable self-disclosure co-develops in adolescent friendships: Developmental foundations of emotional intimacy
This study examines the development of vulnerable self-disclosure in supportive interactions from ages 13 to 29. A diverse community sample ( N = 184; 85 boys 99 girls; 58% white, 29% Black, 13% other identity groups) participated in annual observed interactions with close friends and romantic partners. Participants were observed as they sought and provided support to their best friends each year from age 13 to 18, and as they sought support from…
You-talk in young adult couples' conflict: Family-of-origin roots and adult relational aggression sequelae
The present study examines greater use of the word "you" (i.e., you-talk) during couple's conflict as linked to conflict behaviors and relational aggression. The way couples navigate relationship conflict is a key risk factor for relational aggression, and investigating conflict microprocesses can inform intervention efforts. In this study, 184 target participants (86 men, 98 women; 58% White, 29% African American, 8% mixed race/ethnicity, 5% oth…
Adolescent caregiving success as a predictor of social functioning from ages 13 to 33
Adolescent success providing satisfying support in response to a close friend's call in a caregiving task was examined as a potentially fundamental developmental competence likely to predict future social functioning, adult caregiving security, and physical health. Adolescents (86 males, 98 females; 58% White, 29% African American, 8% mixed race/ethnicity, 5% other) were followed from ages 13 to 33 (1998–2021) using multiple methods and reporters…
Social Regulation of the Neural Threat Response Predicts Subsequent Markers of Physical Health
OBJECTIVE: Social support has been linked to a vast range of beneficial health outcomes. However, the physiological mechanisms of social support are not well characterized. Drawing on functional magnetic resonance imaging and health-related outcome data, this study aimed to understand how neural measures of "yielding"-the reduction of brain activity during social support-moderate the link between social support and health. METHODS: We used a data…
When friendships surpass parental relationships as predictors of long-term outcomes: Adolescent relationship qualities and adult psychosocial functioning
Perceptions of adolescent–parent and adolescent–peer relationship qualities, and adolescents’ attachment states of mind were examined as predictors of adult social and romantic relationship quality, depressive symptoms, and work performance. Adolescents (86 male, 98 female; 58% White, 29% African American, 8% mixed race/ethnicity, 5% other groups) were followed from age 13 to 24 via observational, self-, parent-, and close friend-reports. Adolesc…
Characterizing Emotional Support Development: From Adolescent Best Friendships to Young Adult Romantic Relationships
This study examined development of emotional support competence within close friendships across adolescence. A sample of 184 adolescents (53% girls, 47% boys; 58% White, 29% Black, 14% other identity groups) participated in seven waves of multimethod assessments with their best friends and romantic partners from age 13 to 24. Latent change score models identified coupled predictions over time from emotional support competence to increasing friend…
Facilitating connection to enhance college student well‐being: Evaluation of an experiential group program
This randomized controlled trial examined the impact of The Connection Project , an experiential, relationship‐focused intervention designed to improve school belongingness and decrease symptoms of depression and loneliness among new college students. Participants were 438 first‐year and transfer students (232 treatment, 206 waitlist‐control) at a medium‐sized, 4years, predominantly White public university in the Southeastern United States. At po…
Here for You: Attachment and the Growth of Empathic Support for Friends in Adolescence
Attachment was examined as a predictor of teens’ empathic support for friends in a multimethod longitudinal study of 184 U.S. adolescents (58% Caucasian, 29% African American, 13% other) followed from ages 14 to 18. Adolescents’ secure state of mind regarding attachment at 14 predicted teens’ greater capacity to provide empathic support during observed interactions with friends across ages 16–18 (Baverage = .39). Teens’ empathic support was gener…
Perceived Psychological Control in Early Adolescence Predicts Lower Levels of Adaptation into Mid-Adulthood
This study examined perceived parental psychological control in early adolescence as a critical stressor likely to be associated with lower levels of adaptation into mid-adulthood. A diverse sample of 184 adolescents was followed from age 13 through 32 to assess predictions to adult adaptation. Perceived parental psychological control at age 13 predicted relative decreases in observed support, lower likelihood of being in a romantic relationship,…
Autonomy and relatedness in early adolescent friendships as predictors of short‐ and long‐term academic success
This study examined early adolescent autonomy and relatedness during disagreements with friends as key social competencies likely to predict academic achievement during the transition to high school and academic attainment into early adulthood. A sample of 184 adolescents was followed through age 29 to assess predictions to academic success from observed autonomy and relatedness during a disagreement task with a close friend. Observed autonomy an…
The Intensity Effect in Adolescent Close Friendships: Implications for Aggressive and Depressive Symptomatology
This study examined the effect of close friendship intensity as a potential amplifier of an adolescent's preexisting tendencies toward depressive and aggressive symptoms. A diverse community sample of 170 adolescents and their closest friends was assessed via multiple methods, and adolescents were followed from age 16 to 17. Results supported the hypothesized effect, with more intense close friendships interacting with higher baseline levels of b…
