RESUMO
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-term longitudinal path models also investigated cascading associations among self-disclosure and relationship quality, on aggregate, from adolescence to adulthood. Adolescents who reported a higher-quality friendship in a given year demonstrated greater-than-expected increases in self-disclosure the following year, and an adolescent demonstrated high self-disclosure one year reported greater-than-expected increases in friendship quality the following year. Higher mean self-disclosure in adolescence predicted higher mean self-disclosure in adulthood. Results are interpreted as identifying high-quality adolescent friendships as key contexts for developing intimacy-building capacities (i.e. self-disclosure), which sets the stage for satisfying close relationships in adulthood.
RESUMO
This study examined struggles to establish autonomy and relatedness with peers in adolescence and early adulthood as predictors of advanced epigenetic aging assessed at age 30. Participants (N = 154; 67 male and 87 female) were observed repeatedly, along with close friends and romantic partners, from ages 13 through 29. Observed difficulty establishing close friendships characterized by mutual autonomy and relatedness from ages 13 to 18, an interview-assessed attachment state of mind lacking autonomy and valuing of attachment at 24, and self-reported difficulties in social integration across adolescence and adulthood were all linked to greater epigenetic age at 30, after accounting for chronological age, gender, race, and income. Analyses assessing the unique and combined effects of these factors, along with lifetime history of cigarette smoking, indicated that each of these factors, except for adult social integration, contributed uniquely to explaining epigenetic age acceleration. Results are interpreted as evidence that the adolescent preoccupation with peer relationships may be highly functional given the relevance of such relationships to long-term physical outcomes.

This 17-year prospective study applied a social-development lens to the challenge of identifying long-term predictors of adult depressive symptoms. A diverse community sample of 171 individuals was repeatedly assessed from age 13 to age 30 using self-, parent-, and peer-report methods. As hypothesized, competence in establishing close friendships beginning in adolescence had a substantial long-term predictive relation to adult depressive symptoms at ages 27-30, even after accounting for prior depressive, anxiety, and externalizing symptoms. Intervening relationship difficulties at ages 23-26 were identified as part of pathways to depressive symptoms in the late twenties. Somewhat distinct paths by gender were also identified, but in all cases were consistent with an overall role of relationship difficulties in predicting long-term depressive symptoms. Implications both for early identification of risk as well as for potential preventive interventions are discussed.
RESUMO
This study examined an intervention designed to improve sense of belongingness for new students at a medium-sized, four-year, public university in the Eastern United States. A randomized controlled trial was used to assess the impact of The Connection Project, a novel, 9-session intervention in a sample of 128 first-year students (77 treatment, 48 waitlist control). Given the onset of COVID-19, students received a hybrid in-person/online intervention. At post-intervention, the intervention group reported a significantly higher sense of school belongingness, after accounting for baseline levels, than control group students. Post-hoc analyses of moderation by demographic variables indicate that the intervention functioned similarly for students from a variety of backgrounds in this sample. These results are interpreted as suggesting the potential value of this intervention to promote a sense of community and connection among new students in college, whether delivered in-person or online.
RESUMO
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 postintervention, the treatment group reported significant relative increases in school belonging and significant relative reductions in levels of loneliness and depressive symptoms in comparison to waitlist-controls. Program effects were stronger for students from marginalized racial or ethnic backgrounds, students from lower socioeconomic status households, and transfer students. Results are interpreted as suggesting the utility of experiential, peer-support prevention programming to promote college students' well-being, particularly college students who hold identities that are traditionally disadvantaged in this context.

AIMS: This study was designed to assess links between lifetime levels of marijuana use and accelerated epigenetic aging. DESIGN: Prospective longitudinal study, following participants annually from age 13 to age 30. SETTING AND PARTICIPANTS: A community sample of 154 participants recruited from a small city in the Southeastern United States. MEASUREMENTS: Participants completed annual assessments of marijuana use from age 13 to age 29 and provided blood samples that yielded two indices of epigenetic aging (DNAmGrimAge and DunedinPoAm) at age 30. Additional covariates examined included history of cigarette smoking, anxiety and depressive symptoms, childhood illness, gender, adolescent-era family income, and racial/ethnic minority status. FINDINGS: Lifetime marijuana use predicted accelerated epigenetic aging, with effects remaining even after covarying cell counts, demographic factors and chronological age (ß's = 0.32 & 0.27, p's < 0.001, 95% CI's = 0.21-0.43 & 0.16-0.39 for DNAmGrimAge and DunedinPoAm, respectively). Predictions remained after accounting for cigarette smoking (ß's = 0.25 & 0.21, respectively, p's < 0.001, 95% CI's = 0.14-0.37 & 0.09-0.32 for DNAmGrimAge and DunedinPoAm, respectively). A dose-response effect was observed and there was also evidence that effects were dependent upon recency of use. Effects of marijuana use appeared to be fully mediated by hypomethylation of a site linked to effects of hydrocarbon inhalation (cg05575921). CONCLUSIONS: Marijuana use predicted epigenetic changes linked to accelerated aging, with evidence suggesting that effects may be primarily due to hydrocarbon inhalation among marijuana smokers. Further research is warranted to explore mechanisms underlying this linkage.
