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.

A social-development model of the evolution of depressive symptoms from age 13 to 30.

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.

RANDOMIZED EVALUATION OF AN INTERVENTION TO ENHANCE A SENSE OF BELONGINGNESS AMONG ENTERING COLLEGE STUDENTS.

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.

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 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.

Adolescent peer struggles predict accelerated epigenetic aging in midlife.

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 ( = 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.

Lifetime marijuana use and epigenetic age acceleration: A 17-year prospective examination.

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.
