This study investigated associations between natural mentoring relationships and academic performance via psychological distress among underrepresented college students attending an elite predominantly White institution (PWI). Specifically, this study explored whether the quantity of natural mentors possessed upon college entry, the retention of natural mentors across the first year of college, and overall changes in the number of natural mentors possessed during the first year of college predicted improvements in students' semester grade point averages (GPAs) via reductions in psychological distress. Participants in this study included 336 first-year undergraduate students attending a selective PWI. Students were eligible to participate in this study if they were first-generation college students, students from economically disadvantaged backgrounds, or students from underrepresented racial/ethnic minority groups. Results of this study indicated that a greater number of retained natural mentoring relationships across the first year of college were associated with improvements in students' GPAs via reductions in symptoms of depression from the Fall to Spring semester. The results of this study suggest that institutional efforts to support the maintenance of preexisting mentoring relationships may be an effective approach to promoting the academic success of underrepresented college students during the first year of college.

Middle adolescents' close friendship strength and the degree to which their broader peer group expressed a preference to affiliate with them were examined as predictors of relative change in depressive symptoms, self-worth, and social anxiety symptoms from ages 15 to 25 using multimethod, longitudinal data from 169 adolescents. Close friendship strength in midadolescence predicted relative increases in self-worth and decreases in anxiety and depressive symptoms by early adulthood. Affiliation preference by the broader peer group, in contrast, predicted higher social anxiety by early adulthood. Results are interpreted as suggesting that adolescents who prioritize forming close friendships are better situated to manage key social developmental tasks going forward than adolescents who prioritize attaining preference with many others in their peer milieu.

The world of peers presents a unique developmental challenge to adolescents—one that is likely to be linked to prior experiences within the family, affected by concurrent experiences with adults outside the family, and predictive of future mental and physical health. To negotiate relationships with peers successfully, adolescents must manage the challenge of connecting with peers while establishing autonomy regarding peer influences. Both the nature of this challenge and how it is handled are linked closely to the ways adolescents are treated by the adults in their lives. Adolescents’ capacities for autonomy and connection can be developed both in the family and in interventions that engage youth with adults outside the family, suggesting a substantial role for adults in easing adolescents’ peer challenges.

Interview, self-report, peer-report, and observational data were used to examine parent and peer relationship qualities as predictors of relative changes in attachment security in a community sample of adolescents followed from age 14 to 24. Early maternal supportive behavior predicted relative increases in attachment security from adolescence to adulthood, whereas psychological control and interparental hostile conflict predicted relative decreases. Peer predictors of relative increases in security included collaborative and autonomous behaviors and lack of hostile interactions, with peer predictions growing stronger for relationships assessed at later ages. Overall, models accounted for sufficient variance as to suggest that attachment security across this period is well explained by a combination of stability plus theoretically predicted change linked to social relationship qualities.

The potential importance of depending on others during adolescence in order to establish independence in young adulthood was examined across adolescence to emerging adulthood. Participants included 184 teens (46% male; 42% non-White), their mothers, best friends, and romantic partners, assessed at ages 13–14, 18, 21–22, and 25. Path analyses showed that associations were both partner and age specific: markers of independence were predicted by participants’ efforts to seek support from mothers at age 13, best friends at 18, and romantic partners at 21. Importantly, analyses controlled for support seeking from these partners at other ages, as well as for other potentially confounding variables including attachment security, scholastic/job competence, and physical attractiveness over time. Moreover, analyses suggested the transfer of support seeking behavior from mothers to best friends to romantic partners over time based on support given by the previous partner at an earlier age.
