Abstract
BACKGROUND Research suggests that most mental health conditions have their onset in the critically social period of adolescence. Yet, we lack understanding of the potential social processes underlying early psychopathological development. We propose a conceptual model where daily-life social interactions and social skills form an intermediate link between known risk and protective factors (adverse childhood experiences, bullying, social support, maladaptive parenting) and psychopathology in adolescents - that is explored using cross-sectional data. METHODS N = 1913 Flemish adolescent participants (Mean age = 13.8; 63% girls) were assessed as part of the SIGMA study, a large-scale, accelerated longitudinal study of adolescent mental health and development. Self-report questionnaires (on risk/protective factors, social skills, and psychopathology) were completed during class time; daily-life social interactions were measured during a subsequent six-day experience-sampling period. RESULTS Registered uncorrected multilevel linear regression results revealed significant associations between all risk/protective factors and psychopathology, between all risk/protective factors and social processes, and between all social processes and psychopathology. Social processes (social skills, quantity/quality of daily social interactions) were uniquely predicted by each risk/protective factor and were uniquely associated with both general and specific types of psychopathology. For older participants, some relationships between social processes and psychopathology were stronger. CONCLUSIONS Unique associations between risk/protective factors and psychopathology signify the distinct relevance of these factors for youth mental health, whereas the broad associations with social processes support these processes as broad correlates. Results align with the idea of a social pathway toward early psychopathology, although follow-up longitudinal research is required to verify any mediation effect.

Psychol Res Behav Manag 2024; 17:3611-3623. [PMID: 39435368 PMCID: PMC11492902 DOI: 10.2147/prbm.s474339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2024] [Accepted: 10/13/2024] [Indexed: 10/23/2024] Open
Abstract
Background Positive parent-teen and peer relationships are crucial support resources for adolescents with type 1 diabetes mellitus (T1DM). There is quite a bit of research on parent-teen relationships in Western countries, less so with peer relationships. Additionally, information on these relationships and their influencing factors among adolescents from other regions with different family culture and peer cohesion is limited, which impedes the development of targeted interventions. Methods This study analyzed baseline data from a randomized controlled trial in China involving 122 adolescents with T1DM aged 12-18 years. Data were collected using established questionnaires on social-demographic and clinical characteristics, perceived stress, general self-efficacy, coping styles, diabetes self-management, and parent-teen and peer relationships. Multivariate linear regression analysis was conducted to determine the associating factors of parent-teen relationships and peer relationships respectively. Results The total score of the parent-teen relationships subscale was 11.02 ± 2.77, within a theoretical range of 4-16. The total score of the peer relationships subscale was 16.51 ± 2.42, within a theoretical range of 5-20. Positive coping styles, less negative coping styles, and more collaboration with parents in diabetes self-management were associated with better parent-teen relationships. Younger age, positive coping styles, less negative coping styles, and higher goals for diabetes self-management were associated with better peer relationships. Conclusion There is room to improve parent-teen relationships, maybe via encouraging more collaboration between parents and adolescents for diabetes management. The coping styles training is indicated to improve both relationships.

Abstract
Adolescent residential mobility can be a stressful life event, potentially aggravating internalizing or externalizing problems. However, the longitudinal effects of residential mobility are understudied and may be context-dependent. This study investigates the longitudinal associations between adolescent residential mobility and internalizing and externalizing problems. Additionally, this study examines for whom residential moves are most detrimental by including subjective moving experience, gender, and friendship quality before the move as moderators. Longitudinal data from 2,029 adolescents (51% female) from the TRacking Adolescents' Individual Lives Survey (TRAILS) were used (Mage [SD] at T1 = 11.1 [0.55], T2 = 13.6 [0.52], and T3 = 16.3 [0.70]). Results from stepwise multi-level random-effect models showed that adolescents who experienced an unpleasant move remained stable in internalizing problems, while others decreased over time. Adolescents who moved increased stronger in externalizing problems than adolescents who did not move, independent of whether they experienced the move as unpleasant. Gender and friendship quality before the move did not moderate the relation between residential mobility and internalizing or externalizing problem development. These results emphasize that residential moves in adolescence, especially when experienced as unpleasant, can have long-lasting negative effects on adolescent development.

Abstract
Friendship is critical for individuals' well-being, but recent efforts to characterize Americans' friendship have suggested that these relationships are in peril. The present study is a report on the methods and results of three surveys from the American Friendship Project (AFP). The goal of the AFP is to be the most accurate and most complete account of American friendship as well as its health and change over time. The AFP reports on five critical facets of social health as it relates to friendship: 1) the structural factors of friendship (e.g., who are they, how many); 2) friendship quality (e.g., satisfaction, closeness); 3) social support from friends; 4) the quantity of online and offline communication; and 5) well-being (e.g., life satisfaction, loneliness, connection). Data was collected from two national samples of American adults in 2022 and 2023 and from a large sample of college students across three universities in 2022. The key finding from this investigation is, compared to the discouraging results of other recent surveys, Americans reported having more friends and fewer were friendless. AFP results also suggest that face-to-face (FtF) meetings among friends are quite common, as are telephone calls and text messaging. College student and adult samples reported very similar attitudes and experiences with friendship overall, but students were more likely to meet friends at school and to keep them for a shorter length of time. Another key finding is Americans long for greater closeness with friends; though over 75% were satisfied with the number of friends they had, over 40% felt they were not as close to their friends as they would like. Overall, the AFP is a rich source of data that can be used to answer a multitude of questions about friendship and its connection to well-being.

Abstract
BACKGROUND Adolescents with rare genetic disorders represent a population that can be at risk in psychosocial terms. Despite its importance, the association of autism traits and social withdrawal in behavioral and emotional problems in adolescents with rare genetic disorders remains understudied. AIM The study aimed to empirically examine the clinical characteristics of adolescents with rare genetic disorders with a behavior theory-driven approach. METHOD We investigated the behavioral and emotional problems and current and lifetime autistic traits in a sample of 93 Norwegian adolescents (Mage = 13.2 years, SDage = 2.4, rangeage 10-17, 62.4% females, 37.6% males) with various rare genetic disorders. The adolescents were investigated cross-sectionally utilizing standardized psychometric questionnaires rated by their parents. RESULTS More current and lifetime autistic traits and social withdrawal were all associated with more internalizing problems. Further analyses demonstrated that social withdrawal partially mediated the positive association between current autistic traits and internalizing problems. In contrast, social withdrawal fully mediated the positive association between lifetime autistic traits and internalizing problems. CONCLUSION AND IMPLICATIONS Our results demonstrate important characteristics of adolescents with rare genetic disorders that may guide clinicians and future interventions. Social withdrawal may be prodromal to internalizing problems such as anxiety and depression. Thus, clinically addressing social withdrawal can represent a means to prevent internalizing problems in adolescents with rare genetic disorders and autistic traits.

Abstract
OBJECTIVE Internalizing and externalizing problems predict poor academic and social outcomes. However, ADHD co-occurs with internalizing and externalizing problems and is itself a risk factor, thus preventing precise inferences. This study evaluated childhood anxiety, depression, and aggression as predictors of change in adolescent academic and social outcomes, including moderation by childhood ADHD. METHODS 182 ethnically-diverse 5- to 11-year-old youth with (54.7%) and without (45.3%) ADHD completed a separate baseline and 6- to 7-year prospective follow-up assessment, consisting of parallel measures across youth psychopathology, academic functioning (i.e., academic achievement, school competence), and friendship quality domains. RESULTS Whereas childhood ADHD inversely predicted academic competence, depression and aggression uniquely predicted worsening friendship quality. Interestingly, anxiety was unrelated to change in academic and friendship outcomes; similarly, neither ADHD, depression, nor aggression predicted change in objectively-measured academic achievement from a standardized assessment. CONCLUSION Implications for intervention and prevention are considered, including school-based approaches, within a developmental psychopathology framework.

Abstract
BACKGROUND During adolescence, peer support has an increasingly important role in identity formation and well-being. Prior research has identified that lack of social support from peers in adolescence is a potent risk factor for depression. Two ways that social support has been operationalized is by the number of one's friends (i.e., 'quantity') and perception of one's network (i.e., 'quality'). Typically, these aspects of peer support are assessed separately. METHODS Using data from the National Longitudinal Study of Adolescent to Adult Health (N = 3,857), this study sought to test whether (1) adolescent depression relates to having fewer friends versus lower quality friendships, (2) these aspects of adolescent peer support prospectively predict depression in adulthood, (3) gender moderates the effects of peer support on depression, and (4) these aspects of peer support buffer the effects of stressful life events on depression. RESULTS Peer support quality uniquely predicted depression in adolescence and adulthood among both males and females. The effect of peer support quality on depressive symptoms, however, was greater for females than males. By contrast, peer support quantity did not uniquely predict depression for males or females. CONCLUSIONS Qualitative aspects of adolescent peer support uniquely contribute to mental health not only in adolescence, but in adulthood as well. Potential processes through which peer support relates to depression are discussed, as well as implications for treatment.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic has had a profound impact on the mental health and well-being of adolescents. This study aimed to investigate the development of health-related quality of life (HRQoL) and mental health among adolescents in Northern Italy by comparing cross-sectional surveys conducted in 2021 and 2022, with a particular focus on the influence of age and gender. The sample included adolescents aged 11-19 years from public schools in South Tyrol. Validated psychometric instruments were used to assess HRQoL, anxiety and depression symptoms, and psychosomatic complaints. Sociodemographic variables, COVID-19 burden, and pandemic-related factors were measured. Statistical analyses included chi-square tests, correlation coefficients, and logistic regression analyses. The results indicated that while the self-reported burden of adolescents decreased significantly in 2022 (n = 1885) compared to 2021 (n = 1760), there were no significant differences in symptoms of anxiety, depressive symptoms, low HRQoL, and increased psychosomatic complaints between the two surveys for both early and late adolescents. Females consistently had higher percentages for all outcome variables, and symptoms of anxiety increased with age in females, but not in males. Both genders experienced an increase in depressive symptoms and low HRQoL with age. The co-occurrence of mental health outcomes was observed, suggesting overlapping patterns among anxiety, depression, low HRQoL, and psychosomatic complaints. These findings underscore the intricate relationship between age, gender, and mental health outcomes among adolescents during the pandemic. It is important to recognize that late adolescents may exhibit distinct vulnerabilities and may require tailored support approaches to address their specific mental health challenges, differing from those needed for early adolescents.

Abstract
This meta-analysis examined concurrent associations between aggression, withdrawal, assertion, and prosocial behavior and each of positive and negative friendship quality across studies with 22,657 children and adolescents (Mage = 11.71 years; 51.7% girls; 67.7% White). Studies were published between 1995 to 2021 and 32.4% were conducted outside of North America. Aggression was linked to more negative, r ¯ = .19, 95% CI [.14, .24], and less positive, r ¯ = -.05 [-.08, -.01], friendships. Withdrawal was associated with less positive friendships, r ¯ = -.13 [-.18, -.08], whereas prosocial behavior was related to more positive, r ¯ = .29 [.22, .37], as well as less negative, r ¯ = -.16 [-.20, -.12], friendships. Assertion was related to more positive friendships, r ¯ = .15 [.01, .28].
