Stability in social networks.

Dunbar's number is the cognitive limit of human beings to maintain stable relationships with other individuals in their social networks, and it is found to be 150. It is based on the neocortex size of humans. Usually, Dunbar's number and related phenomena are studied from the perspective of an individual. Dunbar's number also plays a crucial role in evolutionary psychology and allied areas. However, no study done so far has considered a couple who are in a stable relationship as a system from the perspective of Dunbar's number and its hierarchy layers. In this paper, we study the impact of Dunbar's number and Dunbar's hierarchy from the perspective of a couple by studying mathematically the conjoint Dunbar graphs for a couple. The cost of romance is the loss of almost two people from one's support network when a human being enters into a new relationship. Thus, we obtain mathematically that there is no significant change in one's friendship if human beings spend negligible time with their partners. Also, along with marriage and friendship development, we attempt to assess how a person's social network structure holds up over the course of a romantic relationship. The stability of personal social networks is discussed through soft set theory and balance theoretic approach.

Friendship Bench Intervention to Address Depression and Improve HIV Care Engagement Among Adolescents Living with HIV in Malawi: Study Protocol for a Pilot Randomized Controlled Trial.

Background: Adolescents in Sub-Saharan Africa are disproportionately affected by the HIV epidemic. Comorbid depression is prevalent among adolescents living with HIV (ALWH) and poses numerous challenges to HIV care engagement and retainment. We present a pilot trial designed to investigate feasibility, fidelity, and acceptability of an adapted and an enhanced Friendship Bench intervention (henceforth: AFB and EFB) in reducing depression and improving engagement in HIV care among ALWH in Malawi. Methods: Design:: Participants will be randomized to one of three conditions: the Friendship Bench intervention adapted for ALWH (AFB, n=35), the Friendship Bench intervention enhanced with peer support (EFB, n=35), or standard of care (SOC, n=35). Recruitment is planned for early 2024 in four clinics in Malawi.Participants:: Eligibility criteria (1) aged 13-19; (2) diagnosed with HIV (vertically or horizontally); (3) scored ≥ 13 on the self-reported Beck's Depression Inventory (BDI-II); (4) living in the clinic's catchment area with intention to remain for at least 1 year; and (5) willing to provide informed consent.Interventions:: AFB includes 6 counseling sessions facilitated by young, trained non-professional counselors. EFB consists of AFB plus integration of peer support group sessions to facilitate engagement in HIV care. SOC for mental health in public facilities in Malawi includes options for basic supportive counseling, medication, referral to mental health clinics or psychiatric units at tertiary care hospitals for more severe cases.Outcomes:: The primary outcomes are feasibility, acceptability, and fidelity of the AFB and EFB assessed at 6 months and 12 months and compared across 3 arms. The secondary outcome is to assess preliminary effectiveness of the interventions in reducing depressive symptoms and improving HIV viral suppression at 6 months and 12 months. Discussion: This pilot study will provide insights into youth-friendly adaptations of the Friendship Bench model for ALWH in Malawi and the value of adding group peer support for HIV care engagement. The information gathered in this study will lead to a R01 application to test our adapted intervention in a large-scale cluster randomized controlled trial to improve depression and engagement in HIV care among ALWH.

Qualities of Older Adults' Family and Friendship Relationships and Their Association with Life Satisfaction.

While family and friendship relationship qualities are associated with life satisfaction, evidence on how these types of relationships interact to contribute to older adults' life satisfaction is sparse. This study examined how family and friendship relationship qualities may be supportive of (compensatory) or conflict with (competing) older adults' life satisfaction. We adopted a cross-sectional design to analyze data from the Health and Retirement Study (n = 1178, females = 54.8%, mean age = 67.9 years, SD = 9.3 years) to examine compensatory (as in social support) and competing (as in social strain) qualities of family and friendship social relationships and their association with life satisfaction in older adults. For greater explanatory power, we also controlled for life satisfaction by sociodemographic variables of age, gender, education, self-reported general health, physical health and activity, depression, and personality traits. Our findings indicate that the spouse/partner support relationship contributes to older adults' life satisfaction overall and is associated with greater social support and less social strain. Friendship support is associated with improved life satisfaction for older adults reporting spouse/partner strain. Relationship support for the life satisfaction of older adults should consider their need for social support from their social network while minimizing the risk of social strain from adversarial relationships in life situations.

Understanding experiences of 'Gig Buddies': A befriending scheme for people with intellectual disabilities.

BACKGROUND: Research into befriending for people with intellectual disabilities is limited. This study aimed to explore the impact, mechanisms of change, and limitations of a befriending scheme for adults with intellectual disabilities and/or autism. METHODS: Participants were recruited using convenience sampling. Thirteen individuals with intellectual disabilities and/or autism were interviewed and data thematically analysed. RESULTS: Four themes were generated: 'Something fun for me'; 'A good connection'; 'Increasing independence'; and 'A life less quiet'. Befriending had direct benefits through the activities undertaken and the befriending relationships themselves being fun and reducing isolation. Befriending facilitated belonging, improved access to mainstream activities, and fostered independence by providing safety and support. The importance of shared interests and external support for the relationship was highlighted. CONCLUSIONS: Positive outcomes of befriending were found, supporting existing literature and revealing new information from the voices of participants with intellectual disabilities themselves.

Friendship in Autism Spectrum Disorder Is Related to Diverse Developmental Changes Between Toddlerhood and Adolescence.

PURPOSE: Follow-up studies of children diagnosed with autism spectrum disorder (ASD) in early childhood that focus on friendship formation during adolescence are scarce. The present study focused on exploring characteristics possibly related to the ability to establish friendships during adolescence among children diagnosed with ASD in toddlerhood. METHODS: The cohort included 43 participants who underwent comprehensive assessments during toddlerhood and adolescence. Participants were divided into two groups [Friendship(+)/Friendship(-)] based on (1) adolescent social insight as assessed by professionals and (2) parental and adolescent self-reports regarding having or not having friends. No differences in IQ, ASD symptoms, or adaptive behavior during early childhood were found between the two groups. RESULTS: Different and better changes in social communication, adaptive socialization, and daily living skills were observed for the Friendship(+) group. Adolescents with ASD in the Friendship(+) group exhibited greater social independence. Attention-deficit/hyperactivity disorder incidence, anxiety symptom severity, and placement in mainstream or special education classes did not differ between the two groups. CONCLUSION: This long-term study highlights that for children with ASD, longitudinal growth in social communication and adaptive functioning is possible, highly important for and related to the development of the complex ability to establish friendship.

Personality heterophily and friendship as drivers for successful cooperation.

Cooperation is widespread and arguably a pivotal evolutionary force in maintaining animal societies. Yet, proximately, what underlying motivators drive individuals to cooperate remains relatively unclear. Since 'free-riders' can exploit the benefits by cheating, selecting the right partner is paramount. Such decision rules need not be based on complex calculations and can be driven by cognitively less-demanding mechanisms, like social relationships (e.g. kinship, non-kin friendships, dyadic tolerance), social status (e.g. dominance hierarchies) and personalities (social and non-social traits); however, holistic evidence related to those mechanisms is scarce. Using the classical 'loose-string paradigm', we tested cooperative tendencies of a hierarchical primate, the long-tailed macaque (Macaca fascicularis). We studied three groups (n = 21) in their social settings, allowing partner choice. We supplemented cooperation with observational and experimental data on social relationships, dominance hierarchies and personality. Friendship and dissimilarities in non-social 'exploration' and 'activity-sociability' personality traits predicted the likelihood of cooperative dyad formation. Furthermore, the magnitude of cooperative success was positively associated with friendship, low rank-distance and dissimilarity in the activity-sociability trait. Kinship did not affect cooperation. While some findings align with prior studies, the evidence of (non-social) personality heterophily promoting cooperation may deepen our understanding of the proximate mechanisms and, broadly, the evolution of cooperation.

The CARE System in Its Importance in Dealing with Today's Crises1.

The CARE system is a gift from Mother Nature, we have it in our biological heritage; it enables us humans-as a basic gift-to help each other in a large, life-serving context, and thus also to counterbalance destruction. It is about a basic human ability, linked to typical behaviour, but also about a basic human need for connectedness. In this paper, I would like to show how the CARE system can be activated as a collective attitude. The CARE system is strengthened by positive emotions. We are currently being affected by many crises and this triggers fear. How can we deal with this better? Fear is countered with hope and the associated positive emotions such as joy, awe, kama muta and others. These emotions and feelings can be consciously encouraged and placed alongside the feelings of fear. But also, when we share the feelings of grief with each other, it triggers an attitude of CARE. We can grieve together for the various experiences of loss that we go through-but we can also imagine together how we envisage a future that is worth living for everyone. An attitude in the sense of CARING has been practised in friendship for thousands of years. It would therefore be possible to move away from an attitude of competing and outdoing, to an attitude not only of recognition, care, and solidarity in human interaction, but also in our connection with nature.

Le système CARE (prendre soin) est un cadeau de Mère Nature, nous l'avons dans notre patrimoine biologique ; il nous permet, à nous les humains, en tant que don fondamental, de nous entraider dans un contexte vaste et vital et donc aussi de faire contrepoids à la destruction. Il s'agit d'une capacité humaine fondamentale, liée à un comportement typique, mais aussi du besoin humain fondamental d'être en lien. Dans cet article, j'aimerais montrer comment le système CARE peut être activé en tant qu'attitude collective. Le système CARE est renforcé par des émotions positives. Nous sommes actuellement touchés par de nombreuses crises, ce qui suscite la peur. Comment pouvons­nous mieux gérer cette situation ? La peur est contrée par l'espoir et les émotions positives qui y sont associées telles que la joie, la crainte, kama muta et autres. Ces émotions et ces sentiments peuvent être consciemment encouragés et placés à côté des sentiments de peur. Mais aussi, lorsque nous partageons les sentiments d'affliction les uns avec les autres, cela déclenche une attitude de BIENVEILLANCE. Nous pouvons faire ensemble le deuil dans diverses expériences de perte que nous traversons, mais nous pouvons aussi imaginer ensemble comment nous envisageons un avenir qui vaut la peine d'être vécu pour tous. Une attitude cultivant la BIENVEILLANCE est pratiquée dans l'amitié depuis des milliers d'années. Il serait donc possible de passer d'une attitude de compétition, et qui vise à supplanter, à une attitude non seulement de reconnaissance, d'attention et de solidarité dans l'interaction humaine, mais aussi dans notre relation avec la nature.

El sistema DE CUIDADO es un regalo de la Madre Naturaleza, lo tenemos en nuestra herencia biológica; nos permite a los humanos ­como regalo básico­ ayudarnos unos a otros en un contexto amplio, al servicio de la vida, y así también contrarrestar la destrucción. Se trata de una capacidad humana básica, vinculada al comportamiento típico, pero también de una necesidad humana básica de conexión. En este artículo, me gustaría mostrar cómo el sistema DE CUIDADO puede activarse como una actitud colectiva. El sistema DE CUIDADO se fortalece a través de emociones positivas. Actualmente nos vemos afectados por muchas crisis, y esto desencadena el miedo. ¿Cómo podemos afrontarlo mejor? El miedo se contrarresta con la esperanza y las emociones positivas asociadas, como la alegría, el asombro, el kama muta y otras. Estas emociones y sentimientos pueden fomentarse conscientemente y ocupar un lugar junto al miedo. Pero también, cuando compartimos los sentimientos de dolor con otros, se desencadena una actitud de CUIDADO. Podemos sentir juntos el dolor por las diversas experiencias de pérdida por las que pasamos, pero también podemos imaginar juntos un futuro que merezca la pena vivir para todos. Una actitud en el sentido de CUIDAR se practica en la amistad desde hace miles de años. Por lo tanto, sería posible pasar de una actitud de competencia y superación a una actitud no sólo de reconocimiento, cuidado y solidaridad en la interacción humana, sino también en nuestra conexión con la naturaleza.

The role of academic performance, prosocial behaviour and friendships on adolescents' preferred studying partners: A longitudinal social network analysis.

BACKGROUND: Peers constitute an important developmental context for adolescent academic behaviour providing support and resources to either promote or discourage attitudes and behaviours that contribute to school success. When looking for academic help, students may prefer specific partners based on their social goals regarding academic performance. AIMS: Based on the social goals for wanting to achieve academically (e.g., studying to be with friends, increasing/maintaining their own social status), we examine the extent to which adolescents' selection of preferred academic partners (with whom they would like to study) is driven by peers' academic performance, prosocial behaviour and friendships. Moreover, as high-achieving students play an important role in academic settings, whether they are more likely to prefer to study with similar high-achieving peers and friends was examined. SAMPLE: A total of 537 seventh-grade students from 13 classes over three waves. METHODS: Longitudinal social network analyses (RSiena). RESULTS: Adolescents were more likely to select high achievers, friends and prosocial peers as preferred academic partners. Furthermore, high achievers were more likely to choose other high achievers and friends as preferred academic partners. CONCLUSIONS: Adolescents are likely to prefer as study partners someone they can learn from and who is more approachable, cooperative and friendly. Regarding high achievers, they would choose not only academic partners with similar academic interests and motivations to help them boost their academic achievement but also classmates with whom they like to spend time and share personal issues.

The influence of friendships on the mental health of maltreated youth: A pre-registered systematic review using a developmental psychopathology perspective.

Friendships are a potential factor that influence maltreated children's risk for psychopathology. This systematic review examined (1) how friendships influence the association between child maltreatment and psychopathology and (2) developmental differences in how friendships influence this association. Four databases were searched. Inclusion criteria were primary study, quantitative, measures of maltreatment and friendship up to the age of 18 years, measures of psychopathology up to the age of 24 years, and a non-maltreated sample. Exclusion criteria were qualitative, reviews or meta-analyses, no distinction between maltreatment and other trauma, and no differentiation between friendships and other support. Risk of bias was assessed. Data were narratively synthesized. Two hundred thirty-five articles were retrieved for full review. Fourteen met inclusion criteria (N = 98,676 participants). Eleven of the fourteen studies found that some aspect of friendships influenced the association between maltreatment and psychopathology, with positive qualities generally decreasing risk and negative qualities increasing risk for psychopathology. However, peer support exacerbated maltreated children's risk for psychopathology in two studies. Only three studies assessed friendship prior to adolescence, which precluded conclusions regarding developmental differences. Future research should consider developmental differences and use findings and validated measures from the peer relations literature to better understand how friendships influence maltreated youth's vulnerability to psychopathology.

Influence of perceived peer behavior on engagement in self-damaging behaviors during the transition to university.

As students transition to university, they experience significant social changes that can affect their behaviors, including self-damaging behaviors like disordered eating, problematic alcohol/drug use, suicidal thoughts, and non-suicidal self-injury (NSSI). Building on prior work, we examined the associations between (1) perceptions of peers' engagement in self-damaging behaviors predicting one's own subsequent engagement in such behaviors (i.e., socialization) and (2) one's own engagement in self-damaging behaviors predicting perceptions of peers' subsequent engagement in such behaviors (i.e., selection). We also examined whether these associations were moderated by the source of influence (close peer/acquaintance) and degree of social disconnection experienced by the student. First-year university students (N = 704) were asked to complete seven monthly surveys. Multilevel models indicated that when students perceived their close peers had engaged in NSSI or suicidal thinking, they had seven times greater odds of future engagement in the same behavior, implying that socialization increases the risk of these behaviors among university students. Perception of acquaintances' NSSI also predicted greater odds of a student's own NSSI the following month. Social disconnection increased the likelihood of matching own behaviors to perceptions of acquaintances' alcohol abuse, highlighting the importance of fostering connections/mentors to reduce self-damaging behaviors on college campuses. Furthermore, when students engaged in alcohol abuse, they had almost four times greater odds of reporting that their acquaintances abused alcohol the following month, emphasizing the importance of the wider social network in alcohol use behaviors.

Association of Childhood Friendship Experience and Depressive Symptoms Among Older Adults: A Causal Mediation Approach.

OBJECTIVES: Few studies to date have investigated the potential mechanisms linking childhood friendship experiences to late-life depressive symptoms. This study examines the association of childhood friendship experiences with depressive symptoms among older adults and the mediating effects of social disconnectedness and cognitive function. METHODS: A retrospective cohort analysis was performed using longitudinal data from a sample of 8,745 participants aged 60 years and above in the China Health and Retirement Longitudinal Study from 2013 to 2018. The causal association of childhood friendship experiences with depressive symptoms and the mediating roles of social disconnectedness and cognitive function were estimated using marginal structural models and the inverse odds ratio weighting method. Mediation proportions and confidence intervals (CIs) were calculated using a bootstrap resampling method. RESULTS: Respondents with greater childhood friendship deficits were more likely to have depressive symptoms (odds ratio: 1.19, 95% CI: 1.11, 1.26) than those with more favorable friendship experiences during childhood. The causal mediation analysis revealed that social disconnectedness, cognitive function, and their combination partially mediated the association of childhood friendship experiences with depressive symptoms by 15.70% (95% CI: 8.66%-24.17%), 17.18 % (95% CI: 7.61%-30.00%), 28.35% (95% CI: 17.75%-42.56%), respectively. DISCUSSION: Friendship experiences during childhood were related to the risk of depressive symptoms in older Chinese adults; more importantly, social disconnectedness and cognitive function partially mediated this association. Thus, improving social engagement and cognitive function in older adults could alleviate the accumulated disadvantages due to childhood friendship deficits and help to improve their psychological well-being.

Seeing myself through the eyes of my peers: Explaining the self-concept of students with and without special educational needs through acceptance and friendship.

INTRODUCTION: Paving the way towards inclusive education, it is essential to aim for positive social outcomes for all students, including cultivating a positive self-concept and fostering acceptance and friendships with peers. Although self-concept, acceptance and friendships are interrelated, research focussing on the relationship between these constructs remains limited. METHOD: This study examined the self-concept, acceptance and friendships of two groups of typically developing students in secondary education (n = 401) and two groups of students in special secondary education with either an intellectual disability (ID) (n = 58) or social, emotional and behavioural difficulties (SEBD) (n = 68). RESULTS: Lower self-concept scores were found for students with ID on some dimensions, whereas typically developing students reported lower acceptance and friendship scores. Multilevel analyses indicated that acceptance is a predictor for several different dimensions of self-concept in the different groups of students, but friendship is less likely to predict self-concept scores. DISCUSSION: The results of the study emphasize the importance of promoting peer acceptance amongst all students in inclusive school settings in order to realize the intended positive social outcomes of inclusive education.

The extended neural architecture of human attachment: An fMRI coordinate-based meta-analysis of affiliative studies.

Functional imaging studies and clinical evidence indicate that cortical areas relevant to social cognition are closely integrated with evolutionarily conserved basal forebrain structures and neighboring regions, enabling human attachment and affiliative emotions. The neural circuitry of human affiliation is continually being unraveled as functional magnetic resonance imaging (fMRI) becomes increasingly prevalent, with studies examining human brain responses to various attachment figures. However, previous fMRI meta-analyses on affiliative stimuli have encountered challenges, such as low statistical power and the absence of robustness measures. To address these issues, we conducted an exhaustive coordinate-based meta-analysis of 79 fMRI studies, focusing on personalized affiliative stimuli, including one's infants, family, romantic partners, and friends. We employed complementary coordinate-based analyses (Activation Likelihood Estimation and Signed Differential Mapping) and conducted a robustness analysis of the results. Findings revealed cluster convergence in cortical and subcortical structures related to reward and motivation, salience detection, social bonding, and cognition. Our study thoroughly explores the neural correlates underpinning affiliative responses, effectively overcoming the limitations noted in previous meta-analyses. It provides an extensive view of the neural substrates associated with affiliative stimuli, illuminating the intricate interaction between cortical and subcortical regions. Our findings significantly contribute to understanding the neurobiology of human affiliation, expanding the known human attachment circuitry beyond the traditional basal forebrain regions observed in other mammals to include uniquely human isocortical structures.

Biopsychosocial contexts influence adult cognitive function concurrently and longitudinally.

Background: Cognitive aging is a complex process that impacts human behavior. Identifying the factors that preserve cognitive functioning is a public health priority, given that 20% of the US population will be at least 65 years old in the next decade. Biopsychosocial determinants of cognitive decline across the lifespan are often examined as ecological factors that independently moderate cognitive aging, despite the known complexity surrounding these relationships. Objective: We aimed to address this gap by exploring the synergistic and simultaneous relationship between risk and protective factors on cognitive functioning. Method: Using the MIDUS study datasets, we examined the relationships among physiological markers, friendship quality, and global cognition functioning, concurrently and longitudinally over ten years. Our participants included 929 healthy (417 men, 512 women) adults (average age at Time 1: 54.6 ± 11.6 years). Exploratory analyses examining the effects of racial minority status were also conducted. Results: Cross-sectionally, age, and friendship quality moderated the relationship between vagally-mediated heart rate variability (vm-HRV) and cognition such that younger adults with greater friendship quality had a negative relationship between vm-HRV and cognitive performance; our unexpected finding suggests the heart-brain relationship is sensitive to the biopsychosocial environment. Longitudinally, higher IL-6 levels at Time 1 predicted poorer cognitive performance a decade later, but only among those with greater levels of friendship quality, especially for white-identifying individuals. Conclusions: The relationships among physiological risk factors, social protective factors and cognitive functioning appear to be temporally different during mid-adulthood. Given many of the whole sample findings were not replicated within the racial minority subgroup, we suggest that these relationships should be examined in a larger and more diverse racial minority sample to determine whether this study lacked the power necessary to detect a relationship or if the relationships are in fact different by racial minority sub-group. In addition, future research should overcome the study's reliance on healthy adults and self-report measures of friendship quality by including adults with pre-existing cognitive impairments, and employing more real-time measures of friendship quality, such as daily diary or ecological momentary assessment.

Importance of Friendship and Minimal Group Membership in 4-6-Year-olds' and 9-12-Year-olds' Sharing Behavior in China.

Strategies for favoring close others, such as friends and in-group members, benefit individuals and society. Although younger and older children apply these sharing strategies, how they integrate these relationships remain understudied. Friendship and group membership sometimes conflict (e.g. a friend from another, even a rival group), driving the question of how children behave in such situations. To address this question, this preregistered study recruited 121 4-6-year-olds and 94 9-12-year-olds from a middle-class community in China. A 2 (friend vs. stranger) by 2 (in vs. out-group) between-subjects design was applied per age group. Participants were asked to share seven objects with a recipient, who was either a stranger, or a previously nominated friend and from an in- or out-group (manipulated in the Minimal Group Paradigm). The results showed that children in both age groups shared more with friends than with strangers. However, only 4-6-year-olds shared more resources with in-group members than with out-group ones. Moreover, 4-6-year-olds did not distinguish between an out-group friend and an in-group stranger, while 9-12-year-olds shared more with an out-group friend relative to an ingroup stranger, indicating that friendship outweighs minimal group membership only among 9-12-year-olds. Furthermore, there was an interaction between age and minimal group membership, implying a decrease in the minimal group effect between 4-6-year-olds and 9-12-year-olds. Accordingly, the implications of friendship and minimal group effects, and their relative influence on sharing during childhood are discussed.

Bystander Intervention in Coercive Control: Do Relationship to the Victim, Bystander Gender, and Concerns Influence Willingness to Intervene?

With rates of coercive control (CC) increasing, there is a need to ensure that intervention programs are underpinned by evidence-based research. Current interventions are scarce, with their efficacy rarely established. Most current interventions appear to rely on victims seeking support from formal sources/agencies, despite suggestions that victims are more likely to confide in people they know, such as their friends. Researchers suggest that a victim's friends may provide an effective source of support and intervention. The aim of this study was to fill the gap in the literature exploring whether the closeness of the relationship to the victim, bystander gender, and bystander concerns influenced attitudes toward intervening in CC situations. The study used an experimental design, whereby participants were randomly allocated to read a vignette depicting a CC scenario involving a friend, colleague, or stranger, and quantitative methods were used to examine bystanders' willingness and concerns about intervening. The sample was 340 Australian participants (229 female, 111 male), recruited from social media, namely community Facebook groups. The results indicated that friends were significantly more willing to intervene than colleagues or strangers, while strangers reported the highest concerns about intervening. Females reported significantly higher willingness to intervene than men despite also reporting higher concerns. Exploratory analysis of concerns about intervening revealed that the participants were most concerned about risk of harm and their beliefs in their ability to successfully intervene. These findings have implications for bystander intervention programs and campaigns, including offering a range of potential directions to enhance intervention program content.

Roles of expressed gratitude and apologies in predicting reciprocal responsiveness.

Research has indicated the critical role of responsiveness in facilitating close relationships, but what communication leads to enhanced responsiveness has not been fully explored. We hypothesized that gratitude and apologies facilitate responsiveness within friendship relationships in Japan. In Experiment 1 (n = 669), receiving gratitude, apologies, or both gratitude and apologies increased recipients' perceptions of the expresser's responsiveness more than receiving a message without either gratitude or apologies. In Experiment 2 (n = 139), the participants who received gratitude as well as receiving both gratitude and apologies (but not just apologies) wrote more responsive messages back to the expresser than those who received a message without either gratitude or apologies. Gratitude and apologies played unique roles in promoting responsiveness within friendship relationships.

Communication modality matters: Co-rumination via in-person versus digital modalities has different prospective associations with depression and friendship quality.

INTRODUCTION: Co-rumination is an interpersonal emotion regulation strategy in which negative feelings and problems are discussed perseveratively with another person. Although co-rumination is salient in adolescence, research to date has focused on co-rumination occurring in person and has not kept pace with the surge in digital communication that begins in adolescence. This study examined the degree, associations among, and consequences (i.e., depressive symptoms, and friendship quality) of adolescents' co-rumination via in-person, text, social media, and phone modalities. METHODS: Adolescents (n = 109; 51 girls, 57 boys, 1 nonbinary; Mage = 12.83 years) residing in Canada, completed self-report questionnaires on co-rumination, depressive symptoms, and friendship quality for up to 2 years. RESULTS: Adolescents engaged in co-rumination across all modalities, particularly in-person. Findings indicated a negative association between in-person co-rumination at baseline and in-person co-rumination over time. Whereas less text co-rumination was associated with increased depressive symptoms over time, greater phone co-rumination was associated with increased depressive symptoms over time. Although greater in-person co-rumination was positively associated with friendship quality concurrently, it was negatively associated with friendship quality prospectively. CONCLUSIONS: Taken together, co-rumination outcomes may vary depending on communication modality. Implications for adolescents' mental and social wellbeing are discussed.

Facilitating virtual social connections for youth with disabilities: lessons for post-COVID-19 programming.

PURPOSE: Social connections are essential for the development of life skills for youth. Youth with disabilities have long faced barriers to meaningful social connections. The onset of COVID-19 increased barriers to social connections for all youth, and also led to enhanced use of virtual platforms in paediatric rehabilitation programming. Harnessing this opportunity, service providers created a suite of online programs to foster social connections and friendships. The current study explores participant and service provider experiences of such programs. METHODS: This qualitative descriptive study used interviews and focus groups to explore how youth with disabilities (n = 8), their parents (n = 7), and service providers (n = 13) involved in program development and delivery experienced the programs, the accessibility of the virtual platforms, and their social connections in relation to program participation. RESULTS: Participants were satisfied with the programs' content, accessibility and ability to meet their social needs. Qualitative themes included facilitating social connections, accessibility of virtual spaces, and recommendations for future virtual programming. DISCUSSION: For youth with disabilities who have been historically marginalized in social spheres, the newly ubiquitous infrastructure regarding virtual programming must be supported and enhanced. A hybrid approach involving virtual/in-person options in future programming is recommended.

Youth with disabilities can benefit from social connections on virtual platforms in terms of physical access to social spaces and opportunities to communicate in alternative waysFor some youth with disabilities, virtual social connections can be the only feasible and readily available option for reducing social isolation due to physical barriers to accessWhen offering virtual program options, service providers should consider the various benefits of connecting with the physical, communication-based, interaction-based, access-based and other barriers to virtual connection.

The coevolution of bullying and friendship networks.

The coevolution of bullying and friendship networks and the moderating effects of classroom bullying popularity norms were examined in a sample of 965 students (52.1% boys) in 22 fourth- and fifth-grade classes. Longitudinal social network analysis showed that children were more likely to bully their friends' victims (bully influence effect) and to be bullied by their friends' bullies (victim influence effect); two children bullying the same child were likely to be friends (bully selection effect), and two victims bullied by the same child were likely to be friends (victim selection effect). Bullying popularity norms served as moderators, and the bully selection effect was significant weaker in the context of low bullying popularity norms. This study adds understanding of bullying as a group process and provides implications for preventing school bullying.
