... This could be due to a variety of factors, including emotional stress, changes in social support networks, or differences in health behavior following a separation or divorce. For divorced or separated individuals, the lack of a partner may result in less encouragement or support for vaccination, leading to higher rates of hesitancy [32,33]. In contrast, other studies showed no association between marital status and COVID-19 vaccine hesitancy [80]. ...

... It is important to recognize that social networks are shaped by structural characteristics, such as reciprocity (the tendency for friendship nominations to be mutual) and transitivity (the tendency for individuals to nominate friends of their friends). To gain a deeper insight into friendship dynamics, it is imperative to account for these structural factors (Copeland et al., 2023), as they are not only endogenous to the network structure but also important concepts in peer relationships. For example, reciprocity is a structural attribute frequently observed in peer interactions (Laursen & Hartup, 2002), and has a notable impact on adolescents' lives (Bagwell et al., 2021;Vaquera & Kao, 2008). ...

... Through the process of acculturation, efforts to gain more peer acceptance can lead to conflict in family relations [39]. A study among first-generation Hispanic children had lower rates of obesity compared to later generations; having a social network with more second-generation friends was associated with a higher BMI among first-generation Hispanic children [40]. While rates of alcohol use were lower among first-generation Latinx youth at baseline compared to their peers, rates of alcohol use were among the highest when reassessed two years post-resettlement [41]. ...

... The pain caused by hurting can help adolescents escape from numbness and illusion. It can also gain the understanding of others and allow them to make changes [59]. A study found that feelings of despair and hopelessness in adolescents lead to more loneliness and depression [60,61], which may trigger the occurrence of self-injury behavior [62]. ...

... Before this pandemic, engaging in social activities, performing cognitive and physical activities, and having a productive daily routine had been the mainstay therapy, especially for adults with dementia [1,2]. However, strict social isolation was recommended during COVID-19, especially for older people with the highest risk for severe COVID-19 disease and death [3,4], eliminating many community activities and restricting visitors to the home. Previous quarantines in human history had a negative psychological impact on outcomes such as anger, depression, and loneliness in the general population [5][6][7]. ...

... Gerade mit Blick auf die Lebenslaufwirkung von Sozialpolitik kann eine Veränderung von Netzwerkgröße und -zusammensetzung als Ursache und Folge von Maßnahmen im Zeit-verlauf betrachtet werden, weil persönliche Netzwerke sowohl Information als auch Unterstützung bereitstellen. Copeland und Liu (2023) analysierten beispielsweise Paneldaten vom National Social Life, Health, and Aging Project, um vorherzusagen, wie präpandemische persönliche Netzwerke Unterstützung während der Covid-19-Pandemie für ältere Erwachsene beeinflussen. Die Ergebnisse sind instruktiv für Maßnahmen, die soziale Unterstützung stärken, oder für die Identifikation vulnerabler Gruppen, die besonders unter fehlender Unterstützung leiden. ...

... The findings also suggested that women were more likely than men to have experienced normalscale depression. Although depression can afflict people of any gender, there are significant patterns and distinctions in the occurrence, manifestation, and management of depression that are specific to gender (Copeland, 2023). Table 3 presented that for those respondents who were single, the results showed a high leaning toward depression. ...

... The literature about parental loss and grief primarily focuses on childhood and adolescent parental bereavement with comparatively little on young adult parental bereavement (Brewer & Sparkes, 2011;Kamis et al., 2022;Porter & Claridge, 2021). ...

... Friendship and popularity are two independents, but associated social dimensions which define adolescents' social peer contexts (e.g., Kamis and Copeland, 2020). At the empirical level, a recent cross-sectional study which investigated the association between perceptions of friendship and popularity at the dyadic level found a significant moderate co-occurrence between friendship and popularity perception ties (Vörös et al., 2019). ...

... Suicide prevention in the school environment must be multidisciplinary: peers, teachers, doctors, nurses, social workers, psychologists, and parent organizations (Copeland et al., 2020;Johnson and Parsons, 2012;Singer et al., 2019). Changes in academic performance are essential indicators of psychological distress in students, not only due to issues related to the school environment but also in the familial context (Kim, 2021;Lear et al., 2020). ...
