Abstract The study examined whether reciprocal friendship quantity or quality can mitigate genetic vulnerability for depression symptoms in children. The sample comprised 168 monozygotic twin pairs and 126 same-sex dizygotic twin pairs assessed in Grade 4 (mean age = 10.04 years). Friendship participation was measured via reciprocal nominations of close friendships within the classroom. Friendship quality was measured through self-reports. Depression symptoms were measured through teacher and… 

Friendship Experiences and Anxiety Among Children: A Genetically Informed Study

TLDR
Results indicated that children with a strong genetic disposition for anxiety were more likely to have anxious friends than nonanxious friends, and a possible contagion of anxiety symptoms between reciprocal best friends when perceived negative features of friendship were high.

Links Between the Mother–Adolescent and Father–Adolescent Relationships and Adolescent Depression: A Genetically Informed Study

TLDR
It is suggested that relationship quality with both parents might impact girls’ and boys’ depressive symptoms but that these associations depend to some extent on adolescents’ genetic vulnerabilities.

The Relations Between Anxiety Symptoms and Friendships in Adolescence

Anxiety symptoms can often be experienced as a silent struggle in adolescence, as many anxious adolescents do not exhibit outward symptoms. Identifying adolescents who are struggling with

Predictive links between genetic vulnerability to depression and trajectories of warmth and conflict in the mother-adolescent and father-adolescent relationships.

TLDR
Results suggest that adolescents' depression symptoms may affect girls' and boys' relationship with their parents in a similar way, with specific sex-patterns revolving more around the sex of the parent.

Relations of friendship experiences with depressive symptoms and loneliness in childhood and adolescence: A meta-analytic review.

TLDR
The results suggest that friendship experiences may be more closely linked with loneliness than depressive symptoms and that negative friendship quality may be related to friendship experiences more strongly than number of friends or positive friendship quality.

Longitudinal Linkages Between Coparenting and Subsequent Friendship Quality in Middle Childhood

Children who have a good relationship with a best friend experience better social and emotional adjustment, making it critical to identify factors that foster the development of high-quality

Associations Between Sibling Relationship Quality and Friendship Quality in Early Adolescence: Looking at the Case of Twins

TLDR
Findings speak to the important role of the sibling relationship in the development of good quality friendship relations in twins and show stronger stability of the twin relationship quality compared to friendship quality.

Treatment of friendship problems in children with attention-deficit/hyperactivity disorder: Initial results from a randomized clinical trial.

TLDR
Although PFC showed some efficacy for affecting children's friendship behaviors, these changes may not translate into friendship quality, and moderation analyses suggested that PFC may contribute to better friendship quality among families who had previous psychosocial treatment, as well as children with comorbid externalizing disorders.

The role of family and peer factors in the development of early adolescent depressive symptoms: A latent class growth analysis

Few studies have explored the trajectories of Chinese early adolescent depressive symptoms or comprehensively considered the factors of family and peers. The present study aimed to identify the

Genetic moderation of environmental risk for depression and anxiety in adolescent girls

TLDR
There is an environmentally mediated effect of life events on depression/anxiety, and genetic factors play a significant role in individual differences in susceptibility to these environmentally mediated risks.

TLDR
It is found that multiple aspects of adolescents' social relations uniquely contribute to feelings of internal distress, including peer crowd affiliation, peer victimization, and qualities of best friendships and romantic relationships.

Gene–environment interaction between peer victimization and child aggression

TLDR
Genetic modeling showed thatpeer victimization is an environmentally driven variable that is unrelated to children's genetic disposition, albeit only in girls, and provided support for the notion of a gene–environment interaction between peer victimization and child's genetic risk for aggressive behavior.

Gender Differences in the Interpersonal Consequences of Early-Onset Depressive Symptoms

Although research has identified gender differences in the interpersonal antecedents of depressive symptoms in youth, little is known about gender differences in the interpersonal consequences of

5-HTTLPR moderates the effect of relational peer victimization on depressive symptoms in adolescent girls.

TLDR
The findings support the diathesis-stress model of depression: having two 5-HTTLPR short alleles confers vulnerability to depressive symptoms in adolescent girls when they experience relational peer victimization.

TLDR
Results indicated that among girls higher levels of social anxiety were associated with adolescents' greater susceptibility to peer contagion, and among boys, higher Levels of friends' peer perceived popularity and lower levels of positive friendship quality each wereassociated with greater susceptibility with depressive symptom contagion.

Associations between Peer Relationships and Depressive Symptoms

Popularity and friendship are distinct constructs within the domain of peer relationships, and each is related to children's adjustment. The current study extended earlier research by testing whether

TLDR
The paper argues for the need to study the process and mechanisms in friendship formation among twin children because the findings might inform not only studies of friendship but also behavioural genetic research.

The heritability of depressive symptoms: multiple informants and multiple measures.

TLDR
Results underscore the utility of using multiple informants to measure children's behavior and provide a foundation for follow-up of these twins in later adolescence.
