The power of friendships in adolescents' daily lives
Friends play a critical role in adolescent development, yet relatively little is known about how friendship interactions in adolescents' daily lives relate to their affective experiences. This study examined bidirectional associations between friendship interaction quality (i.e., warmth and conflict) and momentary affect, as well as whether these associations were moderated by individual differences (i.e., depressive symptoms, habitual rumination…
From Basic Psychological Need Frustration to Stress Responses
Examining systemic inflammation as a pathway linking peer victimization to depressive symptoms in adolescence
BACKGROUND: Adolescents exposed to victimization are at an increased risk for a variety of adverse mental health outcomes, including depressive symptoms. Yet, the biological pathways underlying these associations remain poorly understood. Focusing on within-person processes, we examined whether low-grade systemic inflammation mediated the longitudinal associations between peer victimization and depressive symptoms in adolescence. METHODS: = 12.69…
Within-person associations between emotion regulation and negative affect in adolescents’ daily life
Adolescence is marked by elevated levels of negative affect (NA) and is a crucial period for the development of emotion regulation (ER). To date, relatively little is known about how adolescents' daily use of different ER strategies (ERS) is associated with momentary affective experiences. To elucidate these dynamics, we investigated whether (a) within-person differences in using different ERS were related to momentary NA and positive affect, (b)…
Why adolescents conform to high-status peers
This study examined whether conformity to high- but not low-status e-confederates was associated with increases in identification with popular peers and subsequent increases in self-esteem. A sample of 250 adolescents (55.1% male; Mage = 12.70 years; 40.3% White, 28.2% Black, 23.4% Hispanic/Latino, and 7.7% multiracial/other) participated in a well-established experimental chat room paradigm where they were exposed to norms communicated by high- …
Implementation of a minimally invasive cell culture system to measure the regulation of inflammation in a school‐based sample of adolescents
Dysregulated inflammation underlies many human diseases, and measures of responsiveness to activation, and sensitivity to inhibition, provide important information beyond baseline assessments of chronic inflammation. This study implements a simplified cell culture protocol in a school‐based setting, using finger stick capillary blood collected from 333 adolescents (age 11.4–15.6 years) incubated with lipopolysaccharide (LPS). Median cytokine resp…
Should Adolescents Listen to Their Hearts? A Closer Look at the Associations Between Interoception, Emotional Awareness and Emotion Regulation in Adolescents
The aim of the current study was to replicate findings from prior work among adults showing that individuals with better interoceptive skills have more emotional awareness, and show better emotion regulation abilities, in a sample of adolescents and by relying on instructions that reduce the contamination of known confound variables. A total of 102 Belgian adolescents ( M age = 14.10 years, SD age = .63; 50 males) completed self-report questionna…
Risk and Protective Effects of Need for Approval on Self-Injury in Adolescent Girls
Feeling better now? Being defended diminishes daily mood problems and self‐blame in victims of bullying
BACKGROUND: School bullying is a group phenomenon in which being defended by peer bystanders may buffer against the development of psychological problems in victims. AIMS: This registered report examines whether being defended diminished victims' daily mood problems and self-blame, both from a within- and between-person perspective. MATERIALS AND METHODS: Daily diary data were collected from n = 1669 Finnish 7th-9th grade students (M age = 14.45;…
The relationship between perceived stress and depressive symptoms in adolescents during high stress
INTRODUCTION: This study examined the moderating role of adaptive and maladaptive emotion regulation in the relationship between general perceived stress and depressive symptoms during the first coronavirus disease 2019 (COVID-19) lockdown in March-April 2020 in Belgium, while controlling for past depressive symptoms in 2016. METHODS: Participants were 110 adolescents (55% female; Mage = 16, SDage = 1.80) who filled out different questionnaires a…
Disentangling the effects of peer status and peer victimization on perceived physical health in adolescence
INTRODUCTION: Although exposure to peer victimization during adolescence has been linked to poorer (perceived) physical health, little is known about how multiple peer stressors may independently and conjointly be related with adolescent physical health outcomes. The current study investigated the unique, interactive, and cumulative effects of peer victimization and two types of peer status (i.e., peer preference and peer popularity) on adolescen…
Reciprocal associations between peer problems and non‐suicidal self‐injury throughout adolescence
BACKGROUND: Peer problems have emerged as important predictors of Non-Suicidal Self-Injury (NSSI) development during adolescence. However, the possibility that adolescents who engage in NSSI may, in turn, be at increased risk for experiencing difficulties with their peers has rarely been examined. This study investigated the reciprocal associations between peer problems (e.g. peer victimization, friendship stress and loneliness) and NSSI througho…
Non-Suicidal Self-Injury in Adolescence
For many adolescents, the COVID-19 pandemic represents a uniquely challenging period, and concerns have been raised about whether COVID-19-related stress may increase the risk for self-injurious behaviors among adolescents. This study examined the impact of pre-existing vulnerabilities on the occurrence and frequency of Non-Suicidal Self-Injury (NSSI) through COVID-19-related stress, and whether the impact of COVID-19-related stress on NSSI was b…
A meta-analysis of longitudinal peer influence effects in childhood and adolescence
For decades, psychological research has examined the extent to which children’s and adolescents’ behavior is influenced by the behavior of their peers (i.e., peer influence effects). This review provides a comprehensive synthesis and meta-analysis of this vast field of psychological science, with a goal to quantify the magnitude of peer influence effects across a broad array of behaviors (externalizing, internalizing, academic). To provide a rigo…
Bully Victimization
Adolescents tend to form friendships with similar peers and, in turn, their friends further influence adolescents' behaviors and attitudes. Emerging work has shown that these selection and influence processes also might extend to bully victimization. However, no prior work has examined selection and influence effects involved in bully victimization within cliques, despite theoretical account emphasizing the importance of cliques in this regard. T…
Peer Influence, Peer Status, and Prosocial Behavior
Experimentally measured susceptibility to peer influence and adolescent sexual behavior trajectories
A performance-based measure of peer influence susceptibility was examined as a moderator of the longitudinal association between peer norms and trajectories of adolescents' number of sexual intercourse partners. Seventy-one 9th grade adolescents (52% female) participated in an experimental "chat room" paradigm involving "e-confederates" who endorsed sexual risk behaviors. Changes in participants' responses to risk scenarios before versus during t…
Adolescents misperceive and are influenced by high-status peers’ health risk, deviant, and adaptive behavior
Most peer influence research examines socialization between adolescents and their best friends. Yet, adolescents also are influenced by popular peers, perhaps due to misperceptions of social norms. This research examined the extent to which out-group and in-group adolescents misperceive the frequencies of peers' deviant, health risk, and adaptive behaviors in different reputation-based peer crowds (Study 1) and the prospective associations betwee…
Direct and Indirect Peer Socialization of Adolescent Nonsuicidal Self‐Injury
This study examined direct and indirect forms of peer socialization of non-suicidal self-injury (NSSI) in adolescent friendship networks. Data were collected among 348 adolescents (55% females; M age = 15.02 years; SD = 0.53) at 4 assessment waves. Stochastic actor-based models revealed no evidence for direct socialization of NSSI: adolescents whose friends reported higher NSSI did not increase their NSSI over time. However, indirect forms of soc…
Selection, Deselection, and Socialization Processes of Happiness in Adolescent Friendship Networks
This study investigated selection, deselection, and influence processes of happiness in adolescent friendship networks. Longitudinal data on friendship networks and happiness of 426 adolescents ( M = 15.78, SD = 0.65) were analyzed, using stochastic actor‐based models. Although happiness similarity did not predict friendship formation (selection), happiness dissimilarity predicted friendship dissolution (deselection). In addition, adolescents inf…

Regulatory Self‐efficacy as a Moderator of Peer Socialization Relating to Italian Adolescents' Alcohol Intoxication
The present study investigated regulatory self‐efficacy (RSE) as a predictor of friendship and adolescent alcohol intoxication and as a moderator of peer socialization processes related to alcohol intoxication. The longitudinal sample included 457 Italian adolescents (262 females and 195 males) ranging in age of 14 to 20 years (M = 16.1 years of age). Sociometric and behavioral data were collected at the beginning and end of the academic school y…
Similarity in depressive symptoms in adolescents' friendship dyads
This study examined friendship selection and socialization as mechanisms explaining similarity in depressive symptoms in adolescent same-gender best friend dyads. The sample consisted of 1,752 adolescents (51% male) ages 12-16 years (M = 13.77, SD = 0.73) forming 487 friend dyads and 389 nonfriend dyads (the nonfriend dyads served as a comparison group). To test our hypothesis, we applied a multigroup actor-partner interdependence model to 3 frie…
Older people's sense of coherence
Few studies have explored the combination of individual and contextual conditions that influence psychological health among older people. This study aimed to analyse the sense of coherence (SOC) in a sample of Italian senior citizens in relation to gender, educational level, living arrangements and former employment, when controlling for age. The short version of the SOC scale (Antonovsky 1987), which has items for the ‘comprehensibility’, ‘manag…
