Parent-Adolescent Discrepancies Regarding Adolescents' Peer-Related Loneliness: Associations with Adolescent Adjustment

Lonely and Self-Centered? A Meta-Analysis of the Link Between Prosociality and Loneliness

While loneliness may motivate individuals to approach others, it may simultaneously increase their focus on self-preservation, resulting in egocentric behavior. Since the evidence linking loneliness and prosociality is inconclusive, the current meta-analysis aims to explore this relationship. Through a systematic search of databases, we identified 35 studies involving 44,764 participants. A small effect size for a negative correlation between loneliness and prosociality (r = -0.12, 95% CI: [-0.19, -0.05]) was found using the random effects model. The effect was not moderated by participants' sociodemographic characteristics or the WEIRDness of the sample but differed between types of measurement and forms of prosocial behavior. Our findings highlight the importance of understanding the processes perpetuating the link between loneliness and decreased prosociality, as this tendency may pose difficulties in restoring social connections, cooperating with others, or aiming for common goals.

Cultural Dimensions Moderate the Association between Loneliness and Mental Health during Adolescence and Younger Adulthood: A Systematic Review and Meta-Analysis

Cultural factors, such as country or continent, influence the relationship between loneliness and mental health. However, less is known about how cultural dimensions moderate this relationship during adolescence and younger adulthood, even if these dimensions manifest as country or continent differences. This study aims to examine the potential influence of Hofstede's cultural dimensions on this relationship using a three-level meta-analysis approach. A total of 292 studies with 291,946 participants aged 10 to 24 were included in this study. The results indicate that cultural dimensions, such as individualism vs. collectivism, indulgence vs. restraint, power distance, and long-term vs. short-term orientation, moderated the associations between loneliness and social anxiety, stress, Internet overuse, and negative affect. The association between loneliness and mental health was not moderated by cultural dimensions, such as masculinity and uncertainty avoidance. These findings suggest that culture's influence on the association between loneliness and mental health is based on a domain-specific mechanism.

Development and initial validation of a parent report measure of youth belongingness and burdensomeness

OBJECTIVE

The Interpersonal Theory of Suicide (ITS) implicates thwarted belongingness and perceived burdensomeness as casually related to suicide desire. The self-report Interpersonal Needs Questionnaire (INQ) is the most commonly used measure to assess belongingness and burdensomeness, including in youth. No parent-report version of the INQ exists. The current study adapted the ten-item version of the INQ (INQ-10) for parent report of youth belongingness and burdensomeness, thereby moving ITS research in youth to a multi-informant measurement approach, and examined its factor structure and convergent and concurrent validity.

METHODS

Participants were 168 clinic-referred youths ages 9-17 years (58.9% female; M_age  = 11.91) and their parents.

RESULTS

Findings supported a two-factor structure of the parent INQ. In support of convergent and concurrent validity, parent-reported belongingness and burdensomeness were significantly associated with youth-reported belongingness and burdensomeness, suicide ideation, anxiety symptoms, depressive symptoms, and impairment.

CONCLUSIONS

The current study provides initial support the INQ-parent version as a valid measure to complement youth self-reports of belongingness and burdensomeness.

Spotting Loneliness at School: Associations between Self-Reports and Teacher and Peer Nominations

In two independent studies, we aimed to examine the extent to which teacher and peer nominations of loneliness are associated with children’s and adolescents’ self-reported loneliness, respectively. Additionally, we examined whether loneliness nominations from teachers and peers were informative above and beyond peer status and social behaviors associated with loneliness. In Study 1 (N = 1594, M_age = 9.43 years), teacher nominations of loneliness showed a small to moderate correlation with children’s self-reported loneliness as assessed using the Loneliness and Social Dissatisfaction Questionnaire (LSDQ). The results of a hierarchical regression analysis showed that teacher nominations of loneliness predicted children’s self-reported loneliness above and beyond teacher nominations of peer status and social behaviors. In Study 2 (N = 350, M_age = 13.81 years), peer nominations of loneliness showed a small to moderate correlation with adolescents’ self-reported loneliness as assessed using the peer-related loneliness subscale of the Loneliness and Aloneness Scale for Children and Adolescents (LACA). The results of a hierarchical regression analysis showed that peer nominations of loneliness predicted adolescents’ self-reported loneliness above and beyond peer nominations of peer status and social behaviors. We conclude that loneliness nominations are valuable, but caution is needed when they are used exclusively to identify lonely children and adolescents.

School and Cybervictimization Across High School: Normative Developmental Trajectories and Bidirectional Links with Loneliness

The current study examines normative developmental trajectories of school and cybervictimization across 3 years of high school and tests whether school and cybervictimization experiences predict increases in loneliness at school or whether loneliness at school increases the risk of victimization. Gender differences are also explored. Data were drawn from a longitudinal sample of 4,339 ethnically diverse U.S. adolescents (M_age  = 15.02) who completed surveys in 9th, 10th, and 11th grades. Whereas school victimization decreased, cybervictimization increased across high school. School-based victimization and loneliness were bidirectionally related across time (controlling for cybervictimization), but cybervictimization and loneliness were not related (controlling for school victimization). The findings provide a nuanced account of the associations between school and cybervictimization with feelings of isolation at school.

A SNP, Gene, and Polygenic Risk Score Approach of Oxytocin-Vasopressin Genes in Adolescents' Loneliness

Not much is known regarding underlying biological pathways to adolescents' loneliness. Insight in underlying molecular mechanisms could inform intervention efforts aimed at reducing loneliness. Using latent growth curve modeling, baseline levels and development of loneliness were studied in two longitudinal adolescent samples. Genes (OXTR, OXT, AVPR1A, AVPR1B) were examined using SNP-based, gene-based, and polygenic risk score (PRS) approaches. In both samples, SNP- and gene-based tests showed involvement of the OXTR gene in development of loneliness, though, significance levels did not survive correction for multiple testing. The PRS approach provided no evidence for relations with loneliness. We recommend alternative phenotyping methods, including environmental factors, to consider epigenetic studies, and to examine possible endophenotypes in relation to adolescents' loneliness.
