Abstract Given the rising prevalence in Asian adolescents who engage in multiple risk behaviors and the lack of a consolidated evaluation of multibehavior intervention outcomes, this systematic review examined the effectiveness of lifestyle interventions targeting two or more of the “Big 6” behavioral risk factors: physical inactivity, excessive sedentary time, poor sleep, unhealthy diet, smoking, and alcohol use. A comprehensive search of seven databases (Public Medline, Embase, Psychological Information Database, Scopus, Web of Science, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Controlled Trials) identified 28 eligible randomized controlled trials. Of these, 13 demonstrated effectiveness in addressing two or more of the target behaviors, most commonly addressing combinations of physical activity and diet (n = 5), and physical activity and sedentary behavior (n = 3). Effective interventions were delivered over 3 to 39 weeks, with weekly durations ranging from 0.5 to 5 h, and all were school-based. Seven interventions incorporated active family involvement, and two included digital components either independently or alongside family engagement. Nine interventions were guided by explicit theoretical frameworks and consistently applied behavior change techniques that provided clear and actionable guidance. The evidence suggests that multibehavior interventions show potential for improving adolescent health behaviors in Asia, particularly when delivered in school settings, supported by families, enhanced through accessible digital technologies, and grounded in theory-based strategies.

Abstract Social anxiety symptoms peak in adolescence, a period of heightened vulnerability due to normative cognitive, affective, and social changes. Although both parents have robust influences on social anxiety symptoms, popular theory suggests fathers play a particularly salient role in the manifestation of these symptoms. Yet, studies examining unique parental contributions yield mixed findings in this area. Moreover, existing parenting meta-analyses have exclusively considered mothers’ and fathers’ parenting behaviors on social anxiety independently, thereby mischaracterizing their unique contributions by overlooking their shared “interparental” covariance. This review fills this gap by employing a meta-analytic structural equation modeling (MASEM) approach to jointly estimate the unique and shared effects of maternal and paternal warm and controlling behaviors on youth social anxiety symptoms. Independent models replicated prior findings, linking maternal/paternal warmth and control to social anxiety symptoms with small-to-medium effect sizes. However, the joint MASEM models offer insights beyond previous findings. Particularly, mothers’ and fathers’ warmth had reduced, but unique, comparably sized small associations with adolescent social anxiety symptoms. Further, only maternal control was uniquely linked to increased symptomology and paternal control was nonsignificant. Findings underscore the distinct roles of mothers and fathers in adolescent social anxiety and demonstrate the utility of the MASEM approach in disentangling unique parenting effects on children's development.

Abstract Bullying victimization and cyberbullying victimization are pervasive phenomena with documented adverse psychological consequences. Although loneliness has been conceptualized as both an antecedent and outcome of victimization experiences, the nature of these relationships remains insufficiently understood. This systematic review synthesizes evidence on the relationships between bullying victimization, cyberbullying victimization, and loneliness, while examining conceptualizations and assessment of loneliness. Following PRISMA guidelines, 7253 articles were evaluated, including 100 studies meeting inclusion criteria. Selected studies included samples from a variety of countries, balanced in terms of gender and with ages ranging from childhood to adulthood. Most studies emphasized loneliness as distress arising from perceived deficiencies in social relationships, with measurement approaches varying considerably. The findings reveal complex, bidirectional relationships between victimization and loneliness, with stronger associations in adolescent samples compared to younger children or adults. While traditional bullying consistently demonstrated significant associations with loneliness, the cyberbullying-loneliness relationship showed greater variability. Some factors such as bystander behaviour or school connectedness moderated this relationship, being this protective effect stronger for girls. This review identifies critical gaps in understanding how different forms of loneliness interact with victimization across developmental stages and cultural contexts, providing a foundation for designing targeted interventions that address loneliness in victimized youth, particularly during adolescence.

Abstract Although the beneficial psychological effects of self-compassion are well documented, less is known about its contributing factors. Attachment theory and social mentality theory posit that parenting might contribute to adolescent self-compassion. Nevertheless, no previous meta-analysis has systematically investigated this association. Furthermore, self-compassion might be a mediator in explaining the well-established link between parenting and adolescent internalizing problems, although previous meta-analyses have rarely systematically explored this nor investigated how these processes unfold differently for adolescents with different characteristics and from different cultures. This meta-analysis included 110 articles comprising 120 independent samples with 88,349 adolescents. The results of three-level meta-analyses revealed that positive and negative parenting were associated with higher and lower adolescent self-compassion, respectively, with small to moderate effect sizes. Additionally, meta-analytic structural equation modeling result showed that self-compassion mediated the relationships between both positive and negative parenting and internalizing problems. These associations in the mediation model were largely equivalent across adolescent age, gender and different cultures except for a stronger effect of self-compassion on internalizing problems in samples with higher proportions of female adolescents and from more individualistic cultures. The findings imply that parenting and adolescent self-compassion might be crucial targets for mitigating adolescent internalizing problems.

A growing body of research indicates that problematic social media use can have detrimental effects on adolescents' mental health and well-being. This systematic review aims to synthesize evidence on longitudinal risk factors contributing to the development of problematic social media use in adolescents, defined as the use of social media impacting physical or mental well-being. The review was conducted following PRISMA guidelines. A comprehensive literature search was performed on PubMed, PsycINFO, and Embase databases, including articles published from 2010 onwards. Out of 1,729 screened articles, 23 were included. Findings on risk factors related to individuals and their social environment were categorized into nine groups: motivations for use, parenting factors, adverse childhood experiences, peer factors, emotions, self-regulation, personality, mental health, and the impact of the COVID-19 pandemic. Peer factors (e.g., poor social relationships, social comparison, fear of missing out, negative peer pressure, exposure to relational aggression), negative emotions, personality traits (e.g., sensation seeking), and poor mental health emerged as the most common risk factors. Due to methodological limitations in the studies included, further research is necessary. It is essential to use clinical samples, objective measures, and consistent conceptualizations to contribute to a better understanding of problematic social media use as well as its mechanisms and effects.
