Hazardous substance use (including substance use) is associated with a wide range of harmful consequences, especially when these hazardous users are caregivers. However, previous studies have led scholars to question the robustness of the association between caregivers’ hazardous substance use and child maltreatment perpetrated by those substance-abusing caregivers. Despite some related meta-analyses previously, researchers have examined different substances separately with limited eligible studies ( k _s < 13). Given that, with 54 estimates from 50 studies ( k = 54), we conducted a meta-analysis ( N = 736,881) to examine the overall association between caregivers’ hazardous substance use and child maltreatment, and subgroup analyses to test potential moderators. Results showed a small-to-medium overall effect, Pearson’s r = .197, 95% CI [0.159, 0.235]. Subgroup analyses have not identified significant differences in the overall association across different caregiver roles of hazardous substance users, types of child maltreatment, types of consumed substances, reporters of hazardous substance use and child maltreatment, sample sizes, and studies with different quality scores. In sum, our findings indicate that the association between caregivers’ hazardous substance use and child maltreatment is relatively small but stable across multiple boundary conditions. While high heterogeneity ( I ² = 99.20%) cannot by itself negate the stability and interpretability of our results, it indeed calls for more cautious interpretation after taking this point into account. Our findings also have implications for future research and interventions to mitigate child maltreatment.

Purpose: This study examines how five East Asian jurisdictions have developed policies and service delivery systems to address family polyvictimization (FPV). Method: A scoping review was conducted using PsycINFO, Sociological Abstracts, Scopus, and various government sources. Fifty-seven sources published between 2000 and 2025 were synthesized using a four-dimensional analytical matrix. Results: Two primary institutional typologies emerged. Japan and South Korea deploy a Multi-Agency Collaborative Approach (Model 1) , which yields high domain-specific expertise but suffers from fragmented oversight. Taiwan and Hong Kong utilize a Centralized and Integrated Approach (Model 2) , characterized by coordinated multidisciplinary platforms. Chinese Mainland features an Emerging Approach that heavily relies on outsourcing public welfare but lacks centralized coordination mechanisms. Discussion: These findings advance the conceptual modeling of FPV by highlighting the trade-offs between professional specialization and structural integration. To address FPV, protection systems must embed standardized protocols, proactive family-wide screening, and stronger interagency coordination.

Early online safety habits shape later behaviors, and core capabilities remain protective across ages, warranting population‑wide approaches. Families function as cross‑age safety systems with bidirectional learning and shared social learning mechanisms across cohorts, suggesting transferable, lifespan‑spanning intervention principles. This umbrella review synthesizes 66 systematic reviews and meta-analyses on digital interventions for cyberbullying and online harm across the lifespan. A comprehensive search following the PRISMA structure was conducted using databases including PubMed, PsycINFO, MEDLINE, ERIC, Sociological Abstracts, Social Service Abstracts, Scopus, EMBASE, for reviews published through December 31, 2025. Stronger effects were observed for multi‑component, theory‑driven programs that combine easy‑to‑hard practice, timely feedback, and reminders. At the micro level, university bystander programs and media literacy showed the largest gains, particularly in multi‑session formats. At the meso level, organizational trainings produced immediate improvements with boosters and policy supports; community and clinical delivery improved reach for older adults when paired with assisted reporting. At the macro level, platform warning messages and pause‑and‑verify prompts offer scalable benefits, and gendered risk patterns and increasing campus fraud prevalence underscore the need for tailored scenarios and just‑in‑time prompts. Policy and practice should adopt a family‑based lens, integrate boosters and cross‑sector coordination. Future research should standardize behavioral outcomes, use pragmatic and hybrid designs with longer follow‑up, and expand to underserved settings and emerging threats.

Family context plays a pivotal role in shaping children and adolescents, and child maltreatment in the family context serves as a notable contributor to their psychological and behavioral problems, including bullying perpetration. Although many reviews have synthesized the risk factors for bullying perpetration, little attention has been devoted to family-specific maltreatment. Additionally, prior syntheses often combined bullying perpetration and victimization, potentially obscuring the distinct psychological mechanisms between these two processes. To address these gaps, we conducted a meta-analysis with 52 estimates from 50 eligible studies to examine the association between child maltreatment in the family context and bullying perpetration by victimized children and adolescents. The results revealed a relatively medium overall effect for the aforementioned relationship, Pearson's r = .241, 95% CI [0.196, 0.284]. We also found that this effect stays consistent across the gender proportion of participants, development stage of participants' regions (developed regions vs. developing regions), regions where the studies were conducted, types of maltreatments, maltreatments perpetrators, research designs, sample sizes, and publication year. Comparatively, studies in which parents (vs. victimized children) serve as the maltreatment reporters yielded smaller effect sizes. In sum, our findings underscore the robust association between child maltreatment in the family context and bullying perpetration by victimized children and adolescents and highlight the factors that may influence the overall relationship. We also outline implications for future research and practice, including updating prevention and intervention strategies to reduce bullying among children and adolescents.

Intimate partner violence (IPV) is a major public health issue associated with adverse mental health outcomes, including suicidal ideation. However, limited research has examined the correlates of suicidal ideation among shelter-seeking women. This study analyzed data from a clinical sample of 597 women who sought services from three major shelters for battered women in Hong Kong between 2020 and 2024. Among the participants, 48.1% reported suicidal ideation, and 21.3% were classified as having high-risk suicidal ideation based on its frequency in the preceding year. Logistic regression analyses identified several factors associated with high-risk suicidal ideation across victim, perpetrator, and family domains. Among participants' characteristics, lower educational attainment, being divorced or separated, chronic illness, and diagnosed mental illness were significantly associated with high-risk suicidal ideation. Perpetrator-related factors, including histories of childhood abuse or neglect, jealousy, and depressive symptoms, were also significantly associated with high-risk suicidal ideation. In addition, family members' chronic illness, mental illness, and gambling problems were associated with high-risk suicidal ideation. These findings underscore the importance of holistic and trauma-informed approaches in shelter settings that consider individual, relational, and family-level circumstances. Future research should further examine these associations over time and explore ways to strengthen shelter-based mental health support for this vulnerable population.

BACKGROUND Cyberbullying threatens children’s mental health and social well‑being. Traditional programs often operate in isolation that fail to engage parents and teachers. Immersive, gamified simulations offer a novel approach by enabling multi-stakeholder participation within a unified framework. OBJECTIVE This study evaluated the efficacy of a gamified cyberbullying prevention education platform Game-based Intervention for School- and Cyberbullying for Children (GISCC 2.0) and examined dose-response relationships between game engagement and outcomes. METHODS A three-arm randomized controlled trial design was employed with 222 students randomly assigned to: Group A (Student+Parent Game, n=72 dyads), Group B (Student Game Only, n=76), and Group C (Control, n=74). 6 teachers also participated with the teacher-specific game modules. Primary outcome included internet self-efficacy, and secondary outcomes included coping intention, parent-child communication, and perceived peer pressure. Process data were measured via completed storylines and achieved scores in the game. Analyses included intention-to-treat ANCOVAs controlling for baseline scores, gender, and age, with dose-response analyses for engagement. RESULTS Both intervention groups showed significantly greater improvements than controls in internet self-efficacy (η²=.23, p<.001) and coping intention (η²=.17, p<.001), with no differences between the two intervention conditions. Medium effects were also found for parent-child communication (η²=.07, p=.001). No significant effect was observed for perceived peer pressure. Game storylines completion correlated with post-test self-efficacy (r=.28, p<.01) and coping intention (r=.26, p<.01). Parents demonstrated a large increase in coping intention (d=1.86), and teachers showed positive trends across all measures. CONCLUSIONS The gamified intervention robustly enhanced cyberbullying-related coping and confidence among students, primarily through direct digital engagement, with additional parallel benefits for parents and teachers. GISCC 2.0 demonstrates a scalable, digitally integrated framework for schools to address cyberbullying, allowing flexible home and staff involvement while prioritizing high-fidelity student engagement for maximal impact.

Cyberbullying victimization among adolescents is an escalating concern, necessitating deeper insights into coping strategies. This study aims to uncover distinct patterns of coping strategies and to examine how prior cyber-victimization, private information disclosure (self-disclosure, disclosure perpetration, disclosure victimization), and social capital (online and offline) relate to these empirically derived profiles. A sample of 1,716 Chinese secondary students (mean age = 14.62 years; 44.5% male) from public ( n = 1,132) and vocational ( n = 584) schools completed the survey. Using latent profile analysis (LPA), we identified three distinct profiles of coping strategies: (1) Maladaptive and Avoidant , (2) Moderate and Cognitive-Reframing , and (3) High Engagement and Flexible . R3STEP Multinomial Logistic Regression results showed that adolescents in the Maladaptive and Avoidant group had the highest scores in disclosure of private information, cyberbullying victimization, and online social capital, alongside the lowest scores in offline social capital. Adolescents in the Moderate and Cognitive-Reframing group reported the highest levels of offline social capital. Those in the High Engagement and Flexible group reported the lowest scores of all adversities. This profiling offers significant advantages over traditional typologies by providing a data-driven method for identifying coping profiles and capturing the dynamic interactions of multiple factors within individuals. This research provides valuable insights for designing more targeted interventions that address the specific needs of each group, particularly for adolescents with avoidant tendencies.

Children with disabilities are at heightened risk of violence, but existing meta-analyses rarely explore the impact of multiple disabilities and polyvictimization. This study updates global estimates and investigates how different disability types intersect with victimization risk. Databases of literature published on or before July 2024 were searched. Inclusion criteria required studies to (a) involve participants aged ≤18 years with professionally diagnosed disabilities, (b) report comparative data with non-disabled peers, and (c) present quantitative measures of victimization. A total of 44 publications (1,734,560 children) met the inclusion criteria and were included in the analysis. Random-effects models estimated pooled odds ratios ( OR s), with subgroup analyses conducted. The overall OR was 2.04 (95% CI [1.84, 2.52]). Polyvictimization was significantly associated with visible disabilities ( OR = 2.04 [1.42, 2.93]), invisible disabilities ( OR = 3.16 [1.76, 5.70]), and multiple disabilities ( OR = 4.17 [2.25, 7.74]). Children with multiple disabilities had markedly high risk for physical violence ( OR = 4.07 [2.12, 7.81]). Subgroup analyses showed that children in secondary school ( OR = 4.16 [2.83, 6.11]) experienced the highest risks for polyvictimization. Child self-reports yielded the highest OR s ( OR = 4.16 [2.82, 6.11]) compared to mixed or parent reports. Children with invisible and multiple disabilities face disproportionate risks, particularly for polyvictimization. These findings underscore the need for early identification and tailored prevention efforts. Future research should address definitional inconsistencies and expand representation across regions and populations.
