This meta-analysis examines the association between fear of negative evaluation (FNE) and smartphone addiction (SPA), focusing on the indirect association through social anxiety (SA) and potential moderators. This study followed PRISMA 2020 guidelines and was registered in PROSPERO (CRD42024619488). Studies published between January 2010 and June 2025 were systematically searched. A total of 330 empirical studies (334 independent samples; 272,538 participants) were included. One-stage meta-analytic structural equation modeling (MASEM) was used to compare models with the direct FNE to SPA path constrained to zero or freely estimated, and to estimate direct and indirect associations. Moderation was examined using χ2 difference tests. (1) FNE was positively associated with SPA after accounting for SA (β = 0.299, p < 0.001); (2) The estimated indirect association through SA was statistically significant (β = 0.112, p < 0.001) and represented approximately 27.2
The purpose was to examine childhood environmental unpredictability (CUP), longitudinal psychological associations and social support among men in compulsory drug rehabilitation. Four approximately monthly assessments involved 1102 men. CUP was retrospectively assessed at baseline. Robust cross-lagged models adjusted for childhood adversity and baseline characteristics; support moderation and random-intercept analyses were conducted. CUP was associated with initial loneliness (β = 0.297) and intolerance of uncertainty (IU; β = 0.410), with a marginal craving association (β = 0.062, p = 0.051). Loneliness and IU predicted subsequent craving (β = 0.183–0.187 and 0.054–0.066); within-person loneliness associations were also supported (β = 0.096–0.178). The joint continuous-support interaction was significant (p = 0.003), but corrected directional and overall group tests were nonsignificant. Early environments, social connection and uncertainty-related difficulties merit joint attention in rehabilitation assessment. Specific support-buffering pathways require further validation.
With the rapid proliferation of artificial intelligence (AI) tools in higher education settings, graduate students’ patterns of dependency on these tools have become an increasingly important academic concern. This study examined the direct association between academic perfectionism and AI dependency and the serial mediating roles of the impostor phenomenon, academic writing anxiety, self-regulation, and academic procrastination in this association. The study group comprised 626 master’s and doctoral students enrolled at various universities in Türkiye. Findings obtained using a serial mediation model revealed that perfectionism was directly associated with AI dependency and indirectly associated with it through the impostor phenomenon, academic writing anxiety, self-regulation, and procrastination. The findings indicate that graduate students’ patterns of AI use cannot be explained solely as a technological tendency; rather, these patterns are underpinned by anxiety and self-regulatory difficulties fed by perfectionistic cognitions and feelings of inadequacy. The results were discussed with respect to academic advising and graduate education policies, and recommendations for future research were offered.
Mood disorders substantially contribute to non-fatal health loss, and COVID-19 may have altered their trends. Evidence for East Asia post-pandemic is limited. Using GBD 2023 data, we analyzed incidence, prevalence, and YLDs for bipolar disorder, dysthymia, and major depressive disorder (MDD) in five East Asian countries (1990–2023). We assessed age-standardized rates, age-sex patterns, decomposition analyses, SDI associations, and projected burden to 2038 with a Bayesian age–period–cohort model. In 2023, MDD posed the largest burden. From 1990–2023, MDD increased across all countries; bipolar disorder declined in Japan and Korea but rose elsewhere; dysthymia generally declined except in Mongolia. Females had higher MDD and dysthymia burden; bipolar disorder showed country-specific sex differences. Bipolar disorder and MDD generally peaked in adolescence (with notable country-specific exceptions in middle-aged and oldest-old populations), whereas dysthymia affected older ages. Population growth drove absolute increases; epidemiological changes fueled MDD growth. Projections indicate stable bipolar burden, rising dysthymia in China, Japan, and Korea, and mixed MDD trends with persistent sex gaps. Mood disorders remain a growing public health challenge in East Asia, with cross-country heterogeneity, female disadvantage, and age-specific risk peaks, highlighting the need for targeted, context-specific interventions.
Short-form video platforms have grown rapidly, raising concern about short-form video addiction (SVA). Fear of missing out (FoMO) is a widely proposed correlate of problematic social media use, but its association with SVA has not been synthesized. This systematic review and meta-analysis (PROSPERO CRD420261401763) searched Web of Science, Scopus, and PubMed for English-language studies and identified 16 eligible studies (N = 11,804). FoMO–SVA correlations (zero-order, except one latent correlation and one composite of subdimension correlations) were pooled with a random-effects model (REML) and a Knapp–Hartung adjustment, and study quality was appraised with the revised JBI tool for analytical cross-sectional studies. The pooled correlation was positive, r = .494 (95
