A cross-sectional design was employed, with data collected from 217 undergraduate students (from an initial sample of 250) using validated questionnaires. Data were analyzed using partial least squares structural equation modeling (PLS-SEM) to evaluate direct and indirect relationships. The key findings indicate that BSC has an indirect, relevant, and significant negative effect on Dsym (H5) (β = -0.201, 95% CI [-0.266, -0.216]) through six routes, involving enhanced self-esteem and reduced academic stress. The model highlights self-esteem as a critical mediator between social capital and mental health outcomes. With strong predictive validity (R² ≥ 0.1, Q² > 0, PLS-SEM RMSE < LM), the study provides a framework for potential interventions.

This study investigated demographic, cognitive, and subjective influences on various arithmetic skills throughout adulthood, including both younger and older individuals. In total, 134 adults aged 20-68 completed computerized tasks assessing simple calculations, exact and approximate complex calculations, and arithmetic principles, alongside neuropsychological testing and self-ratings on math anxiety, math self-concept, attitudes toward mathematics, and the frequency of engagement with numbers. The results indicate that accuracy varied by task, with approximate calculations being the most challenging. Self-ratings showed low math anxiety but moderate-to-high math self-concept, positive attitudes, and moderate engagement with numbers. Age correlated only with arithmetic principles; however, interference inhibition and engagement with numbers, not age, best predicted performance. Executive functions correlated solely with approximate calculations and arithmetic principles, while subjective measures were related to all arithmetic tasks. The regression analyses indicate strong interrelationships, particularly among calculation tasks. The findings highlight the multifaceted nature of arithmetic competence and suggest it remains stable in adulthood, with age-related declines only evident in arithmetic principles, likely due to declining executive functions.</p>","PeriodicalId":30631,"journal":{"name":"European Journal of Investigation in Health Psychology and Education","volume":"15 5","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12110183/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144152107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
