Background <p>Cyberbullying, as an extension of traditional bullying in cyberspace, has proliferated rapidly in recent years alongside the advancement of information technology. Concerning the sources of cyberbullying, many researchers argue that it is associated with Psychological well-being, while some scholars hold the opposite view. To resolve this controversy, this study investigates the correlation between Psychological well-being and cyberbullying.</p> Methods <p>To explore the correlation between Psychological well-being and cyberbullying, this study conducted a meta-analysis of 173 samples from 115 articles published between 2009 and 2025. This study used the meta-analysis method of correlation coefficient. It means that we use Pearson product-moment correlation coefficient r as variable data of effect size.</p> Results <p>This study divides PWB into positive indicators (PI) and negative indicators (NI). Findings confirmed significant correlations between both PI/NI and cyberbullying, indicating a stable relationship between the two PWB categories and cyberbullying. Additionally, culture,gender, grade and year were found to significantly moderate the relationship between PWB and cyberbullying.</p> Conclusions <p>The results demonstrated that PI was negatively correlated with cyberbullying, with this relationship influenced by year, grade, culture and gender. NI showed a positive correlation with cyberbullying, modulated by culture and year. Multi-sample results are more reliable than single-sample ones, providing a solid foundation for future research on Psychological well-being and cyberbullying.</p>
