Objective: This study aimed to examine the effects of a Mindfulness-Based Community Renewal (MBCR) intervention on residents’ mindfulness, empathy, and sense of community within an urban renewal context. Methods: Fifty community residents were randomly assigned to either an experimental group receiving four biweekly mindfulness workshops over eight weeks or a control group receiving standard planning workshops. Measures of mindfulness (MAAS), empathy (TEQ), and sense of community (SCI) were administered before and after the intervention. Repeated-measures ANOVA was conducted to analyze differences between groups over time. Results: The experimental group showed significant improvements in empathy and sense of community compared with the control group, while gains in mindfulness were modest. Group × time interaction effects were significant for empathy and sense of community but not for mindfulness. Conclusions: Integrating mindfulness-based practices into community engagement appears to enhance relational and collective outcomes among residents. Although mindfulness itself showed limited short-term change, the intervention contributed to increased empathy and stronger community bonds. These findings suggest that MBCR may be a feasible strategy to support inclusive and resilient community renewal processes. Future studies should employ larger samples and longer follow-up periods to further validate these results.
