Abstract
OBJECTIVE: This study examined the effectiveness of a short video app-guided Loving-Kindness Meditation (LKM) intervention in enhancing interpersonal mindfulness, empathy, interdisciplinary collaboration, affective states, and workplace well-being among working professionals. METHODS: A randomized controlled trial (RCT) was conducted with 100 full-time employees (aged 25-60), randomly assigned to an intervention group (n = 50) or a control group (n = 50). The intervention group completed daily 3-min LKM sessions for 4 weeks via a secure short video app, while the control group received no intervention. Validated psychological scales were administered at baseline and post-intervention, including the Interpersonal Mindfulness Scale (IMS), Empathy Scale (ES), Interdisciplinary Collaboration Scale (ICS), Positive and Negative Affect Schedule-Short Form (PANAS-SF), and Workplace Well-being Scale (WWS). A 2 × 2 mixed ANOVA was used to assess group × time interaction effects. RESULTS: Significant group × time interaction effects emerged for all six outcomes. Compared with controls, the intervention group showed greater increases in interpersonal mindfulness (F = 7.789, p = 0.006, η(2) = 0.038), empathy (F = 9.831, p = 0.002, η(2) = 0.048), collaboration (F = 4.832, p = 0.038, η(2) = 0.022), and positive affect (F = 8.580, p = 0.004, η(2) = 0.042), along with reduced negative affect (F = 10.169, p = 0.002, η(2) = 0.049) and improved workplace well-being (F = 5.660, p = 0.018, η(2) = 0.028). CONCLUSION: These findings demonstrate that short video-based LKM is a feasible and effective digital intervention for cultivating prosocial qualities, emotional regulation, and psychological well-being in workplace settings. The study supports integrating compassion-based practices into organizational wellness initiatives to promote employee functioning and workplace harmony.
