Investigating the Effect of the 6-Week Mindful Self-Compassion Program for Emerging Adults (EYL) on Stress Response, Brain Activity, and Self-Compassion Among Chinese University Students: An Electroencephalogram (EEG) Quasi-experimental Study Using Portab

Résumé

Mindful Self-Compassion (MSC) programs have demonstrated benefits for psychological well-being, yet their neurophysiological mechanisms remain underexplored, particularly in naturalistic settings using portable electroencephalography (EEG). This study examined the effects of a six-week MSC program, Embracing Your Life (EYL), on stress response, brain activity, and self-compassion among Chinese university students. A quasi-experimental design was used with 62 participants (31 in the experimental group and 31 in the control group; mean age = 26.6 years). The experimental group participated in six weekly 1.5-h EYL sessions, while the control group received no intervention. EEG data were collected using a portable headband (channels AF7, AF8) during baseline and post-intervention, involving three meditation tasks: resting state, mindfulness breathing, and a self-compassion break. Power spectral density (PSD) was calculated, and self-reported measures included self-compassion (SCS-SF), perceived stress (PSS), resilience (CD-RISC), mindfulness attention (MAAS), and well-being (SWEMWBS). Generalized estimating equations were used to analyze the data, controlling for baseline differences. The experimental group showed significant improvements in self-compassion (MD =  + 0.28, p = 0.003), mental well-being (+ 1.75, p
