Mindfulness-Based Self-Compassion and vagal nerve stimulation were administered to the Intervention I group. Mindfulness-Based Self-Compassion intervention is a manualized course that includes meditation, relaxing movement, and breathing. A certified Mindfulness-Based Self-Compassion instructor will teach the courses in a group-based format for 90 minute sessions, once per week for three weeks.

Vagal nerve stimulation was administered to all participants in both groups using the on-invasive Auricular Vagus Nerve Stimulation device. The stimulation was biphasic, with a frequency of 10 Hz and a pulse width of 300 μs in Modulation mode. Current intensity was adjusted by attaching the device to the participant's right or left ears, ensuring that they felt the current comfortably, and maintaining a constant level. Stimulation sessions occurred every 3 weeks, with non-invasive auricular vagus nerve stimulation applied for 20 minutes per session over a period of 3 days.

Only vagal nerve stimulation was administered to the Intervention II group. Vagal nerve stimulation was administered to all participants in both groups using the Non-invasive Auricular Vagus Nerve Stimulation device.

Current intensity was adjusted by attaching the device to the participant's right or left ears, ensuring that they felt the current comfortably, and maintaining a constant level. Stimulation sessions occurred every 3 weeks, with non-invasive auricular vagus nerve stimulation applied for 20 minutes per session over a period of 3 days.

The intervention has its roots in meditations and yoga practices. However, it is independent of religious purpose or affiliation.The weekly sessions include a range of mental and bodily practices, including awareness of

Heart Rate Variability (HRV) refers to the variation in the time interval between heartbeats. It is a measure of the slight differences in timing between successive heartbeats, often measured in milliseconds. HRV is regulated by the autonomic nervous system, which controls involuntary bodily functions, including heart rate.

Psychological Resilience Scale for Adults: The scale consists of 33 items; it includes 6 sub-dimensions: The structural style (3,9,15,21) and perception of future (2,8,14,20) subdimensions were measured by 4 items each, the family cohesion (5,11,17,23,26,32), perception of self (1,7,13,19,28,31,), and social competence (4,10,16,22,25,29) subdimensions were measured by 6 items each, and the social resources (6,12,18,24,27,30,33) sub-dimension was measured by 7 items. The score that can be obtained from the scale varies from 33 to 165.
