Background and purpose: Obesity has a negative effect on women’s psychological health. This study aimed to determine the effectiveness of mindfulness-based stress reduction training (MBSRT) on emotional regulation and quality of life of obese women.

Materials and Methods: The present study was a quasi-experimental study with a pre-test-post-test design and a follow-up with a control group. The statistical population of the study included all women with grade 1 obesity (calculated by body mass index) who referred to obesity and nutrition specialists and clinics in Tabriz (12 clinics) in fall 2023 and winter 2024. A total of 30 people were selected by convenience sampling method and randomly assigned to two experimental and control groups (15 people each). The experimental group received group-specific training in eight 90-minute sessions, while the control group received no training. Both groups completed the Gratz and Romer difficulties in Emotion Regulation Scale and Quality of Life Questionnaires before, after, and 3 months after the intervention. The data were analyzed using repeated measures analysis of variance.

Results: The results showed that MBSRT improved emotion regulation and quality of life in obese women at post-test compared to the control group (P<0.001), and this effect was sustained at follow-up (P<0.001).

Conclusion: MBSRT can probably improve emotional regulation and quality of life in obese women.
