The results of the analysis of covariance showed that at the level of p < .05 there was a significant difference in the variables of psychological well- being and cognitive emotion regulation between the experimental and control groups. In psychological well-being (F = 174.30, p < .05), and effect size equal to 0.87, in adaptive cognitive emotion regulation (F = 99.20, p < .05) and effect size (0.80), in cognitive emotion regulation incompatibility (F = 93.87, p < .05) and effect size (0.79) and a significant difference at the significance level of p < .05 were observed between the experimental groups and the control group. Therefore, mindfulness training had a significant effect on psychological well-being and cognitive emotion regulation of people with depressive disorder.
