effectiveness of cognitive therapy based on mindfulness on self-efficacy and weight loss in patients with diabetes type 2

In daily life, cognitive therapy is one of the skills that can be taught to increase the levels of self-efficacy and weight loss. this study was done to evaluate the effectiveness of cognitive therapy based on mindfulness skills in promoting self-efficacy and self-management in patients with diabetes type 2 in the salas city of kermanshah province. the study method was quasi-experimental with pre-test-post-test and the control group. the statistical population of the study was all patients with diabetes type 2 in salas city of kermanshah province. 30 participants were selected using convenience sampling and randomly assigned to either the experimental or control group. then, 8 sessions of cognitive therapy and self-management were conducted twice a week, each session lasting 120 minutes for the group test. after completing the training and after one month, the post-test was performed simultaneously and under the same conditions for both experimental and control groups. data were analyzed by multivariate analysis of covariance (mancova) with spss 24 software. results of analysis of covariance on post-test scores showed a significant difference between cognitive therapy and control groups in self-efficacy and weight loss variables (p-value< .05). the effect size indicates that about 85% of the variance of the self-efficacy score and about 77% of the variance of the weight loss score is explained by the difference between the two methods. therefore, cognitive therapy training is effective in the self-efficacy and weight loss of diabetic patients.
