Comparison of the Effectiveness of Combining Acceptance and Commitment-based Therapy and Mindfulness-based Stress Reduction Therapy with Neurofeedback on Anxiety Sensitivity and Perceived Stress in People with Type 2 Diabetes

The present study is a quasi-experimental study with an inter-intra subject design aimed to determine the effectiveness of combining acceptance and commitment-based therapy and mindfulness-based stress reduction therapy on anxiety sensitivity and perceived stress in people with type 2 diabetes. The sample consisted of 45 patients with type II diabetes purposefully selected from patients referred to laboratories in Mahshahr city. After matching, the patients were randomly assigned to 3 groups of 15 patients and the experimental groups received their group interventions in 8 sessions of psychological therapy and 10 sessions of individual neurofeedback training and the control group did not receive any intervention. Pre-test, post-test, and 2-month follow-up were performed with Floyd et al.'s (2005) Anxiety Sensitivity Questionnaire and Cohen et al.'s (1983) Perceived Stress Scale. According to the results of SPANOVA analysis, both ACT + neurofeedback and MBSR + neurofeedback were effective in post-test and follow-up stages to reduce anxiety sensitivity and perceived stress. But while the effectiveness of both interventions in reducing anxiety sensitivity was the same, for perceived stress, the effect of MBSR + neurofeedback, both in the post-test and in the follow-up phase, was significantly greater than the effect of ACT + neurofeedback.
