the effectiveness of dialectical behavior therapy and mindfulness-based cognitive therapy on cognitive components (cognitive fusion, cognitive avoidance and cognitive flexibility) and oxidative stress in women with type 2 diabetes

Aim: The aim of this study was to compare the effectiveness of dialectical behavior therapy and mindfulness-based cognitive therapy on cognitive components (fusion, avoidance and cognitive flexibility) and oxidative stress in women with type-2 diabetes. Methods: The research method was quasi-experimental with pre-test/post-test design and control group on 60 female patients with type-2 diabetes referred to public health centers in Birjand (Iran) during 2016. Participants in the two experimental groups (40 subjects) and one control group (20 subjects) were recruited through convenient sampling and the tests administered randomly. Data collection tools included Gilander et al. (2014) Cognitive Integration Questionnaire, Sexton and Ducas (2008) Cognitive Avoidance Questionnaire, and Dennis and Vanderwall (2010) Cognitive Flexibility Questionnaire. Also, the experimental group was presented with Fendaic (2017) Dialectical Behavior Therapy protocol, Ghahari Dialectical Behavioral Therapy (2016) and cognitive therapy based on Seagal, Williams & Tizdell (2002) mindfulness, which was not presented to the control group. Data analysis was performed using univariate and multivariate analysis of covariance. Findings: The results showed that dialectical behavior therapy, in comparison with mindfulness-based cognition therapy on reducing cognitive components, and oxidative stress and mindfulness-based cognitive therapy on thought-suppression and emotional components in patients with diabetes is effective (P <0.05). Conclusion: According to the findings, dialectical behavior therapy can be used as a complementary therapy to improve the emotional and cognitive components of diabetic patients compared to mindfulness-based cognitive therapy.
