Abstract
BACKGROUND: Functional dyspepsia is a common chronic digestive disorder. The purpose of this study was to compare the effectiveness of dialectical behavior therapy and anti-anxiety medication in patients with functional dyspepsia. MATERIALS AND METHODS: The present study was a randomized, controlled clinical trial with sixty patients who were suffering from functional dyspepsia that identified by the ROME III criteria. Patients were divided into three groups by using pre- and posttest design, including Group A (dialectal treatment and pantoprazole), Group B (anxiolytic drug treatment and pantoprazole), and Group C (no intervention, only pantoprazole were used). The Beck Anxiety Inventory and the patient assessment of Gastrointestinal Symptom Severity Index Questionnaire were completed by the patients after receiving the written consent. Finally, the data were analyzed using the Statistical Package for the Social Sciences software version 20. RESULTS: There was a significant improvement in the severity of dyspepsia after intervention in all three groups. The greatest decrease in the severity of functional dyspepsia was observed in the dialectical behavioral therapy group as compared to the other groups (Group A: -15.4 ± 6.61, Group B: -3.85 ± 2.77, and Group C: -7.8 ± 4.02; P = 0.001). Furthermore, the Beck Anxiety Inventory scores were statistically significantly improved in all three groups (Group A: -5.75 ± 2.53, Group B: -7.3 ± 3.19, and Group C: -2.60 ± 1.5; P = 0.001). There was a positive correlation between the change in dyspepsia score and change in anxiety score across different intervention groups (r = 0.55; P < 0.001). CONCLUSION: Dialectical behavioral therapy can be effective in reducing anxiety and improving the dyspepsia symptoms in patients with functional dyspepsia compared to anti-anxiety medication or conventional therapy. Therefore, communication between the physicians and psychologists and psychiatrists can have positive effects on the treatment of these patients.
