Abstract
Background: The prevalence of anxiety disorders is high in diabetes and low-middle income countries like India. Research has provided evidence about biofeedback effectiveness on stress related psychophysiological parameters. Aims: This study aims to verify the impact of GSR biofeedback relaxation on stress related psychophysiological parameters (galvanic skin resistance, stress and anxiety) among type II diabetes patients with high levels of anxiety. Settings and Design: Materials and Methods: The present study was single blinded randomized controlled trial. Initially 228 patients of type II diabetes were assessed on state trait anxiety inventory (STAI). Seventy participants who were identified as high anxiety with score above percentile of 75 on STAI invited for participation. Patients were randomly divided for biofeedback relaxation and sham-control group. Participants of the biofeedback group received training on how to use the GSR biofeedback device for management of stress parameters for 20 sessions with 30 minute each session. No intervention was made on sham-control group. Both groups were assessed before and after the biofeedback relaxation training programme. The results of the STAI, GSR and the inventory of stress for type II diabetes patients were compared. SPSS 16 version was used for analysis. Results: Biofeedback group reported a significant change in state anxiety (t=5.089; p<0.001), GSR (t=-2.199; P<0.035) and stress (F=46.850;P<0.001) at post test. Control group reported at the same time moderate increase in stress and trait anxiety. These results are consistent with previous studies. Conclusions: Biofeedback relaxation useful technique for manage their stress and anxiety. During an emotional disturbance this may also be helpful to promote overall psychological health. Further research is necessary to determine the long-term effects of GSR biofeedback relaxation and the effects of mood on cortisol among diabetes patients.
