Impact of Group Reality Therapy on Treatment Adherence and Health Indicators in Patients with Type 2 Diabetes Mellitus: A Randomized Controlled Trial

Background: The use of non-pharmacological therapies is important in reducing the complications and consequences of diabetes. Objectives: This study aimed to determine the effect of group reality therapy on adherence to treatment regimens and health indicators in patients with type 2 diabetes. Methods: This randomized controlled trial was performed on 60 patients with diabetes who were referred to Amir Al-Momenin Hospital in Ahvaz. Patients were randomly assigned to either the intervention group (N = 30) or the control group (N = 30). Both groups completed health indicator tests, questionnaires on demographic and clinical information, perceived adherence to the treatment regimen, and the Perceived Stress Scale. The intervention group received reality therapy training, which consisted of 10 sessions of 45 minutes each (one session per week) over 2 months, delivered through lectures and face-to-face training sessions. The control group received only routine hospital interventions. The collected data were then analyzed using a one-way t-test and one-way analysis of variance (ANOVA). Results: Twenty-seven patients in the intervention group and 27 in the control group completed the study. After analyzing the data, it was revealed that the mean age of the patients in the control group was 55.30 ± 7.95, while it was 51.96 ± 10.55 in the intervention group. Findings showed that scores for the dimensions of adherence to the treatment regimen in the intervention group significantly increased compared to the control group (P < 0.001). Additionally, the mean health indicators in the intervention group showed a significant decrease compared to the control group (P < 0.001). Moreover, the mean blood sugar level of patients in the intervention group decreased from 229.63 ± 98.76 to 123.59 ± 42.03. Likewise, the level of glycosylated hemoglobin and blood cholesterol significantly decreased from 8.19 ± 2.09 to 6.11 ± 1.86 and from 176.52 ± 51.53 to 146.22 ± 34.68, respectively. Conclusions: A reality therapy training program can be effectively used to increase treatment adherence and improve health indicators in patients with type 2 diabetes.
