Introduction: Type II diabetes is an illness that is associated with the severity of the lifestyle and it has very strong behavioral and emotional component as far as some experts considered as a behavioral issue. The aim of this study was to determine the effective- ness of cognitive therapy in reducing glycated hemoglobin patients with diabetes.

Materials and methods: The study was a quasi-experimental type and research project were the two groups of experimental group and control group, along with pre-test, post-test and follow-up. The statistical population were includes all patients with type II diabetes in the range of 25 to 45 years old age that have treated in the Ganjaviyan hospital diabetes clinic and one year of their dia- gnosis should past. We used an available sampling method and sample size was 40 patients and the replacement of the subjects in the intervention group and the control group was randomly. The sample of individuals was selected based on the entry-exit criteria (age 25 to 45 years old, the lack of any obvious mental disorder, the passage of one year since diagnosis of type II diabetes). Then both groups were evaluated before therapeutic intervention, in the next stage therapeutic intervention was carried out on experimental group of cognitive therapy in group method. Meetings are held weekly for 2 hours (ten sessions). The control group did not receive the thera- peutic intervention in a group. So, both groups were evaluated with the use of post-test and then after three months re-evaluation was conducted as a follow-up to the amount of the effectiveness of independent variables (therapeutic intervention in a group) on the dependent variable (grades and following) will be measured.

Results: The results of the Covariance analysis showed that cognitive therapy cause reduction of blood sugar (HbA1c) in the experimental group in the post-test and following stage.

Conclusions: Training cognitive therapy can result in blood sugar control (HbA1c) in patients with type II diabetes. So, it is recommended that the presentation of these trainings beside other medical interventions is as a part of comprehensive treatment and care of diabetes.
