Abstract
Objective To evaluate the clinical effect of group cognitive behavioral therapy on blood glucose levels, anxiety and depression in patients with type2 diabetes mellitus. Methods Ninety three patients with type 2 diabetes mellitus were recruited and randomly divided into intervention group (n=48) and control group (n=45). Both groups received diabetes health education, patients in intervention group received additional group cognitive behavioral therapy. The glucose tolerance, glycosylated hemoglobin A1c were measured; the HAMA(Hamilton Anxiety Scale)scores, HAMD(Hamilton Depression Scale)scores and CSQ (Coping Styles Questionnaire)scores in patients were analyzed before and 6 months after treatment. Results After 6-month treatment the fasting blood glucose(6.33 mmol/L vs. 5.94 mmol/L), 1 h postprandial plasma glucose(12.40 mmol/L vs. 11.46 mmol/L), 2 h postprandial plasma glucose (10.24 mmol/L vs. 9.13 mmol/L), A1c(6.31% vs. 6.07%)in intervention group were decreased significantly, compared to baseline values (all P<0.05). The HAMA total score(9.98 vs. 8.14), somatic anxiety (3.98 vs. 3.48), psychic anxiety(6.00 vs. 4.67), HAMD total score(10.74 vs. 6.93), anxiety somatic(5.02 vs. 3.26), block(2.24 vs. 1.38)and sleep disorders(2.40 vs. 1.40)in intervention group were all decreased significantly(P<0.01 or 0.05). There were significant differences in HAMA total score(8.14 vs. 9.15), HAMD total score(6.93 vs. 9.33), anxiety somatic(3.26 vs. 4.38), block(1.38 vs. 1.98)and sleep disorders(1.40 vs. 2.03)between the intervention group and control group(P<0.01 or 0.05). And the negative coping style scores in intervention group was also lower than that of the baseline(26.74 vs..29.43). Conclusion The group cognitive behavioral therapy combined with diabetes health education for patients with type 2 diabetes mellitus may improve the glucose metabolism and depression and anxiety status of patients.
