The patients had a mean serum glucose of 172.8 mg/dl and a mean HbA1c of 9.19%. After six months, glucose and HbA1c values decreased drastically in patients without psychological disorders and also in patients with mixed disorder; while in the cases in which they presented anxiety there was a slight decrease and in depression, after six months they maintained practically the same levels with HbA1c 9.2% at the beginning and 9.1% in the second measurement.
