Model 1: regression included gender, past history of depression, hypertension, insulin user, exercise, body mass index (BMI), and glycaemic control (HbA1c). Model 2: included model 1 plus psychological measure. ∗Psychological measure was PAID. ∗∗Psychological measure was PHQ-9. PHQ-9: Patients Health Questionnaire Nine; PAID: Problem Area in Diabetes; BMI: body mass index.
