2.1. Patient selection
Patients hospitalized in the Department of Endocrinology of
The First Affiliated Hospital of Xi'an Jiaotong University between
November 2010 and Mar 2011 were enrolled in the
study. The research process had got approval of the ethics
committee of the university. All the patients had provided
informed consents for research participation. The criteria for
inclusion in the study were: 1) patient age between 40 and 70
years with a diagnosis of T2DM according to the World Health
Organization diagnostic criteria [11]; 2) one- to two-year history
of diabetes; 3) glycated hemoglobin (HbA1c) 9%; and 4)
an educational level of at least six years. Patients were
excluded for: 1) disturbance of consciousness, cognitive disorders
or defects in language communication; 2) presence of a
severe acute disease or chronic disease (e.g. severe heart
failure, lung function failure, tumors); or 3) if they were unwilling
to participate in this study. Patients were then
randomly assigned to groups receiving intervention with
either MI or routine diabetes education.
