Abstract

In order to assess satisfaction with treatment using oral hypoglycemic agents among patients with type 2 diabetes mellitus, we developed the Oral Hypoglycemic Agent Questionnaire (OHA-Q), a patient-administered questionnaire composed of 20 questions. We enrolled 597 outpatients with type 2 diabetes mellitus who had been treated with a single oral hypoglycemic agent for 1 month or longer at 45 institutions in Japan. Their physicians provided background information on the patients, etc., in the physician-filled forms, and the patients answered both OHA-Q and the Diabetes Treatment Satisfaction Questionnaire (DTSQ) twice in 1 week. After patients with incomplete forms, etc., had been excluded, statistical analyses were performed on 483 patients for the validity assessment and on 419 patients for the reproducibility assessment. Based on factor analysis of the OHA-Q item scores, a simple structure was obtained by three-factor varimax rotation, and three subscale scores were identified as the “treatment convenience score,” “somatic symptom score” and “satisfaction score.” All intraclass correlation coefficients for the subscale scores were 0.7 or higher, showing high reproducibility. A correlation of 0.4 or higher was observed between the subscale scores and the DTSQ satisfaction score. Moreover, an expected association was observed between the subscale scores and patient background factors. Based on these results, OHA-Q may have adequate reproducibility and validity as an assessment scale for satisfaction with treatment using oral hypoglycemic agents in patients with type 2 diabetes mellitus.
