New Research Identifies Preferred Survey Instruments for Measuring Medication Satisfaction.

DMSRQ and DMSRQ-SF Are Recommended in Type 2 Diabetes Patients

Lawrenceville, NJ, USA—December 12, 2018—Value in Health, the official journal of ISPOR—the professional society for health economics and outcomes research, announced today the publication of new research showing that the Diabetes Medication System Rating Questionnaire (DMSRQ) and the Diabetes Medication System Rating Questionnaire-Short Form (DMSRQ-SF) are the preferred survey instruments for measuring medication satisfaction in patients with type 2 diabetes (T2D) using oral therapy in clinical trials. The report, “A Systematic Review of Patient-Reported Satisfaction with Oral Medication Therapy in Patients with Type 2 Diabetes,” was published in the November 2018 issue of Value in Health.

Using specific inclusion criteria, the authors identified and evaluated 8 survey instruments designed to measure satisfaction with medication in T2D patients treated with oral therapy:

Diabetes Medication Satisfaction (DiabMedSat)
Diabetes Treatment Satisfaction Questionnaire, status version (DTSQs)
Diabetes Medication System Rating Questionnaire (DMSRQ)
Diabetes Medication System Rating Questionnaire-Short Form (DMSRQ-SF)
Diabetes Tablet Treatment Questionnaire (DTTQ)
Perceptions About Medications for Diabetes (PAM-D)
Satisfaction with Oral Anti-Diabetic Agent Scale (SOADAS)
Diabetes Medication Satisfaction Tool (DMSAT])
Each of the 8 selected instruments was assessed based on several measures: inclusion of patients in instrument development, practicality, breadth and depth of health measures, reliability, validity, and responsiveness. Based on in-depth evaluations, the DMSRQ and DMSRQ-SF met the most review criteria and were recommended for measuring medication satisfaction. The authors note that the DTSQs should also be considered in certain circumstances, and the DTTQ may be of interest in the clinical setting because it may offer the side benefit of improving adherence in patients.

“Historically, there has been limited information in the literature regarding the psychometric properties of medication satisfaction instruments used in patients with diabetes,” said author Yu Wang, Department of Clinical and Administrative Pharmacy, University of Georgia, Athens, GA, USA. “Although the standards we employed here are certainly important and a good starting point, more work is needed to clearly define the most important attributes of satisfaction with medication. The lack of widely accepted standards and the potential for overlap between constructs within instruments further complicate finding an ideal satisfaction instrument.”
