Diabetes Diet-Related Quality-of-Life Scale
One of the most unpalatable aspects of life with diabetes is dietary
restrictions that trade glycemic control for flavor and satisfaction. In order
to help study quality-of-life issues related to diabetes care, a group of
investigators at the University of Tokyo developed and validated an assessment
scale to measure the influence of diet therapy.
The Diabetes Diet-Related Quality-of-Life (DDRQOL) scale was adapted by the
authors from an existing scale developed by one of them to measure dietary
satisfaction among patients with kidney disease. The DDRQOL scale required
slight modification, changing terminology from "protein
restriction" to "energy restriction" in several places.
The instrument consists of eight subscales that solicit information about
satisfaction with diet; the psychological burden of diet therapy; the physical
burden of diet therapy; the perceived merits of diet therapy; general
perceptions of diet; and restriction of social function, vitality, and mental
health.
Investigators validated the DDRQOL instrument on 236 middle-aged patients
with type 2 diabetes, associating results with the standard questionnaire
short form 36 (SF-36). "The DDRQOL was found to have a reasonable degree
of reliability and validity," the authors concluded. "Therefore,
its application for the assessment of patients' needs and the evaluation of
intervention in the form of diet education in diabetic patients is
awaited."
