Initially developed by the DCCT Research
Group and later modified by Ingersoll and
Marrero (9), the Diabetes Quality of Life:
Youth (DQOLY) scale consists of three subscales:
17-item Diabetes Life Satisfaction
scale; 23-item Disease Impact scale; and
11-item Disease-Related Worries scale (9).
Cronbach's a for each scale in psychomet ric testing by the authors was as follows:
Satisfaction, 0.85; Impact, 0.83; and Worries,
0.82. Each item is answered in a 5-
point Likert scale, so that total scores can
range from 17 to 85 in the Satisfaction
scale, 23 to 115 on the Impact scale, and
11 to 55 on the Worries scale, with higher
scores indicating lower quality of life on the
Impact and Worries scales, and higher life
satisfaction on the Satisfaction scale. The
authors reported that all three scales were
associated with adolescent's self-rated
health status, but that DQOLY scale scores
were not correlated with HbAx values.
