Diet Adherence. The diet subscale of the Summary of Diabetes Self-Care Activities
questionnaire (SDSCA) is a standardized measure of diet adherence in diabetes (Toobert,
Hampson, & Glasgow, 2000). Response options range from 0 to 7 to correspond to the
number of days in 1 week. The mean score represents the frequency of adhering to diet
recommendations in the past 7 days.
