Purpose:
Patientswithdiabetesandlowliteracyandnumeracy
skills have difficulty adhering to dietary recommendations.
Practical and effective tools assessing self-management
behaviors are needed to help evaluate interventions tailored
to the needs of individual patients or population groups. This
study examined the psychometric properties of a short 11-
item version of the Personal Diabetes Questionnaire scale
(PDQ-11) among patients with Type 2 diabetes.
Design Methods:
Participants (n=411) completed the PDQ-
11 (English or Spanish version), the Summary of Diabetes
Self-Care Activities (SDSCA), the Perceived Diabetes Self-
Management Scale (PDSMS), and the Adherence to Refills
and Medications Scale (ARMS). Statistical analyses were
conducted to explore the structure of the PDQ-11, and its
internal reliability and validity.
Results:
Participants were 64% non-Hispanic whites;
18% non-Hispanic blacks; 24% Hispanics; with mean age,
49.3±9.4 years; mean education of 11.2±3.3 years; mean
BMI, 35.8±8.9 kg/m2; and A1C, 9.6%±2.1. Factor analysis of
the PDQ-11 revealed four components (items loading >0.40;
cronbach's α=0.50 - 0.81): eating behavior problems; use of
information for dietary decision making; calorie restriction;
and activity and exercise. eating behavior problems and use
of information for dietary decision making had the strongest
associations with the diet subscales of the SDSCA; general
diet (rs=-0.29 and 0.31, respectively); specific diet (rs=-
0.20 and 0.19, respectively) and were also correlated with
the PDSMS and ARMS scores (all ps<0.001). Different PDQ-
11 subscales predicted BMI (Calorie Restriction, β = 0.17,
p<0.01; and activity and exercise, β=-0.17, p<0.01); diastolic
blood pressure (eating behavior problems, β =-0.14, p<0.01)
and systolic blood pressure (Eating Behavior Problems, β
=-0.17, p<0.01).
Conclusion:
The PDQ-11 is a valid measure of dietary
behaviors in patients with type 2 diabetes; its use may help
to tailor individual nutrition intervention strategies
