背景：糖尿病患者和社会经济地位较低的人很难坚持饮食建议。需要实用和有效的工具来评估自我管理行为，以帮助评估针对个别患者或人群需求的干预措施。本研究利用公私合作改善糖尿病教育试验的数据，检验了一份包含11个项目的个人糖尿病问卷（PDQ-11）的心理测量特性。方法：来自田纳西州中坎伯兰地区10个安全网初级保健诊所的2型糖尿病患者（n = 411）完成了PDQ-11、糖尿病自我护理活动摘要（SDSCA）、感知糖尿病自我管理量表（PDSMS）和依从性补充和药物治疗量表（ARMS）。通过统计分析，探讨了PDQ-11量表的子量表结构及其内部一致性和效度。结果：PDQ-11的探索性因子分析揭示了四个成分（Cronbach's alpha = 0.50 ~ 0.81）：饮食行为问题；饮食决策信息的使用；限制卡路里的摄入;活动和锻炼。饮食行为问题和饮食决策信息的使用与SDSCA的饮食亚量表有最强的相关性，也与PDSMS和ARMS评分相关（均p < 0.001）。不同的PDQ-11分量表与BMI（卡路里限制活动和运动）和血压（饮食行为问题）相关。结论：PDQ-11是衡量2型糖尿病患者饮食行为的有效指标；它的使用可以帮助提供者为患者量身定制个人营养干预策略。
Background: Patients with diabetes and of lower socioeconomic status 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) using data from the Public-Private Partnership to Improve Diabetes Education trial.Methods: Patients (n = 411) with type 2 diabetes from ten safety net primary care clinics in the Mid-Cumberland Region of Tennessee completed the PDQ-11, 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 subscale structure of the PDQ-11, and the internal consistency and validity of its subscales.Results: Exploratory factor analysis of the PDQ-11 revealed four components (Cronbach's alpha = 0.50 to 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 and were also correlated with the PDSMS and the ARMS scores (all ps < 0.001). Different PDQ-11 subscales were correlated with BMI (Calorie Restriction Activity and Exercise) and blood pressure (Eating Behavior Problems).Conclusions: The PDQ-11 is a useful measure of dietary behaviors in patients with type 2 diabetes; its use may help providers tailor individual nutrition intervention strategies to patients.
