糖尿病与饮食自我管理能力（PDDC）的一般测量被开发用于评估一个人在糖尿病和饮食自我管理中的自信感和感知行为控制。内部结构，信度和结构效度进行了评价。方法：有2个样本的非裔美国妇女2型糖尿病; 226例患者的开发样本和225例患者的验证样本。因子分析、Cronbach’s系数α和相关分析被用来评估PDDC测量的信度和效度。结果通过因子分析确定了三个分量表：积极能力、消极饮食能力和消极控制。所有分量表的Cronbach α均良好。预测的关系与措施的感知健康能力，自我效能，社会支持，和感知的饮食障碍在很大程度上支持结构验证。结论：本研究提供了初步支持的内部信度和效度的感知糖尿病和饮食能力的措施。需要进一步的研究来确定它在其他非裔美国人2型糖尿病患者样本中的有效性，以及它在评估糖尿病自我管理训练中的临床效用。
PURPOSE General measure of perceived diabetes and dietary competence (PDDC) was developed to assess a person's sense of confidence and perceived behavioral control in diabetes and dietary self-management. Internal structure, reliability, and construct validity were evaluated. METHODS There were 2 samples of African American women with type 2 diabetes; 226 patients in the development sample and 225 patients in the validation sample. Factor analysis, Cronbach's coefficient alpha, and correlation analysis were used to assess reliability and validity of the PDDC measure. RESULTS Three subscales were empirically determined by factor analysis: positive competence, negative dietary competence, and negative control. Cronbach's alphas for all subscales were good. Predicted relationships with measures of perceived health competence, self-efficacy, social support, and perceived dietary barriers were largely supported in construct validation. CONCLUSIONS This study provides initial support for the internal reliability and validity of a perceived diabetes and dietary competence measure. Further research is needed to determine its validity in other samples of African Americans with type 2 diabetes and its clinical utility in evaluating diabetes self-management training.
