本研究以3338名成人糖尿病患者为研究对象，采用Rasch分析法，对糖尿病困扰量表和糖尿病问题领域量表的心理测量学效度进行了检验（1609人完成了糖尿病问题领域量表（n=675例1型糖尿病; n=934例2型糖尿病），1705人完成了糖尿病痛苦量表（n=693例1型糖尿病; n=1012例2型糖尿病））。虽然标准和收敛效度良好，Rasch分析显示次优精度和目标，项目不匹配。糖尿病痛苦量表中无法分辨的多维性表明应避免总分，而次优精度表明应谨慎使用医生相关和人际关系痛苦分量表。
This study used Rasch analysis to examine the psychometric validity of the Diabetes Distress Scale and the Problem Areas in Diabetes scale to assess diabetes distress in 3338 adults with diabetes (1609 completed the Problem Areas in Diabetes scale (n=675 type 1 diabetes; n=934 type 2 diabetes) and 1705 completed the Diabetes Distress Scale (n=693 type 1 diabetes; n=1012 type 2 diabetes)). While criterion and convergent validity were good, Rasch analysis revealed suboptimal precision and targeting, and item misfit. Unresolvable multidimensionality within the Diabetes Distress Scale suggests a total score should be avoided, while suboptimal precision suggests that the Physician-related and Interpersonal distress subscales should be used cautiously.
