BACKGROUND
The Problem Areas in Diabetes (PAID) scale is widely used for measuring diabetes-related emotional distress. There has been debate over the last 2 decades about the underlying factorial-construct validity of the PAID, with one- to four-factor structures being reported. A short form of the PAID, which comprises five items (PAID-5), was recently developed using Western patients with type 2 diabetes. This study measured the psychometric properties of the full and short forms of the PAID in Korean patients with type 2 diabetes, with the aim of determining which form is preferable.
METHODS
The PAID and PAID-5 were translated into Korean (K-PAID and K-PAID-5, respectively) using a forward-and-backward translation technique. The study participants were recruited from university hospitals. The factorial-construct, convergent, and known-groups validity, and internal-consistency and test-retest reliability of both the K-PAID and K-PAID-5 were evaluated.
RESULTS
For the K-PAID, confirmatory factor analysis revealed a marginal fit to the one-, two-, three-, and four-factor models. The three- and four-factor models of the K-PAID partially satisfied the internal-consistency and test-retest reliability, and convergent and known-groups validity. For the K-PAID-5, confirmatory factor analysis demonstrated an excellent fit to the one-factor model, with a Cronbach's alpha of 0.87 and an intraclass correlation coefficient of 0.89. The K-PAID-5 satisfied the convergent validity, as evaluated using the Center for Epidemiologic Studies Depression Scale and hemoglobin A1c. Known-groups validity by gender was also satisfied.
CONCLUSIONS
The K-PAID-5 demonstrated excellent psychometric properties as a one-factor scale. The brevity of the K-PAID-5 represents a major advantage in a practical context in that it may impose a minimum burden upon patients with diabetes.
背景
糖尿病问题领域（PAID）量表被广泛用于测量糖尿病相关的情绪困扰。在过去20年里，关于PAID潜在的因子结构效度一直存在争议，有一到四因素结构的报道。最近，使用西方2型糖尿病患者开发了一种PAID的简短形式，包括五个项目（PAID-5）。本研究测量了韩国2型糖尿病患者中PAID完整形式和简短形式的心理测量特性，目的是确定哪种形式更可取。
方法
采用正向和反向翻译技术将PAID和PAID-5翻译成韩语（分别为K-PAID和K-PAID-5）。研究参与者从大学医院招募。评估了K-PAID和K-PAID-5的因子结构、收敛效度、已知群体效度以及内部一致性和重测信度。
结果
对于K-PAID，验证性因子分析显示其一因素、二因素、三因素和四因素模型拟合度一般。K-PAID的三因素和四因素模型部分满足内部一致性和重测信度以及收敛效度和已知群体效度。对于K-PAID-5，验证性因子分析表明其一因素模型拟合良好，克朗巴哈系数为0.87，组内相关系数为0.89。K-PAID-5满足收敛效度，这是通过流行病学研究中心抑郁量表和糖化血红蛋白评估得出的。按性别划分的已知群体效度也得到满足。
结论
K-PAID-5作为单因素量表表现出优异的心理测量特性。K-PAID-5的简短性在实际应用中是一个主要优势，因为它可能给糖尿病患者带来最小的负担。
