Does the short form of the Problem Areas in Diabetes scale (K-PAID-5) have better psychometric properties than the full form (K-PAID) in Korean patients with type 2 diabetes?
The 5-item short form of the Problem Areas in Diabetes scale (K-PAID-5) demonstrates excellent psychometric properties and is preferable to the full form for measuring diabetes-related emotional distress in Korean patients.
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.
Lee et al. (Tue,) conducted a cross-sectional in Type 2 diabetes (n=440). K-PAID-5 (short form) vs. K-PAID (full form) was evaluated on Psychometric properties (factorial-construct validity and internal-consistency reliability). The 5-item short form of the Problem Areas in Diabetes scale (K-PAID-5) demonstrated excellent psychometric properties as a one-factor scale with a Cronbach's alpha of 0.87, proving preferable to the full form.
