Adaptation and psychometric properties of the PACIC short form

Objectives: The Patient Assessment of Chronic Illness Care (PACIC) is a widely used instrument to evaluate the quality and patientcenteredness of chronic illness care based on the Chronic Care Model (CCM). It is a validated and reliable instrument which consists of 20 items. Additionally, a short form with 11 items was developed. The aim of this study was to translate this short form into German and examine the psychometric properties among patients with a chronic illness in Germany. Study Design: Observational study design. Methods: We performed a translation and cultural adaptation of the PACIC short form into German. The German version was externally validated with the 20-item PACIC. Cronbach a, descriptive statistics, and principal component analysis were used to assess psychometric properties. Results: In total, 264 primary care patients completed the PACIC short form. The PACIC short form showed good convergent construct validity to the 20-item PACIC (Spearman rank correlation 0.82, P <.001) and high internal consistency (Cronbach a 0.87). Principal component analysis underlined the 1-dimensional structure of the instrument. No correlation between the mean overall score of the PACIC short form and the number of chronic conditions (r = 0.068; P = .273) was found. Conclusions: The PACIC short form showed good to very good psychometric properties and reliable measures regarding patient assessment of receiving care congruent with the CCM. It is a less burdensome instrument which can be used for further research of patients with more than 1 chronic condition.
