title: Adaptation and psychometric properties of the PACIC short form.
abstract: The Patient Assessment of Chronic Illness Care (PACIC) is a widely used instrument to evaluate the quality and patient-centeredness 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.
  
  
  
  Observational study design.
  
  
  
  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.
  
  
  
  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.
  
  
  
  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.
