Objective: To evaluate the level of chronic care patients must be involved. The Danish version of the 20-item Patient Assessment of Care for Chronic Conditions PACIC questionnaire consisting of 5 scales and an overall summary score measuring patient reported assessment of structured chronic care has not been evaluated with regard to psychometric properties. This study aims to assess data quality and internal consistency and to validate the proposed factorial structure. Materials and methods: Setting: Diabetes population receiving chronic care in Denmark. Subjects: A total of 624 patients aged 18 or more with type1 or type2 diabetes sampled in a national register of people with diabetes. They were sent a Danish version of the PACIC. Main outcome measures: Data quality (mean, median, item response, missing, floor and ceiling effects), internal consistency (Cronbach's alpha and average interitem correlation), item-rest correlations. Model fit from confirmatory factor analysis (CFA). Results: We present the psychometric properties of the questionnaire and the first results evaluating chronic care in Danish people with diabetes. Conclusions: The complexity of validation is greater when the same questionnaire is constructed and applied to different countries with diverse cultural backgrounds and health care systems. It is decisive, that translated questionnaires are validated in country they are used.
