Background: The CCAENA questionnaire was developed to assess care continuity across levels from the patients' perspective. The aim is to provide additional evidence on the psychometric properties of the scales of this questionnaire.
Methods: Cross-sectional study by means of a survey of a random sample of 1500 patients attended in primary and secondary care in three health care areas of the Catalan health care system. Data were collected in 2010 using the CCAENA questionnaire. To assess psychometric properties, an exploratory factor analysis was performed (construct validity) and the item-rest correlations and Cronbach's alpha were calculated (internal consistency). Spearman correlation coefficients were calculated (multidimensionality) and the ability to discriminate between groups was tested.
Results: The factor analysis resulted in 21 items grouped into three factors: patient-primary care provider relationship, patientsecondary care provider relationship and continuity across care levels. Cronbach's alpha indicated good internal consistency (0.97, 0.93, 0.80) and the correlation coefficients indicated that dimensions can be interpreted as separated scales. Scales discriminated patients according to health care area, age and educational level.
Conclusion: The CCAENA questionnaire has proved to be a valid and reliable tool for measuring patients' perceptions of continuity. Providers and researchers could apply the questionnaire to identify areas for health care improvement.
