A comprehensive assessment of satisfaction with care: preliminary psychometric analysis in French, Polish, Swedish and Italian oncology patients.

Satisfaction with care may be closely related to quality of life in cancer patients. This evaluation is especially relevant when quality of care is considered. The present study assessed whether equivalent scaling properties could be found in a comprehensive assessment of satisfaction with care (CASC) administered in cancer patients from French, Polish and Swedish oncology settings, in comparison to the scaling properties previously evidenced in the CASC with an Italian sample. A total of 140, 186 and 133 oncology patients were approached in France, Poland and Sweden, respectively. Specific items in the CASC were identified as consistently omitted across country samples. Multitrait scaling analysis on an item-grouping adapted for the French, Polish, Swedish and Italian samples provided excellent internal consistencies and convergent validity estimates. Discriminant validity proved less satisfactory, evidencing overlap between hypothesised care dimensions across country samples. The identification of omitted or overlapping items will lead to the design of a revised CASC version to further test in larger cross-cultural samples.
