After clinician and patient interviews, concepts were further refined into four domains and 17 concepts; test versions of the PACT-Q were then created simultaneously in three languages, each containing 27 items grouped into four domains: "Treatment Expectations" (7 items), "Convenience" (11 items), "Burden of Disease and Treatment" (2 items) and "Anticoagulant Treatment Satisfaction" (7 items).
The specific items may be summarized into three dimensions: symptoms/problems (12 items), effects of kidney disease on daily life (8 items), and burden of kidney disease (4 items) [ 20].
