Does the COPD assessment test (CAT(TM)) questionnaire produce similar results when self- or interviewer administered?
The COPD assessment test (CAT) is a questionnaire that assesses the impact of chronic obstructive pulmonary disease (COPD) on health status, but some patients have difficulties filling it up by themselves. We examined whether the mode of administration of the Spanish version of CAT (self vs. interviewer) influences its scores and/or psychometric properties. ⋯ The mode of administration does not influence CAT scores or its psychometric properties. Hence, both modes of administration can be used in clinical practice depending on the physician judgment of patient's capacity.
