Randomized Controlled Trial Clinical Trial
How does a change in the administration method affect the reliability of the COOP/WONCA Charts? World Organization of National Colleges, Academies and Academic Associations of General Practitioners/Family Physicians.
An interviewer is often needed to administer the COOP/WONCA Charts to Chinese patients, and this may affect the reliability of results. ⋯ The Chinese COOP/WONCA Charts were reliable in detecting real differences when administered by an interviewer. A change in the method of administration significantly decreased the reliability of the results. The use of more than one method of data collection in the same survey should be discouraged.
