The Dartmouth Primary Care Cooperative Information Project (COOP) char
ts and mini-Duke-UNC Health Profile (DUHP) instruments were developed
to screen patients' health status in clinical settings. The purpose of
this study is to determine patient preferences for use of these instr
uments in a family practice setting. A sample of 203 consecutive, cons
enting patients presenting to a university-based family practice clini
c was administered both instruments. Patients then completed a questio
nnaire which asked which instrument was preferred and why. Overall, ne
ither instrument was significantly preferred by patients. Patient perc
eived accuracy for the COOP was significantly positively related to ag
e and negatively related to quality of life. Patient ease, rather than
perceived accuracy, dominated the preference relationship, yet neithe
r instrument was found to be easier to use by the elderly or those in
poorer health. This study reveals that patients prefer instruments whi
ch are easier to use, but that neither the COOP nor the mini-DUHP was
found to be significantly easier to use by all patients. However, the
COOP was perceived to be more accurate for a subset of patients, the e
lderly with poor quality of life beyond the realm of health.
