Reliability and Validity of a Twelve-Minute Walking Test for Coronary Heart Disease Patients

Abstract

This study examined the reliability and validity of a 12-min. walking test for coronary heart disease patients. CHD patients (28 men, 18 women) were recruited out of 86 CHD patients of the Martini Hospital Groningen, The Netherlands. 46 CHD patients (age M = 66.0 yr., SD = 6.8) participated in the reliability study and 24 (age M = 62.0 yr., SD = 9.2) in the validity study. A test-retest analysis showed a satisfactory Bland-Altman plot and an intraclass coefficient of .98. The Pearson correlation between the score on the test and the VO₂ peak was .77. This test gives a reliable and valid assessment of cardiorespiratory fitness of CHD patients.
