A previously developed model of disease disability, functional limitat
ion, and perceived health was examined for race and/or gender biases.
This model focuses on (a) the direct effects of three factors on perce
ived health status, (b) how disability, functional limitations, and se
lf-rated health interrelate, and (c) how race and gender condition the
se interrelationships. The results confirm the construct validity of s
eparate dimensions of disability and functional limitation, and indica
te that their differential effects are further modified by gender. Eig
ht significant differences in structural effects are identified, inclu
ding one gender effect among both blacks and whites, and seven additio
nal gender effects among whites. In the structural model, then, most d
ifferences are gender differences among whites. The significant racial
differences within gender were found only in the measurement model. R
ace differences for upper body disability and perceived health are con
sistent across gender. Sex differences, however, in measures of basic
ADLs and household ADLs are not consistent across race. The findings c
onfirm earlier conclusions that differences in the measurement of heal
th exist between males and females, and between blacks and whites, but
that the differences in the causes of perceived health exist only bet
ween males and females.
