Construct validity was tested by correlating each of
the dimensional variables with self-efficacy unadjusted
and then adjusted for covariates. The first step in testing
relationships was to describe the bivariate correlations
between self-efficacy and the identified measures representing each domain. Table 4 shows that self-efficacy was
highly correlated with all of the domains of QOL before
and after adjusting for covariates and in the anticipated
directions. Overall QOL, as measured by the IWB, was regressed
on demographics, self-efficacy, and specific QOL
dimensions to confirm the relationship of self-efficacy
with overall QOL
