Aj. Christensen et al., PERCEIVED HEALTH COMPETENCE, HEALTH LOCUS OF CONTROL, AND PATIENT ADHERENCE IN RENAL DIALYSIS, Cognitive therapy and research, 20(4), 1996, pp. 411-421
An emerging view in the literature regarding health locus of control (
NLC) and health behavior suggests that HLC beliefs might affect behavi
or only through the interaction of HLC with other health-related expec
tancies. We examined internal and powerful others HLC beliefs as moder
ators of the relationship between a recently developed measure of ''pe
rceived health competence'' and medical regimen adherence in 81 renal
dialysis patients. The hypothesized interaction was significant, sugge
sting a moderating role for HLC. The pattern of the interaction differ
ed from prediction. Greater perceived health competence was associated
with more favorable adherence only for those patients scoring low on
internal and high on powerful others HLC, This pattern suggests that a
high degree of perceived competence is advantageous for those patient
s with predominant confidence in the actions of their health-care prov
iders.
