This article tests a model of self-regulatory development in which families
' cognitive beliefs and behavioral skills for managing asthma symptoms emer
ge in four successive phases: asthma symptom avoidance, asthma acceptance,
asthma compliance, and asthma self-regulation, Confirmatory factor analyses
revealed that the hypothesized multiphase model provided the best factoria
l fit for phase items. Subsequent Guttman analyses of the families' phase s
cores revealed a high degree of sequential ordering. Finally, trend analyse
s of family phase differences revealed a significant negative linear relati
on with measures of asthma severity and a significant positive linear relat
ion with physician care and concern measures, asthma regulatory measures, a
nd beliefs in Western biomedical practices. Despite receiving primary care
for asthma at a major metropolitan university hospital, 83% of me sample we
re classified as precompliant. The phase model of asthma self-regulatory de
velopment offers a qualitative approach for investigating the psychological
determinants of asthma self-regulatory behavior.
