Objective: The purpose of this study
is to determine whether patient activation is a changing or
changeable characteristic and to assess whether changes in
activation also are accompanied by changes in health behavior.
Study Methods: To obtain variability
in activation and self-management behavior, a controlled trial
with chronic disease patients randomized into either intervention
or control conditions was employed. In addition, changes in
activation that occurred in the total sample were also examined
for the study period. Using Mplus growth models, activation
latent growth classes were identified and used in the analysis
to predict changes in health behaviors and health outcomes.
Data Sources: Survey data from the 479
participants were collected at baseline, 6 weeks, and 6 months.
Principal Findings: Positive change in
activation is related to positive change in a variety of self-management
behaviors. This is true even when the behavior in question
is not being performed at baseline. When the behavior is already
being performed at baseline, an increase in activation is
related to maintaining a relatively high level of the behavior
over time. The impact of the intervention, however, was less
clear, as the increase in activation in the intervention group
was matched by nearly equal increases in the control group.
Conclusions: Results suggest that if
activation is increased, a variety of improved behaviors will
follow. The question still remains, however, as to what interventions
will improve activation.
