ABSTRACT: To benefit from a Coronary Artery Bypass Graft
Surgery (CABG), patients must adhere to their therapeutic regimen. To test the
extent of which the Information-Motivation-Behavioral Skills (IMB) model constructs
explain the variability in adherence behaviors in CABG patients, and also to
examine the relationship between the IMB model constructs, CABG patients (N = 152)
were randomly assigned to either an intervention group, or a standard care
control group. They completed pretest measures, and were reassessed later.
Although perfect replication of the IMB model’s predicted pathways was not
achieved in this study, support for several of these pathways was demonstrated.
The estimated model for adherence-demonstrated good fit of the data. Motivation
was a significant predictor of adherence behavior in CABG patients. These
findings suggest that IMB model-based intervention that improves motivation can
enhance adherence. Therefore, CABG patients’ education programs should mainly
target motivation in order to affect adherence behavior.
