Abstract :
BACKGROUND: Coronary artery bypass graft (CABG) surgery is the most effective treatment for
cardiovascular disease (CVD). Adherence to treatment after CABG surgery is very important. One of
the educational models used in this regard is the BASNEF (Belief, Attitudes, Subjective Norms, and
Enabling Factors) model. The present study aimed to assess the effect of an educational intervention
based on BASNEF model on adherence to treatment in patients after CABG surgery.
METHODS: The present study was a randomized clinical trial. In this study, 72 patients who had
undergone CABG surgery participated in the two intervention and control groups. Patients in
the intervention group took part in 4 40-minute educational sessions based on BASNEF model
after discharge. The patients in both groups completed the Modanloo Adherence to Treatment
Questionnaire (MATQ) and a researcher-made BASNEF model questionnaire before the
intervention, after the educational intervention, and at the 3-month follow-up. Data were
analyzed using independent t-test, chi-square test, Man-Whitney test, and repeated measures
analysis of variance (ANOVA). Mauchly’s sphericity test was used for testing sphericity and the
Greenhouse-Geisser correction was used in the case of lack of sphericity. All P-values of less
than 0.05 were considered significant.
RESULTS: The total score of the MATQ and its subscales had significantly improved in the
intervention group after the intervention compared with the control group (P < 0.050). In
addition, the mean scores of the model constructs (knowledge, attitude, behavior intention,
subjective norms, and enabling factors) had significantly improved after the intervention in the
intervention group in comparison with the control group (P < 0.050).
CONCLUSION: The educational intervention based on BASNEF model improved adherence to
treatment in patients after CABG surgery. Moreover, the model constructs improved in the
intervention group in comparison with the control group after the intervention.
