This study examined the role of psychological distress—anxiety and depression—in
adherence and prognosis among patients subjected to Coronary Artery Bypass Grafting
(CABG). By using an interrupted time-series design with one group, 100 patients
were observed. They responded to the Hospital Anxiety and Depression Scale before
surgery, at the first review (a week after hospital discharge), and at the second review (a
month after first review). Participants also completed the Adherence Scale for Cardiac
Patients, and the Biopsychosocial Prognosis Scale for CABG at the second review.
Hierarchical multiple linear regression analyses revealed that anxiety and depression
at three time-points before and after surgery together predicted participants’ outcomes
by significantly explaining up to 21% of variance in adherence and 52% of variance
in prognosis. However, simple linear regression analysis showed that adherence
significantly explained only 5% of variance in prognosis. Psychological distress, thus,
affects how effectively patients follow the post-operative care regimen and how well
they recover after CABG.
