An analysis of patients' values before and six months after coronary artery bypass graft surgery in relation to psychosocial adjustment to surgery
This study describes the impact of coronary artery bypass graft (CABG) surgery on the ranks of patients' personal values. The relationship between difference in value ranks and psychosocial adjustment to CABG surgery was also investigated. A one group pretest-posttest design was employed to identify the differences in pre-surgery value ranks and six month post-surgery value ranks.
One day before surgery and six months after discharge a consecutive sample of 67 hospitalized participants ranked two sets of 18 values using the Rokeach Value Survey. Six months after surgery, psychosocial adjustment was also measured using the Psychosocial Adjustment to Illness Scale (PAIS). A Pearson product moment correlation was calculated to test the hypothesis that a direct relationship exists between the difference in value ranks and positive psychosocial adjustment to CABG surgery.
Fifty-six of the 60 available participants completed and returned the six-month follow-up mail surveys. The median value ranks for the three most and least important values of each set were essentially the same for the ranks obtained before and after CABG surgery. The PAIS results obtained six months after surgery indicated that all but four of the 56 participants had a positive psychosocial adjustment to surgery. There was no significant relationship between PAIS and value difference scores (r =
