Abstract
Using a modified version of the Hackett-Cassem denial scale we measured preoperative denial in 121 patients scheduled for CABG surgery. A significant inverse relationship was found between the denial scale and Hamilton Anxiety measures four days postoperatively ( p < .02). Longitudinal assessments were carried out using the Spielberger State Anxiety Inventory (SSAI), the Zung Self-Rating Depression Scale (Zung SDS) and the Psychosocial Adjustment to Illness Scale (PAIS). Six months following the surgery, significant negative relationships between denial and these self-report outcome measures were observed as follows: denial and SSAI ( p < .001), denial and Zung SDS ( p < .01), and denial and PAIS ( p < .01). However, the same analysis at twelve months showed no statistically significant correlations between denial and these psychologic outcome measures. Our findings suggest that denial serves as an adaptive mechanism, especially in the immediate postoperative period. Furthermore, higher levels of denial may be predictive of improved psychologic outcome for up to six months following surgery. Subsequently, however, other events, unrelated to the surgery, may be of greater importance than preoperative denial in determining psychological outcome from CABG surgery.Keywords
