Social Comparison and Affiliation Under Threat: Effects on Recovery From Major Surgery

This study extends stress and affiliation research by examining the effects of preoperative roommate assignments on the affiliation patterns, preoperative anxiety, and postoperative recovery of 84 male coronary-bypass patients. Patients were assigned preoperatively to a room alone or to a semiprivate room with a roommate who was either cardiac or noncardiac and either preoperative or postoperative. Patients assigned to a roommate who was postoperative rather than preoperative were less anxious, were more ambulatory postoperatively, and had shorter postoperative stays. Independently, patients were more ambulatory postoperatively and were discharged sooner if assigned to a roommate who was cardiac rather than noncardiac. No-roommate patients generally had the slowest recoveries. Affiliations reflecting cognitive clarity concerns, emotional comparison, and emotional support were examined. Theoretical implications for research involving social comparison and affiliation under threat are considered.
