Psychosocial adjustment and mental health two months after coronary artery bypass surgery: a multisystemic analysis of patients' resources.

Resources related to cardiac patients' sense of self, marital quality, and social support were assessed before their first planned bypass surgery to determine their relationship with later psychosocial functioning. Six female and 45 male cardiac patients, 45-70 years old, answered self-report instruments 1 week before and 8-10 weeks after the operation. Regression analyses indicated that only the marital relationship variables made independent contributions to the prediction of functioning. Since self-report measures of resources can be affected by negative affectivity, a second level of analysis predicted change scores while controlling for initial levels of functioning. Marital flexibility and support were found to make an independent contribution to recovery. These results highlight the importance of marital resources in coping with the acute phase following bypass surgery and have implications for prevention and clinical practice.
