ObjectiveTo analyze the impact of social resources on self-management in patients undergoing coronary stent implantation, and provide evidence for nurses to predict patients' self-management behavior and take intervening measures. MethodsA convenience sample of 359 patients undergoing coronary stent implantation between July and December 2013 was selected according to the criteria. Three instruments were used to collect data including general data scale, chronic illness resources survey (CIRS) and coronary artery disease self-management scale (CSMS). ResultsThe score of CIRS among 359 patients was 2.77±0.60, and the scores of six subscales in descending order were support of neighborhood/community, media and policy, and family and friends, and personal coping, and support of physician/health care team, and organizations. The total score of CSMS was 55.58±10.59, and the scores of three subscales in descending order were:daily management, emotion management, and medical management. The total self-management score and factor scores of CIRS were significantly correlated with the total and factor scores of CSMS (r=0.183-0.663, P<0.05), while the correlation of support of physician/health care team and family and friends with daily life management was negative (r=-0.215, -0.294; P<0.05). ConclusionIn this study, patients' total social resources are at a low level; the standard of self-management is at a moderate level, while medical management has the lowest score; good social resources can promote self-management, but supports from medical staff, family and friends are bad for patients' daily life management.
