Relationships among economic stress, social support, age and quality of life in patients with chronic wounds: A moderated mediation model

Abstract Aims The aims of this study were as follows: (a) to determine if social support mediates the relationship between economic stress and quality of life; and (b) to explore whether participants’ ages would moderate the indirect relationship between economic stress and quality of life through social support. Design A questionnaire‐based, cross‐sectional study. Methods From January 2015–June 2016, a total of 300 patients with chronic wounds were recruited from three hospitals. Data regarding economic stress, social support and quality of life were collected through survey questionnaires. The moderated mediation analysis was examined using the Hayes’ PROCESS macro modelling tool, based on the bias‐corrected bootstrapping method. Results Economic stress was negatively correlated with quality of life and social support. The indirect effect of economic stress on quality of life through social support was negative. Furthermore, age moderated the relationship between economic stress and quality of life, as well as the relationship between economic stress and social support. Conclusion Reducing economic stress and improving social support are important strategies for improving quality of life in patients with chronic wounds, especially for younger patients. Impact Patients with chronic wounds experience considerable economic stress and severely impaired quality of life; however, little is known about the inner mechanisms of this relationship. This study emphasized the importance of providing social support in coping with the damage that economic stress causes to health. Clinical nurses should strengthen the comprehensive assessment of the socioeconomic status of patients and adjust nursing plans timely, to reduce the economic burden of patients based on the rational use of wound care materials. Moreover, when nursing for patients with chronic wounds, especially the elders, caregivers should strengthen the evaluation of social support and develop interventions to improve social support.
