Abstract
Background: Little research has examined the moderating influence of posttraumatic growth (PTG) on the relationship between social support and quality of life.
Objectives: This study examined the relationship between social support and quality of life by the level of PTG in colorectal cancer patients with ostomies.
Methods: Using a cross-sectional design, colorectal cancer patients with ostomies (n = 140) were recruited using convenience sampling. The City of Hope Quality of Life-Ostomy, the Multidimensional Scale of Social Support, and the Posttraumatic Growth Inventory measured quality of life, social support, and PTG, respectively.
Results: Social support and PTG were positively related to psychological and social well-being. Higher social support was associated with better psychological and social well-being. Posttraumatic growth moderated the relationship between psychological and social well-being. At a low and moderate level of PTG, social support was more strongly associated with psychological and social well-being, whereas at high levels, this association was not significant.
Conclusions: Findings highlight the significance of social support to improve the quality of life for colorectal cancer patients with an ostomy, particularly those with low levels of PTG.
Implications for Practice: Screening for patients' positive cognitive adaptations while living with an ostomy could identify those who might need further social support to improve their quality of life. Further, intensive social support programs might promote the quality of life for colorectal patients with an ostomy, which was found to be effective for those with low levels of PTG.
