Body image mediates the effect of stoma status on psychological distress and quality of life in patients with colorectal cancer

Objective We investigated the effect of stoma status (permanent stoma, temporary stoma, or non-stoma) on psychological distress and quality of life (QOL) in Chinese patients with colorectal cancer (CRC) in the early postoperative stage. We also investigated whether body image mediated the association between stoma status and psychological distress and QOL. Methods A convenience sample of 282 CRC patients 1 to 2 weeks postsurgery participated in an observational, cross-sectional study. Participants completed the following self-report measures: Body Image Scale, Distress Thermometer, Hospital Anxiety and Depression Scale, and Core Quality of Life Questionnaire. Results The temporary stoma group (TS) and the permanent stoma group (PS) reported worse body image and higher levels of anxiety and depression than the non-stoma group (P < .05). PS reported worse body image than TS (P < .01). Depression and significant body image problems were more prevalent in PS than in TS (P < .05). Stoma status was the strongest factor associated with body image, distress, and depression (P < .05). CRC patients who were younger or in later clinical stages had poorer body image. Body image fully mediated the effect of stoma status on anxiety, depression, and global QOL in PS and TS, but mediated the effect on distress only in PS. Conclusions Body image problems are common in stoma patients in the early postoperative stage and require early assessment. This study helps to elucidate the role of body image as a mediator. Longitudinal studies are needed to further explore body image distress trajectories.
