Purpose This study investigated differences in inner strength, multiple identities, and quality of life among colorectal cancer survivors, considering gender and the presence of an ostomy. It also focused on identifying factors that influenced their quality of life. Methods In this cross-sectional study, 170 colorectal cancer survivors were recruited.
Inner strength, multiple identities, and quality of life were assessed through an online survey. Within each subgroup, comparisons were made in two ways: (a) between women and men; and (b) between ostomy and non-ostomy groups. Results The quality of life for colorectal cancer survivors was higher among men than women. For inner strength, men reported higher levels of anguish and searching, whereas women showed higher levels of connectedness. The quality of life was higher in the non-ostomy group than the ostomy group. However, the non-ostomy group had a higher level of anguish and searching than the ostomy group. Inner strength emerged as the most powerful factor influencing quality of life after adjusting for age and gender. Conclusion This study emphasizes the significance of inner strength in colorectal cancer survivors. It provides a deeper understanding of quality of life in colorectal cancer survivors by examining factors that influence it and considering how these effects differ based on gender and the presence of an ostomy. To improve the quality of life of colorectal cancer survivors, it is essential to comprehend the roles of factors such as gender and ostomy and develop individualized interventions tailored to their specific characteristics.
