Abstract:
The purposes of this predictive correlational research were to study the quality of life in colorectal cancer adult patients with colostomies, to examine their relationships of knowledge, self-esteem, self-care, social support and quality of life, and to examine the factors predicting their quality of life. The sample comprised 110 colorectal cancer adult patients with colostomies recruited from the outpatient department of a super tertiary care hospital in Bangkok by a multi-stage sampling strategy. The research instruments comprised patients demographic data and colorectal cancer data and treatment record forms, the quality of life index, knowledge assessment scale, self-esteem assessment scale, self-care assessment scale and social support assessment scale of colorectal cancer adult patients with colostomys. The reliabilities were 0.92, 0.78, 0.88, 0.95 and 0.84 respectively. Descriptive quantitative statistics, Pearsons correlation, and stepwise multiple regression were used in statistical analyses. The major findings were as follows 1. Colorectal cancer adult patients with colostomies had a high level of quality of life. (Mean= 67.1, SD=14.56) 2. Self-esteem and self-care were significantly positively related to quality of life at the high level (r= 0.772 and 0.737 respectively). Knowledge and social support were significantly positively related to quality of life at a low level (r= 0.489 and 0.460 respectively). 3. Knowledge, self-esteem and self-care were predictors with73.70% of total variance explained for quality of life in colorectal cancer adult patients.(R²=0.737)
