Interrelationships among quality of life variables in cancer patients

Purpose. This dissertation aimed to delineate a relationship between variables frequently discussed in the cancer literature and overall quality of life, in order to promote a greater understanding of how to intervene in the treatment process in meaningful ways to positively impact quality of life.;Method. These relationships were examined in a sample of 44 lung (n = 29) and colorectal (n = 15) cancer patients (22 male and 22 female, mean age 65.5 years). Variables included: (a) gender role orientation, (b) locus of control, (c) collective coping behaviors, (d) psychological distress, and (e) quality of life. Data on these variables was collected using the survey method. Statistical analyses included t-tests, Pearson r and multiple regression analyses.;Findings. Overall, there were no significant gender differences among the variables. There were also no significant differences among types of cancer. However, lower psychological distress significantly predicted higher quality of life (beta = .84, p < .001). Additionally, high chance locus of control scores, meaning patients who believe whether they are sick or well depends on luck or fate, significantly predicted lower quality of life (beta = -.34, p < .001). Results suggest that addressing psychological distress and health locus of control in the treatment of cancer may enhance quality of life.
