Determining the Relationship Between Intolerance of Uncertainty and Attitudes Toward Complementary and Alternative Medicine in Patients With Cancer.

Disease-related uncertainty and the factors associated with uncertainty in patients with cancer have not been adequately investigated. This study aimed to determine the relationship between intolerance of uncertainty and attitudes toward complementary and alternative medicine (CAM) in patients with cancer. This cross-sectional descriptive study included 351 patients treated in the oncology clinic of a university hospital. All participants completed the Holistic Complementary and Alternative Medicine Questionnaire (HCAMQ) and the 12-item Intolerance of Uncertainty Scale (IUS-12). Most patients (84.3%) said that they had information about CAM, 39.7% reported obtaining this information from their social environment, 83.2% said that they believed that CAM methods are effective, and 76.0% reported not telling health care professionals about their CAM use. Mean IUS-12 and HCAMQ total scores were 46.53 ± 2.05 and 32.11 ± 2.32, respectively, and showed a weak negative correlation. The patients in our study showed high intolerance of uncertainty and a moderately positive attitude toward CAM, and most patients did not notify health care professionals of their CAM use. Therefore, we recommend assessing intolerance of uncertainty and CAM use in this patient group. By identifying patients experiencing uncertainty and seeking different treatment, nurses can support patients physiologically, psychologically, and socially, and can explain the effects of CAM use.
