Popis: | Objectives: A psychometric scale for assessing cancer-related worry among cancer patients, called the Brief Cancer-Related Worry Inventory (BCWI), was developed. Methods: A cross-sectional questionnaire survey for item development was conducted of 112 Japanese patients diagnosed with breast cancer, and test–retest validation analysis was conducted using the data from another prospective study of 20 lung cancer patients. The questionnaire contained 15 newly developed items for cancer-related worry, the Hospital Anxiety and Depression Scale, The Impact of Event Scale Revised, and the Medical Outcomes Study Short Form-8. Results: Exploratory factor analysis of the 15 items yielded a 3-factor structure including (1) future prospects, (2) physical and symptomatic problems and (3) social and interpersonal problems. A second-order confirmatory factor analysis identified a second-order factor called cancer-related worry and confirmed the factor structure with an acceptable fit (chi-square (df=87)=160.16, P=0.001; GFI=0.83; CFI=0.92; RMSEA=0.09). The internal consistency and test–retest reliability were confirmed with the lung cancer sample. Multidimensional scaling found that cancer-related worry is separate from anxiety, depression, and posttraumatic stress disorder (PTSD) symptoms. Conclusion: Our study succeeded in developing and confirming the validity and reliability of a BCWI. The study also confirmed the discriminable aspects of cancer-related worry from anxiety, depression, and PTSD symptoms. Copyright © 2008 John Wiley & Sons, Ltd. |
