Objective The aim of this study is twofold. First, it aims to determine the factor structure of the Mini‐Mental Adjustment to Cancer (Mini‐MAC) Scale by using confirmatory factor analysis (CFA) to compare the three‐factor, four‐factor, and five‐factor structures among 340 Taiwanese breast cancer patients. Second, it aims to test the difference in the correlations of coping strategies and the outcome measures between two populations: one‐month newly diagnosed and five‐year long‐term survival patients. Methods Two samples, composed of 142 newly diagnosed and 198 long‐term survival breast cancer patients, were recruited. Cancer‐specific coping and distress were assessed via the Mini‐MAC Scale and the Hospital Anxiety and Depression Scale (HADS), respectively. Results The CFA confirmed Watson's original five‐factor structure fit the data best. The correlation difference between the two samples lies in the fighting spirit (FS), which correlated negatively with distress among the newly diagnosed sample but had no correlation among the long‐term survivors. Moreover, fatalism (FA) was found to correlate positively with distress. Conclusions The five‐factor structure represents a more psychometrically sound measure of psychological adjustment in the current data set. The findings also support the argument that the relationships between coping and distress vary, to some degree, at different phases in the cancer trajectory. FS is only a positive predictor of psychological adjustment among newly diagnosed patients. Because of the exclusion of two items, FA showed a positive correlation with distress, a result that contradicts previous findings. Further theoretical and practical implications for FS and FA are discussed.Copyright © 2012 John Wiley & Sons, Ltd.
