The psychometric properties of a Chinese version of the Mini-Mental Adjustment to Cancer scale (Mini-MAC) were examined among 115 Chinese cancer patients in Hong Kong. The five subscales from the original Mini-MAC (Anxious Preoccupation, Helpless–Hopeless, Fighting Spirit, Fatalism, Cognitive Avoidance) had acceptable internal reliabilities (Cronbach's α ranged from 0.65 to 0.88) and construct validities in our sample. Factor analysis suggested three factors: (1) Negative Emotion (α=0.91) contained items of the Anxious Preoccupation and the Helpless–Hopeless subscales of the original Mini-MAC, (2) Positive Attitude (α=0.77) combined the Fighting Spirit and the Fatalism subscales of the original version, and (3) Cognitive Avoidance (α=0.65) which was identical to the Cognitive Avoidance subscale of the original Mini-MAC. Construct validities of the novel factors were shown by their correlations with HADS Anxiety and Depression scores in the predicted directions. It was concluded that both the 5-factor model from the original Mini-MAC and the 3-factor model from the present study were valid in Hong Kong Chinese cancer patients. The results were discussed in terms of the meaning of the original Mini-MAC factors and cultural differences in coping functions between Chinese and UK cancer patients.
