The factorial validation of the Mini MAC - The Mental Adjustment to Cancer Scale, that measures mental adjustment to cancer, is investigated. After semantic validation, the scale was applied to a sample of 283 patients, average age 54 years old, suffering from cancer of different types and in various stages of the disease, and attended to at a university hospital. The factorability of the sample was appropriate (The Kaiser-Meyer-Olkin was 0.88); data were submitted to principal components analysis, oblique rotation, due to interdependence of factors. Seven factors attained eigenvalue greater than 1.0. Two factors showed good reliability ("Anxious Preoccupation" with Cronbach's Alpha = 0.87 and "Helpless/Hopeless" with Cronbach's Alpha = 0.74), with 13 items with loadings 0.40 or more, which explained 30% of total variance. Results suggested good psychometric quality. Difference between the factor structure of the original scale and that in current study explains the cultural and educational differences among samples.
