There is so much of value in this book that a reviewer can give only brief examples. Consider, for example, the value of distinguishing among signs, symptoms, and traits (pp. 119–121), differences between the MMPI and the Millon Clinical Multiaxial Inventory I and II on item redundancy and scale overlap (pp. 256–257), or ways in which dependent, independent, ambivalent, and detached styles occur with regard to the activity-passivity dimension, yielding 11 coping strategies (pp. 65–67). The author has interesting insights about depression in such areas as borderline personality, narcissistic personality, antisocial personality, and other categories; the big-five-factor model (extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience); and various kinds of tests, including his own but also the Thematic Apperception Test, the Children's Apperception Test, the Make-A-Picture Story, and many others.
