The promo material states that "The Tools transcends the typical self-help genre because of its paradigm-changing material, the credibility of its authors, and the instant appeal and empowerment of its message."
Perhaps... this book is better than much of the self-help genre but hardly paradigm-changing to anybody who knows the field of psychotherapy and psychopathology. Rather, this book outlines principles of change one would expect from a self-help book based on treating celebs -- principally based on quick fixes and psychobabble that is aimed at pleasing your customers, i.e., "patients".
While this material has its place, it hardly scratches the surface in many respects. I suggest that individual seeking self-help consider the more useful, if more challenging, books like David Burns tried and true CBT book for depression, "Feeling Good: The New Mood Therapy" or more recent more empirically based books such as Aaron Beck and Clarks book "The Anxiety and Worry Workbook".
Finally, for individuals with serious psychological difficulties, I suggest they consult a reputable (trust your instincts too) psychotherapist -- somebody licensed.
