ABSTRACT
The central question addressed in this book was: In the field of psychotherapy, what works for children, adolescents, and adults? To answer this question, a wide-ranging review of scientific evidence concerning the effectiveness of psychotherapy was conducted. The large rigorous body of evidence reviewed showed, unequivocally, that psychotherapy and psychological interventions are effective in helping children, adolescents, adults, people in later life, and people with intellectual and pervasive developmental disabilities with a wide range of psychological difficulties.
