In this introduction to psychotherapy Sidney Bloch cuts through the jargon and mystique to make the subject approachable for both general reader and student. He covers both theory and practice, discussing the kind of people and problems that can be helped by treatment, the qualities needed in a therapist, and the ethical difficulties he has to face. He examines the psychodynamic, humanist-existential, and behavioural theoretical approaches, and outlines the findings of systematic research to dispel the myth that there are no `facts' in psychotherapy. Three commonly used group therapies are described - long-term small group therapy, family therapy, and marital therapy. The encounter group and the self-help group, both of social significance today, have also been included.
