Progress in Behavior Modification, Volume 11 covers the developments in the study of behavior modification. The book discusses the pluralistic psychology of behavior change; the methodological issues in child behavior therapy; and the interpersonal-skills training with adolescents. The text also describes the behavior modification of work and work-related problems; the behavioral treatment of migraine and muscle-contraction headaches; and the modification of children’s social withdrawal. An assessment of hyperactive children, with regard to the psychometric, methodological, and practical considerations, is considered. Psychologists, psychiatrists, and sociologists will find the book invaluable.
