Progress in Behavior Modification, Volume 20 covers the developments in the study of behavior modification. The book discusses the guidelines for the use of contingent electric shock to treat aberrant behavior; the motor activity measurements and DSM-IIII; and the innovations in behavioral medicine. The text also describes the behavioral interventions as adjunctive treatments for chronic asthma; health behavior change at the worksite, with regard to cardiovascular risk reduction; and the role of behavioral change procedures in multifactorial coronary heart disease prevention programs. Psychologists, psychiatrists, and people involved in the study of behavior modification will find the book invaluable.
