THIS STUDY ATTEMPTED TO FIND OUT WHETHER (1) THE METHODS FOR ATTAINING NEUROMUSCULAR RELAXATION THAT HAVE PROVED FRUITFUL IN THE ONE-TO-ONE RELATIONSHIP OF THE CLINIC CAN BE SUCCESSFULLY ADAPTED TO THE TEACHER-CLASS RELATIONSHIP OF THE CLASSROOM AND GYMNASIUM, AND (2) NEUROMUSCULAR RELAXATION CAN BE TAUGHT SUCCESSFULLY BY AN APPROPRIATELY TRAINED PERSON WHO POSSESSES NO SPECIAL PERSONALITY TRAITS AND IS WITHOUT THE BENEFIT OF THE PHYSICIAN'S "STATUS HALO." BASED ON THE PROGRESSIVE RELAXATION METHOD OF E. JACOBSON, A 15-LESSON OUTLINE WAS DESIGNED FOR CLASSROOM INSTRUCTION USING TECHNIQUES TO REDUCE THE ACTIVITY OF THE NERVOUS AND MUSCULAR SYSTEMS. IN ADDITION, A TEACHER-TRAINING COURSE WAS DESIGNED ON THE THEORY, PRACTICE, AND TEACHING OF NEUROMUSCULAR RELAXATION. PERSONS WHO SUCCESSFULLY COMPLETED THE LATTER COURSE INSTRUCTED EXPERIMENTAL CLASSES OF COLLEGE STUDENTS AND OTHER GROUPS COMPOSED OF SUBJECTS WHO LEARNED RELAXATION THROUGH COURSES OFFERED IN LOCAL CHURCHES OR AT THE YMCA. ALL EXPERIMENTAL AND CONTROL SUBJECTS WERE GIVEN A BATTERY OF TESTS. RESULTS SHOWED THAT MOST ADULTS CAN BE TAUGHT THE SKILL OF RELAXATION IN 15 INSTRUCTION SESSIONS DURING A PERIOD OF 8 WEEKS. (JM)
