EFFECTS OF MUSCULAR RELAXATION ON THE CHANGES OF Y-G TEST SCORES IN UNDERGRADUATES
Konno, Y. and Yoshikawa, N., Bunkyo University, Japan
Muscular relaxation could enhance positive affective/cognitive attitudes toward oneself, others, and the external world. These attitudes may contribute to the change of personality traits measured by Y-G test. Thirty- six undergraduates participated in this study. They were assigned to either Experimental group receiving the relaxation or Control group. "Therapeutic- Touch," one of the muscular relaxation methods, was administered to the shoulders, the head, the neck, the back, and the foot. About two weeks before the relaxation, Experimental group was administered pre-Y-G test, and immediately after the relaxation they answered post-Y-G test. During the same interval, Control group was administered Y-G test twice. Y-G test comprises twelve scales: Depression, Cyclic Tendency, Inferiority Feelings, Nervousness, Lack of Objectivity, Lack of Cooperativeness, Lack of Agreeableness, General Activity, Rathymia, Thinking Extraversion, Ascendance, Social Extraversion. The post-Y-G test scores decreased for Depression, Inferiority Feeling, Nervousness, and Lack of Cooperativeness in Experimental group, while no distinctive changes were found between pre and post-Y-G scores in Control group. The participants of Experimental group were assigned to either High-D group or Low-D group according to pre- Y-G Depression score, then compared with post-Y-G Depression score between High-D and Low-D groups. High-D group showed significantly greater decrease in the post-test score than Low-D group. These results confirm the beneficial effect of muscular relaxation on reducing depressive tendency as indicated in the previous study (Konno and Yoshikawa, 2000).
