Effects of group music therapy on behavior
Total scores of NOSIE of the experimental group was significantly
higher than the control group (F ¼ 24.04, p < .001). The
experimental group reported consistently improved positive
behavior (social competence, social interest, & personal neatness)
and negative behavior (irritability, manifest psychosis, psychotic
depression) after completing 13 sessions of the group music therapy,
compared to that of the control group (Table 5).
