Comparison of the effectiveness of vibroacoustic therapy and logodotherapy on aggression in children with autism spectrum disorder

The aim of this study was to compare the effectiveness of vibroacoustic therapy and logodotherapy on aggression in children with autism. The research method was quasi-experimental pre-test-post-test with a control group and one-month follow-up. The statistical population of the study included 85 children aged 6-12 years with autism spectrum disorder who referred to two autism rehabilitation centers in Tehran (Shamim and Fariha centers) in the first half of 1398. Among them, 30 people (21 boys and 9 girls) were selected as a research sample by purposive sampling method and 10 people were randomly replaced in three groups of experiments (1, 2) and control. The first experimental group received vibroacoustic therapy for 12 sessions (20 minutes) and the second experimental group received logodotherapy for 12 sessions (45 minutes); The control group was placed on a waiting list. The Shahim Children's Aggression Questionnaire (2006) was used to collect information. In order to analyze the data, repeated measures analysis of variance and Bonferroni post hoc tests were used. Findings from the study showed that by controlling the effect of pre-test, there was a significant difference between the mean scores of aggression components (relational, verbal and physical aggression) in the experimental group and the control group in the post-test and follow-up. . Also, the findings showed that vibroacoustic therapy was more effective than legodotherapy in reducing aggression in children with autism.
