The present study aimed to investigate the effect of SPT on aggression and emotional adjustment of children with a hearing impairment aged 5–7 years. Methods: In this quasi-experiment study with a pretest-posttest design and a control group, 30 children aged 5–7 years with hearing impairment participated. They were randomly assigned into two groups: control and experimental. The research instruments were Sinha and Singh adjustment questionnaire and the Shahim aggression questionnaire. The obtained data were analyzed using multivariate covariance analysis. Results: There were statistically significant differences (score decrease) between the two study groups after the SPT in terms of aggression (p<0.05) and the emotional adjustment of children (p<0.05). Conclusion: The results showed that SPT could decrease aggression and improve emotional adjustment in children with hearing loss. This method can be used to rehabilitate these children. https://avr.tums.ac.ir/index.php/avr/article/view/1096
