The purpose of the present study was to compare the effects of aromatherapy, play, and the combination of those on aggression of adolescents with educable intellectually disability. Therefore, 50 students (23 girls, 27 boys) aged 12- 16 years with educable intellectually disability were selected from a special elementary school as convenience and were assigned randomly to 4 groups, including aromatherapy, play, combination, and control. The B.D.GH aggression inventory was used to measure the amount of aggression in pretest and posttest. During 8 weeks (2 sessions per week), aromatherapy group inhaled Lavender essence, play group performed the selected plays, combination group inhaled Lavender and performed the selected plays, and control group did not perform any activities. Two-way (group*test) analysis of variancewith repeated measures of last factor were used to analyze data in p<.05. According to the results, the amount of aggression and verbal and nonverbal aggression to others subscales decreased after 8 weeks of aromatherapy, play, and combination of those, but there were no significant differences between the effects of various interventions. Thus, Interventions of aromatherapy, play or the combination of those can be similarly effective to reduce aggression in adolescents with educable intellectually disability.
