摘要：The aim of this study was to determine the effectiveness of Functional Training (FT) on impulsiveness of female students with Intellectual Disability (ID). The research method was pretestposttest- with a control group. The statistical population consisted of all female students with ID in elementary school of Shiraz studying under the auspices of the Special Education Organization in 2018- 2019. The participants included 30 female students with ID selected through convenience sampling and randomly assigned to the experimental (n=14) and control (n=14) groups. The experimental group received the functional training for 15 sessions, while the control group did not receive any intervention. The Barratt Impulsiveness Scale Version 11 (BIS-11) was used for measuring the impulsiveness. The Impulsiveness pre-test was performed for both experimental and control groups. The experimental group received the FT for 15 sessions, while the control group did not receive any intervention. At the end of the intervention, post-test was performed for both groups. Mann-Whitney U test was used to analyze the data. The results showed that the mean scores of impulsivities and its subscales (motor impulsiveness, attentional impulsiveness and nonplanning impulsiveness) in the experimental group were significantly reduced. The results showed that FT had a significant effect on impulsiveness of female students with ID (p<0.001). Therefore, it is recommended to design and implement a FT program to improve impulsiveness in people with ID.
