In this regard, this study aimed to determine the effectiveness of a mindfulness-based intervention that has recently been introduced to improve impulsivity and risk-taking behaviors in adolescents with ADHD. Method: The present research was a single-subject experimental study with multiple baselines and follow-up. The study sample consisted of four adolescents with ADHD in the age range of 15 to 18 years who had been randomly selected from a clinical center in Rasht in 2020-2021. To measure the research variables, the Barratt Impulsivity Scale (Patton et al., 1995) and the Iranian Adolescents Risk-taking Scale (Zadeh Mohammadi et al., 2011) were used. The mindfulness and modification treatment (MMT) was implemented in 12 weekly 45-minute sessions, each of which included a 3 to 16-minute mindfulness exercise and a review of previous homework and presentation of new homework. The effect size, reliable change, and percentage of non-overlapping data were used to assess statistical significance; improvement percentage was used to assess clinical significance. Results: The findings showed that according to three indices of reliable change, effect size, and percentage of non-overlapping data, the effectiveness of this intervention in reducing impulsivity and risk-taking behaviors was statistically significant, but the improvement percentage index could not show its clinical significance. Conclusion: According to the findings, it can be concluded that MMT by affecting awareness of present experience and strengthening emotion regulation can reduce impulsivity and risk-taking behaviors.
