Background & objective: Due to the consequences of attention deficit - hyperactivity disorder, various therapy approach have been formed. This research aimed to investigate a comparative study between Barkley behavioral therapy, Minuchin structural family therapy and neuro-feedback on anxiety among children suffering from attention deficit – hyperactivity disorder. Methods: This study was a quasi - experimental pretest-posttest with a control group. The study population consisted of all primary school student in Karaj in 2018. By using cluster sampling method, 400 students selected and screening conducted for hyperactivity and anxiety. The sample consisted of 40 (10 for each group) students and their mothers were selected by as an available and randomly recruits to each of groups. Instruments for gathering data were semi-structured diagnostic interview (K-SADS), short diagnostic scale for hyperactivity and attention deficit disorder (Caners, 1999) and multidimensional child anxiety scale (March et al., 1997). Then, the participants in the experimental groups (Three groups) participated in Barkley behavioral therapy (9 sessions of 90 min), Minuchin structural family therapy (8 sessions of 90 min) and neuro-feedback (25 sessions of 30 min), while the control group did not receive any intervention. Then, the data were analyzed using SPSS.v21 software and statistical tests such as MANCOVA and ANCOVA. Data analysig was performed with SPSS.v16 and significant levels of all tests set on 0.05. Results: The results indicate that Barkley behavioral therapy, Minuchin structural family therapy and neuro-feedback have significant impact on anxiety among children suffering from attention deficit – hyperactivity disorder, generally (P < 0.01). Furthermore, post-hoc test revealed that the efficacy of therapies on anxiety of experiment groups is different (P < 0.01). Three months follow-up results represent resistance of therapies (P > 0.01). Conclusion: So, using of these therapies for reduction of anxiety among children suffering from attention deficit – hyperactivity disorder. Key words: Barkley behavioral therapy, Minuchin structural family therapy, neuro-feedback, anxiety, attention deficit – hyperactivity disorder
