Objective  To explore the application value of support system which is based on new media in the management of children with attention-deficit/hyperactivity disorder (ADHD). Methods  Children with ADHD who were visited and filed at Department of Child Healthcare，Xuzhou Childrens Hospital from October 2017 to July 2018 and their families were selected as the research objects. In the form of voice teaching，interactive communication and so on，the research group (new media management group) achieved 10-month management with the help of Wechat APP. The control group conducted file management through ADHD outpatient follow-up. All objects achieved evaluation by using SNAP-Ⅳ parent rating scale，Conners teacher rating scale，and children's self-awareness scale before and after admission. Results  The factor scores of SNAP-Ⅳ parental rating scale and Conners teacher rating scale all decreased after training as compared with the baseline. The difference was statistically significant (P<0.01). In terms of intelligence，school，happiness，satisfaction，and total scores of children's self-awareness scale，the differences were also statistically significant (P<0.01). In terms of the physical appearance and group factor scores in the research group，there were also significant differences (P<0.01). Attention deficit and impulsive hyperactivity factor score had statistical differences in different management styles and different research groups（P＜0.05），and the factor score of opposite and defiance had a statistically significant  difference (P<0.01). There was statistical difference in the application proportion of first-line drugs between the two groups after using different management styles（χ2=3.908，P=0.048）. Conclusion  New media management is more efficient and convenient in the management of ADHD. It is beneficial to the whole process，and  the standardized and systematized management of ADHD. The core symptoms of ADHD children，the follow-up rate，and the application rate of first-line drug can be comprehensively improved.
