The goal of this study is to provide a new treatment approach for schoolage children with ADHD, which could facilitate the EF developing well to achieve better outcome.

ADHD in preschoolers has become established as a valid psychiatric disorder with characterized core deficits of executive function (EF). The EF impairments occurred in preschool period could persist to childhood, adolescent and adulthood, causing extensive and deep damage of individual's academic and career achievement, social function, and peer relationship. Although medication showed significant effectiveness in controlling the core symptoms of ADHD, it failed to help patients master compensatory strategies to cope with functional impairments in learning and life events. The family intervention program for school-age ADHD children is still rare, and it is a blank field in China. At present, most of these related studies have not integrated task training in realistic scenarios with parent training, and lack of randomized and controlled Settings, which makes the effect of intervention less convincing. Therefore, the investigators conduct this randomized and controlled study to find out the therapeutic efficacy of Family-based Executive Function Training for Schoolage Children with ADHD, and follow the subjects to observe whether the therapeutic efficacy would persist. In the mean time, the investigators also observe the factors which can influence the therapeutic efficacy. The goal of this study is to provide a new treatment approach for schoolage children with ADHD, which could facilitate the EF developing well to achieve better outcome.
