Randomized control study of the effects of executive function training on peer difficulties of children with attention-deficit/hyperactivity disorder C subtype.

Attention-deficit/hyperactivity disorder C subtype (ADHD-C) is associated with social rejection and peer difficulties. The present study evaluates the comparative efficacy of group executive function training (GEFT) with social skills training (SST) in children with ADHD-C in China. A randomized, controlled treatment outcome study that comprised of 52 boys and 29 girls (age range: 9-12years old) was conducted. The primary variable (peer relationship), secondary variables (executive functions [EFs] and social skills) and ADHD symptoms (inattention and hyperactive) were measured before and after the intervention and 3-month follow-up. First, both GEFT and SST had instant effects on peer relationship. Second, GEFT mainly improved their EFs and self-control dimension of social skills. At the same time, ADHD symptoms were reduced. SST mainly improved their social skills, but had no effect on EFs and ADHD symptoms. Third, GEFT had better long-term effects than SST on peer relationship. Executive function training produced more effective and lasting changes on peer difficulties of ADHD children.
