Efficacy and acceptability of a second dose of ecological executive skills training for children with ADHD: a randomized controlled study and follow-up.

To explore the efficacy and acceptability of a second dose of the 12-session ecological executive skills training (EEST) 1 year after the initial training in children with ADHD. A total of 97 children (aged 6-12) with ADHD who finished the first dose for about 1 year were recruited in the current study. 70 children who agreed to participate the second dose were randomized to the second dose or waitlist group. Both groups were followed up 1 year after the second dose. Executive function, core symptoms were assessed at the time of pre-intervention first dose, pre-intervention second dose, post-intervention second dose and follow-up 1 year after second dose (phase 0-3). For the immediate efficacy, the improvements in the second dose group were greater than the waitlist group on planning by Stockings of Cambridge and delay aversion by Cambridge gambling task (P = 0.02-0.04, η2 = 0.07-0.08). The parent rating of symptoms assessed by ADHD-RS-IV of the second dose group were also greater than the waitlist group rated by self-report. For long term efficacy, Linear mixed model indicated that there was significant time effect for both groups between phase 3 and phase 1, phase 1 and phase 0 on Behavior Rating Scales of Executive Function and ADHD-RS-IV (F = 2.849-21.560, P = 0.001-0.048). The compliance rate was 94.3% for the second dose group and 49% for waitlist group. A second dose of EEST program might bring further efficacy of EF and core symptoms for children with ADHD and it was well accepted.
