SIESTA Training + Treatment as Usual for ADHD
We developed a cognitive behavioral therapy for sleep problems in adolescents with ADHD. This includes seven individual sessions with the adolescent and two individual sessions with the parent(s)/guardian(s). Participants receive this CBT training called SIESTA next to their treatment as usual for ADHD symptomatology (mostly ADHD-medication). SIESTA: SIESTA is a CBT sleep training for adolescents with ADHD with a focus on sleep hygiene, motivational interviewing and planning and organization. Treatment as usual for ADHD: Participants continue their treatment as usual for ADHD.
Treatment as Usual for ADHD Only
Participants continue their treatment as usual for ADHD (mostly ADHD-medication). Treatment as usual for ADHD: Participants continue their treatment as usual for ADHD.
