Plain English Summary
Background and study aims
Attention-Deficit/Hyperactivity Disorder (ADHD) is a prevalent condition in youths, with symptoms that include inattentiveness, hyperactivity and impulsiveness. It is associated with a significant impact on functioning and high costs. The aim of this study is to compare the effectiveness of a combined treatment (CBT/REBT + ATX) with two reference treatments (CBT/REBT and ATX) for ADHD symptoms in children.
Who can participate?
Children aged 6 to 11 with ADHD
What does the study involve?
Participants are randomly allocated to one of three groups. Participants in the psychotherapy group receive 16 weekly individual psychotherapy sessions, involving both parents and children, based on Cognitive Behavioral Therapy (CBT) and Rational Emotive Behavior Therapy (REBT) enhanced with one session of attention training delivered via virtual reality. Participants in the medication group receive atomoxetine (ATX) once daily. Participants in the combined group (ATX+ REBT/CBT) receive both medication and psychotherapy as previously described. The total duration of treatment is 16 weeks. Clinical psychologists and multiple assessors (parents, teachers) assess the participants' ADHD symptoms before and after treatment.
What are the possible benefits and risks of participating?
Possible benefits include free treatment for ADHD which is not covered in Romania by health insurance. Risks involving adverse medication effects, which are monitored by psychiatrists.
Where is the study run from?
1. The Institute for the Advanced Studies of Psychotherapy and Applied Mental Health, Babeș-Bolyai University (Romania)
2. The Clinic of Child and Adolescent Psychiatry (Romania)

Attention-Deficit/Hyperactivity Disorder (ADHD)
Randomization was done using a random number generator (www.random.org). Participants were randomly assigned to one of the three treatment groups:
1. Psychotherapy (cognitive-behavioral therapy/rational emotive behavior therapy CBT/REBT)
Participants in the psychotherapy condition received 16 weekly individual psychotherapy sessions, involving both parents and children. The protocol was based on Cognitive Behavioral Therapy (CBT) and Rational Emotive Behavior Therapy (REBT) enhanced with one session of attention training delivered via virtual reality (VR).
2. Medication (atomoxetine ATX)
Participants in the medication condition received atomoxetine (ATX) once daily in the morning, with an initial dose of 0.5 mg/kg/day, increased weekly (maximum increase 1.8 mg/kg/day).
3. Combined treatment (ATX+ REBT/CBT)
Participants in the combined group (ATX+ REBT/CBT) received both medication and psychotherapy as previously described.
The total duration of treatment was 16 weeks. Blinded clinical psychologists and multiple assessors (parents, teachers) assessed ADHD symptoms both at pretreatment and posttreatment.
Primary outcome measure
1. Clinician-based interviews on ADHD symptoms and impairment. ADHD diagnosis was assessed using the Structured Clinical Interview for DSM-IV Childhood Diagnoses (KID-SCID; Hien et al., 1994), while impairment was assessed using the Global Assessment of Functioning (GAF; APA, 1994); both conducted at baseline and post-treatment (16 weeks)
2. Parent-rated ADHD total symptoms, inattention and hyperactivity symptoms, measured using the ADHD-rating scale IV-Parent Version (ADHD-RS IV; DuPaul, Power, Anastopoulos, & Reid, 1998) at baseline and post-treatment (16 weeks)
Secondary outcome measures
1. Parent-rated externalizing and internalizing symptoms assessed using the Child Behavioral Checklist (CBCL; Achenbach & Rescorla, 2001) at baseline and post-treatment (16 weeks)
2. Teacher-rated ADHD total symptoms, inattention and hyperactivity symptoms assessed using The ADHD-rating scale IV-Teacher Version (ADHD-RS IV; DuPaul et al., 1998) at baseline and post-treatment (16 weeks)
3. Teacher-rated externalizing and internalizing symptoms assessed using Teacher’s Report Form (TRF; Achenbach & Rescorla, 2001) at baseline and post-treatment (16 weeks)
