Clinical Trial Summary

This study examines the impact of cognitive training among participants with ADHD in Switzerland

Description:

The main aim of the experimental study is to investigate cognitive functioning, behavioral and neural levels in ADHD, both before and after cognitive training where there has been the addition of motivation elements. Near and far transfers effects of this new program are evaluated. For far transfers, ambulatory assessment is used to improve ecological validity. Neural activity has rarely been examined in cognitive training with ADHD participants, and that is why this study also includes FMRI measures. Long-term effects, defined as three and six months following the completion of cognitive training, are also investigated. This study focuses on children, adolescents and adults with ADHD. Indeed, cognitive training effects have been rarely studied over the lifespan.

• ADHD

Intervention

Other:
• Cognitive training
Participants will train at home during 25 sessions (about 45 minutes each) over a maximum of 5 weeks. Investigators will verify compliance via Internet and call participants and their legal guardians once a week. A reward system will be established with participants. Five sessions of metacognition (1 hour each) are added.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	ADHD symptoms for adults	The Conners' Adult ADHD Rating Scales (CAARS) higher values represent worse outcome The Conners' Adult ADHD Rating Scales (CAARS) is used to assess ADHD symptoms among adults (Conners et al., 1999) depending on the DSM-IV-TR (APA, 2000). This short version includes 26 items and 4 possible ratings from from 0 (not at all) to 3 (very much). This scale comprises four factors: (1) inattention, memory problems, (2) hyperactivity, restlessness, (3) impulsivity, emotional lability, (4) problems with self-concept and one ADHD index. score are summed. Range 0 to 100.	Change between two time points from baseline T1 to six week later T2 after cognitive training is assessed. Follow up is assessed at 3 months T3 and 6 months T4
Primary	ADHD symptoms for children	The Conners Scale, 3rd edition higher values represent a worse outcome Questionnaire is rated by the legal guardian. This questionnaire assesses ADHD symptoms.Score are summed. Score range 0 to 100.	Change between two time points from baseline T1 to six week later T2 after cognitive training is assessed. Follow up is assessed at 3 months T3 and 6 months T4
Secondary	Impulsivity	The Impulsivity Behavior Scale (UPPS) higher values represent a worse outcome. score are summed short version contains 20 items measuring the following five dimensions of impulsivity: positive urgency, negative urgency, lack of perseverance, lack of premeditation and sensation seeking. This scale is based on Cyder and Smith (2007) and Whiteside and Lynam (2001) theory of impulsivity. Range 0 to 50.	Change between two time points from baseline T1 to six week later T2 after cognitive training is assessed. Follow up is assessed at 3 months T3 and 6 months T4
Secondary	executive function	The Behavior Rating Inventory of Executive Function higher values represent a worse outcome Score are summed. This questionnaire measures executive functionning in everyday life. The BRIEF includes 75 questions and eight sub-domains: Inhibit Shift, Emotional Control, Initiate, Working Memory, Plan/Organize, Organization of Materials and Monitor. Score range 0 to 100	Change between two time points from baseline T1 to six week later T2 after cognitive training is assessed. Follow up is assessed at 3 months T3 and 6 months T4
Secondary	Reward	Subjects will perform a reward under stress task adapted from the spatial delayed response task from (Glahn et al., 2002) measure reward (Martin-Soelch, C., et al.,2009: Gaillac et al., 2016). Reaction time is calculated.; The sensitivity to Punishment and Sensitivity to Reward questionnaire for Children, adolescents (SPSRQ-C) (Colder and O'Connor 2004) and adults (SPSRQ, Torrubia, Ávila, Moltó, & Caseras, 2001) are used. These questionnaires are based on Gray's reinforcement sensitivity theory of personality (1981, 1987, 2000). Reward task higher values represent a better outcome. Score range 0 to 110.	Change between two time points from baseline T1 to six week later T2 after cognitive training is assessed. Follow up is assessed at 3 months T3 and 6 months T4
Secondary	Reward	The sensitivity to Punishment and Sensitivity to Reward questionnaire for Children, adolescents (SPSRQ-C) (Colder and O'Connor 2004) and adults (SPSRQ, Torrubia, Ávila, Moltó, & Caseras, 2001) are used. These questionnaires are based on Gray's reinforcement sensitivity theory of personality (1981, 1987, 2000). Reward task higher values represent a better outcome. Score range 0 to 110.	Change between two time points from baseline T1 to six week later T2 after cognitive training is assessed. Follow up is assessed at 3 months T3 and 6 months T4
Secondary	Memory	WISC-IV higher values represent a better outcome. The Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV, Wechsler, 2003) Score are standardized from 0 to 20 for subtest and summed from 0 to 150.; The Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV, Wechsler, 2003) and the Weschler adult intelligent scale measure verbal memory. Score are standardized from 0 to 20 for subtest and summed from 0 to 150.	Change between two time points from baseline T1 to six week later T2 after cognitive training is assessed. Follow up is assessed at 3 months T3 and 6 months T4 training 4. Six months after cognitive training

Score are standardized from 0 to 20 for subtest and summed from 0 to 150.; The Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV, Wechsler, 2003) and the Weschler adult intelligent scale measure verbal memory. Score are standardized from 0 to 20 for subtest and summed from 0 to 150.	Change between two time points from baseline T1 to six week later T2 after cognitive training is assessed. Follow up is assessed at 3 months T3 and 6 months T4 training 4. Six months after cognitive training
Secondary	Neural activity	The fMRI measure include. Resting-state functional MRI.Task-free. Subjects are instructed to just lie quietly in the scanner and to think of nothing in particular and let their mind wander.- binding potential (?BP) is measured.	Change between two time points from baseline T1 to six week later T2 after cognitive training is assessed. Follow up is assessed at 3 months T3 and 6 months T4
