Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study was to examine the effects of the Cogmed training program on working memory among youths 7 to 13 years old, while controlling presence and presentation of ADHD-related comorbidity. A secondary objective was to examine the generalization of effects to ADHD symptoms, non-verbal reasoning, attentional and executive functions, motor impulsivity, reading comprehension, and mathematical reasoning. Participants were under pharmacological treatment for ADHD combined type and a comorbidity. They were randomized into an experimental group that received the Cogmed program and an active control group that received a low-intensity comparison version of the training. They were evaluated at three time points: six weeks prior to intervention onset (T1), immediately prior to onset(T2), and one week following intervention completion (T3).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants completed the Cogmed WM training program at home.Each training session lasted from 30 to 45 minutes and was supervised by a parent. For five consecutive weeks, participants had to complete at least five sessions per week.

Study Groups

active control group

The program for the active control group is the same as for the experimental group, except that the degree of difficulty of the exercises remains low and invariable across trials, with three items needing to be recalled throughout.

the Cogmed program

12 exercises proposed in the Cogmed program. Eight of these target visuospatial WM and four target verbal WM. Eight exercises are preprogrammed for each session, for a total of 90 trials (Pearsons, 2014). The degree of difficulty of the trials increases as a function of the participant's performance. For each trial, the participant receives feedback on their performance.
