Primary Outcome Measures

Name	Time	Method
<p>The QbMT feasibility examination will involve as a primary objective, the<br /><br>examination of the data flow in the use of QbMT to identify potential errors or<br /><br>technical issues that may be associated with the data collection and QbTest<br /><br>parameter calculation. We will further examine the validity of QbMT in<br /><br>individuals diagnosed with ADHD. All the available QbTest measures of activity,<br /><br>impulsivity, and attention will be included as measures of interest in this<br /><br>study. These are described in the Measures section of the protocol.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>The secondary objective of the QbMT study is to explore additional eye-movement<br /><br>variables and parameters that can be calculated from a mobile camera device and<br /><br>the mobile use of QbTest such as indices of activity, attention, and<br /><br>impulsivity, and compare this with individuals with and without ADHD. </p><br>
