The dimensional approach does not require the arbitrary dichotomization of individuals into categories based on an all-or-none principle but positions individuals on a continuum [17]. Consequently, it is by definition focused on a nonclinical or a mixed population and is therefore less vulnerable to comorbidities involved in clinical ADHD and its variability in medical history [15, 18]. In addition, the approach offers a more powerful statistical test of any hypothesis because dichotomizing continuous variables results in the loss of potential useful information [15]. Consequently, the dimensional approach leads to a more accurate assessment of ADHD symptoms and provides better understanding of its etiology [19, 20]."}
