MOXO Ecologically Validate Distractors System
Standard CPT tests which evaluate ADHD symptoms and specifically the patients’ attention abilities are performed in laboratory conditions in a quiet room, secluded from distractions. However, researchers believe that such results don’t fully reflect the patient’s conduct and day-to-day behavior in which they are faced with a constant stream of diversions and disturbances to their environment (e.g., Barkley, 1991).
The DSM-5 (Diagnostic and Statistical Manual of Mental Disorders) defines the diagnostic criteria for ADHD and mentions external stimuli distractibility (“Is often easily distracted by extraneous stimuli”) as a measure of one of ADHD symptoms of inattentiveness.
MOXO test contains a set of distractors that aims to simulate a real-life environment and thus improve the validity of the assessment in relation to everyday life. The effect of distractors was tested on ADHD and control participants in numerous clinical studies
(1-Berger et el., 2015; 2-Berger et el., 2014; 3-Berger et el., 2013).
MOXO’s distractors set was designed to fit specific age groups in each test version: MOXO Kids and MOXO Teens & Adults contain short animated videos and audio distractors sections that are irrelevant to the task being performed. They can be visual only, auditory only, or a combination of the two. The test is divided into eight levels and various types of distractors appear throughout the separate stages of the test, as described here:
Basic 1 – Baseline level, no distractors
Level 2 – Low load of visual distractors
Level 3 – High load of visual distractors
Level 4 – Low load auditory distractors
Level 5 – High load auditory distractors
Level 6 – Combination of Low load visual and auditory distractors
Level 7 – Combination of High load visual and auditory distractors
Basic 2 – No distractors (identical to Basic-1)
