ImGo: A Novel Tool for Behavioral Impulsivity Assessment Based on Go/NoGo Tasks

Area of Science:

• Psychology
• Cognitive Neuroscience
• Psychometrics

Background:

• Impulsivity assessment is crucial for understanding various psychological and neurological conditions.
• Existing measures may have limitations in general population applicability or psychometric robustness.

Purpose of the Study:

• To introduce and validate ImGo, a novel behavioral impulsivity test.
• To establish the reliability and validity of ImGo for assessing impulsivity in the general population.

Main Methods:

• Three studies were conducted to assess ImGo's psychometric properties.
• Methods included test-retest reliability, split-half reliability, convergent validity (with self-report scales and Stop Signal Test), and discriminant validity (with other cognitive tests).
• Oculomotor inhibition (Anti-Saccades test) was also examined in relation to ImGo.

Main Results:

• ImGo demonstrated good test-retest and split-half reliability.
• Convergent validity was confirmed with existing impulsivity measures.
• Discriminant validity was established against related cognitive and executive functions.

Conclusions:

• ImGo is a reliable and valid tool for behavioral impulsivity assessment.
• Its suitability for the general population and availability in multiple languages support its use in international research and clinical practice.
• The open-source platform allows for flexible testing in laboratory or remote settings.
