Attention-Deficit/Hyperactivity Disorder Test (ADHD-I)

The ADHD-I was developed by IDRlabs, inspired by ADHD research, including the work of Dr. Russell Barkley, Dr. Thomas Brown, and DSM-5 criteria. The ADHD-I is not associated with specific researchers or institutions.

The test measures following aspects:

Inattention: Individuals high in this trait struggle with sustaining attention, organizing tasks, or following through on instructions. They may be easily distracted or forgetful, reflecting core DSM-5 criteria for ADHD (APA, 2013).

Hyperactivity-Impulsivity: People with high scores exhibit restless behavior, difficulty waiting, or impulsive decision-making. This aligns with DSM-5 criteria and research on motor inhibition deficits in ADHD (Barkley, 1997).

Emotional Dysregulation: Individuals high in this trait experience intense emotions or difficulty managing frustration, often linked to prefrontal cortex dysfunction in ADHD (Shaw et al., 2014).

Executive Function Challenges: People with this trait struggle with planning, prioritizing, or self-monitoring, reflecting deficits in executive functioning common in ADHD (Brown, 2013).

Time Management Difficulties: Individuals high in this trait have trouble estimating time or meeting deadlines, often described as “time blindness” in ADHD literature (Barkley, 2012).

Hyperfocus: People with high hyperfocus engage intensely in tasks of interest, sometimes to the exclusion of other responsibilities, a phenomenon noted in ADHD (Hupfeld et al., 2019).

Motivational Difficulties: Individuals high in this trait struggle with initiating tasks or sustaining effort without immediate rewards, tied to dopamine dysregulation in ADHD (Volkow et al., 2011).

Cognitive Restlessness: People with this trait experience racing thoughts or mental restlessness, often reported in adult ADHD (Weyandt et al., 2017).

This free online ADHD-I screens for ADHD traits. We have striven for reliability and validity through statistical controls, but this test does not provide professional assessments. Consult our Terms of Service for details.
