There are several types of assessments and tests used to evaluate and diagnose Attention-Deficit/Hyperactivity Disorder (ADHD). These tests help clinicians gather information about an individual’s symptoms, behavior, and functioning to make an accurate diagnosis. Here are some common types of ADHD tests:

• Behavioral Rating Scales: These questionnaires are typically completed by parents, teachers, or the individual themselves to assess ADHD-related behaviors, including symptoms of inattention, hyperactivity, and impulsivity. Examples include the ADHD Rating Scale-IV (ADHD RS-IV) and the Conners’ Rating Scales.
• Clinical Interviews: A clinician conducts interviews with the individual and, if applicable, with parents, teachers, or caregivers to gather information about the person’s behavior, development, and ADHD symptoms.
• Continuous Performance Tests (CPT): These computerized tests measure sustained attention and impulsivity by presenting stimuli to the individual and recording their responses. The Test of Variables of Attention (TOVA) is an example of a CPT often used in ADHD assessments.
• Conners’ Continuous Performance Test (CPT): This is a widely used CPT specifically designed to assess attention and impulsivity in individuals with ADHD.
• Executive Functioning Assessments: These assessments evaluate a person’s ability to plan, organize, and self-regulate behavior, which are commonly affected in individuals with ADHD.
• Cognitive Assessments: Cognitive tests, such as tests of working memory and processing speed, can provide valuable information about attentional and cognitive functions.
• Observations: Direct observations of the individual’s behavior and interactions in various settings, such as school or home, can provide valuable insights into their ADHD-related behaviors.
• Functional Assessment: This type of assessment explores how ADHD symptoms impact the individual’s daily functioning, including academic performance, social interactions, and emotional well-being.
• Diagnostic Criteria-Based Assessments: These assessments use standardized criteria, such as those outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), to determine if the individual meets the diagnostic criteria for ADHD.

A comprehensive ADHD assessment typically involves a combination of these tests and assessments. It is important for the evaluation to be conducted by qualified professionals experienced in ADHD diagnosis and assessment to ensure accurate results and appropriate treatment recommendations.
