it was not common for clinical psychologists to administer an IQ test as a standard part of an Attention Deficit Disorder (ADD) or Attention Deficit Hyperactivity Disorder (ADHD) diagnosis. The diagnosis of ADHD typically involves a comprehensive assessment that includes gathering information from various sources, such as the individual's history, parent/teacher interviews, behavioral observations, and rating scales.
The primary diagnostic criteria for ADHD are based on the presence and severity of specific symptoms, such as inattention, hyperactivity, and impulsivity, as outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), which is the standard reference for mental health professionals.
IQ tests may be used in some cases, but they are not a central component of diagnosing ADHD. However, assessing cognitive functioning, including IQ, can be valuable in understanding an individual's strengths and weaknesses, especially if there are concerns about potential learning disabilities or intellectual giftedness that could be impacting their academic performance or daily functioning.
It's important to note that practices and guidelines might evolve over time, and different professionals may have varying approaches to assessment. Therefore, for the most up-to-date and accurate information, it's always best to consult with a licensed clinical psychologist or mental health professional who specializes in ADHD evaluations. They will be able to provide you with the most appropriate and relevant assessment procedures for diagnosing and understanding the individual's needs.
