Understanding ADHD: How a Psychologist Can Help with an ADHD Assessment

ADHD is a neurodevelopmental disorder marked by a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with daily functioning. It typically begins in childhood and can continue into adulthood. ADHD is more commonly diagnosed in males, though it often presents differently in females, sometimes making it harder to identify.

A psychologist can determine which type of ADHD a person may have:

1. Predominantly inattentive type

2. Predominantly hyperactive-impulsive type

3. Combined presentation (both inattentive and hyperactive-impulsive symptoms)

Inattentive symptoms may include:

• Difficulty sustaining attention or following instructions

• Making careless mistakes or losing things

• Avoiding tasks that require prolonged focus

• Being forgetful or easily distracted

Hyperactive-impulsive symptoms may include:

• Fidgeting, restlessness, or difficulty staying seated

• Excessive talking or interrupting others

• Impulsive behaviour, such as blurting out answers

• Struggling to wait turns or follow routines

For a formal diagnosis, symptoms must cause significant impairment in social, academic, or occupational functioning and be present in two or more settings (home, school, work, or social situations).

It is common for ADHD to co-occur with other disorders, such as:

• Anxiety or depression

• Learning disorders (e.g., dyslexia)

• Oppositional Defiant Disorder (ODD) or Conduct Disorder

A psychologist specialising in ADHD can provide a thorough ADHD assessment that:

• Evaluates whether diagnostic criteria for ADHD are met

• Identifies cognitive strengths and weaknesses

• Offers personalised recommendations for treatment

• Provides guidance for special consideration in school, university, or work

Psychologists can also implement evidence-based behavioural strategies to manage ADHD symptoms. However, they do not prescribe medication. If medication is indicated, a referral to a psychiatrist or paediatrician is recommended.

At Eastside Psychology Clinic, ADHD assessments for children and adults are comprehensive, taking approximately 3 hours. Assessments include:

1. Clinical Interview

During the interview, the psychologist gathers detailed information about:

• Developmental, educational, and employment history

• Behavioural, social, and psychiatric history

• Medical and substance use history

• Academic performance and learning challenges

This process ensures that ADHD symptoms are not better explained by another condition.

2. Cognitive Testing

Standardised tests are used to assess:

• Intellectual abilities (verbal comprehension, working memory, processing speed)

• Sustained attention and executive functioning

• Academic skills, if needed (reading, writing, or numeracy)

Commonly used tests include:

• Wechsler Intelligence Scale for Children – 5th Edition (WISC-V)

• Wechsler Adult Intelligence Scale – 4th Edition (WAIS-IV)

• Delis-Kaplan Executive Functioning System (D-KEFS)

• Wisconsin Card Sorting Test (WCST)

3. Questionnaires

• For children: parents, teachers, and the child complete questionnaires about ADHD symptoms

• For adults: the client and, if possible, a close family member complete ADHD rating scales

4. Report and Recommendations

After scoring and interpreting all results, the psychologist prepares a detailed report (usually 10–12 pages), typically delivered within 2–3 weeks. The report includes:

• Assessment results

• Recommendations for treatment or support

• Guidance for educational or workplace accommodations

If you or your child are struggling with attention, impulsivity, or hyperactivity, a comprehensive ADHD assessment can provide clarity and direction. Early identification and intervention improve academic performance, social functioning, and overall wellbeing.
