What is ADHD?

Attention-deficit/hyperactivity disorder, or ADHD for short, is a developmental disorder where people find it challenging to keep their attention on something for long, and their attention is often pulled into different directions. A person with ADHD will also become impulsive and hyperactive.

ADHD can significantly affect a person's daily life and overall mental well-being, depending on the severity of the disorder and the individual's ability to manage their symptoms. Some common symptoms include frequent mood swings, frustration, hot tempers, restlessness, and a tendency to jump from one activity to another. Individuals with ADHD may also struggle to complete tasks, maintain focus, prioritize effectively, stay organized, and plan well. Recognizing these challenges is essential for better understanding and support.

Children exhibiting hyperactivity and impulsivity may leave a negative impression on peers and teachers, often being perceived as disruptive or unfocused, which can lead to social isolation and difficulties in forming friendships (Thompson et al., 2023). Conversely, these children may also demonstrate unique strengths, such as creativity and high energy, which can leave a positive impression when channeled appropriately in environments that support their needs.

There are numerous ADHD scales to choose from when assessing a child for ADHD. One group of ADHD scales that healthcare professionals, parents, and teachers can use is the Conners' Rating Scale. This scale is a valuable ADHD assessment tool that measures different aspects of a child's behavior, such as inattention and hyperactivity.

What is the Conners' Rating Scale?

The Conners’ Rating Scale is a widely utilized assessment tool designed to evaluate the presence and severity of ADHD symptoms in children and adolescents. This comprehensive scale is available in various formats, including a Conners parent rating scale and a Conners teacher rating scale, enabling a multi-faceted approach to diagnosis by gathering perspectives from different environments. The Conners scale assesses symptoms such as impulsivity, hyperactivity, and inattention, making it a valuable resource for healthcare professionals.

Parents can download a Conners' Rating Scale PDF called Conners' Rating Scale - Parent (Revised - L) designed for their use for easy reference and completion, while teachers can use the Conners questionnaire for teachers to provide insights that contribute to a holistic understanding of a child's behavior at school. Utilizing both the Conners test and related assessment tools ensures a thorough evaluation, guiding effective intervention strategies for managing ADHD.

Parents and healthcare professionals can also benefit from the Conners 3rd Edition, a comprehensive multi-informant assessment designed to assist in the diagnosis and monitoring of ADHD while also identifying other behavioral, emotional, and academic challenges. Building on the solid findings of its predecessor, the Conners’ Rating Scales-Revised (CRS-R), the Conners 3 the latest version of the scales, strongly emphasizes ADHD and its related characteristics while also addressing comorbid conditions such as oppositional defiant disorder and conduct disorder (Conners et al., 2011). It includes self-report forms and teacher forms to be used depending on the assessment's purpose.

How to use the Conners' Rating Scale - Parent (Revised - L)

This version of the Conners' Rating Scale for Parents is from Conners' 1997 work, The Conners Rating Scales – Revised Manual, designed to comprehensively evaluate a child's behavior and assess the presence and severity of ADHD symptoms. This scale consists of 80 items to be rated by parents based on their child's behavior over the past month. Each item is rated using the following options:

Not true at all = 0 points
Just a little true = 1 point
Pretty much true = 2 points
Very much true = 3 points

After parents complete the scale, the scores are totaled. Healthcare professionals typically use the T-score standardized measure to interpret the results:

A T-score below 60 suggests no ADHD.
A T-score above 60 indicates possible ADHD.
A score above 70 suggests severe ADHD symptoms.

Keep in mind that the Conners' Rating Scales are just one tool for assessing ADHD. It's advisable to use additional rating scales to ensure consistency and to cross-check findings against the latest ADHD criteria from the Diagnostic and Statistical Manual of Mental Disorders.

It's an easy scale to answer

This version of the Conners' Rating Scale may be lengthy, but it offers a straightforward way to respond. Parents will simply need to evaluate their child for each item based on their behavior over the past month. There’s no requirement for detailed explanations; this will come later during the comprehensive evaluation for children suspected of having ADHD. Parents only need to select one of the four answer options that best describes their child for each statement. Completing the scale should take no more than twenty minutes.

The scale can help professionals decide what to do next

This version of the Conners' Rating Scale is beneficial as it addresses various problems commonly associated with potential ADHD in children.

It can be used to monitor the child later on

ADHD screening tools can be used repeatedly to monitor progress in children diagnosed with ADHD. If you're still in touch with the parents, schedule routine checkups and provide them with another copy of the scale. A lower score indicates that the treatment plan is effective, while a higher score may require adjustments or more time.
