Introduction
The Adult ADHD Self-Report Scale (ASRS) version 1.1 is a diagnostic tool designed for the assessment of Attention-Deficit/Hyperactivity Disorder (ADHD) in adults. Developed in collaboration between the World Health Organization (WHO) and researchers at Harvard Medical School, the ASRS v1.1 is grounded in the criteria set forth in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR). The tool consists of 18 items that reflect the DSM-IV-TR criteria for ADHD, divided into two main symptom domains: inattention and hyperactivity-impulsivity.
The ASRS v1.1 is utilized for both screening purposes and for monitoring the severity of ADHD symptoms over time. This dual functionality allows it to be applied in a variety of clinical and research settings. The questions are structured to be self-reported, facilitating the collection of information directly from individuals regarding their symptoms.
The development of the ASRS v1.1 aimed to provide a standardized method for identifying ADHD in adults, addressing a need for reliable diagnostic tools in this population. Its format is designed to be user-friendly, supporting its widespread use among healthcare professionals. Validation studies have supported the reliability and validity of the ASRS v1.1 in identifying adult ADHD, indicating its effectiveness as a component of a comprehensive diagnostic process. Its application is seen as a step toward improving the accuracy of ADHD diagnoses and informing treatment planning in adults.
