ASRS v1.1 Implementation Guide
A comprehensive guide to the Adult ADHD Self-Report Scale (ASRS) v1.1, how we implement it, and what you need to know about this gold-standard screening tool.
What is the ASRS v1.1?
The Adult ADHD Self-Report Scale (ASRS) v1.1 is a scientifically validated screening tool developed by the World Health Organization (WHO) and Harvard Medical School. It's designed to identify adults who may have ADHD and is widely used by healthcare professionals worldwide.
ASRS v1.1 Structure
- Part A (Questions 1-6): Core ADHD symptoms that must be present for a diagnosis
- Part B (Questions 7-18): Additional symptoms that support an ADHD diagnosis
- Scoring: Each question is scored based on frequency of occurrence
How We Implement the ASRS v1.1
Our implementation follows the official ASRS v1.1 guidelines while adapting the format for online use. We maintain the scientific integrity of the original tool while making it accessible and user-friendly.
Our Implementation Approach
- • Faithful to Original: We use the exact same questions and scoring criteria as the official ASRS v1.1
- • Digital Adaptation: Questions are presented in a clear, distraction-free online format
- • Privacy-First: No data is stored or transmitted to our servers
- • Educational Focus: Results are presented with clear explanations and next steps
How We Score
Part A Scoring
Positive: 4 or more symptoms marked as "Often" or "Very Often" in the past 6 months
Not Positive: Fewer than 4 symptoms at this frequency level
Part B Count
Total number of symptoms (out of 12) marked as "Often" or "Very Often" in the past 6 months
Work Friction Index (WFI)
Proprietary composite score (0-100): Non-clinical measure for work impact planning
Calculated as: (Part A score ÷ 6 × 0.7) + (Part B score ÷ 12 × 0.3) × 100
