Scoring the Autonomic Symptom and Severity Rating (ASRV) Checklist
The ASRV symptom checklist is scored by rating each autonomic symptom on a scale of 1-3 based on severity, with 1 indicating mild symptoms, 2 indicating moderate symptoms, and 3 indicating severe symptoms. 1
General Scoring Principles
- The ASRV considers both the site of symptoms and symptom severity before and after treatment 1
- Each affected symptom complex is rated on a 1-3 scale (1=mild, 2=moderate, 3=severe) 1
- The total score is calculated by summing the severity ratings across all symptoms 2
Domains Typically Assessed
- Orthostatic symptoms (symptoms that occur upon standing) 3
- Vasomotor symptoms (related to blood vessel function) 4
- Sudomotor symptoms (related to sweating) 2
- Gastrointestinal symptoms 2
- Urinary symptoms 2
- Sexual dysfunction 2
- Pupillomotor symptoms (related to pupil function) 4
Interpretation Guidelines
- Higher scores indicate greater autonomic symptom burden 4
- Scores can be compared against normative data to determine the degree of autonomic dysfunction 5
- The scale shows good correlation with other validated autonomic measures such as the Autonomic Symptom Profile (ASP) 2
Clinical Application
- The ASRV can be used to monitor changes in autonomic symptoms over time 2
- It can help assess response to treatment interventions 1
- The scale has demonstrated good internal consistency and reliability (Cronbach α=0.76) 2
- It shows high sensitivity and specificity for detecting autonomic dysfunction 2
Practical Administration Tips
- Ensure all domains are assessed completely 4
- Document baseline scores before initiating treatment 1
- Re-assess at regular intervals to track symptom progression or improvement 2
- Consider using alongside objective autonomic function tests for comprehensive evaluation 5
