There are online screeners that are designed to help diagnose health problems. Some of them include the Adult ADH Self-Report Scale Screener by the World Health Organization and the COPD Population Screener by the COPD Foundation.
The Adult ADH Self-Report Scale Screener was developed by the World Health Organization to be used as a self-screening tool to help people recognize symptoms or signs of Adult ADHD, as stated on ADHDAwarenessMonth.com. On the other hand, the COPD Population Screener involves answering five questions on the COPD Foundation’s website in order to find out if one is at risk for the disease, explains the COPD Foundation. The screener is validated to be used in the United States, and was published in April 2008 in the "Journal of Chronic Obstructive Pulmonary Disease."
