For each type of cancer, patients are identified by stage of cancer, stage of treatment, age, and geographical location.
Clients continue to tell us how impressed they are with the high quality of our respondents. This is a result of:
- Source – we recruit patients personally at advocacy events and other patient events; cancer patients come in through the American Cancer Society website; we ask physicians and pharmacists to refer patients with the desired specs to us; and our reliable panelists refer others they know with like conditions
- Vetting – We vet each patient and caregiver who signs up both manually (looking at the answers to questions about the condition and treatment) and technologically (does their contact information match independent sources? are IP addresses unique?). If unsure, we contact the patient directly and discuss. Amazing how fraudulent entries will simply go away.
- Review of data – We gain agreements from our clients to review survey data to make sure it aligns with other information about the respondents; and we apply our knowledge of the condition and its treatments to flag possible fraudulent respondents.
These practices set our respondents apart from those screened across the general population (“please check all the conditions you have”). It takes more time and attention, but we feel the highest quality data is certainly worth it.
With more than 30 years in market research experience on both the client and supplier side, we are happy to give you advice on the design of your research. And since we know our panelist very well, we can advise you on the best way to work with them to get the insights you and your clients require.
