An internet-based method of selecting control populations for epidemiologic studies

Area of Science:

• Epidemiology
• Public Health
• Health Research Methodology

Background:

• Traditional methods for recruiting control subjects in epidemiologic studies face increasing challenges.
• Changes in telephone technology, including answering machines, caller ID, and mobile phones, hinder subject identification and contact.
• The difficulty in obtaining representative control groups impacts the validity of epidemiologic research findings.

Purpose of the Study:

• To describe a novel internet-based method for identifying and recruiting study subjects.
• To address the challenges posed by modern telecommunication technologies in subject recruitment.
• To enhance response rates in epidemiologic studies through an improved recruitment strategy.

Main Methods:

• Developed and tested an internet-based recruitment strategy.
• Utilized information from two distinct websites to compile comprehensive subject lists.
• Combined data to generate accurate lists of names, addresses, and listed telephone numbers.
• Applied the method to randomly selected streets in a Salt Lake City suburb in June 2005.

Main Results:

• The described internet-based method successfully generated accurate and complete lists of potential study subjects.
• The approach integrates data from multiple online sources for robust subject identification.
• This method offers a viable alternative to traditional recruitment techniques facing technological barriers.

Conclusions:

• The developed internet-based approach provides an effective solution for identifying control subjects in epidemiologic studies.
• This method can potentially overcome challenges associated with declining landline usage and increasing mobile phone prevalence.
• Implementing this strategy may lead to improved participant recruitment and enhanced data quality in health research.
