Evaluating Knowledge, Attitudes, and Beliefs About Lung Cancer Screening Using Crowdsourcing

Area of Science:

• Pulmonology
• Oncology
• Public Health

Background:

• Lung cancer screening has a proven mortality benefit but remains underutilized.
• Previous studies had limited generalizability due to recruitment strategies and focus on specific subpopulations.
• This study employed crowdsourcing for broader population assessment of screening knowledge, attitudes, and beliefs.

Purpose of the Study:

• To assess knowledge, attitudes, and beliefs regarding lung cancer screening in a broad, high-risk population.
• To identify factors associated with willingness to undergo lung cancer screening.
• To inform strategies for increasing lung cancer screening rates.

Main Methods:

• A 31-item survey was developed to assess knowledge, attitudes, and beliefs about lung cancer screening.
• Crowdsourcing via Amazon's Mechanical Turk was used for participant recruitment.
• Survey data from 240 qualified respondents were analyzed.

Main Results:

• Only 44% of respondents knew about lung cancer screening, and 35% correctly identified low-dose CT scans.
• 93% believed early detection saves lives, and 69% were willing to be screened if recommended by a physician.
• Knowledge of screening, smoking status, chronic pulmonary disease, and belief in early detection efficacy were associated with willingness to screen.

Conclusions:

• A minority of high-risk individuals are aware of lung cancer screening, despite its benefits.
• The majority of individuals believe in early detection and would screen if recommended by their physician.
• Improving patient and physician awareness is crucial for increasing lung cancer screening rates.
