Preferences of Iranian average risk population for colorectal cancer screening tests.

PURPOSE

The purpose of this paper is to explore the preferences of the average risk Iranian population for colorectal cancer (CRC) screening tests.

DESIGN/METHODOLOGY/APPROACH: A standard stated-preferences method with discrete choice models was used to identify the preferences. Data about socio-demographic status, health status and preferences for CRC screening tests were collected by a structured questionnaire that was completed by 500 people aged 50-75 years. Mixed logit model was used to analyze the preferences.

FINDINGS

The regression model showed that the test process, pain, place, frequency, preparation, sensitivity, complication risk, mortality rate and cost were the final attributes; that had a statistically significant correlation with the preferences of the people in choosing CRC screening tests. The socio-demographic and health status of participants had no significant correlation with the individuals' preferences.

PRACTICAL IMPLICATIONS

This study provides insight into how different characteristics of a CRC screening test might influence the preferences of individuals about that test.

ORIGINALITY/VALUE: This was the first study of this type in Iran to elicit the preferences of the average risk population for CRC screening tests using a discrete choice model.
