Risk Communication in African American Smokers

November 27, 2023 updated by: Temple University

Nicotine Dependence and Lung Cancer Genetics in African Americans

The study aims to understand the effects of learning about one's genetic risk for lung cancer that is specific to their ancestry. Participants will be given hypothetical personalized genetic risk results and ask to think about how they might respond to such information if they actually received such results.

Study Overview

Detailed Description

The study aims to understand the effects of learning about one's genetic risk for lung cancer that is specific to their ancestry. Smokers will be randomized to receive hypothetical information about their genetic status and consider how they think they would respond if such results were actually presented to them. They will be randomly assigned to receive one of four sets of hypothetical genetic results: 1) High risk of lung cancer and high genetic African ancestry, 2) High risk of lung cancer and low genetic African ancestry, 3) Low risk of lung cancer and high genetic African ancestry, or 4) Low risk of lung cancer and low genetic African ancestry. After being given this hypothetical information, participants will complete brief questionnaires assessing perceived risk of lung cancer, worry about cancer, psychological distress, and motivation to quit smoking.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: HRHA
High Risk, High Ancestry
participants will be asked to consider a hypothetical scenario in which genetic test results reveal that: 1) they carry genotypes that place African American smokers at a particularly high (~50%-80%) risk for the development of lung cancer, and 2) their genetic profile reflects a particularly high concordance with African heritage (~90%).
Experimental: LRLA
Low Risk, Low Ancestry
participants will be asked to consider a scenario in which genetic test results reveal that: 1) they are at normal (~7%-10%) risk for the development of lung cancer, and 2) their genetic profile reflects a particularly low concordance with African heritage (~10%).
Experimental: HRLA
High Risk, Low Ancestry
participants will receive "High Risk, Low Ancestry (HRLA)" hypothetical
Experimental: LRHA
Low Risk, High Ancestry
participants will receive "Low Risk, High Ancestry (HRLA)" hypothetical

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Motivation to Quit Smoking
Time Frame: 1 minute after intervention
use self report 7 item (condition options) MTSS (Motivation to Stop Smoking) Scale with yes/no option to determine the quitting intention condition; range of scale : 1-7, with higher score means higher motivation to quit smoking
1 minute after intervention
