Summary

College smokers are interested in genetic testing for lung cancer susceptibility. This genetic risk information could motivate them to quit smoking, especially those with higher reward sensitivity.

Area of Science:

  • Behavioral Science
  • Genetics
  • Public Health

Background:

  • College student smoking rates have risen, necessitating novel cessation strategies.
  • Genetic susceptibility testing for lung cancer is a potential intervention.
  • Understanding psychological factors influencing interest in genetic testing is crucial.

Purpose of the Study:

  • To assess college smokers' interest in genetic testing for lung cancer risk.
  • To investigate the influence of personality traits (behavioral inhibition system, behavioral activation system) on responses to genetic risk feedback.
  • To determine if genetic risk information motivates smoking cessation behavior.

Main Methods:

  • Focus group discussions with sixteen smokers.
  • Survey of 186 undergraduate smokers measuring personality, risk perception, affect, and behavioral intentions.

  • Presentation of hypothetical high and low genetic risk feedback scenarios.

    • Main Results:

    • Smokers showed high interest in genetic testing.
    • Higher reward sensitivity correlated with greater interest in genetic testing.
    • Genetic risk feedback motivated smoking cessation attempts, particularly in reward-sensitive individuals.
    • Threat-sensitive smokers experienced greater negative affect from risk feedback.

    Conclusions:

    • Genetic biomarker feedback can motivate college student smokers to quit.
    • The effectiveness of genetic risk feedback is enhanced in individuals with high reward sensitivity.
    • Personality traits play a significant role in how smokers respond to genetic susceptibility information.
