Contemplating Genetic Feedback Regarding Lung Cancer Susceptibility

  • Published:

Abstract

Background and Purpose

We examined three theoretical models (self-enhancement theory, consistency theory, and a combined model) for understanding how expectations and test result favorability influence smokers' desire for a retest following hypothetical genetic test results.

Method

College smokers (N = 128) read a brochure describing a biomarker for lung cancer (the GSTM1 gene) then reported whether they thought they had the gene (indicating lower lung cancer risk) or were missing the gene (indicating higher lung cancer risk). Participants then reported whether they would get retested if they received favorable GSTM1 results versus unfavorable GSTM1 results.

Results

Participants were most likely to want a retest, suggesting rejection of the results, if they expected favorable news yet received unfavorable news.

Conclusion

The findings supported the combined model such that smokers expressed greatest interest in a retest when they imagined genetic risk feedback that challenges both enhancement and consistency motives.
