This online randomized controlled trial seeks to determine if inclusion of incidental findings information in a lung cancer screening decision aid affects screening intent among screening-eligible individuals. Participants will view either a decision aid with incidental findings information or without and indicate their intent to pursue lung cancer screening. Hypothesis: Inclusion of incidental findings in a decision aid will decrease intent to screen among participants.

Percentage of individuals who plan to pursue lung cancer screening
This will be assessed by a survey item where participants indicate their response to a statement of whether they plan to pursue lung cancer screening, with answer choices being strongly agree, agree, disagree and strongly disagree. Comparison between the intervention and control groups will be made.
Time frame: Day 1
Mean score on scale of lung cancer screening knowledge
Lung cancer screening knowledge tested by 6 multiple choice questions on facts of the benefit and harms of screening. The questions will be answered before and after participants watch a lung cancer screening decision aid. Scores will be determined by the number of correct answers for questions.
Time frame: Day 1
Mean rating of benefit and harms of screening
Participants will rate (Likert 1-5 scale with 1 being less important and 5 being more important) 6 lung cancer screening benefits and harms on importance to them.
Time frame: Day 1
Percentage of Time Lung Cancer Screening Benefit and Harms are ranked first and last
Participants will rank six lung cancer screening benefits and harms.
Time frame: Day 1
Mean ranking of benefit and harms of screening
Participants will rank six lung cancer screening benefits and harms.
Time frame: Day 1
Percentage of time each lung cancer screening harm is ranked highest of the five potential harms
Participants will rank six lung cancer screening benefits and harms.
Time frame: Day 1
Mean ranking of incidental findings attribute
Participants will rank six lung cancer screening benefits and harms, including one on incidental findings. Comparison of mean ranking will be made between the intervention and control groups.
