Incidental Findings
Brief summary
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.
Interventions
BEHAVIORALLung Cancer Screening Decision Aid with Incidental Findings Information
The intervention consists of a previously tested and developed brief lung cancer screening video decision aid with the addition of information on incidental findings for lung cancer screening.
BEHAVIORALLung Cancer Screening Decision Aid without Incidental Findings Information
The intervention consists of a previously tested and developed brief lung cancer screening video decision aid that does not include information on incidental findings.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of individuals who plan to pursue lung cancer screening | Day 1 | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Mean rating of benefit and harms of screening | Day 1 | 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. |
| Percentage of Time Lung Cancer Screening Benefit and Harms are ranked first and last | Day 1 | Participants will rank six lung cancer screening benefits and harms. |
| Mean score on scale of lung cancer screening knowledge | Day 1 | 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. |
| Percentage of time each lung cancer screening harm is ranked highest of the five potential harms | Day 1 | Participants will rank six lung cancer screening benefits and harms. |
| Mean ranking of incidental findings attribute | Day 1 | 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. |
| Mean ranking of benefit and harms of screening | Day 1 | Participants will rank six lung cancer screening benefits and harms. |
