Before and After Results for Knowledge, Decisional Conflict Scale, and Concordance (n=60)
| Before | After | |
|---|---|---|
| Mean (SD) | ||

| 2. Possible benefits of lung cancer screening [3] | 1.95 (0.77) | 2.70 (0.56) |
| 3. Possible harms of lung cancer screening [3] | 1.20 (0.99) | 2.23 (1.00) |
| 4. Which of the individuals would be eligible for screening based on the age, given that they all meet the smoking status and pack-year criteria? [1] | 0.52 (0.21) | 0.75 (0.25) |
| 5. What percentage of lumps found on your lung by the CT screening is NOT going to be cancer?b [1] | 0.08 (0.28) | 0.58 (0.50) |
| Decisional Conflict Scale (overall)c | 46.33 (29.69) | 15.08 (25.78) |
| Uncertainty subscale | 55 (40.07) | 18.33 (34.71) |

Note: Boldface indicates statistical significance (p<0.001).
The overall maximum score for the knowledge section is 14. Each specific question’s maximum score is specified in square parentheses.
The figures presented for question 5 are the proportion of participants that answered correctly as there was only one correct answer.
Lower scores in the Decisional Conflict Scale signify less decisional conflict. A score of lower than 25 is associated with implementing a decision. The overall score is the average of the subscales’ scores.
Participants who preferred to get screened and were also eligible for screening based on U.S. Preventive Services Task Force criteria were deemed “concordant,” as were participants not eligible for screening who preferred not to get screened. The figures reported are based on 59 responses, and represent the frequency and proportion of those who were concordant.
