Primary Outcome Measures

Name	Time	Method
Key Components of Shared Decision Making Process That Predict Patient-perceived Lung Cancer Screening Decision Quality	at baseline (study enrollment)	Decisional Quality was measured using the multidimensional Decisional Conflict Scale, a 16-item Likert-response scale that was modified by the investigators for the lung cancer screening context. The total score ranging from 0 to 64. This total score is commonly transformed into a standardized score that falls within a 0 to 100 range. Decisional quality measured on this numeric scale from which lower scores represent lower decisional conflict and, therefore, higher decisional quality. Scores below 25 have been associated with low decisional conflict.
