Trial Outcomes & Findings for DECIDE: Developing Tools for Lung Cancer Screening Discussion Improvement (NCT NCT03891602)

Last Updated: 2024-08-23

Results Overview

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.

Baseline Characteristics

Clinicians who participated in the study were only asked for their age as a categorical variable as a result we cannot provide mean and standard deviation.
