Trial Outcomes & Findings for Incorporating Veterans' Preferences Into Lung Cancer Screening Decisions (NCT NCT02899754)

Last Updated: 2024-11-14

Results Overview

The Decisional Conflict Scale is a 16-item scale with a value that ranges 0 (low decisional conflict) to 100 (high decisional conflict. The scale includes five subscales in the domains of uncertainty ( 3 items), Informed (3 items), Value Clarity (3 items), Support ( 3 items), and Effective DM (4 items). Each item is scored from a 0 (strongly agree), 1 (agree), 2 (neither agree nor disagree), 3) (disagree) or 4 (strongly disagree). The total sore for the 16 items is calculated by a) summing scores, b) dividing by 16, c) multiplying by 25. Scores range from 0 (no decisional conflict) to 100 (extremely high decisional conflict). For each subscale the scores are obtained by a) summing scores, b) dividing by the number of items in the subscale, c) multiplying by 25. Scores are interpreted as range from 0(low decisional conflict) to 100 (high decisional conflict) in the respective domains.

Measure	Intervention Group Participants in this arm will use the lung cancer screening decision aid (LCSDecTool) Lung Cancer Screening Decision Tool: This will be a lung cancer screening decision support tool that is web based and provides patients with information about the potential benefits and harms associated with lung cancer screening and helps them to consider their personal values when making a decision about whether to initiate or continue with lung cancer screening.	Control Group Content that provides general information on disease prevention and health promotion unrelated to lung cancer. The information will be delivered on the same modality and take a similar amount of time to administer. Control Intervention: This will be a health message regarding prevention and healthy behavior that is not related to lung cancer screening but delivered in a similar modality and taking approximately the same amount of time as the LCSDecTool.
