Pilot study of a video intervention to reduce anxiety and promote preparedness for lung cancer screening

Lung cancer screening (LCS) with low dose computed tomography (LDCT) is associated with a 20% reduction in lung cancer mortality. Psychological burden is a potential harm associated with LCS, and is a major barrier to utilization. We aimed to examine the feasibility and acceptability of a video intervention designed to reduce anxiety and promote psychological preparedness of LCS.

This is a two group, sequential enrollment pilot study of a video intervention that integrates information on screen criteria, procedures, benefits and harms, and follow-up plan. Participants were enrolled 1-2 weeks prior to baseline LDCT, and the intervention was administered in one in-person session on the day of LDCT. Outcomes were assessed at baseline (pre-screen), immediately after LDCT, and at 1 week, 3 months, and 7 months post-screen. Outcome measures included the SF-12 (HRQOL), STAI (anxiety), psychosocial consequences of LCS (COS-LC), risk perceptions for lung cancer, and a satisfaction tool. The student's t-test was used for exploratory evaluations on change from baseline scores both within and between groups.

Sixteen participants (8 intervention, 8 controls) enrolled and completed the study (61.5% retention). Participants in the control group reported a significantly increased sense of dejection at 1-month and 7-months post-screen as measured by the COS-LC (p = 0.01). Participants were highly satisfied with the intervention.

A video intervention that promoted psychological preparedness for LCS was feasible to implement as part of an LCS program and highly accepted by participants.
