C-Raven: Pilot RCT of an Avatar-delivered Computerized Intervention for Tobacco Cessation With Community Health Worker Linkage to Lung Cancer Screening in Baltimore City (FY26)
Johns Hopkins University
Summary
In a residency clinic in Baltimore, the investigators propose to conduct a pilot RCT comparing a) an avatar-delivered computerized intervention (CI) for tobacco cessation augmented with CHW support and navigation to lung cancer screening to b) a waitlist control. With a sample of participants from the residency clinic (N=30), the investigators will collect data on feasibility of recruitment, intervention engagement and completion, and short-term smoking cessation outcomes. Individuals will be assessed at baseline, 1 month, 3 months, and 6 months. The investigators will conduct interviews with a subset of pilot participants to collect qualitative data on intervention acceptability.
Description
The investigators will conduct a pilot randomized controlled trial of an avatar-delivered computerized intervention for tobacco cessation and CHW support to collect data on the feasibility of recruitment, intervention engagement and completion, and short-term smoking cessation outcomes. Individuals will be assessed at baseline, one month, three months, and six months. The investigators will conduct follow-up interviews with a subset of pilot participants to collect qualitative data on intervention acceptability. Based on the information collected in these efforts, the investigators will make i…
