C-Raven, a Virtual Tobacco Cessation Intervention in the Community
C-Raven: Pilot Randomized Controlled Trial (RCT) of an Avatar-delivered Computerized Intervention for Tobacco Cessation With Community Health Worker Linkage to Lung Cancer Screening in Baltimore City
Source: ClinicalTrials.gov · Last updated 2 Feb 2026
Brief summary (registry, in English)
In low-income housing units in Baltimore, the investigators propose to conduct a pilot two-arm hybrid type 1 effectiveness-implementation 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 public housing units (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. At the 3-month time point, the investigators will conduct interviews with a subset of pilot participants to collect qualitative data on intervention acceptability.
