C-Raven, a Virtual Tobacco Cessation Intervention in the Community
brief summary
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.
detailed 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. At the end of three 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 iterative improvements to the existing intervention, aligned with user-experience design procedures.
Participants (N=30) will be recruited through flyers posted in and around the housing units and distributed to tenants by housing unit staff. Flyers will describe the study and contain a study phone number to call. Information may also be distributed by study staff during non-study-related health and wellness activities conducted at the sites. At initial contact, a study staff member will discuss the study purpose and determine eligibility. If eligible, the staff member will proceed to discuss requirements, review risks and benefits, and obtain informed consent from interested participants.
Consent process: After confirming eligibility with screening questions via phone, potential participants will be offered the option of reviewing the study information and consent form over a Zoom video conference. Regardless of whether the participants choose to review this information in advance, all potential participants will complete the consent process and sign the consent form at the beginning of the first in-person visit, which will be conducted on-site at the participants housing community.
Randomization: Following consent, participants will be randomized to the intervention group or a control group. The control group will not receive any intervention during the first 6 months of the study, but at the end of 6 months will receive the full computer intervention and abbreviated CHW support to ensure access to treatment for all participants.
Baseline Assessment: This will occur on the same day as the in-person portion of the consent process. Initial evaluation will comprise a number of questionnaires/assessments, including demographics, a clinical history, a tobacco use history, and a number of tobacco-related measures. Assessments will be self-administered via tablet computer.
