About this trial

The long-term objective is to improve lung cancer screening uptake among screening-eligible Black adults and thereby reduce the population burden of late-stage diagnosis and mortality. The short-term objective of this study is to rigorously test the effectiveness, mechanisms, and implementation readiness of Witness Project® Lung.

Treatments tested in this trial

Witness Project Lung
Behavioral
The Witness Lung Lung program is led by the Witness Role Model (WRM) using visual (i.e., geographically specific slide presentation with New Jersey (NJ) or New York (NY) lung screening resources), audio and video (i.e., short testimonials), and text (i.e., geographically-tailored take-home hand-out) components. At the end of the program, participants will be asked if they would like the Community Health Worker (CHW) to follow-up with them via their preferred method of contact to navigate them to screening. The CHW will also be available to meet with participants after the program to answer additional questions. Witness Project® Lung is a 60-minute program.
General Educational Program
Behavioral
The educational program consists of a didactic presentation about all screen-detectable cancers (breast, cervical, colorectal, lung, prostate) and their screening test(s) including eligibility criteria, guidelines, and how to get screened followed by a question-and-answer session. At the end, participants will be asked if they would like the CHW to follow-up with them to navigate them to screening options. The CHW will also be available to meet with participants after the program

Secondary outcomes

1

Stage of Adoption for Decision-Making About Lung Screening

Stage of Adoption for Decision-Making About Lung Screening will be assessed with an algorithm of questions used in the investigator's prior studies assessing the 7 stages (unaware, aware but unengaged, undecided, decided not to act, decided to act, action, and maintenance). This will allow us to assess intent if someone has "decided to act".

Stage of Adoption for Decision-Making About Lung Screening

Stage of Adoption for Decision-Making About Lung Screening will be assessed with an algorithm of questions used in the investigator's prior studies assessing the 7 stages (unaware, aware but unengaged, undecided, decided not to act, decided to act, action, and maintenance). This will allow us to assess intent if someone has "decided to act".

Time frame

Up to 24 hours post-intervention

Stage of Adoption for Decision-Making About Lung Screening

Stage of Adoption for Decision-Making About Lung Screening will be assessed with an algorithm of questions used in the investigator's prior studies assessing the 7 stages (unaware, aware but unengaged, undecided, decided not to act, decided to act, action, and maintenance). This will allow us to assess intent if someone has "decided to act".

Time frame

At six-months post-intervention

4

Medical Mistrust

Medical Mistrust will be measured using the psychometrically validated 5-item scale with items ranging from 5 (low mistrust) to 25 (high mistrust). This measure assesses constructs related to mistrust of the medical system including suspicion, discrimination, and lack of support. Reliability and validity have been well established with Cronbach's alpha of 0.87-0.88.
