Brief Summary
The Accelerating Colorectal Cancer Screening and follow-up through Implementation Science (ACCSIS) Program addresses major regional CRC screening disparities among AI in Oklahoma. The investigators are engaged in a participatory and collaborative effort with Tribal Nations, Area Indian Health Boards, and Indian Health Service (IHS) healthcare facilities. The overall objective of this proposal is to leverage these relationships and examine the feasibility of co-developing and disseminating a v-TCHE as part of a multi-channel communication intervention. To achieve this objective, the investigators have partnered with IHS Clinton Service Unit, which serves members of the Cheyenne and Arapaho Tribes. The intervention will be disseminated across two channels: (1) Social Media (i.e., accessed via online study adverts) and (2) Clinic (i.e., direct messaging to patients via a study link in a SMS text). Across both channels, the investigators will examine reach of the intervention and its potential efficacy via a randomized controlled trial. Once participants click on the study link they will be randomized 1:1 to one of two intervention conditions: (1) watch a Narrative Testimonial Video of a real-life Tribal community health educator (control) or (2) an interaction with a v-TCHE. Participants will then complete a post-intervention survey, in which they can click to order a FIT kit afterwards.

Outcome Measures
Primary Outcomes (1)
Reach
The percentage of participants who successfully engage with the intervention (i.e., via click through rate) and compared across intervention channels (Social Media vs. Clinic). A GIS analysis will determine where reach was geographically greatest.
From enrollment to the end of the intervention at 30 days

Study Arms (2)
Narrative Testimonial Video of a Tribal Community Health Educator
ACTIVE COMPARATORThe narrative testimonial will provide a first-person recording of a real Tribal community health educator. In addition to the kernel information, the narrative video will employ culturally concordant storytelling about their personal experiences helping AI patients get screened and positive outcomes associated with early detection.
v-TCHE Interaction
ACTIVE COMPARATORParticipants can interact via a set of authored responses or speak freely to the vTCHE. The v-TCHE uses Google Speech-to-Text to convert participant speech into text and Google's DialogFlow logs participants' selections, utterances, and interactions with the vTCHE. The interaction will elicit individual preferences, address concerns about CRC, and empower decision-making while still promoting CRC screening.
