A Sociolinguistic-enabled Web Application to Develop Precision Health Intervention for African Americans

University of Florida·interventional·Posted Jan 12, 2021·Updated Apr 18, 2025

In Brief

A clinical study evaluating High Dialectal, Low Dialectal, and 2 other interventions for Colorectal Cancer. Completed, enrolled 751 participants across 1 site.

Detailed Summary

This pilot study will explore the preliminary efficacy of a colorectal cancer (CRC) screening intervention delivered by Virtual Human Agents (VHAs). Seven hundred fifty participants aged 45 to 75 will be recruited through Qualtrics panels. The study examines how different levels of dialectal linguistic features willingness to be screened for colorectal cancer. Participants will be randomly assigned to interact with one of four VHA conditions: a VHA using non-dialectal linguistic features, a VHA with a low level of dialectal linguistic features integrated, a VHA with a high level of dialectal linguistic features integrated, or a text-only control condition. Following the interaction, participants will complete survey measures to assess perceived willingness to be screened.

Interventions

High Dialectalbehavioral

A virtual health assistant that will consist of an interactive computer-generated doctor with voice that used high dialectal variation that will guide participants through the interaction.

Low Dialectalbehavioral

A virtual health assistant that will consist of an interactive computer-generated doctor with voice that used low dialectal variation that will guide participants through the interaction.

Non-Dialectalbehavioral

A virtual health assistant that will consist of an interactive computer-generated doctor with voice that used no dialectal variation that will guide participants through the interaction.

Text-onlybehavioral

A virtual health assistant that will consist of photos of the computer-generated doctor with text that will guide participants through the interaction. No voice will accompany the photos or text.
