RCT of HeartBot in Women

Summary

The goal of this clinical trial is to find out whether an app-based program called HeartBot II, which uses an artificial intelligence (AI) chatbot, can help improve women's awareness and knowledge of heart attacks in women.

This is an online study with about 200 women taking part. Participants will be randomly assigned (by chance) to one of two groups: an intervention group or a wait-list control group.

Participants in the intervention group will begin using the HeartBot II program right away. Participants in the wait-list control group will wait 12 weeks before starting the HeartBot II program. The HeartBot II program includes four short modules. In each module, participants will interact with a chatbot and spend about 10 to 15 minutes completing the content.

Participants will be asked to complete an online screening and baseline survey at the start of the study, as well as two follow-up surveys at 12 weeks and 24 weeks.

Interventions

OTHER

HeartBot II Program

Participants assigned to the intervention group will receive the HeartBot II intervention during the first 12 weeks. Participants in the intervention group will download the HeartBot II application on their smartphone, register their account with the access code provided by the research team, and will be asked to start Module 1 immediately after randomization. The HeartBot II application consists of 4 module and each module is scheduled approximately 3 weeks apart. It will take about 13 minutes to complete each modules.

OTHER

Waitlist Control

The waitlist control group will not receive the HeartBot II intervention during the initial 12-week period, but will receive a text message once week for 12 weeks for attention control. These text messages do not include any educational content related to heart attack or heart health and are limited to neutral study reminders and general self-report prompts. Following completion survey at week 12, participants in the waitlist control group will initiate the HeartBot II program, delivered identically to the intervention group.
