Purpose: Oftentimes, vulnerable populations are harder to reach through the media, particularly as technology advances. The Texting for Public Health Toolkit aims to change this by teaching public health agencies how to adopt this technology to communicate important, personal messages to numerous people. Tool Description: The Texting for Public Health Toolkit is an online tool that provides a tutorial to teach users how to create, market, and implement text messaging programs to improve emergency communications and other public health communications efforts. It does so by teaching the following learning objectives: - Explaining how text messaging can be a valuable communications strategy in public health practice - Planning a public health text message program - Identifying types of text message users - Marketing a public health texting program - Crafting text messages for a public health audience - Listing legal and security threats to a public health text message program - Describing the methods for sending text messages and how the technology works Who should use it?: Users of the tool should include members of the public health workforce, including staff from finance, information technology, management, and program delivery staff. Benefits: While SMS Text messaging is familiar to most of the US adult population, systematic adoption by health departments to use in emergency communications, health promotion, disease management, surveillance, medicine adherence or community development is limited. The Texting for Public Health Toolkit helps combat this by aiding in the implementation of mass texting systems.
