 TailorTool is a software tool created by the UNC CHAI Communication for Health Applications and Interventions Core that enables the creation and delivery of tailored communications in a dynamically generated pdf newsletter format. The tool generates intervention material such as individual feedback on targeted behaviors and variables such as relevant demographics, psychosocial factors, and barriers. Templates of various page lay-out possibilities allow individualization of the look of the newsletters. Messages are drawn from a message library of text files of varying lengths depending on the needs of the research study. Graphics can be imported into the various template pages. Newsletters can vary in length and can be personalized with names of participants. Following completion of an online survey the newsletters are created in a pdf format for reading, saving, andor printing by the participant. Each subsequent newsletter can be available immediately or timed for release to fit the timeline of the intervention.
