Assessing Usability of mHealth Autism Screeners in the Medically Underserved

点击翻译按钮获取中文摘要

PROJECT SUMMARY The NIH and the private sector have invested millions of dollars into development of mobile technology- based (mHealth) autism screening tools, with the hope that advanced technologies will improve early identification of Autism Spectrum Disorder [ASD]. However, no research to date has assessed how mobile device-based ASD screening will address the problem of racial, ethnic, language, and income disparities in ASD identification. In addition, no current efforts explicitly assess what key mHealth ASD screener adaptations are needed for mHealth autism screeners to be successfully used by minority and low-income families and the professionals who interact with them. In this proposal, we will examine existing mHealth ASD screeners for overall quality and adaptability to ASD health disparities populations, by comparing them to established mHealth standards. We will then perform user testing of key tools with a sample of racial/ethnic minority and low-income families and health and educational providers. We will interview parents, providers, and mHealth ASD screener developers, to understand the challenges of creating and using mHealth ASD screeners in health disparities populations. Finally, we will use the results of this research, and the guidance of a multi- disciplinary expert panel, to develop a set of guidelines for mHealth autism screener usability in ASD disparities populations. We will disseminate these guidelines throughout the autism research and informatics communities. This research will ensure that the next generation of ASD screening tools effectively reduces disparities in ASD identification.
