Reviews in this issue highlight how eHealth technologies are changing our thinking about public health surveillance and the collection of data for alcohol research (see the articles by Beckjord and by Freisthler) and beginning to transform clinical practice across the continuum of care (see the articles by Cronce, by Harris, and by Quanbeck). With such extensive access to computers, mobile devices, and the Internet in the United States (Duggan 2013), eHealth has the capacity for broad reach, including traditionally underserved populations (e.g., rural communities, racial/ethnic minority groups) (Gibbons et al. 2011; Marsch 2012). Internet- or computer-delivered education, screening, and intervention can offer a cost-effective means of reducing barriers to help-seeking through on-demand, round-the-clock access to information and services (Strecher 2007). The reviews in this issue, written by leaders in the field, discuss the implications of eHealth technologies for refining the measurement and monitoring of alcohol use, revising theories of behavioral change, and restructuring models of health care delivery.
