One way to reduce consumption levels is to provide a brief in-person intervention in primary care and various other community settings (see Chapter 6). However, there are several barriers to implementing brief interventions in practice, and thus brief e-health interventions may be an effective alternative when it is not feasible to use a brief intervention. Indeed, as overviewed in this chapter, e-health interventions have a small but significant effect on alcohol use, may have similar short-term benefits to in-person interventions, and are very cost effective.
