Social service professionals are more frequently identifying children who w
itness adult domestic violence as victims of that abuse. This article expan
ds common definitions of how children witness adult domestic violence. A to
tal of 31 research articles that met established quality criteria were incl
uded in this review. A variety of behavioral, emotional, and cognitive-func
tioning problems among children were found to be associated with exposure t
o domestic violence. Factors that appear to moderate the impact of witnessi
ng violence-such as whether the child was also abused, child gender and age
, and the time since last exposure to violence-were identified. Concerns ab
out research methodology used in this area of research and the application
of this knowledge also are raised.
