Intimate partner violence (IPV) is generally considered to include violence/abuse and coercive control (CC), a pattern of control, threats, coercion, and surveillance by abusive partners. While survivors report that CC is as traumatic as violence/abuse, CC is not illegal in the U.S.; furthermore, there is no consensus on how best to measure CC. The 14-item coercive control subscale of the Mediator’s Assessment of Safety Issues and Concerns (MASIC) is one possibility. A factor analysis of the entire MASIC suggested that CC questions form one factor, but this structure has not been corroborated and does not conform to CC theory. Another study is warranted. Therefore, the purpose of this study is to conduct an exploratory factor analysis (EFA) of the MASIC CC questions.
