This review summarizes a growing number of methodological concerns emerging from research on child witnesses of intimate partner violence (IPV). A brief summary of various psychological, biological, and cognitive impairments associated with witnessing IPV is presented. Directions for future research in this area are explored with particular attention paid to experimental design. Advantages and disadvantages of retrospective, cross-sectional, and longitudinal designs are evaluated. Suggested improvements include the use of multiple informants, behavioral observations, and prospective, longitudinal assessment.
