Enhanced Nurse Home Visitation to Prevent Intimate Partner Violence

Study Summary

An Enhanced Nurse Home Visitation Program To Prevent Intimate Partner Violence; This randomized trial of an intervention to assess and prevent intimate partner violence during pregnancy and the post-partum builds upon the David Olds model of nurse home visitation (Nurse Family Partnership or NFP) for high risk mothers and infants that has shown to be effective in multiple settings in preventing child abuse and enhancing maternal and child health and psychosocial outcomes. However, prior research has shown that the NFP intervention is not as effective in homes where there is intimate partner violence (IPV). Although the NFP by itself has reduced IPV in one setting, it has not in another. The proposed study will test the efficacy of an enhanced NFP intervention, the ECI or Enhanced Choice Intervention among women referred to an existing NFP program in Portland, Oregon. The ECI is based on a choice or empowerment model whereby women can choose among interventions related to her goal for her current intimate relationship. If IPV or emotional abuse or controlling behaviors are assessed, the intervention is based on two interventions shown to be effective in assessing for and reducing repeat IPV (the Sullivan Advocacy Intervention and the McFarlane and Parker brochure driven intervention). For women desiring to enhance marital quality, the Markman and Stanley PREP model that has been shown to enhance relationship quality will be offered. The PREP model also has some preliminary evidence of preventing IPV. For women with other risk factors for IPV in their own or their partners' history (e.g. exposure to parental IPV, child abuse, substance abuse), community resource linkage (beyond referral) strategies as with the NFP model will be used to obtain community resources to address these risk factors. 250 women referred to the Multnomah County Health Department will be randomized to the experimental (NFP plus ECI) or control condition (NFP) and visited according to the regular

Primary Outcome

Women were given several different standardized measures regarding the amount of physical violence they might be experiencing including the Strauss Conflict Tactic Scale (CTS2r), Relationship Danger Assessment (RDA), and Proximal Antecedents of Violent Episodes Scale (PAVE).

Interventions

• BEHAVIORAL Enhanced NFP (NFP+)
• BEHAVIORAL NFP as usual
