The high prevalence of intimate partner violence (IPV) (25%-54%) over an adult women's lifetime, and its profound health impact such as injury and sometimes chronic conditions or death underscores the importance of considering its risk and protective factors at multiple levels of influence. This study will investigate both individual and neighborhood factors related to IPV risk and these factors longitudinally, given that IPV is context-specific, arising in part from the interaction between neighborhood and individual level characteristics over time.

Social disorganization theory will be used to investigate the influence of neighborhood-level socioeconomic advantage, residential stability, and family stability; individual level factors associated with victims and perpetrators (e.g., race/ethnicity, substance abuse history, prior year IPV history); and arrest status on risk of any IPV recurrence and chronicity (number of recurrences), type (physical vs. non-physical) and severity (involving weapons and/or victim injury) over a one-year period. Data on IPV recurrence will be derived from an existing cohort of 6788 Seattle couples followed for one year after an incident of police-reported IPV. Generalized estimating equations will be used to test the hypothesis that residences in neighborhoods characterized by high per capita income and education, low unemployment, and residential mobility and family disruption protects against any IPV recurrence, frequency of recurrence, and recurrence of physical and severe IPV within the original victim-perpetrator dyad, independent of individual level characteristics describing victims and perpetrators. This is the largest longitudinal study to evaluate neighborhood and individual factors associated with IPV chronicity, type and severity. Researchers can better target specific populations for interventions and elucidate community- level lPV prevention efforts with greater knowledge of how specific neighborhood level factors contribute to IPV risk. The investigator will work with the King County and Washington State Departments of Health to translate study findings into programs that consider neighborhood and individual factors for IPV risk and that can be rigorously evaluated.
