Awarded Research Grant to Prevent Violence and Violence-Related Injury
This project will use psychological profiles described by Holtzworth-Munroe & Stuart to identify batterer typologies in a population-based, cross-sectional study of partner violence (PV) perpetration.The three subtypes that will be employed (GVA, BD, and RO) have all been described. All participants will be asked about their violence perpetration, victimization, and their psychological profile. These data will be used to assess batterer subtypes and grouped as (a) current IPV perpetrators by batterer subtype, and (b) those with psychological profile of a batterer yet do not report physical PV (labeled high-risk non-perpetrators). Identifying the last group will allow for applying batterer typologies that may have important implications for prevention research. The investigators will explore protective factors for PV among this high-risk, non-perpetrator group.
Researchers will estimate the prevalence of and risk factors for both PV perpetration by batterer subtypes and high-risk, non-perpetration among 2000 students sampled from a large community college system in Houston, Texas. Measures of distal and proximal risk factors based on a theoretical model will be used to guide the assessment of correlates of both perpetrator and high-risk, and non-perpetrators by psychological batterer subtypes over three levels of influence (individual, family, and ethnic community). Point estimates and confidence intervals for PV typologies and perpetration will be estimated by gender. Multinomial logistic regression will be used to assess risk factors (e.g., childhood abuse and witnessing IPV, substance abuse, affect) for the three PV typologies by level of influence. To determine whether the novel, high-risk, non-perpetrator group is at increased risk of using force against a partner, a short-term (eight month) cohort study will be conducted to prospectively estimate PV risk among those not reporting perpetration in the cross-sectional interview by psychological profile. All respondents scoring as high-risk, having the psychological profile consistent with a battering subtype, yet not perpetrating PV will be included. A similar number of low-risk (no batterer psychological profile and non-perpetrators) will also be included as unexposed. Cox proportional hazards modeling will be used to estimate time to first use of physical force by psychological profile. Project outcomes will lead to more effective strategies for preventing partner violence.
