Hands-on Killing of Intimate Partners as a Function of Sex and Relationship Status/State

Guided by evolutionary psychology and a situational perspective on violence, we generated three hypotheses to investigate whether the percentage of intimate partner homicides by beating, a hands-on homicide method, varies with the victim-offender relationship. We tested these hypotheses with a national database that includes incident-level information on over 50,000 intimate partner homicides. Results indicate that: (1) men are more likely than women to kill a partner by beating, and (2) men are more likely to kill their partners by beating when the relationship is dating or non-marital cohabiting (versus legal marriage). We argue that the lack of commitment in these non-marital relationships may produce greater jealousy in men, driving the perpetrator to kill his victim in a more violent manner (i.e., beating), relative to men who kill their wives.     

Filicide-suicide in Chicago, 1870-1930

Filicide (the killing of a child by a parent) followed by the offender's suicide is a tragic but, fortunately, rare event. The contexts and circumstances surrounding filicide-suicide may provide insight into parental psychology. The authors test several hypotheses about filicide-suicide using a database including incident-level information on 11,018 Chicago homicides during 1870-1930. The results provide some support for the hypothesis of differential risk of suicide following filicide by genetic parents and stepparents and replicate previous research indicating that filicides with multiple victims are more likely to end in the offender's suicide than are filicides with a single victim; parents are more likely to commit suicide following the filicide of an older child than of a younger child; and older parents, relative to younger parents, are more likely to commit suicide following filicide. The discussion situates these results within the existing literature and highlights important directions for future research.     

Substance Use and Intimate Violence Among Incarcerated Males

The purpose of this study was to examine substance use patterns among a sample of incarcerated males who report engaging in levels of intimate violence, as well as identifying similarities and differences in demographic, economic status, mental health, criminal justice involvement, relationships, and treatment factors for three groups of incarcerated males - those who report perpetrating low intimate violence, those who report perpetrating moderate intimate violence, and those who report perpetrating extreme intimate violence the year preceding their current incarceration. Findings indicated that low intimate violence group's perpetration consisted almost exclusively of emotional abuse. Moderately intimate violent males and extremely intimate violent males, however, report not only high rates of emotional abuse but physical abuse as well. The distinction between moderate and extremely violent groups was substantial. Findings also indicated that perpetrators at different levels of violence in this study did not vary significantly in age, employment history, marital status, or race. However, the three groups showed significant differences in three main areas: (1) cocaine and alcohol use patterns, (2) stranger violence perpetration and victimization experiences, and (3) emotional discomfort. Implications for substance abuse and mental health treatment interventions and for future research are discussed.     

Men’s Partner-Directed Insults and Sexual Coercion in Intimate Relationships

Women who have been sexually coerced by an intimate partner experience many negative health consequences. Recent research has focused on predicting this sexual coercion. In two studies, we investigated the relationship between men’s use of partner-directed insults and sexually coercive behaviors in the context of intimate relationships. Study 1 secured self-reports from 247 men on the Partner-Directed Insults Scale and the Sexual Coercion in Intimate Relationships Scale. Study 2 obtained partner-reports from 378 women on the same measures. Across both studies, results indicate that men’s use of sexually coercive behaviors can be statistically predicted by the frequency and content of the insults that men direct at their intimate partner. Insults derogating a partner’s value as a person and accusing a partner of sexual infidelity were most useful in predicting sexual coercion. The discussion notes limitations of the current research and highlights directions for future research.
