OBJECTIVES: Estimates of intimate partner violence in the United States based on representative samples have relied on data from one person per household or limited numbers of indicators from both partners. The purpose of this study was to estimate nationwide rates of intimate partner violence with data from both couple members by using a standardized survey instrument, the Conflict Tactics Scale. METHODS: A multistage probability sampling design was used to conduct separate face-to-face interviews in respondents' homes with both members of 1635 representative couples living in the 48 contiguous states. RESULTS: Both partners' reports were used to estimate the following lower- and upper-bound rates: 5.21% and 13.61% for male-to-female partner violence, 6.22% and 18.21% for female-to-male partner violence, and 7.84% to 21.48% for any partner-to-partner violence. CONCLUSIONS: High rates of intimate partner violence in the United States corroborate previous claims that the amount of intimate partner violence is substantial.

Self-reports from 704 college students were content analyzed and used to develop the Marijuana Effect Expectancy Questionnaire and Cocaine Effect Expectancy Questionnaire. Responses were examined using exploratory and confirmatory principle components analysis. Six marijuana expectancies (34.6% of variance) were identified: (a) cognitive and behavioral impairment, (b) relaxation and tension reduction, (c) social and sexual facilitation, (d) perceptual and cognitive enhancement, (e) global negative effects, and (f) craving and physical effects. Five cocaine expectancies (32.5% of variance) consisted of (a) global positive effects, (b) global negative effects, (c) generalized arousal, (d) anxiety, and (e) relaxation and tension reduction. Drug effect expectancies distinguished between patterns of nonuse and varying degrees of use of these two drugs.

Healthcare facilities should continue to measure WPB in the work environment after policy implementation as well as eliminate negative behaviors through root-cause analysis to correct environmental factors associated with WPB.

The present study was designed to identify the impact of drinking problems, impulsivity, and a history of childhood physical abuse on both male-to-female (MFIPV) and female-to-male intimate partner violence (FMIPV). The data were collected in 1995 from a representative national sample of couples living in the contiguous 48 states. Using a multistage probability sampling design, face-to-face interviews were conducted in respondent' homes, privately with each member of 1, 635 couples. A complex path model building on earlier work was tested for African American, Hispanic, and White couples separately. Multiple-group path analysis demonstrated that impulsivity, alcohol problems, and childhood physical abuse were differentially associated with reports of MFIPV and FMIPV as a function of ethnicity. This study suggests that a history of being physically harmed by parental figures during childhood, impulsivity, and drinking problems are all risk factors for intimate partner violence in the general household population in the United States.

Alcohol-related problems among men and women and drug use among women, appear to be important correlates of male IPV severity among couples in the general population. These findings can aid in IPV screening efforts, the formulation of prevention strategies, and help inform batterer and victim treatment programs.
