Gender differences in partner violence in a birth cohort of 21-year-olds: Bridging the gap between clinical and epidemiological approaches.

This study describes partner violence in a representative sample of young adults. Physical violence perpetration was reported by 37.2% of women and 21.8% of men. Correlates of involvement in severe physical violence differed by gender. Severe physical violence was more strongly associated with unemployment, low educational attainment, few social support resources, polydrug use, antisocial personality disorder symptoms, depression symptoms, and violence toward strangers for men than for women. Women who were victims of severe physical violence were more likely than men who were victims to experience symptoms of anxiety. The findings converge with community studies showing that more women than men are physically violent toward a partner and with clinical studies highlighting violence perpetrated against women by men with deviant characteristics.

Psychiatric disorder in a birth cohort of young adults: Prevalence, comorbidity, clinical significance, and new case incidence from ages 11–21.

Mental health data were gathered at ages 11, 13, 15, 18, and 21 in an epidemiological sample using standardized diagnostic assessments. Prevalence of Diagnostic and Statistical Manual of Mental Disorders-III-Revised (DSM-III-R) mental disorders increased longitudinally from late childhood (18%) through mid- (22%) to late-adolescence (41%) and young adulthood (40%). Nearly half of age-21 cases had comorbid diagnoses; and comorbidity was associated with severity of impairment. The incidence of cases with adult onset was only 10.6%: 73.8% of adults diagnosed at age 21 had a developmental history of mental disorder. Relative to new cases, those with developmental histories were more severely impaired and more likely to have comorbid diagnoses. The high prevalence rate and significant impairment associated with a diagnosis of mental disorder suggests that treatment resources need to target the young adult sector of the population. The low new-case incidence in young adulthood, however, suggests that primary prevention and etiological research efforts need to target children and adolescents.

Developmental antecedents of partner abuse: A prospective-longitudinal study.

Prospective measures of risk factors for partner abuse were obtained from a large birth cohort in 4 domains: socioeconomic resources, family relations, educational achievements, and problem behaviors. Partner abuse outcomes were measured at age 21. Results showed that antecedents of abuse included risk factors from all 4 domains. Risk factors were similar for men and women. Some age 3 antecedents were significant, but the strongest correlations were from age 15. In multivariate analyses, the most consistent predictor was the presence of early problem behaviors. In a cross-validation test, abuse was moderately predictable by the same antecedents, whether the outcome measure was self-report or reports from partners of sample members. Findings suggest that theories of partner abuse should account for developmental influences from multiple life domains and that primary prevention of partner abuse should begin in adolescence.

Do partners agree about abuse in their relationship?: A psychometric evaluation of interpartner agreement.

This study tested whether partners can be relied on to provide congruent reports about abuse in their relationship. The authors examined whether interpartner agreement (IA) varies as a function of whether the perpetrator is the man or the woman, and by whether the abusive behavior being reported is physical or psychological. Guided by psychometric test theory, the authors examined whether weak IA about specific behaviors can be improved by aggregating behavior items into scales and by controlling for random measurement error. A representative sample of 360 young couples was studied. IA did not vary with the perpetrator's gender or with the nature of the abusive behaviors, but victims (both men and women) reported somewhat more abuse than did their perpetrators. IA about specific abusive behaviors was only poor to fair, but it became very good when items were aggregated into scales and even better when measurement errors were removed form the reports. The findings suggest that reports of abuse can be aggregated to form internally consistent scales that show strong IA, thereby fulfilling criteria for reliability. Moreover, under research conditions that guarantee confidentiality, either abuser reports or victim reports are suitable methods for use in research on partner abuse.
