Abstract: Objective To investigate the factors associated with physical intimate partner violence (IPV)perpetration among men using ecological model.Methods A 1:1 case-control design was adopted and 132 men who perpetrated physicall acts of IPV were taken as the study group and 132 normal controls were matched in age and in the same neighborhood with the study group.All participants were assessed with brief Conflict Tactics Scale 2rd(CTS2)and Personality Diagnostic Questionnaire-4+(PDQ-4+).Results Ten predictive variables found to be significant by univariate analysis were men with low education(χ²=13.67,P=0.03),men with unstable job(χ²=10.70,P=0.01),witnessing mother beaten by father in childhood (χ²=7.02,P=0.03),experiencing neglect by father in childhood(χ²=9.34,P=0.01),partner's communication pattern(χ²=7.96,P=0.02),presence of extramarital affairs(χ²=12.11,P=0.01),neighbor's attitude toward perpetration(χ²=10.79,P=0.01),personality(χ²=11.00,P=0.00),behavior control(χ²=18.18,P=0.00),and economic control(χ²=61.88,P=0.00).Combined with professional interpretation and including individual's favorable attitude toward perpetration(χ²=7.45,P=0.06),the Results of matched pair logistic regression showed that the main risk factors contributing to male-perpetrated physical violence were men with unstable job(odds ratioOR=7.51;95% confidence intervalCI:1.51-37.23),experiencing neglect by father in childhood(OR=3.74;95% CI:1.59-8.79),individual's favorable attitude toward perpetration(OR=5.70;95%CI:1.50-21.10),and economic control(OR=10.64;95%CI:4.02-28.14).Conclusion Man with unstable job,experiencing neglect by father in chidhood,individual's favorable attitude toward perpetration,and economic control are major influencing factors for intimate partner violence.
