Objective: To explore the cognitive and coping styles, and their relationship in domestic violence victims.Methods: 179 victims of domestic violence in two areas were recruited. Self-designed forms of general situations and perception of domestic violence, short version of Conflict Tactics Scale, questionnaire of subjective dependence on marriage,coping style questionnaire were used. Results: Economy was the main factor of victims' dependence on marriage(62.57%),followed by the emotional loneliness and parents displeasure(50.84%); About 40% of victims held cognitive biases, such as"Domestic shame should not be made public, fighting between intimate partners are very common, sometimes assault from partner is uncontrollable and then should be forgiven" and so on; coping styles were positively correlated with scores of subjective reliance on marriage and cognitive biases on domestic violence(t=0.239, P=0.000; t=0.148, P=0.014). Conclusion: The more victims subjectively depended on marriage, the more cognitive biases about domestic violence victims hold,and the more negative coping style the victims tend to adopt.
