Abstract: Objective To survey and promote individual-response behavior and first aid ability among college students when encountering violent terrorist attacks,and provide references for the effective intervention.Methods A total of 1 500 college students were selected by using the random cluster method.A questionnaire involving the response to violent terrorist attack behavior and involving general knowledge of first aid was used to assess their preparedness behavior and their first aid ability.Then,they learn how to response to violent and how to give first aid through multimedia and demonstrating.One year later,they were questioned and examined again.Results Before and after intervention study,the mean score of the individual preparedness behavior were (13.11 ± 5.79) and (27.02 ± 13.71) respectively,while the information on seeking behaviors were (4.08 ± 1.85) and (6.35±2.77) respectively,the avoidance behavior were (5.66±2.49) and (10.31± 5.18) respectively,and the general knowledge of first aid were (41.83± 12.33) and (69.74±20.17) respectively.The differences were all significant (P<0.01).Before and after intervention study,sex,difference between urban and rural areas,regional difference all had no effect on the result(P>0.05).Conclusion Individual-response behavior and first aid ability among college students when encountering violent terrorist attacks weren't relatively ideal before intervention.Proper intervention made satisfactory effects,which still cannot meet our realistic need.Thus it is of practical significance to improve intervention methods.
