CONCLUSIONS•HIGH RATES OF ASSAULT AND SEXUAL COERCION IN ALL COUNTRIES

• THE INJURY DATA SHOWS THAT MANY ASSAULTS ARE NOT TRIVIAL

•RATES OF PERPETRATION BY WOMEN AND MEN ARE SIMILAR, EXCEPT MEN CAUSE MORE INJURY

• MORE MEN PHYSICALLY FORCE SEX • RESULTS ARE CONSISTENT WITH OTHER STUDIES OF STUDENTS

• CULTURAL DIFFERENCES ARE PRESENT BUT NOT USUALLY VERY LARGE

RISK FACTORS FOR PSYSYCHOLOGICAL AGGRESSION

(VERBAL ATTACKS)

* RISK FACTORS ARE SIMILAR TO RISK FACTORS FOR PHYSICAL ASSAULT

* PROBABLY BECAUSE PSYCHOLGICAL AND PHYSICAL ATTACKS ARE HIGHLY

CONCLUSIONS•VIOLENCE AGAINST DATING PARTNERS HAS MANY “CAUSES” (“RISK FACTORS”)

•THE “CAUSES” OF VIOLENCE AGAINST PARTNERS ARE SIMILAR FOR MEN AND WOMEN

•EACH ADDITONAL RISK FACTOR INCREASE THE PROBABILITY OF VIOLENCE, BUT NONE GUARANTEE IT

•MOST OF THE RISK FACTORS ARE THINGS THAT CAN BE CHANGED

STRENGTHS OF THE IDV STUDY WELL-VALIDATED INSTRUMENT TO MEASURE

INTIMATE PARTNER VIOLENCE – THE CONFLICT TACTICS SCALES OR CTS. USED IN OVER 40 COUNTRIES WITH RESPONDENTS OF ALL SOCIOECONOMIC LEVELS, INCLUDING LOW EDUCATION RURAL AND URBAN POPULATIONS AND UNIVERSITY STUDENTS.

UNUSUALLY WIDE RANGE OF RISK FACTORS. THE

PERSONAL AND RELATIONSHIPS PROFILE OR PRP MEASURE 22 VARIABLES ASSOCIATED WITH PARTNER VIOLENCE (SEE APPENDIX 1)

PROCEDURES FIELD TESTED WITH MORE THAN 1,000

STUDENTS AT THREE DIFFERENT UNIVERSITIES IN THE USA AND IN CIUDAD JUAREZ IN MEXICO.

30 NATIONS PROVIDES THE OPPORTUNITY TO

EXAMINE THE EFFECT OF SOCIO-CULTURAL DIFFERENCES ON RISK FACTORS FOR DATING-VIOLENCE, INCLUDING SITES IN ALL MAJOR WORLD REGIONS.
