BACKGROUND • IPV rates are highest among 16-24 year olds • No evidence of effectiveness of screening, nor of potential risks to young women • Lack of validated screen instruments for adolescents
Our Prior Research Anonymous A-CASI survey of 645 ethnically diverse women (15-23yr) found: • 46% of young women reported physical or sexual violence in current relationship • Did not mind being asked • Health provider was best person to ask • Most supported universal screening • Requested screen begin with positive questions • Equal proportion women reported participation
Randomized Trial of Three IPV Screens 3 Screen Types: • “Basic” • “Healthy Relationship” • “Mutual”
Study Goals Primary: • Physical violence by partner EVER in life and/or • Sexual violence by anyone EVER in life Secondary: • Current Physical violence and/or Sexual Violence (in past year) • Women’s Experience with screens • Provider’s Experience with screens
The “Basic” Screen(5 questions) In the Past Year:(Never, Seldom, Sometimes, Often, Always) • My partner is suspicious that I am unfaithful • My partner forced me to have sex when I didn’t want to. • My partner hit, slapped, or physically hurt me on purpose Ever in your lifetime:(Yes / No) • Have you ever been slapped, hit, or otherwise physically hurt by any partner? • Has anyone ever raped you or forced you into a sexual act?
The “Healthy Relationship” Screen(7 Questions) “Basic” Screen PLUS: • My partner respects me • My partner treats me well Responses: Never, Seldom, Sometimes, Often, Always
The “Mutual” Screen(8 questions) “Basic” Screen PLUS: in the past year • I am suspicious that my partner is unfaithful • I forced my partner to have sex when s/he didn’t want to • I hit, slapped, or physically hurt my partner on purpose Responses: Never, Seldom, Sometimes, Often, Always
Screen Results EVER IPV PREVALENCE By Screen Type * All non-significant *
Screen Results Current IPV PREVALENCE By Screen Type **p <0.04
We asked the women: How comfortable were you answering the questions? Did you answer questions honestly? Were you worried about computer confidentiality? How comfortable were you discussing violence with your provider? * All non-significant
We asked the providers: Did the screen enable you to do a better job as a clinician? How helpful was screen in identifying IPV? Did the screen make the visit more efficient? How comfortable were you talking about violence? * All non-significant
CONCLUSIONS • No screening approach performed better than the others • Given a higher baseline prevalence found previously in the same population, more work is needed to increase disclosure rates • Intriguing finding that mutual screen elicited a higher prevalence of current physical violence - better understanding of participation in violence required before further trials

Comfort and Honesty (mean scores) More favorable Less favorable
Confidentiality(mean scores) More favorable Less favorable
Prevalence of violence • Anonymous computer survey CADRI: 43% • Confidential computer screening: 30% • Provider assessed: 23%
Our Prior Research Anonymous A-CASI survey of 645 ethnically diverse women (15-23yr) found: • 46% of young women reported physical or sexual violence in current relationship • 84% did not mind being asked • 78% considered health provider the best person to ask them about violence • Most thought universal screening should occur in a healthcare setting

POWER • Sample size calculated based on an estimated current IPV prevalence of ~ 45%, and an expected risk difference of ~14% • Our study found a screening prevalence of current IPV = ~ 12%, and ~ 5% difference between Basic and Mutual • Therefore, we would have needed 460 women in each arm to achieve 80% Power
