Background. Previous studies have examined short-term effectiveness of dome
stic violence instruction. We studied the long-term effectiveness (LTE) and
long-term retention (LTR) of formal instruction about domestic violence.
Methods. A general knowledge survey on domestic violence was given before,
1 month after, and 2 years after 3 hours of instruction to medical students
. Good LTE was defined as significant improvement in responses between the
first and third surveys. Good LTR was defined as lack of a significant decr
ease in results between the second and third surveys.
Results. Two years after the instruction, 104 of 148 (70%) participated. kn
owledge of rates of domestic violence against women showed neither good LTE
nor good LTR. Responses showed good LTE and LTR concerning domestic violen
ce incidence among men, ethnic and socioeconomic groups being equally repre
sented, victims not being personally responsible for the abuse, and physici
ans nor being required to report domestic violence in the survey state. Res
ponses showed poor LTR and LTE regarding rates of domestic violence in wome
n and abused persons being unable to simply leave their situation.
Conclusions. Some improvement in domestic violence awareness was seen 2 yea
rs after instruction. However, some information was not retained. Domestic
violence instruction should be reemphasized throughout medical school.
