A 32-nation study of violence against dating partners by university partners found that about a third had been violent, and most incidents of partner violence involve violence by both the man and woman, according to Murray Straus, founder and co-director of the Family Research Laboratory at the University of New Hampshire. The second largest category was couples where the female partner was the only one to carry about physical attacks, not the male partner.
32カ国のカップルを調査。3分の1が暴力沙汰を経験したそうだけど、女性が手を出し、男は耐える構図がけっこう多い。ただ、男女に体格差があると、女が手を出しても冗談にしか見えず、男が手を出すと脅しになる。
