Sexual assault in school, mental health and suicidal behaviors in adolescent women in Canada.

Adolescent women (N = 1,025) in grades 7 through 12 in a stratified random sample of Alberta high schools completed measures of emotional problems and suicidal behavior in the past six months, and of frequency and type of sexual assault (including sexual harassment) experienced in school. It was found that 23% has experienced at least one event of assault (sexual touching, sexual threats or remarks, or an incident of indecent exposure); 4% had "often" experienced one or more of these assaults or harassments. Those experiencing a high number of sexual assaults or harassments were significantly more likely to have clinical profiles on the measures of emotional disorder; 15% of 38 women experiencing frequent, unwanted sexual touching had "often" made suicidal gestures or attempts in the previous six months, compared with 2% of 824 women with no experience of sexual assault.
