WEDNESDAY, Feb. 10, 2016 (HealthDay News) -- Lesbian, gay, bisexual and transgender (LGBT) teens who experience severe harassment can suffer from serious mental health problems, a new study suggests.
"With bullying, I think people often assume 'That's just kids teasing kids,' and that's not true," said study author Brian Mustanski, director of Northwestern University's Institute for Sexual and Gender Minority Health and Wellbeing in Chicago.
"If these incidents, which might include physical and sexual assaults, weren't happening in schools, people would be calling the police," he said in a university news release.
"You can't equate someone giving you a dirty look with someone physically assaulting you. Victimizations that are more severe are going to have bigger effects. We scored them in a way that represented that, and we saw they had a profound effect on mental health rates over time," Mustanski explained.
In the study, the researchers followed almost 250 LGBT youth in Chicago for four years. During that time, nearly 85 percent of the participants had decreasing levels of harassment, about 10 percent had significant increases in harassment, and about 5 percent had consistently high levels of harassment.
Females were more likely than males to have decreasing levels of harassment during the study period, and males were more likely to be subjected to physical and verbal assaults, the researchers found.
LGBT youth at greatest risk for lasting mental health problems -- such as depression and post-traumatic stress disorder -- were those who suffered moderate harassment (such as having things thrown at them) that increased over time and those who had continuously high levels of harassment (such as physical or sexual assault) during the study.
"We were happy to see that for most kids, the levels of victimization were lower overall or decreasing over time. But we were struck by how severe it was for some of these kids who were getting highly victimized over their four years of high school," Mustanski said in the news release.
"If that's your experience for several years of high school, you can imagine how scarring that would be," he added.
The findings were published recently in the American Journal of Public Health.
