Perceptions of middle school youth about school bullying

Ybarra ML, Espelage DL, Valido A, Hong JS, Prescott TL. Perceptions of middle school youth about school bullying. J Adolesc. 2019 Aug;75:175-187. doi: 10.1016/j.adolescence.2018.10.008. Epub 2018 Nov 7. Abstract: Introduction: Bullying prevention remains a major focus for schools yet prevention programs have yielded limited efficacy. This suggests that efforts to make the programs more salient for youth may result in greater reductions in bullying behavior. Methods: To inform the development of a text messaging-based bullying prevention program for middle school youth, we conducted two online, asynchronous focus groups with 37 youth in grades 6-8. Youth were recruited across the United States using an online panel. Topics and questions were posted twice-daily across three days; … [Read more...]

The effect of a text messaging based HIV prevention program on sexual minority male youths: A national evaluation of information, motivation and behavioral skills in a randomized controlled trial of Guy2Guy

Ybarra ML, Liu W, Prescott TL, Phillips II G, Mustanski B. The effect of a text messaging based HIV prevention program on sexual minority male youths: A national evaluation of information, motivation and behavioral skills in a randomized controlled trial of Guy2Guy. Journ. of Adolesc. 2018. https://doi.org/10.1007/s10461-018-2118-1 Abstract: There is a paucity of literature documenting how the constructs of the Information–Motivation–Behavioral Skills (IMB) model are affected by exposure to technology-based HIV prevention programs. Guy2Guy, based on the IMB model, is the first comprehensive HIV prevention program delivered via text messaging and tested nationally among sexual minority adolescent males. Between June and November 2014, 302 14–18year old gay, bisexual, and/or queer … [Read more...]

Characteristics of bias-based harassment incidents reported by a national sample of U.S. adolescents

Jones LM, Mitchell KJ, Turner HA, Ybarra ML. Characteristics of bias-based harassment incidents reported by a national sample of U.S. adolescents. Journ of Adolesc. 2018; 65: 50-60. https://doi.org/10.1016/j.adolescence.2018.02.013 Abstract Using a national sample of youth from the U.S., this paper examines incidents of bias-based harassment by peers that include language about victims' perceived sexual orientation, race/ethnicity, religion, weight or height, or intelligence. Telephone interviews were conducted with youth who were 10–20 years old (n = 791). One in six youth (17%) reported at least one experience with bias-based harassment in the past year. Bias language was a part of over half (52%) of all harassment incidents experienced by youth. Perpetrators of bias-based harassment … [Read more...]

Predicting the emergence of sexual violence in adolescence

Ybarra ML, Thompson RE. Predicting the emergence of sexual violence in adolescence. Prev Sci.  Published online July 07, 2017. doi: 10.1007/s11121-017-0810-4. Abstract: This study aims to report the epidemiology of sexual violence (SV) perpetration for both female and male youth across a broad age spectrum. Additionally, the etiology of SV perpetration is examined by identifying prior exposures that predict a first SV perpetration. Six waves of data were collected nationally online, between 2006 and 2012, from 1586 youth between 10 and 21 years of age. Five types of SV were assessed: sexual harassment, sexual assault, coercive sex, attempted rape, and rape. To identify how prior exposures may predict the emergence of SV in adolescence, parsimonious lagged multivariable logistic … [Read more...]

Participants were cisgender males ages 14 to 18 years old who were gay, bisexual, and/or … [Read more...]
