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...]

Perpetration of teen dating violence in a networked society
Korchmaros JD, Ybarra ML, Langhinrichsen-Rohling J, boyd d, Lenhart. Perpetration of teen dating violence in a networked society. Cyberpsychol Behav Soc Netw. 2013;16(8):561-567. doi: 10.1089/cyber.2012.0627 Abstract: Teen dating violence (TDV) is a serious form of youth violence that youth fairly commonly experience. Although youth extensively use computer-mediated communication (CMC), the epidemiology of CMC-based TDV is largely unknown. This study examined how perpetration of psychological TDV using CMC compares and relates to perpetration using longer-standing modes of communication (LSMC; e.g., face-to-face). Data from the national Growing up with Media study involving adolescents aged 14-19 collected from October 2010 to February 2011 and analyzed May 2012 are reported. Analyses … [Read more...]
