Predicting the Emergence of Sexual Violence in Adolescence.

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 regression models estimated the odds of first perpetrating each of the five types of SV within the context of other variables (e.g., rape attitudes). Average age at first perpetration was between 15 and 16 years of age, depending on SV type. Several characteristics were more commonly reported by perpetrators than non-perpetrators (e.g., alcohol use, other types of SV perpetration and victimization). After adjusting for potentially influential characteristics, prior exposure to parental spousal abuse and current exposure to violent pornography were each strongly associated with the emergence of SV perpetration-attempted rape being the exception for violent pornography. Current aggressive behavior was also significantly implicated in all types of first SV perpetration except rape. Previous victimization of sexual harassment and current victimization of psychological abuse in relationships were additionally predictive of one's first SV perpetration, albeit in various patterns. In this national longitudinal study of different types of SV perpetration among adolescent men and women, findings suggest several malleable factors that need to be targeted, especially scripts of inter-personal violence that are being modeled by abusive parents in youths' homes and also reinforced by violent pornography. The predictive value of victimization for a subsequent first SV perpetration highlights the inter-relatedness of different types of violence involvement. Universal and holistic prevention programming that targets aggressive behaviors and violent scripts in inter-personal relationships is needed well before the age of 15 years.

Project description:This research longitudinally explored adolescent pornography (porn) consumption and its association with sexual development in early and middle adolescence. A four-wave design with half-year intervals investigated pornography consumption and different (sexual) activities, such as masturbation, French kissing, petting, giving/receiving manual and oral sex, and intercourse, among 630 respondents (47.9% female, mean age 13.7 years; SD = 0.48) years at T1). A latent growth mixture analysis of pornography consumption revealed two groups with relatively low pornography (LP; 51.8% of the boys, 91.4% of the girls) versus high pornography (HP; 48.2% of the boys; 8.6% of the girls) consumption across time. At T1, HP boys on average watched pornography less than once a month, but more than once a year at T1. At T4, their average pornography use had increased to almost one to two times a week. LP boys never watched pornography at T1. At T4, their average pornography use was still less than once a year. At T1, HP girls never watched pornography, but consumption increased to almost one to three times a month at T4. Across waves of the study, LP girls (almost) never watched pornography. A discrete-time survival mixture analysis of sexual developmental patterning indicated that, compared to their LP peers, both girls and boys in the HP groups showed accelerated development of masturbation, petting, and receiving manual sex. Girls in the HP group were also more inclined to receive oral sex, whereas boys in the HP group also showed earlier and more frequent manual sex and intercourse. Thus, whereas the HP group of boys was substantially larger compared to that of girls, pornography consumption was related to accelerated development of sexual activities for both genders across early and middle adolescence. The discussion deliberates on pornography as a driving force in adolescent sexual development versus pornography as a medium of choice for sexually advanced adolescents.

Project description:ObjectivesTo establish a James Lind Alliance (JLA) Priority Setting Partnership (PSP) to identify research priorities relevant to the health and social care needs of adults with lived experience of recent and/or historical sexual violence/abuse.ParticipantsAdults (aged 18+ years) with lived experience of sexual violence/abuse (ie, 'survivors') were consulted for this PSP, alongside healthcare and social care professionals who support survivors across the public, voluntary, community, independent practice and social enterprise sectors.MethodsIn line with standard JLA PSP methodology, participants completed an initial online survey to propose research questions relevant to the health and social care needs of survivors. Research questions unanswered by current evidence were identified, and a second online survey was deployed to identify respondents' priorities from this list. Questions prioritised through the second survey were presented at a consensus meeting with key stakeholders to agree the top 10 research priorities using a modified nominal group technique approach.Results223 participants (54% survivors) provided 484 suggested questions. Seventy-five unique questions unanswered by research were identified and subsequently ranked by 343 participants (60% survivors). A consensus meeting with 31 stakeholders (42% survivors) examined the top-ranking priorities from the second survey and agreed the top 10 research priorities. These included research into forms of support and recovery outcomes valued by survivors, how to best support people of colour/black, Asian and minority ethnic and lesbian, gay, bisexual, transgender, and queer (LGBTQ+) survivors, improving access to high-quality psychological therapies, reducing public misconceptions/stigma, the impact of involvement in the criminal justice system on well-being, and how physical and mental health services can become more 'trauma informed'.ConclusionsThese research priorities identify crucial gaps in the existing evidence to better support adult survivors of sexual violence and abuse. Researchers and funders should prioritise further work in these priority areas identified by survivors and the professionals who support them.
