As mobile devices become increasingly versatile and integrated into the daily lives of youth, their use for sexual purposes has also risen. One such example is sexting, which enables adolescents to engage in digital sexual communication and expression via nude and semi-nude imagery. This chapter presents an overview of sexting research among adoles...

Sending unsolicited sexts is increasingly recognised as harmful and, in some countries, constitutes a criminal offence. Recipients of unwanted/unexpected sexts often report compromised mental health, yet it is currently unknown how people deal with these sexting experiences. Using a mixed-methods approach, this study explored help-seeking behaviour...

Although consensual sending of sexts between adolescents is considered developmentally appropriate, it may also entail a range of negative consequences. Current sexting research lacks a comprehensive theoretical framework identifying a range of risk and protective factors underpinning adolescent consensual sending of sexts across individual, interp...

The exchange of intimate messages, images, and videos via digital means, also referred to as sexting, has drawn considerable academic attention in recent years. Specifically, cross-sectional research has indicated that sexting can be associated with harmful outcomes such as depression, anxiety, and cyberbullying. However, there is currently limited...

While pornography provides opportunities for sexual exploration for young people, early and easy access also has possible negative implications for young people’s behavioural and sexual development. Parental responsibilities concerning their children’s consumption of pornography are largely misunderstood. This study explored parental experiences an...

Sext dissemination (i.e., the online sharing of sexually explicit images) has the potential to result in legal, social, and psychological harms. Recent research has shown that this behavior can be consensual or non-consensual in nature; yet little is known about how motivations or attitudes may differ between these forms, or with gender. This study...

With the increased ubiquity of digital technology, sexting behaviours, defined as the online sending, receiving, or disseminating of sexually explicit messages, images, or videos, have become increasingly frequent, particularly among young adults. While prior research found sexting behaviours to be associated with cyberbullying behaviours, the role...

Sexting is a common form of sexual communication that is often considered normative and beneficial despite some research highlighting its negative social, psychological, and legal repercussions. Using protection motivation theory (PMT), this study examines how young adults weigh the pros and cons of sending consensual sexts, sexting under pressure,...

Cyberbullying behaviours can result in serious adverse mental health outcomes. We report evaluation findings from the Geelong Cyber Cats, a one-day community-based cyberbullying prevention intervention targeting Year 7 adolescents. The longitudinal, mixed-methods evaluation involved students completing surveys at baseline (N = 309), intervention co...

Cyberbullying and non-consensual sexting are prevalent and potentially harmful online behaviours. However, little is known about the attitudes and beliefs that underpin these behaviours in ciswomen and cismen and the extent to which they explain the online experiences of trans and gender diverse (TGD) people. A sample of 638 ciswomen, 722 cismen, a...

Child sexual exploitation (CSE) is a significant global problem. Interventions implemented with youth affected by CSE frequently target singular adjacent issues (e.g., substance misuse or running away); however, research indicates these interventions are most efficacious when they simultaneously treat CSE sequelae (e.g., emotion dysregulation) pair...

Cyberbullying can present a serious risk for adolescents and young adults, with severe effects on victims including adverse mental health outcomes and increased risk of suicide. Transgender and gender diverse (TGD) individuals are significantly more likely to experience cyberbullying. However, little is presently known about the lived cyberbullying...

Child sexual exploitation (CSE) is a serious and persistent global issue affecting up to 5% of the child and youth population worldwide; yet there is no universally accepted definition. To develop a theoretically robust definition of CSE, this review systematically synthesized literature examining CSE definitions aiming to develop a conceptual mode...

Pressure to send sexually explicit messages, or ‘sexting coercion’ is associated with adverse mental health outcomes and sexual risk behaviors. This study explores Differentiation of Self (DoS) as a potential protective factor to reduce susceptibility to sexting coercion. A convenience sample of 399 Australian participants, aged 18 to 21 years (Mag...

While sexting behaviours have attracted increasing research focus over the last decade as both normative and deviant forms of sexual activity, little attention has been paid to their potential associations with sexual preoccupation and heightened interest in sex. The current study sought to identify whether sexual preoccupation significantly predic...

The phenomenon of “slutpages,” tied to high schools, fraternities, and the military, used to post, share, and comment on nude and semi-nude images of women, has emerged in mass media. To our knowledge, this is the first study to empirically investigate slutpage use behaviors including: visiting slutpages, posting nude images/videos online without c...

There is a growing research interest in cyber dating abuse (CDA). CDA includes abusive online behavior toward a current or former intimate partner, such as aggression, control, harassment, and humiliation. Despite the potential overlap and reciprocal relationship of CDA and intimate partner violence, there remains considerable paucity in research e...

“Slutpages” are a pernicious form of online image-based evaluative voyeurism (OIBEV), whereby (sexualized) images of women are posted on webpages for (predominantly) male groups to rate and comment. Despite media and public concern, OIBEV sites have garnered limited empirical study. This paper presents the first analysis of OIBEV site visitation mo...

Image-based sexting constitutes a visual form of sexual communication. Yet, the degree to which satisfaction with one's physical appearance emboldens or inhibits young adults from engaging in sexting behaviors is poorly understood. This study investigated whether body esteem related to specific body parts and functions can uniquely predict sending...

Adults’ assessments of the credibility of children’s reports are affected by factors including the frequency of abuse, reporting delays and the child’s age. The present study examined whether similar factors affect the perceived credibility of children reporting physical abuse, which is more common than sexual abuse. Two hundred and eight mock juro...

Instruments designed to appraise the risk of young people acting violently are sometimes used to measure changes in risk over the course of treatment. This study examined measurement error, reliable change and the relationship between change and recidivism of three youth violence assessment instruments, the SAVRY, VRS-YV and SAPROF-YV. Each instrum...

Despite suggestions that sexting could be used to enhance relationship satisfaction, there is limited research exploring the impact of sexting on improving relationship satisfaction among emerging adults. This study included 348 Australian adults aged 18 to 25 years (M = 19.84, SD = 1.45, 14.1% men, 85.9% women), who reported being in a relationshi...

Sext dissemination presents policy and legislative challenges given its potential psychological, social, and legal harms. We report on a cross-national comparison of sext-image dissemination in a large sample of 1148 young adults aged 18–29 years (M = 22.54, SD = 2.50, 53.0% women, 47.0% men), either U.S. (53.8%) or Australian (46.2%) residents. Th...

The risk and protective factors in a sample of 224 Singaporean youths who have engaged in violence are investigated using the SAVRY the VRS-YV, and the SAPROF-YV. Youths in the early and middle stages of adolescence exhibited more risk factors and fewer protective factors than late stage adolescents. This may be due to cultural and societal influen...

Jurors sometimes consider inadmissible evidence in their verdicts, despite judicial instructions to disregard that evidence. Procedural justice research suggests this is because jurors are motivated to prioritise just outcomes over due process; thus, jurors’ non-compliance towards judicial instructions to disregard inadmissible evidence may be the...

This study examined the predictive validity of three assessment instruments for violent youth, the SAVRY, the VRS-YV, and the SAPROF-YV. Files relating to a sample of 233 young male offenders aged between 12 and 18 years were retrospectively reviewed to score each instrument, with reoffending data extracted from prison, community and juvenile justi...

Importance: Although research has examined factors associated with child sexual exploitation (CSE), consensus is lacking in regard to which factors should be prioritized, thereby hindering policy reform, prevention efforts, and development of early detection and intervention. Objective: To provide a meta-analytic synthesis of studies examining f...

This study investigated sext dissemination in a large convenience sample of young adults (N = 691, M age = 22.4, SD = 3.2, 53% female). Participants who disseminated sexts (17.4%) were more likely sexually active, and from a younger age, had requested sexts, received disseminated sexts, and reported higher dark triad trait levels. Images were usual...

The present study examined the role of political orientation and task engagement in juror decision-making. The study was conducted as a 2 (mode: laboratory versus online) × 2 (role: juror, observer) × 3 (evidence: admissible, inadmissible, control) between-subjects experiment, with participants (N = 157) recruited from a mid-sized Australian univer...

The study examined the impact of victim age, victim gender, and perpetrator gender, across five domains of witness credibility: accuracy, believability, competency, reliability and truthfulness. The study also investigated which of these sub-constructs is the best predictor of guilt. 231 adult lay-people completed a survey measuring perceived credi...

This study sought to explore whether body image self-consciousness during sexual relations predicts whether and for what reasons individuals send sexts. A series of ordinal and binary logistic regression analyses revealed that increased body image self-consciousness during sexual relations predicted consensual but unwanted instances of sexting for...

This paper reports the findings of a systematic search of published literature which reports the predictive validity of violence risk assessment tools specifically designed for use with youth. A total of 38 studies, involving 9,307 participants, reported data for six different tools; the most common of which were the SAVRY and the YLS/CMI. Each of...

The present study evaluated whether individuals with varying levels of trait body image flexibility differ in the severity, variability, and correlates of state body dissatisfaction experienced in their daily lives. One hundred and forty-seven women completed a baseline measure of trait body image flexibility, followed by a 7-day ecological momenta...

The practice of creating and sharing sexual images via technological devices, known as sexting, has received crescent attention in the past years, especially due to the increase of adolescent engagement in this behavior. Although consensual sexting is not prima facie a crime, as some research has shown, it has the potential to be a risky behavior,...

The current study explores the effect of body dissatisfaction (both stable, trait-level and specific, state-based instances in daily life) on sexting behaviors, and the impact of sending and receiving sexts on body dissatisfaction levels in daily life. One hundred and forty-seven women aged 18 to 42 years completed baseline measures of body dissati...

Sexting (e.g., conveying nude electronic images) is now common among young adults. Despite leading to negative consequences for some (e.g., harassment and unwanted dissemination), findings regarding sexting behaviors and mental health variables have been mixed. We recruited a convenience sample of young adults (N = 444, M age = 20, SD = 1) to test...

The objective of this study was to examine engagement in sexting by young adults in India and Australia, and depression, anxiety and stress as risk factors for sending sexts. A total of 298 young Australian adults (Mage = 19.98 years, 75.50% female) and 300 young Indian adults (Mage = 18.08 years, 56.33% female) completed a survey (online and hardc...

Sexting (i.e. the sending and receiving of sexually explicit images via apps or phones) is increasingly common among young adults. However, specific concerns relate to the potential social and legal implications of non-consensual sext dissemination. Whilst previous research has investigated the prevalence of non-consensual dissemination, motivation...

Child sexual assault is a global health issue, with extensive implications for legal, social, clinical, and health psychology. The perceived credibility of child victims is of considerable importance in terms of the successful prosecution of such cases. However, there has been considerable inconsistency within past research regarding how best to me...

This study investigated perceptions of victim culpability in sexual assaults against girls and women according to victim age, perceiver gender, and perceiver parental status. Overall, 420 jury-eligible participants completed an online survey recording their attributions of guilt, responsibility, and blame toward 10-, 15-, and 20-year-old girls and...

Perceived victim credibility is a crucial factor in jury decision-making, especially in the context of child sexual assault cases where there are often no corroborating witnesses. Yet despite the importance of credibility and the expanding research in this area, there remains no unified understanding of what credibility is, what domains it encompas...

Child sexual assault cases have one of the highest attrition rates throughout the justice system, with jurors’ perceptions of the credibility of the child playing a critical role in the judicial process and resulting outcomes. One of the most prominent influences on credibility is gender, specifically victim and perceiver gender. This article repor...

While the concept of credibility seems like an intuitive one, research has indicated that there is no consistent definition of this construct and that credibility may, in fact, be multidimensional. This article is the first to review how the measurement of credibility in child sexual assault cases has been conducted, with the view to improve how cr...

To date, there has been limited examination of variables that influence sentencing in child sexual abuse cases. This study examines the extent to which offence characteristics (such as the number of offences, number and age of victims), the behaviour and perceived credibility of the victim impact upon both sentence length and the setting of earlies...

Abstract Child sexual abuse (CSA) cases have one of the lowest conviction rates across all charges. While research has investigated the impact of attitudes and beliefs in judicial decision makers, little is known about the influence of medical evidence. The aim of this study was to examine how the presence or absence of evidence impacts on convicti...

Low conviction rates of child sexual assault (CSA) remain a persistent social problem in Australia. One reason for this may be the impact of attitudes regarding the victims when the evidence is weak. This article examines the effects of victim age on perceptions of credibility and verdict in a CSA case. Eleven electronic focus groups deliberated a...

Purpose – A significant issue in jury research has been the use of individual jurors to analyse jury decision-making. This paper aimed to examine the applicability of computer-mediated communication to a mock jury deliberation study. Design/methodology/approach – Groups of three to five Australian residents anonymously attended a secure chat room...

i> Purpose – Previous studies suggest that the presence of medical evidence is rare in child sexual assault (CSA) cases, and if present at all, such evidence is unlikely to identify a specific assailant. This study aims to examine the role medical evidence plays in criminal cases of CSA. Specifically, the prevalence of medical evidence in CSA cases...

One suggested reason for the low conviction rates of alleged child sexual abuse offenders relates to the attitudes and beliefs the public hold about such victims; sexual interactions starting at an earlier age; and because the oversexualisation of children and teenagers portrayed in the media may have affected perceptions as to when females are capab...

Abstract Purpose – Previous studies suggest that the presence of medical evidence is rare in child sexual assault (CSA) cases, and if present at all, such evidence is unlikely to identify a specific assailant. This study aims to examine the role medical evidence plays in criminal cases of CSA. Specifically, the prevalence of medical evidence in CSA...

Expert testimony is being used increasingly in child sexual assault cases. This study extended a prior study that examined factors related to expert testimony (evidence strength, coherence and credentials of the expert) on ratings of guilt and overall verdict. Specifically, we replicated our prior study but with two modifications: we used community...

People have strong expectations about the kinds of entities that can serve as causers. These expectations are a matter of psychology and philosophy but also, perhaps, a matter of linguistics. For example, in English, both the sentences: "The boy broke the window" (1a) and "The knife cut the bread" (1b) are acceptable descriptions of causal events,...

In metaphysics there exist long-standing, unresolved problems regarding causation. Indeed, rationalist and empiricist philosophers remain engaged in an intricate debate concerning the ontology of causal relations. We review rationalist and empiricist approaches to the problem of causality and formulate transpersonally orientated criticisms of each....

Psychological experts have been used increasingly to testify in child sexual abuse cases, yet little research has investigated what specific factors make experts effective. This study examined the potential effects that credentials, evidence strength and coherence may have on juror decision making. Sixty-four mock jurors read cases of child sexual...

We investigated college students’ perceptions of a diverse sample of animated conversational agents. We also examined the pedagogical efficacy of those agents. We found that people perceive differences among the agents on several dimensions, such as likeability, and that the agents differ in pedagogical efficacy. However, none of the characteristic...

This research identifies how English and German speakers differ in the range of situations they describe as causal and how these difference may influence causal reasoning. In Experiments 1 and 2, English and German speakers described 3D animations of complex events using CAUSE verbs (cause, get) and ENABLE verbs (let, enable). As predicted, English...
