Sexting prevalence and correlates: a systematic literature review.

Despite considerable controversy and speculation regarding sexting behaviour and its associated risks, to date there has been no integration and analysis of empirical literature on this topic. To collect and synthesise findings of the prevalence of sexting, its correlates, and the context in which it occurs, a systematic search of databases was conducted. Thirty-one studies, reporting on sexting prevalence and a diverse range of related variables, met inclusion criteria. The estimated mean prevalence weighted by sample size was calculated, with trends indicating sexting is more prevalent amongst adults than adolescents, older age is predictive of sexting for adolescents but not adults, and more individuals report receiving sexts than sending them. The correlates of sexting behaviour were grouped in terms of demographic variables, sexual and sexual risk behaviours, attitudes towards sexting, perceived outcomes of sexting, motivations for sexting, mental health and well-being variables, and attachment dimensions. Findings are discussed in terms of the trends indicated by the data, which provided substantiation that sexting behaviour is associated with numerous behavioural, psychological, and social factors. Limitations of the current research literature and future directions are also presented.

The influence of medical and behavioral evidence on conviction rates in cases of child sexual abuse

Child sexual abuse 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 conviction. A sample of 113 child sexual abuse cases from Australia were coded for the types of evidence that were presented as well as other relevant descriptive data. The most significant predictor of verdict was the behavior of the child rather than the presence of medical evidence. This finding suggests that greater attention might be given to the collection and reporting of this evidence in future trials.

The effects of evidence, coherence and credentials on jury decision-making in child sexual abuse trials

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 samples as opposed to university students, and participants made their decisions in groups of 12 (as in the case of juries where one decision represents the overall group) rather than having participants decide and submit their verdicts and guilt ratings individually. Consistent with the prior (less ecologically valid) study, credentials of the expert had negligible impact. Evidence that was high in strength elicited a relatively high guilt rating even when the testimony was low in coherence. Further, it appears that when participants deliberate in a group (as in the case of juries) they are more conservative in their judgements (i.e., they are less likely to give a guilty verdict) compared to individual jurors who make their decisions alone. These findings suggest that caution must be exercised when drawing conclusions about the generalisability of prior research findings where participants did not engage in group deliberation.

Sentencing in child sexual assault cases: factors influencing judicial decision-making

Abstract 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 earliest parole dates. Analyses conducted using data from 66 adjudicated cases of child sexual assault from the County Court of Victoria, Australia revealed that longer sentences were handed down to offenders who had perpetrated multiple offences, or who had committed offences against younger children. Lower levels of victim credibility were associated with shorter sentences and earlier parole dates for offenders, which were also associated with the presence of more harmful behavioural indicators of abuse. The findings are discussed regarding the importance of presenting evidence about the behaviour of victims following sexual abuse in criminal trials.

The Effect of Gender on Perceptions of Credibility in Child Sexual Assault Cases: A Systematic Review

ABSTRACT 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 reports the findings of a systematic search of the literature exploring the impact of these factors on perceptions of victim credibility. Results suggest that overall females tend to rate victim credibility higher than do males; however, this gender effect is minimized when the alleged perpetrator is not the biological parent of the victim. There is little support for a victim gender effect, such that potential jurors’ ratings of victim credibility does not appear to be influenced by the gender of the victim. The review highlights the lack of consistent and comprehensive measurement of credibility. Legal implications are discussed.

Simulated jury decision making in online focus groups

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 and participated in a semi‐structured discussion about a simulated child sexual assault scenario. Deliberation transcripts were analysed thematically using NVivo. A hermeneutic framework was used to analyse the deliberation transcripts.Findings – Five interrelated themes were revealed, each reflecting the tools online juries used to communicate, create meaning, and arrive at a verdict. Electronic jury deliberation promoted an understanding of how people make sense of child sexual assault cases in Australia today.Originality/value – This study advanced the understanding of online decision making in a child sexual assault scenario. It demonstrated that knowledge of ...

The development of a conceptual model of perceived victim credibility in child sexual assault cases

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 encompasses and how it can be comprehensively measured. This article proposes a conceptual model of perceived victim credibility encompassing the five domains of accuracy, believability, competency, reliability and truthfulness. These domains are defined, distinguishing between the various sub-constructs based on the items they encompass. This model provides a theoretical framework for the development of an instrument to measure perceived victim credibility in future research studies. This is valuable for both researchers and professionals working in the area of child sexual assault in terms of understanding the construct of credibility and unifying the approach to measuring and comparing attitudes.

The Effects of Victim Age, Perceiver Gender, and Parental Status on Perceptions of Victim Culpability When Girls or Women Are Sexually Abused:

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 women in relation to sexual assault. Attributions of culpability were affected by whether the victim physically or verbally resisted the abuse, wore sexually revealing clothes, or was described as having acted promiscuously. Fifteen-year-old victims were perceived as more culpable for the abuse than 10-year-old victims. Implications of these findings are discussed.

The Development and Validation of the Child Sexual Assault Victim Credibility Scale: An Instrument to Measure Laypersons’ Perceptions of Victim Credibility

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 measure credibility, and to date, there exists no broadly accepted scale for the measurement of lay perceptions of credibility of child victims. The current study evaluates a proposed Child Sexual Assault Victim Credibility Scale (CSAVCS) and includes the results of both a pilot and scale validation study. A two-phase approach for instrument development was adopted. Thirty-six participants from the general community were involved in the pilot study (Phase I), comprising six males and 30 females. A further 210 participants (61 males and 149 females) were included in the scale validation sample (Phase II). Participants read a transcript of a child disclosing sexual abuse and rated their perceptions of the child’s accuracy, believability, competency, reliability, and truthfulness. The scale’s reliability and internal validity were successfully tested and modified in Phase I and subsequently validated and confirmed in Phase II. There was strong evidence of internal consistency, reliability, and content validity. Following model respecification, the final 23-item model was confirmed. The evaluation of the CSAVCS was a crucial first step and will be useful for future research exploring perceived credibility. Using a validated and reliable scale may serve to improve the consistency of measurement of credibility and to facilitate comparisons among studies.

Measurement of victim credibility in child sexual assault cases: a systematic review

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 credibility is psychometrically measured. Our findings indicate that the majority of experiments have been conducted in the United States (67%), have been based primarily on undergraduate students as participants (67%), and primarily investigated cases involving a male defendant and female victim (69%). Ultimately, among experiments investigating victim credibility, approximately 60% of all measures were based on a single item and 53% used materials not based on the testimony of the child. Moreover, credibility has been measured using a great variety of constructs such as believability, honesty, truthfulness, suggestibility, accuracy, and reliability. A more nuanced and consistent definition of credibility will be needed to facilitate meaningful applications of the research literature.
