A conditional probability approach to risk assessment for child sexual offenders with different classes of victim

Specific scales were developed for discriminating child sexual offenders with different classes of victim. The project demonstrates a method of individualising scores on actuarial risk assessment measured in a way that makes them more meaningful for those involved in decision-making about individual child sexual offenders. At present, the only quantifiable approach to specific decision-making relies on a general prediction of future behaviour, based on group data. The Bayesian approach is one method that can be used to assist decision-makers to use this information in ways that lead to the more appropriate management of risk. Ultimately, the better management of known child sexual offenders will lead to fewer offences and a reduction in the number of children who lives are profoundly affected by sexual victimisation.

Sentencing of male and female child sex offenders : Australian study

Research suggests that, in line with the chivalry hypothesis of female offending, a range of mitigatory factors such as mental health problems, substance abuse, and personal experiences of abuse are brought into play when women who offend against children are brought to trial. This is reflected in sentencing comments made by judges and in the sanctions imposed on the offenders, and as a result female offenders are treated differently to male offenders. The current study investigated this in an Australian context. Seven cases of female-perpetrated child sexual abuse were identified over a 6-year period through the Austlii database. Seven cases of male-perpetrated child sex abuse matched as far as possible to these were identified. Court transcripts were then located, and sentencing comments and sanctions imposed were analysed. All offenders were sentenced to imprisonment, but in general the women were more likely than the men to receive less jail time and lower non-parole periods because their personal backgrounds or situation at the time of the offending (i.e., difficulties with intimate relationship, male dependence issues, depression, loneliness and anger) were perceived as worthy of sympathy, and they were considered as likely to be rehabilitated. Further investigations are needed to support these findings.

Factors influencing the relationship between sexual abuse and academic achievement

This study examined factors expected to influence the relationship between sexual abuse and academic achievement in an adolescent inpatient psychiatric population. It was found that sexual abuse combined with either low intelligence, substance abuse, internalising behaviour problems or externalising behaviour problems predicted poor academic achievement. The supporting portfolio aims to discuss the proposed relationship between attachment and adolescent depression, highlighting the clinical relevance of this body of research with four cases of adolescent depression.

Relationship between childhood abuse and psychosexual adjustment in adult women

Study 1 found that poor attachment relationships, dysfunctional family environments, re-victimisation experiences and poor coping skills contibute towards mental health problems as well as the child abuse experiences. Study 2 implemented a therapy program that demonstrated an improvement in the sexual response of women who experienced childhood sexual assault.

Silence and silenced : implications for the spirituality of survivors of sexual abuse

Survivors of sexual abuse are frequently met with cultures of silence which make it difficult for their experiences to be acknowledged. Furthermore, many have been subjected to threats and intimidation in efforts to ensure that they remain silent about what has happened to them. One response to such experiences is to keep oneself busy and avoid ever being quiet enough to experience a sense of silence within. However, many spiritual traditions promote the embracing of silence as essential for those seeking spiritual development. This paper explores these diverse experiences of silence for survivors of sexual abuse and considers why spiritualities which promote silence can be problematic.

What were they thinking? An exploration of child sexual offenders' beliefs using a lexical decision task

Cognitive distortions have been afforded a key role in the offending behaviour of child sexual offenders. While the mechanisms underlying cognitive distortions are not fully understood, they are generally thought to reflect entrenched beliefs that distinguish child sexual offenders from other individuals. We investigated this hypothesis using a robust experimental technique called the lexical decision task. Child sexual offenders, offender controls, and non-offender controls completed a lexical decision task in which they responded to words that completed sentences in either an offence-supportive or nonoffence-supportive manner. Contrary to predictions, child sexual offenders did not respond faster to words that were consistent with offence-supportive beliefs, relative to controls. However, they did show accelerated recognition for word stems supporting external locus of control beliefs. These results highlight the need to use cognitive experimental methods to study child sexual offenders' beliefs, and the importance of investigating potential alternative drivers of cognitive distortions.

The effects of visual priming on information processing in child sexual offenders

Child sexual offenders are hypothesized to hold offence-supportive beliefs that set them apart from others. The current study seeks support for this view via a cognitive-experimental approach. Child sexual offenders and offender controls were exposed to pictures of semi-clothed children (priming condition) or clothed, mature adults (control condition). Participants then read ambiguous sentences describing children's actions that could be interpreted in a sexualized manner. Next, participants completed a surprise recognition test in which half the sentences were re-presented in an unambiguously sexual form, and half in an unambiguously non-sexual form. Contrary to hypotheses, primed and/or control child sexual offenders did not show a memory bias for sexualized sentences, suggesting that they did not interpret the original sentences in line with offence-supportive beliefs. Results raise questions about whether child sexual offenders universally hold abnormal beliefs that facilitate their offending. Results also highlight the need for further experimental research within this field.

What's in a measure? A multi-method study of child sexual offenders' beliefs

The hypothesis that child sexual offenders (CSOs) hold distorted, offence-supportive beliefs is usually investigated using interview and questionnaire techniques. However, in light of various problems associated with the use of these techniques, researchers are increasingly turning to cognitive-experimental approaches. To date, no study has examined potential differences in the nature of the beliefs that are revealed using interview, questionnaire, and experimental methods. In this study, data is gathered using these three methods and the results triangulated. CSOs are interviewed and the content categorised into five belief types. CSOs and offender controls then complete a questionnaire measure of offence-supportive beliefs and an experimental task (Rapid Serial Visual Presentation-Modified, or RSVP-M), which uses sentence reading times to explore content held in cognitive structures. As hypothesised, CSOs showed evidence of holding distorted beliefs according to the interview and questionnaire measures. Against predictions, however, CSOs did not show evidence of holding distorted belief structures on the RSVP-M task. In fact, the three methods showed no agreement regarding the belief types each CSO was deemed to hold. These results raise important questions about the phenomena and potential artefacts measured by each method.

Identification of five fundamental implicit theories underlying cognitive distortions in child abusers : a preliminary study

Qualitative analysis of interviews with 22 child abusers found strong evidence for Ward and Keenan's (1999) proposal that there are five implicit theories in child abusers that account for the majority of their cognitive distortions/thinking errors. These implicit theories are: Child as a sexual being where children are perceived as being able to and wanting to engage in sexual activity with adults and also are not be harmed by such sexual contact; Nature of harm where the offender perceives that sexual activity does not cause harm (and may in fact be beneficial) to the child; Entitlement where the child abuser perceives that he is superior and more important than others: and hence is able to have sex with whoever, and whenever, he wants; Dangerous world where the offender perceives that that others are abusive and rejecting and he must fight to regain control; and Uncontrollable where the offender perceives the world as uncontrollable and hence he believes that circumstances are outside of his control. There was no evidence for any other type of implicit theory. Results of the study also indicated that there was a significant difference in terms of the endorsement of the Dangerous world implicit theory between participants reporting a history of child sexual abuse and those who did not. Offenders against male victims were significantly more likely to endorse the Child as a sexual being and Dangerous world implicit theories compared to men who had offended against female children.

Delayed allegations of sexual abuse, complainant credibility and juror verdict

This study investigated laypersons' perceptions of memory evidence in a mock childhood sexual abuse trial. Results indicated that delay, memory type (continuous vs. recovered) and the nature of the alleged sexual assault (penetrative vs. fondling) influenced both how witnesses were perceived and the outcome of the trial.

Assessment of first sexual intercourse in young women with a history of childhood sexual abuse

Women reporting childhood sexual abuse (CSA) that involved actual or attempted penetration may not identify this as their first sexual intercourse. Data were drawn from a population-based, prospective cohort study spanning adolescence to adulthood. CSA prior to age 16 and age of first sexual intercourse with a male were assessed retrospectively. More than half of women reporting CSA in the form of actual or penetrative abuse reported an age of first sexual intercourse at or beyond 16 years. Direct questioning about CSA is needed to accurately ascertain sexual history.

Childhood sexual abuse and adolescent eating disorder : findings from the Victorian Adolescent Health Cohort study

Objective: To examine the relationship between childhood sexual abuse (CSA) before the age of 16 years and later onset of bulimia and anorexia nervosa symptoms in females.

Design: A longitudinal cohort study of adolescents observed from August 1992 to March 2003. The cohort was defined in a 2-stage cluster sample using 44 Australian schools in Victoria.

Setting: Population based.

Participants: A total of 1936 persons participated at least once and survived to the age of 24 years, including 999 females. The mean (SD) age of females at the start of follow- up was 14.91 (0.39) years; and at completion, 24.03 (0.55) years.

Main Exposure: Self-reported CSA before the age of 16 years was ascertained retrospectively at the age of 24 years.

Outcome Measures: Incident Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition)–defined partial syndromes of anorexia and bulimia nervosa were identified between waves 4 (mean age, 16.3 years) and 6 (mean age, 17.4 years) using the Branched Eating Disorder Test.

Results: The incidence of bulimic syndrome during adolescence was 2.5 (95% confidence interval, 0.80-8.0) times higher among those who reported 1 episode of CSA and 4.9 (95% confidence interval, 1.9-12.7) times higher among those who reported 2 or more episodes of CSA, compared with females reporting no episodes, adjusted for age and background factors. The association persisted after adjusting for possible confounders or mediators measured 6 months earlier, including psychiatric morbidity and dieting behavior. There was little evidence of an association between CSA and partial syndromes of incident anorexia nervosa.

Conclusion: Childhood sexual abuse seems to be a risk factor for the development of bulimic syndromes, not necessarily mediated by psychiatric morbidity or severe dieting.
