Possession of Child Pornography and Likelihood of Contact Offenses

Does Treatment Volunteerism Effect Recidivism?

October 2, 2013
Grady, Edwards, Pettus-Davis, and Abramson (2012) found that sex offenders who volunteerd for participation in sex offender treatment did not demonstrate any difference in recidivism rates when compared to sex offenders who did not volunteer to participate in treatment. Meaning, an offender's proclaimed wish to particiapte in treatment does not translate into a reduction in rates of recidivism.

Gender Differences in Prosecutin Acceptance of Child Sexual Abuse Cases

Edelson (2012) found that cases involving male victims were significantly less likely to be accepted for prosecution than cases involving female victims.
 
Only two variables were discovered to account for this difference. The first variable was the relationship of the child to the perpetrator. Females were more likely than males to be abused by biological fathers, and males were more likely to be abused my mother's ...

Reliability of Sex Offender Risk Assessment Tools

January 10, 2013
Risk assessment measures are important tools used in the evaluation of sexually violent predators (SVP's). Although they are only one source of data used to inform expert opinions that are offered in SVP committment proceedings (as well as other legal arenas), they are instruments used when the stakes are high and need to be as reliable and valid as possible. Miller, Kimonis, Otto, Kline, and Asserman (2012) examined ...

Risk Assessment of DD/MR Adult Male Sex Offenders

STATIC-99 more overestimate risk
RRASOR may be more accurate tool for DD/MR sex offenders

PAI Antisocial Features scale as proxy for psychopathy

October 31, 2011
More recently, research has been conducted regarding the validity of using the PAI as a measure of psychopathy (Douglas et al., 2007).  As stated above, using the PCL-R is the current standard in the field. However, due to the limitations of the instrument, there is an increased emphasis on using the PAI in place of the PCL-R (Douglas et al., 2007).
Salekin et al. (1997) observed scores on the PCL-R, PAI -ANT scale, ...

PAI & Female Sex Offenders

October 28, 2011
Presently, only one published study exists examining the PAI results of female sex offenders. Turner et al. (2008) researched the characteristics of 90 female sex offenders regarding offense and personality traits. Based on these author’s results, they found three distinct personality-based subtypes of female sex offenders by self-report PAI scores. The first subtype had subclinical psychopathology levels but had ...

PAI & Sex Offenders

October 23, 2011
Psychopathology and maladaptive personality functioning play a significant role in sexual offending (Laulik, Allam, & Sheridan, 2007). Edens et al. (2001) stressed that personality disorders are relevant in forensic and correctional settings because of the inclusion of personality disorder diagnoses into various legal statutes and case law, specifically noting the Civil Commitment of Sexually Violent Predators Act, ...

Psychopathy & Sex Offenders

October 21, 2011
Similar to female offenders and psychopathy, research on psychopathy and sex offenders is limited. In addition, the usefulness of the PCL-R and its derivatives is debatable (Hare, 2004). Hare reported that psychopathy is more strongly associated with general and violent offending than with sexual offending. This may be a result of child molesters not being psychopaths, rather, generalized offenders who happen to also ...

Psychopathy & Female Offenders

October 17, 2011
There is a paucity of research on the validity of using the PCL-R or its derivatives with female offenders (Salekin, Rogers, & Sewell, 1997). These authors elaborated that pronounced gender differences for psychopathy and APD have been observed, despite the limited research. Some of the gender differences include later onset of psychopathy and APD for females than males; females exhibit less overt aggression than ...

Limitations of the PCL-R

October 12, 2011
Although there is an abundance of research suggesting that the PCL-R is the “gold standard”, it has some limitations. First, the PCL-R is highly labor intensive to administer and score. Requirements for accurate scoring include a trained examiner, a semi-structured clinical interview, and extensive review of all available institutional file data. This often results in a trained mental health professional ...

Psychopathy & Sexual Recidivism

October 9, 2011
Some researchers have found significant relationships between psychopathy and sexual recidivism (Hanson & Harris, 2000; Hemphill, Hare, & Wong, 1998; Hildebrand, de Ruiter, & de Vogel, 2004; Salekin et al., 1996) whereas other researchers have found competing results (Barbaree, Seto, Langton, & Peacock, 2001; Olver & Wong, 2006). Barbaree et al. (2001) found that the PCL-R predicted general and serious ...

Psychopathy & Recidivism

October 6, 2011
More recent debate and research has focused on the use of specific assessments of offender personality traits believed to correlate with offender recidivism, in particular the PCL-R and its derivatives. Salekin, Rogers, and Sewell (1996) reviewed 18 studies, yielding 29 effect sizes, that investigated the relationship between the PCL/ PCL-R and violent and nonviolent recidivism. These authors divided the studies into ...

The principle objective of police interviewing is to gather relevant information about the suspected or reported crime. There are two types of interview techniques: the Reid technique, primarily used in the United States; and the PEACE model, primarily used in the United Kingdom. Researchers have expressed concerns regarding the Reid technique due to its guilt-presumptive and confrontational aspects, and thus, recommend ...
