The Screening Scale for Pedophilic Interests (SSPI) is a structured rating scale of four child victim characteristics: number, age, gender, and relationship of victims. Sexual offenders against children who score higher on the SSPI are more likely to be identified as having pedophilic sexual arousal and are more likely to sexually reoffend. Recent research suggests that child pornography offending is a valid and perhaps independent indicator of pedophilia. In this study, we examined whether child pornography offending would add to the criterion-related validity of the SSPI. In the construction sample of 950 offenders with child victims, the SSPI with a fifth item of child pornography (Screening Scale for Pedophilic Interests-2 [SSPI-2]) was significantly associated with phallometrically assessed sexual arousal to children. In a validation sample of 950 offenders with child victims, the SSPI-2 was again related to phallometrically assessed sexual arousal to children, outperforming the original SSPI. We recommend clinicians and researchers use the SSPI-2 as a structured method of assessing pedophilic sexual interests based on offending behavior.

In a recent study of personal robbery, commissioned by the Home Office in the UK, a qualitative typology of robbery offences was proposed based on the approach used by the offender to commit the crime, consisting of four approach types: Blitz, Confrontation, Con, and Snatch. Conceptual inspection of the typology reveals that these proposed types may be hypothetically demarcated as the product of two latent dimensions: interaction (between the offender and the victim) and violence (used to threaten/harm the victim). The current paper utilises crime scene information from 72 incarcerated male offenders convicted of 'street' robbery to test this hypothesis. Convergent statistical analysis was utilised to test the structure of Smith's typology first using multidimensional scaling (MDS) and then principal component analysis (PCA). MDS and PCA analyses provided convergent support for the existence of the four robbery styles and the latent dimensions of interaction and violence. Implications of Smith's typological structure and latent behavioural dimensions on the conceptualisation and classification of robbery offences are discussed within the existing literature on 'street' robbery.

Many individuals with sexual interest in children express a desire for mental health services but represent an underserved client population. An identified barrier to service provision is mandatory reporting legislation, which requires clinicians to report when they learn of a child who has been, or is at risk of being, sexually abused. We conducted a vignette study to examine the factors that would influence mandatory reporting decision-making when a client discloses sexual interest in children. We recruited a convenience sample of 309 Canadian registered mental health clinicians and student trainees who completed several questionnaires. Clinicians were randomized to one of nine vignettes that were crossed on two situational factors (use of child sexual exploitation material and access to children). The results of the multivariate analysis suggested that stigma towards people with sexual interest in children was associated with an increased likelihood of reporting. Clinicians were more likely to indicate that they would report the hypothetical client was viewing child sexual exploitation material and/or had access to children. These findings are discussed within the context of improving service provision to the underserved population of people with sexual interest in children.

Individuals with a sexual interest in children who have not committed a sexual offense are a client population that are currently underserved by psychologists. In the context of accessing and providing mental health services, mandatory reporting laws represent a key issue for clients and psychologists. For clients, mandatory reporting requirements creates a double-bind: They wish to access psychotherapy for a myriad of psychological concerns, yet they fear the implications of psychologists' mandated reporting requirements if they disclose their sexual interest. Psychologists treating nonoffending clients with sexual interests in children face several overlapping and competing ethical and legal obligations created by mandatory reporting laws. To examine these complexities, the present article reviews and discusses legislation in Canada, complaints to provincial professional colleges, and case law related to mandatory reporting requirements. We additionally review principles and standards in the Canadian Psychological Association's Code of Ethics (4th ed.) to inform service provision with these clients. Recommendations for practice are provided based on this discussion, and practice case vignettes are given to facilitate ethical decision-making.

Victim choice polymorphism refers to victim inconsistency in a series of offenses by the same perpetrator, such as in the domains of victim age, victim gender, and victim-offender relationship. Past studies have found that victim age polymorphic offenders have higher rates of sexual recidivism than offenders against adults only and offenders against children only. Few studies, however, have examined gender and relationship polymorphism, or accounted for the impact of the number of past victims. The present study analyzed the relationship between polymorphism and sexual recidivism, while controlling for the number of victims. The sample consisted of 751 male adult sexual offenders followed for an average of 10 years, 311 of whom were polymorphic (41% of the total sample). The main finding suggested that there was an association between sexual recidivism and age and relationship polymorphism; however, these associations were no longer significant after controlling for the number of victims.
