SUMMARYSexual and relationships difficulties are not uncommon among psychiatric patients. A presenting complaint of anxiety or depression may relate to an underlying sexual or relationship difficulty; commonly used psychotropic medications cause sexual side-effects that can have a significant impact quality of life, relationship maintenance and treatment adherence; patients may exhibit unusual or excessive sexual behaviours when acutely unwell, including risky use of apps to meet sexual partners and accessing online pornography in unsafe ways; patients may have used technology such as the internet to harm others or they may be victims of such harm; the internet and social media might even be influencing sexual expression, for example gender identity. Therefore, psychosexual history-taking remains a key competency for psychiatrists. They must also understand the new language used to describe sexuality, sexual behaviours and the use of social media, apps and so on to form relationships. This article outlines the key areas to consider in carrying out a structured psychosexual assessment. It also gives an overview of current sexual terminology, observed influences of the internet on sexuality and sexual behaviour, and its implications for mental health and potential sexual offending.LEARNING OBJECTIVESAfter reading this article you will be able to: •outline a framework for psychosexual history-taking•recognise emerging terminology relating to sexual behaviours and identity•understand the relevance of the internet, social media and technology-based apps to human relationships, including the use of technology in sexual offendingDECLARATION OF INTERESTNone.

Development And Validation

Tools designed to measure the cognitions of individuals who engage in sexual activities with children over the Internet are either based on knowledge about men who had committed contact sexual offenses or cognitive phenomena not specifically associated to offending behaviors. Thus, there is no validated tool specifically designed to assess the offense-supportive cognitions of men who use the Internet to sexually offend children. This study developed and validated the Cognitions of Internet Sexual Offending (C-ISO) scale. A sample of 241 men with online and contact sexual as well as with nonsexual offenses completed the C-ISO scale and its psychometric properties, and latent structure was analyzed using both Classical Test Theory (CTT) and Item Response Theory (IRT), resulting in a final version containing 31 items. The analyses indicate that the C-ISO has excellent psychometric properties and discriminates men with online sexual offenses from those with contact sexual and nonsexual offenses. Implications of the findings for clinical practice and future research are discussed.

Two Sided Markets

In this paper, we present a new model and mechanisms for auctions in two-sided markets of buyers and sellers, where budget constraints are imposed on buyers. Our model incorporates polymatroidal environments and is applicable to a variety of models that include multiunit auctions, matching markets, and reservation exchange markets. Our mechanisms are built on the polymatroidal network flow model by Lawler and Martel. Additionally, they feature nice properties such as the incentive compatibility of buyers, individual rationality, Pareto optimality, and strong budget balance. The first mechanism is a two-sided generalization of the polyhedral clinching auction by Goel et al. for one-sided markets. The second mechanism is a reduce-to-recover algorithm that reduces the market to be one-sided, applies the polyhedral clinching auction by Goel et al., and lifts the resulting allocation to the original two-sided market via the polymatroidal network flow. Both mechanisms are implemented by polymatroid algorithms. We demonstrate how our framework is applied to the Internet display advertisement auctions.

Criminal Behaviors

There is evidence that endorsing a higher level of offense-supportive cognitions is associated with contact sexual offending. Such an association assumes the construct of cognitions as unidimensional, thus ignoring the possibility that specific subtypes of cognitions exist and that certain may be criminogenic. To investigate this possibility, this study aimed at examining the associations between criminal behaviors and cognitive themes found in the discourse of men who engage in sexual offenses against children over the Internet. Through the discourse of a sample of 60 men with online child sexual exploitation material and solicitation offenses, a previous study identified eight cognitive themes: Uncontrollability, Nature of harm, Child as sexual being, Child as partner, Dangerous world, Entitlement, Virtual is not real, and Internet is uncontrollable. These themes were not investigated for their criminogenic nature. Thus, in this study, bivariate analyses were used to determine whether these cognitive themes were linked to three indicators of criminal behaviors: the extent of criminal charges, the diversity of offending behaviors, and the nature of contact with victims. Results suggest that, taken as a whole, online sexual offense–supportive cognitions may not be criminogenic. Moreover, only cognitive themes related to antisocial orientation and atypical sexuality were found linked with criminal behaviors, although associations found remain limited. Findings and associated implications are further discussed for research and clinical purposes.

Behavioral Markers

While forensic psychologists have some access to their patients’ thoughts when deciding on a diagnosis or appraising risk, others, such as police investigators, must rely on physical evidence and behavioral markers to make sense of a crime. Studies showing that offense-supportive cognitions constitute a risk factor for sexual offending, including offenses that take place on the internet, highlight the need for some access to offenders’ thoughts. This exploratory study examines the associations between offense-supportive statements about the sexual exploitation of children and adolescents and proxy behaviors. As part of PRESEL, a collaborative research project between Québec provincial police and academic researchers, the case files of 137 men convicted of using child sexual exploitation material or committing child-luring offenses were analyzed. Results showed that many meaningful risk factors and sexual offending behavioral markers were associated with the cognitive themes Sexualization of children, Child as partner, Dangerous world, Entitlement, and Uncontrollability. The use of encryption was negatively associated with the cognition Virtual is not real while Internet is uncontrollable was associated with fewer contacts with minors over the internet. Findings are useful for understanding the psychological needs that should be targeted in treatment, as well as helping prioritize police workloads.
