Individuals with pedophilia are considered to have an elevated risk for child sexual abuse (CSA). Nevertheless, it is assumed that pedophilic sexual impulses can be controlled from acting out. To prevent CSA an outpatient treatment facility for people with pedophilia was founded in Zurich, Switzerland in 2021.

The Static-99, Static-99R, and STABLE-2007 are internationally well-established instruments for predicting static and dynamic risks of sexual recidivism in individuals convicted of sexual offenses. Previous meta-analyses assessed their predictive and incremental validity, but none has yet compared the two Static versions and the Static-STABLE combinations. Here, we implemented diagnostic test accuracy network meta-analysis (DTA-NMA) to compare all tests and identify optimal cutoffs in one comprehensive analysis.

A subgroup of psychiatric patients are at increased risk of committing interpersonal violence, which may lead to placements in forensic-psychiatric institutions. The majority of patients treated in forensic hospitals have had contact with the general psychiatric care system years before being forensically committed due to an offence. Nevertheless, attempts to establish models related to violence prevention in general psychiatry have remained sparse.

Article Synopsis
  • The study focuses on individuals with schizophrenia spectrum disorders (SSD) who have committed sex offenses, aiming to distinguish them from those with SSD who committed violent non-sex offenses.
  • It analyzed patient records of 296 men admitted to a specialized center in Zurich, utilizing machine learning to assess 461 different variables to identify distinguishing features between the two groups.
  • The findings revealed a machine learning model that successfully differentiated offenders with 71.5% accuracy, highlighting the importance of sexual behaviors, psychopathological symptoms, and typical offense characteristics in risk assessment and treatment strategies.

Introduction: It is unclear if sexual orientation is a biological trait that has neurofunctional footprints. With deep learning, the power to classify biological datasets without an a priori selection of features has increased by magnitudes. The aim of this study was to correctly classify resting-state electroencephalogram (EEG) data from males with different sexual orientation using deep learning and to explore techniques to identify the learned distinguishing features.

The present meta-analysis is an update of the meta-analysis by Schmucker and Lösel [Campbell Syst. Rev. 2017; 13: 1-75], which synthesized evidence on sexual recidivism as an indicator of treatment effectiveness in persons with sexual offense histories.

Psychopathy is associated with severe deviations in social behavior and cognition. While previous research described such cognitive and neural alterations in the processing of rather specific social information from human expressions, some open questions remain concerning central and differential neurocognitive deficits underlying psychopathic behavior. Here we investigated three rather unexplored factors to explain these deficits, first, by assessing psychopathy subtypes in social cognition, second, by investigating the discrimination of social communication sounds (speech, non-speech) from other non-social sounds, and third, by determining the neural overlap in social cognition impairments with autistic traits, given potential common deficits in the processing of communicative voice signals.

Background: A pandemic of loneliness is hitting the aging population. As COVID19 forced us to isolate ourselves, we are in a better position to understand consequences of social distancing. The recent literature showed that older incarcerated adults are particularly at risk of health-related complications due to isolation in the prison environment, reducing their social capital.

Background: Mental health professionals (MHP) working in court-mandated treatment settings face ethical dilemmas due to their dual role in assuring their patient's well-being while guaranteeing the security of the population. Clear practical guidelines to support these MHPs' decision-making are lacking, amongst others, due to the ethical conflicts within this field. This qualitative interview study contributes to the much-needed empirical research on how MHPs resolve these ethical conflicts in daily clinical practice.

A promising line of research on forensic assessment of paraphilic sexual interest focuses on behavioral measures of visual attention using sexual stimuli as distractors. The present study combined event-related potentials (ERPs) with behavioral measures to investigate whether detection of a hidden sexual preference can be improved with ERPs. Normal variants of sexual orientation were used for a proof-of-concept investigation.

Previous studies have linked polymorphisms of the monoamine oxidase A (MAOA uVNTR) and serotonin transporter gene (5-HTTLPR) to individual differences in the expression of psychopathic traits, but findings remain inconsistent. One possible reason is that these studies have treated psychopathy as a unitary construct when there is accumulating evidence that there are variants or subtypes. We used a variable-centered and a person-centered approach by (a) examining putative genetic correlates of psychopathy across individuals and (b) comparing the frequencies of the MAOA uVNTR genotype and 5-HTTLPR/rs25531 haplotype between empirically derived subtypes of psychopathy, respectively.

Background: There is limited research with inconsistent findings on differences between female and male offender patients with a schizophrenia spectrum disorder (SSD), who behave aggressively towards others. This study aimed to analyse inhomogeneities in the dataset and to explore, if gender can account for those.

Methods: Latent class analysis was used to analyse a mixed forensic dataset consisting of 31 female and 329 male offender patients with SSD, who were accused or convicted of a criminal offence and were admitted to forensic psychiatric inpatient treatment between 1982 and 2016 in Switzerland.

Protecting the human rights is particularly important within the forensic context because patients in forensic psychiatry are not admitted voluntarily and so the treatment itself is of a coercive nature. Coercive measures (, actions against the will of the patient such as forced medication, seclusion or restraint) form an additional incision of personal rights. Although the use of coercion within forensic psychiatric institutions remains controversial, little empirical research has been conducted on the use of coercive measures within forensic settings.

Depression and Violence: A Contradiction? Depression is one of the leading diseases worldwide. Its symptoms are of great importance for a variety of areas within internal medicine, as patients often pay a visit to their general practitioners first. Although symptoms of depression are observed in both genders, existing peculiarities of the symptoms in men are only insufficiently known or acknowledged.

Many reviews on sexual arousal in humans focus on different brain imaging methods and behavioral observations. Although neurotransmission in the brain is mainly performed through electrochemical signals, there are no systematic reviews of the electrophysiological correlates of sexual arousal. We performed a systematic search on this subject and reviewed 255 studies including various electrophysiological methods.

Formal thought disorders are common in people diagnosed with schizophrenia. Among them, concretism stands for deficiencies in the understanding of idiomatic expressions, metaphors and proverbs. However, little is known as to whether concretism is a correlate of the acuteness or severity of schizophrenia within patients.

Psychopathy is characterized by callous affect, interpersonal manipulation, a deviant lifestyle, and antisocial behavior. Previous research has linked psychopathic traits to childhood trauma, but also to the upstream variable number tandem repeat (uVNTR) polymorphism of the monoamine oxidase A (MAOA) gene. An interaction between childhood trauma and MAOA genotype has been associated with antisocial behavior, but so far little is known about interaction effects of childhood trauma and the MAOA uVNTR on psychopathy.

Psychopathy is characteristically associated with deficits in emotion perception; however, findings surrounding this deficit are actually quite mixed. This is most likely due to limitations of study methodology, including the use of tasks with unknown or poor psychometric properties, underpowered samples, and a lack of control for third variables. We present a study that addressed these limitations.

Psychiatric and psychological diagnoses are imperfect. Unlike somatic medicine, most psychological and psychiatric phenomena have no gold standard to establish their presence beyond reasonable doubt. Consequently, prevalence estimates are based on the average agreement of imperfect evaluators.
