An out-of-court community-based programme to improve the health and well-being of young adult offenders: the Gateway RCT.

Background: Young adults represent a third of the United Kingdom prison population and are at risk of poor health outcomes, including drug and alcohol misuse, self-harm and suicide. Court diversion interventions aim to reduce the negative consequences of criminal sanctions and address the root causes of offending. However, evidence of their effectiveness has not yet been established. The Gateway programme, issued as a conditional caution, aimed to improve the life chances of young adults committing low-level offences. Participants agreed not to reoffend during the 16-week caution and, following a needs assessment, received individual support from a Gateway navigator and attended two workshops encouraging analysis of own behaviour and its consequences. Objective: To evaluate the effectiveness and cost-effectiveness of Gateway in relation to health and well-being of participants compared to usual process (court summons or a different conditional caution). Design, setting and participants: Pragmatic, multisite, parallel-group, superiority randomised controlled trial with two 6-month internal pilots and a target sample size of 334. Randomisation between Gateway and usual process was on a 1 : 1 basis. Four Hampshire Constabulary sites recruited 18- to 24-year-old residents of Hampshire and Isle of Wight who were questioned for an eligible low-level offence. Semistructured interviews were also held with a sample of Gateway programme participants, staff and police study recruiters. Main outcome measures: Primary outcome was the Warwick-Edinburgh Mental Wellbeing Scale score at 12 months. Secondary outcomes included health status, alcohol and drug use, recidivism and resource use. Results: Recruitment commenced in October 2019 and the trial stopped in April 2021. A total of 191 participants were recruited, with 109 randomised to Gateway and 82 to usual process. Due to an initial overestimation of potentially eligible young people and low retention rates, recruitment targets were adjusted, and a range of mitigating measures introduced. Although recruitment broadly met study progression criteria [35/50 (70%) Pilot 1: 64/74 (86%) Pilot 2], retention was low throughout (overall: data collected at week 4 was 50%: at week 16 it was 50%: 1-year 37%). Low retention was multifactorial, with one of the main barriers being difficulties contacting participants. It was therefore not possible to complete the randomised controlled trial or the health economics analyses. Qualitative interviews held with 58 individuals yielded rare insights into the benefits and limitations of this type of intervention, as well as barriers and facilitators in relation to recruitment in this setting. Limitations: Despite close collaboration with the police to address recruitment and consent issues, expansion of the inclusion criteria and recruitment area and introducing other measures, the researchers were unable to collect sufficient data within an acceptable timeframe. Conclusions: The Gateway study was a unique endeavour to gather evidence for a potentially life-changing intervention for an underserved population. The experience gained indicates that randomised controlled trials of interventions, with a health-related outcome, are possible in this setting but point towards the need for conservative recruitment and retention estimates in this target population. Other study designs should be considered. The qualitative evaluation provided a range of valuable lessons for those seeking to design similar interventions or conduct research in similar settings. Study registration: This study is registered as ISRCTN11888938.

Young adults who commit low-level offences often have many health and social needs, making them vulnerable to physical and mental health problems. The Gateway programme was a conditional caution developed to address the underlying causes of low-level offending in young people aged 18­24 years and hence improve their life chances. In Gateway, a mentor assessed the young person's needs and supported them, signposting to healthcare, housing or other services as required. The young people also participated in two workshops, analysing the causes and consequences of their behaviour. To find out if Gateway improved health and reoffending rates, a group of those who received a Gateway conditional caution were compared with a group of those receiving a court summons or a different conditional caution. Of the 191 participants recruited to the study, 109 were randomised to Gateway and 82 to the usual process. However, the researchers had significant difficulties getting hold of the study participants on the phone and they were unable to collect enough information from them to be able to say whether Gateway worked. The researchers introduced various changes to overcome this, but in the end had to stop the study early. As part of the study, the researchers interviewed 28 Gateway programme participants, 17 Gateway project staff and 13 police officers and staff who had been recruiting into the study. From the interviews the study discovered the perceived benefits of Gateway, how programmes like this could be improved and which factors helped or got in the way of doing research in the police setting. The Gateway study aimed to provide evidence for a potentially life-changing intervention for vulnerable young adults. Although it proved impossible to complete the study, the lessons learnt from running it should help colleagues design similar programmes or plan research studies with similar populations or in similar settings.

Childhood maltreatment and subsequent offending behaviors in Australian women: Exploring the role of borderline personality disorder.

BACKGROUND: Childhood Maltreatment (CM) is linked to adverse outcomes, including Borderline Personality Disorder (BPD) and increased propensity for offending behaviors. However, research on the specific role that BPD plays between the two is limited and highly relevant given the high prevalence of CM in Australia. OBJECTIVE: The present study aimed to investigate (1) the relationship between CM and subsequent offending behaviors, (2) whether BPD mediates the relation between CM and offending behaviors, and (3) which type of CM (physical, sexual, emotional abuse, neglect, exposure to domestic violence, multitype maltreatment) predicts BPD. PARTICIPANTS: The sample comprised 106 self-identified Australian female survivors of interpersonal violent crimes. METHODS: Participants completed an online survey consisting of the Adverse Childhood Events Questionnaire, the McLean Screening Instrument for BPD, and a self-created questionnaire to measure offending behaviors. Regression, mediation analysis, and logistic regression were conducted. RESULTS: CM significantly predicted offending behaviors (path c, B = 1.39, p <. 001) with BPD partially mediating the relationship (path c', B = 1.04, 95 % CI [0.31, 1.77], p = .006; path a, B = 0.47, 95 % CI [0.12, 0.83], p = .009, path b, B = 0.34, 95 % CI [0.07, 0.61], p = .014). Emotional abuse and multitype exposure were identified as predictors of BPD symptom development (OR = 9.42, 95 % CI OR [2.58, 34.40]; OR = 3.81, 95 % CI OR [1.41; 10.28], respectively). CONCLUSION: These findings indicate the necessity of early interventions addressing CM, with a particular focus on emotional abuse and exposure to more than one type of maltreatment, to reduce the risk of developing BPD symptomatology and mitigate future offending behaviors.

Access to Care and Outcomes With the Affordable Care Act for Persons With Criminal Legal Involvement: A Scoping Review.

Importance: By expanding health insurance to millions of people in the US, the Patient Protection and Affordable Care Act (ACA) may have important health, economic, and social welfare implications for people with criminal legal involvement-a population with disproportionately high morbidity and mortality rates. Objective: To scope the literature for studies assessing the association of any provision of the ACA with 5 types of outcomes, including insurance coverage rates, access to care, health outcomes, costs of care, and social welfare outcomes among people with criminal legal involvement. Evidence Review: The literature search included results from PubMed, CINAHL Complete, APA Psycinfo, Embase, Social Science Database, and Web of Science and was conducted to include articles from January 1, 2014, through December 31, 2023. Only original empirical studies were included, but there were no restrictions on study design. Findings: Of the 3538 studies initially identified for potential inclusion, the final sample included 19 studies. These 19 studies differed substantially in their definition of criminal legal involvement and units of analysis. The studies also varied with respect to study design, but difference-in-differences methods were used in 10 of the included studies. With respect to outcomes, 100 unique outcomes were identified across the 19 studies, with at least 1 in all 5 outcome categories determined prior to the literature search. Health insurance coverage and access to care were the most frequently studied outcomes. Results for the other 3 outcome categories were mixed, potentially due to heterogeneous definitions of populations, interventions, and outcomes and to limitations in the availability of individual-level datasets that link incarceration data with health-related data. Conclusions and Relevance: In this scoping review, the ACA was associated with an increase in insurance coverage and a decrease in recidivism rates among people with criminal legal involvement. Future research and data collection are needed to understand more fully health and nonhealth outcomes among people with criminal legal involvement related to the ACA and other health insurance policies-as well as the mechanisms underlying these relationships.

How Should a Medical-Legal Partnership Address Unique Needs of People With Criminal Legal System Involvement?

Medical-legal partnerships (MLPs) are well suited to address health-harming legal needs associated with the collateral consequences of mass incarceration in the United States, such as those that limit access to food, housing, employment, and family reunification postrelease. MLP innovations seek to expand the current model to address patients' criminal, as well as postrelease, civil legal needs by including community health workers and some patients as legal partners and creating coalitions to promote local and state policy change. Overall, this article explains how these MLP innovations can support rights of people returning to communities after incarceration and can be leveraged to mitigate criminal legal system involvement.

Dark and bright personality dimensions as predictors of criminal behavior and recidivism.

A growing body of research highlights the continuum between dark and bright personality traits impacting individual prosocial or antisocial tendencies. However, the interplay between personality dimensions and actual criminal behavior and its reoccurrence is not fully elucidated. We aimed to explore the cumulative predictive value of the bright and dark core of personality for criminal history in differentiating a general community sample (N = 282) from a large sample of inmates (N = 296), with (n = 129) or without (n = 167) criminal history while controlling for age, sex and impression management. Predictors of first-time offending were higher levels of Neuroticism, Openness, Dark Factor, Sadism, and Deceitfulness. Criminal recidivism was predicted by high Neuroticism and Deceitfulness. Finally, higher levels of Extraversion were negatively related to criminal behavior and history, highlighting a potential protective effect of displaying assertive and sociable tendencies. The findings highlight the relevance of considering the dark personality core complementary to the typical personality dimensions in the risk assessment, prediction, and reduction of criminal behavior.

[Taking care of minor offenders: between methodological practices and experience.] / La presa in carico dei minori autori di reato: tra prassi metodologiche ed esperienza.

To fully respond to the provisions of the Judicial Authority relating to the care of minors and/or young adults subjected to judicial measures and affected by mental suffering and/or substance abuse, also with a view to a possible provision of placement in a therapeutic community, the UOSD "Protection of the Health of Adults and Minors in the Penal Area" - ASL Salerno has ensured operations through the establishment of a dedicated multidisciplinary team, made up of a psychiatrist, psychologist and social worker, as required by DGRC 567/2018, or as the only interface with the Judicial Authority in reference to healthcare. This article aims to describe the birth of the EMM (Equipe Multidisciplinare Minori), and of the methods used to take care of minors and/or young adult offenders affected by mental suffering and/or substance abuse. The article examines a sample of 207 minors, relating to the years 2018-2022, to highlight the most critical areas.

Network analysis of trait aggression among community youths and juvenile offenders.

OBJECTIVE: The mainstream view in trait aggression research has regarded the structure as representing the latent cause of the cognitions, emotions, and behaviors that supposedly reflect its nature. Under network perspective, trait aggression is not a latent cause of its features but a dynamic system of interacting elements. The current study uses network theory to explain the structure of relationships between trait aggression features in juvenile offenders and their peers. METHODS: Network analysis was applied to investigate the dynamic system of trait aggression operationalized by the Buss-Perry Aggression Questionnaire in a sample of community youths (Mage = 17.46, N = 715) and juvenile offenders (Mage = 18.36, N = 834). RESULTS: The facet level networks showed that anger is a particularly effective mechanism for activating all other traits. In addition, anger was more strongly associated with physical aggression and the overall network strength was greater in juvenile delinquency networks than in their peers. The item level networks revealed that A4 and A6 exhibited the highest predictability and strength centrality in both samples. Also, the Bayesian network indicated that these two items were positioned at the highest level in the model. There are similarities and differences between juvenile delinquents and community adolescents in trait aggression. CONCLUSION: Trait aggression was primarily activated by difficulty controlling one's temper and feeling like a powder keg.

The role of truth in victim-offender mediation: Victims of crime who feel they know the "whole" truth are more receptive to apologies.

OBJECTIVE: We conducted three preregistered studies to examine whether victims of crime are more receptive to apologies in victim-offender mediation if they feel they know the "whole" truth about a crime. HYPOTHESES: We predicted that making salient the completeness (vs. incompleteness) of knowledge about a crime would lead victims to (a) have a greater sense of truth knowing and (b) view an apology more favorably. METHOD: Participants in Study 1 (N = 380; Mage = 41.2 years; 51% men; 78% White) and Study 2 (N = 550; Mage = 41.0 years; 65% women; 72% White) imagined being the victim of cybercrime. Participants in Study 3 (N = 670; Mage = 42.7 years; 52% men; 72% White) were real crime victims. Participants imagined taking part in victim-offender mediation during which the offender apologized, and then they evaluated the apology after answering questions that made salient what they either knew or did not know about the crime (complete knowledge salience vs. incomplete knowledge salience). Participants in Study 2 received additional information about the crime from either the offender or the police to test whether truth source acts as a moderator. RESULTS: Participants in the complete (vs. incomplete) knowledge salience condition reported greater truth knowing (Study 1 d = 1.40, Study 2 d = 1.26, Study 3 d = 0.58), readiness for an apology (Study 1 d = 0.25; Study 2 d = 0.23; Study 3 d = 0.09, nonsignificant), perceived completeness of an apology (Study 1 d = 0.26, Study 2 d = 0.31, Study 3 d = 0.19), and acceptance of an apology (Study 1 d = 0.22; Study 2 d = 0.21; Study 3 d = 0.10, nonsignificant). In Study 2, truth source moderated the effect only on apology acceptance (η2 = .009). Across the three studies, complete (vs. incomplete) knowledge salience was indirectly positively related to apology readiness, apology completeness, and apology acceptance (nonsignificant in Study 3), via truth knowing. CONCLUSIONS: Instances of victim-offender mediation should ensure that victims' need for truth is satisfied because this may increase the effectiveness of apologies.

Validation of the Revised Screening Scale for Pedophilic Interests (SSPI-2) in Portugal.

The accurate assessment of pedophilic sexual interests is crucial for the treatment and management of individuals who have sexually offended children. This study aimed to validate the Revised Screening Scale for Pedophilic Interests (SSPI-2) in a Portuguese sample of 170 men convicted of sexual offenses against children, 104 serving sentences in the community, and 66 in prison. The findings indicated that SSPI-2 demonstrated good convergent validity, as evidenced by its significant and positive associations with the "sexual deviance" item of SVR-20, the number of previous convictions for sexual crimes against children, and having 3 or more child victims, which is associated with high sensitivity and specificity in distinguishing men who show greater sexual arousal to children than to adults. Furthermore, the SSPI-2 exhibited good divergent validity, with no significant correlations observed with a self-report measure of psychopathy or with a nonsexual criminal history.

Aberrant type 2 dopamine receptor availability in violent offenders with psychopathy.

Psychopathy is characterized by antisocial behavior, poor behavioral control and lacking empathy, and structural alterations in the corresponding neural circuits. Molecular brain basis of psychopathy remains poorly characterized. Here we studied type 2 dopamine receptor (D2R) and mu-opioid receptor (MOR) availability in convicted violent offenders with high psychopathic traits (n = 11) and healthy matched controls (n = 17) using positron emission tomography (PET). D2R were measured with radioligand [11C]raclopride and MORs with radioligand [11C]carfentanil. Psychopathic subjects had lowered D2R availability in caudate and putamen, and striatal D2R availability was also associated with degree of psychopathic traits in this prisoner sample. No group differences were found in MOR availability, although in the prisoner sample, psychopathic traits were negatively correlated with MOR availability in the amygdala and nucleus accumbens. We conclude that D2R signaling could be the putative neuromolecular pathway for psychopathy, whereas evidence for alterations in the MOR system is more limited.

Accessing child sexual abuse material: Pathways to offending and online behaviour.

BACKGROUND: Most research examining the consumption of online child sexual abuse material (CSAM) has focused on offenders' demographic and psychological characteristics. While such research may assist in the development of therapeutic interventions with known offenders, it has little to offer the development of interventions for the vast majority of offenders who are never caught. OBJECTIVE: To learn more about the offending strategies of CSAM offenders, in order to inform prevention efforts to deter, disrupt, and divert individuals from their pursuit of CSAM. PARTICIPANTS & SETTING: Seventy-five male CSAM offenders, who were living in the community and were voluntarily participating in a treatment programme. METHODS: Participants completed a detailed self-report questionnaire focussing on their pathways to offending and their online behaviour. RESULTS: Most participants reported that they did not initially seek out CSAM but that they first encountered it inadvertently or became curious after viewing legal pornography. Their involvement in CSAM subsequently progressed over time and their offending generally became more serious. The most notable feature of participants' online behaviour was the relative lack of sophisticated technical expertise. Opportunity and other situational factors emerged as mediators of offending frequency. Offending patterns were affected by participants' psychological states (e.g., depression, anger, stress), offline relationships and commitments (e.g., arguments with spouse, loss of job), and online experiences (e.g., blocked sites, viruses, warning messages). CONCLUSIONS: Findings suggest that many offenders are receptive to change and may be potentially diverted from their offending pathway.

Are you a cop?: Identifying suspicion in online chat operations with online groomers.

BACKGROUND: The increase in online enticement has led to law enforcement agencies engaging in more proactive policing through undercover chat sting operations. OBJECTIVE: We aimed to identify the topics and communication strategies triggering suspicion in chats between law enforcement officers and offenders and why those topics do not result in suspicion in victim-offender conversations. METHODS: We conducted a thematic analysis identifying: (1) how LEOs trigger suspicion, (2) how offenders communicate suspicion, (3) how LEOs attempt recovery from suspicion, and (4) how these triggers were present but did not trigger suspicion in victim-offender chats. We examined 20 LEO-offender chats and 20 victim-offender chats from US ICAC task forces. RESULTS: We identified four themes that triggered suspicion: risk assessment by the LEO's persona, LEO avoidance measures, details related to the offense and evidence, and proof of identity of chat participants. Offender responses to triggers revealed three themes: discomfort navigating boundaries and uncertainty, risk identification, and risk mitigation. Themes for the LEO's responses to suspicion included: risk assessment for chatters, issues with technology, appeasement, and negative emotional reactions. Finally, juxtaposing triggers onto minor-offender chats yielded four themes: explicit boundary setting, victim risk assessment, deep relationship forming and disclosures, and technology issues. CONCLUSION: This study has implications for law enforcement agencies seeking to reduce suspicion and risk assessment by offenders during internet sting operations.

Predictors of Criminal Sentiments Scale-Modified Scores in Outpatients with Legal System Involvement.

The Criminal Sentiments Scale-Modified (CSS-M) has been widely used as a measure of criminal attitudes. This analysis examined CSS-M scores in a large sample of outpatients with serious mental illnesses and a criminal legal system history. We compared total and subscale scores in our sample to scores from two other previously published U.S. studies in which the CSS-M was used, and evaluated associations between total CSS-M score and nine variables (age, educational attainment, gender, race, marital status, employment status, diagnostic category, substance use disorder comorbidity, and adverse childhood experiences (ACE) score). Scores were higher than in two prior U.S. studies involving other types of samples. Independently significant predictors of higher CSS-M scores included being younger (P < .001), having a higher ACE score (P < .001), being male (P = 03), not identifying as White (P < 001), not having a psychotic disorder (P < 001), and having a comorbid substance use disorder (P = 002). Future research should test the hypothesis that these factors increase risk for arrest and that arrest events, and subsequent criminal legal system involvement, are characterized by negative experiences and perceptions of poor procedural justice, which in turn underpin the negative opinions referred to as "criminal sentiments" or criminal attitudes.

Buprenorphine-naloxone vs. extended-release naltrexone for opioid use disorder in individuals with and without criminal legal involvement: A secondary analysis of the X:BOT randomized controlled trial.

INTRODUCTION: There is uncertainty about whether criminal legal involvement (CLI) impacts the effectiveness of medications for opioid use disorder (MOUD). We aimed to determine whether CLI modifies the association between buprenorphine-naloxone (BUP-NX) vs. extended-release naltrexone (XR-NTX) and MOUD treatment outcomes. METHODS: We conducted a secondary analysis of X:BOT, a 24-week multi-center randomized controlled trial comparing treatment outcomes between BUP-NX (n = 287) and XR-NTX (n = 283) in the general population. We used baseline Additional Severity-Index Lite responses to identify patients with recent CLI (n = 342), defined as active CLI and/or CLI in the past 30 days, and lifetime incarceration (n = 328). We explored recent CLI and lifetime incarceration as potential effect modifiers of BUP-NX vs. XR-NTX effectiveness on relapse, induction, and overdose. We conducted both intention-to-treat and per-protocol analyses for each outcome. RESULTS: In intention-to-treat analyses, recent CLI modified the effect of BUP-NX vs. XR-NTX on odds of successful induction (p = 0.03) and hazard of overdose (p = 0.04), but it did not modify the effect on hazard of relapse (p = 0.23). All participants experienced lower odds of successful induction with XR-NTX compared to BUP-NX, but the relative likelihood of successful induction with BUP-NX was lower than XR-NTX among individuals with recent CLI (OR: 0.25, 95 % CI: 0.13-0.47, p < 0.001) compared to those without recent CLI (OR: 0.04, 95 % CI: 0.01-0.19, p < 0.001). Participants with recent CLI experienced similar hazard of overdose with XR-NTX and BUP-NX (HR: 1.12, 95 % CI: 0.42-3.01, p = 0.82), whereas those without recent CLI experienced greater hazard of overdose with XR-NTX compared to BUP-NX (HR: 12.60, 95 % CI: 1.62-98.03, p = 0.02). In per-protocol analyses, recent CLI did not modify the effect of MOUD on hazard of overdose (p = 0.10) or relapse (p = 0.41). Lifetime incarceration did not modify any outcome. CONCLUSIONS: Compared to individuals without recent CLI, individuals with recent CLI experienced decreased relative effectiveness of BUP-NX compared to XR-NTX for induction and overdose outcomes. This highlights the importance of considering the impact of recent CLI on opioid use disorder treatment outcomes. Future research should explore the mechanisms through which recent CLI modifies MOUD effectiveness and aim to improve MOUD effectiveness for individuals with recent CLI.

Predictors of psychosocial functioning in people diagnosed with schizophrenia spectrum disorders that committed violent offences and in those that did not: Results of the Recoviwel study.

Psychosocial functioning represents a core treatment target of Schizophrenia Spectrum Disorders (SSD), and several clinical and cognitive factors contribute to its impairment. However, determinants of psychosocial functioning in people living with SSD that committed violent offences remain to be more thoroughly explored. This study aims to separately assess and compare predictors of psychosocial functioning in people with SSD that did and that did not commit violent offences considering several clinical, cognitive and violence-related parameters. Fifty inmates convicted for violent crimes in a forensic psychiatry setting diagnosed with SSD (OP group) and fifty participants matched for age, gender, education, and diagnosis (Non-OP group) were included in the study. A higher risk of violent relapse as measured by HCR-20 clinical subscale scores (p < 0.002) and greater global clinical severity as measured by CGI-S scores (p = 0.023) emerged as individual predictors of worse psychosocial functioning, as measured by PSP scores, in the OP group. Greater global clinical severity (p < 0.001), worse performance in the processing speed domain as measured by the BACS Symbol Coding (p = 0.002) and TMT-A tests (p = 0.016) and higher levels of non-planning impulsivity as measured by BIS-11 scores (p < 0.001) emerged as individual predictors of worse psychosocial functioning in the Non-OP group. These results confirm that clinical severity impacts psychosocial functioning in all individuals diagnosed with SSD and suggest that while cognitive impairment clearly represents a determinant of worse functional outcomes in most patients, the risk of violent relapse is a specific predictor of worse psychosocial functioning in people with SSD that committed criminal offences.

Eligible offender samples are missing in CODIS: A statewide approach to performing a lawfully owed DNA census.

In 2019, the Texas Department of Public Safety (TXDPS) Texas Ranger Division (TRD) identified approximately 3300 registered sex offenders (RSOs) from whom a "lawfully owed" DNA sample was missing from the Federal Bureau of Investigation's Combined DNA Index System (CODIS). Lawfully owed DNA (LODNA) is defined as a DNA sample from a qualifying offender who should have had their sample entered into CODIS, but for unknown reasons did not. As a result of those findings, TXDPS then applied for and was awarded a grant from the Bureau of Justice Assistance's Sexual Assault Kit Initiative to collect DNA specimens from these RSOs, and to perform a statewide LODNA census. TXDPS TRD sought to determine: Are the missed DNA collection problems limited to RSO's or are they occurring among individuals with a qualifying arrest or conviction as specified by state law too? What processes are used to identify individuals who are eligible for DNA sample collection? How is an individuals' DNA collection eligibility conveyed to external agencies? The findings from TXDPS' LODNA census, identified 43,245 individuals who were likely eligible for DNA collection between 1995 and 2020, therefore indicating statewide DNA collection issues. Over 4 years, collection efforts pertaining to the aforementioned lawfully owed census, have yielded 5183 LODNA sample collections, and 276 CODIS hits. This manuscript aims to create an awareness within other agencies of the importance of implementing best practices to ensure the collection and upload of LODNA from every eligible individual.

Contact sex offenders with adult and minor victims: Psychopathological and criminological differences.

BACKGROUND: Effective classification of individuals who commit sexual offences is important for their assessment, treatment, and risk management. Victim age has often been used as a distinguishing factor between perpetrators. OBJECTIVE: This study aimed to analyse the distinctive psychopathological and criminological characteristics of contact sexual offenders with adult and minor victims. PARTICIPANTS AND SETTING: The study involved 97 adult males who were serving a prison sentence in Spain for at least one contact sexual offence against an adult or a minor. METHODS: Researchers gathered data on criminological variables concerning the offender, victim, and modus operandi from prison records and interviews. Participants completed the Millon Clinical Multiaxial Inventory-III (MCMI-III) in a second session, and between-group differences were analysed. RESULTS: Sex offenders with minor victims (SOMV) had significantly lower scores than sex offenders with adult victims (SOAV) on the Antisocial (r = -0.283, p = .005) and Sadistic (r = -0.209, p = .04) personality subscales, and on the Alcohol (r = -0.426, p < .001) and Drug dependence (r = -0.332, p = .001) syndrome subscales. SOAV were also more likely to use violence and/or intimidation, use a weapon, offend against female victims, offend against an intimate partner, commit their offences in public places, serve other ongoing prison sentences, and report a history of alcohol and substance abuse. SOMV were older and more likely to offend against family members. CONCLUSIONS: These results suggest that there are key differences between SOAV and SOMV that should be considered in tailored prevention programmes for each subgroup of offenders.

A multi-factor knuckle and nail bed verification tool for forensic imagery analysis.

BACKGROUND: The grooming process involves sexually explicit images or videos sent by the offender to the minor. Although offenders may try to conceal their identity, these sexts often include hand, knuckle, and nail bed imagery. OBJECTIVE: We present a novel biometric hand verification tool designed to identify online child sexual exploitation offenders from images or videos based on biometric/forensic features extracted from hand regions. The system can match and authenticate hand component imagery against a constrained custody suite reference of a known subject by employing advanced image processing and machine learning techniques. DATA: We conducted experiments on two hand datasets: Purdue University and Hong Kong. In particular, the Purdue dataset collected for this study allowed us to evaluate the system performance on various parameters, with specific emphasis on camera distance and orientation. METHODS: To explore the performance and reliability of the biometric verification models, we considered several parameters, including hand orientation, distance from the camera, single or multiple fingers, architecture of the models, and performance loss functions. RESULTS: Results showed the best performance for pictures sampled from the same database and with the same image capture conditions. CONCLUSION: The authors conclude the biometric hand verification tool offers a robust solution that will operationally impact law enforcement by allowing agencies to investigate and identify online child sexual exploitation offenders more effectively. We highlight the strength of the system and the current limitations.

Testing a hybrid risk assessment model: Predicting CSAM offender risk from digital forensic artifacts.

BACKGROUND: Recent research argues for a formalized hybrid risk assessment model that combines the current online child sex abuse risk measures with digital forensics artifacts. OBJECTIVE: We conducted a feasibility study as an initial step toward formalizing the hybrid risk assessment model by identifying high-level digital forensic artifacts that have the potential to be valid and reliable indicators of risk, with a focus on CPORT Items 5, 6, and 7. DATA: Law enforcement investigators from a High Tech Crime Unit (HTCU) randomly selected seven closed cases; selection criteria included: male offender over 18, mobile device, child sexual abuse material (CSAM) offense, and 2019-2023 index offense. Investigation details related to probable cause, final charges, conviction, and offender risk were not disclosed. Statistical information (f, %) for the following digital forensics artifacts was examined: 1) pornography collection (e.g., % of media, content type, gender ratio) and 2) evidence of networking/grooming and other problematic online activities (e.g., number of native messages vs. application messages; type of installed apps). METHOD: The analysis predicted whether the offender was a CSAM-only or dual offender and if our findings agreed with the level of risk for reoffending suggested by CPORT Items 5, 6, and 7. Results were shared with the HTCU and scored for accuracy. RESULTS: The hybrid model was accurate in 6 of 7 cases. CONCLUSION: We conclude a hybrid model is feasible, and the findings illustrate the importance of analyzing app artifacts for context. Study limitations and future research recommendations are discussed.
