Unveiling covert psychopathy: a case report utilizing the Psychopathy Checklist-Revised scale in the forensic psychiatric setting

This case report explores the diagnostic complexities and treatment challenges associated with psychopathy and antisocial personality disorder (ASPD) in a forensic psychiatric setting. Utilizing the Psychopathy Checklist-Revised (PCL-R) scale, we assessed a 29-year-old male previously detained for two attempted murders and investigated for insulting a public official. Despite a history of mood and psychotic symptoms, previous evaluations failed to identify underlying psychopathic traits. Our assessment revealed a PCL-R score of 33/40, indicating a clear picture of psychopathy. The subject exhibited aggressive and violent behaviors from childhood, including cruelty to animals and reckless actions. Diagnoses over time included attention deficit/hyperactivity disorder, bipolar disorder, and substance use disorders, reflecting significant diagnostic heterogeneity. The case underscores the importance of comprehensive psychopathy assessments in forensic contexts, particularly when previous diagnoses and treatments have been inconsistent. Our findings highlight the potential of the PCL-R scale as a valuable tool for identifying covert psychopathic traits, which are often underestimated. This study calls for further research into the diagnostic and therapeutic approaches for psychopathy and ASPD, emphasizing the need for tailored interventions in correctional institutions to mitigate the risk of recidivism.

Unraveling Relapse in Male Forensic Psychiatric Patients with Substance Use Disorders—The Impact of Social, Psychiatric, and Personality Factors Post Long-Term Remission

AbstractSubstance use disorder, labelled a chronic relapse condition by the WHO, remains challenging to address with limited progress in effective relapse prevention measures. Scientific evaluation is hindered by cost, but an opportunity arises in the German forensic psychiatric setting governed by § 64 of the German criminal code. Here, patients undergo two-year multi-modal therapy followed by up to five years of supervised oversight post-release. This retrospective study analyzed legal and medical records, revealing key determinants of relapse, including emotional stress, social activities, personality disorder diagnosis, inpatient treatment relapse, age at first conviction, and loss of motivation. Surprisingly, social factors like family and work status, living situation at discharge, and dialectical behavioral therapy during admission showed no impact, nor did index crime type. Polysubstance use, except for cannabinoids and psychostimulants other than cocaine, increased relapse probability. Multiple inpatient pretreatments were insignificant predictors. A generalized linear model highlighted substance use during inpatient treatment, personality disorder, and previous convictions as most central predictors of post-discharge relapse, challenging conventional notions and informing effective substance use disorder management.

VR-assisted aggression treatment in forensic psychiatry: a qualitative study in patients with severe mental disorders.

Improvements in virtual reality (VR) have made it possible to create realistic, virtual settings for behavioral assessment and skills training that cannot otherwise be accessed in a safe way in forensic psychiatric settings. VR interventions are under development but little is known how forensic psychiatric patients with severe mental disorders experience VR-assisted assessments or treatments. The present study aimed to help fill this knowledge gap via qualitative interviews with seven patients with severe mental disorders at a high-security forensic psychiatric clinic who had completed the newly revised Virtual Reality Aggression Prevention Training (VRAPT). All participants were interviewed 12 weeks after the VRAPT intervention, and interview data analyzed with manifest inductive content analysis. Six manifest content categories were identified: 1. Therapeutic process, 2. VRAPT method, 3. VR technology, 4. Previous treatment experiences, 5. Challenges to treatment of aggression, and 6. Unexpected experiences. The participants had diverse experiences related to both the VRAPT intervention and forensic psychiatric care. Participants described a mixture of positive experiences in relation to VR-assisted role-plays, and less positive in relation to motivation for aggression-focused treatment and technological limitations. The present findings suggest further studies are needed on how to best implement VR-assisted treatments for aggression in forensic settings, and potentially further modification of treatment content in interventions like VRAPT.

Characteristics of forensic psychiatric patients with a neurocognitive disorder.

Emotional and behavioural disturbances accompanying neurocognitive disorders may sometimes lead to a criminal offence. Our knowledge of this specific forensic subpopulation is lagging behind the knowledge on, and attention for, 'classic' psychiatric disorders in forensic populations. To gain knowledge on the prevalence and characteristics of individuals with neurocognitive disorders in the forensic population. This retrospective database study uses an anonymised data-set of the National Database of penitentiary psychiatric centres (PPC) (N = 8391), which collects data on all patients admitted to one of the four PPCs (mental health clinics within the prison system) in The Netherlands since May 2013. Inclusion criterion for this study was the presence of a Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision (DSM-IV-TR) or Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) diagnostic code belonging to the category of neurocognitive disorders. A DSM-IV-TR or DSM-5 diagnostic code of a neurocognitive disorder was classified in 254 out of 8391 unique individuals, resulting in a prevalence of 3.0% in the total PPC population. The most prevalent diagnosis was unspecified neurocognitive disorder (59.1%). The neurocognitive disorder group significantly differed from a random control group from the database (n = 762) on demographic, clinical and criminological variables. The prevalence of neurocognitive disorders in this real-world clinical sample is remarkably lower than in two earlier studies in similar populations. Also remarkable is the relatively high prevalence of an unspecified neurocognitive disorder. These findings lead us to hypothesise that neurocognitive disorders may be underdiagnosed in this population. Forensic psychiatric settings should evaluate whether they have sufficient expertise available in neuropsychological assessment.

Examining the Mr Tsafendas enquiry trial: Current insights on forensic psychiatric assessment and ethics

On 6 September 1966, the prime minister of South Africa, Dr HF Verwoerd was killed by Mr Tsafendas, a Portuguese national of Greek descent, in parliament by stabbing him in the chest. Mr Tsafendas was a messenger in parliament. At the enquiry trial of Mr Tsafendas, he was found unfit to stand trial on the ground that he suffered from schizophrenia. The psychiatric evidence during the enquiry trial was reviewed and discussed under the following headings: Diagnosis of schizophrenia; Consideration of cultural factors in forensic psychiatric settings; Delusional infestation v. extreme overvalued beliefs; Simulation of psychosis; Ethical considerations in criminal capacity and trial competency assessments. Lessons from the Mr Tsafendas enquiry trial for forensic psychiatrists where a defendant previously diagnosed with schizophrenia commits a prominent political murder, are summarised. It is emphasised that the personhood of an accused referred for forensic observation should be respected and protected, instead of focusing exclusively on a specific diagnosis.

Co-design of a digital violence prevention and management tool for psychiatric inpatient care: focus on supporting integration into electronic health record system

IntroductionViolence in psychiatric inpatient settings is a global challenge. Several methods have been developed and tested to help staff prevent the occurrence of violence on the wards. One novel and effective method is eDASA+APP, originating from Australian forensic psychiatric settings (Maguire et al. Int J Ment Health Nurs 2019; 281186-1197, Griffith et al. Psychiatr Serv 2021; 72 885-890). This electronic method contains an instrument (DASA) to assess the risk for imminent violence and includes evidence-based violence risk management methods for risk levels. It is important to ensure that this electronic intervention is integrated into daily clinical practice. This can be done in co-design between all that are involved e.g., staff and experts by experience, and by encouraging them to achieve a common goal and gain benefits by working together.ObjectivesThis prevention gives an overview of how the Finnish version of eDASA+APP was co-designed with healthcare staff and experts by experience, focusing on integration into the electronic patient health record system. The presentation is part of a larger research project testing eDASA+APP in Finnish psychiatric inpatient care.MethodsCo-design workshops focusing on three major themes: 1) identifying current practices and how eDASA+APP would fit in those, 2) producing a linguistically and culturally appropriate version of eDASA+APP, and 3) preferred use of eDASA+APP in an electronic patient health record system. Notes were kept during the workshops by researchers. Qualitative material were analysed with deductive content analysis. Results from the third theme are shared in this presentation.ResultsStaff and experts by experience described that integration of eDASA+APP in electronic patient health record system is supported if it 1) brings clear and fast information to the staff about the violence risk of a patient, 2) is a visible measure that is concretely in sight in electronic patient health record system, 3) provides information about which violence prevention and management interventions have worked with a patient, 4) involves patient preferences, and 5) consist of joint decisions that have been agreed multi-professionally.ConclusionsIntegration of eDASA+APP in the electronic patient health record system has the potential to succeed if it is realized in cooperation with staff and experts by experience, is technically easy to use, and the users have an understanding of its benefits to everyone involved.Disclosure of InterestNone Declared

What effects does peer support work have and how to implement it into forensic hospitals? A Review of Reviews

IntroductionDespite promising research there is still hesitation in implementing peer support work in some hospitals. Especially in forensic hospitals reservations are held against peer support workers.ObjectivesWe aim to give an overview of reviews about the effects of peer support work in psychiatric settings and its implementation. Special emphasis on implications for forensic psychiatric settings shall be given.MethodsFive electronic databases and archives of four relevant journals were searched in December 2019 and updated in April 2022. In addition, references of articles were searched and relevant authors were contacted for unpublished data. Results of reviews were clustered by one author and checked by another.Results22 reviews were identified of which 15 reported on effects of peer support work and six on factors influencing its implementation and one review on both. Several effects of peer support work on clinical, psychosocial, organizational and other outcomes (e.g., cost savings) were described. Psychosocial outcomes were the most promising ones whereas no effects were described in most reviews for clinical, organizational and other outcomes. Factors influencing the implementation of peer support work were described during preparation, recruitment, early employment and further development of the peer support worker’s roles. Most factors, beneficial and challenging, were described for the preparation stage of the implementation process.ConclusionsThe authors of the reviews often reported concerns about the low quality of the included studies. Therefore, the present results have to be considered as preliminary. Nevertheless, it is clear that peer support has a positive influence on psychosocial factors and thus complements classic therapeutic approaches. To achieve the best possible effect, the implementation of peer support needs to be carefully planned. Further studies are necessary in order to be able to consider the effect of recovery support in a more differentiated way.Disclosure of InterestNone Declared

The gendered context of women charged with violent offences in the forensic psychiatric setting.

Women charged with violent offences may be referred by courts for forensic psychiatric assessment to determine whether mental disorder or intellectual disability impacts their fitness to stand trial and/or criminal responsibility. The profile of these women is a poorly researched area in South Africa. This study examined the socio-demographic, offence-related, and clinical profile of South African women charged with violent offences referred for forensic assessment. Fort England Hospital (FEH), a forensic psychiatric institution in the Eastern Cape. The clinical records of 173 women referred by courts for forensic psychiatric evaluation over a 24-year period (1993-2017) to FEH were systematically reviewed. Most women were single, black mothers with dependent children, who were unemployed and socio-economically impoverished. Many had backgrounds of pre-offence mental illness, alcohol use and alleged abuse. The majority were first-time offenders whose victims were known to them. Most child victims were biological children killed by their mothers. Likely primary motives for violence were related to psychopathology in half of cases, and interpersonal conflict in a third. Forensic assessment most frequently confirmed psychotic disorders and dual diagnoses. Half the cases were fit to stand trial and under half were criminally responsible. Violent female offending occurs within a gendered context, with high rates of prior trauma, alcohol use and psychosocial distress in perpetrators. An emphasis on gender-sensitive psychosocial interventions is required. This study highlights the nature and context of violent offending by women referred for forensic psychiatric assessment in South Africa.

Factors influencing the length of stay in forensic psychiatric settings: a systematic review

BackgroundForensic psychiatry is often associated with long admissions and has a high cost of care. There is little known about factors influencing length of stay (LOS), and no previous systematic review has synthesised the available data. This paper aims to identify factors influencing the LOS in forensic psychiatry hospitals to inform care and interventions that may reduce the length of admissions.MethodologyA systematic review was conducted by searching major databases, including PubMed, EMBASE and PsycInfo, from inception until May 2022. Observational studies conducted in forensic hospitals that examined associations between variables of interest and LOS were included. Following data extraction, the Newcastle‒Ottawa Scale was used for quality appraisal. No meta-analysis was conducted due to heterogeneity of information; a quantitative measure to assess the strength of evidence was developed and reported.ResultsA total of 28 studies met the inclusion criteria out of 1606 citations. A detailed quantitative synthesis was performed using robust criteria. Having committed homicide/attempted homicide, a criminal legal status with restrictions, and a diagnosis of schizophrenia-spectrum disorders were all associated with longer LOS. Higher Global Assessment of Functioning (GAF) scores were associated with a shorter LOS.ConclusionHigh-quality research examining factors associated with LOS in forensic psychiatry is lacking, and studies are heterogeneous. No modifiable characteristics were identified, and thus, practice recommendations were not made. There is an increasing necessity to understand the factors associated with longer admissions to inform care and increase success in reintegration and rehabilitation. This paper provides recommendations for future research.

An Update Review to Cast Light on the Possible Role of Altered Oropharyngeal Microbiota in Differentiating True Psychosis from Malingered Psychosis in a Forensic Psychiatric Setting

Over the past few years, malingered psychosis has had a progressive occurrence since a great deal of attention has been directed to the closures of long-stay psychiatric institutions and care in the community. Therefore, malingered psychosis needs to be identified to conduct precise forensic assessments and prevent miscarriages of justice and misuse of restricted healthcare resources. Although, over the past decades, researchers have introduced a number of workable psychometric strategies and tools for diagnosing true psychosis, it is still sometimes challenging to differentiate between true and malingered psychosis. Hence, identifying reliable and innovative diagnostic alternatives seems crucial. Accordingly, a summary of gathered evidence is provided by the present review for enhancing future evaluation of oropharyngeal microbiome composition as a practical indicator for diagnosing true psychosis in a forensic psychiatric setting. As per the systematic search terms (namely, “diagnostic marker,” “oropharyngeal microbiome,” “forensic psychiatric setting,” “psychosis,” and “oropharyngeal microbiota”), relevant English publications were searched from January 1, 1980, to September 15, 2023, in Scopus, the Web of Science, Embase, Cochrane Library, PubMed, and Google Scholar databases. Finally, eight articles were included in the present review. Also, we adopted the narrative technique so that the material synthesis leads to a cohesive and compelling story. The results revealed that the periodontal disease and saliva microbiome were possibly associated with true psychosis. Thus, since oropharyngeal microbial compositions are highly different among healthy controls and patients with true psychosis, future research can take advantage of saliva to differentiate between fake and true fake psychosis throughout the initial stages of forensic psychiatric assessment. As a substrate of interest, saliva could also be used for characterizing the various stages of psychosis under a forensic psychiatric setting.

The possible role of altered oropharyngeal microbiota in differentiating true psychosis from malingered psychosis in a forensic psychiatric setting

Over the past few years, malingered psychosis has had a progressive occurrence since a great deal of attention has been directed to the closures of long-stay psychiatric institutions and care in the community. Therefore, malingered psychosis needs to be identified to conduct precise forensic assessments and prevent miscarriages of justice and misuse of restricted healthcare resources. Although, over the past decades, some practical psychometric and strategic tools have been introduced to diagnose true psychosis, it is still sometimes challenging to differentiate between true and malingered psychosis. Hence, identifying reliable and innovative diagnostic alternatives seems crucial. In this respect, some preliminary results revealed the saliva microbiome and periodontal disease were potentially associated with true psychosis. Therefore, since oropharyngeal microbial compositions are highly different among healthy controls and patients with true psychosis, we hypothesized that future research can take advantage of oropharyngeal microbiota composition to differentiate between true and fake psychosis during the early stages of forensic psychiatric evaluation. As a substrate of interest, oropharyngeal secretion samples could also be used for characterizing the various stages of psychosis in a forensic psychiatric setting.

Institutional influence on length of stay in German forensic hospitals: a multilevel analysis of patients with schizophrenia spectrum disorders.

Scientific studies have focused on patient-related characteristics as predictors of length of stay in forensic psychiatry. However, little attention has been paid to the specificities of forensic psychiatric settings. This study aims to test whether differences in forensic admissions transcend individual factors by comparing length of stay between different psychiatric units, controlling for hospital characteristics and patient characteristics. The dataset was derived from a forensic documentation system containing a wide range of information on forensic psychiatric patients. N = 594 patients with schizophrenia spectrum disorders discharged from 6 forensic hospitals in southern Germany were included in a linear mixed regression model. Linear mixed models were calculated, allowing for the simultaneous estimation of variance between patients and hospitals. The final regression model explained 49% of the total variance. The only statistically significant patient-related predictors were age at admission, education and severity of the index offence. Hospital differences explained 41% (ICC) of the variance in length of stay without finding a significant hospital effect in the data. Previous research has primarily analyzed predictors of length of stay in terms of individual patient characteristics. This work suggests that variables other than patient-related factors need to be considered when assessing the length of stay in forensic units. Further multi-center studies are needed to gain a better understanding of how forensic psychiatric hospitals and other institutional influences affect length of stay.

Self-harming behaviors and forensic system-related factors: an analysis of the Ontario review board database

BackgroundIn Canada, ensuring public safety, and the safety and well-being of accused individuals under the jurisdiction of the provincial review board are very important. While previous studies have reported a significant risk of self-harming behaviors (non-suicidal self-injury and suicide attempt) in forensic psychiatric settings, no large population study has assessed any relationship between forensic system-related factors and self-harming behaviors. A better understanding of these factors can help clinicians implement protective measures to mitigate self-harming behaviors or actions.MethodsUsing the Ontario Review Board (ORB) database covering 2014–2015 period (n = 1211, mean age = 42.5 ± 13.37 years, males = 86.1%), we analyzed the prevalence and factors associated with self-harming behaviors, emphasizing the characterization of the forensic system-related factors (ORB status, legal status, type of offense, previous criminal history, and victim relationship). The relationships between the forensic system-related factors and self-harming behaviors were explored using five separate logistic regression models, controlling for clinical and sociodemographic characteristics.ResultsApproximately 4% of the individuals in the forensic system over the study period engaged in self-harming behaviors Among the studied patients, individuals determined to be unfit to stand trial and inpatients were significantly more likely to have self-harming behaviors. There was no significant relationship between the type of offence, victim relationship, and previous criminal history with self-harming behavior.ConclusionForensic psychiatry inpatients should have close observation, screening, monitoring, and individual tailored management strategies for self-harming behaviors. The findings of this study indicate that forensic system-related factors, especially those that pertain to the status of individuals in the forensic system (i.e., unfit to stand trial and being an inpatient) are more responsible for self-harming behaviors among forensic patients in Ontario.

Family orientation in forensic psychiatric care: An uncertain foundation of distrust

The patients in forensic psychiatric care (FPC) are affected by their illness and the care they receive, but their families are also affected. The family-systems nursing theory has the mutual influence of the family as constituting a core starting point for the health of both the individual and the family and focuses on helping families cope with their situation. The aim of the study was to describe healthcare professionals' experiences of their family-oriented work within FPC. The findings are presented in three themes: A longed-for reciprocity within and with the family, Maintaining a problem-oriented and individual-based tradition, and Caring built on a foundation of distrust. Family-oriented work among healthcare professionals in FPC can only be realized through a pervasive shift in perspective from a predominantly problem-oriented patient focus towards a focus on interactional interplay and patterns. This is based on the belief that there are potential resources for patients and families to change in a healthy way. An educational intervention is suggested as a core starting point for developing a family-oriented practice for healthcare professionals in forensic psychiatric settings.

Oropharyngeal microbiome composition as a possible diagnostic marker for true psychosis in a forensic psychiatric setting: A narrative literature review and an opinion

The malingered psychosis has increasingly occurred over the past few years due to the tendency towards care in the community and the closures of long-stay psychiatric institutions. Thus, it is required to identify malingered psychosis to reach accurate forensic assessments and inhibit misuse of restricted healthcare resources and miscarriages of justice. Despite the fact that some practical psychometric tools and strategies have been proposed for diagnosing true psychosis over the past decades, the differentiation between true psychosis and malingered psychosis is still sometimes challenging. Accordingly, it seems crucial to identify innovative and reliable diagnostic alternatives. Hence, the present article summarizes a collection of evidence that can be used by researchers to improve future assessment of oropharyngeal microbiome composition as a feasible diagnostic marker for true psychosis in a forensic psychiatric setting.

Nutritional factors associated with aggression.

Although the vast majority of patients in forensic psychiatry are treated using pharmacological agents, clinical and ethical concerns about their use have led to the consideration of alternative strategies to reduce aggression that is common in forensic psychiatric settings. One non-invasive and benign biologically-based treatment approach involves nutrition. This article provides a mini-review of the recent evidence on four salient nutritional factors associated with aggressive behavior, namely omega-3 fatty acids, vitamin D, magnesium, and zinc. The current evidence base indicates that lower omega-3 levels are associated with increased aggression. Although research on vitamin D and zinc in relation to aggressive behavior is more limited, there is initial evidence that they are negatively associated with aggression in healthy participants and in psychiatric samples. The relationship between magnesium and aggression varies depending on how magnesium is assessed. Findings from experimental trials reveal that nutritional intervention in the form of omega-3 supplementation has the potential to serve as an effective mode of treatment, with effects that can last beyond the intervention period. There is also support for the utility of nutrition to improve our understanding of how social processes are linked to aggression. In light of the nascent, but promising findings on the role of nutritional factors on aggressive behavior, directions for future research are discussed.

Is mental health staff training in de-escalation techniques effective in reducing violent incidents in forensic psychiatric settings? – A systematic review of the literature

BackgroundInpatient violence is a relevant issue in forensic psychiatric settings. Relevant guidelines recommend that restrictive measures are to be used exclusively if de-escalation and other preventive strategies have failed and there is a risk of harm to patients or staff if no action is taken. However, restrictive measures are untherapeutic and can be harmful. In order to enable staff to intervene before inpatient violence or other serious incidents occur and thus to avoid restrictive measures, mental health staff training programs including de-escalation components are being adopted in general as well as forensic mental health settings. There is growing evidence for the efficacy of mental health staff training in de-escalation techniques in the field of general psychiatry. However, there are no reviews evaluating the effectiveness of these interventions in reducing violent incidents in forensic psychiatric settings. Here we present the first literature review on the effectiveness staff training in de-escalation techniques in the field of forensic psychiatry.MethodWe searched relevant databases for original research on the effectiveness of reducing violence in forensic psychiatric settings. Studies were included if they investigated staff training programs with de-escalation techniques in forensic mental health settings.ResultsA total of 5 relevant studies were identified. None of the studies was a randomized controlled trial. Four studies were before and after comparisons without control group. A one group post-test-only design was used in one study. Methodological quality was low. The maximum sample size was 112 participants. Results indicated no relevant impact of mental health staff training in de-escalation techniques on the rate of violent incidents in forensic psychiatric wards. However, staff seemed to feel safer following the training. Results have to be interpreted cautiously due to several methodological and content-related limitations.DiscussionEvidence for the effectiveness of staff training in de-escalation techniques on reducing verbal and physical aggression in forensic settings remains very limited. The existing definitions of terms like de-escalation, de-escalation training and de-escalation techniques in the healthcare context appear rather vague. Although some positive changes are reported across a variety of outcome measures it remains unclear to what extent staff training in de-esclation techniques contributes to a reduction in aggressive incidents and restrictive measures in forensic psychiatry. The clinical implications of this review are therefore limited. Yet, an important implication for future research is that a more comprehensive approach might prove worthwhile. Conducting a further review integrating a wide range of complex interventions aimed at the reduction of inpatient violence rather than focusing on de-escalation only, might be a worthwhile approach.

Exploring the psychometric properties of the externalizing spectrum inventory-brief form in a Swedish forensic psychiatric inpatient sample

BackgroundThe Externalizing Spectrum Inventory-Brief Form (ESI-BF) [1] is a 160-item self-report instrument designed for the assessment of externalizing psychopathology, yet few studies to date have evaluated its psychometric properties, structural fit, and criterion validity in forensic psychiatric settings.MethodsHere, we investigated these aspects in a sample of forensic psychiatric inpatients (n = 77) from a maximum-security forensic psychiatric hospital in Sweden. We firstly investigated the reliability. Secondly, using confirmatory factor analysis, the structure of the ESI-BF. And thirdly, using a Bayesian approach, assessed how the three ESI-BF subfactors relate to criterion measures of antisocial behaviors, substance use, and lifetime externalizing spectrum diagnoses.ResultsThe ESI-BF demonstrated good to adequate reliability and internal consistency, with all but four facet scales exhibiting α and ω values ≥ 0.80. Average inter-item correlations for the facet scales ranged from 0.31 to 0.74. However, all structural models exhibited poor to mediocre fit, with model fit values for the CFI being 0.66, 0.79 and 0.87 and RMSEA values of 0.14, 0.12 and 0.09. for the unidimensional correlated factors and bifactor model, respectively. Regarding criterion validity, all subscales of the item-based ESI-BF three-factor model exhibited robust correlations with the Life History of Aggression total, aggression and antisocial/consequences subscales, with correlations ranging from 0.29 to 0.55. All ESI-BF subfactors demonstrated robust associations, yet with different externalizing outcomes, lending tentative support to its criterion validity.ConclusionDespite remaining ambiguities regarding its structural fit, the ESI-BF may be promising for assessing externalizing psychopathology in forensic psychiatric populations. However, further investigation of the ESI-BF is needed before any firm conclusions can be drawn about its appropriateness in forensic psychiatric settings.

Psychometric properties of the Parma Scale for the treatment evaluation of prisoners with mental disorder: a new instrument for routine outcome monitoring in different forensic psychiatric settings

IntroductionThe clinical relevance of Routine Outcome Monitoring (ROM) to formulate longitudinal evaluations of treatment appropriateness/efficacy and to assist decision making aimed at improving the quality of person-centered interventions has been poorly implemented in forensic psychiatry, also in Italy. Indeed, very few assessment instruments have been developed in this crucial field.ObjectivesAs reliable ROM instruments are lacking, the aim of the current investigation was to examine psychometric properties (i.e. reliability, concurrent validity and sensitivity to measure scores’ longitudinal changes) of the Parma Scale (Pr-Scale) (a new instrument fro the evaluation of offenders with mental disorder) in an Italian sample of forensic psychiatric patients.MethodsParticipants were male adult offenders with mental disorder recruited within the Parma REMS (“Residence for the Execution of Security Measure”) or the Parma Penitentiary Institute (PPI). Exclusion criteria were known moderate/severe intellectual disability or any other medical condition inducing inability to express a valid consent for participating in the research. The Pr-Scale includes 20 items divided into 3 main domains: “Historical”, “Clinical” (observational) and “Treatment Plannining". To test psychometric properties of the Pr-Scale, we examined interrater reliability, short-term (1-week) test-retest reliability and internal consistency. As measure of concurrent validity, a correlation analysis of Pr-Scale item scores with corresponding HKT-R (the “Historisch, Klinische en Toekomstige – Revisie” instrument) item subscores was performed. Finally, we examined the Pr-Scale sensitivity to measure scores’ longitudinal changes over a 3-month treatment follow-up period.Results60 male adult patients were recruited in this study. Our findings showed good to excellent interrater and test-retest reliability, concurrent validity and internal consistency for the Pr-Scale. Pr-Scale scores also display a moderate to large changeability over time (Intra-Class Correlation coefficient = 0.963, coefficient of stability = 0.997, Cronbach’s ɑ = 0.736). Statistically significant correlations of Pr-Scale item scores with the corresponding HKT-R scores were found. Across the 3-month follow-up period, we observed statistically significant sensitivity values in measuring longitudinal changes for the Pr-Scale total score and Pr-Scale domain and item subscores.ConclusionsOur results support the clinical use of the Pr-Scale in different forensic psychiatric settings (i.e. prison, REMS) as reliable ROM instrument.Disclosure of InterestNone Declared

The HARM models: Predicting longitudinal physical aggression in patients with schizophrenia at an individual level

The prediction and prevention of aggression in individuals with schizophrenia remains a top priority within forensic psychiatric settings. While risk assessment methods are well rooted in forensic psychiatry, there are no available tools to predict longitudinal physical aggression in patients with schizophrenia within forensic settings at an individual level. In the present study, we used evidence-based risk and protective factors, as well as variables related to course of treatment assessed at baseline, to predict prospective incidents of physical aggression (4-month, 12-month, and 18-month follow-up) among 151 patients with schizophrenia within the forensic mental healthcare system. Across our HARM models, the balanced accuracy (sensitivity + specificity/2) of predicting physical aggressive incidents in patients with schizophrenia ranged from 59.73 to 87.33% at 4-month follow-up, 68.31–80.10% at 12-month follow-up, and 46.22–81.63% at 18-month follow-up, respectively. Additionally, we developed separate models, using clinician rated clinical judgement of short term and immediate violent risk, as a measure of comparison. Several modifiable evidence-based predictors of prospective physical aggression in schizophrenia were identified, including impulse control, substance abuse, impulsivity, treatment non-adherence, mood and psychotic symptoms, substance abuse, and poor family support. To the best of our knowledge, our HARM models are the first to predict longitudinal physical aggression at an individual level in patients with schizophrenia in forensic settings. However, it is important to caution that since these machine learning models were developed in the context of forensic settings, they may not be generalisable to individuals with schizophrenia more broadly. Moreover, a low base rate of physical aggression was observed in the testing set (6.0–11.6% across timepoints). As such, larger cohorts will be required to determine the replicability of these findings.
