Research Progress and Application Prospect of Facial Micro-Expression Analysis in Forensic Psychiatry

Research on facial micro-expression analysis has been going on for decades. Micro-expression can reflect the true emotions of individuals, and it has important application value in assisting auxiliary diagnosis and disease monitoring of mental disorders. In recent years, the development of artificial intelligence and big data technology has made the automatic recognition of micro-expressions possible, which will make micro-expression analysis more convenient and more widely used. This paper reviews the development of facial micro-expression analysis and its application in forensic psychiatry, to look into further application prospects and development direction.

Risk, resilience, and recovery in forensic mental health: An integrated conceptual model

In this paper we describe a novel, integrated conceptual model that brings together core elements across structured tools assessing risk for future violence, protective factors, and progress in treatment and recovery in forensic mental health settings. We argue that the value of such a model lies in its ability to improve clinical efficiencies and streamline assessment protocols, facilitate meaningful participation of patients in assessment and treatment planning activities and increase the accessibility of clinical assessments to principal users of this information. The four domains appearing in the model (treatment engagement, stability of illness and behavior, insight, and professional and personal support) are described, and common clinical manifestations of each domain within a forensic context are illustrated. We conclude with a discussion of the types of research that would be needed to validate a concept model such as the one presented here as well as implications for clinical practice and implementation.

Risk of violent behaviour in young people at clinical high risk for psychosis from the North American Prodrome Longitudinal Studies consortium

AIM

Although violent behaviour has been studied in schizophrenia, violence risk has received little attention in individuals at clinical high risk for psychosis (CHR). This manuscript aims to report and discuss the overall results of the Structured Assessment for Violence Risk in Youth (SAVRY) from the NAPLS-3 project to explore the risk of violence in CHR youth and to determine the relationship between SAVRY violence risk scores, psychosis risk symptoms, and global functioning. We hypothesized that CHR young people are at higher risk of violence as compared to healthy comparison participants due to a similarity between risk factors for psychosis and risk factors for violence, and that this risk is associated with greater severity of symptoms, poor functioning, and risk for conversion to psychosis.

METHODS

Participants from the North American Prodrome Longitudinal Study consortium phase 3 (NAPLS-3) included 684 CHR and 96 HC. Assessments included the Structural Assessment of Violence Risk in Youth (SAVRY), clinical and functional measures.

RESULTS

The majority of participants across groups were deemed to be at low risk for violence. There were significantly more CHR participants (29.8%) who had moderate or high scores on the SAVRY Summary Risk Rating compared to HC participants (3.1%). Low versus moderate-high SAVRY scores were associated with better social (p < .005) and role (p < .002) functioning and fewer positive (p < .002), negative (p < .002), disorganized (p < .01) and general symptoms (p < .002). CHR participants with higher SAVRY scores were more likely to be diagnosed with borderline personality disorder, ADHD and substance misuse. Among CHR, overall violence risk was not associated with conversion to psychosis. However, those who converted to psychosis scored lower on the protective factors index, primarily driven by less prosocial involvement and fewer resilient personality traits.

CONCLUSIONS

This is the first study to assess violence risk in CHR adolescents. Violence risk factors overlap with risk factors for psychosis in general, perhaps accounting for the association. These findings have implications for intervention efforts to reduce violence risk and bolster resiliency in CHR youth.

Effects of Psychiatric Disease Severity and Clinical Characteristics on Duration of High Violence Risk: A Perspective on Violence Prevention in the Psychiatric Ward

Objective

Prevention, de-escalation, and management of violence in the acute psychiatric ward is essential. Few studies have focused on differences in the duration of high-violence risk between different profiles of high-violence risk. This study aimed to analyze the data of high-violence patients and duration of high-violence risk to provide a new perspective on violence prevention, de-escalation and management.

Methods

This retrospective observational cohort study included 171 patients who were treated in the acute psychiatric ward of Keelung Chang Gung Memorial Hospital between January 2016 and June 2020, and who were assessed daily as having high violence risk. All patient data were collected from electronic hospital records (eg, age, gender, diagnosis, violence history, self-harm history, and admission condition (involuntary admission, discharged against medical advice). Between-group differences in disease severity, use of antipsychotics and benzodiazepine, and duration of high violence risk were analyzed using regression analysis.

Results

Only patients' age was significantly associated with duration of high-violence risk (P = 0.028), making it predictive of longer duration of high-violence risk. In patients with schizophrenia spectrum disorder or bipolar disorder, higher severity was significantly associated with longer duration of high-violence risk (P = 0.007, P = 0.001, respectively).

Conclusion

Only age is a predictor of longer duration of violence risk in psychiatric patients, although higher severity is associated with higher violence risk. Study results may help management and healthcare staff better understand how quickly or slowly violence risk will decrease and may improve efficient use of healthcare resources and individualized patient-centered care.

Violence in relation to cognitive deficits and symptom severity in a sample of Egyptian patients with schizophrenia

BACKGROUND

Patient with schizophrenia are significantly more likely to be violent than general population; and the consequences of this violence risk are often very serious for the patients, their caregivers, and the entire community.

AIM

To assess the risk of violence in patients with schizophrenia and its correlation with severity of symptoms and cognitive functions.

METHODS

A cross-sectional comparative study conducted in Okasha institute of psychiatry including 50 patients with schizophrenia compared to 50 healthy control group regarding violence risk as assessed by Historical, Clinical, and Risk Management-20 (HCR-20), case group was assessed using Structured Clinical Interview for DSM-IV (SCID-I), Positive and Negative Syndrome Scale (PANSS), cognitive functions were assessed by Wechsler Adult Intelligence Scale (WAIS), Trail Making Test (TMT) Part A and B, the Wisconsin Card Sorting Test (WCST), and the Wechsler Memory Scale (WMS).

RESULTS

There was a statistically significant difference between case and control groups regarding risk of violence where 58% of the case group were found to have risk of violence compared to only 18% in the control group. There was a significant correlation between this risk of violence and period of untreated psychosis, no of episodes, and history of substance use; also was significantly correlated with PANSS and Wisconsin card sorting test subscales. Regarding logistic regression analysis for factors affecting violence risk; total PANSS score and history of substance use were significant independent factors that increase violence risk.

CONCLUSION

Violence risk in patient with schizophrenia is a cardinal factor that may affect life of the patients, their family, and society; this risk can be affected by different factors including severity of symptoms, no of episodes, history of substance use, and cognitive function of the patients.

The Ontario Forensic Mental Health System: A Population-based Review

OBJECTIVE

The purpose of this study was to increase the understanding of the Canadian forensic psychiatry system by providing a population-based overview of the Ontario forensic mental health system.

METHODS

Data were collected on 1,240 accused adults who were subject to the jurisdiction of the Ontario Review Board (ORB) between 2014 and 2015. Archival data were retrieved from annual ORB hearing hospital reports for accused supervised by all nine adult forensic psychiatry facilities across Ontario.

RESULTS

The sample included not criminally responsible (NCR; 91.6%) and unfit to stand trial (UST; 8.4%) accused. The majority of the sample was male (85.7%), single (70.1%), unemployed (63.6%), with a high school education (48.8%). Most were on a detention order (78.5%) and almost half were living in the community at the time of the report (48.8%). The majority had prior contact with psychiatric services (83.1%) and/or the criminal justice system (70.6%) before entering the forensic system. A history of elopement (31.5%) and inpatient aggression was high (60.6%). Most had a psychotic spectrum disorder (81.6%) and over half had a substance use disorder (57.2%) in the reporting year. A range of index offences was observed (69.9% violent, 20.3% general, 9.8% sexual), and the majority of the sample (61.0%) had an index offence that resulted in no injury or a minor injury to the victim.

CONCLUSION

The Canadian forensic psychiatry system is comprised of a unique subset of justice-involved individuals. This study provides a detailed examination of accused who are subject to the jurisdiction of the ORB and provides key insight into risk factors associated with offending behaviour in this population. The results of this study will provide a framework for future studies examining the association between mental disorder and violence and the treatment trajectories for those in the forensic psychiatry system.

The influence of changes in clinical factors on high-security forensic custody dispositions

The demand for forensic psychiatric beds is increasing, while many individuals are "stuck" in the system. Index offense severity and other legal considerations are associated with longer forensic stays but factors amenable to change such as symptoms of mental illness and aggression may also influence forensic decisions. We examined forensic review board decisions over time among 89 men admitted to a high-security forensic hospital. Almost half received a disposition to remain at their first hearing. Overall, dispositions were not associated with violence risk. The odds of a disposition to remain were higher for men with more in-hospital assaults and higher scores on a measure of clinical factors. Dispositions changed over time and this change was sensitive to clinical factors. We conclude that decisions were consistent with a cascading system of loosening security over time. Further longitudinal research following large samples through the forensic system is recommended.

Outcome measures of risk and recovery in Broadmoor High Secure Forensic Hospital: stratification of care pathways and moves to medium secure hospitals

BACKGROUND

Placements within high secure forensic hospitals consist of wards providing various different levels of relational security. They should form a coherent pathway through secure care, based on individual patient risks and needs. Moves to less secure wards within high secure forensic hospitals and moves on to lower secure hospital settings have rarely been systematically studied.

AIMS

The aim of this study was to ascertain if placements within Broadmoor High Secure Hospital and moves from Broadmoor to medium secure hospitals corresponded to measures of violence risk, programme completion and recovery.

METHOD

A 13-month prospective cohort study was completed. Patients (n = 142) were rated at baseline for violence risk (Historical, Clinical and Risk - 20), therapeutic programme completion and recovery (DUNDRUM tool) and overall functioning (Global Assessment of Functioning). Placements on the care pathway and moves on to medium secure hospitals were observed.

RESULTS

Placements on the care pathway within the high secure hospital were associated with dynamic violence risk (F = 16.324, P<0.001), therapeutic programme completion (F = 4.167, P = 0.003), recovery (F = 2.440, P = 0.050) with better scores on these measures being found in the rehabilitation wards and the poorest scores on the highest levels of dependency. Moves to medium secure hospitals were associated with better scores on dynamic risk of violence (F = 33.199, P<0.001), therapeutic programme completion (F = 9.237 P<0.001), recovery (F = 6.863, P = 0.001).

CONCLUSIONS

Placements within Broadmoor Hospital formed a coherent pathway through high secure care. Moves to less secure places were influenced by more than reduction in violence risk. Therapeutic programme completion and recovery in a broad sense were also important.

The Perspective of Forensic Inpatients With Psychotic Disorders on Protective Factors Against Risk of Violent Behavior

Background: Little is known about the opinions of forensic inpatients with psychotic disorders like schizophrenia on factors likely to prevent or decrease future violent behavior. Aims: To understand the perspectives of forensic inpatients with psychotic disorders on protective factors against risk of violent behavior and compare them to factors identified by professional staff. Method: Using the Structured Assessment of Protective Factors (SAPROF) checklist for self-appraisal of violence risk, we conducted semi-structured interviews with 32 inpatients of the Medical Treatment and Supervision Act Ward and compared the results with those of professionals. Results: Inpatients scored higher in the SAPROF total score, the motivational factors of "life goals" and "motivation for treatment," and the protective level in general. Inpatients scored themselves lower in risk level than professionals. The degree of agreement between service users' and professionals' evaluations was low for all categories except external factors. Inpatients prioritized "life goals," "self-control," and "medication" as the top three key strengths currently preventing violent behavior, whereas the professionals selected "life goals" less often. The top three important future goals for preventing future violence selected by inpatients were "work," "intimate relationships," and "life goals," with the former two being selected significantly less often by the professionals. Conclusions: This is the first study to shed light on Japanese forensic inpatients' perspectives about preventing future violent behavior. Despite professionals' underestimation, inpatients viewed themselves as having high motivation for treatment and positive life goals. Inpatients prioritized personal values such as life goals, work, and intimate relationships, whereas professionals prioritized understanding, treating, and observing the disease. Our findings are consistent with past reports on patients' and clinicians' perspectives. Awareness of such gaps in perceptions can help build fruitful therapeutic alliances. We discuss the implications in terms of treatment, how to address the gap therapeutically, and how to design treatment accordingly. Directions for future research are also discussed.

Assessing the risk of violence in a psychiatric clinic: the Brøset Violence Checklist (BVC) Turkish version-validity and reliability study

PURPOSE

This study was conducted for the purpose of adapting the Brøset Violence Checklist (BVC) for Turkish patients and testing its validity and reliability in measuring and predicting the risk of violence psychiatric in patients.

DESIGN AND METHODS

The BVC and the Overt Aggression Scale (OAS) were used in the study. The BVC was distributed to 126 patients at the psychiatric clinic. The receiver operating characteristic (ROC), the Mann-Whitney U test and χ ² analysis were carried out.

FINDINGS

With a BVC total score cutoff of two points, 52% sensitivity and 100% specificity were found. A total of 47 violent episodes were observed in 25 patients.

PRACTICE IMPLICATIONS

These results support the validity and reliability of the BVC. The Turkish version of the BVC was found to be a reliable and valid tool suitable for use in psychiatric inpatients.

Effects of Psychoeducation and Stress Coping Techniques on Posttraumatic Stress Disorder Symptoms

This study examined the effects of psychoeducation and stress management techniques on Posttraumatic Stress Disorder (PTSD) symptoms in Libya. The 41 Libyan patients who volunteered to take part in the study were first assessed using the PTSD Checklist. They attended workshops on PTSD symptoms, stress management techniques, and communication skills on three successive days after which they were asked to answer the Coping Inventory for Stressful Situations two weeks after they completed the workshops. Among the 39% of the participants who were diagnosed with PTSD prior to the intervention, 15% met the diagnostic criteria for PTSD after the intervention. The preintervention scores were consistently higher than the postintervention scores, and there were significant differences in the PTSD Checklist total score and the re-experiencing, avoidance, and hyperarousal symptom scores. This study concluded that in mass-trauma events such as war and natural disasters, PTSD education can reduce the PTSD symptoms of those affected. Whether the benefits of psychoeducation on the participants are long term or short term is recommended for further study due to the limitations imposed by the willingness of the participants to participate, the amount of time they are willing to stay with the program, and the duration of the psychoeducation program itself.

Lone-actor Terrorism and Impulsivity

In some recent cases of lone-actor terrorism, there is evidence the subject acted impulsively, often in response to a triggering event which contained a loss and humiliation. Evidence suggests the subjects acted precipitously, despite planning and preparation carried out in the preceding weeks or months, and their attacks failed to include the often considerable preparation that had been done. The pathway became a runway. The authors recommend the traditional assessment of impulsivity in persons of concern for lone acts of terrorism, as well as other proximal warning behaviors for targeted violence. Both indirect and direct assessment guidelines are proposed, with an emphasis upon self-report, psychological testing, collateral data gathering, and historical records.

Assessing the reliability, predictive and construct validity of historical, clinical and risk management-20 (HCR-20) in Mexican psychiatric inpatients

INTRODUCTION

Assessing dangerousness to gauge the likelihood of future violent behaviour has become an integral part of clinical mental health practice in forensic and non-forensic psychiatric settings, one of the most effective instruments for this being the Historical, Clinical and Risk Management-20 (HCR-20).

OBJECTIVE

To examine the HCR-20 factor structure in Mexican psychiatric inpatients and to obtain its predictive validity and reliability for use in this population.

METHOD

In total, 225 patients diagnosed with psychotic, affective or personality disorders were included. The HCR-20 was applied at hospital admission and violent behaviours were assessed during psychiatric hospitalization using the Overt Aggression Scale (OAS). Construct validity, predictive validity and internal consistency were determined.

RESULTS

Violent behaviour remains more severe in patients classified in the high-risk group during hospitalization. Fifteen items displayed adequate communalities in the original designated domains of the HCR-20 and internal consistency of the instruments was high.

CONCLUSION

The HCR-20 is a suitable instrument for predicting violence risk in Mexican psychiatric inpatients.

Violence Risk Assessment and Management in Outpatient Clinical Practice

OBJECTIVE

The aims of this review were to highlight fundamental distinctions between risk assessment in forensic versus therapeutic settings, review the best available evidence regarding key risk and protective factors for violence of particular relevance to clinicians in outpatient therapeutic settings, and describe an approach to evaluating and managing violence risk in outpatient treatment.

METHOD

An integrative literature review was undertaken to examine violence risk and protective factors most relevant to outpatient clinicians in therapeutic settings.

RESULTS

Based on the available research, the Integrative Outpatient Violence Risk Assessment and Management (IVRAM) model, a 5-step strategy for evaluating and managing violence risk in therapeutic contexts, is introduced. The IVRAM emphasizes the integration of nomothetic and idiographic data through a focus on empirically derived dynamic risk and protective factors in the context of an individualized anamnestic analysis.

CONCLUSION

Clinicians working in forensic and therapeutic settings will increasingly benefit from the contributions of the other as the distinctions between risk assessment and risk management continue to decrease.

The drugs-violence nexus among Mexican-American gang members

This study examines hypotheses and builds models to help clarify the causal connections between drugs and violence outcomes among Mexican-American male gang members. The study uses cross-sectional data of 160 male gang members sampled from 26 gangs in a Southwestern city. A life-history /intensive interview using closed and open-ended questions and a violence risk psychometric test (PFAV) also employed 10 scenario questions to elicit self-produced accounts of the participant's last fight. Gang member participant's ages ranged from 14 to 25 years with a mean age of 18.5 years. The study concludes that drug use interacts with an individual gang member's risk for violence to affect violent behavior outcomes. Furthermore, an important situational variable explaining violent outcomes among respondents scoring high on the violence risk measure was whether the rival was using drugs that resulted in high intoxication levels. The study concludes that drugs have a modulating and mediating influence on violence that is conditioned by situational and individual level variables among members of these adolescent street gangs.
