The Structured Assessment of Violence Risk in Adults with Intellectual Disability: A Systematic Review

The predictive value of the dynamic risk outcome scales (DROS) for recidivism in (forensic) clients with mild intellectual disabilities or borderline intellectual functioning

BACKGROUND

The dynamic risk outcome scales (DROS) was developed to assess treatment progress of clients with mild intellectual disability or borderline intellectual functioning using dynamic risk factors. We studied the predictive value of the DROS on various classifications and severity levels of recidivism.

METHOD

Data of 250 forensic clients with intellectual disabilities were linked to recidivism data from the Judicial Information Service in the Netherlands. Receiver operating characteristics (ROC) analyses were used to determine the predictive values.

RESULTS

The DROS total score could not significantly predict recidivism. A DROS recidivism subscale predicted general, violent and other recidivism. These predictive values were comparable to those of a Dutch tool validated for risk assessment in the general forensic population.

CONCLUSIONS

The DROS recidivism subscale predicted various classifications of recidivism better than chance. At present, the DROS appears to have no added value beyond the HKT-30 for the purpose of risk assessment.

A Harmful Care: The Association of Informal Caregiver Burnout With Depression, Subjective Health, and Violence

Providing informal care to a relative can lead to informal caregiver burnout, which is expected to lead to deleterious consequences. Among these consequences lie the risk of perpetrating violent behaviors against the care-recipient, the caregivers' risk of depression, and their low subjective health. To investigate these associations, a sample of 499 informal caregivers completed a questionnaire addressing informal caregiver burnout, depression, subjective health, and violence. Hierarchical regression models were used to investigate the potential association of burnout with these potential consequences, while controlling for sociodemographic variables and received violence. The results show that burnout, and especially emotional exhaustion, is significantly associated with depression, low subjective health, and perpetrated physical violence, but not with perpetrated psychological violence. For both psychological and physical violence, it appears that receiving violence is one of the best predictors of perpetrating violence. With these results, this cross-sectional study confirms the association of informal caregiver burnout with deleterious consequences-even if this observation must be pondered-and the central role of received violence in predicting perpetrated violence, suggesting the risk of violence escalation. The implications of these results suggest that the emotional state of informal caregivers is one of the indicators of potential deleterious consequences and should, as such, be considered as a warning signal by field workers.

Exploring the victim offender overlap among people with an intellectual disability

BACKGROUND

While there is growing international evidence pointing to the increased risks of crime perpetration and victimisation for some people with an intellectual disability, the overlap between offending and victimisation (the victim-offender overlap) remains unclear.

METHOD

This study utilised a data linkage methodology of 2600 people with an intellectual disability, exploring their contacts with public mental health services and the police in Victoria, Australia.

RESULTS

Victim-offenders accounted for a small proportion of the sample (n = 148, 5.7%). The victim-offender overlap was evident for both violent and nonviolent nonsexual crimes, particularly for theft, burglary, and threat-related crimes. Key differences were also noted between males and females.

CONCLUSIONS

People with an intellectual disability who are both victim and offenders comprise a small but particularly complex justice-involved population. Future research should explore the victim offender overlap for males and females separately, as well as any additional risks and vulnerabilities associated with specific mental health diagnoses.

Usability and Acceptance of Wearable Biosensors in Forensic Psychiatry: Cross-sectional Questionnaire Study

Background

The use of wearable biosensor devices for monitoring and coaching in forensic psychiatric settings yields high expectations for improved self-regulation of emotions and behavior in clients and staff members. More so, if clients have mild intellectual disabilities (IQ 50-85), they might benefit from these biosensors as they are easy to use in everyday life, which ensures that clients can practice with the devices in multiple stress and arousal-inducing situations. However, research on (continuous) use and acceptance of biosensors in forensic psychiatry for clients with mild intellectual disabilities and their caretakers is scarce. Although wearable biosensors show promise for health care, recent research showed that the acceptance and continuous use of wearable devices in consumers is not as was anticipated, probably due to low expectations.

Objective

The main goal of this study was to investigate the associations between and determinants of the expectation of usability, the actual experienced usability, and the intention for continuous use of biosensors.

Methods

A total of 77 participants (31 forensic clients with mild intellectual disabilities and 46 forensic staff members) participated in a 1-week trial. Preceding the study, we selected 4 devices thought to benefit the participants in domains of self-regulation, physical health, or sleep. Qualitative and quantitative questionnaires were used that explored the determinants of usability, acceptance, and continuous use of biosensors. Questionnaires consisted of the System Usability Scale, the Technology Acceptance Model questionnaire, and the extended expectation confirmation model questionnaire.

Results

Only the experienced usability of the devices was associated with intended continuous use. Forensic clients scored higher on acceptance and intention for continuous use than staff members. Moderate associations were found between usability with acceptance and continuous use. Staff members showed stronger associations between usability and acceptance (r=.80, P<.001) and usability and continuous use (r=.79, P<.001) than clients, who showed more moderate correlations between usability and acceptance (r=.46, P=.01) and usability and continuous use (r=.52, P=.003). The qualitative questionnaires in general indicated that the devices were easy to use and gave clear information.

Conclusions

Contrary to expectations, it was the actual perceived usability of wearing a biosensor that was associated with continuous use and to a much lesser extent the expectancy of usability. Clients scored higher on acceptance and intention for continuous use, but associations between usability and both acceptance and continuous use were markedly stronger in staff members. This study provides clear directions on how to further investigate these associations. For example, whether this is a true effect or due to a social desirability bias in the client group must be investigated. Clients with mild intellectual disabilities might benefit from the ease of use of these devices and their continuing monitoring and coaching apps. For these clients, it is especially important to develop easy-to-use biosensors with a minimum requirement on cognitive capacity to increase usability, acceptance, and continuous use.

Identifying gaps in using artificial intelligence to support students with intellectual disabilities from education and health perspectives

Purpose

Students with developmental/intellectual disabilities (ID/DD) often have serious health issues that require additional medical care and supervision. Serious health issues also mean increased absence and additional lags in academic achievement and development of adaptive and social skills. The incorporation of artificial intelligence in the education of a child with ID/DD could ameliorate the educational, adaptive and social skill gaps that occur as a direct result of persistent health problems.

Design/methodology/approach

The literature regarding the use of artificial intelligence in education for students with ID/DD was collected systematically from international online databases based on specific inclusion and exclusion criteria. The collected articles were analyzed deductively, looking for the different gaps in the domain. Based on the literature, an artificial intelligence–based architecture is proposed and sketched.

Findings

The findings show that there are many gaps in supporting students with ID/DD through the utilization of artificial intelligence. Given that the majority of students with ID/DD often have serious and chronic and comorbid health conditions, the potential use of health information in artificial intelligence is even more critical. Therefore, there is a clear need to develop a system that facilitates communication and access to health information for students with ID/DD, one that provides information to caregivers and education providers, limits errors, and, therefore, improves these individuals' education and quality of life.

Practical implications

This review highlights the gap in the current literature regarding using artificial intelligence in supporting the education of students with ID/DD. There is an urgent need for an intelligent system in collaboration with the updated health information to improve the quality of services submitted for people with intellectual disabilities and as a result improving their quality of life.

Originality/value

This study contributes to the literature by highlighting the gaps in incorporating artificial intelligence and its service to individuals with ID/DD. The research additionally proposes a solution based on the confounding variables of students’ health and individual characteristics. This solution will provide an automated information flow as a functional diagnostic and intervention tool for teachers, caregivers and parents. It could potentially improve the educational and practical outcomes for individuals with ID/DD and, ultimately, their quality of life.

Predicting aggression in adults with intellectual disability: A pilot study of the predictive efficacy of the Current Risk of Violence and the Short Dynamic Risk Scale

BACKGROUND

Structured assessments have been shown to assist professionals to evaluate the risk of aggression in secure services for general offender populations and more recently among adults with intellectual disabilities. There is a need to develop intellectual disability sensitive measures for predicting risk of aggression in community samples, especially tools with a focus on dynamic variables.

METHODS

The study prospectively followed 28 participants for up to 2 months to test whether the Current Risk of Violence (CuRV) and Short Dynamic Risk Scale (SDRS) were able to predict verbal and physical aggression in a community sample of adults with intellectual disability.

RESULTS

CuRV and SDRS ratings significantly predicted verbal and physical aggression over a 2-month period.

CONCLUSIONS

The current study supports the use of the CuRV with adults with intellectual disability living in community settings. The CuRV and SDRS are worthy of future development and evaluation in independent investigations.

Psychometric properties of the Dynamic Risk Outcome Scales (DROS) for individuals with mild intellectual disability or borderline intellectual functioning and externalizing behaviour problems

BACKGROUND

The present study examined the psychometric properties of the Dynamic Risk Outcome Scales (DROS), an instrument developed to measure dynamic risk factors in individuals with mild intellectual disabilities or borderline intellectual functioning (MID-BIF) and externalizing (including offending-like) behaviour problems.

METHOD

The sample consisted of 606 clients (86% male) from inpatient treatment wards at a facility for individuals with MID-BIF and externalizing behaviour problems.

RESULTS

The DROS showed an acceptable factor structure, good internal consistency, significant test-retest reliability and fair to excellent inter-rater reliabilities for most subscales and total score. Compared to the Adult Behavior Checklist (ABCL; Achenbach & Rescorla, 2003 Manual for the ASEBA adult forms and profiles. Burlington, VT: University of Vermont, Research Center for Children, Youth, & Families), the DROS showed convergent and divergent validity, concurrent and longitudinal validity.

CONCLUSIONS

The DROS is a reliable and valid instrument to measure dynamic risk factors in clients with MID-BIF. Future research on the DROS will focus on the assessment of recidivism and the inclusion of internalizing problems.

[Barriers to and facilitators for using a risk assessment tool to prevent violent behaviour in patients with mental health conditions: Perspectives of health care providers]

Regular assessment of risk of violence is shown to be effective in reducing violence in mental health services.

PURPOSE

To evaluate health care providers' use of a violence risk assessment tool on a mental health unit and the facilitators for and barriers to its use.

METHODS

A descriptive study using the Dillman approach and informed by the Knowledge to Action framework was conducted.

RESULTS

Twenty-six health care providers responded to the survey; 62% reported using the violence risk assessment tool available on their unit, but not on a daily basis. Common barriers were lack of knowledge of the tool, lack of resources and time, and negative attitudes toward patients. 42% of participants indicated the need for further training on violence risk assessment.

CONCLUSION

Despite high exposure to violence, health professionals were not conducting daily risk assessments. The barriers and facilitators identified provide direction for interventions that are necessary if the daily use of violence risk assessment tools is to be increased.
