Risk factors associated with challenging behaviour in people with profound intellectual and multiple disabilities

Challenging behaviour, the application of restrictive measures and psychotropic drug prescription in people with intellectual disabilities

BACKGROUND

Prescribing of psychotropic drugs (PDs) and applying restrictive measures are both frequently used in managing challenging behaviour of people with intellectual disabilities (ID), which is not always according to guidelines or good clinical practice.

AIMS

This study aimed to investigate the potential triangular relationship between challenging behaviour, the application of restrictive measures and PD prescription.

METHODS AND PROCEDURES

In this cross-sectional study, data on challenging behaviour, PD prescription and restrictive measures were collected. We defined and compared four mutually exclusive groups of participants.

OUTCOMES AND RESULTS

Challenging behaviour in the group in whom one or more PD were prescribed as a restrictive measures (PDRM) was more severe than in the other three groups. More severe challenging behaviour, a higher number of antipsychotics, antidepressants and anxiolytics/hypnotics prescriptions, a lower dosage, and more application of domotics as restrictive measure was shown in the PDRM compared to the group in whom PDs were prescribed according to guidelines (PDNRM).

CONCLUSIONS AND IMPLICATIONS

We did not find indications for a triangular relationship of challenging behaviour, the application of restrictive measures and PD prescriptions. Future longitudinal research is needed to better understand this complex relationship and should investigate the indication and the effect of treatment. WHAT THIS PAPER ADDS?: This study is a first exploration of the potential triangular relationship between symptoms of challenging behaviour, psychotropic drug (PD) prescription, and the application of restrictive measures. Prescribing PDs and applying restrictive measures are two interventions which are commonly used to manage challenging behaviour in people with intellectual disabilities. Both have been subject of research separately in recent years. However, it is conceivable that the PD prescription in treatments for challenging behaviour could be a substitute for another form of a restrictive measure, for example a physical or mechanical restraint. For this purpose, we defined and compared four mutually exclusive groups of participants. We found no indication for this triangular relationship. On the other hand, we found the highest severity of challenging behaviour in the group who used PDs as restrictive measure next to other restrictive measures. Our results may suggest that both prescribing PDs and applying non-pharmacological restrictive measures are used simultaneously in managing challenging behaviour, are not sufficiently implemented or effective.

Integrative Care for Challenging Behaviors in People with Intellectual Disabilities to Reduce Challenging Behaviors and Inappropriate Psychotropic Drug Prescribing Compared with Care as Usual: A Cluster-Randomized Trial

People with intellectual disabilities (IDs) often present with challenging behaviors (CBs) mostly due to inappropriate environments and mental and physical disorders. Integrative care is recommended to address CBs. However, in clinical practice, psychotropic drugs are often prescribed off-label for CBs, although the effectiveness is unclear, and side effects frequently occur. We conducted a cluster-randomized controlled study to investigate the effect of integrative care provided by a collaboration of an ID specialized mental healthcare team and participants' own ID service providers' care team on reducing CBs and inappropriate off-label psychotropic drug prescriptions compared with care as usual. Participants (N = 33, aged 19-81 years) had a moderate, severe, or profound intellectual disability and used off-label psychotropic drugs. The primary outcome measures were the Aberrant Behavior Checklist and the total dose of psychotropic drug prescriptions. At the study endpoint of 40 weeks, we found no effect of the intervention on the total ABC score and on the total dose of psychotropic drug prescriptions. In the intervention group, however, the psychotropic drug dose decreased significantly, while CBs did not change. The small sample size and not-completed interventions due to organizational problems may have affected our findings. This study illustrates the difficulties in the implementation of integrative care.

Supporters' experiences of sensory characteristics of children with profound intellectual and multiple disabilities in after-school daycare centres: A qualitative study

AIM

To examine how supporters working at after-school daycare centres, who are involved in the lives of children with profound intellectual and multiple disabilities in the community, pay attention to the sensory characteristics of these children and provide support.

DESIGN

A qualitative descriptive design.

METHODS

Data were collected through semi-structured interviews with 20 supporters in after-school daycare centres. Interview transcripts were analysed via qualitative content analysis.

RESULTS

The participants' years of involvement in supporting children with profound intellectual and multiple disabilities ranged from 0.5 to 40 years, with an average of 9.8 years. Data were classified into 68 subcategories, 11 categories and three themes: understanding sensory characteristics and devising support, systematic support and challenges supporting the children. Supporters dealt with physical complications and cooperated with other caregivers to understand and respond to children's sensory characteristics. Difficulties dealing with sensory characteristics, challenges due to the supporters' own characteristics and challenges with the facility's infrastructure were identified. The findings could guide sensory characteristics considerations and support systems in after-school daycare facilities for children with profound intellectual and multiple disabilities. Both support content and challenges in supporting these children were identified.

Sleep-wake monitoring of people with intellectual disability: Examining the agreement of EMFIT QS and actigraphy

BACKGROUND

Gaining insight into sleep-wake patterns of persons with intellectual disabilities is commonly done using wrist actigraphy. For some people, contactless alternatives are needed. This study compares a contactless bed sensor with wrist actigraphy to monitor sleep-wake patterns of people with moderate to profound intellectual disabilities.

METHOD

Data were collected with EMFIT QS (activity and presence) and MotionWatch 8/Actiwatch 2 (activity, ambient light, and event marker/sleep diary) for 14 nights in 13 adults with moderate-profound intellectual disabilities residing in intramural care.

RESULTS

In a care-as-usual setting, EMFIT QS and actigraphy assessment show little agreement on sleep-wake variables.

CONCLUSION

Currently, EMFIT QS should not be considered an alternative to wrist actigraphy for sleep-wake monitoring. Further research is needed into assessing sleep-wake variables using (contactless) technological devices and how the data should be interpreted within the care context to achieve reliable and valid information on sleep-wake patterns of people with intellectual disabilities.

A review of the use of psychotropic medication to address challenging behaviour in neurodevelopmental disorders

Engagement in challenging behaviour (e.g., aggression, self-injury) is reported to occur in neurodevelopmental disorders such as intellectual disabilities (ID), autism spectrum disorder (ASD), and fragile X syndrome (FXS). Common interventions to address these behaviours include both behavioural and pharmacological approaches. Although psychotropic medications are commonly used to address challenging behaviour in ID, ASD, and FXS, demonstration of the effectiveness of treatment is limited. Furthermore, research examining interaction effects between psychotropic medication, challenging behaviour, and environmental events within specific neurodevelopmental disorders such as ID, ASD, and FXS is scarce. The purpose of this chapter is to provide an overview of challenging behaviour within ID, ASD, and FXS and of the effectiveness of psychotropic medication as an intervention for challenging behaviour within these neurodevelopmental disorders. Finally, research examining how psychotropic medication may impact the relationship between challenging behaviour and environmental events is reviewed.

Behavioural sleep problems in children and adults with intellectual disabilities: An integrative literature review

BACKGROUND

People with intellectual disabilities are more likely to experience sleep problems, which can affect quality of life, physical health, mental health and well-being.

METHODS

An integrative literature review was conducted to investigate what is known about behavioural sleep disturbances in people with an intellectual disability. The search used the following databases: Scopus, PsycInfo and Cinahl, to find papers published since 2015.

RESULTS

Within intellectual disability research, sleep appears as a common issue due to its high prevalence, negative relationships with an individual's physical and mental health, their quality of life, and impact of sleep problems on family or carers. The growing evidence base appears to support the use of behavioural, lifestyle and pharmacological interventions to improve sleep in people with an intellectual disability.

CONCLUSION

A wide array of literature provides evidence that people with intellectual disabilities are affected by and need support with their sleep.

Difficulties in Addressing Diagnostic, Treatment and Support Needs in Individuals with Intellectual Disability and Persistent Challenging Behaviours: A Descriptive File Study of Referrals to an Expertise Centre

Service providers may experience difficulties in providing appropriate care to optimize the functioning of individuals with intellectual disability and challenging behaviour. External consultation to identify and address the unmet support needs underlying the behaviour may be beneficial. Applying the multidimensional American Association Intellectual and Developmental Disabilities (AAIDD) model may facilitate this approach. We aimed to describe the content and outcomes of consultation for individuals with intellectual disability and challenging behaviour referred to the Dutch Centre for Consultation and Expertise in relation to the AAIDD model. Interventions were based on the clients' diagnostic, treatment, and support needs and were categorized according to the five dimensions of the AAIDD model. Outcomes of the consultations were assessed based on reports in the file and rated as 'clear improvement', 'improvement' or 'no improvement or deterioration'. In two-thirds of the 104 studied files, consultees were satisfied with the improvement in functioning. Interventions targeted the difficulties of the service providers in supporting their clients and were most often applied within the Health and Context dimensions of the AAIDD model. We may conclude that consultation of an expert team may be valuable to support the care providers, and the use of the AAIDD model may be helpful to address the unmet needs to improve the functioning of individuals with challenging behaviour.

Reliable assessment of pain behaviour in adults with profound intellectual and multiple disabilities: The development of an instruction protocol

BACKGROUND

Persons with profound intellectual and multiple disabilities (PIMD) are vulnerable when it comes to experiencing pain. Reliable assessment of pain-related behaviour in these persons is difficult. Aim To determine how pain items can be reliably scored in adults with PIMD.

METHODS

We developed an instruction protocol for the assessment of pain-related behaviour in four phases. We used videos of 57 adults with PIMD during potentially painful situations. The items were assessed for inter-rater reliability (Cohen's kappa or percentage of agreement).

RESULTS

The developed instruction protocol appeared to be adequate. Twelve items had satisfactory inter-rater reliability (n = 9: .30-1.00; n = 3: 85%-100%).

DISCUSSION

Calibrating and adjustments to the instructions and item set appeared to be crucial to reliably score 12 items in adults with PIMD. Further research should focus on creating an assessment instrument based on these reliably scored items.

Withdrawing Antipsychotics for Challenging Behaviours in Adults with Intellectual Disabilities: Experiences and Views of Prescribers

International current best practice recommends the discontinuation of antipsychotics for challenging behaviours in people with intellectual disabilities (ID), due to lack of evidence of efficacy and risks of harmful side-effects. In clinical practice, discontinuation may be difficult. The aim of this study was to gain insight into prescribers' practice by investigating their experiences with the discontinuation of long-term antipsychotics for challenging behaviour. From professionals' associations thirty-four registered ID physicians, psychiatrists and specialist mental healthcare nurses were recruited who completed an online questionnaire in this survey-study. Almost all participants had attempted to deprescribe antipsychotics for their patients with ID. Sixty-five percent of participants achieved complete discontinuation in 0-25% of their patients, but none in over 50%. Barriers were a lack of non-pharmaceutical treatments for challenging behaviours and caregivers' and/or family concern. Seventy percent of participants indicated that their institutions had encouraged implementing their discontinuation policies in line with the new Dutch Act on Involuntary care and a new Dutch multidisciplinary guideline on problem behaviour in adults with ID. Support and facilitation of clinicians from institutions' managers and political and professional bodies may be helpful in further implementation of best practice in the treatment of challenging behaviour in people with ID.

Assessment of Challenging Behavior Exhibited by People with Intellectual and Developmental Disabilities: A Systematic Review

The assessment of challenging behavior exhibited by people with intellectual and developmental disabilities is essential for the planning of prevention and intervention programs. This review aimed to identify and analyze the standardized instruments that exclusively focus on the assessment of challenging behavior. We identified and organized 141 articles into four categories: original instrument studies, validation studies, relational studies, and intervention studies. The results identified 24 instruments that generally show high-quality psychometric properties and other utilities beyond the observation of the presence of challenging behavior and diagnostic categorization. Age, level of adaptive behavior, disability, presence of autism spectrum disorder, and medication are some of the variables that were found to be possibly related to the occurrence of challenging behavior. Additionally, the results suggest that interventions focused on supporting positive behavior or providing training on behavior to professionals and caregivers significantly reduced the occurrence of these behaviors. Instruments that help us to understand and measure the challenging behavior exhibited by people with intellectual and developmental disabilities are essential for the design of effective evaluation and intervention protocols.

Challenging behaviors among students with severe developmental disabilities in Saudi Arabia: Impact of socio-demographic differences

This study aimed to explore the prevalence of challenging behaviors (CBs) associated with students with severe developmental disabilities (SDDs) as rated by their teachers. The study also attempted to examine whether the occurrence and intensity of CBs might depend on certain socio-demographic variables. Data was collected using a questionnaire to rate the prevalence of CBs in 687 students with SDDs. Results indicate that social problems, stereotypical behaviors, and disobedient behaviors were estimated to be the most prevalent of CBs among such students. Positive correlations were confirmed between the type of disability, gender, age, school grade, educational placement, and the prevalence of CBs among students with SDDs. Implications for educational practice and recommendations for future research are discussed.

Inventory of assessment practices in people with profound intellectual and multiple disabilities in three European countries

Background

Knowledge about the quality of assessment methods used in the support of people with profound intellectual and multiple disabilities (PIMD) is scarce. This study aimed to provide an overview of the assessment methods used in practice and to examine whether these instruments were studied for their psychometric properties for people with PIMD.

Method

Professionals (N = 148) from three European countries completed a survey on assessment practices. We performed a literature search to find information about the psychometric properties of the instruments that were identified in the survey.

Results

Of the participants, 78.1% used assessments that were not developed for people with PIMD. Documentation on psychometric properties was found for 8 out of 116 instruments.

Conclusions

Most of the instruments in use were not designed for people with PIMD, and information about their quality is lacking. Guidelines are needed regarding the use and development of assessment methods for people with PIMD.

Prevalence of Challenging Behaviour in Adults with Intellectual Disabilities, Correlates, and Association with Mental Health

Purpose of Review

To summarise findings about the prevalence and correlates of challenging behaviour in adults with intellectual disabilities from robust research. We also describe findings on the interplay between challenging behaviour and mental health.

Recent Findings

Recent studies that have utilised psychometrically evaluated tools, with clear operational definitions, show similar findings on the prevalence of challenging behaviour of about 1 in every 5–6 adults known to services. We describe common correlates identified such as communication impairments, severity of intellectual disability, and living in institutional settings or congregate care. We also describe the complex and multifaceted relationship between challenging behaviour and mental health.

Summary

Based on recent studies, we propose a revised framework model to help understand challenging behaviour. We propose a number of areas where more research is required, particularly the development of risk tools clinicians can utilise in practice.

Framework for assessing individuals with rare genetic disorders associated with profound intellectual and multiple disabilities (PIMD): the example of Phelan McDermid Syndrome

BACKGROUND

Specialized strategies are needed to understand the complex neuropsychological impairments reported in individuals with profound intellectual and multiple disabilities (PIMD) associated with rare genetic disorders.

METHODS

This narrative review focuses on assessment of individuals with Phelan-McDermid Syndrome (PMS) as a condition commonly associated with PIMD. Published case series and prospective studies were reviewed to evaluate approaches to cognitive, language, motor/sensory, and behavioral domains. This review is framed using general principles for neuropsychological evaluation in PIMD.

RESULTS

Neuropsychological assessment domains and tools varied across published reports. Adaptive behavior measures, out-of-range developmental assessments, and social-communication measures were commonly used. Available findings were used to shape a recommended framework with potential to improve measurement of clinical outcomes and advance scientific discovery.

CONCLUSIONS

The recommended framework outlines an inter-disciplinary and multimodal neuropsychological assessment process relying on modified standardized assessments, functional assessments, and caregiver/informant reports when evaluating individuals with PIMD. Arrested development and skill variability/regression are also discussed as additional, important considerations in neuropsychological evaluation of individuals with PIMD and rare genetic disorders.

Self-injurious behaviour in people with intellectual disability and autism spectrum disorder

PURPOSE OF REVIEW

This review summarises the recent trends in research in the field of self-injurious behaviour in people with intellectual disability and autism spectrum disorder.

RECENT FINDINGS

New data on incidence, persistence and severity add to studies of prevalence to indicate the large scale of the clinical need. A number of person characteristics have been repeatedly identified in prevalence and cohort studies that: can be considered as risk markers (e.g. stereotyped behaviour, autism spectrum disorder) and indicate possible causal mechanisms (e.g. sleep disorder, anxiety). Studies have started to integrate traditional operant learning paradigms with known person characteristics and reviews and meta-analyses of applied behaviour analytic procedures can now inform practice.

SUMMARY

Despite these positive developments interventions and appropriate support falls far short of the required need. Expansions in applied research are warranted to develop and evaluate innovative service delivery models that can translate knowledge of risk markers and operant learning paradigms into widespread, low cost routine clinical practice. Alongside this, further pure research is needed to elucidate the direction of causality of implicated risk factors, in order to understand and intervene more effectively in self-injury.

Using Adapted Dialectical Behavioral Therapy to Treat Challenging Behaviors, Emotional Dysregulation, and Generalized Anxiety Disorder in an Individual With Mild Intellectual Disability

Individuals with intellectual disability (ID) are at increased risk of presenting challenging behaviors and comorbid mental illness. Preliminary findings show decreased challenging behaviors and overall increased functioning in individuals with ID and mental health problems who receive adapted dialectical behavior therapy (DBT). However, more research and documentation on how to adapt DBT in this population is warranted given that DBT is a promising intervention in individuals with ID. This article presents the case of an individual with mild ID who received adapted DBT for the treatment of challenging behaviors, emotional dysregulation, and generalized anxiety disorder. Treatment lasted 1 year and was conducted in a residential facility for individuals with ID. Improvement of symptoms and decrease in frequency of challenging behaviors were observed throughout the case. This case study demonstrates the potential utility of adapted DBT for individuals with ID and underscores the importance of teaching skills to clients with ID to help them become agents of their own change.

Relabelling behaviour. The effects of psycho-education on the perceived severity and causes of challenging behaviour in people with profound intellectual and multiple disabilities

BACKGROUND

Prevalence rates of challenging behaviour are high in children and adults with profound intellectual and multiple disabilities (PIMD). Moreover, many of these behaviours are observed daily. Direct support staff report that most challenging behaviour identified has little impact on the person with PIMD and attribute challenging behaviour in children and adults with PIMD mainly to a biomedical model. The purpose of this study was to evaluate whether an intervention (psycho-education) had any effect on direct support staff's assessment of challenging behaviour in terms of its severity and their biomedical causal explanations (attributions) for this behaviour.

METHOD

A stepped wedge study design was used to evaluate the effects of a psycho-education intervention on the perceived severity and the attributions offered for challenging behaviour of people with PIMD by 198 direct support staff. We used questionnaires assessing the perceived severity of challenging behaviour and staff views of its causes. Data on the dependent variables were collected at four 1-month intervals.

RESULTS

The intervention was found to have an effect on the perceived severity of challenging behaviour identified in people with PIMD in the sense that staff generally scored challenging behaviour as more severe in its consequences after the intervention. However, this effect was very small. No significant effects were found in terms of reduction in the biomedical scale scores.

CONCLUSION

No evidence for the effectiveness of a psycho-educational approach on the assessment of challenging behaviour in terms of severity and the biomedical attributions for behaviour was found. More research is required to explore further the effects of more elaborate training using methods to enable direct support staff to reflect on the behaviour of people with PIMD and on their own behaviour.
