Adults with intellectual disabilities: prevalence, incidence and remission of aggressive behaviour and related factors

Unmasking the Struggle: A Scoping Review Exploring Post-Traumatic Stress Symptoms in Caregivers of Individuals with Neurodevelopmental, Psychiatric and Neurocognitive Disorders

The impact of caregiving on caregivers' mental health is typically considered within the caregiver stress and burden literature; however, more recently, research has investigated the experience of post-traumatic stress symptoms (PTSS) in caregivers. As an emerging area of research, it is timely to conduct a scoping review to map the existing literature in relation to PTSS among adult caregivers of children and adults with neurodevelopmental disorders (NDD), neurocognitive disorders, and psychiatric disorders. The scoping review was conducted using Preferred Reporting Items of Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines and Arksey and O'Malley's five-stage methodology framework. Published and unpublished gray literature between 2005 and 2022 was included in the scoping review. Nine thousand one hundred and twenty-five studies were originally identified for screening and 22 studies were selected for inclusion in the final review. Trauma and PTSS experienced by NDD caregivers were related to news breaking, NDD diagnosis, and behavioral issues, whereas caregivers of individuals with psychosis reported aggression and violence as traumatic events. Studies showed that up to half of caregivers reported PTSS, although no conclusions could be drawn about prevalence rates. A wide variety of tools measuring PTSS were used across the 22 studies. Many symptoms of PTSS were reported by caregivers, and cognitive appraisals were associated with PTSS in caregivers. The findings highlight the importance of recognizing the impact of trauma in caregiver mental health and the potential value of using traumatic stress frameworks with these populations. Research should be expanded to establish prevalence rates and to examine the long-term impact of trauma on caregiving as caregivers and care recipients age.

The cumulative impact of attention deficit hyperactivity disorder, autism and intellectual disability for young people

BACKGROUND

Neurodevelopmental conditions frequently co-occur. The aim of this paper was to determine whether there is a cumulative association between (1) the number of neurodevelopmental conditions, specifically hyperkinetic disorder (hereafter referred to as attention deficit hyperactivity disorder), autism spectrum disorder (hereafter referred to as autism) and intellectual disability, and (2) behavioural and socio-emotional problems and the level of clinician-rated functioning for young males and females.

METHODS

In this cross-sectional study, diagnostic information, caregiver-rated behavioural and socio-emotional data (as conceptualised by the Strengths and Difficulties Questionnaire) and clinician-rated functioning scores (as conceptualised by the Children's Global Assessment Scale) were extracted from electronic patient records for 2768 young people aged 3-17 years (mean = 11.55, SD = 3.46). All data were extracted at baseline, that is, at the time the young person was diagnosed with attention deficit hyperactivity disorder, autism and/or an intellectual disability. Ordinal regression analyses tested associations between the number of neurodevelopmental conditions met (i.e. 1, 2 or 3) and behavioural and socio-emotional outcomes and functioning.

RESULTS

After controlling for age and biological sex, the number of neurodevelopmental conditions was associated with higher levels of inattention/hyperactivity and peer problems, lower levels of prosocial behaviour and poorer clinician-rated functioning. Although these findings were consistent for males, a cumulative association was not identified for females, except for clinician-rated functioning.

CONCLUSIONS

For young people, the presence of multiple neurodevelopmental conditions may have a cumulative impact across domains, but this may differ between males and females.

Process evaluation of a parenting intervention for pre-schoolers with intellectual disabilities who display behaviours that challenge in the UK

BACKGROUND

Stepping Stones Triple P (SSTP) is a complex parent-mediated intervention aimed to reduce behaviours that challenge in children with moderate to severe intellectual disabilities, aged 30-59 months.

METHODS

To formulate a comprehensive understanding of SSTP implementation in the UK, we conducted a process evaluation collecting stakeholder views and considering intervention fidelity, dose, reach, delivery adaptations, and acceptability.

RESULTS

Fidelity and quality of delivery ratings were high. Parents perceived SSTP as valuable, reporting increased parental confidence and understanding of the child's behaviours. However, only 30% of families received an adequate dose of the intervention. Parents who only received treatment as usual described feeling abandoned by current services. Service managers emphasised the importance of availability of resources and therapist training for successful intervention delivery.

CONCLUSIONS

SSTP supports effective management of early-onset behaviours that challenge. Further work is needed to ensure equitable access to the intervention across health and social care services.

Emotional Reactions of Professionals to Challenging Behaviors in People with Intellectual and Developmental Disability

Professionals working with people with intellectual and developmental disability (IDD) can be exposed to challenging behaviors (CBs), which may result in professionals exhibiting emotional reactions that can impact their practices. This study examined these reactions and analyzed how they are influenced by the individual characteristics of people with IDD (gender, age, and level of IDD) and the variables related to CB (type of behavior and its frequency and behavioral function). A total of 125 professionals assessed 293 people with IDD who exhibited CBs. The professionals were asked to complete the Behavior Problems Inventory-Short Form, the Emotional Reactions to Challenging Behavior Scale, and the Questions About Behavior Function measure. It was revealed that positive emotional reactions predominated over negative ones. Significant results were found regarding the level of disability and the age of people with IDD. Emotional reactions were related to the severity of CBs, especially self-injurious and aggressive/destructive behavior, as well as certain behavioral functions. The severity of CBs and the age of people with IDD emerge as key predictors of the emotional reactions of professionals. In short, these reactions vary according to different variables, highlighting the importance of interventions that address professionals' emotional needs.

Effectiveness of deep brain stimulation on refractory aggression in pediatric patients with autism and severe intellectual disability: meta-analytic review

Some patients with autism and severe intellectual disability may experience uncontrolled aggression, causing serious injury or harm to others, and the therapeutic ineffectiveness of traditional pharmacological and behavioral treatment may aggravate symptoms. Deep brain stimulation (DBS) has been tested in patients with little evidence in children and adolescents. Therefore, we analyzed the efficacy and safety of DBS in refractory aggression in pediatric subjects with autism (ASD) and severe intelligence deficit (ID).Methods A meta-analytic review of Web of Science (WOS) and Scopus articles, following Prisma criteria. A total of 555 articles were identified, but after applying the inclusion criteria, only 18 were analyzed. The review of the registries and the extraction of information was performed by 2 independent groups, to reduce the evaluator's bias. For the description of the results, pediatric patients with ASD or ID present in each registry, with an application of specialized scales (Overt aggression scale, OAS, and THE modified version of the OAS, MOAS) pre and post-DBS, with a clinical follow-up of at least 12 months, were considered valid. Clinical improvement was calculated using tests of aggressiveness. In each registry with available data and then pooling the means of all patients in the OAS and MOAS, the effect size of DBS (overall and per study) was estimated. Finally, the adapted NOS scale was applied to rate the studies' quality and level of bias.Results In the studies analyzed, 65/100 were pediatric patients, with a mean age of 16.8 years. Most of the studies were conducted in South America and Europe. In all teams, aggressive behavior was intractable, but only 9 groups (53/65) applied specialized scales to measure aggressiveness, and of these, only 51 subjects had a follow-up of at least 12 months. Thus, in 48/51 a clinical improvement of patients was estimated (94.2%), with a considerable overall effect size (OAS: d = 4.32; MOAS: d = 1.46). However, adverse effects and complications were found in 13/65 subjects undergoing DBS. The brain target with the most evidence and the fewest side effects was the posteromedial hypothalamic nuclei (pHypN). Finally, applying the adapted NOS scale, quality, and bias, only 9 studies show the best indicators.Conclusion An optimal level of efficacy was found in only half of the publications. This is mainly due to design errors and irrelevant information in the reports. We believe that DBS in intractable aggressiveness in children and adolescents with ASD and severe ID can be safe and effective if working groups apply rigorous criteria for patient selection, interdisciplinary assessments, objective scales for aggressiveness, and known surgical targets.

Stimulus Avoidance Assessment: A Systematic Literature Review

Board certified behavior analysts are ethically required to first address destructive behavior using reinforcement-based and other less intrusive procedures before considering the use of restrictive or punishment-based procedures (ethics standard 2.15; Behavior Analyst Certification Board, 2020). However, the inclusion of punishment in reinforcement-based treatments may be warranted in some cases of severe forms of destructive behavior that poses risk of harm to the client or others. In these cases, behavior analysts are required to base the selection of treatment components on empirical assessment results (ethics standard 2.14; Behavior Analyst Certification Board, 2020). One such preintervention assessment is the stimulus avoidance assessment (SAA), which allows clinicians to identify a procedure that is likely to function as a punisher. Since the inception of this assessment approach, no studies have conducted a systematic literature review of published SAA cases. These data may be pertinent to examine the efficacy, generality, and best practices for the SAA. The current review sought to address this gap by synthesizing findings from peer-reviewed published literature including (1) the phenomenology and epidemiology of the population partaking in the SAA; (2) procedural variations of the SAA across studies (e.g., number of series, session length); (3) important quality indicators of the SAA (i.e., procedural integrity, social validity); and (4) how the SAA informed final treatment efficacy. We discuss findings in the context of the clinical use of the SAA and suggest several avenues for future research.

Clinical and cost-effectiveness of an adapted intervention for preschoolers with moderate to severe intellectual disabilities displaying behaviours that challenge: the EPICC-ID RCT

Background

Stepping Stones Triple P is an adapted intervention for parents of young children with developmental disabilities who display behaviours that challenge, aiming at teaching positive parenting techniques and promoting a positive parent-child relationship.

Objective

To evaluate the clinical and cost-effectiveness of level 4 Stepping Stones Triple P in reducing behaviours that challenge in children with moderate to severe intellectual disabilities.

Design, setting, participants

A parallel two-arm pragmatic multisite single-blind randomised controlled trial recruited a total of 261 dyads (parent and child). The children were aged 30-59 months and had moderate to severe intellectual disabilities. Participants were randomised, using a 3 : 2 allocation ratio, into the intervention arm (Stepping Stones Triple P; n = 155) or treatment as usual arm (n = 106). Participants were recruited from four study sites in Blackpool, North and South London and Newcastle.

Intervention

Level 4 Stepping Stones Triple P consists of six group sessions and three individual phone or face-to-face contacts over 9 weeks. These were changed to remote sessions after 16 March 2020 due to the coronavirus disease 2019 pandemic.

Main outcome measure

The primary outcome measure was the parent-reported Child Behaviour Checklist, which assesses the severity of behaviours that challenge.

Results

We found a small non-significant difference in the mean Child Behaviour Checklist scores (-4.23, 95% CI -9.98 to 1.52, p = 0.146) in the intervention arm compared to treatment as usual at 12 months. Per protocol and complier average causal effect sensitivity analyses, which took into consideration the number of sessions attended, showed the Child Behaviour Checklist mean score difference at 12 months was lower in the intervention arm by -10.77 (95% CI -19.12 to -2.42, p = 0.014) and -11.53 (95% CI -26.97 to 3.91, p = 0.143), respectively. The Child Behaviour Checklist mean score difference between participants who were recruited before and after the coronavirus disease 2019 pandemic was estimated as -7.12 (95% CI -13.44 to -0.81) and 7.61 (95% CI -5.43 to 20.64), respectively (p = 0.046), suggesting that any effect pre-pandemic may have reversed during the pandemic. There were no differences in all secondary measures. Stepping Stones Triple P is probably value for money to deliver (-£1057.88; 95% CI -£3218.6 to -£46.67), but decisions to roll this out as an alternative to existing parenting interventions or treatment as usual may be dependent on policymaker willingness to invest in early interventions to reduce behaviours that challenge. Parents reported the intervention boosted their confidence and skills, and the group format enabled them to learn from others and benefit from peer support. There were 20 serious adverse events reported during the study, but none were associated with the intervention.

Limitations

There were low attendance rates in the Stepping Stones Triple P arm, as well as the coronavirus disease 2019-related challenges with recruitment and delivery of the intervention.

Conclusions

Level 4 Stepping Stones Triple P did not reduce early onset behaviours that challenge in very young children with moderate to severe intellectual disabilities. However, there was an effect on child behaviours for those who received a sufficient dose of the intervention. There is a high probability of Stepping Stones Triple P being at least cost neutral and therefore worth considering as an early therapeutic option given the long-term consequences of behaviours that challenge on people and their social networks.

Future work

Further research should investigate the implementation of parenting groups for behaviours that challenge in this population, as well as the optimal mode of delivery to maximise engagement and subsequent outcomes.

Identifying individuals with intellectual disability who access mental health support and are at high risk for adverse clinical outcomes: cohort study

BACKGROUND

People with intellectual disability often experience aggressive challenging behaviour and mental health issues. It can be difficult to identify those who are at higher risk of adverse clinical outcomes when in clinical care.

AIMS

To characterise potential subgroups in adults with intellectual disability referred to mental health services in those presenting with aggressive behaviour or common mental disorders (CMDs).

METHOD

There were 836 adults (≥18 years) with intellectual disability and a record of aggressive challenging behaviour, and 205 patients with intellectual disability and CMDs, who were seen in specialist mental health services over a 5-year period. Cluster analysis was used to define patient characteristics associated with clinical outcome.

RESULTS

Distinct patient groups with differentiated profiles were observed in people with intellectual disability displaying aggressive challenging behaviour, and in those presenting with CMDs. Characteristics of the aggressive behaviour group who experienced adverse outcomes included being <30 years old, being male, more mentions of aggression and agitation in their clinical record, a diagnosis of pervasive developmental disorder and prescription of psychotropic medication. Characteristics of the CMD cluster that experienced adverse clinical outcomes were being older, being a White male, having a mild intellectual disability and physical health concerns.

CONCLUSIONS

People with intellectual disability who experience adverse clinical outcomes can be identified with a cluster analysis approach of common features, but differ by clinical presentation. This could be used not only to stratify this clinically heterogeneous population in terms of response to interventions, but also improve precision in the development of tailored interventions.

Non-pharmacological and pharmacological interventions for the reduction or prevention of topographies of behaviours that challenge in people with intellectual disabilities: a systematic review and meta-analysis of randomised controlled trials

BACKGROUND

People with intellectual disability show a high prevalence of behaviours that challenge. Clinical guidelines recommend that such behaviour should first be treated with non-pharmacological interventions, but research suggests off-label pharmaceuticals are commonly used. We aimed to evaluate the efficacy of non-pharmacological and pharmacological interventions for topographies of behaviours that challenge drawn from randomised controlled trials (RCTs).

METHODS

In this systematic review and meta-analysis, we searched PsycINFO, MEDLINE, Embase, CINAHL, and CENTRAL databases for RCT studies assessing an intervention (pharmacological or non-pharmacological) for behaviours that challenge (self-injury behaviour, aggression, destruction of property, irritability, and a composite overall measure) in participants with intellectual disability. The primary aim was to assess the efficacy of non-pharmacological and pharmacological interventions on behaviours that challenge. Secondary aims were to evaluate how effects varied over time and whether intervention, methodological, and participant characteristics moderate efficacy. We extracted standard mean difference (SMD) effect sizes (Cohen's d) from eligible studies and meta-analysed the data using a series of random effects models and subgroup analyses. This study was registered with PROSPERO 2021, CRD4202124997.

FINDINGS

Of 11 912 reports identified, 82 studies were included. 42 (51%) studies assessed non-pharmacological interventions and 40 (49%) assessed pharmacological interventions. Across all studies, 4637 people with intellectual disability aged 1-84 years (mean age 17·2 years) were included. 2873 (68·2%) were male, 1339 (28·9%) were female, and for 425 (9·2%) individuals, data on gender were not available. Data on ethnicity were unavailable. Small intervention effects were found for overall behaviours that challenge at post-intervention (SMD -0·422, 95% CI -0·565 to -0·279), overall behaviours that challenge at follow-up (-0·324, -0·551 to -0·097), self-injury behaviour at post-intervention (-0·238, -0·453 to -0·023), aggression at post-intervention (-0·438, -0·566 to -0·309), and irritability at post-intervention (-0·255, -0·484 to -0·026). No significant differences between non-pharmacological and pharmacological interventions were found for any topography of behaviours that challenge (all p>0·05).

INTERPRETATION

A broad range of interventions for behaviours that challenge are efficacious with small effect sizes for people with intellectual disability. These findings highlight the importance of precision in the measurement of behaviours that challenge, and when operationalising intervention components and dosages.

Pain Management in the Most Vulnerable Intellectual Disability: A Review

This review is made up of two parts; the first part discussing intellectual disability (ID) in general, while the second part covers the pain associated with intellectual disability and the challenges and practical tips for the management of pain associated with (ID). Intellectual disability is characterized by deficits in general mental abilities, such as reasoning, problem solving, planning, abstract thinking, judgment, academic learning, and learning from experience. ID is a disorder with no definite cause but has multiple risk factors, including genetic, medical, and acquired. Vulnerable populations such as individuals with intellectual disability may experience more pain than the general population due to additional comorbidities and secondary conditions, or at least the same frequency of pain as in the general population. Pain in patients with ID remains largely unrecognized and untreated due to barriers to verbal and non-verbal communication. It is important to identify patients at risk to promptly prevent or minimize those risk factors. As pain is multifactorial, thus, a multimodal approach using both pharmacotherapy and non-pharmacological management is often the most beneficial. Parents and caregivers should be oriented to this disorder, given adequate training and education, and be actively involved with the treatment program. Significant work to create new pain assessment tools to improve pain practices for individuals with ID has taken place, including neuroimaging and electrophysiological studies. Recent advances in technology-based interventions such as virtual reality and artificial intelligence are rapidly growing to help give patients with ID promising results to develop pain coping skills with effective reduction of pain and anxiety. Therefore, this narrative review highlights the different aspects regarding the current status of the pain associated with intellectual disability, with more emphasis on the recent pieces of evidence for the assessment and management of pain among populations with intellectual disability.

Stress-Induced Auto-Cannibalism in Patients With a History of Moderate Traumatic Brain Injury

A traumatic brain injury (TBI) is a significant factor in injury-related deaths in the United States and may lead to complex psychological disorders. Auto-cannibalism as a sequela of a TBI has yet to be reported in the literature. The current literature regarding such behavior is often associated with psychosis, intellectual disability, or substance use. A 35-year-old male had a past medical history significant for a TBI a decade ago. He was transferred to the emergency department due to a self-inflicted wound. The patient had been scratching his arms and legs for the last few months and displayed an intense new pattern of self-destructive behavior in the past week. He went through surgical wound debridement and psychiatric evaluation before he was discharged home. This case depicts the importance of regular, long-term psychiatric, and neurological follow-up for patients sustaining TBIs, regardless of whether or not they were previously deemed stable. A greater understanding of many factors leading to self-destructive behavior following TBIs is needed to improve patient outcomes.

Behavioural and cognitive-behavioural interventions for outwardly directed aggressive behaviour in people with intellectual disabilities

BACKGROUND

Outwardly directed aggressive behaviour in people with intellectual disabilities is a significant issue that may lead to poor quality of life, social exclusion and inpatient psychiatric admissions. Cognitive and behavioural approaches have been developed to manage aggressive behaviour but the effectiveness of these interventions on reducing aggressive behaviour and other outcomes are unclear. This is the third update of this review and adds nine new studies, resulting in a total of 15 studies in this review.

OBJECTIVES

To evaluate the efficacy of behavioural and cognitive-behavioural interventions on outwardly directed aggressive behaviour compared to usual care, wait-list controls or no treatment in people with intellectual disability. We also evaluated enhanced interventions compared to non-enhanced interventions.

SEARCH METHODS

We used standard, extensive Cochrane search methods. The latest search date was March 2022. We revised the search terms to include positive behaviour support (PBS).

SELECTION CRITERIA

We included randomised and quasi-randomised trials of children and adults with intellectual disability of any duration, setting and any eligible comparator.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcomes were change in 1. aggressive behaviour, 2. ability to control anger, and 3. adaptive functioning, and 4.

ADVERSE EFFECTS

Our secondary outcomes were change in 5. mental state, 6. medication, 7. care needs and 8. quality of life, and 9. frequency of service utilisation and 10. user satisfaction data. We used GRADE to assess certainty of evidence for each outcome. We expressed treatment effects as mean differences (MD) or odds ratios (OR), with 95% confidence intervals (CI). Where possible, we pooled data using a fixed-effect model.

MAIN RESULTS

This updated version comprises nine new studies giving 15 included studies and 921 participants. The update also adds new interventions including parent training (two studies), mindfulness-based positive behaviour support (MBPBS) (two studies), reciprocal imitation training (RIT; one study) and dialectical behavioural therapy (DBT; one study). It also adds two new studies on PBS. Most studies were based in the community (14 studies), and one was in an inpatient forensic service. Eleven studies involved adults only. The remaining studies involved children (one study), children and adolescents (one study), adolescents (one study), and adolescents and adults (one study). One study included boys with fragile X syndrome. Six studies were conducted in the UK, seven in the USA, one in Canada and one in Germany. Only five studies described sources of funding. Four studies compared anger management based on cognitive behaviour therapy to a wait-list or no treatment control group (n = 263); two studies compared PBS with treatment as usual (TAU) (n = 308); two studies compared carer training on mindfulness and PBS with PBS only (n = 128); two studies involving parent training on behavioural approaches compared to wait-list control or TAU (n = 99); one study of mindfulness to a wait-list control (n = 34); one study of adapted dialectal behavioural therapy compared to wait-list control (n = 21); one study of RIT compared to an active control (n = 20) and one study of modified relaxation compared to an active control group (n = 12). There was moderate-certainty evidence that anger management may improve severity of aggressive behaviour post-treatment (MD -3.50, 95% CI -6.21 to -0.79; P = 0.01; 1 study, 158 participants); very low-certainty evidence that it might improve self-reported ability to control anger (MD -8.38, 95% CI -14.05 to -2.71; P = 0.004, I2 = 2%; 3 studies, 212 participants), adaptive functioning (MD -21.73, 95% CI -36.44 to -7.02; P = 0.004; 1 study, 28 participants) and psychiatric symptoms (MD -0.48, 95% CI -0.79 to -0.17; P = 0.002; 1 study, 28 participants) post-treatment; and very low-certainty evidence that it does not improve quality of life post-treatment (MD -5.60, 95% CI -18.11 to 6.91; P = 0.38; 1 study, 129 participants) or reduce service utilisation and costs at 10 months (MD 102.99 British pounds, 95% CI -117.16 to 323.14; P = 0.36; 1 study, 133 participants). There was moderate-certainty evidence that PBS may reduce aggressive behaviour post-treatment (MD -7.78, 95% CI -15.23 to -0.32; P = 0.04, I2 = 0%; 2 studies, 275 participants) and low-certainty evidence that it probably does not reduce aggressive behaviour at 12 months (MD -5.20, 95% CI -13.27 to 2.87; P = 0.21; 1 study, 225 participants). There was low-certainty evidence that PBS does not improve mental state post-treatment (OR 1.44, 95% CI 0.83 to 2.49; P = 1.21; 1 study, 214 participants) and very low-certainty evidence that it might not reduce service utilisation at 12 months (MD -448.00 British pounds, 95% CI -1660.83 to 764.83; P = 0.47; 1 study, 225 participants). There was very low-certainty evidence that mindfulness may reduce incidents of physical aggression (MD -2.80, 95% CI -4.37 to -1.23; P < 0.001; 1 study; 34 participants) and low-certainty evidence that MBPBS may reduce incidents of aggression post-treatment (MD -10.27, 95% CI -14.86 to -5.67; P < 0.001, I2 = 87%; 2 studies, 128 participants). Reasons for downgrading the certainty of evidence were risk of bias (particularly selection and performance bias); imprecision (results from single, often small studies, wide CIs, and CIs crossing the null effect); and inconsistency (statistical heterogeneity).

AUTHORS' CONCLUSIONS

There is moderate-certainty evidence that cognitive-behavioural approaches such as anger management and PBS may reduce outwardly directed aggressive behaviour in the short term but there is less certainty about the evidence in the medium and long term, particularly in relation to other outcomes such as quality of life. There is some evidence to suggest that combining more than one intervention may have cumulative benefits. Most studies were small and there is a need for larger, robust randomised controlled trials, particularly for interventions where the certainty of evidence is very low. More trials are needed that focus on children and whether psychological interventions lead to reductions in the use of psychotropic medications.

Use of psychotropic medications in adults with intellectual disability: A systematic review and meta-analysis

OBJECTIVE

This study presents the proportion of adults with intellectual disability using psychotropic medications including antipsychotics, antidepressants, anxiolytics, hypnotics and sedatives, and psychostimulants.

METHODS

A search was performed in PubMed, Embase, PsycINFO, Web of Science, and Scopus up to 31 December 2021. Articles were included if they reported the proportion of adults with intellectual disability using psychotropic medications. Frequency of use was estimated using a random effects meta-analysis. Meta-regression analysis was used to assess the association between study-level characteristics and variability in estimates, when heterogeneity was considerable.

RESULTS

Twenty-four articles were included in pooled analysis. The pooled prevalence of psychotropic medications was 41% (95% confidence interval: 35-46%). Pooled prevalences of subclasses were as follows: antipsychotics 31% (27-35%), antidepressants 14% (9-19%), anxiolytics 9% (4-15%), hypnotics/sedatives 5% (2-8%), and psychostimulants 1% (1-2%). Heterogeneity was considerable between studies, except for psychostimulants. There was no significant association between assessed characteristics and variability in prevalence estimates.

CONCLUSION

Two-fifths of adults with intellectual disability were prescribed psychotropic medications. Antipsychotics and antidepressants were used by one-third and one-seventh of adults, respectively. There was considerable variability between studies, and further investigation is required to determine the source of variability. More studies are needed to better characterise prescribed psychotropic medications, including effectiveness and adverse effects, to ensure appropriate use of these drugs.

Nonpharmacological Compensation of Aggressive Behavior of Individuals with Moderate Intellectual Disability and Behavioral Disorders-A Case Study

The article discusses issues associated with the manifestations of aggressive behavior in an individual diagnosed with moderate intellectual disability and behavioral disorders (according to ICD-10; F7; F711—moderate intellectual disability, significant impairment of behavior requiring attention or treatment). In the research survey, we focused on a client corresponding with relevant features. The research was carried out at the beginning of hospitalization, ongoing hospitalization, and the end of hospitalization, followed by a recommendation to limit the legal capacity of the client and his placement in a residential care home. The case study points out individual approaches to special education and psychology and outlines the key steps in the cooperation of selected helping professions suggesting conclusions and recommendations for practice regarding these selected issues. Upon the termination of our investigation, there was a rapid deterioration of the client being admitted to the intensive care unit with a follow-up treatment in a long-term intensive care unit.

The use of transcranial direct current stimulation (tDCS) to reduce impulsivity and aggression in adults with mild intellectual developmental disabilities: the tDCS-RIADD randomised controlled trial protocol

Background

Challenging behaviours, in particular aggressive behaviours, are prevalent among people with intellectual developmental disabilities. Predictors of challenging behaviours are numerous, including past history of aggression, poor coping skills and impulsivity. Factors like motor or rapid-response impulsivity (RRI) have neurobiological underpinnings that may be amenable to change via neuromodulation using non-invasive brain stimulation techniques like transcranial direct current stimulation (tDCS).

Methods

This study aims to determine the efficacy of anodal tDCS in reducing RRI and incidents of aggression in people with intellectual developmental disabilities (IDD) in residential or hospital settings. Using a single blind, randomised, sham-controlled trial design, adults with IDD, with a history of impulsivity leading to aggression, will be randomised to receive either repetitive anodal or sham tDCS applied to the left dorsolateral prefrontal cortex. Outcome measures assessing impulsivity and aggression will be collected for up to 1 month following the last tDCS session.

Discussion

The results of this study may pave the way for developing targeted interventions for impulsivity and aggressive behaviours in people with IDD.

Clinical Safety and Treatment of Severe Aggression: Behavioral-Pharmacological Intervention Evaluation in a Young Adult With Autism Spectrum Disorder

This case study concerned clinical safety and behavioral-pharmacological intervention with an 18-year-old man who had autism spectrum disorder and high-frequency aggression toward care providers at a specialized school. A multicomponent behavior support plan included antecedent, differential reinforcement, environmental modification, and physical management procedures subsequently combined with psychotropic medication (aripiprazole). Clinical safety components emphasized comprehensive care provider training, continuous supervision, function-based treatment, and prevention-focused strategies. The behavioral-pharmacological intervention eliminated implementation of aggression-contingent physical restraint and was associated with increased transition compliance during the school day. Throughout the 7.5 months duration of the study, there were no injuries to the participant or other students and a single injury was sustained by one care provider. Intervention effects were long-standing, and care providers rated their training, implementation fidelity, and therapeutic outcome favorably.

Prevalence and correlates of aggressive behavior in psychiatric inpatient populations

Aggressive behavior in patients with psychiatric disorders is attracting increasing research interest. One reason for this is that psychiatric patients are generally considered more likely to be aggressive, which raises a related question of whether diagnoses of psychiatric disorders predict the prevalence of aggressive behavior. Predicting aggression in psychiatric wards is crucial, because aggressive behavior not only endangers the safety of both patients and staff, but it also extends the hospitalization times. Predictions of aggressive behavior also need careful attention to ensure effective treatment planning. This literature review explores the relationship between aggressive behavior and psychiatric disorders and syndromes (dementia, psychoactive substance use, acute psychotic disorder, schizophrenia, bipolar affective disorder, major depressive disorder, obsessive-compulsive disorder, personality disorders and intellectual disability). The prevalence of aggressive behavior and its underlying risk factors, such as sex, age, comorbid psychiatric disorders, socioeconomic status, and history of aggressive behavior are discussed as these are the components that mostly contribute to the increased risk of aggressive behavior. Measurement tools commonly used to predict and detect aggressive behavior and to differentiate between different forms of aggressive behavior in both research and clinical practice are also reviewed. Successful aggression prevention programs can be developed based on the current findings of the correlates of aggressive behavior in psychiatric patients.

Psychiatric Presentations and Medication Use in Older Adults With Intellectual and Developmental Disabilities

OBJECTIVE

Adults with intellectual and developmental disabilities (IDD) are living longer, yet research about the medical and psychiatric needs of older adults still lags behind that of younger individuals with IDD. The aim of this study was to assess age-related differences in the mental health presentations of adults with IDD.

METHODS

Fully deidentified data for adults 30 years and older were extracted from the START (Systemic, Therapeutic, Assessment, Resources, and Treatment) Information Reporting System, a deidentified database housed at the Center for START Services. Caregivers and START team documents reported psychiatric diagnoses, service use, recent stressors, and challenging behaviors. t Tests, Mann Whitney U tests, χ² tests, and multinominal logistic regression models were used to compare the two age groups, 30-49 years (n = 1,188) versus 50 years and older (n = 464).

RESULTS

Older adults had more medical conditions, fewer reported psychiatric conditions, and were more likely to be taking more psychiatric medications compared to younger adults, after adjusting for demographic variables, disability level, and number of recent stressors.

CONCLUSION

Although older individuals reported fewer psychiatric diagnoses, they were more likely to take higher numbers of psychiatric medications and have more medical conditions. Clinicians and researchers ought to devote more attention to the healthcare needs of older adults with IDD, a vulnerable group exposed to polypharmacy and at risk of adverse events.

Comparison of Autistic Individuals Who Engage in Self-Injurious Behavior, Aggression, and Both Behaviors

BACKGROUND

Two of the most challenging behaviors exhibited by individuals on the autism spectrum are self-injurious behavior (SIB) and aggression. The aim of this study was to identify co-occurring symptoms, behaviors, and medical comorbidities that may provide insight into understanding and treating these behaviors.

METHOD

A large-scale online survey was used to collect data on symptoms, behaviors, and medically related comorbidities commonly reported in individuals with autism spectrum disorders (ASD). Based on responses from 2327 participants, individuals with ASD were divided into four categories: individuals who engaged in SIB only, individuals who engaged in aggression only, individuals who engaged in both behaviors, and individuals who engaged in neither behavior.

RESULTS

There were several characteristics and comorbidities associated with those who engaged in SIB only and in aggression only, in addition to those who engaged in both behaviors.

CONCLUSION

The findings in this study provide evidence to support at least two underlying causes of these behaviors (insensitivity to pain and reactions to food) as well as implications for treating them. Furthermore, several behaviors often observed during early childhood may be considered early predictors of these challenging behaviors.

Trauma, intellectual and/or developmental disability, and multiple, complex needs: A scoping review of the literature

BACKGROUND

Trauma is a significant underlying factor in the multimorbidity of people with Intellectual and/or Development Disabilities (IDD). This relationship is further complicated by a growing recognition of a subset of multiply stigmatized individuals with an IDD and complex, intersecting health and social needs.

AIM

The aim of this review was to examine what is known about trauma and people with an IDD and complex needs, as defined by Community Living British Columbia's (CLBC) Multiple, Complex Needs (MCN) framework, through a broad review of relevant literature.

METHOD AND PROCEDURES

We conducted a scoping review of the peer-reviewed (9 disability journals; 7 academic databases) and grey (2 grey literature databases) on IDD and trauma through an inclusive approach that used search criteria drawn from the defining features of CLBC's MCN Framework.

OUTCOMES AND RESULTS

Apart from there being a limited amount of research on trauma and IDD, two key findings emerged. Through differing approaches that get at issues of trauma in different ways (i.e., through adverse life events or experiences of abuse), the first finding is that the research related to trauma and IDD is not cleanly linked together. The second is the focus on treatment services or interventions and not on what's happening at the organizational or system level.

CONCLUSION AND IMPLICATIONS

There is limited research on trauma and IDD making it even more important to unify the evidence that exists. However, the literature is not integrated across different theoretical and disciplinary perspectives. In addition, the focus of trauma-related research that is occurring is interventions at the individual versus system level. Also needed are studies that explore trauma-informed practice from an organizational or top-down perspective.

Reliability and validity of the Japanese version of the Behavior Problem Inventory-Short Form

BACKGROUND

The Behavior Problems Inventory-Short Form (BPI-S), which assesses behavior problems in individuals with intellectual disabilities (ID), is a shorter version of the BPI-01. This study investigated the reliability and validity of the BPI-S Japanese version (BPI-S-J) for adolescents/adults with ID and behavior problems.

METHODS

The test-retest reliability included participants with ID and behavioral problems who were enrolled in welfare services. For test-retest reliability, 42 caregivers independently responded to the BPI-S-J every two weeks. Inter-rater reliability was independently assessed using the BPI-S-J by two caregivers who were familiar with the 42 participants. The participants of the validity assessment were 227 students from special needs schools or patients with ID admitted to medical institutions. The total frequency total score was compared based on the degree of ID. To examine the criterion-related validity, we analyzed the total frequency score, the total score of the Criteria for Determining Severe Problem Behavior (CDSPB) and the total score of the Aberrant Behavior Checklist-Japanese version (ABC-J).

RESULTS

The BPI-S-J of test-retest reliability was satisfactory (intra-class correlation; ICC) = 0.954), and the total score significantly (ICC = 0.721) represented good inter-rater reliability. For the validity, the BPI-S-J score of participants who had severe and profound ID was significantly higher than those who had mild and moderate ID. Significant correlations were observed between the BPI-S-J score and CDSPB score (r = 0.499), and the ABC-J score (r = 0.699), indicating adequate criterion-related validity.

CONCLUSION

This study showed the utility of the BPI-S-J to assess behavior problems in the Japanese ID population.

Clinical and cost evaluation of intensive support team (IST) models for adults with intellectual disabilities who display challenging behaviour: a comparative cohort study protocol

INTRODUCTION

Approximately 17% of adults with intellectual disabilities (ID) living in the community display behaviours that challenge. Intensive support teams (ISTs) have been recommended to provide high-quality responsive care aimed at avoiding unnecessary admissions and reducing lengthy inpatient stays in England. We have identified two models of ISTs (model 1: enhanced provision and model 2: independent provision). This study aims to investigate the clinical and cost-effectiveness of the two models of ISTs.

METHODS AND ANALYSIS

A cohort of 226 adults with ID displaying behaviour that challenges who receive support from ISTs from each model will be recruited and assessed at baseline and 9 months later to compare the clinical and cost-effectiveness between models. The primary outcome is reduction in challenging behaviour measured by the Aberrant Behaviour Checklist-Community (ABC-C). The mean difference in change in ABC score between the two IST models will be estimated from a multilevel linear regression model. Secondary outcomes include mental health status, clinical risk, quality of life, health-related quality of life, level of functioning and service use. We will undertake a cost-effectiveness analysis taking both a health and social care and wider societal perspective. Semistructured interviews will be conducted with multiple stakeholders (ie, service users, paid/family carers, IST managers/staff) to investigate the experience of IST care as well as an online survey of referrers to capture their contact with the teams.

ETHICS AND DISSEMINATION

The study was approved by the London-Bromley Research Ethics Committee (REC reference: 18/LO/0890). Informed consent will be obtained from the person with ID, or a family/nominated consultee for those lacking capacity and from his/her caregivers. The findings of the study will be disseminated to academic audiences, professionals, experts by experience and arm's-length bodies and policymakers via publications, seminars and digital platforms.

Evaluation of a Brief Family-Centered Service Provision Model for Treating Children's Severe Behavior: A Retrospective Consecutive Case Series Analysis

This article serves as an initial program evaluation of a service provision model for providing applied behavior analysis services to families with severe behavior needs. A retrospective consecutive case series design was used to evaluate the effectiveness, feasibility, and cost of the model. We analyzed records for all families served through the model from summer 2017 to fall 2018. A total of 55 families received services, with 87% of children having autism and 63% having an intellectual disability. Within-participant single-case experimental designs were used to evaluate the clinic's assessment procedures, and caregiver interviews were used to evaluate the feasibility and effectiveness of developed and implemented treatments. Conclusive assessment results were obtained for approximately 69% of children. For families that received treatment, 92% reported improved child behavior. Intent-to-treat analyses that included families that withdrew from services prior to receiving treatment indicated that 61% of families experienced improved child behavior. Assessment and treatment outcomes for families that attended all appointments are commensurate with those of other similar clinics reported in the literature; however, the percentage of families that withdrew from services is substantially higher. For families adhering to the clinic's services, children's challenging behavior may be effectively assessed and treated through brief outpatient contacts utilizing services based on applied behavior analysis.

Family Members of Adults with Intellectual Disability Living in Residential Settings: Roles and Collaboration with Professionals. A Review of the Literature

The aim of this article is to review the literature concerning the role of family members of adults with an intellectual disability living in diverse residential settings and their collaboration with residential staff. Whenever the scarce literature on the subject allowed, the focus was laid on family members of persons with additional challenging behavior. Electronic databases, reference screening, and hand search of selected journals was employed to collate literature using key terms such as family members, intellectual disability, and residential setting. By extracting relevant data of the eighteen articles that fulfilled all inclusion criteria, the following 3 main themes with each subthemes were identified inductively: roles of family members after the transition, the effects of the transition on family members, and the collaboration between the family members and professional care staff. This review presents the different roles family members partake and highlights the importance of regular open two-sided communication for collaboration with professional staff to be successful. Practical implementations are discussed and the need for further research in the field is indicated.

Sensory Processing and Aggressive Behavior in Adults with Autism Spectrum Disorder

Autism spectrum disorder (ASD) may be accompanied by aggressive behavior and is associated with sensory processing difficulties. The present study aims to investigate the direct association between sensory processing and aggressive behavior in adults with ASD. A total of 101 Dutch adult participants with ASD, treated in outpatient or inpatient facilities, completed the Adolescent/Adult Sensory Profile (AASP), the Reactive-Proactive Aggression Questionnaire (RPQ), and the Aggression Questionnaire—Short Form (AQ-SF). Results revealed that sensory processing difficulties are associated with more aggressive behavior (f2=0.25), more proactive (f2=0.19) and reactive aggression (f2=0.27), more physical (f2=0.08) and verbal aggression (f2=0.13), and more anger (f2=0.20) and hostility (f2=0.12). Evidence was found for an interaction of the neurological threshold and behavioral response on total aggression and hostility. Participants with higher scores in comparison to the norm group in sensory sensitivity had the highest risk of aggressive behavior. In conclusion, clinical practice may benefit from applying detailed diagnostics on sensory processing difficulties when treating aggressive behavior in adults with ASD.

Recognition and Treatment of Tardive Dyskinesia in Individuals with Intellectual Disability

Individuals with intellectual disability (ID) commonly suffer from comorbid psychiatric and behavioral disorders that are frequently treated by antipsychotic medications. All individuals exposed to first- and second/third- generation antipsychotics are at risk for developing tardive dyskinesia (TD), characterized by abnormal, involuntary movements of the mouth/tongue/jaw, trunk, and extremities. TD can be highly disruptive for affected individuals and their caregivers, causing embarrassment, isolation, behavioral disturbances, and reduced functioning and quality of life. Information on TD incidence in individuals with ID is limited, but 2 small US studies reported TD prevalence rates of 42-45% in inpatients with ID. The safety and efficacy of vesicular monoamine transporter type 2 (VMAT2) inhibitors approved for treatment of TD in adults have been demonstrated in multiple clinical trials, but they excluded individuals with ID. Clinical characteristics and treatment outcomes of 5 adults (aged 28-63 years) with mild-to-severe ID and TD are presented, illustrating TD symptoms before/after treatment. All individuals had multiple comorbid psychiatric, behavioral, and other medical conditions, history of antipsychotic exposure, and abnormal movements affecting the tongue/mouth/jaw (n = 5), upper extremities (n = 5), lower extremities (n = 3), and trunk (n = 2), resulting in diminished ability to speak (n = 2), ambulate (n = 3), and perform activities of daily living (n = 3). Treatment with valbenazine resulted in meaningful improvements in TD symptoms and improved daily functioning, demeanor, and social/caregiver interactions. Given the high likelihood of antipsychotic exposure in the ID population, it is appropriate to screen for TD at every clinical visit through careful monitoring for abnormal movements and questioning the individual/caregiver regarding abnormal movements or TD-related functional impairments (i.e., speaking, swallowing, eating, ambulating, and social functioning). In this study, 5 individuals with ID and TD received once-daily valbenazine and experienced marked improvement in TD symptoms and daily functioning, resulting in increased quality of life for affected individuals and caregivers.

The Prevalence of Self-injurious Behaviour in Autism: A Meta-analytic Study

Self-injurious behaviour is purportedly common in autism, but prevalence rates have not yet been synthesised meta-analytically. In the present study, data from 14,379 participants in thirty-seven papers were analysed to generate a pooled prevalence estimate of self-injury in autism of 42% (confidence intervals 0.38-0.47). Hand-hitting topography was the most common form of self-injury (23%), self-cutting topography the least common (3%). Sub-group analyses revealed no association between study quality, participant intellectual disability or age and overall prevalence rate of self-injury. However, females obtained higher prevalence rates than males (p = .013) and hair pulling and self-scratching were associated with intellectual disability (p = .008 and p = .002, respectively). The results confirm very high rates of self-injury in autism and highlight within group risk-markers.

Psychotropic medications use and side effects of individuals with intellectual and developmental disabilities

BACKGROUND

Many people with intellectual and developmental disabilities (IDD) are treated with psychotropic medications, and polypharmacy is common. Although few studies address psychotropic side effects in the population, people with IDD have been found more likely to experience side effects than others who do not have IDD. Because many individuals with IDD may not report side effects reliably, there is risk that side effects may be missed.

METHODS

Psychotropic use and side effects of 71 adults with IDD admitted for a 30-day crisis stay to a Systemic, Therapeutic, Assessment, Resources, and Treatment (START) Resource Center were reviewed. START is a specialised behavioural health outreach, training and crisis programme for individuals with IDD. During crisis stays, centre nurses administer the Matson Evaluation of Drug Side Effects screen, a psychometrically established psychotropic medication side effects screen developed for use with people with IDD. Data reviewed were de-identified data used to inform day-to-day practices and assess outcomes for individuals START served.

RESULTS

The average age was 28 years, and 56% of the sample was male. All individuals were taking at least one psychotropic, while 79% were taking three or more. The average number of psychotropics used was 3.94. Antipsychotics were the most commonly prescribed medications taken by 85% of the sample; 49% of whom were not reported to have psychosis. Although the overall number of psychotropics did not correlate with Matson Evaluation of Drug Side Effects scores, the average scale scores for all participants was high in contrast to prior studies of people with IDD not taking psychotropics, with central nervous system side effects being the most commonly reported.

CONCLUSION

In the present study, data for individuals experiencing a crisis were reviewed and indicated high rates of psychotropic polypharmacy and side effects rates higher than previously reported for people with IDD not taking psychotropics. Prospective study in larger samples is needed to determine if missed or under-appreciated psychotropic side effects may play a role in behavioural health challenges of some people with IDD.

Behavioural, psychiatric and psychosocial factors associated with aggressive behaviour in adults with intellectual disabilities: A systematic review and narrative analysis

Background

Aggressive behaviour is prevalent in people with intellectual disabilities. To understand the aetiology, it is important to recognize factors associated with the behaviour.

Method

A systematic review was conducted and included studies published between January 2002 and April 2017 on the association of behavioural, psychiatric and psychosocial factors with aggressive behaviour in adults with intellectual disabilities.

Results

Thirty‐eight studies were included that presented associations with 11 behavioural, psychiatric and psychosocial factors. Conflicting evidence was found on the association of these factors with aggressive behaviour.

Conclusions

The aetiology of aggressive behaviour is specific for a certain person in a certain context and may be multifactorial. Additional research is required to identify contributing factors, to understand causal relationships and to increase knowledge on possible interaction effects of different factors.

Association between epilepsy and challenging behaviour in adults with intellectual disabilities: systematic review and meta-analysis

BACKGROUND

Previous systematic reviews showed no significant association between epilepsy and challenging behaviours in adults with intellectual disabilities.

AIMS

To identify whether there is an association between epilepsy and challenging behaviour in adults with intellectual disabilities by carrying out a systematic review of published data. PROSPERO registration number: CRD42020178092.

METHOD

We searched five databases and hand-searched six journals. Two authors independently screened titles, abstracts and full articles using a standardised eligibility checklist. Several meta-analyses were carried out.

RESULTS

The narrative analysis of data from 34 included articles (14 168 adults with intellectual disabilities, 4781 of whom also had epilepsy) showed no significant association between epilepsy and challenging behaviour. Meta-analysis was possible on data from 16 controlled studies. This showed no significant intergroup difference but after sensitivity analysis meta-analysis of 10 studies showed a significantly higher rate of overall challenging behaviour in the epilepsy group (effect size: 0.16) compared with the non-epilepsy group. Aggression and self-injurious behaviour both showed a statistically significant higher rate in the epilepsy group, with very small effect sizes (0.16 and 0.28 respectively). No significant intergroup difference was observed in the rate of stereotypy.

CONCLUSIONS

The findings are contradictory and must be interpreted with caution because of the difficulty in pooling data from varied studies, which is likely to introduce confounding. Where significant differences were found, effect sizes are small and may not be clinically significant, and there are major methodological flaws in the included studies, which should be addressed in future large-scale properly controlled studies.

Factors affecting the relationship between adaptive behavior and challenging behaviors in individuals with intellectual disability and co-occurring disorders

Previous studies have reported an inverse relationship between adaptive behavior and challenging behaviors in individuals with ID. However, it is unclear which characteristics might influence this relationship in individuals with ID and co-occurring conditions. We found a positive correlation between adaptive behavior (Vineland-II) and challenging behaviors (Nisonger Child Behavior Rating Form) in a study of 105 individuals who presented with mostly severe to profound ID and comorbid physical and mental health conditions. These results might be the consequence of the individual participant characteristics. Therefore, participants were separated out into two groups representing the top (n = 24) and bottom quartiles (n = 28) for presence of challenging behaviors. The participants with the highest levels of challenging behaviors had higher levels of adaptive behavior, higher frequency of intermittent explosive/conduct disorder, but lower frequency of epilepsy and cerebral palsy. All participants with the highest levels of challenging behaviors lived in an institutional setting; whereas, those with the lowest level of challenging behaviors lived in either an institutional setting or with their family. In participants with severe/profound ID and multiple co-occurring disorders, a minimum level of adaptive behavior seems to be necessary for the expression of challenging behaviors.

Non-pharmacological interventions for challenging behaviours of adults with intellectual disabilities: A meta-analysis

BACKGROUND

Non-pharmacological interventions are recommended for the treatment of challenging behaviours in individuals with intellectual disabilities by clinical guidelines. However, evidence for their effectiveness is ambiguous. The aim of the current meta-analysis is to update the existing evidence, to investigate long-term outcome, and to examine whether intervention type, delivery mode, and study design were associated with differences in effectiveness.

METHOD

An electronic search was conducted using the databases Medline, Eric, PsychINFO and Cinahl. Studies with experimental or quasi-experimental designs were included. We performed an overall random-effect meta-analysis and subgroup analyses.

RESULTS

We found a significant moderate overall effect of non-pharmacological interventions on challenging behaviours (d = 0.573, 95% CI [0.352-0.795]), and this effect appears to be longlasting. Interventions combining mindfulness and behavioural techniques showed to be more effective than other interventions. However, this result should be interpreted with care due to possible overestimation of the subgroup analysis. No differences in effectiveness were found across assessment times, delivery modes or study designs.

CONCLUSIONS

Non-pharmacological interventions appear to be moderately effective on the short and long term in reducing challenging behaviours in adults with intellectual disabilities.

Adult neurodevelopmental services in Singapore: A sociodemographic and clinical profile at a tertiary psychiatric hospital

INTRODUCTION

The Adult Neurodevelopmental Service in Singapore is the first service of its kind in South-East Asia for adults with intellectual disability (ID) and/or autism spectrum disorder (ASD). However, few studies have documented and compared the sociodemographic characteristics and clinical needs of this subpopulation group.

METHODS

Initial assessments conducted from 1 January 2015 to 31 December 2016 were retrospectively reviewed for this descriptive study.

RESULTS

A total of 272 patients were included in the study (mean age 28.3 ± 11.5; 200 males, 72 females). Adults with ID comprised the largest percentage (52.9%), followed by those with ASD (30.2%), and then those with co-occurring ASD and ID (16.9%). The ASD subgroup had the highest proportion of individuals with employment, postsecondary school education, functional capabilities, and a psychiatric disorder. In comparison, adults with only ID and adults with co-occurring ASD and ID shared similar lower levels of education and employment, and had a higher proportion of individuals with epilepsy and aggressive behavior.

DISCUSSION

In this study, adults with ASD had a unique social profile with different clinical needs compared to adults with only ID or to adults with co-occurring ASD and ID. Adults with only ID and those with co-occurring ASD shared many of the same social characteristics and high clinical needs. The analysis of these profiles will be useful in developing services that better meet the needs of this complex group.

Residents' and resident representatives' perspectives on the influence of the organisational environment on challenging behaviour

BACKGROUND

This study explored the perspectives of residents of residential disability service organisations and resident representatives on the influence of the organisational environment on challenging behaviour in people with intellectual disabilities (ID).

METHOD

Sixteen residents and representatives from four specialised Dutch disability service organisations were interviewed. Data were analysed using a grounded theory approach, with a sensitising frame based on Bronfenbrenner's ecological theory.

RESULTS

Some organisational factors (e.g. staff turnover, insufficient finances) can have negative effects on interactions among residents and staff and family members, resulting in more challenging behaviour, but other organisational factors (e.g. shared vision, values and expectations, competent staff) can positively influence staffs' attitudes and actions, which in turn helps to manage challenging behaviour in people with ID.

CONCLUSIONS

Residents' and representatives' perspectives provide a better understanding of the positive and negative influences of the organisational environment on challenging behaviour in people with ID.

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.

The Persistence of Self-injurious and Aggressive Behavior in Males with Fragile X Syndrome Over 8 Years: A Longitudinal Study of Prevalence and Predictive Risk Markers

Self-injurious and aggressive behaviors are common in fragile X syndrome (FXS). However, little is known about the persistence of these behaviors and associated risk markers. We established the prevalence and persistence of self-injurious and aggressive behaviors over eight years in males with FXS, and associations with risk markers. Results showed 77% and 69% persistence rates for self-injurious and aggressive behavior, respectively. Baseline levels of repetitive behavior predicted persistent self-injurious behavior. Chronological age, impulsivity and overactivity were associated with persistent aggressive behavior but only impulsivity predicted persistence. This is the first study to document the persistence of self-injurious and aggressive behavior in FXS over the medium to long term and to identify behavioral risk markers that might facilitate targeted early intervention.

Behavioral Treatment of Self-Injury: 2001 to 2016

Individuals diagnosed with intellectual and developmental disabilities (IDD) frequently exhibit self-injurious behavior (SIB). Previous research has examined the published literature on behavioral treatments of SIB from 1964-2000. Results suggested that these treatments were highly efficacious at decreasing SIB, particularly when based on the results of a functional assessment. The purpose of this review is to update, replicate, and extend the previous research. The current findings indicate an increase in studies reporting automatically maintained SIB as well as less efficacious treatments overall. Discussion of our conclusions and methods of SIB assessment and treatment are discussed, both as they relate to the previous review and for future directions.

Assessments and Interventions to Address Challenging Behavior in Individuals with Intellectual Disability and Autism Spectrum Disorder in Japan: A Consolidated Review

Intellectual disability and autism spectrum disorder are neurodevelopmental disorders that emerge during the developmental period. A significant barrier that impedes the social adaptation of individuals with these disorders is the exhibition of problem behaviors, such as self-injurious, stereotyped, and aggressive/destructive behaviors. In recent years, these problem behaviors have been collectively referred to as "challenging behavior," in accordance with the contention that they result from an interaction between the individual and his or her social environment. Evidence-based psychosocial interventions that adopt the functional approach to treating challenging behavior are increasing. However, in order to effectively implement such interventions in educational settings and welfare facilities, it is essential to develop staff training programs and usable psychometric assessments. Accordingly, a brief overview of research studies on challenging behavior that have been conducted in Japan, as well as the various support systems that are available to individuals who exhibit challenging behavior, are presented in this article. The discussion makes it apparent that, in order to improve treatment systems in Japan that are aimed at addressing challenging behavior, it is necessary to establish not only better staff training programs, but also reliable and valid assessments measuring challenging behavior that can be readily used by teachers and parents. On the basis of this discussion, it is proposed that technological advancements must be applied to psychosocial approaches in the study of problem behaviors, in order to develop assessment system using software applications and automatic measurement system of target behaviors using sensing technology.

ADHD in children and youth: Part 3-Assessment and treatment with comorbid ASD, ID, or prematurity

Attention-deficit hyperactivity disorder (ADHD) is a chronic neurodevelopmental disorder. Three position statements have been developed by the Canadian Paediatric Society, following systematic literature reviews. Statement objectives are to: 1) Summarize the current clinical evidence regarding ADHD,2) Establish a standard for ADHD care, and3) Assist Canadian clinicians in making well-informed, evidence-based decisions to enhance care of children and youth with this condition. Specific topics reviewed in Part 3, which focuses on associated autism spectrum disorder, intellectual disability, and prematurity, include the challenges of diagnostic assessment, common presentations, the role of genetics, and treatment, including the benefits of physical activity. Recommendations are based on current guidelines, evidence from the literature, and expert consensus.

Persistence of self-injury, aggression and property destruction in children and adults with tuberous sclerosis complex

BACKGROUND

Individuals with tuberous sclerosis complex (TSC) are at increased risk of developing self-injurious behaviour. The persistence of this deleterious behaviour over years is reported in aetiologically heterogeneous samples to be between 60% and 80% but is unknown for TSC.

METHOD

In this study, we determined the 3-year persistence of self-injury in a sample (n = 52) of children (with and without ID) and adults (with ID) with TSC and examined characteristics associated with persistence.

RESULTS

Findings for self-injury were contrasted to those for aggression and property destruction to examine the specificity of results to this behaviour. Self-injury was persistent in 84.6% of those with TSC who showed this behaviour, in contrast to 66.7% both for aggression and destruction. Persistent self-injury was associated with poor self-help skills, greater overactivity/impulsivity and more behavioural indicators of pain. These latter two characteristics were also associated with persistent aggression. No characteristics were associated with persistence of property destruction.

CONCLUSION

These findings suggest that self-injurious behaviours in individuals with TSC, together with aggressive and destructive behaviours, are highly persistent and would benefit from targeted intervention. Poor adaptive skills, overactivity/impulsivity and painful health conditions may differentiate those at most risk for persistent self-injury or aggression.

Risk factors for challenging behaviour and psychopathology in adults with Down syndrome

BACKGROUND

This study explored the role of demographic, psychosocial, stress and life event-related risk factors for psychopathology and challenging behaviour in a clinical sample of adults with Down syndrome.

METHOD

A convenience sample of adults with Down syndrome seen through a specialised clinic was assessed through interviews and questionnaires specifically designed for use in people with intellectual disabilities.

RESULTS

Recent negative life events and stressors were significantly correlated with mental and behavioural health, and significantly predicted irritability, lethargy and depressed mood. Social avoidance was predicted by stress related to anticipation and social-environmental stressors, and negatively predicted by verbal ability. Ritual-related stress predicted obsessive-compulsive behaviour. Participants who did not have a job or vocational placement were significantly more depressed than participants who did.

CONCLUSIONS

Adults with Down syndrome should be provided increased supports for coping with negative life events and stressors. Interventions should also emphasise community engagement, such as employment, and access to psychosocial supports that teach coping and self-regulation skills when faced with stressors and negative life events.

Steps to Effective Problem-Solving in group homes

Aggressive/challenging behaviors (A/CB) are a major public health problem for individuals with intellectual disabilities (ID). A leading reason for psychiatric hospitalizations and incarcerations, such behaviors are costly to the health care system, agencies, and families. Social problem-solving (SPS) training programs for individuals with ID have had positive behavioral results, but most were conducted in clinical or forensic settings. None was a community-based preventive intervention, none examined whether the behaviors decreased in residential and work settings, and none addressed cost-effectiveness. In preliminary work, we modified an effective SPS training program (ADAPT: Attitude, Define, Alternatives, Predict, and Try out), using input from individuals with ID and residential staff, as a community-based preventive intervention that we delivered in group homes (STEPS: Steps to Effective Problem-solving). Individuals with ID have high rates of obesity, and our attention-control condition is a nutrition intervention: Food for Life. We describe the protocol for a randomized clinical trial to: (1) test the efficacy of the STEPS intervention for improving SPS skills and reducing A/CB compared to an attention-control nutrition intervention in group homes; (2) assess the mediating effect of residential staff SPS skills, group-home level SPS skills, and group cohesiveness on the improvement of SPS skills and reductions in A/CB; and (3) evaluate the cost-effectiveness of STEPS. We expect to show that STEPS is a preventive strategy to reduce A/CBs among individuals with ID and improve the cost-effectiveness of their care.

Prevalence and associated factors of problem behaviours among older adults with intellectual disabilities in Ireland

A growing number of adults with intellectual disabilities (ID) are reaching old age, however, little is known about epidemiology of problem behaviours (PBs) in this population. The aim was to identify the prevalence and associated factors of PBs among older adults with ID in Ireland. Data was generated from Wave 2 of the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA), a nationally representative sample of adults with ID aged ≥40. Data on PBs was available for 683 (98.3%) of individuals. Over half (53%; n = 362) reported displaying any PB (verbal aggression, physical aggression, destruction, self-injury, or "other" PB). Multivariate analyses indicated PBs were independently associated with moderate or severe/profound ID, living in a community group home or residential centre, experiencing a greater number of life events in the last year, taking psychotropic medication, and reporting a doctor's diagnosis of a psychiatric problem. A considerable number of older adults with ID in Ireland display PBs, which may hinder their opportunities to engage in community based activities and form meaningful social connections. High rates of psychotropic medication and doctor's diagnosis of psychiatric conditions and their associations with PBs were highlighted. Future research should examine mechanisms underlying these linkages.

Challenging behaviours at early adulthood in autism spectrum disorders: topography, risk factors and evolution

BACKGROUND

Challenging behaviours are highly prevalent in children and adolescents with autism spectrum disorders (ASD), but little is known about the prevalence and course of these behaviours during adulthood. The aims of this study were to describe the topography of challenging behaviours in a cohort of 106 young adults with ASD and to identify the risk factors for challenging behaviours. Our secondary objective was to study the changes in challenging behaviours from adolescence to early adult years.

METHOD

The present study uses data from the EpiTED prospective follow-up study in France. The presence of challenging behaviours was assessed by the Aberrant Behaviour Checklist (ABC) completed by parent informants. Several dimensions of behaviour were studied: irritability, stereotypy, lethargy, hyperactivity and self-injury. Clinical variables were collected on ASD symptom severity, cognitive and language levels, adaptive behaviours and comorbid medical disorders.

RESULTS

The presence of challenging behaviours at early adulthood was related to the young adult's cognitive and language level, ASD symptom severity and comorbid gastrointestinal and sleep disorders. The main risk factor for challenging behaviours was ASD symptom severity. The level of language impairment was a significant predictor of self-injury. Gastrointestinal disorders were a significant predictor of stereotypy. The change in behaviour topography from adolescence to early adult years corresponded with decreased parent report of hyperactivity, but no significant decrease in parent reports of irritability, stereotypy, lethargy and self-injurious behaviours.

CONCLUSIONS

The challenging behaviours in individuals with ASD persist in early adulthood and are related to core symptom severity, levels of cognitive and language impairments and medical comorbidity. The results emphasise the importance of early interventions for children with ASD to target cognitive and language abilities and to alleviate the severity of ASD symptoms. They also underscore the need to enhance opportunities for individuals with ASD to better communicate discomforts and pain in the context of medical illness.

Antipsychotic Use With and Without Comorbid Psychiatric Diagnosis Among Adults with Intellectual and Developmental Disabilities

OBJECTIVE

Antipsychotic use is controversial in the management of adults with intellectual and developmental disabilities (IDD) because of inconclusive evidence for efficacy in the absence of a comorbid psychiatric condition, and substantial concerns about adverse effects. We aimed to characterize antipsychotic use among Ontario adults with IDD and compare profiles of those with and without a documented psychiatric diagnosis.

METHOD

This population-based study included 51,881 adults with IDD under 65 y as of April 2010 receiving provincial drug benefits in Ontario who were followed until March 2016 to identify those dispensed at least one antipsychotic medication. Profiles of those with and without a psychiatric diagnosis were compared.

RESULTS

Overall, 39.2% of adults ( n = 20,316) were dispensed an antipsychotic medication, which increased to 56.4% in a subcohort residing in group homes. Almost one-third (28.91%) of people prescribed an antipsychotic medication did not have a documented psychiatric diagnosis. Those without a psychiatric diagnosis differed considerably from those with a diagnosis. In particular, those without a psychiatric diagnosis were older, less likely to have used antidepressants or benzodiazepines in the year before, and less likely to have used ambulatory and acute care.

CONCLUSIONS

Antipsychotic use in IDD is common, and occurs frequently without a psychiatric diagnosis. Attention toward how antipsychotics are prescribed and monitored for people with IDD in Canada is warranted to ensure appropriate prescribing.

The views of carers about support for their family member with an intellectual disability: With a focus on positive behavioural approaches

This qualitative study explored the views of family carers about the support that their adult children with an intellectual disability had received in relation to their behaviour that challenged. There was a particular focus on positive behavioural support (PBS), although some participants spoke more generally in terms of positive approaches. Semi-structured interviews with eight family carers were analysed using inductive thematic analysis. Four key themes were identified. Good support, of which PBS was an example, was seen as both having reduced behaviours that challenged and having a wider positive impact on the quality of life of the individual and their families. Key features highlighted were: technical knowledge and skill; a strong value base of warmth, acceptance and respect; a collaborative, consistent approach; open communication; and the extension of support to the family carer when needed. It was recognised that there is a need for broad systemic change and for the application of a workforce development model that takes account of the needs of staff, carers and those working in wider systems that have contact with people with an intellectual disability.
