Behaviours that challenge in adults with intellectual disability: overview of assessment and management

Less antipsychotics, more Quality of Life tapering strategies for adults with intellectual disabilities and challenging behaviour

BACKGROUND

The long-term off-label use of antipsychotics to manage challenging behaviour in adults with intellectual disabilities is common practice. However, there is limited evidence supporting its effectiveness and safety. Additionally, individuals who use off-label antipsychotics are at risk of experiencing side effects that may negatively impact their Quality of Life.

AIMS

This study investigates the impact of tapering off-label antipsychotics on Quality of Life, challenging behaviour, general functioning, and side effects in adults with intellectual disabilities.

MATERIALS AND METHODS

Twenty-five adults with intellectual disabilities and challenging behaviour were monitored over a 40-week period during which off-label antipsychotic medications were gradually tapered. The tapering process was guided by a multidisciplinary team. The primary outcome was Quality of Life, measured using the Anamnestic Comparative Self-Assessment (ACSA), supplemented by a self-designed instrument tailored to the individual. Secondary outcomes included challenging behaviour, general functioning, and side effects, assessed using the Aberrant Behaviour Checklist (ABC), World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), Section 3B of the Supports Intensity Scale (SIS), and Matson's Evaluation of Drug Side Effects (MEDS).

RESULTS

At the end of the study (40 weeks), 22 participants were taking lower dosages of antipsychotic medication, with two participants tapering off the antipsychotic drugs entirely. On average, participants reduced their medication dosage by 39.7 %. Following tapering, improvements were observed in Quality of Life and overall functioning, alongside reductions in challenging behaviour and side effects.

CONCLUSION

The tapering of off-label antipsychotics in adults with intellectual disabilities resulted in a positive impact on Quality of Life. These findings suggest that Quality of Life could serve as a useful outcome measure to support the consideration of more limited off-label use of antipsychotics.

Mental and Behavioral Health, and Crisis Services for People with Intellectual and Developmental Disabilities in Medicaid Home- and Community-Based Services

People with intellectual and developmental disabilities (IDD) often have higher rates of comorbid mental health conditions compared to the general population. Yet, many people with IDD also have unmet needs for mental and behavioral health services. The aim of this study was to examine how states provided mental and behavior health, and crisis services to people with IDD in their Home- and Community-Based Services (HCBS) programs, the largest funding mechanism for Long-Term Services and Supports (LTSS) for people with IDD in the United States. We analyzed fiscal year (2021) Medicaid HCBS waivers for people with IDD from across the United States to examine if and how they provided mental and behavior health, and crisis services. States projected spending $968.9 million for mental and behavior health, and crisis services for 190,299 people with IDD. Applied behavior analysis services were provided at greater rates than positive behavior supports and other forms of behavior interventions. While most states provided mental and behavior health, and crisis services in their waivers, there were vast inconsistencies in how they did so, across states, waivers, and services. HCBS are a crucial safety net to ensure people with IDD, especially those who also have mental health disabilities, can live and thrive in their communities.

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.

A Forest Bathing Intervention in Adults with Intellectual Disabilities: A Feasibility Study Protocol

Forest bathing practices benefit individuals' physical and mental health. A growing number of published studies provide evidence of such effects in diverse populations and contexts. However, no literature has been found that evaluates the effects of forest bathing on people with intellectual disabilities. In this paper, we present a quasi-experimental pre-post protocol for assessing the preliminary efficacy and feasibility of a forest bathing intervention in a group of adults with intellectual disability. An 11-weekly session program will be applied in the forests of the Ollo Valley, Navarre (Spain). The preliminary efficacy outcomes will be blood pressure, psycho-physiological coherence parameters and quality of life. The feasibility of the intervention will be assessed through data on barriers and facilitators of the implementation process and indicators of environmental comfort (physiological equivalent temperature and thermic perception). This study offers an opportunity for people with intellectual disabilities to benefit from a forest bathing intervention and explore its effects not only on their quality of life, but also on the improvement in their physiological and psychological state. This feasibility study is an essential step to explore crucial aspects for a future full-scale trial.
