Staff training in positive behaviour support for behaviour that challenges in people with intellectual disability: cost-utility analysis of a cluster randomised controlled trial

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

Up to a fifth of people with intellectual disabilities display challenging behaviour that has a significant impact on their health and quality of life. Psychotropic medication does not appear to confer any clinical benefits beyond risk reduction in acute situations. However, very few non-pharmacological treatments have clear evidence of clinical and cost-effectiveness and there is therefore often a dearth of advice as to which components or interventions would be helpful. To our knowledge no single model has been developed to provide a clear path from understanding the behaviour to the implementation of a therapeutic approach for such a complex clinical problem. In this article we describe a stepped-care model that needs to be further operationalised in the assessment and management of behaviours that challenge in adults with intellectual disabilities.

The Effects of Integrated Step Training into the Physical Education Curriculum of Children with Intellectual Disabilities

(1) Background: This study investigated the changes in step frequency, walking ability, and standing posture of students with intellectual disabilities by integrating step training into the students' physical education curriculum; (2) Methods: The centroid formula was used to estimate the geometric center of the students' bodies in video footage of each participant. Each participant's stepping frequency per minute was recorded. After training, the teachers involved were interviewed regarding the participants' everyday activities in school. Each step training session was recorded by two video cameras. Each step training session was observed and photographed by a senior physical education teacher with special education qualifications; (3) Results: The step training increased the stability of the participants' body axes. The participants' average steps per minute of the participants significantly improved from 24.200 ± 7.554 to 28.700 ± 8.629. Additionally, despite the students exhibiting anxious behavior (e.g., squeezing their hands and grasping at their clothes) at baseline, the frequency of these behaviors decreased significantly from week 4. Overall, the students' daily activities, motivation, interpersonal interaction, self-confidence, and anxiety behaviors improved; (4) Conclusions: After the 8-week step program, the participants with intellectual disabilities improved their step frequency, movement stability, ability to perform daily activities, walking speed, motivation, interpersonal interaction, and self-confidence, and they exhibited a lower level of anxiety-related behaviors.

A manualised weight management programme for adults with mild-moderate intellectual disabilities affected by excess weight: A randomised controlled feasibility trial (Shape Up-LD)

BACKGROUND

The aim was to pilot an adapted manualised weight management programme for persons with mild-moderate intellectual disabilities affected by overweight or obesity ('Shape Up-LD').

METHOD

Adults with intellectual disabilities were enrolled in a 6-month trial (3-month active intervention and 3-month follow-up) and were individually randomised to Shape Up-LD or a usual care control. Feasibility outcomes included recruitment, retention, initial effectiveness and cost.

RESULTS

Fifty people were enrolled. Follow-up rates were 78% at 3 months and 74% at 6 months. At 3 and 6 months, controlling for baseline weight, no difference was observed between groups (3 months: β: -0.34, 95% confidence interval [CI]: -2.38, 1.69, 6 months: β: -0.55, 95%CI -4.34, 3.24).

CONCLUSION

It may be possible to carry out a trial of Shape Up-LD, although barriers to recruitment, carer engagement and questionnaire completion need to be addressed, alongside refinements to the intervention.

Challenges to conducting randomised controlled trials with adults with intellectual disabilities: Experiences of international experts

BACKGROUND

Globally, conducting randomised controlled trials can be a complex endeavour. The complexity increases when including participants with cognitive or intellectual disabilities. A fuller understanding of the barriers and challenges that can be expected in such trials may help researchers to make their trials more inclusive for people with disabilities.

METHOD

Semi-structured interviews were conducted with twelve international trial experts.

RESULTS

Eight themes emerged relating to challenges linked to: 1) participant co-morbidities, 2) participant ability levels, 3) ethics and consent, 4) the RCT methodology, 5) gatekeeping, 6) staff turnover, 7) lack of technical understanding and 8) attitudes and perceptions.

CONCLUSION

Conducting trials with cognitively disabled participants can pose unique challenges although many can be overcome with 'reasonable adjustments'. Challenges that are harder to overcome are attitudes and perceptions that people (professional staff, funding bodies, carers or fellow researchers) hold towards the utility of conducting trials with cognitively disabled populations.
