Alertness in individuals with profound intellectual and multiple disabilities: a literature review

Health care management adequacy among French persons with severe profound intellectual and multiple disabilities: a longitudinal study

BACKGROUND

The care organization of persons with profound intellectual and multiple disabilities (PIMD) varies by country according to the health care system. This study used a large sample of French individuals with severe PIMD/polyhandicap to assess: 1) the adequacy of care setting over a 5-year period and 2) health care consumption.

METHODS

The longitudinal study used data from the French EVALuation PoLyHandicap (EVAL-PLH) cohort of persons with severe PIMD/polyhandicap who were receiving managed in specialized care centres and residential facilities. Two assessments were performed: wave 1 (T1) in 2015-2016 and wave 2 (T2) in 2020-2021. The inclusion criteria were as follows: age > 3 years at the time of inclusion; age at onset of cerebral lesion younger than 3 years old; and severe PIMD. The adequacy of the care setting was based on the following: i) objective indicators, i.e., adequacy for age and adequacy for health status severity; ii) subjective indicators, i.e., self-perception of the referring physician about medical care adequacy and educational care adequacy. Health care consumption was assessed based on medical and paramedical care.

RESULTS

Among the 492 persons assessed at the 2 times, 50% of individuals at T1 and 46% of individuals at T2 were in an inadequate care setting based on age and severity. Regarding global subjective inadequacy, the combination of medical adequacy and educational adequacy, 7% of individuals at T1 and 13% of individuals at T2 were in an inadequate care setting. At T2, a majority of individuals were undermonitored by medical care providers (general practitioners, physical medicine rehabilitation physicians, neurologists, orthopaedists, etc.). Important gaps were found between performed and prescribed sessions of various paramedical care (physiotherapy, occupational therapy, psychomotor therapy, etc.).

CONCLUSIONS

This study revealed key elements of inadequate care management for persons with severe PIMD/polyhandicap in France. Based on these important findings, healthcare workers, familial caregivers, patients experts, and health decision-makers should develop appropriate care organizations to optimize the global care management of these individuals.

Modified Ride-on Car Intervention for Children With Profound Intellectual and Multiple Disabilities: A Case Series

PURPOSE

To describe a pilot clinical case series of a modified ride-on car (MROC) intervention on mobility and alertness for young children with profound intellectual and multiple disabilities (PIMD).

METHODS

Four young children with PIMD participated in 4 baseline observations and 5 intervention sessions (A-B design). Data collection occurred via video. Assessment of mobility and alertness duration used structured visual analysis.

RESULTS

Three of the 4 children increased their independent mobility during the intervention sessions. One of the 4 children increased their active alertness during the intervention sessions.

CONCLUSIONS

This pilot study demonstrates the initial feasibility of an MROC intervention in a clinical setting and outcome measures of mobility and alertness for children with PIMD. This provides support that this population should be considered for power mobility in early childhood. Further, this study used a novel, caregiver-implemented prompting protocol to teach children how to use the MROC.

Eye-tracking-based experimental paradigm to assess social-emotional abilities in young individuals with profound intellectual and multiple disabilities

Individuals with Profound Intellectual and Multiple Disabilities (PIMD) experience a combination of severe cognitive and motor impairments frequently associated with additional sensory deficits and numerous medical disorders. The purpose of the present study was to propose an experimental paradigm based on eye-tracking that combines various pre-existing tasks from infancy research as an assessment tool. This would enable the investigation of social-emotional abilities in nine young individuals with PIMD through their visual preferences for different types of stimuli. The first objective was to test the feasibility of this paradigm, by expecting individuals to look more at the tasks’ presentation screen than elsewhere during its implementation. The second objective was to investigate whether PIMD individuals exhibit visual preferences for (a) biological (vs. non-biological) motion, (b) socially salient (vs. non-social) scenes, (c) the facial area of the eyes (vs. the mouth), (d) happy (vs. angry) faces, (e) objects of joint attention (vs. non-looked at ones), and for (f) prosocial (vs. anti-social) behaviors similar to those of a control group of typically developing children aged two years on average. Overall, the feasibility of this paradigm proved to be good, resulting in high individual looking rates that were not affected by the presentation or the content of the tasks. Analyses of individual social-emotional abilities, supported by the visual preference patterns of each PIMD individual, firstly revealed strong—but expected—variability both within and between subjects, and secondly highlighted some individual task-specific abilities although few similarities between these individual results and those of the control group were found. These findings underline the great relevance of using this type of paradigm for assessing PIMD individuals and thus contribute to a better understanding of their social and emotional development.

Content Validation of Clinician-Reported Items for a Severity Measure for CDKL5 Deficiency Disorder

CDKL5 deficiency disorder (CDD) results in early-onset seizures and severe developmental impairments. A CDD clinical severity assessment (CCSA) was previously developed with clinician and parent-report items to capture information on a range of domains. Consistent with US Food and Drug Administration (FDA) guidelines, content validation is the first step in evaluating the psychometric properties of an outcome measure. The aim of this study was to validate the content of the clinician-reported items in the CCSA (CCSA-Clinician). Eight neurologists leading the USA CDD Center of Excellence clinics were interviewed using the "think aloud" technique to critique 26 clinician-reported items. Common themes were aggregated, and a literature search of related assessments informed item modifications. The clinicians then participated in 2 consensus meetings to review themes and finalize the items. A consensus was achieved for the content of the CCSA-Clinician. Eight of the original items were omitted, 11 items were added, and the remaining 18 items were revised. The final 29 items were classified into 2 domains: functioning and neurologic impairments. This study enabled refinement of the CCSA-Clinician and provided evidence for its content validity. This preliminary validation is essential before field testing and further validation, in order to advance the instrument toward clinical trial readiness.

Musical interaction with children and young people with severe or profound intellectual and multiple disabilities: a scoping review

This scoping review addresses peer-reviewed research on musical interaction with children and young people with severe/profound intellectual and multiple disabilities (S/PIMD). Twenty-five articles published between the years 2000 and 2020 met the inclusion criteria. A narrative synthesis was used to summarise and evaluate different features, including participant characteristics, study design and methods, type of musical interaction, the abilities and behaviours in focus, reported benefits, promising components of musical interaction, and quality appraisal of the studies. The results revealed a variation in participant characteristics and study designs, where small-sample descriptive case studies were most common. In terms of the type of musical interaction, active music therapy was the most commonly used approach, followed by technology-mediated and multisensory musical activities. In terms of abilities and behaviours, a large majority of the studies focused on social interaction and communication, followed by engagement, attention and affect. Six categories were identified as promising components of musical interaction: the responsivity of the interaction partner, singing songs, structure and predictability in the activities, long-term interventions, technology-mediated and multisensory musical activities, and a therapeutic alliance between interaction partners. Based on this review, we discuss future research and practical implications for musical interaction and music therapy for children and young people with S/PIMD.

Psychometric evaluation of the Chinese version of the Toronto Hospital Alertness Test

Background

Alertness is an important part of attention which is different from the opposite of sleepiness. This study aimed to translate and assess the measurement properties of the Toronto Hospital Alertness Test (THAT) in Hong Kong Chinese population.

Methods

The standard forward-backward translation procedure and cognitive debriefing were conducted to obtain the Chinese THAT. One hundred Chinese adults completed the Chinese THAT, the Center for Epidemiological Studies Depression Scale (CES-D), the Pittsburgh Sleep Quality Index (PSQI), and the Athens Insomnia Scale (AIS) by telephone interviews.

Results

The factorial validity was assessed by confirmatory factor analysis, and the internal reliability was examined by coefficient omega. The two negatively worded items of the THAT had low factor loadings and were removed. One more item was removed based on the modification indices of the eight-item model. The remaining seven-item THAT showed satisfactory unidimensionality with root mean square error of approximation (RMSEA) = 0.06, standardized root mean square residual (SRMR) = 0.08, and comparative fit index (CFI) = 1.00. The coefficient omega of the seven-item Chinese THAT was 0.80 (95% CI: 0.74–0.86). Convergent validity was demonstrated with THAT moderately associated with CES-D (r = − 0.45, P < 0.01), PSQI (r = − 0.40, P < 0.01), and AIS (r = − 0.45, P < 0.01).

Conclusions

The Chinese version of THAT demonstrated acceptable reliability and validity in a Chinese population.

Health profiles in people with intellectual developmental disorders

Objective. To better understand the health profiles of people with intellectual disability (ID), focusing on the variables that are associated with a poorer health status. Materials and methods. Data were collected from the Survey on Disability, Personal Autonomy and Dependency (EDAD 2008) of the Spanish National Statistics Institute (INE). The health data of 2 840 subjects with IDD were analyzed in order to verify the impact of different variables on their health profiles. Results. People with severe and profound levels of IDD presented a higher number of medical diagnoses.At residence centers there was a larger proportion of individuals with a higher prevalence of chronic diseases and more severe conditions; age also was an important factor. Conclusion. The health profiles of individuals with IDD differ depending on the severity level of their IDD and their degree of institutionalization. Further research is needed to provide better health care for people with IDD.

A randomised controlled trial on evaluation of the clinical efficacy of massage therapy in a multisensory environment for residents with severe and profound intellectual disabilities: a pilot study

BACKGROUND

Recent literature has suggested that relaxation activities can reduce the challenging behaviours of people with intellectual disabilities, particularly in severe and profound grades, due to the counteractive effect of muscle relaxation on emotional frustration or psychological distress. Despite having inconclusive evidence, multisensory environment (MSE) and massage therapy (MT) are the commonly used approaches to relaxation among these people. However, these two approaches have not yet practised or tested in combination for reducing these people's challenging behaviours.

METHODS

A preliminary clinical efficacy trial was conducted to evaluate the effects of MT, MSE and their combined use for residents with intellectual disabilities in a long-term care facility on reducing their challenging behaviours. Eligible residents were recruited and randomly assigned to one of the four study groups (n = 11-12 per group), that is, MT in MSE, MSE alone, MT alone or usual care, for a 10-week intervention after a 1-month washout period. Outcome measures, including the Behaviour Problem Inventory, pulse and respiration rates, Behaviour Checklist and Alertness Observation Checklist, were assessed at recruitment and immediately following the interventions.

RESULTS

A total of 42 participants (17 men and 25 women) completed the study. There were no significant differences in frequency and severity of challenging behaviours and most of the outcome measures between the four groups at post-test. Nevertheless, there were statistical significant differences on the active and inactive state (Alertness Observation Checklist) between the three treatment and control groups. Many participants in the three treatment groups changed from an active to inactive state (i.e. reduced activity levels) throughout the interventions, especially the MT in MSE. Such inactivity might suggest the participants' brief exhaustion followed by a period of alertness during the treatment activities. But their attention span and social contact to the immediate environment could still be maintained.

CONCLUSIONS

Participants of MT in multisensory environment acquired more inactive state than the other study groups. This inactive state indicates a state of 'passive alertness', which is more likely in a relaxing manner.

The Effects of a Power-Assisted Exercise Intervention on Alertness in People With Profound Intellectual and Multiple Disabilities

One of the benefits of physical activity in people with profound intellectual and multiple disabilities (PIMD) is an increase in alertness. This study investigated the effect of a power-assisted exercise intervention on alertness and the relationship of this effect to the level of additional motor and visual impairments in people with PIMD. A randomized controlled trial design (N = 37) was used with five measurements. Using individual plots and multilevel analysis, differences in change of alertness over time were analyzed between the intervention and control group, as was the relationship of changes to additional impairments. Considerable variation in alertness over time was found. The results showed no difference between the control and intervention groups in terms of alertness. No relationship with additional impairments was found. This study underlines the importance of looking at the effectiveness of interventions for people with PIMD because those interventions may not be as effective as expected.

An ecological method for the sampling of nonverbal signalling behaviours of young children with profound and multiple learning disabilities (PMLD)

BACKGROUND

Profound and multiple learning disabilities (PMLD) are a complex range of disabilities that affect the general health and well-being of the individual and their capacity to interact and learn.

METHOD

We developed a new methodology to capture the non-symbolic signalling behaviours of children with PMLD within the context of a face-to-face interaction with a caregiver to provide analysis at a micro-level of descriptive detail incorporating the use of the ELAN digital video software.

CONCLUSION

The signalling behaviours of participants in a natural, everyday interaction can be better understood with the use of this innovation in methodology, which is predicated on the ecology of communication. Recognition of the developmental ability of the participants is an integral factor within that ecology. The method presented establishes an advanced account of the modalities through which a child affected by PMLD is able to communicate.

Assistive technology to help persons in a minimally conscious state develop responding and stimulation control: Performance assessment and social rating

BACKGROUND

Post-coma persons in a minimally conscious state (MCS) and with extensive motor impairment and lack of speech tend to be passive and isolated.

OBJECTIVE

This study aimed to (a) further assess a technology-aided approach for fostering MCS participants' responding and stimulation control and (b) carry out a social validation check about the approach.

METHODS

Eight MCS participants were exposed to the aforementioned approach according to an ABAB design. The technology included optic, pressure or touch microswitches to monitor eyelid, hand or finger responses and a computer system that allowed those responses to produce brief periods of positive stimulation during the B (intervention) phases of the study. Eighty-four university psychology students and 42 care and health professionals were involved in the social validation check.

RESULTS

The MCS participants showed clear increases in their response frequencies, thus producing increases in their levels of environmental stimulation input, during the B phases of the study. The students and care and health professionals involved in the social validation check rated the technology-aided approach more positively than a control condition in which stimulation was automatically presented to the participants.

CONCLUSIONS

A technology-aided approach to foster responding and stimulation control in MCS persons may be effective and socially desirable.

Deep Assessment: A Novel Framework for Improving the Care of People with Very Advanced Alzheimer's Disease

Best practice in understanding and caring for people with advanced Alzheimer's disease presents extraordinary challenges. Their severe and deteriorating cognitive impairments are such that carers find progressive difficulty in authentically ascertaining and responding to interests, preferences, and needs. Deep assessment, a novel multifaceted framework drawn from research into the experiences of others with severe cognitive impairments, has potential to empower carers and other support professionals to develop an enhanced understanding of people with advanced Alzheimer's disease and so deliver better calibrated care in attempts to maximize quality of life. Deep assessment uses a combination of techniques, namely, Behaviour State Observation, Triangulated Proxy Reporting, and Startle Reflex Modulation Measurement, to deliver a comprehensive and deep assessment of the inner states (awareness, preferences, likes, and dislikes) of people who cannot reliably self-report. This paper explains deep assessment and its current applications. It then suggests how it can be applied to people with advanced Alzheimer's disease to develop others' understanding of their inner states and to help improve their quality of life. An illustrative hypothetical vignette is used to amplify this framework. We discuss the potential utility and efficacy of this technique for this population and we also propose other human conditions that may benefit from research using a deep assessment approach.

Visual habituation paradigm with adults with profound intellectual and multiple disabilities: a new way for cognitive assessment?

BACKGROUND

The use of common psychological assessment tools is invalidated with persons with PIMD. The aim of this study was to test the feasibility of using a visual habituation procedure with a group of adults with PIMD, to develop a new theoretical and practical framework for the assessment of cognitive abilities.

METHODS

To test the existence of the habituation/novelty reaction phenomenon with adults with PIMD, fifteen participants were exposed repeatedly to two different objects, following the principles of a participant-controlled procedure.

RESULTS

Both qualitative and quantitative analyses were carried out. Participants presented the same habituation profiles generally obtained in infancy research.

CONCLUSION

Stimulus presentation has a significant impact on the participants' visual behaviour and fixation measurement appears to be an interesting indicator as to how an individual with PIMD is able to process external information. The elaboration of perceptual tasks based on a visual habituation method is one of the major implications of these results.

Supporting self-managed leisure engagement and communication in post-coma persons with multiple disabilities

Post-coma persons affected by extensive motor impairment and lack of speech, with or without disorders of consciousness, need special support to manage leisure engagement and communication. These two studies extended research efforts aimed at assessing basic technology-aided programs to provide such support. Specifically, Study I assessed a program for promoting independent stimulation choice in four post-coma persons who combined motor and speech disabilities with disorders of consciousness (i.e., were rated between the minimally conscious state and the emergence from such state). Study II assessed a program for promoting independent television operation and basic communication in three post-coma participants who, contrary to those involved in Study I, did not have disorders of consciousness (i.e., had emerged from a minimally conscious state). The results of the studies were largely positive with substantial levels of independent stimulation choice and access for the participants of Study I and independent television operation and communication for the participants of Study II. The results were analyzed in relation to previous data in the area and in terms of their implications for daily contexts dealing with these persons.

Initiation of activities and alertness in individuals with profound intellectual and multiple disabilities

BACKGROUND

When providing activities to individuals with profound intellectual and multiple disabilities (PIMD), direct support persons (DSPs) often face questions that are, among other things, related to the alertness of the person with PIMD. While previous studies have revealed that stimulation might have a greater impact on levels of alertness than the internal conditions of the individual, they have also emphasized the importance of interaction in order to influence the level of alertness. Because the initiation of this interaction has been described as one of its core components, the present study has focused on the relationship between the stimuli presented, the initiation of the activity (by the person with PIMD or the DSP), and the level of alertness of the person with PIMD.

METHOD

Videotapes of the one-to-one interactions of 24 individuals with PIMD and their DSPs in multisensory environments have been scored using the Alertness Observation List. In a sequential analysis, the percentages of stimuli presented were related to the percentages of initiation. Furthermore, two other analyses focused on the relationship between the level of alertness and the preceding and subsequent percentages of initiation respectively.

RESULTS

The results show that high percentages of the activities are initiated by the DSPs. In addition, activities that were initiated by the individual with PIMD were preceded and followed by higher percentages of alert behaviour than those initiated by the DSP. Outcomes differed for the different types of stimuli.

CONCLUSIONS

These results have striking implications for the lives of individuals with PIMD. It is quite possible that DSPs often act too quickly, whereas they would be better off waiting for a reaction on the part of their client. In general, DSPs need to find a balance between being passive themselves and promoting in the individual with PIMD a state of being as active and alert as possible.

Non-pharmacological management of problematic sleeping in children with developmental disabilities

AIM

Sleep is important for underlying neural plasticity, and children with developmental disabilities suffer behavioural, emotional, cognitive, and sensory-motor issues that affect their wake and sleep states. Problematic sleeping can be hypothesized to have adverse effects on both of these areas in children with developmental disabilities. With this review, we aim to provide a benchmark in managing problematic sleeping in children with developmental disabilities.

METHOD

A literature search was conducted and data on the study descriptives, patient characteristics, study design, study-related factors, criteria applied to operationalize sleep and developmental disability, and sleep 'management' were collected. Each management strategy was tabulated and analysed.

RESULTS

We identified 90 studies involving 1460 children with developmental disabilities, of whom 61.6% were male. The highest proportion of studies, almost half, were in children with syndromes (44.4%), followed by studies in children with intellectual disabilities (18.9%). Non-pharmacological sleep management was primarily aimed at improving sleep quality (86.7%), followed by sleep-wake schedules and, to a certain extent, sleep regularity (42.2%). About 56.7% of the studies reported more than one approach. Studies mostly focused on disorders of initiating and maintaining sleep through a diversity of strategies and relied heavily on subjective measures to identify and monitor problematic sleeping. Sleep management approaches were primarily delivered at the level of the individual in the home setting. The number of management approaches per study was unrelated to the number of sleep problems discussed.

INTERPRETATION

Modifying sleep management strategies to meet the specific needs of children with developmental disabilities is encouraged, and studies that look beyond sleep quality or sleep quantity are required. It is also advocated that modifications to sleep hygiene, sleep regularity, and sleep ecology in a population with developmental disabilities are rigorously investigated. Finally, daytime somnolence should not be overlooked when aiming to optimize sleep in children with developmental disabilities across the ages and stages of their lives. There were several limitations in the research findings of problematic sleep in children with developmental disabilities. In general, the sleep problems and the developmental disabilities investigated were multicomponent in nature. It is likely that management approaches impacted those problems on multiple levels or through diverse 'therapeutic' pathways. There is a need for randomized controlled trials and more objective measures that quantify improved sleep or wake states.

Technology-aided programs for post-coma patients emerged from or in a minimally conscious state

Post-coma persons in a minimally conscious state (MCS) or emerged/emerging from such state (E-MCS), who are affected by extensive motor impairment and lack of speech, may develop an active role and interact with their environment with the help of technology-aided intervention programs. Although a number of studies have been conducted in this area during the last few years, new evidence about the efficacy of those programs is warranted. These three studies were an effort in that direction. Study I assessed a technology-aided program to enable six MCS participants to access preferred environmental stimulation independently. Studies II and III assessed technology-aided programs to enable six E-MCS participants to make choices. In Study II, three of those participants were led to choose among leisure and social stimuli, and caregiver interventions automatically presented to them. In Study III, the remaining three participants were led to choose (a) among general stimulus/intervention options (e.g., songs, video-recordings of family members, and caregiver interventions); and then (b) among variants of those options. The results of all three studies were largely positive with substantial increases of independent stimulation access for the participants of Study I and independent choice behavior for the participants of Studies II and III. The results were analyzed in relation to previous data and in terms of their implications for daily contexts working with MCS and E-MCS persons affected by multiple disabilities.

The nature of affect attunement used by disability support workers interacting with adults with profound intellectual and multiple disabilities

BACKGROUND

The interactions experienced by adults with profound intellectual and multiple disabilities (PIMD) with their disability support workers (DSWs) may have a large impact on life quality. However, defining good-quality interaction has presented challenges for this group. It has been suggested that in typically developing infant-mother dyads, the presence of affect attunement may be an indicator of quality. Affect attunement refers to the recasting of one person's affect by another with emphasis.

METHOD

The presence and nature of affect attunement in interactions between 21 pairs of adults with PIMD and their DSWs were explored in this study. Natural interactions were videorecorded for 21 pairs of adults with PIMD and their DSWs. The recordings were analysed for the presence and nature of affect attunement incidents, and analysed using descriptive statistics.

RESULTS

Affect attunement incidents were observed in 16 of the pairs. The DSW's attunement behaviour was in response to subtle, short duration behaviours of participants with PIMD.

CONCLUSION

These brief moments of connection may be a basis of good-quality interaction.

Observed changes in the alertness and communicative involvement of students with multiple and severe disability following in-class mentor modelling for staff in segregated and general education classrooms

BACKGROUND

The improvement of engagement and involvement in communicative and socially centred exchanges for individuals with multiple and severe disability (MSD) presents complex and urgent challenges to educators. This paper reports the findings of an intervention study designed to enhance the interactive skills of students with MSD using an in-class mentor model of staff development to improve the skills and strategies of their communication partners in two distinct educational settings.

METHODS

Observational data were collected on eight students with MSD and their 16 teachers and teachers' aides (paraprofessionals), using a multiple baseline across students design, replicated across special and general school setting types.

RESULTS

Results indicated variable improvements in student alertness and increased communicative interactions. In some cases significant differences in communicative involvement and awake-active-alert activity were observed.

CONCLUSIONS

These findings underline the complexity of variables involved in delivering educational and communicative interventions for staff working with this population. Implications for further research and application to daily practices in classrooms are discussed.

Microswitch-aided programs with contingent stimulation versus general stimulation programs for post-coma persons with multiple disabilities

OBJECTIVE

Assessing the impact of microswitch-aided programs with contingent stimulation on response engagement (Study I) and post-session alertness (Study II) of post-coma participants with multiple disabilities.

METHOD

Study I included three participants whose scores on the Coma Recovery Scale-Revised (CRS-R) were 11 or 13. Study II included three participants whose CRS-R scores were 19, 13, and 14. In both studies, the participants received sessions with contingent stimulation (i.e., sessions in which activation of a microswitch with an eyelid or hand response produced 15 s of preferred stimulation) and sessions with general, non-contingent stimulation (i.e., stimulation lasted throughout the sessions).

RESULTS

Study I showed an increase in response engagement/frequencies only during the contingent stimulation sessions. Study II showed that the participants' level of vigilance after those sessions was higher than after non-contingent stimulation sessions.

CONCLUSION

Microswitch-aided programs with contingent stimulation would be more beneficial than programs with general/non-contingent stimulation.

Occupation and communication programs for post-coma persons with or without consciousness disorders who show extensive motor impairment and lack of speech

These two studies were aimed at extending the assessment of technology-aided programs for post-coma persons with extensive motor impairment and lack of speech. Specifically, Study I assessed a new program arrangement, in which stimulation access and caregiver attention could be obtained with variations of the same response (i.e., single- versus double-hand closure) by three participants who were diagnosed at the upper level of the minimally conscious state at the start of the study. Study II was aimed at enabling two persons who had emerged from a minimally conscious state to engage in leisure activities, listen to audio-recordings of family members, and send and receive messages. The responses selected for these participants were hand pressure and eyelid closure, respectively. The results of both studies were positive. The participants of Study I increased their responding to increase their stimulation input and caregiver interaction. The participants of Study II managed to successfully select all the options the program included (i.e., the leisure options, as well as the family and communication options). General implications of the programs and the related technology packages for intervention with post-coma persons with multiple disabilities are discussed.

Catch the wave! Time-window sequential analysis of alertness stimulation in individuals with profound intellectual and multiple disabilities

BACKGROUND

While optimally activities are provided at those moments when the individual with profound intellectual and multiple disabilities (PIMD) is 'focused on the environment' or 'alert', detailed information about the impact that the design and timing of the activity has on alertness is lacking. Therefore, the aim of the present study is to shed light on the sequential relationship between different stimuli and alertness levels in individuals with PIMD.

METHOD

Video observations were conducted for 24 participants during one-on-one interactions with a direct support person in multisensory environments. Time-window sequential analyses were conducted for the 120 s following four different stimuli.

RESULTS

For the different stimuli, different patterns in terms of alertness became apparent. Following visual stimuli, the alertness levels of the individuals with PIMD changed in waves of about 20 s from 'active alert' to 'passive alert'. While auditory and tactile stimuli led to 'alert' reactions shortly after the stimulation, alertness levels decreased between seconds 20 and 120. Reactions to vestibular stimuli were only visible after 60 s; these were 'active alert' or 'withdrawn'.

CONCLUSIONS

The results of the present study show that individuals with PIMD show their reactions to stimuli only slightly, so that 'waves' might reflect the optimal alertness pattern for learning and development. Consequently, it is especially important that direct support persons follow and stimulate these individual 'waves' in the activities they provide to their clients.

Learn and apply: using multi-sensory storytelling to gather knowledge about preferences and abilities of children with profound intellectual and multiple disabilities--three case studies

Knowledge about the preferences and abilities of children with profound intellectual and multiple disabilities (PIMDs) is crucial for providing appropriate activities. Multi-sensory storytelling (MSST) can be an ideal activity for gathering such knowledge about children with PIMDs. The aim of this study was to analyse whether using MSST did lead to changes in teachers' knowledge about preferences and abilities and whether this knowledge was then applied in practice. Three dyads of children with PIMDs and their teachers read an MSST book 20 times during a 10-week period. A questionnaire designed to identify the teachers' current knowledge was filled in before the 1st and again after the 10th and 20th reading sessions. Also, the teachers were asked for their opinion about their newly gathered knowledge. In all three cases, changes in the teachers' knowledge were observed. However, teachers are insufficiently aware of their new knowledge and do not apply it in practice.

Towards improved ways of knowing children with profound multiple disabilities: introducing startle reflex modulation

OBJECTIVE

To propose startle reflex modulation (SRM) as an objective measure of emotions of children with profound multiple disabilities (PMD). Knowledge about emotion states of children with PMD is crucial to their individualised care and support. Proxy reporting, observational and physiological measures of emotion are reported in the literature. Despite advances in this science, the rigour of the findings and methods are contested. In this article, we introduce SRM; a neurophysiological measure untried with children with PMD, despite its well-known sensitivity to even subtle changes in affective processing without depending on explicit responses.

RESULTS

We propose a research agenda that aims to deliver a more comprehensive and accurate profile of the inner states of these children, based upon previous research undertaken using SRM.

CONCLUSION

It is suggested that this objective measure has potential to provide useful information about the inner emotional states of children with PMD.

Engagement in family activities: a quantitative, comparative study of children with profound intellectual and multiple disabilities and children with typical development

BACKGROUND

Participation is known to be of great importance for children's development and emotional well-being as well as for their families. In the International Classification of Functioning, Disability and Health - Children and Youth version participation is defined as a person's 'involvement in a life situation'. Engagement is closely related to involvement and can be seen as expressions of involvement or degree of involvement within a situation. This study focuses on children's engagement in family activities; one group of families with a child with profound intellectual and multiple disabilities (PIMD) and one group of families with children with typical development (TD) were compared.

METHODS

A descriptive study using questionnaires. Analyses were mainly performed by using Mann-Whitney U-test and Spearman's rank correlation test.

RESULTS

Engagement in family activities differed in the two groups of children. The children with PIMD had a lower level of engagement in most family activities even though the activities that engaged the children to a higher or lesser extent were the same in both groups. Child engagement was found to correlate with family characteristics mostly in the children with TD and in the children with PIMD only negative correlations occurred. In the children with PIMD child engagement correlated with cognition in a high number of listed family activities and the children had a low engagement in routines in spite of these being frequently occurring activities.

CONCLUSIONS

Level of engagement in family activities in the group of children with PIMD was lower compared with that in the group of children with TD. Families with a child with PIMD spend much time and effort to adapt family living patterns to the child's functioning.

The role of attention in the affective life of people with severe or profound intellectual disabilities

Although it is shown that attention plays an important role both in the onset and in the regulation of emotions in people without disabilities there is no information about how attention is related to emotions in people with severe or profound intellectual disability (ID). Therefore, in our study, we investigated the role of attention in the onset and regulation of the emotions of persons with severe or profound ID. We presented 27 participants with 4 staff-selected negative and 4 staff-selected positive stimuli. The situations were videotaped and their heart rate and attention was measured. Contrary to the expected higher attention to negative stimuli during the onset of negative emotions, we did not find differences in attention in the fourth to sixth second of stimulus presentation. However, in support of the emotion regulation theory of Gross (2008) we did find less attention to the negative stimuli than to the positive stimuli after these first 6s of stimuli presentation. As expected from research in people without disabilities, there was also a negative relationship between the heart rate and the probability of being attentive. Our results suggest that people with severe and profound ID use attentional deployment to regulate their emotions and that, as in people without disabilities, a low heart rate is associated with attention.

Physiological measurements as validation of alertness observations: an exploratory case study of three individuals with profound intellectual and multiple disabilities

Although observation largely takes into account the needs and abilities of individuals with profound intellectual and multiple disabilities, several difficulties are related to this assessment method as well. Our aim in this study was to investigate what possibilities the use of physiological measurements make available to validate alertness observations. Measurements of five physiological parameters were compared with video observations of three individuals with profound intellectual and multiple disabilities. Because our first findings are broadly in line with those of studies involving individuals in the general population, we hypothesize that physiological measurements can be used to validate alertness observations in individuals with profound intellectual and multiple disabilities. Future studies are needed to compensate for the limitations of this study and to answer ensuing questions.

Observing and Influencing Alertness in Individuals With Profound Intellectual and Multiple Disabilities in Multisensory Environments

While alertness is widely acknowledged as one of the most important preconditions for learning and development, individuals with profound intellectual and multiple disabilities (PIMD) experience a wide range of difficulties in the contact with their environment. The aim of the present study was to identify aspects of stimulation situations that influence the alertness levels of individuals in the target population.

Based on video recordings of 24 participants, alertness levels and environmental conditions were scored. Descriptive analyses and multilevel logistic regression analysis were used to identify the aspects of the stimulation situation that were related to occurrence of alertness.

The results show that visual stimuli (optimally in combination with auditory stimuli) produced the highest alertness levels. Furthermore, the effects of stimuli outweighed the effect of time. The role of direct support persons is thus especially important in alertness stimulation of individuals with PIMD.

Incidence and trends in psychopathology symptoms over time in adults with severe to profound intellectual disability

Individuals with intellectual disability (ID) have a high risk for developing comorbid psychopathology. While researchers have shown that symptoms of psychopathology remain relatively stable in children with ID over time, little research has been conducted to demonstrate symptom stability for adults with ID. Incidence of psychopathology symptoms was examined in 124 adults with severe to profound ID. Then, trends in symptoms of psychopathology over time were studied in 74 of those individuals who had data collected quarterly over the span of one year. Data from the Diagnostic Assessment for the Severely Handicapped-Second Edition (DASH-II) were evaluated for each of the 13 subscales, as well as the total DASH-II score. For all of the scales except PDD/Autism, symptoms did not fluctuate significantly over the one year period. The PDD/Autism scale revealed a significant change in symptoms from Time 1 to Time 3. The implications of these results are discussed.

Assessment of toileting difficulties in adults with intellectual disabilities: an examination using the profile of toileting issues (POTI)

A lack of toileting skills is one of many impairments that individuals with intellectual and developmental disabilities experience. Unfortunately, little research has focused on problems in this area including assessment, function, and treatment. A newly developed checklist, the Profile of Toileting Issues (POTI), is being considered for use to screen for toileting issues in this population, and to identify potential functions to target in treatment. The purpose of the current study was to examine the reliability of the POTI. Internal consistency was sound (α = .83) and interrater reliability was significant. The implications of these findings are included.
