The expression and assessment of emotions and internal states in individuals with severe or profound intellectual disabilities

The use of proxy measurement of internal states in people with intellectual disability: A scoping review

BACKGROUND

The measurement of internal states of people with an intellectual disability is challenging. Given these difficulties, proxy respondents are sometimes used. However, the literature provides some caution about the validity of the use of proxy respondents.

AIMS

This review aims to identify the available evidence regarding the use of proxy respondents in the measurement of internal states of people with intellectual disabilities.

METHOD

The Arksey and O'Malley scoping review framework was used for this review, refined with the Joanna Briggs Institute Methodology.

RESULTS

Results indicate there are some differences in the findings reported with respect to the efficacy of the use of proxy respondents. These may be due to a number of inconsistencies and weaknesses in examinations of their utility.

CONCLUSIONS

If proxy-reports are to be useful in understanding the internal states of people with intellectual disability, researchers need to address the shortcomings revealed by this review.

A concept for emotion recognition systems for children with profound intellectual and multiple disabilities based on artificial intelligence using physiological and motion signals

PURPOSE

This study proposes a concept for emotion recognition systems for children with profound intellectual and multiple disabilities (PIMD) based on artificial intelligence (AI) using physiological and motion signals.

METHODS

First, the heartbeat interval (R-R interval, RRI) of a child with PIMD was measured, and the correlation between the RRI and emotion was briefly tested in a preliminary experiment. Then, a concept based on AI for emotion recognition systems for children with PIMD was created using physiological and motion signals, and an emotion recognition system based on the proposed concept was developed using a random forest classifier taking as inputs the RRI, eye gaze, and other data acquired using low physical burden sensors. Subsequently, the developed emotion recognition system was evaluated, validating the proposed concept. Finally, we proposed a validated concept for emotion recognition systems.

RESULTS

A correlation was found between the RRI and emotion. The emotion recognition system was created based on the proposed concept and tested. According to the results, the recognition rate of "negative" and "not negative" of 70.4% ± 6.1% (Mean ± S.D.) of the developed emotion recognition system was higher than 48.5% ± 5.0% of an unfamiliar person used as a control.

CONCLUSION

The results indicate that the proposed concept for emotion recognition systems is useful for communicating with children with PIMD.

Application of the positive and negative affect scale in Chinese children with intellectual disability

The purpose is to test the applicability of the Positive and Negative Affect Scale (PANAS) to Chinese children with intellectual disabilities. The study was done by distributing the questionnaire to the parents through teachers online. Asked the parents to fill out the scale based on their observations of their children's daily life. The correlation coefficients between each item and the total score of the corresponding dimension ranged from 0.52 to 0.77. Factor analysis confirmed the establishment of the PA-NA two-factor structure of affect. A significant positive correlation existed between the NA and the challenging behavior. The Cronbach's α coefficient and split-half reliability of the PA scale were 0.87 and 0.85, and the Cronbach's α coefficient and split-half reliability of the NA scale were 0.85 and 0.83, respectively, higher than 0.80. It was concluded that PANAS has good applicability in Chinese children with intellectual disabilities.

The role of intellectual disability and emotional regulation in the autism-depression relationship

LAY ABSTRACT

Many people with autism and intellectual disability have significant levels of depressive symptoms. However, this relationship is not clear. For this reason, knowing the factors that are associated with having depression in autism and intellectual disability is important. Emotion regulation is associated with depression in autism spectrum disorder and intellectual disability. After evaluating a group of people with autism and intellectual disability, we found that people with mild intellectual disability have problems regulating their emotions which lead them to develop depressive symptoms. These findings suggest that interventions designed to prevent or reduce depressive symptoms in people with autism spectrum disorder and mild intellectual disability should include among their goals emotional regulation.

'Playing a guessing game': Recognising and responding to anxiety in children with intellectual disability

BACKGROUND

Children with intellectual disability are at greater risk of developing anxiety than the general population. Limited research has examined the challenges associated with recognising and responding to anxiety in children with intellectual disability, and its perceived impact.

AIM

This study aimed to explore anxiety in children with intellectual disability, from the child and parent perspective to better understand how parents and children recognise and respond to anxiety.

METHOD AND PROCEDURES

Six children with an intellectual disability (age range: 12-17, four boys) and their mothers participated in a semi-structured interview online. Interviews were transcribed verbatim and interpreted using thematic analysis.

OUTCOME AND RESULTS

Mothers elaborated on the difficulties with recognising signs of anxiety due to the impact of the child's primary diagnosis and the overlap of symptoms with co-occurring conditions. Mothers and children discussed the 'contagious' effect of anxiety within the household and how this influenced mothers' approaches to managing their child's anxiety. They reported that anxiety limited the meaningful activities in which children and families could engage.

CONCLUSIONS AND IMPLICATIONS

These findings highlight the importance of supporting mothers to recognise their children's anxiety and to assist them with strategies on how best to respond and cope. These findings have implications for future research, and practitioners working in this field.

Odor hedonic responses in children and young people with profound intellectual and multiple disabilities

Introduction

Odors are closely linked to emotions, play an important role in the well-being of individuals and can influence mood. Despite these crucial properties, the hedonic responses to odors of people with profound intellectual and multiple disabilities (PIMD) remain little explored.

Aim

This within-subjects study aims to examine whether children and young people with PIMD react in a differentiated way to odors evaluated as pleasant or unpleasant by neurotypical adults and, if so, with which behaviors. The influence of their global mood on their emotional responses to odors is also examined.

Method

Twenty children and young people (7-18 years old) with PIMD were exposed to four pairs of hedonically contrasted odors. A control stimulus was presented before each odorant. Five emotional responses, one physiological reaction (nausea reactions), and three responses reflecting approach toward or avoidance of the stimulus were recorded throughout the duration of the stimulus exposure. The participants' global mood status was measured before the start of the research with the French version of the Mood, Interest and Pleasure Questionnaire (Ross and Oliver, 2003).

Results

The results show that when exposed to pleasant odorants, participants kept their heads aligned with the odorant source longer, smiled longer, and produced more positive vocalizations. In contrast, unpleasant odorants elicit more pouts and grimaces. Nausea reactions occurred in the presence of unpleasant odorants. The hedonic responses were more marked during the second presentation of the stimuli. Participants with a higher MIPQ score showed significantly more emotional reactions to odors.

Conclusion

The results confirm the presence of olfactory preferences in participants with PIMD and the existence of a link between their mood, emotions and olfactory hedonic processing. They prompt the use of odors to support not only the cognitive development of this population, but also their mood and their emotional regulation abilities.

Emotional Well-Being of Children and Youth with Severe Motor and Communication Impairment: A Conceptual Understanding

BACKGROUND

Children and youth with severe motor and communication impairment (SMCI) have difficulty providing self-expression through typical speech, writing with a paper and pencil, or using a standard keyboard. Their emotional expressions can be missed by peers and novel caregivers.

PURPOSE

To describe the indicators and components of emotional experiences for children/youth with SMCI.

METHODS

Primary guardians of nine children/youth with SMCI were involved in photo/video data collection and follow-up qualitative interviews. Twenty-one familiar people (e.g., friends, family members, and/or care team) participated in semi-structured qualitative interviews.

RESULTS

A conceptual understanding of emotional well-being specific to the population has been developed consisting of nine themes, encompassed by four domains i) Core Attributes, ii) Personal Experiences, iii) Surroundings, iv) Expression and Reception.

CONCLUSIONS

Emotional experiences of children/youth with SMCI are diversely expressed. Primary guardian and familiar person insight can be amplified to positively impact care and participation.

Social and emotional characteristics of girls and young women with DDX3X-associated intellectual disability: a descriptive and comparative study

DDX3X variants are a common cause of intellectual disability (ID) in females, and have been associated with autism spectrum disorder and emotional-behavioural difficulties. In this study, we compared phenotypic data for 23 females with DDX3X variants, to 23 females with ID and other genetic diagnoses. We found a wide range of adaptive, social and emotional function within the DDX3X group. Autism characteristics did not differ between DDX3X and comparison groups, while levels of anxiety and self-injurious behaviour (SIB) were significantly higher in the DDX3X group. Within the DDX3X group, adaptive function, autism characteristics, anxiety and SIB scores were positively correlated, with evidence for group-specific associations with SIB. Future work is warranted to explore the multilevel mechanisms contributing to social and emotional development in individuals with DDX3X variants.

Utilising Interview Methodology to Inform the Development of New Clinical Assessment Tools for Anxiety in Autistic Individuals Who Speak Few or no Words

Autistic individuals with intellectual disability who speak few or no words are at high risk of anxiety but are underrepresented in research. This study aimed to describe the presentation of anxiety in this population and discuss implications for the development of assessments. Interviews were conducted with 21 parents/carers of autistic individuals and nine clinicians. Data were analysed using content analysis and interpretative phenomenological analysis. Anxiety behaviours described by parents/carers included increased vocalisation, avoidance and behaviours that challenge. Changes to routine were highlighted as triggering anxiety. Clinicians discussed the importance of identifying an individual's baseline of behaviour, knowing an individual well and ruling out other forms of distress. This study raises considerations for early identification of anxiety and for subsequent support.

Development and Psychometric Properties of a New Questionnaire to Assess Mental Health and Concerning Behaviors in Children and Young People with Autism Spectrum Disorder (ASD): The Assessment of Concerning Behavior (ACB) Scale

Although 70% of autistic children and young people meet criteria for co-occurring psychiatric conditions, there are few screening measures specifically for autistic individuals. We describe the development and validation of the Assessment of Concerning Behavior (ACB), an instrument co-developed with the autistic community to assess mental health and problematic/risky behaviors. Items include descriptions to facilitate symptom recognition by autistic people, and carers/professionals. The ACB was completed by 255 parents, 149 autistic children and young people and 30 teachers. Internal consistency, stability and validity was assessed. The ACB parent-version fit a two-factor model (internalizing and externalizing problems) and showed adequate test-retest reliability, internal consistency and construct validity. The ACB is a promising new measure for research and clinical use in autism.

Changes in the social-emotional functioning of young children with a significant cognitive and motor developmental delay across a two-year period

Children with a significant cognitive and motor developmental delay (SDD) are vulnerable for the development of (future) behavioral and mental health problems. To support children within this target group, knowledge on their social-emotional development is necessary. Therefore, in this paper, an explorative assessment of the changes in the social-emotional functioning of children with SDD over a two-year period was done. Yearly semi-structured interviews with one or more primary caregiver(s) of 25 children were conducted and analyzed on 13 domains of social-emotional functioning, according to an adapted version of the Scale for Emotional Development - Revised (SED-R). This study showed a lot of variation in individual and group patterns of change across the two-year period. Charting the social-emotional development in this target group is challenging and requires further in-depth analysis of individual trajectories as well as more fine-grained and long-term data collection.

A systematic review of the behaviours associated with depression in people with severe-profound intellectual disability

The assessment of depression in people with severe to profound intellectual disability (severe-profound ID) is challenging, primarily due to inability to report internal states such as mood, feelings of worthlessness and suicidal ideation. This group also commonly presents with challenging behaviours (e.g. aggression and self-injury) with debate about whether these behaviours should be considered 'depressive equivalents' or are sensitive for, but not specific to, depression in severe-profound ID. We conducted a systematic review exploring behaviours associated with depression and low mood in individuals with severe-profound ID. The review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (2009) guidelines. Three electronic databases were searched (Embase, PsycINFO and Ovid MEDLINE), and 13 studies were included and rated for quality. Few studies were rated as having high methodological quality. Behaviours captured by standard diagnostic schemes for depression (e.g. Diagnostic and Statistical Manual of Mental Disorders and International Classification of Diseases) showed a relationship with depression in severe-profound ID, including the two core symptoms (depressed affect and anhedonia), as well as irritability, sleep disturbance, psychomotor agitation, reduced appetite and fatigue. Challenging behaviours such as aggression, self-injury, temper tantrums, screaming and disruptive behaviour were associated with depression. Challenging behaviours show a robust relationship with depression. Whilst these behaviours may suggest an underlying depression, study limitations warrant caution in labelling them as 'depressive equivalents'. These limitations include not controlling for potential confounds (autism, other affective disorders and pain) and bias associated with comparing depressed/non-depressed groups on the same behavioural criteria used to initially diagnose and separate these groups. Future studies that use depressive measures designed for ID populations, which control for confounds and which explore low mood irrespective of psychiatric diagnosis, are warranted to better delineate the behaviours associated with depression in this population (PROSPERO 2018: CRD42018103244).

Orienting to affect in services for people with severe or profound intellectual disabilities: A UK-based investigation

BACKGROUND

This study argues for displays of affect by people with severe or profound intellectual disabilities to be analysed in the course of everyday interactions with the people who support them.

METHOD

Conversation analysis is applied to the affective displays of residents of a social care service for people with severe or profound intellectual disabilities to identify how such displays are taken up and form the basis for further action.

RESULTS

Three types of orientations to affect are identified: where the cause of the affect is unknown; where there is a proximal cause; and where the proximal cause is a prior action by a member of staff. Staff orient to affect as expressions of both feelings and cognitions, thereby providing the basis for self-determination.

CONCLUSIONS

Displays of affect are a communicative resource for those with severe or profound impairments and must be studied in situ if they are to inform policy and everyday practice.

Family accommodation of anxiety in a community sample of children on the autism spectrum

Anxiety is recognised as one of the most common co-occurring conditions for individuals with a diagnosis on the autism spectrum, with approximately 40 % of children on the spectrum receiving a clinical diagnosis of an anxiety disorder. To date, research has tended to focus upon understanding presentation and evaluating treatment, with little focus on assessing systemic factors, such as the way that family members accommodate the anxiety. This study aimed to investigate the relationship between parent and child anxiety levels and child autism characteristics on the four domains of family accommodation; Participation, Modification, Distress, and Consequence. A community sample (n = 132) of parents of children on the spectrum completed questionnaires on their child's autism characteristics and anxiety symptomatology as well as their own levels of anxiety and family accommodation behaviours. Regression models identified specific aspects of child anxiety as well as parent anxiety as predictive of family accommodation, with the child's difficulties with uncertainty being a consistent predictor of all four domains. Clinical and research implications of this study, including the importance of understanding similarities or differences in the nature and consequence of family accommodation in children on the autism spectrum, are discussed.

Anxiety-associated and separation distress-associated behaviours in Angelman syndrome

BACKGROUND

Anxiety is considered a 'frequent' feature in the clinical criteria for Angelman syndrome; however, the nature and severity of anxiety symptoms have not been well characterised in this population. Anxiety behaviours, especially in response to separation from a preferred caregiver, have been described clinically but have not yet been explored empirically.

METHOD

This study used a combination of standardised and clinician-derived survey items to assess the frequency, nature and severity of behaviours associated with anxiety and separation distress in 100 individuals with Angelman syndrome. Family (e.g. income and maternal education) and individual (e.g. age, sex, genetic subtype, sleep difficulties and aggressive behaviours) variables were also gathered to assess possible predictors of higher anxiety levels. Approximately half of the sample was seen in clinic and assessed with standardised measures of development and daily functioning, allowing for an additional exploration of the association between anxiety symptoms and extent of cognitive impairment.

RESULTS

Anxiety concerns were reported in 40% of the sample, almost 70% were reported to have a preferred caregiver and over half displayed distress when separated from that caregiver. Individuals with the deletion subtype and individuals who are younger were less likely to have anxiety behaviours. Sleep difficulties and aggressive behaviour consistently significantly predicted total anxiety, the latter suggesting a need for future studies to tease apart differences between anxiety and aggression or anger in this population.

CONCLUSIONS

Anxiety concerns, especially separation distress, are common in individuals with Angelman syndrome and represent an area of unmet need for this population.

Identification of emotions and physiological response in individuals with moderate intellectual disability

According to Ekman's model, the basic emotions are anger, disgust, fear, happiness, sadness, and surprise. These emotions are universal and have an adaptative function. However, studies on these emotions among individuals with moderate intellectual disability (MID) are limited, mainly owing to issues in sample size and sample homogeneity. The present study aimed to explore differences between a MID group (n = 10) and a non-MID control group (n = 10) in 1) the identification of basic emotions; and 2) the physiological response with images related to fear, happiness, sadness, anger, and disgust, as well as images with neutral and sexual content. A total of 29 images from The International Affective Picture System and a biofeedback measurement system were used. The results showed no statistically significant differences in the identification of the basic emotions of fear, sadness, and disgust. However, statistically significant differences were found for happiness (p = .008), anger (p = .02), and neutral images (p = .02), and minor statistically significant differences were found for images with sexual content (p < .01) in MID individuals with respect to the control group. The MID group's physiological response was lower compared with the control group, with statistically significant differences for all emotional visual stimuli. This preliminary study showed important and interesting results for the study of emotions and sexuality in MID. Future studies should consider the sample size, sex and age comparisons, and the different levels of intellectual disability.

Teacher responses to anxiety-related behaviours in students on the autism spectrum

BACKGROUND

At least 50% of students on the autism spectrum experience clinical or subclinical levels of anxiety but there is scant research on how teachers respond to anxiety in children on the spectrum.

AIMS

To compare teacher responses to anxiety-related behaviour in students who do and do not have a diagnosis on the spectrum using the Teacher Responses to Anxiety in Children (TRAC).

METHODS AND PROCEDURES

Teachers (N = 64), predominantly from mainstream primary schools, completed an online survey comprised of a demographic questionnaire and two versions of the TRAC, one for students without autism and one for students with autism.

OUTCOMES AND RESULTS

Teachers report differences in the way they would likely respond to anxiety-related behaviours observed in students with and without autism. Teachers reported being more likely to use anxiety-promoting responses for students with autism who are showing behaviours indicative of general and separation anxiety, but not when they are showing behaviours indicative of social anxiety. Whilst there was no significant difference in the overall likelihood of use of autonomy-promoting responses between groups, there were differences in the likelihood of using specific autonomy-promoting responses dependent upon diagnosis and type of anxiety.

CONCLUSIONS AND IMPLICATIONS

Teachers report they are likely to respond differently to anxiety-related behaviours of students on the autism spectrum but the impact of this on the behaviour of these students is yet to be determined. Professional development is a priority to increase teacher knowledge about anxiety-related behaviours in students with autism and the ways in which teachers' responses may promote or reduce anxiety and autonomy.

Parent descriptions of the presentation and management of anxiousness in children on the autism spectrum

The complex interaction between anxiety and autism has led to debate about the presentation of anxiety in individuals on the spectrum and questions about the extent to which traditional checklists assess the entire range of symptomatology. Moreover, studies to date have not explored how the presentation of anxiety may differ between settings. Through a combination of open-ended questions, closed questions and standardised measures, parents of 173 children (aged 6–13) on the autism spectrum provided (1) descriptors of their child’s anxiety at home, school and in the community and (2) strategies used to reduce their child’s anxiety in each setting. Over half (52.6%) felt their child was anxious at home, 77.6% at school and 76.2% in the community. Parents reported differing presentations of anxiety between settings, with the majority of descriptions relating to observable, behavioural changes (e.g. hides/shuts down, repetitive behaviours) rather than cognitive or physiological signs. Parents also reported using different strategies across settings. The use of open-ended questions allowed the identification of signs of anxiety not explored within traditional questionnaires and highlighted the potential for signs to vary across settings. This knowledge is critical to inform the development or adaptations of anxiety measures and interventions.

Identifying perception behaviours in people with profound intellectual and multiple disabilities

BACKGROUND

To support people with profound intellectual and multiple disabilities (PIMD), it is essential to understand how they experience their environment. Insight into perception behaviour may provide an entry point for improved understanding.

MATERIALS AND METHODS

A random sample of a 30-min video registration of five participants with PIMD was used to code behaviours per second based on an ethogram containing 157 different perception behaviours in nine categories.

RESULTS

Eighty-nine different perception behaviours were observed, of which movements with eyes, head and arms were most common. The senses used most were seeing, hearing and touching. Finally, the function of five perception patterns was established in relation to their function:awareness, focusing attention and tension regulation.

CONCLUSIONS

Close observation using an observation ethogram provides insight into how people with PIMD perceive their environment.

Self-Injury in Autism Spectrum Disorder and Intellectual Disability: Exploring the Role of Reactivity to Pain and Sensory Input

This paper provides information about the prevalence and topography of self-injurious behavior in children and adults with autism spectrum disorder and intellectual disability. Dominant models regarding the etiology of self-injury in this population are reviewed, with a focus on the role of reactivity to pain and sensory input. Neuroimaging studies are presented and suggestions are offered for future research.

Enhanced Nociception in Angelman Syndrome Model Mice

Angelman syndrome (AS) is a severe neurodevelopmental disorder caused by mutation or deletion of the maternal UBE3A allele. The maternal UBE3A allele is expressed in nearly all neurons of the brain and spinal cord, whereas the paternal UBE3A allele is repressed by an extremely long antisense transcript (UBE3A-ATS). Little is known about expression of UBE3A in the peripheral nervous system, where loss of maternal UBE3A might contribute to AS phenotypes. Here we sought to examine maternal and paternal Ube3a expression in DRGs neurons and to evaluate whether nociceptive responses were affected in AS model mice (global deletion of maternal Ube3a allele; Ube3a^m-/p+). We found that most large-diameter proprioceptive and mechanosensitive DRG neurons expressed maternal Ube3a and paternal Ube3a-ATS In contrast, most small-diameter neurons expressed Ube3a biallelically and had low to undetectable levels of Ube3a-ATS Analysis of single-cell DRG transcriptomes further suggested that Ube3a is expressed monoallelically in myelinated large-diameter neurons and biallelically in unmyelinated small-diameter neurons. Behavioral responses to some noxious thermal and mechanical stimuli were enhanced in male and female AS model mice; however, nociceptive responses were not altered by the conditional deletion of maternal Ube3a in the DRG. These data suggest that the enhanced nociceptive responses in AS model mice are due to loss of maternal Ube3a in the central, but not peripheral, nervous system. Our study provides new insights into sensory processing deficits associated with AS.SIGNIFICANCE STATEMENT Angelman syndrome (AS) is a neurodevelopmental disorder caused by loss or mutation of the maternal UBE3A allele. While sensory processing deficits are frequently associated with AS, it is currently unknown whether Ube3a is expressed in peripheral sensory neurons or whether maternal deletion of Ube3a affects somatosensory responses. Here, we found that Ube3a is primarily expressed from the maternally inherited allele in myelinated large-diameter sensory neurons and biallelically expressed in unmyelinated small-diameter neurons. Nociceptive responses to select noxious thermal and mechanical stimuli were enhanced following global, but not sensory neuron-specific, deletion of maternal Ube3a in mice. These data suggest that maternal loss of Ube3a affects nociception via a central, but not peripheral mechanism, with implications for AS.

Pain underreporting associated with profound intellectual disability in emergency departments

BACKGROUND

Little information is available regarding the visits made by persons with profound intellectual disability (PID) to general hospital emergency departments (ED). This study aims to know whether persons with PID who attend ED are given the same type of diagnoses as people with no such disability.

METHODS

Over a period of 18 months, we gathered data from all non-scheduled visits to an ED by persons with PID to identify the reason for consultation (according to the classification used by the Spanish Society for Emergency Nursing) and the final diagnosis upon discharge. The results were compared with data obtained from a control group of people with no ID who attended an ED for any reason during the same period.

RESULTS

Somatic complaints were the main reason for ED attendance among persons with PID (90% of consultations). These complaints were more often related to the central nervous system than was the case among non-ID patients (16 vs. 4.7%), whereas other kinds of non-central nervous system somatic complaint were less common among persons with PID (74 vs. 91%). A diagnosis implying physical pain was given less often to people with PID than to controls (3 vs. 20%).

CONCLUSIONS

The results suggest that persons with PID are less able to conceptualise and communicate information about their symptoms, especially as regards pain, and that this influences the diagnosis they are given when attending an ED. Professionals working in this environment need to be aware of this possibility so as not to underestimate or overlook such symptoms and the illnesses related to them.

Triangulated Proxy Reporting: a technique for improving how communication partners come to know people with severe cognitive impairment

PURPOSE

This paper explains and demonstrates the pilot application of Triangulated Proxy Reporting (TPR); a practical technique for enhancing communication around people who have severe cognitive impairment (SCI).

METHODS AND RESULTS

An introduction explains SCI and how this impacts on communication; and consequently on quality of care and quality of life. This is followed by an explanation of TPR and its origins in triangulation research techniques. An illustrative vignette explicates its utility and value in a group home for a resident with profound multiple disabilities. The Discussion and Conclusion sections propose the wider application of TPR for different cohorts of people with SCIs, their communication partners and service providers.

CONCLUSIONS

TPR presents as a practical technique for enhancing communication interactions with people who have SCI. The paper demonstrates the potential of the technique for improving engagement amongst those with profound multiple disabilities, severe acquired brain injury and advanced dementia and their partners in and across different care settings. Implications for Rehabilitation Triangulated Proxy Reporting (TPR) shows potential to improve communications between people with severe cognitive impairments and their communication partners. TPR can lead to improved quality of care and quality of life for people with profound multiple disabilities, very advanced dementia and severe acquired brain injury, who otherwise are very difficult to support. TPR is a relatively simple and inexpensive technique that service providers can incorporate into practice to improving communications between clients with severe cognitive impairments, their carers and other support professionals.

Biomusic: An Auditory Interface for Detecting Physiological Indicators of Anxiety in Children

For children with profound disabilities affecting communication, it can be extremely challenging to identify salient emotions such as anxiety. If left unmanaged, anxiety can lead to hypertension, cardiovascular disease, and other psychological diagnoses. Physiological signals of the autonomic nervous system are indicative of anxiety, but can be difficult to interpret for non-specialist caregivers. This paper evaluates an auditory interface for intuitive detection of anxiety from physiological signals. The interface, called "Biomusic," maps physiological signals to music (i.e., electrodermal activity to melody; skin temperature to musical key; heart rate to drum beat; respiration to a "whooshing" embellishment resembling the sound of an exhalation). The Biomusic interface was tested in two experiments. Biomusic samples were generated from physiological recordings of typically developing children (n = 10) and children with autism spectrum disorders (n = 5) during relaxing and anxiety-provoking conditions. Adult participants (n = 16) were then asked to identify "anxious" or "relaxed" states by listening to the samples. In a classification task with 30 Biomusic samples (1 relaxed state, 1 anxious state per child), classification accuracy, sensitivity, and specificity were 80.8% [standard error (SE) = 2.3], 84.9% (SE = 3.0), and 76.8% (SE = 3.9), respectively. Participants were able to form an early and accurate impression of the anxiety state within 12.1 (SE = 0.7) seconds of hearing the Biomusic with very little training (i.e., < 10 min) and no contextual information. Biomusic holds promise for monitoring, communication, and biofeedback systems for anxiety management.

The Diagnostic Guideline for Anxiety and Challenging Behaviour for Persons with Intellectual Disabilities: Preliminary Outcomes on Internalizing Problems, Challenging Behaviours, Quality of Life and Clients' Satisfaction

BACKGROUND

People with intellectual disabilities are vulnerable to develop psychopathology (in particular anxiety) and related challenging behaviour. A diagnostic guideline was developed to support professionals to better diagnose and thus treat psychopathology and related CB. This study examined preliminary outcomes from the application of this guideline.

METHOD

A comparative multiple case study with an experimental and a control condition.

RESULTS

The application of the guideline showed a trend of decreases of internalizing problems (P = 0.07) and anxiety/depressed problems (P = 0.09). We found no statistically significant decreases of externalizing problems and no increases in perceived quality of life as compared with care as usual. Clients were not more satisfied with the support they received for coping with their emotional and behaviour problems.

CONCLUSION

The application of the Diagnostic Guideline for Anxiety and Challenging Behaviour did not show statistically significant changes in externalizing problems and Quality of Life. Despite the small sample size of n = 59, we did find a trend in decreasing internalizing problems and anxiety/depressed problems. Further research into either or not confirming these trends is recommended.

Paralinguistic abilities of adults with intellectual disability

The aim of this research was to determine the ability level of paralinguistic production and comprehension in adults with intellectual disability (ID) with regard to the level of their intellectual functioning and presence of co-morbid psychiatric conditions or dual diagnosis (DD). The sample consisted of 120 participants of both genders, ranging in age between 20 and 56 years (M=31.82, SD=8.702). Approximately 50% of the sample comprised participants with a co-existing psychiatric condition. Each of these two sub-samples (those with ID only and those with DD) consisted of 25 participants with mild ID and 35 participants with moderate ID. The paralinguistic scale from The Assessment Battery for Communication (ABaCo; Sacco et al., 2008) was used to assess the abilities of comprehension and production of paralinguistic elements. The results showed that the participants with mild ID are more successful than the participants with moderate ID both in paralinguistic comprehension tasks (p=.000) and in paralinguistic production tasks (p=.001). Additionally, the results indicated the presence of separate influences of both ID levels on all of the paralinguistic abilities (F [116]=42.549, p=.000) and the existence of DD (F [116]=18.215, p=.000).

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.

Psychosocial experiences of chronic illness in individuals with an intellectual disability: A systematic review of the literature

BACKGROUND

Increased life expectancy has led to an increase in diagnoses of chronic illness in people with an intellectual disability; despite this increase, research about the psychological impact is rare. This review explored the psychosocial experiences of chronic illness in adults with an intellectual disability, revealing potential predictors and moderators of these experiences.

METHODS

Online databases were systematically searched to identify relevant literature, using predefined inclusion criteria. Of the 25,058 titles initially identified, 4 were included, that is, those collecting data on people with an intellectual disability and diagnosed with cancer (n = 2), chronic pain (n = 1) and diabetes (n = 1).

RESULTS

Narrative synthesis of the data identified six themes, namely, (1) delayed diagnosis, (2) information, communication and understanding, (3) negative psychological consequences, (4) negative physical consequences, (5) social perception and (6) social support.

CONCLUSIONS

There are unmet needs within this population, including a lack of assistance in understanding their illness. A substantial gap in the literature should be addressed through further empirical work.

Applying the Verona coding definitions of emotional sequences (VR-CoDES) in the dental context involving patients with complex communication needs: An exploratory study

OBJECTIVE

The VR-CoDES has been previously applied in the dental context. However, we know little about how dental patients with intellectual disabilities (ID) and complex communication needs express their emotional distress during dental visits. This is the first study explored the applicability of the VR-CoDES to a dental context involving patients with ID.

METHODS

Fourteen dental consultations were video recorded and coded using the VR-CoDES, assisted with the additional guidelines for the VR-CoDES in a dental context. Both inter- and intra-coder reliabilities were checked on the seven consultations where cues were observed.

RESULTS

Sixteen cues (eight non-verbal) were identified within seven of the 14 consultations. Twenty responses were observed (12 reducing space) with four multiple responses. Cohen's Kappa were 0.76 (inter-coder) and 0.88 (intra-coder).

CONCLUSION

With the additional guidelines, cues and responses were reliably identified. Cue expression was exhibited by non-verbal expression of emotion with people with ID in the literature. Further guidance is needed to improve the coding accuracy on multiple providers' responses and to investigate potential impacts of conflicting responses on patients.

PRACTICE IMPLICATIONS

The findings provided a useful initial step towards an ongoing exploration of how healthcare providers identify and manage emotional distress of patients with ID.

Quetiapine responsive catatonia in an autistic patient with comorbid bipolar disorder and idiopathic basal ganglia calcification

BACKGROUND

Bipolar disorder (BD) has been linked with the manifestation of catatonia in subjects with autism spectrum disorders (ASD). Idiopathic basal ganglia calcification (IBGC) is characterized by movement disorders and various neuropsychiatric disturbances including mood disorder.

CASE

We present a patient with ASD and IBGC who developed catatonia presenting with prominent dystonic feature caused by comorbid BD, which was treated effectively with quetiapine.

CONCLUSION

In addition to considering the possibility of neurodegenerative disease, careful psychiatric interventions are important to avoid overlooking treatable catatonia associated with BD in cases of ASD presenting with both prominent dystonic features and apparent fluctuation of the mood state.

Exploring experiences and understandings of pain in adults with intellectual disabilities

BACKGROUND

People with intellectual disabilities (ID) are at risk that their health problems, many of which cause pain, go unrecognised and untreated. Their understanding and personal experiences of pain have received little research attention.

METHOD

Information was collected from 15 adults with ID using semi-structured interviews about their experiences and understanding of pain. Transcripts were analysed using content analysis.

RESULTS

Participants described pain using negative meanings and strong imagery, with various causes of pain suggested, but said little about how they coped with pain. Participants varied in whether they reported pains to carers, some choosing to hide the experience. There seemed a general belief that others can tell when someone is in pain.

CONCLUSIONS

Conversations regarding pain with adults with ID are a real challenge; health-care staff need to think carefully about the questions they ask. Possessing verbal skills cannot be taken as an indication that pain will be communicated.

Recognition of facial expressions by alcoholic patients: a systematic literature review

BACKGROUND

Alcohol abuse and dependence can cause a wide variety of cognitive, psychomotor, and visual-spatial deficits. It is questionable whether this condition is associated with impairments in the recognition of affective and/or emotional information. Such impairments may promote deficits in social cognition and, consequently, in the adaptation and interaction of alcohol abusers with their social environment. The aim of this systematic review was to systematize the literature on alcoholics' recognition of basic facial expressions in terms of the following outcome variables: accuracy, emotional intensity, and latency time.

METHODS

A systematic literature search in the PsycINFO, PubMed, and SciELO electronic databases, with no restrictions regarding publication year, was employed as the study methodology.

RESULTS

The findings of some studies indicate that alcoholics have greater impairment in facial expression recognition tasks, while others could not differentiate the clinical group from controls. However, there was a trend toward greater deficits in alcoholics. Alcoholics displayed less accuracy in recognition of sadness and disgust and required greater emotional intensity to judge facial expressions corresponding to fear and anger.

CONCLUSION

The current study was only able to identify trends in the chosen outcome variables. Future studies that aim to provide more precise evidence for the potential influence of alcohol on social cognition are needed.

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.

See me, feel me. Using physiology to validate behavioural observations of emotions of people with severe or profound intellectual disability

BACKGROUND

Behavioural observations are the most frequently used source of information about emotions of people with severe or profound intellectual disabilities but have not yet been validated against other measures of emotion. In this study we wanted to validate the behavioural observations of emotions using respiration (rib cage contribution, total breath duration, inspiratory time, expiratory time, tidal volume, mean inspiratory flow, minute ventilation) and heart rate variability.

METHOD

Twenty-seven participants were presented with four negative and four positive stimuli. During the presentation the participants' respiration and heart rate variability was measured. Each behaviour of the participant was coded as emotive or not.

RESULTS

We found the hypothesised higher percentage rib cage contribution, marginal lower mean inspiratory flow and lower heart rate variability when the expressed emotions became more positive.

CONCLUSIONS

These results validate the use of behavioural observations to make inferences about emotions.

Investigating the relationship between observed mood and emotions in people with severe and profound intellectual disabilities

BACKGROUND

The measurement of subjective well-being in people with severe and profound intellectual disabilities (ID) is a difficult challenge. As they cannot self-report about their life satisfaction, because of severe communicative and cognitive limitations, behavioural observations of their emotions and moods are important in the measurement of their subjective well-being. It is, however, not known if observations of mood and emotion can be differentiated in people with severe and profound ID and if mood and emotions can give unique information about their affect. Therefore, the aim of this study is to examine the relationship between mood and emotions in people with severe and profound ID, using behavioural observations. As recommended in the literature, we investigated the frequency and intensity of the emotion separately.

METHOD

In a period of 3 weeks 27 participants with severe and profound ID were presented with four staff-selected negative and four staff-selected positive stimuli. During the presentation participants were videotaped using the observational method of Petry & Maes where each behaviour is coded on a 5-point scale, ranging from indicating a very negative emotion to indicating a very positive emotion. As a measure of mood, the staff completed the MIPQ in the beginning of the 3 weeks.

RESULTS

We found a positive relationship between mood and respectively the total emotion score and the frequency of the emotion when the stimuli were positive but not when the stimuli were negative. There was no relationship between mood and the intensity of the emotion.

CONCLUSIONS

Our results indicate that mood and emotions can be distinguished from each other using behavioural observations. Both can give specific information about the affective life of people with severe or profound ID. Moreover, if further research could replicate the results of this study, an implication is that the direct support workers should be aware of a decline in the frequency of their clients reactions to positive stimuli as this could indicate a decline in their mood.

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.

How facial expressions in a Rett syndrome population are recognised and interpreted by those around them as conveying emotions

Rett syndrome (RTT) is a neurodevelopmental disorder, including autonomic nervous system dysfunctions and severe communication impairment with an extremely limited ability to use verbal language. These individuals are therefore dependent on the capacity of caregivers to observe and interpret communicative signals, including emotional expressions. People in general, including therapists tend to focus on changes in facial expressions to interpret a person's emotional state or choices, but with this population it is difficult to know if the interpretations are correct. The aims of this study were to investigate if the Facial Action Coding System (FACS) could be used to identify facial expressions, and differentiate between those that expressed emotions and those that were elicited by abnormal brainstem activation in RTT. The sample comprised 29 participants with RTT and 11 children with a normal developmental pattern, exposed to six different musical stimuli during non-invasive registration of autonomic brainstem functions. The results indicate that FACS makes it possible both to identify facial expressions and to differentiate between those that stem from emotions and those caused by abnormal brainstem activation. This knowledge may be a great help to an uninitiated observer, who otherwise might incorrectly interpret the latter as an expression of emotion.

Technology-based programs to support forms of leisure engagement and communication for persons with multiple disabilities: two single-case studies

OBJECTIVE

To extend the assessment of technology-based programs for promoting stimulus choice and staff/caregiver calls or radio operation and text messaging.

METHOD

In Study I, the program involved a portable computer, commercial software, and a microswitch to allow a man with motor impairment and moderate intellectual disability to choose among preferred stimuli (e.g., songs and film clips) and persons to call. In Study II, the programs involved (a) a radio device and an electronic control unit or (b) a net-book computer and a global system for mobile communication. A woman with blindness and moderate intellectual disability used a microswitch to operate the radio or send and listen to text messages.

RESULTS

The participants succeeded in using the technology-aided programs through simple microswitch activations involving partial hand closure (Study I) or hand pressure (Study II).

CONCLUSION

Technology-based programs can provide persons with multiple disabilities relevant leisure and communication opportunities.

The tell-tale: what do heart rate; skin temperature and skin conductance reveal about emotions of people with severe and profound intellectual disabilities?

Identifying emotions in people with severe and profound intellectual disabilities is a difficult challenge. Since self-reports are not available, behaviour is the most used source of information. Given the limitations and caveats associated with using behaviour as the sole source of information about their emotions, it is important to supplement behavioural information with information from another source. As it is accepted that emotions consist of language, behaviour and physiology, in this article we investigated if physiology could give information about the emotions of people with severe and profound intellectual disabilities. To this aim we tested hypotheses derived from the motivational model of Bradley, Codispoti, Cuthbert, and Lang (2001) about the relation between heart rate and the valence of emotions and between heart rate, skin conductance and skin temperature and behavioural expressions of emotions of people with severe and profound intellectual disability. We presented 27 participants with 4 staff-selected negative and 4 staff-selected positive stimuli. The situations were videotaped and their heart rate, skin conductance and skin temperature was measured. Each behaviour of the participant was coded using the observational method developed by Petry and Maes (2006). As hypothesized, we found a lower heart rate when participants were presented with negative stimuli than when they were presented with positive stimuli in the first 6s of stimuli presentation. Their skin temperature was higher for the expression of low intensity negative emotions compared to the expression of low intensity positive emotions. The results suggest that, as with people without disability, heart rate and skin temperature can give information about the emotions of persons with severe and profound ID.
