Gesture-speech integration is related to vocabulary skills in children with developmental language disorder, Williams syndrome and typical development.

BACKGROUND: Individuals with developmental language disorder or Williams syndrome are reported to use more gestures than individuals with typical development. However, these two groups differ considerably in visuospatial and language skills, two skills that are hypothesized to shape gesture rate. AIMS: We first examined whether children with both developmental language disorder and children Williams syndrome do indeed use more gestures. Our second aim was to disentangle the role of vocabulary and visuospatial skills in the use of supplementary gestures (i.e., containing unique information). To account for participant heterogeneity, analyses included both group comparisons and vocabulary and visuospatial skills at an individual level. As a third aim, the role of visuospatial skills was further examined in relation to gestures containing spatial content. METHODS & PROCEDURES: In a cross-sectional group design, three participant groups watched and then retold a cartoon: children with typical development (n = 25), children with developmental language disorder (n = 25) and children/young people with Williams syndrome (n = 14). Their narrations were transcribed and hand gestures were coded based on gesture-speech integration (redundant, adds information to particular lexical items, gives information that is entirely absent from speech) and spatial content. Participants' expressive vocabulary and visuospatial skills were measured. OUTCOMES & RESULTS: Between-group comparisons showed that individuals with developmental language disorder or Williams syndrome did indeed use more gestures. Poisson loglinear modelling demonstrated that a relative higher use of supplementary gestures was determined by lower expressive vocabulary skills. Neither the group distinction nor visuospatial skills shaped the supplementary gesture rate nor spatial gesture rate. CONCLUSIONS & IMPLICATIONS: Regardless of neurodevelopmental condition or typical development, a higher use of supplementary gestures was influenced by expressive vocabulary skills. Children with lower vocabulary skills spontaneously capitalized on the multimodality of communication to express constituents that were not present in their verbal speech. This finding is a promising starting point for future gesture intervention studies examining whether implicit modelling of gesture use can encourage gestures even more in these children and if this allows them to achieve higher linguistic complexity. On a methodological note, the observed intra-group skill variability demonstrates that group comparisons need to be complemented with correlational measures accounting for skills at an individual level. WHAT THIS PAPER ADDS: What is already known on the subject Children with developmental language disorder and children with Williams syndrome are more inclined to use gestures than typically developing children. Research conducted in adults with typical development points towards the role of lexical and visuospatial skills in gesture use, but it is unclear how these skills shape gesture use in children with atypical development. What this paper adds to existing knowledge This study compares the rate of gestures that convey meaning that is not expressed in speech between the three aforementioned populations. Novel is the inclusion of the group distinction, individual lexical skills, and visuospatial skills in one encompassing statistical model. What are the potential or actual clinical implications of this work? The inclination to use gestures that replace speech is related to lexical skills. Visuospatial skills do not seem to play a role and should not be considered as a factor when thinking about gesture intervention. Understanding how gestures relate to specific skills is a first step to understanding how gesture interventions can bolster language production.

Describing the communicative profiles of young children with a significant cognitive and motor developmental delay.

The communicative behavior of young children with significant cognitive and motor developmental delays is generally considered to be limited, idiosyncratic and non-intentional. At present, changes between and within children over time regarding their communicative behavior are hard to detect. This article describes an exploratory observational study that draws on data from the first data point of 38 children who are participating in a longitudinal project on the developmental trajectories of children with significant cognitive and motor developmental delays. The aims of this study were to (a) describe the participants' communicative behavior in detail with communication-related variables that reflect differences across individuals, (b) create summarizing variables and (c) explore whether subgroups of children can be detected. A self-developed coding scheme and descriptive statistics combined with correlational analyses were used, followed by a principal component analysis and visual inspection of the outcome of this analysis. The within-group differences related to communicative behavior was characterized using 16 variables. Based on these variables, three overarching components were formulated: communication proficiency, Expressions of Discomfort and Rejection and Differentiation According to Focus. All participating children were found to be unique in terms of their component scores and the relationship among their component scores.

Piloting attachment psychoeducation provided to parents of children with severe disabilities: Testing the feasibility of a digital micro-intervention.

BackgroundA digital micro-intervention offering attachment psychoeducational videos was explored regarding its feasibility in parents of children with severe disabilities. Method: A mixed-methods study (including daily diaries and one-time questionnaires) with 16 parents (75.0% female) of children with severe disabilities (up to 10 years of age) was done during a three-week intervention. Results: Parents were positive about the video series and almost no drop-out occurred. The videos stimulated their learning and thinking and offered parents some personal meaning. Preliminary efficacy tests showed no major changes in parents' parenting self-efficacy (PSE) or perceptions of statements on parent-child attachment. Conclusions: The study showed promising results regarding the micro-interventions' acceptability and implementation. The limited efficacy testing did not show major changes in parents' PSE. Further research is needed to investigate the differential relevance of the micro-intervention, based on parents' needs, as well as its optimal embeddedness in a broader intervention trajectory.

Resilience and quality of life in young adults with a 22q11.2 deletion syndrome: a patient's perspective.

In the transition period between adolescence and young adulthood, individuals with 22q11.2DS are at an increased risk of developing severe psychiatric disorders. Various studies have focused on detecting risk factors, but until now protective factors are still understudied in 22q11.2DS. The current case-control study focuses on the role of resilience and quality of life (QoL) in young adults with 22q11.2DS and behavioural problems, in comparison with persons with an intellectual disability (ID) without a known genetic disorder. Self-report (and caregiver report) standardized questionnaires were used. Predictive general linear models were constructed to compare the resilience and quality of life across both groups (22q11.2DS vs ID-group) and to analyse the association between personal characteristics in both groups. Young adults with a 22q11.2DS show less resilience compared with both the general population norms and young adults with ID. Only a subscale of resilience (Acceptance of self and life) contributes to the reported level of QoL. Reported health problems are not related to resilience, but have an important effect on QoL. Our results suggest different factors are underlying resilience and the relation with QoL in 22q11.2DS and ID in general. These factors deserve more research and are important to take into account in clinical practice.

'We can't do it alone': Perceived social support in parents of children with a significant cognitive and motor developmental delay.

BACKGROUND: It is generally acknowledged that parent social support is an important target for intervention. To explore the specific needs of parents of young children with a significant cognitive and motor developmental delay (SDD), we aim to chart the sources and perceived sufficiency of the social support they receive. METHOD: Within the context of a broader project, 42 parents of a young child with SDD filled out a questionnaire on contextual factors, including information on social support. RESULTS: The majority of parents reported to receive (more than) sufficient support. Insufficiency is primarily reported with regard to practical support. Apart from the partner, grandparents of the child were the most common source of support. CONCLUSIONS: This study confirms the importance of professional support and work-life balance within this specific target group. Specific attention for practical support needs seems warranted considering the high basic care needs of these children.

The relation between gestures and stuttering in individuals with Down syndrome.

BACKGROUND: Evidence shows that neurotypical individuals who stutter use fewer gestures than those who do not stutter. Presently, no research exists about the interaction of stuttering and gestures in individuals with Down syndrome. METHOD: Twenty-nine individuals with Down syndrome (7-19 years) of whom 16 stuttered and 13 spoke fluently and 20 neurotypical children (3-10 years) of whom 8 stuttered and 12 spoke fluently participated in this study. In spontaneous speech transcriptions, stuttering events and gestures were coded. RESULTS: Comparisons of gesture frequency during stuttered and fluent speech inside the Down syndrome and neurotypical group show that the Down syndrome group uses significantly more gestures during stuttered than during fluent speech while no significant difference is seen in the neurotypical group. CONCLUSIONS: There is some preliminary evidence that individuals with Down syndrome try to compensate for their stuttering events, however, analyses on word level are necessary to confirm a successful compensation.

Looking back, looking forward: Methodological challenges and future directions in research on persons with profound intellectual and multiple disabilities.

BACKGROUND: Within the context of the Special Interest Research Group (SIRG) on Persons with Profound Intellectual and Multiple Disabilities (PIMD), researchers often discuss the methodological problems and challenges they are confronted with. The aim of the current article was to give an overview of these challenges. METHODS: The challenges are centred on six topics. These reflect the main components of a study's design: (a) participant demarcation, (b) participant recruitment, (c) data collection and instruments, (d) data analysis, (e) ethics/including the "voice" of persons with PIMD and (f) theoretical models. RESULTS: Next, to describing the specific challenges, possible solutions and pathways to address them are discussed. These are illustrated by recent studies by the authors and other researchers in the field. CONCLUSIONS: The current contribution wants to stimulate further discussion and exchange of ideas, and the development of creative research techniques.

In search of a novel way to analyze early communicative behavior.

The aim of this study was to develop a coding scheme that enables researchers and practitioners to conduct a detailed analysis of the communicative behavior of young children with significant cognitive and motor developmental delays. Currently, there is a paucity of methods to do conduct such an analysis. For the study, video observations of three different scenarios from 38 children with significant cognitive and motor developmental delays aged between 12 and 54 months, were used. Findings from the video observations served as the primary means for development of the coding scheme, which comprises three main categories - context, partner behavior, and individual behavior - and several subcategories. The coding scheme was used to document the early expressive communicative behavior of persons with significant cognitive and motor developmental delays in a detailed manner. This fine-grained information is necessary to differentiate children based on their communicative abilities, to monitor their communicative development longitudinally, and to inform person-centered communicative interventions.

Family-centered practices in home-based support for families with children with an intellectual disability: Judgments of parents and professionals.

BACKGROUND: The realization of the family-centered approach (FCA) in home-based support (HBS) for families with children with an intellectual disability (ID) in Flanders was investigated, and parents' and family workers' perspectives were compared. The relation between parents' educational level, the family worker's education, and his/her experience in HBS; and parents' and family workers' judgments on the realization of the FCA was considered. METHOD: Parents (N = 58 families) and family workers (N = 46) completed the helpgiving practices scale and the enabling practices scale. RESULTS: The FCA was largely present, parents rated its realization higher than family workers. Considering family workers' answers, parents' educational level appeared an important factor for parental autonomy. CONCLUSIONS: The study confirms recent research on the realization of the FCA. Including different perspectives, a nuanced view on the realization of the FCA was obtained. Further research on the concrete meaning, interpretation, and elaboration of the FCA is needed.

Comfort provided by parents versus strangers after eliciting stress in children with severe or profound intellectual disabilities: does it make a difference?

The relationships between children with severe or profound intellectual disabilities (ID) and their parents may fulfil attachment functions, such as regulating emotional responses to stress. This study examined the extent to which children with severe or profound ID differentiate between their parents and a stranger as a resource for stress-regulation. A home-based experimental paradigm was conducted and video-recorded in 38 families. Children (1-8 years) were exposed to four naturalistic stressors followed by comfort, randomly provided by the parents or the stranger. Emotional behaviour (arousal and valence) and the skin conductance level were simultaneously recorded. With regard to both emotional behaviour and skin conductance, children significantly differentiated between their parents as attachment figures and the stranger during stress and comfort, despite their impairments on various developmental domains. Behavioural observation and physiology show complementary manifestations of parent-child attachment in this population.

Communicative abilities in young children with a significant cognitive and motor developmental delay.

BACKGROUND: Children with a significant cognitive and motor developmental delay are pre-symbolic communicators. The primary aim of this study was to reveal the variability within the communicative functioning of this group of children in terms of communication level, the reasons to communicate and behavioural expressions. METHODS: Twenty-six children between 14 and 58 months with a significant cognitive and motor developmental delay were recruited. The Communication Matrix of Rowland (2011, Communication Disorders Quarterly, 32, 190) was used to integrate different sources of information on the children's communicative functioning. RESULTS: These children primarily communicated at the level of pre-intentional and intentional behaviour, aimed at refusing, obtaining and, to a lesser extent, social purposes. CONCLUSIONS: To develop or adapt early intervention strategies, and to monitor progress in communicative development, an even more nuanced view on these children's communicative utterances in terms of frequency, duration, idiosyncrasy and context relatedness is needed.

An investigation into the relationship between Quality of pantomime gestures and visuospatial skills.

While children with developmental language disorder or Williams syndrome appear to use hand gestures to compensate for specific cognitive and communicative difficulties, they have different cognitive strength-weakness profiles. Their semantic and visuospatial skills potentially affect gesture quality such as iconicity. The present study focuses on untangling the unique contribution of these skills in the quality of gestures. An explicit gesture elicitation task was presented to 25 participants with developmental language disorder between 7 and 10 years of age, 25 age-matched peers with typical development, and 14 participants with Williams Syndrome (8-23 years). They gestured pictures of objects without using speech (pantomime). The iconicity, semantic richness, and representation technique of the pantomimes were coded. Participants' semantic association and visuospatial skills were formally assessed. Iconicity was slightly lower in individuals with Williams syndrome, which seems related to their visuospatial deficit. While semantic saliency was similar across participant groups, small differences in representation technique were found. Partial correlations showed that visuospatial skills and semantic skills were instrumental in producing clear pantomimes. These findings indicate that clinicians aiming to enhance individuals' natural iconic gestures should consider achieved iconicity, particularly in individuals with low visuospatial skills.

How to improve the quality of life of elderly people with intellectual disability: A systematic literature review of support strategies.

BACKGROUND: The increased life expectancy of people with intellectual disability intensifies the need for age-specific support. Research on effects of support strategies on quality of life (QoL) of these people remains scattered. METHODS: A systematic search of peer-reviewed publications since 1995 was performed, with participants having intellectual disability and being aged ≥50 years. Studies include experimental, observational and exploratory designs, analysing links between support strategies and QoL outcomes. The present authors adopted a narrative approach. RESULTS: The present authors found 73 articles, assessed their quality, thematically categorized interventions into 12 themes, and listed them with their stated relationships to QoL. CONCLUSIONS: The studies indicated the importance of funding, provision and organization of services/personnel, education, and cooperation among different support systems. The provision of good housing or activities, support when these provisions change, provision of (mental) health care, dementia care and end-of-life care, life story work, future planning and support for (I)ADLs are crucial.

Exploring family activities and child engagement: A study on children with a significant cognitive and motor developmental delay.

BACKGROUND: Everyday activities are an important setting for stimulating child functioning, but are understudied in young children with a significant cognitive and motor developmental delay. Therefore, we aim to characterize their family activities in terms of diversity, frequency, child engagement and family member's presence, compared to typically developing children. METHODS: By asking a parent to fill out an adapted version of the Child Participation in Family Activities questionnaire, the activity pattern of 49 children within the study group and 45 children within the control group were assessed and compared. RESULTS: Children in the study group generally experience less diverse activities (with an additional lower frequency of out-of-home activities) and show lower engagement levels compared to typically developing children. CONCLUSIONS: Incorporating high levels of personal interaction, highly stimulating activities and adapted leisure activities into the daily activity pattern of children with multiple disabilities might be a pathway to increased engagement levels.

Young children with significant developmental delay differentiate home observed attachment behaviour towards their parents.

BACKGROUND: The hallmark of attachment is that contact, proximity and relief from stress are sought from specific individuals, laying important groundwork for healthy socioemotional functioning. This study investigated the extent to which differentiated attachment behaviour can be observed in young children with significant developmental delay (DD). METHOD: Video-taped observations of the parent-child and stranger-child interaction were conducted at home and complemented with questionnaires in 20 families with a child with significant DD (age 2-7 years with an average DD of 49 months). RESULTS: Children displayed more intense and persistent contact-seeking, contact-maintaining and resistant behaviour in the episodes with their parent compared to the episodes with the stranger. Parent-reported secure attachment behaviour was slightly more characteristic towards mother compared to father. CONCLUSIONS: Even children with significant DD develop differentiated attachment behaviour. Detailed observations may support parents in identifying the interactions that make the attachment relationship with their child special.

Beliefs and habits: staff experiences with key word signing in special schools and group residential homes.

Even though use of aided augmentative and alternative communication (AAC) by staff has been extensively researched, few studies relate to unaided AAC strategies such as key word signing (KWS). We explored the KWS views of two groups: direct support staff in group residential homes and teachers from special education secondary schools. We examined transcripts from individual semi-structured interviews with five direct support staff and five teachers using thematic analysis. Participants discussed consistency of KWS use and reasons for implementing KWS. Compared to direct support staff, teachers described more use of KWS throughout the day with more individuals with intellectual disability. Teachers discussed use of KWS to facilitate students' present and future interactions, while direct support staff primarily discussed immediate effects. Participants experienced KWS implementation as a learning process and aimed to turn the use of manual signs into a routine habit. This required considerable self-monitoring, and the effort that this continuous self-feedback required, combined with environmental factors, could hinder KWS implementation. These preliminary findings suggest that preservice KWS training and on-site KWS assistance may need to be enhanced.

Maintenance of key word signing in adults with intellectual disabilities: novel signed turns facilitated by partners' consistent input and sign imitation.

The aim of the present study was to examine the relationship between the use of key word signing (KWS) by support staff and by adults with intellectual disabilities (clients) who had experience with using KWS. Specifically, we explored whether these clients were more inclined to use KWS when support staff used KWS or imitated signs. One-to-one conversations between 24 clients and their support staff were filmed and transcribed. Partner turns were coded for communication mode (spoken or signed) and KWS response type (i.e., imitation, repetition, or new), while client turns were coded for communication mode and novelty (novel or non-novel). Using Cramer's V, strength of association was measured between each partner and subsequent client turn. Results indicated a moderate to strong association between partners' and clients' communication mode. In addition, partner turns containing newly introduced signs were associated with non-novel signed client turns, whereas sign imitations and repetitions by partners were more often followed by novel than non-novel signed client turns. These findings suggest that a balanced KWS input that includes new signed lexical items and sign imitations/repetitions may help to facilitate clients' KWS production and maintenance. This study was exploratory, and further research is needed to validate these results.

Middle Childhood Support-Seeking Behavior During Stress: Links With Self-Reported Attachment and Future Depressive Symptoms.

This study tested whether children's more anxious and avoidant attachment is linked to decreased support-seeking behavior toward their mother during stress in middle childhood, and whether children's decreased support-seeking behavior enhances the impact of experiencing life events on the increase of depressive symptoms 18 months later. Ninety-eight 8- to 12-year-old children filled out questionnaires assessing their level of anxious and avoidant attachment and depressive symptoms. Children's support-seeking behavior was observed through measuring the time children waited before calling for their mother's help while carrying out a stressful task. Results supported the hypothesis that more anxiously or avoidantly attached children waited longer before seeking maternal support. Moreover, waiting longer was related to increased depressive symptoms at follow-up in children who reported more experienced life events.

Joint attention behaviours in people with profound intellectual and multiple disabilities: the influence of the context.

BACKGROUND: In spite of the profound cognitive and physical problems, people with profound intellectual and multiple disabilities (PIMD) are able to develop joint attention behaviours (JAB) and benefit from positive interactions. AIMS: To investigate which context factors influence the JAB of people with PIMD. METHOD: Based on video recordings of 45 participants, JAB and context factors were analysed. RESULTS: An unstructured interaction situation produced the most responses of a person with PIMD, whereas a structured interaction situation produced the most initiatives. Furthermore, the familiarity of the partner and the familiarity of objects used in the interaction had no influence on the JAB. The sensitivity of the interaction partner was positively related to the presence of JAB. CONCLUSIONS: Interaction partners of people with PIMD should be aware of both the ability of people with PIMD to use JAB and the influence of different context factors on these JAB.

Peer Interactions among Children with Profound Intellectual and Multiple Disabilities during Group Activities.

BACKGROUND: Children with profound intellectual and multiple disabilities (PIMD) meet other children with PIMD in day care centres or schools. This study explores the peer-directed behaviours of children with PIMD, the peer interaction-influencing behaviour of the direct support workers and the children's positioning. METHOD: Group activities for children with PIMD initiated by a direct support worker were video-recorded. The behaviour and positioning of the children and the behaviour of the direct support workers were coded. RESULTS: Limited peer-directed behaviour of the children with PIMD and peer interaction-influencing behaviour of the direct support workers are observed. Weak associations were found between the positioning or peer interaction-influencing behaviours and the behaviour of children with PIMD. CONCLUSIONS: Children with PIMD show social interest in each other during group activities. More knowledge is needed to create an environment which facilitates peer-directed behaviours of persons with PIMD.
