Intentional communication acts expressed by children with severe disabilities in high-rate contexts

Turn-taking and communication modes of students and staff in group activities at non-inclusive schools for students with intellectual disability

Most students with intellectual and communicative disability who rely on augmentative and alternative communication (AAC) attend non-inclusive school settings. Little is known about turn-taking and the use of various communication modes in groups of students and staff in this context. Previous studies on single students with intellectual disability in various school settings have found that staff tend to dominate interactions and augmented communication modes are used more during structured than unstructured activities. The present study explored turn-taking contributions and communication modes in whole groups of students and staff in non-inclusive school settings in Sweden. Video observations of 33 students and 30 school staff were conducted in seven classrooms during one structured activity (circle time) and one unstructured activity (leisure time). Turn-taking contributions and communication modes were examined when comparing students and staff and when comparing the two activities. Findings revealed that staff dominated the interactions and augmented communication modes were used less during leisure time than circle time. Notably, aided augmented communication modes, particularly speech-output technologies, were used sparsely. Findings of this study highlight the importance of supporting staff members in applying partner strategies and incorporating augmented input, especially aided augmented input, across various group activities at school.

Changes in the early communicative behaviors of young children with significant cognitive and motor developmental delays in a two-year span

INTRODUCTION

This study examines longitudinal changes in communicative behavior of young children with significant cognitive and motor developmental delays (SDD) and determines their individual communicative trajectories. A second focus of this study is the relation of changes in communicative behavior with motor skills.

METHODS

Data consists of codes resulting from a self-developed coding scheme used on observations of 23 children in three different settings and responses on a questionnaire. First, group trends were determined to find out whether communication-related variables tend to significantly change over the course of two years. Furthermore, these findings were contrasted with the individual trajectories of the children. Next, the association of initial communicative skills and (the acquisition of) specific motor skills with the change in their communicative functioning was studied. Wilcoxon Signed Ranks and correlational analyses were used to answer the research questions.

RESULTS

Out of sixteen different variables related to communicative behavior, ten changed significantly over the course of two years. Children with more focus on prompt on the first datapoint showed a significantly larger increase of signs of functionality. Still, all children showed highly individual trajectories. Children with better motor skills on the first datapoint showed a significantly larger increase in communication rate.

CONCLUSIONS

Results show that if a myriad of detailed variables are taken into account children with significant cognitive and motor developmental disabilities do change regarding their communicative functioning, but that they tend to all show unique developmental trajectories. Children with stronger skills in some aspects of communication and motor functioning, can be considered advantaged regarding their communicative development.

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.

Effects of Wait Time when Communicating with Children who have Sensory and Additional Disabilities

Introduction

This study utilized wait-time procedures to determine if they are effective in helping children with deafblindness or multiple disabilities that include a visual impairment communicate in their home.

Methods

A single subject with an alternating treatment design was used for the study. Zero- to one-second wait time was utilized before prompting for a response during three baseline sessions. This was compared to 5-, 10-, and 15-second wait-time increments used during six intervention sessions. Three participants with visual impairments, developmental disabilities, and communication delays participated in the study. One of the participants was deafblind.

Results

All three participants responded twice as often during intervention phases as in baseline sessions. The results showed that 5-, 10-, and 15-second wait times were effective when reciprocally communicating with children who have multiple disabilities with a visual impairment or deafblindness.

Discussion

The findings of this study determined that wait time was effective and showed promising results for children with deafblindness or multiple disabilities. The study indicated that such children need time to process what is being asked in order to respond appropriately. Prompting quickly can frustrate the child with disabilities. Limitations of the study included heterogeneity and fragile medical condition of the participants, distractions, and the need for future research on the use of this technique.

Implications for practitioners

By utilizing at least five seconds of wait time, parents and educators may be able to see an increase in appropriate responses from the child. Wait-time interventions could increase opportunities for learning, social interaction, and communication, and are easily implemented with little to no training.

Evaluating an AAC training for special education teachers in Sri Lanka,a low- and middle-income country

A majority of people with disabilities live in low- and middle-income countries where communication services for individuals with complex communication needs are scarce. It is essential that communication partners of individuals who have complex communication needs receive training to support communication. To address this issue, the current study evaluated an augmentative and alternative communication training for special education teachers living in a low- and middle-income country, Sri Lanka. The training was based on four key practices identified when training in low- and middle-income countries: investigate learner needs, provide contextually relevant instructional content, use engaging instructional activities, and assess the impact of instructional activities. This investigation implemented an interrupted time-series design with nine teacher-student dyads. Special education teachers were taught to provide evocative communication opportunities. Following the training, all nine special education teachers significantly increased the number of evocative communication opportunities provided to students with complex communication needs. Additionally, all nine students with complex communication needs significantly increased their number of communication turns.

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.

The nature of peer-directed behaviours in children with profound intellectual and multiple disabilities and its relationship with social scaffolding behaviours of the direct support worker

BACKGROUND

The multiple and complex disabilities of persons with profound intellectual and multiple disabilities (PIMD) form a barrier for peer interactions and peer-directed behaviours. In this study, we further explore the nature of peer-directed behaviours in persons with PIMD and its relationship with social scaffolding behaviour of direct support workers (DSWs).

METHODS

Fourteen dyads of children with PIMD, who knew each other for at least 12 months, participated. They were sitting in close proximity while they were filmed with and without the presence of the DSW. Video recordings were coded continuously making use of observation schemes for the peer-directed behaviours of the children and the peer interaction influencing behaviours of the DSW.

RESULTS

Significantly more singular peer-directed behaviour (without DSW: 18.00%; with DSW: 3.81%) was observed than multiple peer-directed behaviour (without DSW: 4.01%; with DSW: 0.52%). The amount of time the singular and multiple peer-directed behaviours were observed was significantly lower in the presence of a DSW. When the DSW shows peer interaction influencing behaviour, it was mostly social scaffolding behaviour (2.17%). The conditional probability of observing social scaffolding behaviour in the 10 s following on singular peer-directed behaviour was 0.02 with a Yule's Q of 0.04 and following on multiple peer-directed behaviour 0.04 with a Yule's Q of 0.33.

CONCLUSION

The way in which peer interactions in children with PIMD are defined could have an impact on the amount of observed peer-directed behaviours and on the effect of the social scaffolding behaviours presented by DSW.

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.

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.

Speech and language therapists' approaches to communication intervention with children and adults with profound and multiple learning disability

BACKGROUND

People with profound intellectual and multiple disabilities (PMLD) have communication impairments as one defining characteristic.

AIMS

To explore speech and language therapists' (SLTs) decision making in communication interventions for people with PMLD, in terms of the intervention approaches used, the factors informing the decisions to use specific interventions and the extent to which the rationales underpinning these decisions related to the components of evidence based practice (EBP), namely empirical evidence, clinical experience and client/carer views and values.

METHODS & PROCEDURES

A questionnaire on communication assessment and intervention for people with PMLD was sent to SLTs in the UK to elicit information on: the communication intervention approaches they used; their rationales for their intervention choices; their use of published evidence to inform decision making.

OUTCOMES & RESULTS

Intensive interaction and objects of reference were the communication interventions most often used with people with PMLD, with some differences between children and adults evident. Rationales provided conformed somewhat to the EBP framework though extension of the existing framework and addition of practical and organizational considerations led to a revised typology of rationale for decision making. Rationales most frequently related to the empowerment, development and behavioural preferences of the person with PMLD.

CONCLUSIONS & IMPLICATIONS

Empirical research evidence was seldom mentioned by SLTs as informing intervention decision making leading to very diverse practice. There is a need for further research on the effectiveness of commonly used but under-evaluated interventions. There is also a need to alert SLTs to the evidence base supporting other approaches, particularly switch-based, cause and effect approaches.

Promoting Academic Achievement for Early Communicators of All Ages

A review of best practices and recent research efforts provide guidance for serving school-age early communicators with complex communication needs (CCN) and significant cognitive disabilities (SCD). Our aim as SLPs working with students with CCN and SCD is to support the development of intentional and symbolic communication abilities and implement augmentative and alternative communication (AAC) systems that provide the means for interaction with a range of partners for varied purposes on a myriad of topics. Consistent exposure to knowledgeable communication partners who respond in meaningful ways to expressive behaviors leads the way for learning to use symbolic forms of communication. It is through our instruction and aided language input across a range of contexts that our students with SCD learn and assign meaning to the symbolic representations we teach. The Common Core State Standards (CCSS) have heightened expectations about what students with SCD should know and be able to do and offer contexts that emphasize communication as an integral part of learning. Meeting these expectations through active participation and interaction in all learning activities requires reliable access to systems of communication that support ongoing development of abilities as a speaker, listener, reader, and writer.

Temporal analysis of attentional processes in spontaneous interactions between people with profound intellectual and multiple disabilities and their support workers

BACKGROUND

Few studies examined joint attention in interactions with people with profound intellectual and multiple disabilities (PIMD), although being an important component of high-quality interaction. The purpose of this study is to describe initiating joint attention behaviour from people with PIMD and their support workers as well as the sequential relationship between initiating joint attention behaviour and attention episodes in spontaneous interactions.

METHOD

Video observations of 28 support worker-client dyads were coded using partial interval coding.

RESULTS

Results show much variation across persons and dyads. Within the support worker-client dyad, there is not much joint attention but shared attention is frequently occurring. In general, people with PIMD are directing the attention of their interaction partner at low rates. The support workers are frequently directing the attention of the clients towards a topic of interest but not often through the tactile modality. The occurrence of an attention episode cannot be predicted on the basis of preceding initiating joint attention behaviour of the interaction partners.

CONCLUSION

This study presents directions for future research and implications for practice. It may increase support workers' knowledge of their own contributions, strengths and weaknesses in directing and maintaining attention within interactions with people with PIMD.

Examination of the communication interface between students with severe to profound and multiple intellectual disability and educational staff during structured teaching sessions

BACKGROUND

Individuals with severe to profound and multiple intellectual disability (S-PMID) tend to function at the earlier stages of communication development. Variable and highly individual means of communicating may present challenges to the adults providing support in everyday life. The current study aimed to examine the communication interface between students with S-PMID and educational staff.

METHOD

An in-depth, observational study of dyadic interaction in a class within the secondary part of a special school was conducted. The designated educational level was Key Stage 3 under the National Curriculum of England, which is typically for children from age 11 to 14 years attending a state school. There were four student-teacher dyads in the class. The students had multiple impairments with severely limited communication skills. Video capture of dyadic interaction was conducted during five English lessons and sampled to 2.5 min per dyad per lesson. The video footage was transcribed into standard orthography, detailing the vocal and non-vocal aspects. A coding framework guided by the principles of structural-functional linguistics was used to determine the nature of dyadic interaction, comprising linguistic moves, functions and communicative modalities. The relative contributions of student and teacher to the interaction were examined.

RESULTS

Significant differences were found between the students and educational staff on the majority of the measures. The teachers dominated the interaction, occupying significantly more turns than the students. Teacher turns contained significantly more initiations and follow-up moves than the students, who used more response moves. Teacher communication mainly served the functions of requesting and information giving. Feedback and scripted functions were also significantly greater among teacher turns, with only limited occurrence among the students. Self- or shared-expression was greatest among the students. The modalities of speech, touch, singing and objects were used by the teachers for the purpose of communication, whereas vocalisation and gesture were used by the students.

CONCLUSIONS

Despite differences in the availability of communication skills, both student and teacher were able to make their respective contributions to the interaction during classroom activity. Features of the student-teacher interface retained critical features seen in studies of more able individuals with intellectual disability. Scaffolding provided by teachers appears to be relevant to the communicative contributions of individuals functioning at the earliest stages of communication. The coding framework based on structural-functional linguistics provides some new potential for examining and enhancing the communication interface between individuals with S-PMID and the people who support them.

Attentional processes in interactions between people with profound intellectual and multiple disabilities and direct support staff

Few studies have examined joint attention in interactions with persons with profound intellectual and multiple disabilities (PIMD), despite its important role in high-quality interaction. The purpose of this study is to describe the attention-directing behaviours of persons with PIMD and their direct support staff and the attention episodes resulting from their interactions, and to understand how these variables relate to each other. Video observations of 17 staff-client dyads were coded using partial interval recording. The results showed considerable variation across individuals and dyads. In general, persons with PIMD directed the attention of staff members infrequently. The staff members frequently directed their clients' attention towards a topic of interest but did not often use the tactile modality. Within the staff-client dyad, there was not much joint attention; however, shared attention episodes occurred frequently. Shared attention and joint attention are strongly correlated. A negative correlation was found between clients not using attention-directing behaviours and staff members using tactile methods to direct the attention, and joint attention episodes. This study presents both directions for future research and practical implications.
