Decision-making in communication aid recommendations in the UK: cultural and contextual influencers

Assessment of Cognition and Language Using Alternative Response Modalities

Assessing cognition and language using standardized tests is challenging when the individual has severe speech and motor impairments. Tests with a multiple-choice format may be adapted without compromising standardization using alternative response modes like partner assisted scanning (PAS) and eye-pointing (EP). Standardization of such assessment is little researched. The study investigates the (a) reliability of, (b) transparency of, and (c) adherence to assessment protocols using PAS and EP. The participants were students from special needs education and speech and language therapy, who worked in dyads (n = 39). Two observers recorded a number of errors made in protocol delivery, independently of each other. The dyads made between 0 and 81.5 errors. Number of errors was not related to response mode, t(38) = -0.21, p = .839. The observers were in high agreement, with an intraclass correlation coefficient of .97, p < .001. The study suggests that assessing language involving alternative modes of responding can be successfully taught to novice practitioners.

Voices from the field: exploring service providers' insights into service delivery and AAC use in Canada

Use of augmentative and alternative communication (AAC) often relies on the involvement of AAC service providers; however little is known about how AAC services are delivered across Canada. This study aimed to explore AAC service provision and factors influencing use of AAC from the perspectives of service providers across Canada who are involved in providing and/or supporting use of AAC systems. The 22 participants from nine (of the 10) provinces participated in online focus groups. Participants were speech-language pathologists, occupational therapists, communicative disorders assistants, and a teacher. Transcripts of the audio recordings were analyzed using reflexive thematic analysis. Four themes were generated that reflect service-related factors contributing to the use of AAC in Canada: Support of Organizational Structures, Concordant Relationships and Goals, Making the Right Decisions, and Influence of Knowledge and Attitudes. These themes highlight how government systems, key stakeholders, assessment practices, and knowledge of AAC influence service provision and use of AAC. Voices from across Canada highlighted shared experiences of services providers as well as revealed variability in service delivery processes. The findings bring to attention a need for further research and development of service provision guidelines to support consistency, quality in practice, and equity in AAC services.

Use of eye-gaze technology feedback by assistive technology professionals: findings from a thematic analysis

Purpose: Eye-gaze technology offers professionals a range of feedback tools, but it is not well understood how these are used to support decision-making or how professionals understand their purpose and function. This paper explores how professionals use a variety of feedback tools and provides commentary on their current use and ideas for future tool development.Methods and Materials: The study adopted a focus group methodology with two groups of professional participants: those involved in the assessment and provision of eye-gaze technology (n = 6) and those who interact with individuals using eye-gaze technology on an ongoing basis (n = 5). Template analysis was used to provide qualitative insight into the research questions.Results: Professionals highlighted several issues with existing tools and gave suggestions on how these could be made better. It is generally felt that existing tools highlight the existence of problems but offer little in the way of solutions or suggestions. Some differences of opinion related to professional perspective were highlighted. Questions about automating certain processes were raised by both groups.Conclusions: Discussion highlighted the need for different levels of feedback for users and professionals. Professionals agreed that current tools are useful to identify problems but do not offer insight into potential solutions. Some tools are being used to draw inferences about vision and cognition which are not supported by existing literature. New tools may be needed to better meet the needs of professionals and an increased understanding of how existing tools function may support such development.

A qualitative evidence synthesis of the experiences and perspectives of communicating using augmentative and alternative communication (AAC)

PURPOSE

This paper presents a review of the existing qualitative research literature concerning people's experience of communicating using augmentative and alternative communication (AAC). The aims of conducting this review were to find out more about the values and outcomes that are important to people about the AAC they use to support their communication. This review was conducted to provide a deeper understanding of these experiences to inform the development of a patient-reported outcome measure (PROM).

MATERIALS AND METHODS

A qualitative evidence synthesis of existing qualitative research literature was undertaken to explore and appraise current knowledge about the experiences of people who use AAC.

RESULTS

From 115 qualitative research reports 19 papers were identified that responded directly to the research question and aims of the review. Data were identified that could be organized within an a priori framework consisting of the constructs of values, outcomes, and context.

CONCLUSION

The review has resulted in a deeper, analytical understanding of the experiences of people who require AAC. The results indicate a set of concepts that can be used to inform the development of a PROM. A PROM can be used to assist clinicians and researchers to better understand the perspectives of people who require AAC and evaluate interventions. The results also encourage professionals to reconsider the terminology and methods used when working alongside people who require AAC and to reflect on the multidimensional factors that influence people's experience of communication.

Models and frameworks for guiding assessment for aided Augmentative and Alternative communication (AAC): a scoping review

BACKGROUND

Augmentative and Alternative Communication (AAC) supports individuals with complex communication needs. Conceptual models and frameworks exist to evaluate, implement, and assess the needs of persons with communication disabilities, however, it is unknown which models were grounded in previous evidence-based research.

OBJECTIVE

What are the models and frameworks grounded in empirical or conceptual research that enable communication outcomes for persons who require aided AAC systems?

ELIGIBILITY CRITERIA

The study had to be the original publication of a defined model or framework that included aided AAC and the model had to be developed through research, either conceptual or empirical.

SOURCES OF EVIDENCE

Eleven databases were searched using terms associated with AAC devices, conceptual models, and assessment processes. Fifteen articles presenting 14 independent assessment models were included.

CHARTING METHODS

A custom data extraction form included model development using existing models and research evidence, the model's input parameters, and explicit outcome measures.

RESULTS

Four models were specific to AAC while ten models were general evaluations for assistive technology systems. Models used a variety of descriptive traits during assessment including: person, technology, environment and context, and the activity or task. Only nine models sought to iteratively assess the client. Eleven of the models identified the inclusion of members from different disciplines in the assessment process.

CONCLUSIONS

There is a need to standardize descriptive traits: personal abilities, environmental characteristics, potential assistive technology, and contextual factors. Models should include teams of different disciplines to provide holistic assessments. Models should include outcomes and include iterative solutions.

Interprofessional clinical decision-making process in health: A scoping review

AIMS

To describe the key elements of the interprofessional decision-making process in health, based on published scientific studies. To describe the authors, reviews and subject matter of those publications.

DESIGN

Scoping review of the literature.

DATA SOURCES

MEDLINE, APA Psycinfo OpenGrey, Lissa and Cochrane databases were searched in December 2019 and January 2023.

REVIEW METHODS

References were considered eligible if they (i) were written in French or English, (ii) concerned health, (iii) studied a clinical decision-making process, (iv) were performed in an interprofessional context. 'PRISMA-scoping review' guidelines were respected. The eligible studies were analysed and classified by an inductive approach RESULTS: We identified 1429 sources of information, 145 of which were retained for the analysis. Based on these studies, we identified five key elements of interprofessional decision-making in health. The process was found to be influenced by group dynamics, the available information and consideration of the unique characteristics of the patient. An organizational framework and specific training favoured improvements in the process.

CONCLUSION

Decision-making can be based on a willingness of the healthcare organization to promote models based on more shared leadership and to work on professional roles and values. It also requires healthcare professionals trained in the entire continuum of collaborative practices, to meet the unique needs of each patient. Finally, it appears essential to favour the sharing of multiple sources of accessible and structured information. Tools for knowledge formalization should help to optimize interprofessional decision-making in health.

IMPACT

The quality of a team decision-making is critical to the quality of care. Interprofessional decision-making can be structured and improved through different levels of action. These improvements could benefit to patients and healthcare professionals in every settings of care involving care collaboration.

IMPACT STATEMENT

Interprofessional decision-making in health is an essential lever of quality of care, especially for the most complex patients which are a contemporary challenge. This scoping review article offers a synthesis of a large corpus of data published to date about the interprofessional clinical decision-making process in healthcare. It has the potential to provide a global vision, practical data and a list of references to facilitate the work of healthcare teams, organizations and teachers ready to initiate a change.

Provision of augmentative and alternative communication interventions to Norwegian preschool children with cerebral palsy: are the right children receiving interventions?

Preschool children with cerebral palsy (CP) with no or unintelligible speech need augmentative and alternative communication (AAC), but not all children needing AAC have access to it. This study describes the use and perceived benefit of AAC and explores factors associated with receiving AAC interventions. Using a cross-sectional design, we combined parent-reported data with data from the Norwegian Quality and Surveillance Registry for Cerebral Palsy (NorCP). Communication, speech and hand function was classified according to the Communication Function Classification System (CFCS), Viking Speech Scale (VSS), and Manual Ability Classification System (MACS), accordingly. The need for AAC was defined as Levels III-V on the CFCS, without simultaneous classification at VSS Level I, and/or Levels III-IV on VSS. Parents reported on child- and family-directed AAC interventions using the Habilitation Services Questionnaire. Of the 95 children (42 females) with CP (M = 39.4 months, SD = 10.3), 14 had communication aids. Of the 35 children (31.4%) defined as needing AAC, 11 had been provided with communication aids. Parents of children with a communication aid reported satisfaction with and frequent use of the aid. Children at MACS Level III-V (OR = 3.4, p = .02) or with epilepsy (OR = 8.9, p < .01) were most likely to have received an AAC intervention. The low proportion of children receiving communication aids indicates an unmet need for AAC interventions among preschool children with CP.

Something for everybody? Assessing the suitability of AAC systems for children using stated preference methods

Little is known about what features of AAC systems are regarded by AAC professionals as more suitable for children with different characteristics. A survey was conducted in which participants rated the suitability of hypothetical AAC systems on a Likert scale from 1 (very unsuitable) to 7 (very suitable) alongside a discrete choice experiment. The survey was administered online to 155 AAC professionals in the United Kingdom of Great Britain and Northern Ireland. Statistical modeling was used to estimate how suitable 274 hypothetical AAC systems were for each of 36 child vignettes. The proportion of AAC systems rated at least 5 out of 7 for suitability varied from 51.1% to 98.5% for different child vignettes. Only 12 out of 36 child vignettes had any AAC systems rated at least 6 out of 7 for suitability. The features of the most suitable AAC system depended on the characteristics of the child vignette. The results show that, while every child vignette had several systems that had a good suitability rating, there were variations, that could potentially lead to inequalities in provision.

Attributes of communication aids as described by those supporting children and young people with AAC

BACKGROUND

Those supporting children and young people who use augmentative and alternative communication (AAC) contribute to ongoing complex decision-making about communication aid selection and support. Little is known about how these decisions are made in practice and how attributes of the communication aid are described or considered.

AIMS

To understand how communication aid attributes were described by those involved in AAC recommendations and support for children and young people, and how these attributes were described as impacting on AAC use.

METHODS & PROCEDURES

A secondary qualitative analysis was completed of interview and focus group data from 91 participants involved in the support of 22 children and young people. Attributes of communication aids described by participants were extracted as themes and this paper reports a descriptive summary of the identified software (non-hardware) attributes.

MAIN CONTRIBUTION

Decisions were described in terms of comparisons between commercially available pre-existing vocabulary packages. Attributes related to vocabulary, graphic representation, consistency and intuitiveness of design, and ease of editing were identified. Developmental staging of vocabularies, core and fringe vocabulary, and vocabulary personalization were attributes that were described as being explicitly considered in decisions. The potential impact of graphic symbol choice did not seem to be considered strongly. The physical and social environment was described as the predominant factor driving the choice of a number of attributes.

CONCLUSIONS & IMPLICATIONS

Specific attributes that appear to be established in decision-making in these data have limited empirical research literature. Terms used in the literature to describe communication aid attributes were not observed in these data. Practice-based evidence does not appear to be supported by the available research literature and these findings highlight several areas where empirical research is needed in order to provide a robust basis for practice.

WHAT THIS PAPER ADDS

What is already known on the subject Communication aid attributes are viewed as a key consideration by practitioners and family members in AAC decision-making; however, there are few empirical studies investigating language and communication attributes of communication aids. It is important to understand how those involved in AAC recommendations and support view communication aid attributes and the impact different attributes have. What this paper adds to existing knowledge This study provides a picture of how communication aids are described by practitioners and family members involved in AAC support of children and young people. A range of attributes is identified from the analysis of these qualitative data as well as information about how participants perceive these attributes as informing decisions. What are the potential or actual clinical implications of this work? This study provides a basis on which practitioners and others involved in AAC support for children and young people can review and reflect on their own practice and so improve the outcomes of AAC decisions. The study provides a list of attributes that appear to be considered in practice and so also provides a resource for researchers looking to ensure there is a strong empirical basis for AAC decisions.

Measuring impact of augmentative and alternative communication interventions: adapting the family impact of assistive technology scale for augmentative and alternative communication (FIATS-AAC-No) for use in Norway

Individuals who require augmentative and alternative communication (AAC) comprise a heterogeneous group, but all need follow-up to assure the appropriateness of implemented interventions. To enable this, outcome measures such as the Family Impact of Assistive Technology Scale for Augmentative and Alternative Communication (FIATS-AAC) may be used. However, instrument must be adapted to the language and culture in which they are to be used. The aim of the study was to therefore to explore the suitability of the Norwegian short-form version (FIATS-AAC-No) by investigating the reliability, validity, and perceived clinical usefulness. The study utilized a mixed-method design, including an online survey and two small group interviews. In total, 47 parents responded to the online survey. The online survey was comprised of three questionnaires, where FIATS-AAC-No was one of the questionnaires. Two group interviews, with two parents and two clinicians, were conducted. Findings show satisfactorily reliability, construct validity and content validity. The interviews revealed a need for specification of key concepts, that there are challenges involved in being parents of a child needing AAC, and that completing questionnaires was perceived as stressful by many parents. The clinicians viewed the FIATS-AAC-No as a potentially useful clinical tool and expressed that it brought to attention the need for follow-up parents have.

Aided communication, mind understanding and co-construction of meaning

Mind understanding allows for the adaptation of expressive language to a listener and is a core element when communicating new information to a communication partner. There is limited knowledge about the relationship between aided language and mind understanding. This study investigates this relationship using a communication task. The participants were 71 aided communicators using graphic symbols or spelling for expression (38/33 girls/boys) and a reference group of 40 speaking children (21/19 girls/boys), aged 5;0-15;11 years. The task was to describe, but not name, drawings to a communication partner. The partner could not see the drawing and had to infer what was depicted from the child's explanation. Dyads with aided communicators solved fewer items than reference dyads (64% vs 93%). The aided spellers presented more precise details than the symbol users (46% vs 38%). In the aided group, number of correct items correlated with verbal comprehension and age.

Attribute Selection for a Discrete Choice Experiment Incorporating a Best-Worst Scaling Survey

OBJECTIVES

Although literature exists on using qualitative methods to generate potential attributes for a discrete choice experiment (DCE), there is little on selecting which attributes to include. We present a case study in which a best-worst scaling case 1 (BWS-1) survey was used to guide attribute selection for a DCE. The case study's context was the decision making of professionals around the choice of augmentative and alternative communication (AAC) systems for children with limited natural speech.

METHODS

BWS-1 survey attributes were generated from literature reviews and focus groups. DCE attributes were selected from BWS-1 attributes. The selection criteria were: include mostly important attributes; create coherent descriptions of children and AAC systems; address the project's research aims; have an appropriate respondent burden. Attributes' importance was judged using BWS-1 relative importance scores.

RESULTS

The BWS-1 survey included 19 child and 18 AAC device/system attributes and was administered to N = 93 AAC professionals. Four child and five device/system attributes were selected for the DCE, administered to N = 155 AAC professionals.

CONCLUSIONS

In this case study BWS-1 results were useful in DCE attribute selection. Four recommendations are made for future studies: define selection criteria for DCE attributes a priori; consider the impact participant's perspective will have on BWS-1 and DCE results; clearly define key terminology at the start of the study and refine it as the study progresses to reflect interim findings; BWS will be useful when there is little existing stated preference work on a topic and/or qualitative work is difficult.

The decision-making process in recommending electronic communication aids for children and young people who are non-speaking: the I-ASC mixed-methods study

Background

This project [Identifying Appropriate Symbol Communication (I-ASC)] explored UK decision-making practices related to communication aid recommendations for children and young people who are non-speaking. Research evidence related to communication aid decision-making is limited. The research aims were to increase understanding of influencers on the decision-making process in recommending electronic communication aids, and to develop guidance tools to support decision-making. An additional, post hoc aim was to evaluate the public involvement contribution to the I-ASC project. The research focused on the identification of attributes and characteristics that professionals, family members and those who use communication aids considered important in the recommendation process. Findings informed the development of guidance resources. The evaluation of public involvement focused on what could be learned from a nationally funded project with involvement from public contributors typically regarded as hard to include.

Methodology

For the clinical decision-making component, the methodological investigation adopted a three-tier approach with three systematic reviews, a qualitative exploration of stakeholder perspectives through focus groups and interviews, and a quantitative investigation surveying professionals’ perspectives. The public involvement evaluation adopted a mixed-methods approach. A total of 354 participants contributed to the decision-making data set, including professionals, family members, and children, young people and adults who use communication aids; 22 participants contributed to the public involvement evaluation. The literature review process followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Thematic analysis and framework approach supported the analysis of qualitative data. Two stated preference surveys, a best–worst scaling and a discrete choice experiment, allowed the relative importance of factors in decision-making to be determined. Analysis was grounded in random utility theory.

Public involvement

Two public involvement co-researchers, an adult using a symbol communication aid and a parent of a communication aid user, were core members of the research team. The I-ASC public involvement resulted in an additional award to evaluate the impact of public involvement across the project.

Results

Factors influencing decision-making are not always under the control of the decision-makers, for example professional knowledge, referral criteria and service structure. Findings suggest that real clinical decisions contrast with hypothetical decisions. Survey responses indicated that children’s physical characteristics are less important than their language, communication and learning abilities; however, during real-time decision-making, the opposite appeared to be true, with access needs featuring most prominently. In contrast to professionals’ decisions, users and family members prioritise differing aesthetic attributes of communication aids. Time allocated to system learning remains underspecified. The research informed the development of decision-making guidance tools (https://iasc.mmu.ac.uk/; accessed 8 June 2020). A public involvement evaluation suggests that successful public involvement of individuals with disabilities requires significant resources that include staff time, training and personal support (https://iasc.mmu.ac.uk/publicinvolvement; accessed 8 June 2020).

Future work

Further research is needed in the areas of language assessment, communication aid attributes, types of decision-making episodes and service user perspectives. These data highlight the need for mechanisms that enable public involvement co-researchers to be paid for their contributions to research bid preparation.

Limitations

Individuals who benefit from communication aids are a heterogeneous group. We cannot guarantee that this study has captured all relevant components of decision-making.

Finding the best fit: examining the decision-making of augmentative and alternative communication professionals in the UK using a discrete choice experiment

OBJECTIVES

Many children with varied disabilities, for example, cerebral palsy, autism, can benefit from augmentative and alternative communication (AAC) systems. However, little is known about professionals' decision-making when recommending symbol based AAC systems for children. This study examines AAC professionals' preferences for attributes of AAC systems and how they interact with child characteristics.

DESIGN

AAC professionals answered a discrete choice experiment survey with AAC system and child-related attributes, where participants chose an AAC system for a child vignette.

SETTING

The survey was administered online in the UK.

PARTICIPANTS

155 UK-based AAC professionals were recruited between 20 October 2017 and 4 March 2018.

OUTCOMES

The study outcomes were the preferences of AAC professionals' as quantified using a mixed logit model, with model selection performed using a step-wise procedure and the Bayesian Information Criterion.

RESULTS

Significant differences were observed in preferences for AAC system attributes, and large interactions were seen between child attributes included in the child vignettes, for example, participants made more ambitious choices for children who were motivated to communicate using AAC, and predicted to progress in skills and abilities. These characteristics were perceived as relatively more important than language ability and previous AAC experience.

CONCLUSIONS

AAC professionals make trade-offs between attributes of AAC systems, and these trade-offs change depending on the characteristics of the child for whom the system is being provided.
