Abstract
BACKGROUND:
Talking Mats™ is a framework developed to support communication with communication vulnerable people.
OBJECTIVE:
The objective was twofold: to provide an overview of the objectives, target groups and settings for which Talking Mats has been used (Part 1), and an overview of empirical scientific knowledge on the use of Talking Mats (Part 2).
METHODS:
In this scoping review scientific and grey literature was searched in PubMed, Cinahl, Psycinfo, Google, and Google Scholar. Articles that described characteristics of Talking Mats or its use were included. For Part 2, additional selection criteria were applied to focus on empirical scientific knowledge.
RESULTS:
The search yielded 73 publications in Part 1, 12 of which were included in Part 2. Talking Mats was used for functional objectives (e.g. goal setting) and to improve communication and involvement. Part 2 showed that Talking Mats had positive influences on technical communication, effectiveness of conversations, and involvement and decision making in conversations. However, the level of research evidence is limited.
CONCLUSIONS:
Talking Mats can be used to support conversations between professionals and communication vulnerable people. More research is needed to study the views of people who are communication vulnerable and to study the effects of Talking Mats.

Introduction
Effective communication is essential in health-care [3, 4]. However, conversations between communication vulnerable people and professionals are problematic, and the communicative difficulties of communication vulnerable people lead to major challenges in achieving self-advocacy and participation in healthcare decision making [5, 6]. Different definitions of communication vulnerable people have been proposed in the literature [8, 9]. We define them as those who struggle to communicate in a particular environment due to a medical condition. They experience difficulties in expressing their needs and/or in understanding information. Communication may be their primary disability, or their communication issues may be secondary to another disability. Limitations in any of the several areas of functioning can lead to someone being classified as communication vulnerable; for example, those with sensory, emotional, physical and cognitive difficulties [12].
Augmentative and alternative communication (AAC) tools can enable communication vulnerable people to express themselves and understand others, supporting self-advocacy. Such tools can also support professionals in understanding clients and enabling a partnership. This paper uses the broad definition of AAC by Clarke and Bloch [13], which incorporates different forms of AAC: formal communication aid systems (e.g. voice output communication aids), conventional semiotic systems (e.g. handwriting), as well as unaided resources (e.g. gesture) and commonplace objects (e.g. maps or letters).

Central topic symbol: The two persons having the conversation decide on a topic they want to talk about and place a symbol representing this topic at the bottom of the mat (for example, “activities you want to learn”). Option symbols: A set of option symbols related to the central topic is available (for example, “cooking”, “gardening”, and “biking”). The professional/caregiver presents option symbols one by one to the person who is communication vulnerable asking them how they feel or think about this option. Top scale symbols: The top scale symbols indicate the person’s feeling or opinion (for example, “positive”, “don’t know”, and “negative”). The communication vulnerable person can indicate their feelings or opinions about each option by placing the option symbol under the top scale. The professional/caregiver then asks questions to confirm this placement. The person who is communication vulnerable is always meant to be in control by indicating the placement of the symbols through verbal cues, pointing, or eye movement [15]. Visual summary: The professional/caregiver recapitulates the discussion and asks for more confirmation regarding the feelings/opinions expressed by the person. The mat presents a visual summary of the conversation (the mats are often photographed at the end of the conversation to preserve the content of the conversation) [16].
Talking Mats has been variously characterised as a low-technology tool [17], a visual framework [18], a procedure [14], a technique [19], a resource [20], or a method [21]. It has been used with different target groups, including people with dementia but also children. The literature is also inconsistent about the objectives for which one should use Talking Mats, for example for a casual conversation or for therapy goal setting [10, 11, 22]. Furthermore, there is no review available about the evidence for the effects of Talking Mats on different target groups. While Talking Mats seems to be used widely in the UK, an overview of its objectives, the target groups and settings for which it can be used, and its effectiveness is lacking.
Talking Mats is a different form of AAC than conventional AAC tools, as it both uses visualisation and provides a structure for a conversation. Studying the characteristics and use of Talking Mats and evidence for its effectiveness is therefore valuable for both research into AAC and for professionals and clients in healthcare. An overview of such knowledge about Talking Mats is needed to provide healthcare professionals with information about whether, when, and how they can use Talking Mats. The purpose of this scoping review is twofold: to provide an overview of the objectives, settings, and target groups in which Talking Mats has been used (Part 1), and an overview of the empirical scientific knowledge about the use of Talking Mats (Part 2).
This review was guided by the methodological framework for scoping reviews by Arksey and O’Malley [23]. Scoping reviews are suitable for studying the current state of knowledge on a topic, in order to comprehensively and systematically map the relevant literature, and identify key concepts and gaps in research [24]. The present literature review included two parts:
Part 1: An overview of the objectives, settings and target groups for which Talking Mats has been used, for which we included peer reviewed and grey literature. Part 2: An overview of empirical scientific knowledge about the use of Talking Mats within the objectives identified in Part 1. For this part, only peer-reviewed scientific literature was included.
The methods used in this scoping review are described below according to the stages of the Arksey and O’Malley framework, making a distinction between Parts 1 and 2.
A combination of search methods was used, including (a) the scientific databases PubMed, Cinahl, and Psychinfo, (b) the electronic search engine Google (including Google Scholar), (c) a publication list on the “Talking Mats Limited” website (the organisation that developed Talking Mats) [25]. The search term “Talking Mats” was used, restricted to title and abstract in the scientific databases, and as a free text word combination in Google (and Google Scholar). The search was restricted to materials published in English, Dutch, and German (the foreign languages with which the researchers are familiar) and published between 1998 and 2016 (Talking Mats appeared in the literature for the first time in 1998). The search using Google and Google Scholar was continued until saturation (no new articles after 100 hits). Duplicates were immediately ignored. The search was used for both Parts 1 and 2, and was completed in December 2016.
Study selection
During the study selection for Part 1, one researcher (SS) identified publications in which Talking Mats was mentioned in the title or abstract. The selected articles were then read and screened independently at full-text level by two researchers (SS and RD). Full-text articles were included if characteristics of Talking Mats were described, and/or if Talking Mats was used as an intervention in a study. Articles were excluded at full-text level if Talking Mats was merely mentioned, without being described, used, or studied. Due to the broad scope of Part 1, we imposed no restrictions on research type during the selection phases. After the inclusion of full texts, the researchers screened the reference lists of the selected articles for additional relevant publications. When necessary, two other researchers (AB & LD) were involved in the consensus process during the selection.
To focus specifically on scientific literature in Part 2, additional selection criteria were applied to the full-text publications included in Part 1. These selection criteria were: publication in a peer-reviewed journal, empirical study, and evaluation of the use of Talking Mats described in the study aims. The researchers used no restriction for research type, as scoping reviews are suitable for studying broad topics, and the inclusion of information in scoping reviews is not limited by the methodological quality of the research [23, 24]. Two researchers (SS, RD) independently performed the selection process, and differences of opinion were discussed until consensus was reached. When necessary, two other researchers (AB and LD) were involved in the consensus process.
Charting the data and collating, summarising and reporting the results
For Part 1, one researcher (SS) charted the data by reading and extracting descriptive data (i.e. year, author, country, target group, setting). Thereafter, an analysis focussing on the objectives of Talking Mats was performed by two researchers (SS, RD), following the principles of conventional content analysis [26]. First, text related to the objectives of the use of Talking Mats was highlighted in the publications. Second, these text fragments were given codes describing the type of objective they described. Third, these codes were arranged in overarching themes relating to the objectives of Talking Mats.
For Part 2, we extracted from each publication the author, year, country, aim of the study, participants and setting, target population and settings, objectives of Talking Mats, methods, and results. The results of the studies were then described, linked to the objectives of Talking Mats identified in Part 1. Furthermore, an overview was made of quality-related elements that had (+) or had not (-) been included in the publications. To achieve this we used lists based on the Critical Appraisal Skills Programme’s (CASP) tool [27, 28]. For mixed methods studies, both lists were used. One researcher (SS) applied these lists, and checked unclear cases with a second researcher (RD).
About Talking Mats
Talking Mats is a commercially available tool. It was originally developed by a group of speech and language pathology researchers to support people with cerebral palsy in the UK [29]. Based on positive experiences, it has since also been used in research and practice for many different target groups [30, 31]. The literature indicates that Talking Mats provides a structure in which topics/options are broken down into small units or chunks. Such a structure can enable a person to consider topics or options in relation to each other, focusing solely on the essential words/topics. This could also reduce cognitive load, help people process concepts more easily, reduce distractibility, and reduce memory demands [5, 11, 14, 32]. Talking Mats can be applied to discuss a specific topic, and is intended to be a supplement to a person’s individual communication skills and strategies [11].
Talking Mats has been described as a flexible communication framework, which should be used as a dynamic process that changes and reflects the person’s opinions at a specific time [33]. According to published descriptions, Talking Mats does not replace verbal, non-verbal, or other AAC-supported communication, but aims to support these communication modes in conversations by using a picture-based framework [21]. The literature indicates that Talking Mats can encourage a person to use different channels for communication: auditory (talking about views), as well as tactile (placing symbols on a mat) and visual (symbols for the theme, the options, and choices) [32]. The main feature of Talking Mats is that it visualises views (feelings, opinions) and choices in a conversation, also described as “building a picture of your views” [14]. A visual summary of the choices made as a result of the conversation is then displayed on the mat [16].
Results
Seventy-three articles were included in Part 1. After the additional selection criteria had been applied, 12 publications were included in Part 2. See Fig. 2 for a detailed summary of the abstract, full text, and inclusion numbers.
Number of studies included in the review during each phase.
Part 1 included publications from several countries: the UK (62 publications), Sweden (4 publications), South Africa (4 publications), Norway (1 publication), Malta (1 publication), and the Netherlands (1 publication). Included were peer-reviewed journal articles, research reports, book chapters, website reports, and conference abstracts. The objectives for which Talking Mats has been used, as well as an overview of settings and target groups are described below. A full overview of the details of the included articles can be found in Table 1.
Objectives
Three main themes emerged regarding the objectives of using Talking Mats: facilitating communication, facilitating involvement, and functional use. Figure 3.1.2 provides an overview of these themes and subthemes.
Facilitating communication. Within the theme of “facilitating communication”, the following subthemes were identified: facilitating expression, facilitating interaction, and facilitating thinking and understanding by structuring conversations into small units [5, 21, 34]. The subtheme of facilitating expression included expressing opinions, thoughts, or feelings [5, 21, 34].
Facilitating involvement. The “facilitating involvement” theme included facilitating involvement in interactions with individuals or groups, and facilitating involvement in decision-making [33, 35, 36].
Functional use of Talking Mats. Six subthemes were identified with regard to “functional use of Talking Mats”:
Goal setting: enabling people to identify, set, and review their own goals [37]. Enabling people to make activity choices [30, 38], including exploring which activities people want to do on a daily basis [30, 38]. Supporting people’s participation in research and projects [39, 40]. For example, Talking Mats could support the process of obtaining consent for research. Talking Mats could also support an interview procedure or project meeting, or make standard questionnaire items accessible to communication vulnerable people [39, 40]. Facilitating a diagnostic process [41]. For example, Talking Mats was used to assess anxiety in children before an operation [41]. Improving social processes [30, 32]. For example Talking Mats could help people get to know someone or develop and maintain relationsh-ips [30, 32].
The use of Talking Mats was described in a wide variety of settings, such as home environments, institu-

The country indications are based on the description of the university or institution that was mentioned in the literature sources, which may have led to incorrect labelling. The use of “–“ indicates that no information about this theme was found in the literature. Column objectives:
tional care, rehabilitation, schools, and prisons. Target groups for which Talking Mats was used were:
people with specific communication difficulties (17 publications); people with learning disabilities (19 publications); people with dementia (12 publications); Older people who are frail (2 publications); people with Huntington’s disease (3 publications); children with and without communication impairments (7 publications); “Various target groups”, i.e. describing research in different settings with target groups not specifically mentioned, or not part of the above target groups (13 publications).
Related to the target groups for which Talking Mats can be used are the skills required to use it. The following skills were reported:
Physical skills to indicate the placement of the symbols, such as hand pointing or eye movements [32, 42]. Cognitive skills to understand the symbols [42, 43] and to understand the verbal instructions containing two or three information-carrying words [14, 31, 32]. Expressive skills to indicate a reliable yes/no (verbal or non-verbal) [14, 42].
Talking Mats can be tailored to the specific needs of target groups. The types and number of symbols, and the size, colour, and texture of the symbols and mat can be adjusted depending on the person’s communication challenges. For example, one can use a range of two to five top scale symbols (e.g. like/ dislike), depending on the person’s cognitive ability. In most cases, Picture Communication Symbols (PCS™), Talking Mats Communication Symbols [25], Sclera’s pictograms [44], or photographs are used for the symbols. Some symbol sets have been developed to reflect the World Health Organization’s International Classification of Functioning, Disability and Health (ICF) model, describing 9 different neutral domains of activity and participation [33, 45, 46].
Talking Mats is a partner-assisted communication framework. Although the intention of Talking Mats is to put the person who is communication vulnerable in control as much as possible, the communication partner has considerable influence [19]. The communication partner preselects the conversation topics and therefore has control over which items/topics are visually presented, and thus which topics are communicated about [19]. Furthermore, the quality of the conversation when using Talking Mats, e.g. the effects on facilitating communication and facilitating involvement, depends greatly on the support of the communication partner [10]. Factors that could possibly impact the quality of using Talking Mats are: the conversation partners’ questioning style; their prompting or making assumptions [19]; their preparation of the topics and symbols [1]; and their awareness of the symbols’ abstract nature [16, 47]. Ferm and colleagues [10] described that Talking Mats presupposes a speaking partner who is open-minded and respectful and who knows how to use Talking Mats.
Twelve articles reported research evidence for Talking Mats. The details of these articles are presented in Table 2. We found no systematic reviews, randomized controlled trials or cohort studies. There were seven cross-over studies in which the patients had a conversation without Talking Mats and a conversation with Talking Mats (numbers of patients ranging from 4 to 48) and five descriptive case series (numbers of patients ranging from 9 to 12). One of the case series was a qualitative study, another used mixed methods. Six of the 12 studies were carried out by researchers involved in Talking Mats Limited organization.
The studies in Part two focused on the target groups: people with aphasia, learning disabilities, dementia or Huntington’s disease, and children. No studies in Part 2 examined the skills required to use Talking Mats which were discussed in Part 1.
Tables 3 and 4 present an overview of the quality elements identified in the included publications. The qualitative studies often did not report the qualitative methods and data analyses in detail (Table 3), nor how the relationship between researcher and participants may have influenced the qualitative data gathering and analysis. In the quantitative studies, the design was often not described (Table 4). Moreover, in several studies the sample size was not justified and a convenience sample was mostly used.
The results are presented for each objective of Talking Mats: facilitating communication, facilitating involvement, and functional use of Talking Mats. Some studies reported on multiple objectives and are therefore described under several headings.
Facilitating communication
Ten publications reported on facilitating communication. They all reported results in favour of using Talking Mats. Six of these studies used quantitative variables (based on observations) clustered in coding frameworks [1, 2, 5, 7, 10, 11]. These six studies used three slightly different coding frameworks (see Box 1). Some of the elements of the coding frameworks were: participants’ understanding of the topic of discussion, participants’ engagement with each other, participants’ confidence, and researcher’s understanding of persons’ views [7]. The results show that the scores on these coding frameworks were higher when using Talking Mats (compared to usual conversation, structured conversation, or unstructured conversation) for young people with a learning disability, [2, 5] people with aphasia, [1, 7] and people with Huntington’s disease [10, 11].
Within the objective of facilitating communication, the use of Talking Mats was also studied with regard to more technical aspects of communication, based on researcher observations [5, 7, 10, 36]. Three studies focussing on these technical aspects reported positive results when using Talking Mats on the duration of the conversation, the number of topics, task behaviour, and perseveration. These results were identified for people with learning disabilities, dementia, and Huntington’s disease. One study focussing on the use of language by people with dementia did not find a difference when using Talking Mats. The details of the results are as follows:
Duration of conversation: In studies of people with dementia, Huntington’s disease and learning disabilities, the conversation lasted longer when using Talking Mats compared to an unstructured or usual conversation [5, 7, 10]. For example, in the study of people with Huntington’s disease, the conversations with Talking Mats had a mean duration of 28.31 min, compared to 3.67 min for an unstructured conversation, and 15.19 min for a structured conversation [10].
