Introduction: Learners with multiple disabilities and visual impairments (i.e., blindness or low vision) stand to benefit from accessible augmentative and alternative communication such as tangible symbols, but currently no evidence-based practices exist to guide intervention decisions. This study is a replication of previous research on Phase 1 of the Picture Exchange Communication System (PECS) adapted to teach students with multiple disabilities to exchange a tangible symbol for a preferred item. Methods: A multiple-probe single-case research design was used with three participants. Data were also collected to assess generalization, maintenance, and social validity. Results: A functional relation was observed, and all three participants achieved mastery criteria within 7–15 sessions. Although limited, generalization and maintenance data were promising. Social validity data showed families and professionals alike generally perceived the procedures and outcomes positively. Discussion: Results contribute to the growing body of evidence that adapted PECS Phase 1 is effective to teach students with multiple disabilities to use tangible symbols for basic requesting. Length of time to attain mastery criterion was longer for participants who were nonambulatory. Implications for practitioners: Practitioners should use efficiency data to plan for adequate time to support skill development, which will require collaboration and embedding opportunities into natural routines

Clinical Archives of Communication Disorders, 5, 31-41.Abstract: Purpose: We investigated the effects of behavioral skills training package with parents to use picture exchange communication system (PECS) with their children with autism spectrum disorder (ASD) to develop communication skills. Methods: Two parents and their children with ASD (one child per family) participated in this study. A multiple baseline design was used during the parents' training, and a changing criterion design was used during parents' implementation of PECS with children. Results: Results indicated that both parents implemented PECS intervention with their children with high procedural integrity and required minimal feedback through Bug-in-Ear at the end of the intervention. Moreover, both children acquired independent picture exchanges with their parents who implemented PECS training and generalized and maintained the skills. Conclusions: The findings suggest that when parents receive appropriate training and feed-back, they can train their children to use PECS to independently request desired items or activities. The current study extends existing research on PECS by teaching parents as the primary PECS trainers to implement the strategy with their children. 

A considerable number of studies have demonstrated that augmentative and alternative communication (AAC) is effective in increasing speech production in some children with autism spectrum disorder (ASD). Thus, this study aimed to (a) investigate the effects of a Picture Exchange Communication System (PECS) Phase IV protocol on the acquisition of spontaneous augmented requests, (b) evaluate the impact of progressive time delay and synthetic speech output on the development of vocal requests, and (c) determine the participants' preferences for each modality after reaching mastery. A multiple-baseline design across four children with ASD was used to measure the acquisition of augmented and vocal requests during the transition from low-tech to high-tech AAC systems. During a natural condition (i.e., playtime), a modified PECS Phase IV protocol was applied to teach the participants to request by producing multisymbol messages (e.g., I WANT þ names of a preferred item) using an iPad as well as vocalizations. After mastery, the participants' preference for using the modified PECS Phase IV app or the communication book was assessed by comparing the response allocations. The preliminary results suggest that the modified PECS protocol can be used to transition from a low to high-tech communication modality.

The Picture Exchange Communication System [PECS®) was first described in autism research literature in the early 1990s. Since that time, there have been almost 200 publications about the PECS protocol from countries around the world. The manualized PECS protocol has six key phases beginning with simple requests involving single icons, and building toward commenting, responding to other people's communication, and increased message length through picture combinations.1 We developed the protocol with very young children with autism spectrum disorder [ASDJ, but there are now publications involving adolescents and adults, as well as individuals with a wide variety of learning needs.

Functional communication skills are essential for all learners and must be promoted within all environments, including the home. During this time of home confinement, many families will need to look at opportunities for their children to use existing functional communication skills or even to acquire new skills. This article describes a set of 9 critical communication skills and provides a variety of examples of how families can improve the use of these important skills. Some of these involve speaker (expressive) skills, whereas others involve listener (receptive) skills.

Abstract: The purpose of this research was to compare the effectiveness of teaching two methods of image exchange communication system and matrix teaching on language skills and social skills of children with autism spectrum disorder. The method of this research was a semi-experimental method with a pre-test-post-test design along with a control group. The statistical population includes all children referred to autism centers in Qom city in 2021 who had symptoms of the disorder according to DSM criteria and were diagnosed with autism disorder according to the centers and experts. 45 people (9 girls and 36 boys) were randomly selected from autism centers in Qom province and randomly divided into two experimental groups and one control group. The experimental groups were subjected the 6-step treatment of the picture exchange communication system and matrix training individually for 3 months and 4 sessions of 15 to 20 minutes each week, and the control group did not receive any intervention. In this research, expressive and receptive and speaking language tests of Nyusha Development and Autism Social Skills Profile were used to collect data. The final results showed that there was a significant difference between the two groups of matrix training and PEC treatment (p<0.05). Based on the results, both interventions were effective, but it can be said that the communication system of image exchange is more effective in the language skills and social skills of children with autism spectrum disorder.

Introduction: It is both essential and significant to undertake research focused on the implementation of innovative educational methods within autism centers. Objective: This study seeks to investigate the impact of an intervention utilizing the Picture Exchange Communication System (PECS) within physical education (PE) settings on the physical activity (PA) levels and social skills of children diagnosed with autism. Conclusion: The findings of the current study indicate that the implementation of the PECS method facilitates the enhancement of communication abilities and increases PA levels among children with autism. This advancement in skills enables these children to achieve better control and regulation of their emotions and feelings. Consequently, this method can be regarded as an effective strategy for fostering emotion regulation skills and enhancing both social skills and PA in children with autism.

The purpose of the current study was to explore strategies to help parents support their child's PECS use at home. One child with ASD and both his parents participated. Researchers used behavioral skills training to teach target PECS skills and applied general case training strategies to actively program for generalization. A multiple baseline design across skills was used to monitor the primary parent trainee's fidelity during training sessions and a multiple probe design was embedded to monitor both parents' treatment fidelity in the natural environment with their child. The parent trainee demonstrated target PECS skills within the training setting. However, parents did not reliably demonstrate all target PECS skills in the generalization setting during follow-up.

The Picture Exchange Communication System (PECS) is an Augmentative and Alternative Communication (AAC) system which is widely used to support children with developmental disabilities. In the present study, we surveyed individuals responsible for implementing PECS in special educational settings in the United Kingdom (N=283). We explored knowledge of and adherence to the intervention, with a view to identifying training and support needs. Specifically, we examined participants’ knowledge, implementation accuracy, training experiences, access to resources, and attitudes towards PECS. We developed hierarchical logistic regression models to explore the association between training experience and both knowledge and use of PECS. We pre-registered our methods, predictions and the analysis plan on the Open Science Framework (OSF). We found considerable variation in practitioner knowledge and implementation of PECS. Formal training predicted greater knowledge and more accurate implementation when practitioner role and the degree of setting support were accounted for. While PECS was rated by a large majority to be effective and practical, many participants identified that time and the availability of resources were barriers to implementation. We also found that the purpose of PECS was not always fully understood by practitioners, and we identified some consistent gaps in knowledge and implementation. This study contributes new information regarding the real-world use of PECS in educational settings and offers new insights for supporting practitioners.

PECS training for children with Autism Spectrum Disorder and Intellectual Disabilities has been extensively evaluated. In contrast, there is a dearth of literature on outcomes of PECS training for adults lacking functional communication skills. A literature search produced five empirical studies involving PECS training with 18 adults. The participants involved presented with a wider range of intellectual and physical challenges than those typically found in child-related research. Where noted, severity of diagnoses ranged from mild to profound and included participants with single, dual and triple diagnoses, the majority with dual diagnoses. Each of the studies shows results in line with child-related research. While the amount of research is limited, the outcomes of these few studies are profound in their implications for adults with a variety of intellectual disabilities and physical challenges. Implications for both children and adults are considered.

Communication deficits are one of the core symptoms of autism spectrum disorder (ASD). As such, individuals diagnosed with ASD are often taught to communicate using augmentative and alternative communication (AAC) systems. One of the most commonly used AAC systems is the Picture Exchange Communication System® (PECS®). Despite the prevalent use of PECS within clinical and educational settings, there exists little empirical information about the use of PECS in community settings, such as summer camps. The present preliminary investigation explored the nature of participants’ PECS use in a community setting using various sources of data from multiple respondents. Fidelity of PECS implementation was also examined. Twenty-two children and youth, the majority of whom scored substantially below average on standardized measures of cognitive and adaptive abilities and in the “severe” range of ASD symptomatology, were taught to use PECS within a therapeutic summer camp. Overall, results indicate that participants were reported to use PECS to request a diverse array of reinforcing items, across a variety of activities and environments. Increased PECS use and appropriate communicative behavior was observed, as well as reductions in contextually inappropriate behavior. Results were reported by parents to generalize to the home environment. Further, PECS was implemented with adequate fidelity by community implementors. Implications for communication training within community settings are discussed.

The aim of the study was to empirically assess the efficacy of Picture Exchange Communication System (PECS) in 5 children with autism spectrum disorder (ASD). This study was also intended to report parental feedback on using PECS with their children. Results: Current study shows that all the children were able to use PECS spontaneously and independently without any physical prompts. Children were able to generalize PECS at home with ease and were able to initiate communication on their own using the pictures. The mothers of the children reported that they observed a drastic subsidence in children's challenging behaviours and also improvement in their attention span. The findings from our study showed that PECS training is effective in improving the socio-communication skills in children with ASD who had restricted communication. On analysing the report, mothers stated that they were able to easily incorporate PECS at home with their child as it implements the use of actual pictures for communicative exchange. As PECS training paves the way for expression of the child's needs, there was also a significant reduction in the children's behavioural problems such as tantrums and other self-injurious behaviours. Conclusion: From this study, it can be concluded that PECS training is effective in improving various communicative temptations in socio-communication skills in children with ASD who have restricted communication. It was also noted that obtaining parental feedback periodically would help in generalization and it encourages the parents' involvement in the child's learning process.

Autism spectrum disorder (ASD) is an interplay between biological, social and environmental factors that impact the development of individuals. However, core characteristics are social, communication and behaviour challenges that restrict children’s participation in society. Consequently, there are discussions regarding the need for society to develop interventions that are geared towards promoting the participation of children with ASD in societies. While the Picture Exchange Communication System (PECS) helps lessen the biological characteristics of children with ASD, its impact has rarely been explored in non-western societies, such as the United Arab Emirates (UAE). Objectives: The instant study’s purpose was to explore parents’ perceptions of the effectiveness of the PECS on the communicative, social and academic developments of children with ASD in UAE. Results: The results revealed that the parents were generally positive about employing the PECS to support the development of their children with ASD. There was also a positive association between using the PECS and improving communication, learning and social skills in children with ASD. Conclusion: It is imperative that educators and policymakers envisage parents as equal partners in providing rehabilitation services to children with ASD. Various implications, such as the need for continual engagement and empowering parents of children with ASD, are discussed.

The aim of this study was to evaluate a program for implementing of the PECS in children with non-verbal ASD or with minimal verbalization in a school clinic belonging to the Unified Health System - SUS.

Purpose: The aim of this study was to evaluate a program for implementing of the PECS in children with non-verbal ASD or with minimal verbalization in a school clinic belonging to the Unified Health System - SUS. Methods: This is a longitudinal study. The sample consisted of 22 children with nonverbal ASD or with minimal verbalization; 17 boys and 5 girls, aged 6 to 12 years old. The program consisted of 24 sessions of individual speech language therapy with the presence of the family member and followed the six phases originally proposed by the PECS Training Manual. Results: All children reached the first three phases. About 82% reached phase IV; 64% phase V and 19% phase VI. Family adherence was 96%. Conclusion: It was possible to test a PECS implementation program in 24 sessions and verify that children were able to achieve phases of discrimination and sentence construction, besides demonstrating gain in their lexical repertoire and reduction of non-adaptative behaviors.

The implementation of Picture Exchange Communication System (PECS) strategy in this research aimed to improve children’s speaking ability. The indicators of speaking ability are child understands the meaning of the word used, able to connect the word to the denoted object, and to pronounce words understood by others. In other word, child is able to repeat sentences, ask questions with the correct sentence, and express opinions to others. This study uses qualitative method with the type of action research. The study was conducted in two cycles, with 3 meetings in each. The design of this study starts from the planning, implementation, observation, and reflection. The participants were 17 children aged 4-5 years old of group A1 TK ABA 4 Mangli Kaliwates Jember. The result showed that prior to PECS the children's speaking development rate was 17%, after the PECS action the speaking ability increased from 35% in the first cycle to 88% in second cycle. This shows that the speaking ability of early childhood can be improved with PECS approach.

Results: Participants who achieved high phases of PECS (≥PECS phase IIIb) differed significantly from those who mastered lower PECS phases (≤PECS phase IIIa) in terms of overall, verbal, and nonverbal mental age, matching abilities, and adaptive behavior level. Stimulus generalization was also associated with significant variation in PECS outcome. PECS outcomes could be predicted with good accuracy using a combination of these child characteristics and treatment variables. Conclusions: The findings from the current study suggest that children with relatively higher cognitive and adaptive skill levels are more likely to achieve higher phases of PECS; further, approaches to generalization training also play a role. Factors such as autism symptom severity and parental ratings of maladaptive behavior were not associated with significant differences in PECS outcomes. However, more research is needed. Implications: Gaining a better understanding of predictors of PECS outcomes is important to inform intervention, provide more accurate outcome expectations for families, and guide PECS teaching procedures. Although participants were more likely to achieve higher phases of PECS if they had a higher mental age, adaptive skill level, and matching skills, the average scores for these measures were well below those expected for same age peers. These results indicate that PECS is appropriate for use with children with clinically significant deficits in cognitive and/or adaptive abilities. Further, results suggest that even children who demonstrate more severe symptoms of autism and exhibit more challenging behavior can achieve higher phases of PECS.

Background: Children with communication impairments-such as autism spectrum disorder or global developmental delay-face significant challenges affecting their emotional and behavioural development. The Picture Exchange Communication System (PECS) is an augmentative communication tool designed to enhance their skills. However, its effectiveness can vary in resource-limited settings. This study aimed to identify predictors of successful PECS training among children with communication impairments in such environments. Conclusions: In resource-limited settings, factors such as severity of impairment, intensity of intervention, socioeconomic status and caregiver involvement significantly influence the success of PECS training. Tailored interventions and strategic resource allocation are crucial to optimise communication outcomes for these children.

O objetivo deste estudo foi avaliar um programa de implementação do PECS em crianças com TEA em clínica-escola pertencente ao Sistema Único de Saúde - SUS.

Caregivers are generally children’s primary communication partners; therefore, their ability to support their child’s use of augmentative and alternative communication systems, such as the Picture Exchange Communication System (PECS; Frost & Bondy, 2006), is critical. However, few studies explore systematic approaches to PECS caregiver training and little is known about how to efficiently and effectively support caregivers’ PECS implementation. The purpose of the present study was to evaluate the feasibility and preliminary effectiveness of a 2-week telehealth training package using behavior skills training and general case training to teach caregivers to implement PECS (i.e., the PECSperts Caregiver Training Package). Six caregivers of children on the autism spectrum participated in the study, four mothers and two fathers. Feasibility was evaluated across the areas of acceptability, service demand, community implementation, practicality, and limited effectiveness testing (Bowen et al., 2009). The training was evaluated using a modified concurrent multiple probe across behaviors research design. Caregivers reported a high degree of satisfaction with the training, and high rates of session attendance and study engagement were observed. Caregivers achieved high levels of PECS teaching accuracy for all the phases of PECS targeted in the training (i.e., phases 1 to 3b). Results persisted at 1- and 2-month follow up probes. The results indicate that a brief telehealth model may be an effective approach to PECS caregiver training and may be feasibly implemented in community settings. The results support the need for future research exploring the effectiveness of the training on children’s PECS use.

The objective of this research was to assess the efficacy of behavioral therapy interventions in the treatment of autism spectrum disorders (ASD). The study utilized the PubMed and Embase databases to locate randomized controlled trials, quasi-experimental treatment studies, and randomized clinical trial comparisons. The experimental group received treatment based on an applied behavioral approach, such as PECS, DTT, PRT, TEACCH, ESDM, and EIBI. After examining seventeen studies, the researchers found that each type of behavioral intervention had a positive impact. Naturalistic protocols that employed PRT and PECS improved ASD symptoms in general, despite their targeting of particular cognitive domains such as language. ESDM enhanced receptive language, particularly in preschool-aged children. Structured and integrated interventions, like EIBI and TEACCH, improved overall adaptive functioning. Combining DTT with a TEACCH program produced greater benefits in linguistic, affective-social, and personal autonomy domains. However, there is a scarcity of high-quality research available on behavioral interventions for ASD. Further comparative studies are necessary to identify cost-efficient interventions. For example, PRT and PECS significantly improved social communication skills in only 15–40 hours over six months. The authors emphasized the need for continued research and the application of evidence-based interventions in specialized settings.

Purpose: The aim of this study was to analyze the repercussion of the implementation of PECS on the burden index of mothers of children with Autism Spectrum Disorder (ASD). Methods: This was a longitudinal study (CEP 0403/2017). The sample consisted of 20 mother and child with ASD. The mothers were on average 41 years and 5 months and the children were 7 years and 2 months old. Fifteen children were male and five were female. The Brazilian version of the Burden Interview scale was applied to verify the level of caregiver burden. The Autism Behavior Checklist (ABC) was applied to the analysis of non-adaptive behaviors and to analyze the lexical repertoire: Auditory and Expressive Vocabulary Tests. The PECS Implementation Program was composed of 24 sessions of individual speech therapy with the active presence of mothers. At the end all children and mothers were reevaluated with part of the instruments. Results: There was a tendency to reduce maternal overload indexes after the implementation of the PECS. There was a significant decrease in non-adaptive behaviors and an increase in the expressive and auditory vocabulary indexes of the children at the final moment of the study. We did not observe a significant correlation between the degrees of overload with age, schooling and intellectual quotient of children, nor schooling and maternal socioeconomic status. Conclusion: It was possible to analyze the repercussion of the implementation of the PECS on the burden of mothers of children with ASD assisted by the Program.

Results: The findings revealed that picture exchange communication systems is the most common communication system used to support the development of functional communication. The most common functions enabled by the communication systems were choice-making and making requests. Several barriers (e.g., individual factors related to adults with severe/profound intellectual disability, others' attitudes, behaviour and knowledge) to and enablers (e.g., accessibility and availability of the communication system, training for those supporting adults with severe/profound intellectual disability) of functional communication were identified. Conclusions: Removing the barriers and enabling functional communication is essential to developing the functional communication of adults with severe/profound intellectual disability.

It is known that some autistic individuals are considered non-verbal, since they are unable to use verbal language and barely use gestures to compensate for the absence of speech. Therefore, these individuals’ ability to communicate may benefit from the use of the Picture Exchange Communication System – PECS. The objective of this study was to verify the most frequently used words in the implementation of PECS in autistic children, and on a complementary basis, to analyze the correlation between the frequency of these words and the rate of maladaptive behaviors. Methods: This is a cross-sectional study. The sample was composed of 31 autistic children, twenty-five boys and six girls, aged between 5 and 10 years old. To identify the most frequently used words in the initial perio of implementation of PECS, the Vocabulary Selection Worksheet was used. And to measure the rate of maladaptive behaviors, we applied the Autism Behavior Checklist (ABC). Results: There was a significant prevalence of items in the category “food”, followed by “activities” and “beverages”. There was no correlation between the total amount of items identified by the families and the rate of maladaptive behaviors. Conclusion: The categories of words most mentioned by the families could be identified, and it was confirmed that the level of maladaptive behaviors did not interfere directly in the preparation of the vocabulary selection worksheet for the children studied.

Sabe-se que alguns autistas são considerados não verbais, uma vez que não são hábeis para utilizar o código linguístico. E tampouco usam gestos para compensar a ausência de fala. Sendo assim, a habilidade comunicativa desses indivíduos pode ser beneficiada pelo uso do sistema de comunicação alternativa Picture Exchange Communication System – PECS. O objetivo deste estudo foi verificar os vocábulos mais frequentemente utilizados na implementação do PECS em crianças autistas. E, de forma complementar, analisar a correlação entre a frequência destes vocábulos e o índice de comportamentos não adaptativos.

Research indicates that the Picture Exchange Communication System® (PECS®) is an evidence‐based communication approach for children diagnosed with autism spectrum disorder (ASD). However, little is known about PECS‐related parent training, treatment fidelity, or generalization and maintenance of skills. The purpose of the current study was to explore strategies to help parents support their child's PECS use at home. One child with ASD and both his parents participated. Researchers used behavioral skills training to teach target PECS skills and applied general case training strategies to actively program for generalization. A multiple baseline design across skills was used to monitor the primary parent trainee's fidelity during training sessions and a multiple probe design was embedded to monitor both parents' treatment fidelity in the natural environment with their child. The parent trainee demonstrated target PECS skills within the training setting. However, parents did not reliably demonstrate all target PECS skills in the generalization setting during follow‐up.

Educational professionals (EPs) are expected to be knowledgeable about the use of the Picture Exchange Communication System (PECS). This study aims to explain the perspectives and experiences of EPs regarding their familiarity with and understanding of PECS, as well as the barriers to successful PECS usage. This study uses a qualitative descriptive approach to investigate PECS usage in Saudi governmental educational institutions serving children with autism spectrum disorders (ASD). In-person semi-structured interviews were conducted with 11 EPs. The inductive thematic analysis of the interview extracts reveals that EPs have limited knowledge of PECS, a lack of understanding of its implementation procedures, and insufficient training. Barriers to the successful implementation of PECS were also revealed, including a shortage of assistant teachers, low parental awareness, and limited parental collaboration. EPs expressed negativity regarding the availability of PECS tools and highlighted a need for resources. The findings suggest that there are areas for improvement in terms of PECS practices in schools and identify several barriers—organization-related, school-related, family-related, and child-related—that should be taken into consideration when implementing PECS with children with ASD. Based on the qualitative results, this study provides suggestions for further research as well as implications for practice. Barriers to the use and implementation of PECS are identified. The results will be helpful for schools regarding the provision of the necessary tools and training for PECS application as well as for policy makers who need to consider employing assistant teachers to assist EPs with the development and implementation of PECS

The picture exchange communication system (PECS) is an evidence-based communication intervention designed to improve communication skills in people with limited to no functional speech. Because of this, professionals frequently look for opportunities to receive training in how to implement PECS. Though most training methodologies have included robust, and time intensive, training methodologies, one recent study used video modeling (VM) with voice-over instructions and text descriptions to train three future professionals in the implementation of PECS. Thus, to find even more efficient and effective training methodologies, this study aimed to train future professionals in the first three phases of PECS using VM alone and, if necessary, verbal feedback. A nonconcurrent multiple baseline design across three participants was used in the study. The results indicated all three participants demonstrated an immediate change in skills following VM alone, with only one participant requiring brief feedback in Phase 1. This was further evidenced by large effect sizes. Thus, results indicate that training future professionals using VM was both more efficient and equally effective when compared to previous training methodologies.
