Differences in social communication are common in highly verbal autistic adolescents and can interfere with development of friendships as well as lead to other co-occurring challenges. The purpose of this initial study was to assess whether targeted areas of social communication would improve following the implementation of a manualized social communication package with parent participation and school coordination. Autistic adolescents who demonstrated challenges with social communication participated in this study in the context of a rigorous concurrent multiple baseline experimental design.

There has been a steady increase in the number of children diagnosed with autism spectrum disorder (ASD) worldwide. However, screening tools that focus primarily on communicative development that are culturally sensitive and linguistically appropriate are needed, particularly in languages, such as Farsi, which is spoken in countries that may benefit from additional resources. Therefore, the purpose of this study was to develop and validate a screening tool, written in Farsi by Iranians, that focuses on communication and factors affecting the development of communication for children with autism.

Children diagnosed with autism spectrum disorder (ASD) demonstrate challenges in various areas of social communication. The aim of this study was to examine the effect of Pivotal Response Treatment (PRT) targeting question-asking on brain activity in twenty 6-12-year-old autistic boys, using a Randomized Clinical Trial (RCT) design. Verbal children, diagnosed with autism, who lacked question asking in their communication were matched based on age and mean length utterance (MLU) and were randomly placed in either PRT intervention or treatment as usual (TAU) groups.

Many individuals with Autism Spectrum Disorder (ASD) experience challenges with social communication, including recognizing and responding to non-verbal cues. The purpose of this study was to assess the efficacy of self-management combined with textual cues to teach adults with ASD to recognize and respond to nonverbal expressions of boredom and confusion during social conversation. A multiple baseline across participants design was used to assess the efficacy of this intervention for three participants.

Purpose Individuals with autism spectrum disorder (ASD) often have difficulty asking questions during social conversation, which can negatively impact their interactions with peers. The purpose of this study was to assess whether a question bank intervention would be effective in improving question asking during social conversation. Method In the context of a multiple-baseline experimental design, we implemented an intervention using prepractice with question banks designed to increase the number and diversity of questions asked by adolescents and adults with ASD during social conversations with their peers.

Purpose The purpose of this systematic review was to identify parent education procedures implemented in intervention studies focused on expressive verbal communication for nonverbal (NV) or minimally verbal (MV) children with autism spectrum disorder (ASD). Parent education has been shown to be an essential component in the habilitation of individuals with ASD. Parents of individuals with ASD who are NV or MV may particularly benefit from parent education in order to provide opportunities for communication and to support their children across the life span.

This systematic review examined definitions of "nonverbal" or "minimally verbal" and assessment measures used to evaluate communication in intervention studies focusing on improving expressive verbal communication in children with autism spectrum disorder (ASD). We reviewed sample size, number of participants, participant age, and male/female representation. Our analysis yielded relatively few studies with non/minimally verbal children with ASD focusing on verbal expressive communication.

Children with autism spectrum disorder demonstrate challenges in socialization that can interfere with their participation in common childhood activities and can persist or worsen if not addressed. The purpose of this study was to assess whether individualized education program (IEP) social goals could be targeted by a supervised paraprofessional during a short-term inclusive summer camp program. Data were collected using a concurrent multiple baseline design across four children.

Research has demonstrated that incorporating restricted interests of an individual with autism into recess activities is effective at increasing socialization with typically developing peers. However, certain activity contexts may alter the reinforcing influence of the restricted repetitive behaviors (RRBs) depending on an individual's history in that activity. Using an alternating treatment design, this study examined whether an individual's history with an activity affected socialization.

Recent research suggests that children with autism spectrum disorder (ASD) may now be reliably identified in later infancy, highlighting the need for empirically-validated interventions for infants and toddlers with early symptoms of ASD. Using a multiple baseline design across 15- to 21-month-old toddlers, this study implemented a brief, parent-mediated, Pivotal Response Treatment program, focusing on improving expressive communication. The results indicated that verbal communication improved as a consequence of the intervention, with concomitant improvements in untreated areas for all participants.

Children with autism often demonstrate disruptive behaviors during demanding teaching tasks. Language intervention can be particularly difficult as it involves social and communicative areas, which are challenging for this population. The purpose of this study was to compare two intervention conditions, a naturalistic approach, Pivotal Response Treatment (PRT) with an adult-directed ABA approach on disruptive behavior during language intervention in the public schools.

Early detection methods for autism spectrum disorder (ASD) in infancy are rapidly advancing, yet the development of interventions for infants under two years with or at-risk for ASD remains limited. In order to guide research and practice, this paper systematically reviewed studies investigating interventions for infants under 24 months with or at-risk for ASD. Nine studies were identified and evaluated for: (a) participants, (b) intervention approach (c) experimental design, and (d) outcomes.

Accumulating studies are documenting specific motivational variables that, when combined into a naturalistic teaching paradigm, can positively influence the effectiveness of interventions for children with autism spectrum disorder (ASD). The purpose of this study was to compare two applied behavior analysis (ABA) intervention procedures, a naturalistic approach, pivotal response treatment (PRT) with a structured ABA approach in a school setting. A randomized clinical trial design using two groups of children, matched according to age, sex and mean length of utterance was used to compare the interventions.

An important line of research relates to whether school personnel, such as paraprofessionals, who are present during unstructured social periods, such as lunch-recess, could successfully implement interventions to improve socialization between students with ASD and their typical peers in a group setting. Therefore, within the context of a multiple baseline across participants design, we assessed whether training paraprofessionals to provide social interventions would enhance social development in students with ASD in a group setting. Results showed that paraprofessionals who were not providing any social opportunities during baseline were able to meet fidelity of implementation following a brief training.

There has been a dramatic rise in the number of children being diagnosed with autism spectrum disorders (ASD), which has led to increased attention paid to assessment and intervention issues. This manuscript agrees with Camarata (2014) that the evidence base for early assessment and intervention should be expanded. However, it disagrees with Warren et al.

Individuals with autism spectrum disorders often exhibit difficulties with reciprocal social conversation, engaging in limited verbal exchanges, even when language structures are intact. This study employed a multiple baseline design to examine the effectiveness of a self-management intervention targeting (1) on-topic responsiveness to a conversational partner; (2) expansion of the conversational topic; and (3) on-topic question asking. Results demonstrated improved reciprocal social conversation through elaborated responses and on-topic question asking, which generalized and maintained.

Social initiations make up a core deficit for children with autism spectrum disorder (ASD). In particular, initiated questions during social interactions are often minimal or absent in this population. In the context of a multiple baseline design, the efficacy of using the motivational procedures of Pivotal Response Treatment to increase social question-asking for three young children with autism was assessed.

Prescription medications are commonly used for children with autism spectrum disorder (ASD), however, there is little research regarding how the effect of medication is monitored across settings once prescribed. The present study addressed this issue for children with ASD in school by administering a questionnaire to teachers of students with ASD who were and were not being given medication. Specifically, the questionnaire assessed the teachers' knowledge about whether the child was being given medication, and whether behavior changes or side effects were being communicated in any way to the child's family and prescribing physician.

Verbal initiations, such as questions, are essential components of social conversation often lacking in children with autism. Building on research showing that single questions can be taught in isolation, this study used a multiple baseline design to investigate whether a self-management intervention was effective for teaching concurrent acquisition and discrimination of three social questions in the context of conversation. Following intervention, participants rapidly increased their appropriate use of all three questions in a conversational context and maintained these gains over time.

Children with Asperger's Disorder often have difficulty with peer relationships and socialization. The current study assessed whether peer social interactions would improve in school settings if an intervention was designed that incorporated the children with Asperger's interests. Three children who were fully-included in regular education classes but did not interact with peers prior to intervention participated in this research.

Social engagement by children with autism spectrum disorder (ASD) in unstructured school settings generally occurs at very low levels, if at all. Although many interventions improve peer socialization, generalization and maintenance of such gains when interventions are faded are typically low. The present study employed a multiple baseline design across participants to target generalization in the absence of interventionists in elementary school children with ASD at recess.
