Running head: PEER-MEDIATED, SOCIAL STORY INTERVENTION The Effects of Peer Mediated Social Story Intervention on the Social Interactions of Preschoolers with Autism Sanna Harjusola-Webb and Sophia Parke Hubbell Kent State University Kathleen Harris Seton Hill University November, 2010 PEER-MEDIATED, SOCIAL STORY INTERVENTION 2 Abstract Deficits in social communication skills are hallmark symptoms of autism spectrum disorders. There is significant evidence to support the use of Social Stories in interventions to address social communication skills in children with autism. However, there is little research on the use of social stories with preschool children with autism spectrum disorders. This single subject AB study extends the research on Social Stories to include the preschool age group. Additionally, this study introduces a potentially effective social communication intervention to the field of early childhood intervention in the form of a peer-mediated, Social Story intervention delivered via interactive whiteboard, though the results of the study were inconclusive. PEER-MEDIATED, SOCIAL STORY INTERVENTION 3 Today, one-third to one-half of young children with disabilities are enrolled in child care or preschool programs that include typically developing peers (Booth & Kelly, 2002; Diamond & Huang, 2005). As a result, many young children with disabilities are educated in communitybased programs alongside children without disabilities (Causton-Theoharis & Malmgren, 2005; Cook, Cameron, & Tankersley, 2007; Forlin & Hopewell, 2006; Hastings & Oakford, 2003; Shonkoff & Phillips, 2000). Convincing evidence exists to support the notion that integrated settings are “good” for all children and that they promote more positive peer interactions than segregated settings (CITATION). Inclusion for children with disabilities, however, is not a coincidental social experience and does not automatically translate into positive social interactions. In fact, without specific teacher supports or targeted interventions, the typical peers in inclusive classrooms tend to choose other typical peers as playmates instead of playing with the children with disabilities (Beckman, 1983; Devoney, Guralnick, & Rubin, 1974; Peterson & Haralick, 1977). Children with autism spectrum disorders (ASD), in particular, are at greater risk for experiencing loneliness, difficulty establishing and maintaining social relationships, and mental health problems due to a pervasive social dysfunction (APA, 2000). Indeed the word autism means within oneself (Kanner 1943), and the social impairments of children with ASD are often present across environments, people, and behavioral manifestations. Young children with ASD exhibit deficits in initiation, turn taking, joint attention and imitation behaviors (CITATION). As a result, the quality and quantity of social interactions with peers and adults is very different for children with ASD as compared to their typical peers. Some of these differences and deficits present in children with ASD might occur because of a negative feedback loop; the children with ASD produce fewer and poorer quality conversations, causing the adults and peers to respond PEER-MEDIATED, SOCIAL STORY INTERVENTION 4 less. This negative feedback loop has the potential to change the whole language and communication-related skills learning context experienced by the child with ASD. Descriptive research supports this theory by showing that the audio environments of children with ASD are different and include significantly less communicative input by adults and other children than audio environments of typical children (Warren at al, 2010). One solution for teachers to promote peer interactions in the context of natural environments is Peer Mediated Intervention. Peer-Mediated Interventions have been successfully used in integrated settings to increase the quality and quantity of social interactions with the children who have disabilities or limited skills in the area of social communication. PeerMediated Intervention (PMI) is an evidence-based strategy in which peers take on an instructional role with classmates or other children (Chandler, Lubeck, & Fowler, 2002; Conroy & Brown, 2004; Harper, Symon, & Frea, 2008; Harris, Pretti-Frontczak, & Brown, 2009; Kohler & Strain, 1999). PMI includes training in various social communicative strategies to foster socially appropriate behaviors. Research shows that using peers as role models has the potential to be more advantageous for increasing the quality and quantity of social behaviors in natural environments than teacher modeling (Guralnick, 2001; Utley, Mortweet, & Greenwood, 1997). Various approaches have been used to change the social communicative behaviors of peers and target children with autism. The PMI framework typically includes: (a) arranging the social and physical classroom environment to foster the use of PMI, (b) teaching peers specific strategies and social skills for initiating and responding to the target children, and (c) teaching appropriate social skills to the children with ASD. Peer-mediated intervention is technique in which typically developing peers receive training to support the development of a specific skill in a peer with a disability. The efficacy of peer-mediated interventions for children with autism PEER-MEDIATED, SOCIAL STORY INTERVENTION 5 in early childhood settings has been well established (Betz, Higbee, & Reagon, 2008; Gena, 2006; Kalyva & Avramidis, 2005; Kohler, Greteman, Raschke, & Highnam, 2007; Nelson, McDonnell, Johnston, Crompton, & Nelson, 2007; Trembath, Balandin, Togher, & Stancliffe, 2009). Across the literature, the common types of PMI strategies include: a) peer proximity, b) peer prompting and reinforcement, and c) peer initiation (Odom and Strain, 1984). The present study relied primarily on the peer proximity strategy. Peer proximity, is based on the premise that placing peers with children with disabilities increases the opportunities for social interaction. Peer proximity allows a natural interaction between children (Odom & Strain, 1984). For example, Christopher, Hansen, and MacMillan (1991) examined the impact of having a peerhelper assigned to a child with a disability. The peer helper was instructed to play near a child with a disability, for example, bringing a ball outside during recess and bouncing it next to the child with a disability. Peers can also interact by remaining close and having the child with a disability watch how a peer performs classroom activities and routines (Whitaker, 2004). Children with autism and peers met in weekly interaction sessions to promote shared play together and positive social behaviors. Peers were instructed to remain close and model appropriate play behaviors (e.g., following his/her lead, waiting for a turn, and turn taking) to children with autism during shared play. Peers encouraged play behaviors for children with autism using games and popular children activities. Carter, Cushing, Clark, and Kennedy (2005) found peer proximity successful with social activities during school hours. Peers assisted children with disabilities to learn a school locker coding system by remaining close and observing peers open and shut the lockers and encouraged children with disabilities to attend extracurricular activities together. In a similar study, peers were paired up with children with PEER-MEDIATED, SOCIAL STORY INTERVENTION 6 disabilities to be peer buddies during lunch and recess (Kamps et al., 2002). Overall, peer proximity has been investigated and has demonstrated results in increasing positive social behaviors with children with autism (McHale, 1983), withdrawn preschool children (Furman, Rahe, & Hartup, 1979), and mainstreamed academically handicapped children (Madden & Slavin, 1983). In addition, peer proximity has been shown to be successful with increasing positive social behaviors of children and youth with behavioral disorders (Bierman, 1986; Lord & Hopkins, 1986; Mathur & Rutherford, 1991). A Social Story is a story comprised of specific elements (i.e. types of sentences arranged according to a formula) that is used as a social skills intervention (The Gray Center, 2009). Social story interventions are simple to design and easy to implement in a classroom setting. Moreover, the use of peers as intervention agents is both practical in inclusive settings, and adds justification to the inclusive model of service delivery. In just the past five years, several studies have examined the use of social story interventions for improving social communication skills in children with autism (e.g. Delano & Snell, 2006; Ozdemir, 2008; Sansosti & Powell-Smith, 2008; Scattone, 2008; Scattone, Tingstrom, & Wilczynski, 2006). However, there is only one published study that examines the efficacy of such interventions on preschool children with autism (Crozier & Tincani, 2007). The primary purpose of this study is to examine the effects of a peer-mediated, Social Story intervention, delivered via an interactive whiteboard, on the social engagement of three preschool children with ASD during play with typically developing peers. The research questions therefore are (1) Does the peer training session increase the peer’s social communication attempts towards the children with ASD (target children)? (2) Does the peermediated, Social Story intervention increase the frequency of the target children’s social PEER-MEDIATED, SOCIAL STORY INTERVENTION 7 communication attempts toward their peers? (3) Does the peer-mediated, Social Story intervention increase the frequency and duration of mutual activity between the target children and their peers? Methods Participants The target participants in this study are three children who have been diagnosed with an autism spectrum disorder and who currently receive preschool special education services. The target children are all boys and all live in monolingual, English-speaking homes. Their ages ranged from 5-0 to 5-4 when the study began. They attend the same half-day, four-day per week, afternoon preschool special education class. Ethan uses short phrases and sentences to communicate. He is able to interact with peers appropriately at times, but more often requires adult support to engage meaningfully with peers. Ethan often sings to himself while working or playing. He perseverates on routines, going through specific motions repetitively (such as swiping an imaginary key card at each card reader he passes in the hallway without fail). Zachary relies on gestures paired with one- and two-word utterances to communicate. He will also imitate longer phrases and complete sentences, but rarely uses more than two-word utterances spontaneously. He frequently wanders the classroom, observing other children, but rarely joining them. Zachary depends on his routine to function and often has tantrums of screaming and throwing items when his routine is disrupted. Michael communicates using phrases and short sentences. His language is clear and easily intelligible. He prefers quiet solitary play, and rarely communicates with others unless he has a physical need (i.e. hunger, thirst, needs to use the toilet). Michael enjoys sorting and PEER-MEDIATED, SOCIAL STORY INTERVENTION 8 sequencing activities, particularly those dealing with letters or numbers. He is able to attend to an individual activity for more than 10 minutes at a time. He is able to read familiar and unfamiliar words by sight. He does not audibly sound-out new words. Although his word recognition skills are above age-level, his functional behavior skills are far below ageappropriate. Michael is able to follow one-step directions consistently, but inconsistently follows two-step directions. Seven peer models ages 4-9 to 5-1 participated in this study. Two peer models were identified and matched to each target child based on recommendations from the children’s teachers. One peer model acted as a substitute when any matched peer was absent. All of the target children demonstrated typical social and language skills for their ages. Additionally, their teachers reported that they were cooperative and likely to follow the directions of the research. Setting The study took place in a self-contained, preschool special education class for children with autism spectrum disorders or related needs in a public elementary school in Northeast Ohio. A media room in the school library was used during the intervention phase. Seven children were enrolled in the class. The adults in the class included one intervention specialist and two assistant teachers daily. Related service providers including a speech therapist, occupational therapist, vision therapist, and physical therapist were also in each of the classrooms occasionally during observations and data collection. The peer models were classmates in a half-day, afternoon, blended preschool program led by a general education teacher, an intervention specialist and two assistant teachers. The blended preschool classroom was two doors down the hall from the special education classroom. The students in the blended classroom included 7 children on IEPs and 14 children not on IEPs. PEER-MEDIATED, SOCIAL STORY INTERVENTION 9 Children from the blended class and the special education class interacted regularly during arrival and dismissal, and shared playground time together. Intervention Procedures This study used a single subject, AB, multiple-baseline across individuals design (Kazdin, 1982, p.132). The intervention (phase B) is a peer-mediated, Social Story intervention delivered using interactive whiteboard technology. The researchers created an interactive Social Story that addressed the target social engagement behaviors being measured. The interactive storybook format was created in PowerPoint and projected onto an interactive whiteboard. Interactive whiteboards (e.g. SMART™ Board, Promethean ActivBoard) are rigid presentation screens that are digitally connected to a computer and function similar to a touch screen computer monitor. When a user touches the interactive whiteboard with a special pen or wand, the whiteboard transmits information to the computer. Interactive whiteboard technology is well-suited for young children and individuals with special needs because it allows users to navigate digital content without the use of a mouse or keyboard. The interactive storybook allows the user to move through the story by touching the whiteboard with the special tool and clicking a button on the tool. When the child taps the board and presses the button, the story advances to the next page. A sound file automatically begins to play when the page advances. The sound file is the voice of a researcher reading the words on the page. Figure X Reasons for selecting in interactive Social Story: 1.

Optimizes social interactions between peers and children with disabilities Fully inclusive and integrated setting Requires active participation The first component of the intervention phase was a training session with the two peer models who were matched the first target child receiving the intervention. During the training session, the researcher navigated through the Social Story, modeling and describing the expected peer behavior during intervention. After listening to and watching the Social Story, the peers were instructed to retell the story as a method of checking their comprehension. Peers were instructed to talk to and play with the target child during the subsequent free-play time after each Social Story session. Peers were informed that they would receive a sticker for their participation each day. This process was repeated until, as a pair, the peers were able to navigate the story without adult assistance, retell the Social Story, and restate the directions. The training session was replicated for each set of peers just prior to the intervention onset for each target child. Dependent variables. The primary dependant variable is the time spent in mutual activity between the target child and peer(s). For the purpose of this study, mutual activity includes both parallel play and shared play. For parallel play, the target child and at least one of his peers must be engaged in related activities in the same activity center. The classroom had clearly defined activity centers for housekeeping, blocks, reading, art, computer, and table top work. For shared play, the target child and at least one of his peers must be engaged in the same activity. Table X PEER-MEDIATED, SOCIAL STORY INTERVENTION 11 Social Engagement Measures Communication Category Initiation Response Turn-taking Definition A spontaneous word, phrase, sentence, vocalization, gesture, or eye contact directed towards a peer with communicative intent. A word, phrase, sentence, vocalization, gesture, or eye contact directed towards a peer in reply to the peer’s initiation. Two or more initiation/response combinations on the part of one child (i.e. initiation-target child, response-peer, response-target child would be one instance of turn taking for the target child). Data collection Before beginning the baseline phase, background data about target children and peers was collected through teacher interviews, observations, and a review of relevant school records for the target children and the designated typical peers. During baseline and intervention phases, data was collected on both the target children and their corresponding peers. Each of the target children wore a LENA device during baseline and intervention sessions. LENA is a sophisticated, voice-activated audio recorder that also gathers information about the speaker and the distance between the conversation participants. The LENA device secured in a vest was put on children just prior to playtime during baseline and just before reading the Social Story during the intervention phase. Additionally, all sessions were video-taped for reliability purposes. One of every five sessions (including baseline and intervention phases) was coded by second researcher for interrater reliability purposes. The Social Story component of each session lasted between 5 and 10 minutes. If the target child was still engaged in the Social Story at 10 minutes, the researcher announced that it was time for play and guided the target child and peers to the door to leave the media room for play in the special education classroom. Data was collected during playtime for 10-15 minutes per session for all phases of the study. PEER-MEDIATED, SOCIAL STORY INTERVENTION 12 Results Figures and 1 and 2 illustrate the time Ethan, Zachary, and Michael spend engaged in a mutual social activity and frequency of their expressive communication with their trained peers during baseline and intervention conditions. INSERT FIGURES 1 and 2 Mutual Social Activity During baseline, Ethan spent most of the observed time not interacting with the other children present in the classroom. During the baseline, Ethan averaged 20 seconds per 10 minute observation (approximately 97% of the total observed time) session in baseline socially engaged in a mutual activity with the other children in the classroom. In summary, he spent most of the time engaged in solitary activity, not communicating verbally in the classroom setting. After the PMI training and interactive Social Story intervention phase begun, Ethan immediately increased the time he spent in mutual, social activity with the trained peers. Ethan’s data trend is variable in both baseline and intervention. However, the level change is positive and during the intervention condition his time spent in mutual activity with a trained peer increased to 3 minutes and 12 seconds on average. Table X Expressive Communication Means and Ranges Ethan Zachary Michael Baseline 101 (54-152) 92 (65-117) 11.2 (2-44) Intervention 83.9 (61-134) 127.4 (98-186) 66.75 (57-77) During baseline, Zachary spent, on average, 2 minutes and 37 seconds per 10 minute observation session mutually engaged with his classroom peers. His data trend during baseline is PEER-MEDIATED, SOCIAL STORY INTERVENTION 13 stable overall. However, during session 3, Zachary had a dramatic increase in the time spent engaged with a peer due to a joint book reading activity he initiated. This was considered an unusual behavior from Zachary. After the PMI training and interactive Social Story intervention, Zachary’s data show a slight increase in time spent in a mutual activity with trained peers—an average of 2 minutes and 48 seconds per 10 minute observation session. However, the data trend remains variable. During the baseline, Michael’s time spent in mutual activity with his peers was on average 28 seconds per 10 minute observation sessions. During the intervention, Michael increased the time he spent with his peers in a socially engaged and mutual activity to an average of 5 minutes of 43 seconds per an observation. Michael’s data show increases during the intervention condition, yet the data trend is variable. Expressive Communication The results from the automatic voice recognition tool, LENA, are presented in Figure 2. LENA was used to analyze the child audio output for both the target children with autism as well as their trained peers for conversational turn taking and word count. The results are somewhat variable for Ethan, however, the Zachary and Michael increased the rate of expressive communication after the onset of the intervention. Zachary and Michael’s data are stable with an increasing trend in the occurrence of the expressive communication and a positive change in the level. For Michael, no data overlap exists between the baseline and intervention phases. Ethan engaged in echolalia and frequent signing behavior (session 6) and LENA automatically coded this as expressive communication. In summary, the audio environment measured by expressive communication for the children with autism changed for 2 out of 3 children after the onset of the intervention condition. PEER-MEDIATED, SOCIAL STORY INTERVENTION 14 Discussion We were interested in finding a practical intervention that might increase the likelihood that children with significant social communication deficits participate more fully in inclusive preschool social contexts. The specific purpose of this study was to determine if a peer mediated interactive Social Story intervention could increase the duration and frequency of appropriate social engagement of preschoolers with autism and their peers in integrated classroom settings. This study extends the previous research on PMI and Social Story interventions by using an interactive whiteboard as the medium for the Social Story, by increasing the duration of the special engagement of children with autism and their peers, and without the addition of planned behavior management system or deliberate teacher monitoring system. This is the first published study to investigate the use of PMI with Social Stories. Further, it is the first study to examine the use of Social Stories presented with interactive whiteboard technology. Limitations The teacher was not able to manage the intervention because all of target children were in the same class. To maintain experimental control, it was necessary to remove each target child from his regular classroom to watch the Social Story with his peers during the intervention phase. The researcher implemented the Social Story component of the intervention and escorted the children to and from their classrooms to the multimedia classroom in the school library where the children watched and manipulated the Social Story on the interactive white board. Also, it is impossible to tease out the effectiveness of the PMI, Social Story, and interactive whiteboard components of this study. A larger study with control groups would be necessary to determine the effectiveness of each component of the intervention used in this study. PEER-MEDIATED, SOCIAL STORY INTERVENTION 15 Implications for practice Previous research has shown that simply placing children with disabilities in classrooms with their typical peers does not lead to meaningful interactions between children with disabilities and their typically developing peers. Rather, typically developing children tend to engage with each other. This study presents a potential model for meaningful inclusion of young children with autism. However, more research is needed on combining technology with other known effective intervention strategies for children with ASD, the efficacy of Social Story interventions with preschool-age children who have ASD, and how to create effective peer matches for PMI.
