Abstract
As more students with an intellectual disability are attending postsecondary programs at colleges and universities, these students are presented with new opportunities for socialization (e.g., conversing with peers and faculty across campus environments, joining organizations of interest, and participating in campus events). The generalization of social skills to new settings and classrooms with unfamiliar people may be challenging for some individuals with an intellectual disability. We conducted a single-case study using a multiple baseline design across student and peer pairs to evaluate the effects of peer training on the social communication of students in rural college classrooms. Specifically, we collected data on students taking three or more turns during conversations, initiating or responding to their peer partners, and discussing academic or social topics (communication function) using partial interval recordings. After a brief training session with peers, all students increased the percentage of intervals taking three or more turns, with the majority of student responses focusing on academic content. We conclude the article by discussing key findings, limitations, future research directions, and implications for practice.
Life after high school is a topic of high priority for students and their family systems. Graduates may seek opportunities to attend college, technical training programs, or join the workforce. Students with intellectual disability (ID) and their families, including those from rural communities, often have similar dreams and aspirations for life after high school (Collet-Klingenberg & Kolb, 2011). Increasingly, students with ID are seeking opportunities to access and benefit from a postsecondary education (PSE) on college campuses (Griffin, Mello et al., 2016; Think College, 2020). The campus environment can be daunting for some students with ID as it requires higher levels of autonomy than in most traditional K–12 settings, especially those more restrictive educational placements (e.g., self-contained special education classrooms). Furthermore, participation by students with ID in PSE is relatively new; thus, questions still remain as to how to provide adequate supports in these complex less structured environments (Alpern & Zager, 2007; Love & Mock, 2019).
Over the last few decades, more than 300 specialized PSE programs have been established to provide academic, social, and job-related college experiences for students with ID (Think College, 2020). These experiences yielded a 65% employment rate for individuals with ID who participated in PSE programs in comparison to 19% for people who did not attend a PSE program (Grigal et al., 2018). Compared with those who only had a high school education, graduates from PSE programs worked nearly 50% more hours and in turn earned US$80 to US$95 more per week (Cimera et al., 2018; O’Neill et al., 2015). While the outcomes of these programs present numbers that justify such efforts, the components of those experiences are the pieces that facilitate individual success, especially in rural communities (Love & Mock, 2019). The focus of these PSE programs is on academic enrichment, socialization, independent living skills (including self-advocacy), and integrated work experiences to develop skills for future employment (Hart et al., 2010).
Social communication plays a crucial role in the routines of daily life, especially at college. Gilson and Carter (2016) found that increased social interactions in college students with ID or autism spectrum disorder were related to higher levels of task engagement, further highlighting the importance of providing and engaging individuals in more social opportunities. Individuals with ID also have been found to have smaller, less diverse social networks than their peers without disabilities (Eisenman et al., 2013), especially for those individuals living in rural communities with limited transportation and online access (Ryan, 2014). Despite data indicating students in inclusive PSE programs spend approximately 75% of their time with peers without disabilities (Moore & Schelling, 2015), it is still unclear as to how to capitalize on these opportunities to support students’ social engagement and facilitate the acquisition of new social skills in the college setting.
Gena and colleagues (1996) demonstrated that social skills instruction in the natural environment can facilitate generalization to different situations and settings and maintenance over time. Instruction in naturalistic environments may provide learners the opportunity to perform skills and connect with reinforcers naturally occurring in typical settings (e.g., peer attention). Researchers have demonstrated the effectiveness of instruction in natural settings on college campuses (e.g., Alpern & Zager, 2007; Gilson & Carter, 2016). Furthermore, several research teams have incorporated the use of peer mentors to support intervention in inclusive college environments (e.g., Chung et al., 2012b; Hafner et al., 2011; Jones & Goble, 2012; Workman & Green, 2019).
For students with ID on college campuses, peer mentors have been found to serve as effective models of contextually appropriate social behaviors and to assist in facilitating students’ engagement in new social activities. For example, Hafner and colleagues (2011) paired undergraduate students with students with ID who were participating in an inclusive PSE program at a college. The undergraduate students served as peer mentors, taught their partner with ID social norms, and provided opportunities for their partners to engage in social activities on campus. In this inclusive model, peer mentors acted as the primary facilitators, assisting students with ID beyond academic and social integration by helping students manage time, participate in classes, and understand the social aspects of the college classroom. The peer mentors also reported favorable perceptions related to their training on supporting their partners with ID. Similarly, Jones and Goble (2012) demonstrated the effectiveness of training peer mentors. Following peer training, the mentors successfully supported college students with ID in navigating the college experience and demonstrating to others their strengths. Although the findings of both qualitative studies are encouraging, there is a need for more research to establish the effectiveness of peer-mediated supports for improving social skills in college settings.
Beyond presenting social opportunities and models, peer mentors can provide additional benefits, including expanded communication functions, increased competency of communication partners, and nurtured potential for developing friendships (Chung et al., 2012b). In a systematic review, Chung et al. (2012b) examined 31 single-case intervention studies aimed to increase peer interactions for students with complex communication needs (CCN) in Grades 1 to 12. More than half of the reviewed studies involved peers as the intervention agents. Following training, peers without disabilities serving as instructors, peer network members, or conversational partners delivered supports that produced improvements in social communication outcomes for students with CCN across grade levels.
As previously noted, there is evidence highlighting the importance of social communication in academic, social, and job settings within PSE programs (e.g., Cimera et al., 2018; Grigal et al., 2018; O’Neill et al., 2015) and the meaningful impact of peer mentors in grade-level settings (Chung et al., 2012b). Considering the potential effectiveness of using peers to facilitate social interactions and a dearth of available research in promoting students’ acquisition of social skills in PSE settings (Blumberg & Daley, 2009; Pennington et al., 2021), additional investigations in this area are warranted. Furthermore, there is a need to investigate the use of peer supports on college campuses in rural settings. Rural communities and colleges may present unique opportunities and challenges for establishing peer supports for students with ID (Collet-Klingenberg & Kolb, 2011). In an effort to expand the research in this area, we explored the following research questions:
Method
Participants
Two postsecondary students with ID (Zion and Tori) and three peer partners without a disability (Adrian, Tenley, and Piper) participated in this study. Zion and Tori met the inclusion criteria of (a) having a primary diagnosis of ID, (b) enrolling in a postsecondary program in a rural community, (c) attending at least one college course throughout the semester, and (d) having the need to improve social communication as reported by teachers and/or parents. After Zion and Tori and their guardians signed the consent forms, their corresponding peer partners who attended the same college courses and sat in close proximity were invited to participate in the study. At the start of the semester, the PSE program director selected and assigned peer partners based on areas of shared interest and schedules. Each peer partner also provided consent on a voluntary basis.
Zion, a 21-year-old White male in his third year of the postsecondary college program, attended a 2D Art course and worked at a dining hall on-campus and at a community aquatics center off-campus. In previous semesters, he took physical education courses (Team Sports and Cooperative Games) and worked at Chick-Fil-A as a dining room assistant and at a local sheriff’s office completing various jobs. His interests included drawing, cleaning, swimming, caring for his dogs, and playing video games. Some of his areas of improvement were learning to respond appropriately when given feedback from teachers, managers, and job coaches and increasing the number of tasks completed at work.
Tori, a 21-year-old White female in her third year of the postsecondary college program, attended an Introduction to Special Education course and worked at a dining hall on-campus and at a veterinarian clinic off-campus. She hoped to become a special education paraprofessional or veterinarian assistant one day. She took University 100 and an art course during previous semesters. She enjoyed bowling, playing games, and crafting during her free time when she was not studying and practicing for her driver’s license. Her goals included increasing (a) comfort in hearing her own voice and (b) the number of tasks she completed at work.
Both Adrian and Tenley were 21 years old and graduating in the spring as a fourth-year senior. Adrian, a White male, declared recreational therapy as his major and had no prior experience working with people with a disability. Tenley, a multiple race female majoring in English, had 1 year of experience supporting individuals with a disability at college. Piper was a 20-year-old White female majoring in art. She was in her second year at the college and did not have prior experience or training working with people with disabilities. Adrian and Piper supported Zion in art while Tenley supported Tori in her special education course.
Settings
We conducted the study at a liberal arts university with more than 9,000 students located in a rural area of a southeastern state in the United States. The university housed a postsecondary program as a continuation of high school for 18- to 22-year-old students. All students who attended this PSE program had graduated from high school but were still eligible for services under Individuals with Disabilities Education Act. The program had approximately 10 students with a disability, one program director, and many paid and volunteer peers each year. It offered both inclusive college courses and separate, self-contained recreational and music therapy courses over 4 years, along with paid and voluntary work experiences on- and off-campus. The PSE program served as the primary college experience for these students. All students in the PSE program lived locally with their families and came to campus daily.
Zion’s 2D art course met twice a week for 2 hr and included 17 students and one adjunct instructor. The students sat around a large conference table with enough space to work on art projects and spread out their materials and supplies. His peer partners sat on each side of him. After brief lectures, the instructor assigned multiweek drawing and/or painting projects followed by student presentations and peer critiques. The majority of class time was devoted to project work time.
Tori had 26 classmates and one adjunct instructor in her introductory to special education course, a 75-min course that took place twice a week. The classroom included five rows of tables. Tori sat beside her peer partner in the third row with her peer partner at the end of the table. For the majority of class time, the instructor lectured on the different disability categories. Occasionally, class sessions included small group activities.
The researchers, former special educators with data collection experience as teachers and research interventionists, collected all data in the college classrooms by sitting off to the side but close enough to hear and see the student and peer pairs. Peer training occurred at a convenient location for the peer. The researchers trained Adrian and Piper separately in a student lounge area in the art building, and the researchers trained Tenley in one of the researcher’s office in the education building.
Materials
During peer training, the researchers provided the peer partners with a handout on the goals, strategies for increasing communication, and ideas for conversation topics. During data collection, we used a data collection sheet and Invisible Clocks II (Time Now, 2020) that vibrated every minute to assist with the interval data recordings.
Data Collection
We collected data through direct classroom observations using partial interval recording. We divided the observation period into 1-min intervals and recorded student interactions and communication functions. We coded an interaction as any verbal or nonverbal communicative behavior (i.e., initiations or responses) produced by the student toward their peer partner. We defined an initiation as the student asking a question, making a comment, or producing a nonverbal behavior (e.g., raising a hand for high five) that evoked a response from the peer partner. Consequently, we defined a response as the student immediately communicating after the peer asked a question or made a comment through the use of verbal or nonverbal communication (e.g., head nod and thumbs up). When an interaction occurred, we also coded the communication function (i.e., expressing academic- or social-related information). We defined academic topics as discussing course content or assignments (i.e., art for Zion and special education for Tori) and social topics as any non-course-related topics (e.g., evening activities, job-related conversations, and sports). In addition, we coded if three or more turns took place during multiple consecutive interactions, our primary dependent measure. We defined three turns as three or more consecutive reciprocal exchanges of initiations and/or responses produced by the student. We coded a new interaction when a pause of 5 s or more occurred. At the beginning of each interval, we recorded the class format (large group, small group [2–8 students], independent work, no instruction, or gone from the classroom) and proximity of the student to their peer partner, other peers, and instructor (within 1 m).
The first author trained the second author on the data collection procedures by explaining the data collection form and definitions and then by watching videos of students socially interacting. They practiced collecting data until they reached 90% or above agreement. They watched three different videos (10–15 min in length) to achieve this criterion.
Research Design
We used a single-case multiple baseline design across student and peer pairs to evaluate the effect of peer training on student social interactions (Ledford & Gast, 2018). By using this design, we attempted to control for possible threats to the internal validity of the study. First, we controlled for history and maturation through the staggered introduction of the intervention across different student pairs. Each baseline condition included at least four sessions with a stable or decreasing pattern of data. After the first participant pair moved into the intervention condition and made gains, the second pair received the intervention if they had stable baseline data. This process continued until all participants received the intervention. We used three or more communicative turns as the primary dependent measure, although other dependent measures were collected. We were interested in expanding the student participants’ current communication skills through turn-taking as reciprocity is a measure of quality interactions (Carter et al., 2017). Second, we controlled for adaptation threats (i.e., impact of unfamiliar partners) by recruiting peer partners who already sat with and knew the student since the beginning of the semester to participate in the study. Third, the collection of interobserver and procedural reliability data strengthened the internal validity of the results. Finally, we demonstrated the external validity through the replications of the intervention effects across multiple student–peer pairs; however, more research will be needed in the future to expand the external validity.
This research design allowed us to evaluate the effect of peer training on social communication for postsecondary students with ID through visual analysis of the graphed data. Systematic visual analysis has been validated as a primary approach when analyzing results of single-case research (Horner et al., 2005). We examined changes in levels, trends, and stability between the baseline and intervention conditions (Ledford & Gast, 2018). In addition, we calculated Tau-U to estimate the intervention effects by taking into account the nonoverlapping data points and trends between baseline and intervention (Vannest & Ninci, 2015). Many researchers have reported that Tau-U is a more accurate effect size measure as it accounts for level changes across conditions and baseline trends (e.g., Parker et al., 2011; Rakap, 2015). We interpreted Tau-U as a small effect (<.20), moderate effect (.20–.60), large effect (.60–.80), or very large effect (>.80; Vannest & Ninci, 2015). To analyze findings from the social validity measures, we identified themes associated with the goals, procedures, and outcomes of the study across the perspectives of students and peer partners.
Procedures
Baseline
We conducted baseline observations of each student as they participated in typical activities in the college class during the entire class period. No instructions were provided to the students or peer partners; however, they were aware we were observing interactions from signing the consent forms at the start of the study (i.e., possible Hawthorne effect). We collected data on the student’s social communication behaviors with their peer partners (e.g., three or more turns, initiations and responses, and communication functions as social or academic) and the instructional format and proximity of the student with others using 1-min interval recordings. We collected baseline data for a minimum of four sessions showing a stable or contratherapeutic pattern. While collecting data for five sessions is best practice (Kratochwill et al., 2010), we only collected baseline data for four sessions with Zion in Tier 1, given the data stability and the number of remaining class sessions for the semester.
Peer training
Prior to the intervention condition, the researchers met with the peer partners individually for 15 to 20 min at a convenient location (i.e., student lounge and researcher’s office). We designed the training to discuss the purpose of the study, strategies to expand communication opportunities, ideas for conversational topics, and overall potential benefits. First, we stated that the purpose of the study was to expand the student’s communication and to increase their appropriate peer interactions. Second, we shared strategies that the peers could use to get the student talking more in class. They could greet each other at the beginning and end of class with “hi” and “bye.” The peer could prompt the student to respond if there is no response. The peer could ask questions to check for understanding and review material to promote academic learning. They could ask social questions at appropriate times throughout class and if the student did not respond, then the peer could give options. Third, we discussed academic and social topics to chat about. The researchers shared ideas (e.g., “Provide a definition for ____.” “What part do you want to review first?” “What did you do last night?” “What did you do at work today?”) and then asked the peer whether they had any other ideas or any questions. Finally, we explained that implementing these strategies would promote social relationships, classroom community membership, and academic learning. We provided the peer partner with a handout of everything discussed to serve as a visual reminder (available upon request).
After each intervention class session, the researcher walked out of class with the peer or emailed feedback to praise their strengths and provide suggestions for improvement. For example, one email stated, “Thanks for everything Tenley. You are doing great! Keep having social conversations at the beginning of class and during breaks. Also keep reviewing the class material and asking her questions to check for understanding.”
Intervention
Upon the completion of training, we asked each peer to implement the strategies in the college class with the student, and we provided specific feedback on their implementation of the strategies after each observation. We collected data in the same manner as during baseline sessions. After the peer implemented the targeted strategies and the student’s social communication showed a change in level, a second peer received training and the intervention condition began. This staggered introduction of the training and intervention continued until all peers implemented the targeted strategies.
Reliability
During at least 20% of the sessions in each condition (i.e., baseline and intervention), a secondary observer (either the first or the second author) collected reliability data independent of the primary data collector. We calculated interobserver agreement (IOA) using occurrence and non-occurrence agreement for the interactions (e.g., three or more turns, initiations, and responses) and point-by-point agreement for the context variables of class format and proximity. If IOA went below 80%, the researchers reviewed and clarified definitions of the dependent measures. In addition, we evaluated procedural reliability on the individual peer partner training sessions. The second author observed the training sessions and used a procedural checklist to calculate the percentage of steps completed by the first author. The procedural checklist included stating the purpose of the study, discussing the individual strategies to increase communication, sharing possible academic and social topic to discuss, describing the potential benefits, and asking for questions. The specific checklist is available upon request of the first author. A training session would be redelivered if the procedural reliability went below 95%.
Social validity
At the end of the study, we provided each participant with a survey to gain their perspectives and experience regarding the goal, procedures, and outcomes of the study. The student survey had five open-ended questions, whereas the peer survey included 10 questions. The program director read the survey to Zion and was available if Tori needed assistance. All students and peers wrote their own answers and completed the survey within 5 to 10 min.
Results
Social Interactions
Three or more turns
Figure 1 illustrates the percentage of intervals when the student with ID had three or more conversational turns with their peer partner. Zion’s baseline data with Adrian were low and stable with a mean of 0 (see Table 1 for mean and range scores). After peer training, there was an immediate increase to 7% and a gradual increase over the remaining intervention sessions demonstrating a very large effect with a Tau-U effect size of .96 (90% CI = [.34, 1.00]; p = .01). The overall mean for intervention sessions was 9%. For Tori, her baseline data were at a low level and variable with a mean of 3%. During the intervention, there was an immediate increase to 20% of the intervals with three or more turns, followed by a descending trend. Her Tau-U effect size was .57 (90% CI = [−.50, 1.00]; p = .13), showing a moderate effect, and the mean for intervention sessions was 9%. Zion did not have any interactions with three or more turns with Piper during baseline. However, each intervention session included at least one conversation with multiple exchanges resulting in a slightly higher level for a mean of 1% and a Tau-U effect size of 1.0 (90% CI = [.33, 1.00]; p = .14). Overall, the two students at least minimally increased the percentage of intervals with three or more turns, engaging in longer conversations after the three peers received individual training and implemented the strategies. Results of the visual analysis demonstrated a single replication across two students and a single replication across two peers for Zion.

Initiations and responses
Figure 2 shows the percentage of intervals when the student independently initiated an interaction or responded to a question or comment from their peer. Zion only initiated two interactions with Adrian with a low level and a slightly descending trend during baseline for a mean of 1%. During the intervention, there was a slight increase in level and positive change in trend with a mean of 3%. Zion initiated between one and four interactions in all intervention sessions except for one. He did respond to Adrian more often although his baseline data were variable with a mean of 13%. His intervention data showed a steady ascending trend with a mean of 23%.

Initiations and responses.
Tori seldom initiated a social interaction with Tenley during baseline (M = 1%), only two or three times in three out of seven sessions with an overall low level and a stable trend. However, her initiation data demonstrated a slightly higher level, a descending trend, and a small mean increase to 3% during intervention. For responses, her baseline data were low and variable with an ascending trend and a mean of 6%. During the intervention, she immediately increased performance to 30% in the first session and then the remaining sessions illustrated a descending trend. Her overall intervention mean was 14%.
Zion never initiated toward Piper and only responded once during baseline, showing very low and stable data paths. In intervention, he initiated once and responded between three and eight times during the three sessions. This resulted in positive changes in level and trend with means of 0.33% for initiations and 6% for responses.
Academic and social discussions
Figure 3 displays the percentage of intervals when the pairs were discussing academic and social topics. Interestingly, the data for academic topics follow a similar data path as student responses, and the data path for social topics is parallel to student initiations when comparing Figures 2 and 3. Across pairs, Zion and Piper talked more socially, whereas the other two pairs spoke more about academic content. Mean academic and social scores increased for all participants during the intervention. Zion and Adrian never spoke socially during baseline but communicated about social topics one or more times with a slightly ascending trend during the intervention. His baseline data for academic topics were variable, whereas his intervention data showed a steady incline. Socially, Tori only communicated once or twice with Tenley in baseline sessions, but she increased her social communication to two or four times during all intervention sessions except one illustrating a slightly higher level of data overall. Tori’s discussion of academic topics illustrated low and variable baseline data with a range of 1% to 15%. She did immediately increase to 26% during intervention. Though this was not maintained, her overall intervention data were at a higher level. Like Zion and Adrian, Zion and Piper did not communicate socially prior to peer training. After training, each intervention session included three to six social interactions, with an ascending trend. Likewise, they only had one academic interaction during baseline and two or three during all intervention sessions except one.

Contextual Variables
To assist with describing the variables within classrooms, we collected data on the instructional format and proximity of the student with their peer partner, other peers, and instructor at the beginning of each 1-min interval (see Table 1 for means and ranges of the percentage of intervals). The class format for Zion was primarily independent work during his 2D Art course. Because the classes primarily comprised work time to complete assigned art projects, students seldom stayed the entire 2 hr. Zion and his peer partners were typically one of the last students to leave. Over the 11 sessions, the average class time was 80 min. Zion was almost always in proximity to Adrian and Piper; occasionally, the peers walked around the room to get materials without Zion. Other peers were in proximity about half of the time, and his instructor was nearby approximately 30% of the intervals. Tori’s class, Introduction to Special Education, was mostly a large group lecture representing 88% and 86% of the intervals during baseline and intervention, respectively. All but four sessions (2, 3, 7, and 11) included some small group work time. She was almost always in proximity to her peer partner and other peers and never next to her instructor. Her average class time was 74 min over the 11 sessions. It is important to note these contextual variables as they play a part in the opportunities for social interactions in college courses.
Reliability
For each student and peer pair, we evaluated IOA during 27% of the classroom observations for each student participant. We calculated a mean IOA of 99% (range: 96%–100%) for three or more turns, 100% (range: 99%–100%) for student initiations, 99% (range: 97%–100%) for student responses, 99% (range: 96%–100%) for academic topics, and 100% (range: 100%–100%) for social topics across the three pairs. Furthermore, we had a mean IOA of 100% (range: 100%–100%) for classroom format and 99% (range: 97%–100%) for proximity with others.
To evaluate procedural reliability during the peer training sessions, we used a checklist to ensure that all training steps were completed. We evaluated procedural reliability during all three training sessions and had 100% reliability.
Social Validity
All participants completed the survey except for Piper, a peer partner, who did not return the survey. The students with ID stated they liked learning specific content in their courses and being with their peers in inclusive classrooms. Zion said talking with my peers “makes me happy,” while Tori said it “makes me feel more comfortable.” Both peers also noted that the students appeared to be more open and comfortable conversing as the study progressed.
The peer partners, who had no prior training on social communication, found the training to be beneficial and the strategies to be very rewarding as they saw improved communication skills and coursework of the students. They were impressed by the students’ increased conversational skills and their final projects and knowledge on quizzes. The peer partners said they would continue to use the communication strategies when working with other students with disabilities. One peer reported the training should remain the same length, whereas the other peer said the training could be a little longer to include more strategies. When asked about challenges, the peers said it was difficult to converse with the student when a lot of class time included the instructor lecturing or they felt nervous to naturally interact when observed by the researchers.
Discussion
Key Findings
Postsecondary programs at colleges and universities offer unique learning and social opportunities for students with disabilities to access advanced curricula, enhance interpersonal skills, and develop vocational competency. As adults with ID navigate college campus and life, their college peers have great potential to become natural supports inside and outside classrooms (Blumberg & Daley, 2009; Griffin, Mello et al., 2016; Jones & Goble, 2012). In our study, after peer training, the postsecondary students with ID increased their social interactions in all measures (i.e., three or more turns, initiations, responses, academic, and social topics) while continuing to learn and participate in class. These students carried on a conversation with multiple back and forth turns when asked questions or discussing a topic of interest with a peer. These results support the use of peer mentors to facilitate social and academic communication opportunities in rural postsecondary settings (Ryan, 2014; Workman & Green, 2019) and highlight the need for additional research to further expand the efficacy, as this study only included two participants with ID and we did not collect fidelity data on the peers’ implementation of the strategies after training.
Enhancing students’ communication, especially in the area of conversational turn-taking, is an important skill in further developing social relationships (Weiner, 2005). Reciprocal turn-taking in conversations is a complex skill that requires expressive and receptive competences, including listening, initiating and responding interchanges, yielding to the communication partner, and maintaining the topic or appropriately changing topics (Hay & Fielding-Barnsley, 2009). Data from this study illustrated an initial change in level after peer training although it was minimal for Zion and Piper. While we did not specifically code initiations and responses within three or more turns, it is likely that these increased conversational turns were a result of increased student responses, which had similar data patterns. This finding reaffirms the impact and importance of peer support on social communication (Chung et al., 2012b). We did not provide direct skill training to students with ID in this study. The students increased their social interactions when their peers provided more opportunities to respond to questions or comments.
During our training with college peer partners, we did not ask peers to prompt student initiations. Interestingly, we recorded an increase in independent initiations for both students, which seemed to be incidental or unplanned intervention effects among the increased interactions. These initiations may have been a random occurrence or a result of students feeling more comfortable or confident communicating and hearing many initiations modeled by their peer partners. With more interactions and peer initiations, the students may have also incidentally learned to initiate more often to form a social connection.
We also found that few interactions between the students and peers had a communication function related to social topics. Some student, peer, and classroom factors may have contributed to this outcome. First, Tori’s class format primarily consisted of lectures. In addition, Zion primarily focused his attention on his artwork during class. Moreover, the peer partners naturally knew when to discuss and initiate academic topics, but they might not have been as familiar with the students’ lives outside the classroom. Thus, we also noted similar data patterns for academic topics and student responses. However, for any missed communication opportunities, the peers could potentially benefit from more feedback or coaching on discussing social topics at the beginning and end of classes or ways to further expand academic conversations. Peers are a natural support in college environments and are usually willing to assist students with ID in further developing their academic and social skills (Carter et al., 2018; Hafner et al., 2011).
The instructional format of the class session seemed to impact the amount of natural communication opportunities provided. In our study, we observed some variations in students’ communicative behaviors prior to the intervention. For example, Zion engaged in few interactions during the first session of baseline (1% of intervals with responses and 75% of intervals in a large group). Conversely during the second baseline session, he responded during 26% of the intervals with 74% of the intervals making up independent work time. Similarly, when Tori’s class had small group time for 14% of the intervals during session six of baseline, she had a high response rate of 15%. The class format can be a variable when determining communication opportunities that influence student interactions (Chung et al., 2012a). This study exemplified that classes with less lecturing and more small group or independent work may be more ideal for promoting academic and social interactions.
Finally, this study showed that peers were interested in communicating with students having disabilities and benefited from, at minimum, a brief training in increasing their awareness of communication opportunities. The 15- to 20-min peer training sharing three specific strategies (greet, review academic content, and ask social questions) in this study resulted in increased academic and social communication of students with ID. Although fidelity of implementation data was not collected on the peers, these findings expand the literature and strengthen the evidence of using peer supports within higher education inclusive settings (Blumberg & Daley, 2009; Giust & Valle-Riestra, 2017; Griffin, Mello et al., 2016; Griffin, Wendel et al., 2016; Jones & Goble, 2012) and in particular rural PSE programs (Ryan, 2014; Workman & Green, 2019).
Limitations
We noted a few limitations with this study that could be improved with future replications. First, we only had two student participants because the PSE program only had a few students in inclusive college courses due to work schedule conflicts. Consequently, we trained two peers in separate sessions from Zion’s art course. Second, the data collection method of interval recording does not fully capture the complex nature of communication interactions and classroom contexts. For example, partial interval recordings often underestimate the occurrences of behavior; however, it is an appropriate and reliable recording procedure when collecting communication data in real time. Our anecdotal notes indicated that during many observed intervals in the intervention condition, both Zion and Tori had more than three conversational turns or initiated or responded multiple times during different interactions within one interval. Also, while Tori was never in proximity to her instructor at the beginning of an interval when we collected contextual data, they were occasionally next to each other when the instructor walked around during small group time. Third, there is the potential for the Hawthorne effect influencing our findings as the researchers were present to collect observational data, and their presence may have affected students’ and peers’ behaviors. Fourth, this study lacked peer data on the use of specific strategies and the fidelity of implementations of said strategies after peer training. Fifth, given the confines of a 15-week semester and data collection starting a few weeks into the semester, the researchers did not have time to collect five sessions of baseline data for all participant pairs. This time constraint also limited the researchers’ ability to make intervention modifications with the peers to further increase the student’s social communication or collect maintenance data to demonstrate the prolonged effect of the intervention and further analyze the variability in the data. Such challenges are common for researchers who conduct classroom-based research and attempt to establish experimental control within a set timeframe. Sixth, instructional formats such as lectures and the lack of peer socialization time limited social opportunities and resulted in natural variability within college courses.
Future Research
Ideas for future researchers include replicating this study with more student and peer participants, teaching peers naturalistic strategies, using eCoaching (in-ear coaching) to support peers or instructors, and collecting data across multiple courses, settings, or people (other peers and instructors). A systematic replication of this study with at least three different student–peer pairs would allow for more demonstrations of effect to strengthen the validity of the results. Fidelity data on the peers’ implementation of the strategies should also be collected in the future along with the students’ outcomes. While we taught peers to implement specific strategies to increase academic and social conversations in this study, students may benefit from their peers learning how to use modeling, mand-modeling, and time delay to promote communication. These naturalistic strategies are an evidence-based practice for students with ID (Browder et al., 2014; Courtade et al., 2015). In addition to providing didactic training with the peers, researchers might follow-up the training session with eCoaching in real time during the class period (Rock et al., 2012). The in-ear coach could identify communication opportunities and specifically tell the peer what to say or how to prompt the student to respond simultaneously. Peers could be cued to get the student conversing with other peers and their instructor too. Gilson and Carter (2016) argued the physical presence of a coach hindered the social opportunities and overall independence of college students with ID or autism spectrum disorder, so in-ear coaching was more effective. This eCoaching strategy could also be used with classroom instructors as they could benefit from training similar to that for the peer partners (Jones & Goble, 2012). To establish the external validity of the results, researchers could evaluate generalization in different college courses or settings (e.g., dining hall, recreational center, and student lounge) and with unfamiliar classmates and instructors. Also, additional data could be collected on the number of conversational turns taken or whether students responded to questions or comments from peer partners and other peers.
Implications for Practice
PSE programs provide opportunities for students with ID to be included in college courses and interact with peers without disabilities (Causton-Theoharis et al., 2009; Moore & Schelling, 2015). Overall, the outcomes of these programs can lead to improved employment options, healthy lifestyles, social connections, independence, and self-advocacy skills (Hart et al., 2006; Thoma et al., 2011). Of the surveyed PSE graduates, 91% reported being satisfied or very satisfied with their social life (Grigal et al., 2018). One component of a fulfilled social life comes from acquiring communication skills that can lead to enhanced social relationships. Communication is an important skill and an essential part of life and social interactions. Although more data are needed to corroborate the confidence of the results of this study, its findings showed how one short training on specific strategies for peer partners can result in students with ID taking more conversational turns. Reciprocal turn-taking can expand the communication interactions of students with ID and potentially forges social relationships. As these postsecondary students live in a rural area, developing social connections with peers on campus is even more important as socialization with friends while in their home community may not always be feasible. The ultimate goal for social communication and peer interaction interventions is to expand and diversify students’ social networks, which can lead to enhanced social capital and more future employment opportunities (Eisenman et al., 2013). Furthermore, the enhanced communication skills of students with ID can potentially assist in addressing the challenges when living in rural communities. Students may feel more comfortable and competent in communicating their needs to secure transportation, maintain employment, connect with friends, self-advocate, and locate available resources (Love & Mock, 2019).
PSE programs with trained peers also provide models of acceptable social communication skills that students with ID can imitate and replicate (Hafner et al., 2011; Jones & Goble, 2012). In this study, it can be implied that students increased their percentage of intervals independently initiating toward their peer partners as their communicative responses increased. It is likely that with more opportunities to communicate with a familiar individual, student initiations will continue to increase. In addition, educators should consider matching the class format to the communication needs of students with ID in courses that interest them. Courses incorporating time for small group activities provide natural opportunities for cooperative communication. Similarly, courses designed to include independent work time, such as 2D Art, typically promote collaboration with peers to brainstorm and critique ideas. PSE programs should be designed to purposefully enhance both academic outcomes and social interactions of students with disabilities through the use of trained peer supports. Peer supports are critical in the successful inclusion of students with ID on rural college campuses (Griffin, Mello et al., 2016).
