Abstract
This study examined the protective effect of perceived peer support on involvement in work experiences in a sample of 366 young women receiving special education services in 26 high schools. Career self-efficacy and career outcome expectations are well-established predictors of behaviors aimed at achieving career goals, such as obtaining work experiences. Hence, we also evaluated their role as mediators of the hypothesized effect of perceived peer support on work experiences. Regression analyses (accounting for clustering within schools) revealed that perceived peer support had an indirect effect on work experiences, with the effect being channeled through career self-efficacy, but not through career outcome expectations. Although perceived peer support was significantly associated with career self-efficacy and career outcome expectations, only career self-efficacy predicted work experiences at follow-up. Our findings suggest that perceived peer support, a relatively malleable factor, can promote career self-efficacy and career outcomes for this population.
Keywords
Decades of education policy have focused on improving postschool outcomes for youth with disabilities, particularly in the area of transition to employment. However, youth with disabilities continue to experience lower rates of postschool employment and significantly lower wages in comparison to their same-age peers without disabilities (Butterworth & Migliore, 2015; Newman et al., 2011). Within this broad category, young women with disabilities face unique barriers to securing and maintaining postschool employment (Lindsay et al., 2017). Compared to their male peers, females with disabilities are more likely to be employed part-time, earn lower wages, and are less likely to work in high skill/high wage jobs once they leave high school (Doren et al., 2011). The persistence of these inequities over time suggests that women with disabilities are less likely to escape poverty through employment than men (Berlan & Harwood, 2018; Mwachofi et al., 2009). Identification of malleable protective factors that can be promoted prior to high school graduation could be critical in ensuring equal access to regular income and employment opportunities.
Engaging in paid employment or work experience can be a robust in-school predictor of postschool employment outcomes. Several studies including participants with a range of disabilities have found that those who had paid or unpaid work experience during high school were more likely to be employed after graduating from high school (e.g., Carter et al., 2012; McDonnall, 2011; McDonnall & O’Mally, 2012; Wagner et al., 2014). This effect remains significant even after accounting for participation in a “transition to employment” program (Dong et al., 2016), suggesting that early work experiences can have a unique effect on postschool employment outcomes. Early work experiences can also serve to increase student motivation to work toward a career, increase student awareness of careers and job skills necessary to be successful at work, and strategies for requesting accommodations at school and work (Burgstahler & Bellman, 2005). Despite the importance of work experience, recent data from the National Longitudinal Transition Study 2012 indicate that nearly 60% of high school students with disability have not had a recent (in the last year) paid work experience (Lipscomb et al., 2017). Identifying ways to promote early work experiences among young women with disabilities can inform strategies to better support the needs of this population and better prepare them for successful postschool employment, thereby closing the employment gap between male and female youth with disabilities.
Social Cognitive Career Theory (SCCT)
We utilized SCCT as a guiding framework for formulating our research questions (S. D. Brown & Lent, 2005). Based on Bandura’s social cognitive principles, SCCT is an integrated career development framework that describes how dynamic and situation-specific aspects of people (e.g., self-views, future expectations, behaviors) and their environments (e.g., social support, employment opportunities) jointly predict occupational and academic interests, choices, and attainment of career goals (S. D. Brown & Lent, 2005). It specifically focuses on the interplay between three key constructs: (a) self-efficacy, or the confidence that one will be successful in completing a specific task or set of tasks; (b) outcome expectations, which are the results one expects to achieve for putting forth the effort to complete a task; and (c) goals, or one’s resolve to obtain a particular outcome. These goals are expected to guide educational and career behavior over time (Lent et al., 1999).
Consistent with social learning principles, self-efficacy beliefs and outcome expectations can be shaped by observing others (including peers) and, verbal encouragement or discouragement from the beliefs and opinions of others, and positive or negative mood states (Bandura, 1986). As such, perceived peer support during high school could play a significant role in shaping self-efficacy beliefs and outcome expectations related to career outcomes. These beliefs and expectations in turn could influence educational and career goals and behaviors. Nevertheless, the effect of perceived peer support on career self-efficacy and outcome expectations has not been previously explored for young women with disabilities. This is a critical gap as perceived peer support is a highly malleable construct that has been successfully promoted in interventions with other adolescent populations (e.g., Hossfeld, 2008; Schumacher, 2014).
Peer Support and Career Development
The influence of peer relationships on the career development of young women with disabilities warrants attention as one of the hallmarks of youth with high incidence disabilities (e.g., specific learning disability, intellectual disability, emotional and behavioral disorders, and attention deficit/hyperactivity disorders) are social skills deficits (Gresham et al., 2001). When compared to their peers without disabilities, youth with disabilities report having fewer friends, lower quality friendships (e.g., less likely to communicate regularly or get together outside of school), and more likelihood of being bullied (Lipscomb et al, 2017). Additionally, youth with disabilities are more likely to report feeling powerless and alienated (M. R. Brown et al., 2003), suggesting that students with disabilities may have less access to the protective factors of friendship including self-esteem and a sense of belonging (Salmon, 2013).
The importance of peers during adolescence is supported by extensive literature highlighting the positive association of prosocial relationships with peers and adolescent identity development (Rageliene, 2016). Felsmen and Bluestein (1999) highlighted the influence of peer relationships on career development tasks in late adolescence, reporting that adolescents with greater attachment to peers reported higher levels of career exploration (e.g., investigated career possibilities, obtained information on specific jobs) and made greater progress in committing to careers. In contrast, students reporting lower levels of peer support experience sharper declines in sense of school belonging and valuing of learning and declines in participation in extracurricular activities including volunteering, as compared to their counterparts who report higher levels of peer support (Wang & Eccles, 2012). Some research also suggests that girls tend to have stronger peer attachments than boys (Gorrese & Ruggieri, 2012), making it even more relevant to examine the effects of perceived peer support among young women with disabilities.
Purpose of the Study
The application of SCCT to the transition from school to work (Lent et al., 1999) highlights interrelated processes whereby students acquire self-efficacy and outcome expectations throughout childhood and adolescence. Self-efficacy and outcome expectations influence academic and career interests, career goals, and actions aimed at attaining goals. These processes are iterative and ongoing, throughout childhood and adolescence. During the elementary and middle school years, prominent tasks include acquiring self-efficacy and outcome expectations, developing career-related interests, and forming early career goals although these tasks are refined throughout high school and beyond (Lent et al., 1999).
One aspect of the SCCT model that has received less research attention is the effect of contextual variables, including environmental inputs such as peer support, on these processes. The SCCT model posits that career interests are more likely to develop into goals and goals into actions in supportive environments. In contrast, nonsupportive or hostile environments can interfere with these processes (Lent, 2005). Given what we know about the importance of peers during adolescence (Rageliene, 2016), it is important to continue to explore the role of peer influence on adolescent’s career development processes, including participating in work experience, which is a robust predictor of future employment. Therefore, the purpose of this study was to examine the effects of perceived peer support on recent work experiences of young women with disabilities. Our research questions were as follows: Does perceived peer support at school predict greater likelihood of paid or unpaid work experience in a sample of high-school aged young women with disabilities? Do career self-efficacy and career outcome expectations mediate the potential effect of perceived peer support at school on work experience?
Guided by the SCCT framework, we hypothesized that perceived peer support would predict career self-efficacy and career outcome expectations, which would in turn predict behaviors toward attaining these goals, such as engaging in work experiences during school. Given that efficacy beliefs and outcome expectations are more proximal predictors, we expected perceived peer support to influence work experience through these mediators and not as a direct effect.
Method
Study Procedures
The current study used data from 366 participants enrolled in a randomized trial evaluating the efficacy of an intervention designed to improve career outcomes for young women in high school receiving special education services. Students were recruited from 26 public high schools in the Northwestern region of the United States. Special education teachers and school counselors at each school were asked to identify a sample of young women in their schools to participate in the study based on the following inclusion criteria: (1) identify as female, (2) currently enrolled in Grades 9 through 12 in a participating high school, and (3) determined eligible for special education services with a high incidence disability including learning disability, other health impairment (including attention deficit hyperactivity disorder/attention deficit disorder), autism spectrum disorder, speech/language disability, and emotional disability.
Schools in the larger study were randomly assigned to intervention and control conditions using propensity score matching procedures. A total of 153 participants from 13 schools were randomized to the intervention condition and 213 participants from 13 schools were randomized to the control condition. Participants in the intervention condition received the Paths 2 the Future intervention, a 75-lesson career development curriculum designed to promote positive career development outcomes for young women with disabilities, completed over 2–9 months depending on the school schedule (e.g., daily class vs. block schedule). The curriculum is divided into four modules: (a) self-awareness, (b) disability knowledge, (c) gender identity, and (d) career and college readiness. Participants in the control condition received “business as usual” career and transition services within their high school. For additional details about the intervention or study design, see (Lindstrom et al., 2019). Parent consent and student assent were obtained prior to the study onset.
Students in both control and intervention groups completed a web-based survey at four time points: (a) preintervention (T1), (b) midway through the academic year (for schools implementing a full year schedule; T2), (c) postintervention (T3), and (d) 6-month follow-up (T4). Students took between 15 and 60 min to complete the surveys, and the research team members were available to answer any questions the students had about the survey. At T1, teachers provided data on the student’s diagnosis qualifying them to receive special education services as well as information on academic, family, health, work, and other barriers that often limit educational attainment and may influence postschool outcomes. The present analyses were conducted using T1 and T3 data (for outcome variable only).
Sample
The study sample (N = 366; mean baseline age = 16.54 ± 1.12 years) included 61% non-Hispanic White and 19% Latina youth, enrolled in Grades 9 (14%), 10 (34%), 11 (30%), and 12 (22%). Most participants were receiving special education services under the specific learning disability (55.2%) and other health impairment (14.8%) categories. For each participant, teachers were asked to indicate whether the student was experiencing any additional risk factors/barriers in five areas including academics, family or living, work, at-risk behaviors, and health challenges. Most common teacher-reported barriers included difficult family circumstances (43.7%), mental health issues (42.6%), chronic absences (27.6%), no prior work or volunteer experience (25.1%), or behind in completing credits toward graduation (16.4%). According to teacher reports, 22.7% of the sample did not experience any barriers while 53.6% experienced more than one barrier (see Tables 1 and 2 for additional demographic data on all participants.)

Measures
Work experience (T3)
Work experience was assessed using the following Y/N question: “Have you had any work experiences in the past 6 months?” We used the T3 assessment of work experience to ensure that the outcome did not temporally precede the predictor variables. Forty-two percent of the baseline sample (n = 152) indicated involvement in work experience at T3. There was 14% loss of participants at T3.
Perceived peer support (T1)
The Peer Support for Learning subscale of the Student Engagement Instrument (Appleton et al., 2006) was used to measure perceived peer support at school (e.g., “Other students here like me the way I am,” “Students here respect what I have to say”). Responses for the six items ranged from 1 (strongly disagree) to 4 (strongly agree). The items were averaged to create a single scale score at T1 (α = .90; mean = 17.52; standard deviation [SD] = 3.66). Appleton et al. (2006) reported a Cronbach’s α of .82 with a sample of high school freshman. An α coefficient of .90 was obtained in the pilot sample (Lindstrom et al., 2013) and a study with young women in high school identified with a special education label or multiple risk factors (Doren & Kang, 2015).
Career self-efficacy (T1)
An adapted version of the Vocational Self-Efficacy Scale (McWhirter et al., 2000) used in the pilot study (Lindstrom et al., 2013) was used in the current study to assess confidence in completing tasks related to job preparation skills, time management, and goal setting. In order to increase developmental and content appropriateness for the study population, eight items focused on specific careers or skills needed to pursue specific careers were eliminated, reducing the number of items from 37 to 29. The scale range was also reduced from nine to five choices. Participants rated their level of confidence on 29 items related to job preparation skills, time management, and goal setting (e.g., “state my general career interests [areas of interest],” “find out the education requirements for a job”) on a scale ranging from 1 (no confidence at all) to 5 (complete confidence). Items were averaged to create a composite score at T1 (α = .97; mean = 94.66; SD = 23.41). McWhirter et al. (2000) reported a Cronbach’s α of .97 with a sample of high school sophomores. An α coefficient of .94 was obtained with the adapted scale in the pilot study (Lindstrom et al., 2013) and an α coefficient of .88 was obtained in a study with young women in high school identified with a special education label or multiple risk factors (Doren & Kang, 2015).
Career outcome expectations (T1)
We used the six-item Vocational Outcome Expectations Scale (McWhirter et al., 2000) to measure adolescents’ level of agreement with questions about career expectations, satisfaction, and feelings about the future (e.g., “my career planning will lead to a satisfying career for me,” “I have control over my career decisions”). Responses ranged from 1 (strongly disagree) to 4 (strongly agree). The six items were averaged to create a composite score (α = .88; mean = 18.91; SD = 3.20). McWhirter et al. (2000) reported a Cronbach’s α of .83 with a sample of high school sophomores. An α coefficient of .88 was obtained in the pilot sample and a study with young women in high school identified with a special education label or multiple risk factors (Doren & Kang, 2015).
Covariates
Age, race, ethnicity, disability type (learning disability vs. other), and teacher-reported barriers to academic success and future employment were included as covariates. Students were asked to self-report their birth date and race ethnicity. Teachers were asked to report the primary disability category under which each student was receiving special education services. Since the majority of the students (55%) qualified under the learning disability category, we categorized this variable as learning disability versus other. Teachers also reported risk factors or barriers to academic success or future employment experienced by each student from a list of 18 items in five areas including academics, work, difficult family/living circumstances, at-risk behaviors, and health challenges. A total risk variable was used (M = 2.29, SD = 2.15; range = 0–10). Controlling for these variables is important as employment rates for high school students with disabilities have been found to vary according to age, race/ethnicity, and disability type (Wagner et al., 2003). Additionally, we controlled for intervention versus control group assignment and days between T1 and T3 data collection (M = 166.10; SD = 71.82) because the outcome variable was assessed at T3.
Analytic Method
Given the binary nature of our outcome variable, we used logistic regression analyses to test our models. Clustering of students within schools was accounted for in the analyses. We used a Bayesian estimator in Mplus to estimate the asymmetric confidence intervals of the direct and indirect effects. Descriptive analyses were conducted in STATA Version 14.0, and path analyses were conducted using MPlus, with robust estimation procedures. Missing data were handled using full information maximum likelihood in Mplus v8.
Results
Sample Descriptives
At T3, nearly half of the sample (48%) reported having engaged in a paid/unpaid work experience in the past 6 months. Work experience was positively related to age and career self-efficacy. Perceived peer support was positively related to career outcome expectations and career self-efficacy. Correlations, means, and SDs of study variables can be found in Table 3.

Logistic Regression Models
The direct effect of perceived peer support on work experience at T3 was not significant, B (SE) = −.25 (.21), p = .23. Perceived peer support was however significantly related to career self-efficacy, B (SE) = .29 (.09), p = .002 (95% CI [0.16, 0.42]), and career outcome expectations, B (SE) = .24 (.05), p < .001 (95% CI [0.15, 0.32])——the two proposed mediators in our model (see Figure 1 for standardized estimates). In turn, career self-efficacy was a significant predictor of work experiences at T3, B (SE) = .44 (.20), p = .03 (95% CI [0.07, 0.54]). However, career outcome expectations were not significantly related to engagement in work experience, B (SE) = −.01 (.24), p = .96. The indirect effect of perceived peer support on work experience was channeled through career self-efficacy, B (SE) = .08 (.04), 95% CI [0.02, 0.18]. Of the controls, age, B (SE) = .27 (.11), p = .01, and group assignment, B (SE) = .57 (.25), p = .02, had significant effects on work experience, such that participants who were older as well as those assigned to the intervention group were more likely to report work experiences at T3.

Discussion
This study examined the role of perceived peer support in predicting work experiences in sample of young women with disabilities enrolled in high school. We found that perceived peer support had an indirect effect on work experiences that was channeled through career self-efficacy. Specifically, participants who reported high levels of perceived peer support also had higher ratings of career self-efficacy which in turn was a significant predictor of having engaged in paid/unpaid work experience (at T3). Perceived peer support was also positively related to career outcome expectations, but expectations were not predictive of work experience in our sample.
The association between perceived peer support and career self-efficacy is consistent with previous research identifying peers as influential social agents for adolescent career development (Ali et al., 2005). Other studies have similarly found that adolescents’ career expectations tend to be more strongly influenced by their same-sex peers, likely due to vicarious learning experiences from similar role models (Paa & McWhirter, 2000). In a recent meta-analysis examining associations between career self-efficacy and nine predictors commonly used across studies (gender, age, race, self-esteem, vocational identity, career barriers, peer support, career outcome expectations, and career indecision), Choi and colleagues (2012) found that peer support significantly and positively predicted career self-efficacy in a sample of students aged 10–26 (rc = .41, p < .001; effect size = .35). Given these consistent findings, it appears that young women see their peers as important and accessible role models and sources of support and information related to career development. This finding supports Lent’s (2005) assertion that while self-beliefs are embedded within a complex web of systems, including cultural and structural factors that serve as barriers to career development for all women, there are “developmental and preventative routes for redressing socially imposed limitations” (Lent, 2005, p. 115). These routes include learning environments, where women’s career development can be constricted or expanded depending upon their access to efficacy information including social encouragement.
Also consistent with the SCCT model and prior research, we found that perceived peer support was positively associated with career outcome expectations. For example, using a sample of urban high school youth, Kenny et al. (2003) found that students who reported higher levels of social support also reported higher levels of career outcome expectations. Our findings show that perceived social support can have similar effects on career outcome expectations among young women with disabilities in high school. Contrary to our predictions however, in this study sample, career outcome expectations did not predict engagement in work experiences during high school. According to SCCT (Lent, 2005), although both self-efficacy and outcome expectations influence career-related behaviors, self-efficacy may be more influential in situations that require complex skills or that are perceived as difficult courses of action. For example, a young woman could think that obtaining work experience could lead to desired outcomes or payoffs but avoid action necessary to obtain a work experience if she does not believe she has the ability to successful obtain a work experience (i.e., low self-efficacy). Also, while in high school, there are significant differences in the types of employment reported by females and males with disabilities. Young women with disabilities are more likely to report working at informal jobs (for unlicensed employers) with the most common type of job being personal care, including babysitting (Wagner et al., 2003). It could be that young women in this study did not link their expectation of long-term success in their chosen career to the work experiences most commonly available to them in high school.
To our knowledge, this is the first study to assess the effect of perceived peer support on work experience using a sample of high school-age young women with disabilities. In a cross-sectional sample of 147 undergraduate students, Felsman and Bluestein (1999) found that students who reported a greater attachment and closeness to their peers also reported higher levels of commitment to pursuing a chosen career and engaging in more career exploration activities. While we found a significant indirect effect, we did not observe a direct effect of perceived peer support on work experiences. Numerous factors can influence a youth’s decision to work including parent support (Lindsey et al., 2017) and availability of school-based work experiences and job placement services (Carter et al., 2010). Further, given the relatively young age of our sample (as compared to Felsman & Bluestein, 1999), many young women might not have had the opportunity to engage in work experiences, which could have impeded our ability to detect stronger associations with perceived peer support.
Considerations for Practice
Overall, our findings suggest that perceived peer support at school can improve the odds of engaging in work experience for young women with disabilities in high school. The effectiveness of school-based interventions that enhance connectedness among all students could be examined for their effectiveness for helping to build support networks for young women with disabilities in particular and increase their perceptions of peer support. Interventions can be implemented within a multitiered framework of service delivery (Grapin et al., 2016). At the universal or school-wide level, social and emotional learning (SEL) program interventions are typically aimed at enhancing school climate and promoting positive relationships among the school community (Demaray & Malecki, 2014). Student development of cognitive, affective, and behavioral competencies through SEL programs have been shown to increase student prosocial behaviors, reduce problem behaviors, and improve both academic performance and peer relationships (Durlak et al., 2011).
Past efforts aimed at improving peer relationships of students with disabilities have focused on social skills training and increasing interactions with peers without disabilities. For example, several peer-mediated interventions have been found to be effective at increasing social interactions for students receiving services under the autism and intellectual disability categories in inclusive settings including peer tutoring, peer partner programs, and peer support arrangements (Carter et al., 2011). In peer-mediated interventions, a student without a disability is usually trained to work with a student with a disability in a general education classroom. Carter et al. (2011) partnered students with an interventionist who helped students to identify strategies to support focal students during different portions of class (i.e., at the beginning, during lectures or whole group instruction, during small group activities, during independent work, and at the end of class). All students in the intervention reported experiencing immediate and pronounced increases in social interactions. Other interventions aimed to increase peer networks of students with ASD have also resulted in participants increasing peer interactions and social engagement (Hochman et al., 2015).
In addition to focusing on social skill development and fostering friendships with peers without disabilities, high school transition programs could include an emphasis on fostering connections with peers with disabilities. People are more likely to form friendships with people who are similar to them (McPherson et al., 2001), and there is no exception for people with disabilities who may find it easier to connect with others who can relate to experiences associated with having a disability (Fulford & Cobigo, 2018). Additionally, some youth have indicated sensing power dynamic differentials in friendship with youth without disabilities in which they feel more vulnerable to exploitation or teasing and for this reason prefer friendships with others with similar disabilities to which they can relate (Mason et al., 2013). Most efforts at promoting social relationships for youth with disabilities have focused on integration and development of friendships with other youth without disabilities (Fulford & Cobigo, 2018), yet promoting friendships with other peers with disabilities would also be beneficial as these youth have expressed the importance of reciprocal friendships that promote a sense of belonging and social connectedness (Mahar et al., 2013; Western et al., 2007).
Peers could also participate in employment or career interventions to help facilitate career awareness and information-gathering processes (Paa & McWhirter, 2000) or to enhance self-efficacy (Lindsey et al., 2017). For example, Lindsey et al. (2017) are currently examining the effectiveness of online peer support and mentoring program for youth with physical disabilities aimed at improving self-determination, career maturity, and social supports. Given documented gender differences in peer attachment (Gorrese & Ruggieri, 2012), these may be especially important strategies for young women with disabilities.
Limitations and Future Research
There are several limitations to our study that should be considered. First, we did not differentiate between the type of work experience (paid/unpaid), or the quality and duration of work experience, which would be helpful in better understanding the role of perceived peer support in promoting work experiences. Variability in work experience is associated with long-term career outcomes. For example, paid employment/work experiences are associated with the likelihood of postschool employment (Mazzotti et al., 2015), and young women are more likely to enter personal care and service occupations versus nontraditional careers such as installation, mechanics, maintenance, and repair (Newman et al., 2011). Second, we did not account for how students found employment, that is, if they actively searched for it (reflecting greater career self-efficacy) or if they were placed into specific opportunities by school staff or family members.
Also, contrary to our expectations, career outcome expectations did not predict work experience. Future research should further explore the function or motivation young women have for seeking employment experiences during high school in order to better assess how or if this is connected to career expectations. Work experience is an important outcome that is predictive of long-term employment trajectories, health, and well-being, but it may not be sufficient to fully understand how variables assessed in this study impact broader career exploration and commitment outcomes. As compared to prior cross-sectional research (e.g., Felsman & Bluestein, 1999), we used a longitudinal design to predict future work experiences, which increases the relevance of our findings and also might explain why our associations were different as compared to prior studies.
Scientific or Scholarly Significance of the Study or Work
Despite the unique and persistent barriers faced by young women with disabilities in securing postschool employment, very few studies have focused on identifying malleable factors that are associated with improved career outcomes. Work experience gained during high school is one of the most robust predictors of postschool employment, yet young women are less likely than their male peers with disabilities to obtain this experience. This study adds to the sparse body of literature by identifying the unique role of perceived peer support at school in promoting career self-efficacy and work experiences among young women with disabilities. These findings, if replicated in future work, can have important implications for the integration of perceived peer support interventions into transitioning programming and curricula, particularly for young women with disabilities.
