PERSISTENCE IN POSTSECONDARY EDUCATION Postsecondary Education Persistence of Adolescents with Specific Learning Disabilities or Emotional-Behavior Disorders 1 PERSISTENCE IN POSTSECONDARY EDUCATION 2 Abstract While experiences of students with disabilities transitioning from high school to college have been well documented, the influence exerted by selected factors on these experiences is less well understood. Using data from the Education Longitudinal Study of 2002, the influence of selected risk and resilience factors on the short-term postsecondary educational outcomes, i.e., persistence, of adolescents with specific learning disabilities or emotional-behavior disorders was examined. A logistic model revealed group differences between individuals with disabilities and peers without disabilities. All selected risk and resilience factors significantly predicted educational persistence. No significant differences were observed between adolescents with specific learning disabilities or emotional-behavior disorders, but three factors—grade point average, socioeconomic status, and number of friends having plans to attend a 4-year college—were significant predictors of educational persistence for adolescents with disabilities. Implications of these findings are discussed. Keywords: postsecondary educational outcomes, risk and resilience framework, highincidence disabilities PERSISTENCE IN POSTSECONDARY EDUCATION 3 Postsecondary Education Persistence of Adolescents with Specific Learning Disabilities or Emotional-Behavior Disorders An increasing number of adolescents with disabilities have pursued postsecondary education in recent years (Getzel, 2008; Newman, Wagner, Cameto, & Knokey, 2009). However, individuals with specific learning disabilities or emotional-behavior disorders enroll in college and postsecondary training at rates far below those of the general population without disabilities (Wagner, Newman, Cameto, Garza, & Levine, 2005). Moreover, students with disabilities are less likely to maintain full-time status resulting in longer periods needed to complete a degree (Wessel, Jones, Markle, & Westfall, 2009), and more likely to drop out of postsecondary education (Murray, Goldstein, Nourse, & Edgar, 2000). Although a few comprehensive studies have been conducted on the transition of adolescents with disabilities from school to postsecondary education and work (e.g., Blackorby & Wagner, 1996; Newman et al., 2009; Wagner et al., 2005), relatively little is known about how risk and resilience factors contribute to the persistence of students with disabilities in postsecondary education. Our study focused on adolescents with specific learning disabilities or emotional-behavior disorders because of the many similarities these adolescents share, including overlap among the impact of disability on academic performance, work preparation, and career attainment (Dietz & Montague, 2006; Kaplan, Dewey, Crawford, & Wilson, 2001; Hallahan, Kauffman, & Pullen, 2012). Even so, Sabornie (Sabornie, Cullinan, Osborne, & Brock, 2005; Sabornie, Evans, & Cullinan, 2006) identified important differences in the cognitive and behavioral characteristics of these groups. For example, adolescents with specific learning disabilities exhibit higher cognitive abilities and higher academic achievement. Adolescents with emotional-behavioral disorders were more likely to face arrest, incarceration, or probation-parole violation (Newman et al., PERSISTENCE IN POSTSECONDARY EDUCATION 4 2009). The decision to examine adolescents with these disabilities in the same analysis was based on the similarity in characteristics and the common challenges faced as they prepare for and transition from school to postsecondary education and work (Gregg, 2009). Examining how adolescents with disabilities experience and cope with academic- and career-related issues can facilitate a better understanding of how career theories and interventions might be used to explain and promote career behavior, choice, and attainment for these individuals. Persistence in Postsecondary Education Postsecondary education plays a significant role for individuals with disabilities aspiring to career opportunities that cannot be attained with a high school degree (Lindstrom, Doren, & Miesch, 2011). Employment projections in the United States provide compelling evidence on the increasing importance of postsecondary education. Occupations requiring at least some type of postsecondary education for entry are expected to grow at quicker rates than other aspects of the workforce, while occupations requiring a high school degree or less will grow more slow (Lockard & Wolf, 2012). While a majority of jobs held by individuals with disabilities are semiskilled and part-time (Barkley, 2006), individuals with disabilities who earn postsecondary degrees show comparable work outcomes (e.g., employment status, benefits, income) to individuals without disabilities (Madaus, 2006). One positive indicator used to represent success in pursuing a postsecondary education degree is the concept of persistence. Berger and Lyon (2005) defined persistence as “the desire and action of a student to stay within the system of higher education” (p. 7). Students are more likely to enroll and persist in their degree program when engaged in the institution both academically and socially. Much of the work on persistence of students in postsecondary PERSISTENCE IN POSTSECONDARY EDUCATION education has focused on individual and college factors (Tinto, 1987, 1992). Mamiseishvili and Koch (2011) found that women and African American college students were more likely than men and White students to persist. Students who held positive outcome expectations about attaining a higher degree were also more likely to persist. Seo, Abbott, and Hawkins (2008) reported that adolescents with learning disabilities had significantly lower postsecondary school enrollments at age 21 than those without disabilities. Adolescents with disabilities from middle or high socioeconomic status (SES) families had higher postsecondary education enrollments than those with disabilities from low SES families (Wagner et al., 2005). Kortering, Braziel, and McClannon (2010) reported that students with learning disabilities were more likely to have lower educational and occupational aspirations than those without disabilities. Factors influencing these lowered rates of enrollment and persistence of students with disabilities in college are not clear. Conceptual Considerations for Risk and Resilience Factors Use of a risk-resilience framework offers researchers a balanced approach to understanding the outcomes of individuals with disabilities by stressing individual strengths and limitations, rather than an emphasis on limitations imposed by the presence of disability. Risk factors increase the likelihood that barriers or constraints exist that limit individual plans or activity, while resilience factors are those processes that reduce the risk or increase the probability of successful outcomes (Gregg, 2009; Murray, 2003). The presence of disability increases the possibility that adolescents will experience risk (Morrison & Cosden, 1997), while the nature of disability presents both common and unique career needs, experiences, and potential, as well as susceptibility to career-related risks. Career-related barriers associated with disability include social stigma, employment discrimination, inadequate vocational training and preparation, poor 5 PERSISTENCE IN POSTSECONDARY EDUCATION 6 self-efficacy, and lower or restricted occupational aspirations (Fabian & Liesener, 2005). Resilience factors can be divided into internal and external influences. Internal resilience factors include positive temperament, recognition of one’s disability, accommodation strategies, and knowledge of ways to be proactive and advocate for one’s self (Gregg, 2009; Murray, 2003). Disability identity may have a bearing on the career behavior of adolescents with disabilities by decreasing engagement with others (Mpofu & Harley, 2006). Other internal factors pertinent to educational persistence include an individual’s educational expectations and academic achievement (Murray, 2003). Family factors such as SES, family composition, parent-child discussions about work and education, and parents' educational expectations may also influence educational persistence. External resilience factors support individuals in their education- and work-related decisionmaking. The presence of a supportive adult appears to be one of the strongest resilience factors for individuals with learning disabilities (Goldberg, Higgins, Raskind, & Herman, 2003). Connections to supportive and helpful people (Reiff, Gerber, & Ginsberg, 1997), sustained emotional support from parents (Cosden, Brown, & Elliott, 2002), and positive parent-child interactions (Wong, 2003) also appear related to the potential of success for individuals with disabilities. It is critical that high school students with disabilities are knowledgeable of the Americans with Disabilities Act, realities of the workplace, and importance of self-determination (Madaus, Gerber, & Price, 2008). Outcomes for individuals with learning disabilities “reflect a combination of protective and risk factors, some of which are internal, whereas others are external to the individual” (Morrison & Cosden, 1997, p. 56). Since risk and resilience factors may influence the career behavior and postsecondary educational outcomes of adolescents with specific learning disabilities or emotional-behavior PERSISTENCE IN POSTSECONDARY EDUCATION 7 disorders, our understanding incorporated the work of both career theorists (e.g., Lent, Brown, & Hackett, 1994) and disability researchers (e.g., Murray, 2003; Wong, 2003). Another aspect to consider was the issue of outcomes. The unique interplay of risk and reliance factors will result in widely varied outcomes ranging from successful employment or unemployment, enrollment in a postsecondary academic or vocational programs, dropping out of school or successful completion of a postsecondary degree, job difficulties, job (dis)satisfaction, and life (dis)satisfaction (Barkley, 2006; Reiff, Gerber, & Ginsberg, 1997). The question of how to incorporate risk-resilience factors to understand the persistence of young people with specific learning disabilities or emotional-behavior disorders in postsecondary education deserves attention. Purpose Our analysis examined the influence of selected risk-resilience factors on college persistence for adolescents with (or without) specific learning disabilities or emotional-behavior disorders. The outcome, persistence, was a conceptualized as a dichotomous variable based on the pursuit or lack of pursuit of postsecondary education measured two years after high school completion. Educational persisters included those individuals who (a) had successfully completed or were enrolled in a two-year postsecondary education institution (e.g., technical education, community college) or (b) were enrolled in a four-year postsecondary education program at the time of data collection. Educational persisters were compared to a second group who (a) had never enrolled in postsecondary education or (b) had enrolled in a two- or four-year program but left before completion. Two research questions guided the analysis: (a) Do differences exist in short-term postsecondary educational outcomes between students with learning disabilities or behavior disorders, and individuals without disabilities? (b) What risk-resilience factors influenced short- PERSISTENCE IN POSTSECONDARY EDUCATION 8 term postsecondary educational outcomes for groups with or without disabilities? Method Educational Longitudinal Study of 2002 (ELS:2002) Data from the Education Longitudinal Study of 2002 (ELS:2002), administered by the National Center for Education Statistics, was selected because of its focus on the transition of adolescents from high school to postsecondary education and work. The ELS:2002 contains a base-year sample comprised of 15,362 10th-graders drawn from 752 public and private school during the 2001-2002 school year. Subsequent administrations were conducted in 2004 and 2006. Our analysis included data from the first and second follow-up surveys as we focused on the transition period from 12th grade through two years after high school (Ingels et al., 2007). The initial sample was 10,760 and included 9,990 adolescents without disabilities (92.84%) and 770 adolescents with either specific learning disabilities or emotional-behavior disorders (7.16%). Identification of Students with Disabilities We used two methods to identify individuals with specific learning disabilities or emotionalbehavior disorders. The first method examined students’ base year status (grade 10) on two variables, provision of Special Education services through an Individualized Education Program (IEP) and indication of diagnosed disability using school transcript data. Drawing on previous studies (Hodapp & Krasner, 1994-1995; Reschly & Christenson, 2006), we also used a base-year question that asked parents about the presence and type of disability for their child. Transcript data identified students who received school credit in one or more of three types of special education-related coursework, including general special education (F1R54_C), special education-vocational (F1R55_C), and special education-resource curriculum (F1R56_C). We excluded students with other types of disabilities and those with multiple disabilities from our PERSISTENCE IN POSTSECONDARY EDUCATION 9 analysis. This approach was used in prior studies of NELS:88 data (Hodapp & Krasner, 19941995; Ingels & Scott, 1993). The final sample included all individuals without disabilities who participated in all three data collection points (n=9,990) and individuals who met established disability criteria in the base year and participated in all three data collection points, including 670 (6.23%) participants who reported a learning disability and received one or more disability-related services, and 100 (0.93%) reporting an emotional-behavioral disorder and receiving at least one disability-related service. The nondisabled group did not include other types of students with disabilities. Our sample compared favorably to percentages of students with specific learning disabilities and emotional-behavior disorder who received federally supported programs in 2002 and 2003 (5.9% and 1.0%, respectively; Snyder & Dillow, 2012). Over one-half of non-disabled adolescents were women (52.4%), while only 37.2% of the disability group was women (see Table 1). [Insert Table 1 about here] Measures Persistence in postsecondary education was constructed from second follow-up data using both postsecondary enrollment and completion status. Public high school graduates in 2004 who either enrolled in a postsecondary institution or completed a degree (or certificate) by 2006 were classified as persistent in postsecondary education, whereas those who had never enrolled or had enrolled and dropped out of postsecondary education were classified as not persistent. Individual risk-resilience factors included gender, occupational aspirations in grade 12, educational expectations in grade 12, and academic achievement scores including high school grade point average (GPA; M=2.667), reading achievement (M=50.661), and math achievement (M=49.723). Gender was coded “0” for adolescent men and “1” for adolescent women. PERSISTENCE IN POSTSECONDARY EDUCATION 10 Educational expectations were assigned the following values: less than college graduate=0, more than college graduate=1, uncertain/don’t know=2. Occupational aspirations were grouped according to level of job status: high prestige=0, medium prestige=1, and low prestige=2, and uncertain/don’t know=3. High school GPA was used to reflect participants’ general academic achievement (Bozick et al., 2006). Family risk-resilience factors were represented by SES, family composition (0=others, 1=two parents), parental communication about college attendance, and parents’ educational expectations. A standardized SES composite indicator (M= .00) was constructed by ELS:2002 researchers using five variables, including father’s and mother’s education, father’s and mother’s occupations, and family income (Bozick et al., 2006). Parental communication was measured with items asking how often respondents discussed going to college with their parents (never=0, sometimes=1, often=2). Parental educational expectation for their children was conceptualized as a dichotomous variable, either less than a 4-year college degree or 4-year college degree or more. School and peer risk-resilience factors were represented by the number of friends who had dropped out of high school and the number of friends planning to attend a four-year college. Both variables consist of four options including none=0, a few=1, some=2, and most/all=3. Community risk-resilience factor was measured using one item that asked respondents how often they performed community service. The variable consisted of four options; none=0, less than once a week=1, once a twice a week=2, and (almost) every day=3. Control variables were used to describe the sample and included English as native language and race/ethnicity. English as a native language was coded 0 for other than use of English and 1 for use of English. Race/ethnicity was coded 0 for White; 1 for Asian; 2 for Black; 3 for Hispanic, no race specified; 4 for Hispanic, race specified; 5 for more than one race; and 6 for PERSISTENCE IN POSTSECONDARY EDUCATION 11 Native American. Additional information on variables is found in Appendix. Data Analyses To investigate any existing differences in college persistence among students with learning disabilities, emotional-behavior disorders, and students without disabilities, we used a logistic regression model using a forced entry approach, which is generally employed for modeling the probability of an occurrence of an event through the use of associated covariates. The model can be written as logit Pr(π¦ππ = 1| π ππ ) = π½0 + π ′ππ π½, i = 1,…,C; j = 1,…,ni π logit π = log 1−π (1) (2) where π¦ππ denotes the outcome variable (1=persistent, 0=nonpersistent), C is the number of clusters (schools), ni is the number of individuals in cluster (school) i, π ππ denotes the vector of covariates, and π½ stands for the effects of covariates. The covariate vector π ππ was composed of variables measured to represent risk-resilience factors and several control variables. To adjust for school effects we incorporated the cluster (school) effect as a random effect in the logistic model, and a pseudo maximum likelihood estimation approach was adopted to estimate model parameters. We generated 20 multiply imputed data sets using a multiple imputation by the chained equations approach to handle missing values. Results Descriptive Results Table 1 summarizes descriptive statistics from the multiply imputed data sets used for analysis. Only 6.7% of the sample was composed of individuals with disabilities (87.5% specific learning disabilities, 12.5% emotional-behavior disorders). Approximately two-thirds of adolescents with disabilities were not persistent in postsecondary education, almost twice the rate PERSISTENCE IN POSTSECONDARY EDUCATION 12 of the nondisabled group. There were no observable differences between adolescents in the learning disabilities or emotional-behavior disorders groups. The proportion of adolescents with disabilities expressing uncertain occupational aspirations was 19.0%, while the rate for adolescents without disabilities was 42.1%. In terms of educational expectations, the proportion of adolescents expecting less than a 4-year college degree was almost double for adolescents with disabilities (48.9%) compared to the nondisabled group (23.5%). Corresponding proportions of adolescents with educational expectations for more than a 4-year college degree were much lower among the group with disabilities (35.0%) than the group without disabilities (69.1%). The GPA of adolescents with disabilities (M=2.167) was lower than adolescents without disabilities (M=2.703). The reading achievement scores of adolescents with disabilities (M=40.841) were lower than adolescents without disabilities (M=50.661). Math achievement scores of adolescents with disabilities (M=38.44) were also lower than those without disabilities (M=49.723). The SES of the nondisabled group was near zero (M=0.002), reflecting the standardized mean. The group with disabilities showed a significantly negative SES (M=-0.205), indicating that adolescents with disabilities were from lower SES families. Adolescents with disabilities indicated that their friends were less likely to go to a 4-year college than students without disabilities. Although 51.9% of individuals without disabilities indicated that friends planned to go to college, only 28.7% of individuals with disabilities did so. A large difference existed in the outcome, persistence in college, between adolescents with disabilities (32.4%) and nondisabled peers (63.0%). Comparison by Disability Type The base model revealed that after holding native language and race/ethnicity constant, the PERSISTENCE IN POSTSECONDARY EDUCATION 13 persistence of adolescents without disabilities was significantly different from those with disabilities. The estimated odds ratio for individuals with emotional-behavior disorders and college persistence was 0.305 (coefficient = -1.185, 95% confidence intervals [CI] for odds ratio [OR] = 0.156-0.598), whereas the odds ratio estimate for persons with learning disabilities and college persistence was 0.295 (coefficient = -1.221, 95% CI for OR = 0.239-0.363). Adolescents with emotional-behavior disorders were approximately 70% [=(1-0.305)×100] less likely to enroll or persist in college than adolescents without disabilities. Adolescents with learning disabilities were approximately 71% [=(1-0.295)×100] less likely to enroll or persist in college than nondisabled peers. Design-adjusted Wald tests determined that disability status was a significant predictor of college persistence [F(2, 379) =71.68, p <.001]. Risk-Resilience Factors for Persistence in Postsecondary Education Risk-resilience factors were included in the base model to determine their influence on college persistence (see Table 2). The Hosmer-Lemeshow Goodness-of-Fit test suggested no evidence of lack of fit (πΆΜ =10.87, df=8, p=.21). Estimated coefficients of disability type revealed that while individuals with emotional-behavior disorders were not statistically different from peers without disabilities in persistence after holding risks-resilience factors constant, individuals with learning disabilities experienced a significant deficiency in the odds of persisting when compared to persons without disabilities (coefficient=-0.300, OR=0.741, 95% CI for OR=0.5740.956). The odds of not persisting were 25.9% higher for adolescents with learning disabilities than for peers without disabilities when controlling for other covariates. Educational expectations, high school GPA, and math achievement showed positive effects on persistence. Individuals who expected to attain more than a college degree had almost two times greater odds (coefficient =0.708, OR =2.029, 95% CI for OR=1.735-2.373) of persisting in college than those expecting PERSISTENCE IN POSTSECONDARY EDUCATION 14 less than a college degree. The odds ratio for high school GPA was 2.346 (95% CI for OR=2.107-2.613), meaning that adolescents with higher high school GPAs were more likely to persist in postsecondary education. Adolescents with higher math achievement scores were also more likely to persist in postsecondary education (coefficient=.024, OR=1.024, 95% CI for OR=1.014-1.036). Unlike individual factors, all, as opposed to some, family factors proved to be important for college persistence. SES was significantly favorable to persistence (coefficient=0.514, OR=1.672, 95% CI for OR=1.515-1.845), individuals with higher family SES were more likely to persist in college than their peers with low SES (see “All Participants v Disabilities model” in Table 2). The group of adolescents indicating two-parent family composition had an odds ratio of 1.166 (coefficient=0.154, 95% CI for OR=1.033-1.317), indicating that adolescents who live with both parents were 17% more likely to persist in postsecondary education than their peers who lived with a single parent. Compared with those who had never discussed college with a parent, those who had discussed college with a parent were more likely to be involved and persist in college (sometimes: coefficient=0.330, OR=1.391, 95% CI=1.018=1.901; often: coefficient =0.757, odds ratio =2.132, 95% CI=1.594-2.853). In other words, the more often parents and children discussed college, the more likely children were to be enrolled and persistent in postsecondary education. Similarly, parents’ educational expectations were also important. Compared to the less-than-college group, the higher expectation group was 25% more likely to persist in postsecondary education (coefficient=0.223, 95% CI for OR=1.040-1.503). [Insert Table 2 about here] School-peer and community factors had significant impact on college persistence, specifically pertaining to adolescents who had observed friends dropping out of school. PERSISTENCE IN POSTSECONDARY EDUCATION 15 Compared to those who did not have any friends dropping out of school, individuals with some friends dropping out of school (coefficient = -0.410, OR=0.664, CI for OR=0.542-0,813) were less likely to be persistent in postsecondary education. Although degraded persistence levels of the few and most/all friends had dropped out groups seem insignificant, the negative effects of experiencing friends leaving high school cannot be disregarded. More important, the designadjusted Wald test demonstrated that the parameters associated with the student drop out factor were significantly different from zero, suggesting that the peer factor was an important predictor of college persistence. Friends’ plans for attending a four-year college also proved to be important. All estimates were positive at all levels with the none group as a reference group, which suggests that friends’ plans for college were likely to be corollary to persistence. In particular, the most/all friends going to college group was more likely to persist in postsecondary education than the none of friends going to college group (coefficient=0.413,OR=1.511, 95% CI for OR=1.154-1.980). Moreover, significant results of the design-adjusted Wald test suggest that the peer factor was an important predictor. Students who participated in community service less than once a week during high school were more likely to persist in postsecondary education than peers who did not serve. The design-adjusted Wald test indicated that the parameters associated with community service were significantly different from zero. Influential Risk-Resilience Factors for Persistence of Individuals with Disabilities Since no statistically significant differences in persistence existed between disability types, this factor was disregarded while fitting the logistic regression model. Table 2 (disabilities model) depicts the logistic regression model applied only to individuals with disabilities (πΆΜ =8.92, df=8, p=.34). High school GPA (OR=1.772, 95% CI for OR=1.241-2.529), and SES (OR=2.465, 95% CI for OR=1.685-3.605) were of particular importance for understanding the persistence PERSISTENCE IN POSTSECONDARY EDUCATION 16 dynamic. Adolescents with higher GPAs and higher SES families were more likely to persist in college than peers with lower GPAs and lower SES families. Friends’ plans for college also favorably affected persistence (coefficient =0.837, OR=2.309, 95% CI=1.104-4.831). The few friends going to college group was more likely to persist than the none of friends going to college group. However, the design-adjusted Wald test suggested that a friend’s plans for college might not be a significant predictor of college persistence when controlling for the associations between other variables with college persistence. Discussion This study investigated the usefulness of selected factors in explaining educational outcomes for young adults with and without disabilities. When the model containing all participants regardless of disability status was examined, all risk-resilience covariates, except for occupational aspirations and reading achievement, were significantly associated with the likelihood of persisting in postsecondary education. However, only a few variables—high school GPA, SES, and peers’ plans to attend a 4-year college—were significantly associated with the model of college persistence when only examining students with disabilities. This result indicated an important and noteworthy difference for adolescents with disabilities. It is possible that these three salient factors contribute more meaningfully to the college persistence of students with disabilities compared with students without disabilities. In this section, we discuss how these risk-resilience factors contribute to an understanding of postsecondary education persistence of adolescents with specific learning disabilities or emotional-behavior disorders, and we provide limitations of the study and implications for practice and future research. Impact of Risk-Resilience Factors on Educational Persistence Influence of disability status. Results of our base model (control variables only) supported PERSISTENCE IN POSTSECONDARY EDUCATION 17 previous research findings on the association between disability status and college persistence (e.g., DaDeppo, 2009; Murray et al., 2000; Wagner et al., 2005). The adolescents with disabilities in our analysis persisted in postsecondary education at lower rates than students without disabilities. Disability status is an important, albeit indirect, risk factor in explaining college persistence. The presence of a disability may pose barriers because of self-perceptions. Students might experience failure in academics based on their disability status, perceived disability-related failure, or overly positive self-perception; the disability label itself, implying a difficulty in learning or actual difficulty with learning, contributes to a lowered chance of enrolling in or completing postsecondary programs or of not receiving the academic or emotional support necessary to be successful in a competitive academic environment (Cosden & McNamara, 1997; Heath, Roberts, & Toste, 2011; May & Stone, 2010). Influence of high school GPA. Among individual risk-resilience factors, students with higher GPAs were more likely to persist in postsecondary education. Although the importance of academic achievement for success in postsecondary education for students with disabilities has been downplayed (e.g., DaDeppo, 2009), our results reflect its importance, and these outcomes coincide with studies that have demonstrated the consistent (and primary) role of academic achievement in postsecondary education (e.g., Bozick et al., 2006; Mamiseishvili & Koch, 2011). The importance of the high school GPA on college persistence can be further supported by the Social Cognitive Career Theory persistence model, highlighting a significant indirect effect of high school GPAs on college persistence via academic self-efficacy and goals (Brown et al., 2008). Role of occupational aspirations. The uncertainty in occupational aspirations expressed by adolescents with disabilities was considerably less than the uncertainty of adolescents without PERSISTENCE IN POSTSECONDARY EDUCATION 18 disabilities. Despite this difference, occupational aspirations did not help explain college persistence, suggesting that persistence is more sensitive to shorter-term anticipation or experience than by perceived longer-term benefits or goals. In contrast, research on short-term work outcomes and work-bound adolescents with disabilities revealed that occupational aspirations significantly predicted the number of hours worked per week for work-bound adolescents with specific learning disabilities or emotional-behavior disorders (Rojewski, Lee, & Gregg, in press). It is likely that educational expectations and attainment may play significant roles as mediators of occupational aspirations (i.e., indirect influence of occupational aspirations on college persistence through educational expectations) in understanding our results because persistence and attainment in postsecondary education are considered to be more important short-term goals for college-bound adolescents with disabilities, compared to work-bound adolescents with disabilities. Influence of SES. One of the most consistent findings on college persistence is the pervasive influence of SES. A recent study by Chen and St. John (2011) found that individuals from high SES families have 55% higher odds of persisting in college than adolescents from low SES families. Similar to past studies, in our analysis, SES played an important role in the persistence of students with disabilities. It is important to note that although all family risk-resilience factors were significantly associated with the college persistence of nondisabled adolescents, only SES was significantly associated with persistence for adolescents with disabilities. This finding suggests that SES-related differences in parenting or opportunities to access academic resources may contribute to college persistence. Peer influence on college persistence. The literature provides limited information about the influence of high school friends or peers on postsecondary education outcomes. However, the PERSISTENCE IN POSTSECONDARY EDUCATION 19 importance of social networking and support influences social resources available to individuals in learning situations (Scott, 2000). In our study, only one social factor, friends’ plans to attend college, had a significant association with college persistence for adolescents with disabilities. Although the model containing all participants showed that students with most or all of their friends planning to attend a four-year college were more likely to persist in postsecondary education than were students with few friends planning to attend, results of the logistic model for disabilities showed that even a few friends planning to attend college contributed to a greater persistence for adolescents with disabilities. These findings suggest that students with specific learning disabilities or emotional-behavior disorders are more likely to be influenced by a few close friends, who may provide them with the academic or emotional support necessary for college persistence, than those without disabilities. However, caution is warranted in interpreting this finding because of a statistically insignificant result of the design-adjusted Wald test. Limitations of the Study This study contains several limitations. Although the ELS:2002 database provided an excellent opportunity to examine our research questions, it is not specifically designed to examine disability issues. Fortunately, unlike previous national longitudinal databases, e.g., NELS:88, in which some students with disabilities were excluded from the base year sampling, this was not the case with the ELS:2002 sampling scheme (Ingels et al., 2007). Even so, reliance on a school-based diagnosis to identify students with disabilities likely resulted in our sample being less homogeneous than might have been expected. Therefore, we exercised caution in identifying individuals with disabilities, and relied on several different criteria depending on availability. Our study was delimited by the time between high school completion and two years after PERSISTENCE IN POSTSECONDARY EDUCATION 20 high school graduation. Since students with disabilities are both less likely to go on to postsecondary education and, when they do, are more likely to make a delayed entry into higher education, the two-year window for studying persistence in postsecondary education provides a limited, albeit important, picture of persistence behaviors in postsecondary education. This delimitation can be addressed in the near future with the scheduled release of the ELS:2002 third follow-up data in 2014. This data will provide information on outcomes eight years after high school. Although a full understanding of the transition process requires longer periods of assessment, it is important to acknowledge and understand this shorter period of time, especially as many adolescents, regardless of disability status, experience prolonged periods of floundering in the first few years after high school (Blackorby & Wagner, 1996). Because our results apply only to individuals with disabilities graduating on time with same-age peers, our results could be strengthened by future studies that analyze students who fall behind the modal sequence in high school. Implications for Practice and Future Research It is important for parents, school teachers, and counselors to continuously interact and engage with adolescents with specific learning disabilities or emotional-behavior disorders by recognizing that these factors are important indicators of short-term postsecondary education outcomes. In particular, existing school programs may strengthen the relationship with parents to encourage their involvement at home in helping, motivating, and encouraging students to succeed academically (e.g., McDonnall, Cavenaugh, & Giesen, 2012) and to provide relevant resources and information for students, especially from low SES families, to moderate the influence of SES. Moreover, school teachers can develop peer mentoring programs to support peer interactions that may influence students’ study strategies or short-term postsecondary plans PERSISTENCE IN POSTSECONDARY EDUCATION 21 and outcomes. Future study is needed to examine how policy-related strategies or interventions (e.g., federal Pell Grants) may reduce the effect of SES on educational persistence for adolescents with disabilities and how school-parent partnerships and peer mentoring programs can increase students’ academic achievement and postsecondary outcomes. Future research may take several directions. First, it may prove worthwhile to examine the combined influence of the 16 in-school predictors identified by Test et al. (2009), along with the risk-resilience factors we examined in this study on college persistence of other disability types using the either the National Longitudinal Transition Study-2 (NLTS-2) or ELS:2002 database. A second avenue for research may be to incorporate aspects of Tinto's (1987, 1992) theory of students’ departure/persistence, developed for students without disabilities, to students with specific learning disabilities or emotional-behavior disorders. To date, a specific application of this theory to adolescents with disabilities is lacking. It is possible that all or part of Tinto’s work may transfer to adolescents with disabilities and help to explain why students with disabilities do or do not persist in postsecondary education environments. Third, the mediation effect of interactions between individuals’ attitudes and institutional experience, along with indirect influences of risk-resilience factors on college persistence via academic self-efficacy and goals for youths with disabilities, is worth pursuing. Finally, we should not disregard the contribution of non-significant risk-resilience factors on college persistence. Indeed, risk-resilience variable coefficients in the disabled group model were higher than those for the nondisabled group model. We speculate that a relatively high number of variations might explain the lack of significance for most factors in the disabled group model. Future studies using relatively homogenous data such as NLTS-2 are necessary to determine whether other risk-resilience factors may contribute to college persistence.
