Are Mental Health and Neurodevelopmental Conditions Barriers to Postsecondary Access? Analytical Studies Branch Research Paper Series

The Canadian literature on postsecondary access has identified many of its key determinants including parental education and income, academic performance, and sex. However, relatively little work has investigated the independent role of disability in postsecondary enrollment. This study fills that gap by estimating the relationship between mental health and neurodevelopmental conditions diagnosed in childhood (available from the National Longitudinal Survey of Children and Youth [NLSCY]) and postsecondary enrollment during early adulthood (available from the tax credits on the T1 Family File [T1FF]). The study is possible as a result of the recent linkage between the NLSCY and T1FF. The findings suggest that 77% of youth who were not diagnosed with any long-term health condition in their school years (the comparison group) enrolled in postsecondary education (PSE) by their early 20s. In contrast, 60% of youth diagnosed with a neurodevelopmental condition (NDC) enrolled in PSE in the same time frame (a gap of 17 percentage points), while only 48% of youth diagnosed with a mental health condition (MHC) enrolled in PSE (a gap of 29 percentage points compared with youth in the comparison group). Youth diagnosed with both an NDC and an MHC were even less likely to enroll, with only 36% going on to PSE (41 percentage points behind youth in the comparison group). Differences in sex, academic performance and family background (e.g., parental income and education) explain only about one-third of these gaps. Among the MHCs, the most common diagnosis was Attention Deficit Hyperactivity Disorder (ADHD). Youth with an ADHD diagnosis were less likely to pursue PSE than youth diagnosed with other types of MHCs such as emotional, psychological or nervous difficulties. These findings suggest that youth diagnosed with NDCs and MHCs in their school years face barriers to enrolling in PSE that are distinct from those confronting other youth.
