The impact of depression and anxiety on speed of academic performance and retrieval fluency in postsecondary students.

Abstract

Objective: This study evaluated the functional effects of severe mental health symptoms on speed of academic performance to assist clinicians and educators in determining whether extra time accommodations are evidence-based for students with such diagnoses. Method: Using archival data from 1476 post-secondary students, we examined the performance of students with existing mental health diagnoses who were also reporting extremely high levels of symptoms. Their performance on timed academic achievement and cognitive processing measures was compared with performance of students with learning disabilities, Attention Deficit Hyperactivity Disorder, and clinical controls. Students failing stand-alone performance validity and/or symptom validity measures were excluded from this investigation. Results: Students diagnosed with anxiety and/or depression did not differ from clinical controls on any timed performance measure, typically performing academic tasks within a normal amount of time. By contrast, those with reading disabilities were typically the slowest on all academic tasks. Conclusion: Across the range of timed tests, students with mental health diagnoses did not show functional impairments in tests with a speed component. As such, they would not typically require increased time to perform speeded academic tasks, but they might require alternative accommodations in their post-secondary programmes in order to participate equally.
