Abstract
Abstract Objective This study evaluated the relationship between subjective cognitive complaints, objective cognitive performance, and psychological outcomes among clinical patients referred for persisting cognitive concerns following SARS-CoV-2 infection. Method The sample consisted of 49 patients (69.4% female; 38.8% Black, 36.7% White, 18.4% Hispanic, 6.0% Other; Mage = 45.27, SD = 12.08; Meducation = 15.49; SD = 3.0) referred for neuropsychological evaluation to assess for long-term post-SARS-CoV-2 cognitive changes. All patients were administered a uniform neuropsychological test battery that included measures of working memory, processing speed, and verbal learning/memory, as well as measures of anxiety, depression, and perceived stress. Degree of subjective cognitive concerns was established using the Neurobehavioral Symptom Inventory (NSI) cognitive subscale. Linear regression models were conducted between the NSI cognitive subscale and each cognitive and psychological outcome. Results NSI cognitive scale predicted all psychological (depression [F = 31.37, p < 0.001(R2 = 0.41)]; anxiety [F = 6.71, p = 0.01(R2 = 0.13); perceived stress [F = 4.40, p = 0.04(R2 = 0.10)]) variables. The NSI cognitive scale also significantly predicted working memory [F = 4.624, p = 0.04(R2 = 0.09)]; however, no individual scores fell below the low average range upon further analysis. Cognitive complaints did not significantly predict any other cognitive (processing speed [F = 0.002, p = 0.97(R2 = 0.00)], total learning [F = 0.14, p = 0.71(R2 = 0.00)], and delayed recall [F = 1.03, p = 0.32(R2 = 0.02)]) variable. Conclusions Subjective cognitive complaints significantly predicted self-reported psychological symptoms including depression, anxiety, and perceived stress, while working memory was the only cognitive performance with a similarly meaningful relationship. These preliminary findings suggest that the psychological effects of persistent symptoms following SARS-CoV-2 infection, rather than objective cognitive changes, may better explain subjective cognitive concerns reported by this population.
