Clinical utility of brief screening measures during neuropsychological consultation for pediatric onset multiple sclerosis.

ABSTRACT

OBJECTIVE: Pediatric-onset multiple sclerosis (POMS) accounts for approximately 2 to 5% of all individuals with MS and is associated with an increased risk for cognitive impairment. In recent years, neuropsychological screening questionnaires have been increasingly utilized for pediatric populations in multidisciplinary settings. This study examines the clinical utility of the Colorado Learning Difficulties Questionnaire (CLDQ) and Pediatric Perceived Cognitive Functioning (Peds PCF) screening measures for identifying cognitive impairment in persons with POMS during a target neuropsychological evaluation. METHOD: Retrospective data was gathered from electronic medical records at a single pediatric hospital. RESULTS: Forty-nine participants were included (69% female; 43% Hispanic/Latinx; mean age = 16.1 years old, range = 9.9 to 20.6 years old). Correlation analyses demonstrated strong interrelatedness between caregiver ratings on screening measures and performance on traditional neuropsychological measures. Effect sizes were medium across comparisons (CLDQ Spearman's rho = -.321 to -.563; PedsPCF Spearman's rho = .308 to .444). Exploratory cut-points using receiver operating characteristic analysis and Youden indices are also discussed. CONCLUSIONS: Comparison of scores across caregiver rating questionnaires and on a targeted neuropsychological battery suggests that the screening surveys alone may not be sensitive enough to identify children with cognitive impairments, but ratings may provide qualitatively meaningful information along with neuropsychological testing. This study illustrates how pediatric neuropsychologists can leverage screening tools to focus consultative interviews and effectively triage referrals for evaluation within an academic medical setting.
