Objectives: To examine the association between subjective and objective prospective memory (PM) in people with multiple sclerosis (PwMS)., Design: Secondary analysis of a cross-sectional cohort study., Setting: Community-based comprehensive multiple sclerosis center., Participants: PwMS (N=112) who completed a battery that included measures of PM, depression, and fatigue., Interventions: Not applicable., Main Outcome Measures: Objective PM was measured with the performance-based Memory for Intentions Test (MIST), whereas subjective PM was assessed with the self-report Perceived Deficits Questionnaire-Prospective Memory (PDQ-PM)., Results: PwMS had low scores on the PDDS (median=2) and HADS-D (median=5.29), with 26.8% scoring 1 standard deviation or lower (≤15th percentile) on the MIST. Objective PM was significantly associated with subjective PM in a multivariate model (β=-0.18, P=.036), which accounted for demographics, physical disability, retrospective memory, and depressive and fatigue severity. Physical disability, depression, and fatigue were also significant contributors to subjective PM. Time-based PM performance emerged as the specific component that was associated with subjective PM., Conclusions: These findings suggest that among PwMS with relatively mild impairment and symptomatology, their objective PM performance was associated with their self-assessments, even when considering retrospective memory and factors that influence their cognitive perceptions. The results expand upon the subjective-objective cognition discrepancy literature in multiple sclerosis and highlights how the PDQ-PM could be used as a complementary measure to help identify difficulties with PM., (Copyright © 2024 American Congress of Rehabilitation Medicine.
