OBJECTIVES: To determine whether self-efficacy longitudinally predicts 2 types of
perceived cognitive impairment (PCI) in multiple sclerosis (MS): general
cognitive functioning and executive functioning; and secondarily to assess
whether self-efficacy mediates the relationships between depression, fatigue, and PCI. DESIGN: Longitudinal analysis of self-report survey data collected over 3
years. Hierarchical regression analyses examined the relationship between
self-efficacy and PCI, adjusting for depression and fatigue. Additional analyses
tested self-efficacy as a mediator between depression, fatigue, and PCI. SETTING:
Community. PARTICIPANTS: Community-dwelling individuals with MS (N=233; age
range, 22-83y) were recruited from a larger longitudinal survey study of
individuals with MS (N=562). INTERVENTIONS: Not applicable. MAIN OUTCOME
MEASURES: Primary outcome measures were the Applied Cognition-General Concerns
and the Applied Cognition-Executive Function domains of the Quality of Life in
Neurological Disorders (NeuroQoL) measures. RESULTS: Self-efficacy was
significantly correlated with PCI at baseline (r=.40-.53) and 3 years later
(r=.36-.44). In multivariate regression analyses, self-efficacy was a significant
longitudinal predictor of PCI, both for general cognitive functioning (beta=.20,
P<.01) and executive functioning (beta=.16, P<.05). Self-efficacy partially
mediated the relationships between depression, fatigue, and PCI. CONCLUSIONS:
Self-efficacy may influence how individuals with MS perceive their cognitive
functioning over time. Interventions that target self-efficacy, particularly
early in the disease course, may lead to improvements in PCI, as well as
improvements in fatigue and depression.
