Importance of coping in the relationship between executive function and quality of life in people with multiple sclerosis

Abstract

Background: Maximizing quality of life (QOL) for people with multiple sclerosis (MS) is a primary focus of health care management professionals. Research has shown a relationship between QOL and a person's coping style and that coping provides an indirect link between cognition and stress, depression, and anxiety in MS. This research assessed whether coping moderates or mediates the relationship between executive function and QOL in people with MS. Methods: We assessed 107 people with relapsing-remitting (n = 83) or secondary progressive (n = 24) MS using executive function tasks and self-report coping and QOL inventories. Results: Coping strategies that mediated the relationship between executive function and QOL in people with MS included behavioral disengagement, acceptance, growth, and religion, while moderating strategies were denial, active, religion, adaptive, and total coping indices. Less cognitively demanding coping strategies that were related to increased QOL in people with poorer executive function included acceptance, growth, and religion, and maladaptive strategies associated with poorer QOL were behavioral disengagement and denial. Conclusions: These results suggest that lessening avoidant coping strategies and strengthening use of less cognitively demanding adaptive coping strategies may improve QOL in people with MS who experience deficits in executive function. Consideration should be given to the development of psychoeducation and interventions with this focus.
