Relationship between Experiential Avoidance and Emotional Disturbances in Coping with Disease in Patients with Multiple Sclerosis

Multiple sclerosis (MS) is a neurodegenerative disease that presents with both motor and non-motor symptoms, with anxiety and depression being prominent and potentially exacerbated by negative thoughts. Therefore, the experiential avoidance (EA) exhibited by patients post diagnosis is particularly relevant. This study aimed to measure the degree of EA in patients with MS and determine its relationship with emotional disturbances. A cross-sectional descriptive study was conducted using a sample of 64 patients diagnosed with MS. In October 2018, these patients underwent evaluations of functional and cognitive variables, such as anxiety, depression, and avoidant behaviors towards the disease, using the Expanded Disability Status Scale, Acceptance and Action Questionnaire-II, Self-Compassion Scale Short Form, Five Facet Mindfulness Questionnaire-15, prefrontal symptoms inventory, Beck Depression Inventory II, and State-Trait Anxiety Inventory to assess coping mechanisms in handling the disease. Higher levels of state anxiety (β = 0.79; <i>p</i> < 0.001), trait anxiety (β = 0.82; <i>p</i> < 0.001), and depression (β = 0.62; <i>p</i> < 0.001) were observed in patients with MS as their EA and psychological inflexibility increased. Participants with high self-compassion/self-acceptance tended to have fewer negative thoughts and exhibited better coping with the disease, which may, in turn, affect patterns of psychological rigidity or inflexibility. Dimensions such as kindness and humility could act as positive factors in coping with the disease, whereas self-judgment and isolation are negative elements often associated with avoidant behaviors that hinder effective coping with the illness.
