Stability of Depression in Patients with Multiple Sclerosis
Objectives: To evaluate the stability of depression in MS patients over a period greater than five years.
Methods: Participants (N= 349) were recruited from an outpatient clinic at a large medical center in New Jersey. Longitudinal data were collected as part of an ongoing research project. Participants completed a Beck Depression Inventory-II (BDI-II) and a demographic questionnaire. Linear regression was used to examine the relationship between time and change in BDI-II score. Linear regression was also used to relate BDI-II scores at baseline and follow-up.
Results: Initial BDI-II significantly predicted BDI at follow-up (β = .603, p < .001). Time did not predict a change in BDI-II score (β = - .026, p= .625).
Conclusions: Depression is highly stable in the MS population over more than a five-year span.
