We found no indication that IPST for MS patients with moderate or severe depression is effective in reducing depressive symptoms compared to a waiting list. Large improvements in the wait list control were unexpected and are discussed.
This study suggests that applied web-based PST is feasible and reduces depressive symptoms in MS patients. Especially MS patients who experience disease-related or other barriers to participate in face-to-face counselling could benefit. However, ways to increase compliance should be considered. A randomized controlled trial is recommended to more extensively investigate effectiveness of this intervention in treating depressive symptoms in MS patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
