Feasibility trial of a telehealth support group intervention to reduce anxiety in multiple sclerosis.

OBJECTIVE

Anxiety is common among persons with MS (PwMS), but widely accepted treatments are lacking. Group-based interventions delivered via telehealth are an accessible treatment option requiring clinical trial evidence to support feasibility and initial efficacy. We conducted a pilot feasibility trial of an online support group intervention to reduce anxiety in PwMS.

METHODS

A non-randomized, parallel arm clinical trial was conducted. A total of 31 PwMS were enrolled: 20 completed a 12-week telehealth-delivered support group intervention and 11 were assigned to a survey-only control group. Primary feasibility outcomes were adherence and completion rates. Primary efficacy outcome was anxiety, secondary outcomes were depression, loneliness, distress, self-efficacy, stress, and quality of life.

RESULTS

Twenty-six participants completed the study. Intervention group adherence (75%) and completion (85%) rates were acceptable. Results indicated a medium size between-group effect, suggesting a greater reduction in anxiety in the intervention group compared to the control group [ = 39.50,  = 0.045,  = 0.39]. No group differences in other outcomes were observed.

CONCLUSION

A telehealth-delivered support group intervention appears feasible for further study and shows initial efficacy for the reduction of anxiety in PwMS.
