Effectiveness of psychologically focused group interventions for multiple sclerosis: A review of the experimental literature.

Psychologically focused group interventions for multiple sclerosis were reviewed. Studies reviewed (14) were quantitative, experimental and involved a comparison group (control or other intervention). Compared with controls, psychologically focused group interventions achieved considerable improvements in depression and moderate improvements in self-efficacy and quality of life but little change in anxiety. Psychologically focused group interventions compared well with other interventions, although evidence was limited. Psychologically focused group intervention was less effective short term for depression than individual cognitive behavioural therapy or medication but comparable long term. Intervention heterogeneity made comparisons difficult. Specificity of effect is unclear. Limited evidence suggests psychologically focused group intervention is effective in improving certain outcomes.
