Evaluation of change in fatigue, self-efficacy and health-related quality of life, after a group educational intervention programme for persons with neuromuscular diseases or multiple sclerosis: a pilot study.

Purpose: An intervention for persons with neuromuscular diseases (NMD) or multiple sclerosis (MS) who experienced severe fatigue was developed which aimed at educating participants in maintaining a balance between capacity and load in their daily activities. This pilot study evaluated the results of this intervention.
Methods: Persons with NMD or MS who experienced severe fatigue were included. Outcome measures were: fatigue (Fatigue Severity Scale), health-related quality of life (HRQoL; SF-36) and self-efficacy (ALCOS-16). Changes in scores between the start of the intervention (T0) and 3 months post-intervention (T1) were tested with the Wilcoxon tests in the complete group and in subgroups (gender, education, high/low self-efficacy).
Results: Forty-three persons participated. Significant improvements of HRQoL were found for the domains role-physical, mental health and general health perceptions. Subgroup analyses showed more improvement in males (fatigue, role-physical, vitality, bodily pain, general health perceptions), participants with lower education (role-physical, vitality) and participants with low self-efficacy at T0 (self-efficacy, mental health, general health perceptions) than in females, participants with higher education and participants with higher initial self-efficacy.
Conclusion: This pilot-study provides preliminary evidence for the effectiveness of a group educational intervention in improving HRQoL without increasing fatigue in persons with NMD and MS.
