OBJECTIVE: Fibromyalgia syndrome (FMS) is a condition of chronic widespread pain. In its process of chronification psychosocial factors play an important role. A multimodal treatment including integrated group therapy has been proved to be effective. Yet little attention has been paid so far to the exact sequence of changes and interrelation between psychosocial factors, functional capacity, and level of pain under integrated group therapy for FMS patients. METHODS: One FMS patient was exemplarily monitored with an electronic diary over 13 weeks while undergoing integrated group therapy. On a daily basis we assessed the level of pain, functional capacity, and other disease-related variables (anxiety, depression, quality of sleep, self-efficacy) via visual analog scales. By the means of multivariate time series analysis the timing of changes in psychosocial factors and their effects on perceived functional capacity was identified. RESULTS: Under integrated group therapy all assessed variables gradually changed in the predicted way. Pain, depression, anxiety could be reduced, whereas self-efficacy, quality of sleep, and functional capacity improved. 71% of the variance could be explained by the multiple regression model. Self-efficacy was, beside pain intensity and depression, an important predictor for functional capacity on the same day. High self-efficacy correlated negatively with the level of functional capacity 3 days later. CONCLUSION: Integrated group therapy proved to be effective. Self-efficacy played an important role regarding the improvement of functional capacity. Depicting the exact timing of changes in the assessed variables helped to detect patterns of influence and indicate directions for further treatment.
