Efficacy of an emotion-focused treatment for prolonged fatigue.

Previous research findings have suggested a relationship between less adaptive emotional functioning and fatigue. The present study used a research design involving multiple baselines across participants to evaluate the efficacy of a new emotion-focused treatment for prolonged fatigue delivered in a cognitive behavioral therapy framework. The 13 adults participating in the study met the criteria for prolonged fatigue and provided fatigue baselines of 2, 5, or 8 weeks. The results indicated that the treatment was effective, with fatigue severity levels after the initiation of treatment significantly lower than that predicted by baseline patterns, as determined by the split median method of trend estimation. At 3-4 months after treatment, 8 of 11 clients who completed the treatment no longer met the criteria for prolonged fatigue.
