What this trial studies

This study evaluates the effectiveness of Acceptance Commitment Therapy (ACT) and micro breaks in managing symptoms of Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME). Participants diagnosed with CFS/ME will engage in either ACT or micro breaks to assess improvements in their fatigue and overall functioning. The study aims to determine which intervention is more beneficial for enhancing the quality of life in affected individuals. The approach includes online therapeutic procedures, making it accessible for participants with internet access.

Why it matters

Potential benefit: If successful, this study could provide effective non-pharmacological treatment options for patients suffering from chronic fatigue syndrome.

How similar studies have gone: Other studies have shown promise in using psychological therapies for chronic fatigue, but this specific comparison of ACT and micro breaks is novel.
