A Study of Digital Cognitive Behavioural Therapy for Insomnia in Fibromyalgia

The goal of this clinical trial is to investigate the potential benefits of a digital Cognitive Behavioural Therapy for Insomnia (dCBT-I) platform, Sleepio, in individuals suffering from fibromyalgia, a condition commonly associated with cognitive issues and sleep disorders. The main questions this study aims to answer are: * Does the application of Sleepio improve quality of life in individuals with fibromyalgia? * Does the use of Sleepio improve cognitive function in individuals with fibromyalgia? * Does the use of Sleepio enhance sleep quality in these same individuals? * Does the use of Sleepio improve motor function in this group? Participants will be randomly assigned to either use the Sleepio platform or standardised health advice, including sleep hygiene material. Those assigned to Sleepio will undergo a series of six 20-minute sessions over 10 weeks with a virtual therapist focusing on cognitive and behavioural strategies for improving sleep. Participants' quality of life, cognitive function, sleep quality, and pain levels will be monitored and evaluated using online assessment tools. Additionally, a subset of participants will undergo further testing via sleep actigraphy and/or neuroimaging with MRI scans. Researchers will compare the two groups to determine if the use of Sleepio has a positive effect on quality of life, cognitive function, and sleep quality.
