What this trial studies

This clinical trial evaluates the effectiveness of a novel internet-based therapist-assisted treatment program called 'One step at a time' for patients suffering from moderate to severe functional somatic disorders (FSD). The study involves 166 participants who will be randomly assigned to either the experimental treatment or an active control program called 'Get Started'. The primary outcomes will focus on self-reported physical health and treatment satisfaction over a 14-week period. The trial aims to determine if the therapist-guided approach leads to better health outcomes compared to a non-guided treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-60 with a diagnosis of moderate to severe functional somatic disorder lasting more than six months.

Not a fit: Patients with severe comorbid somatic or psychiatric diseases that are not adequately treated may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for patients suffering from severe functional somatic disorders.

How similar studies have performed: Other studies have shown promise with internet-based treatments for similar conditions, indicating potential for success in this approach.
