Outpatients of two neurology services who had functional symptoms rated by a neurologist as "not at all" or only "somewhat" explained by organic disease were randomly allocated to two groups. One group received “usual care,” the other also received guided self-help in the form of a self-help manual and four 30-minute guidance sessions. The primary outcome was self-rated health on a 5-point Clinical Global Improvement scale (CGI) at three months. The researchers found that CBT-based, guided self-help therapy improved self-reported general health, as measured by the CGI, in patients with functional neurologic symptoms.
