Clinical Trial Summary

The purpose of this study is to assess the safety and efficacy of a newly developed psychotherapy for schizotypal personality disorder. This new form of psychotherapy integrates compassion focused therapy and metacognitively oriented psychotherapy.


Description:

After being informed about the study and potential risks, all patients giving written informed consent will undergo a psychological assessment so as to determine eligibility for study entry. Patients who meet the eligibility requirements will be randomized in a double-blind manner in a 1:1 ratio to new integrative psychotherapy or treatment as usual (cognitive behavioral therapy plus standard psychopharmacological treatment). One month after the conclusion of the two forms of treatment (both lasting 6 months), patients will have access to the final follow-up assessment.
