The American Psychiatric Association (APA) is proud to join the more than 500 international organizations that are supporting AllTrials as sponsoring organizations. The APA supports public accessibility to the methods and findings related to clinical trials, which has direct implications on psychiatric treatments and quality of care. The APA believes a comprehensive registry of all clinical trials, whether publicly or privately funded, will be imperative in demonstrating transparency, reducing selective reporting of findings, and alleviating mistrust surrounding published data on the efficacy and safety of psychiatric medications for children and adults with mental disorders. The AllTrials campaign will support this effort while promoting knowledge sharing to the benefit of psychiatric patients and the mental health field as a whole.
