NIMH Twitter Chat on Suicide Prevention

Science Update

About one million people worldwide die annually by suicide—there is one death by suicide every 40 seconds. The number of lives lost each year through suicide exceeds the number of deaths due to homicide and war combined. Despite these daunting numbers, suicide is one of the most preventable health problems.

In honor of In honor of World Suicide Prevention Day , the National Institute of Mental Health (NIMH) will host a Twitter chat with Lisa Horowitz, Ph.D., M.P.H., on September 10, 2013, from 2–3 pm ET. Dr. Horowitz is a senior clinician on the Psychiatric Consultation-Liaison Service in NIMH’s Office of the Clinical Director. She recently developed a suicide screening tool that emergency department doctors and nurses can use to detect youth at risk for attempting suicide.

A Twitter chat is an organized event where people participate in an interactive conversation through tweets. The conversation usually focuses on a pre-arranged topic and specific tag (#) called a hashtag. Hashtags allow the conversation to be easily followed on Twitter. The chats are scheduled for a specific time and date, but are archived on this web page for viewing anytime. To participate, you will need a Twitter handle and account. If you prefer to simply observe the chat taking place, you may enter the specified hashtag at to view the conversation in real-time. Email us at if you have questions...and we’ll see you at our next Twitter chat!

You can find this discussion under #NIMHchats. An archive of the chat will be posted shortly after the event.
