This finding came as a surprise to the lead researcher, Ian Kelleher, M.D., Ph.D., a research fellow with the Royal College of Surgeons in Ireland. He told Psychiatric News, "While we knew that people with psychotic disorders are at high risk of suicidal behavior, we did not know that there was such a strong relationship between psychotic experiences (which are much more common than psychotic disorders) and suicidal behavior in the population."
"This is a very interesting study," said child and adolescent psychiatrist Kayla Pope, M.D., of Boys Town National Research Hospital in Nebraska, in an interview. "We need better markers for assessing suicide risk, and the finding in this study is an important step in that direction."
