New Bizarre Method Of Predicting Psychosis Introduced

Psychosis is known to be a very sensitive topic as it affects a lot of people and it is a condition wherein someone may experience series of mental torture. Psychosis is always misunderstood by a lot of people because it is too complicated and difficult to explain. But that will be changed now since a new computer program can now predict the disorder by just analyzing your speech patterns.  

“Psychosis is an abnormal condition of the mind described as involving a “loss of contact with reality”. People with psychosis are described as psychotic. People experiencing psychosis may exhibit some personality changes and thought disorder. Depending on its severity, this may be accompanied by unusual or bizarre behavior, as well as difficulty with social interaction and impairment in carrying out daily life activities.” - Wikipedia

The recent research which was participated by 34 young people who went with numerous computer testing for their language patterns’ semantic coherence during an open-ended, narrative interview. The speech tests were held quarterly over a period of 2.5 years. The program showed a 100 percent success rate in differentiating the five people who eventually experienced a psychotic episode versus the 29 who did not. Humans only have a 79 percent success rate of predicting whether a person will develop psychosis, very unlikely for the computer's success rate in determining if a person can develop the condition.

The study was conducted by researchers at Columbia University, the New York State Psychiatric Institute, and the IBM T.J. Watson Research Center. They used an automated speech analysis program which managed to correctly predict the young people who would develop psychosis. The speech characteristics which predicted psychosis includes breaks in the flow of meaning from one sentence to the next, and speech characterized by shorter phrases with less elaboration.

“When people speak, they can speak in short, simple sentences. Or they can speak in longer, more complex sentences, that have clauses added that further elaborate and describe the main idea, The measures of complexity and coherence are separate and are not correlated with one another. However, simple syntax and semantic incoherence do tend to aggregate together in schizophrenia,” -  Guillermo Cecchi, a biometaphorical-computing researcher for IBM Research

During the 45 minutes of interviewing, those people who underwent the test and was found out to develop psychosis had at least one occasion of a “jarring disruption” in meaning from one sentence to the next. This method could also be able to identify thought disorder in its earliest form which could also open up possibilities for intervention.

“If speech analyses could identify those people most likely to develop schizophrenia, this could allow for more targeted preventive treatment before the onset of psychosis, potentially delaying onset or reducing the severity of the symptoms which do develop,” - Gillinder Bedi, an assistant professor of clinical psychology at Columbia University
The researchers plans to replicate their findings using a larger cohort of at-risk youths.
