Psychiatric Thought Disorder Detection by Quantum Resonance Spectrometer Applied to Psychotic Symptom- Based Objective Diagnosis

To evaluate reliability and psychiatric clinical value of Quantum Resonance Spectrometer (QRS) in thought disorder detection, as psychotic symptombased objective diagnosis. We studied 1014 schizophrenic patients, 155 patients with bipolar disorders patient, and 100 normal controls. Thought disorder symptoms of same subjects obtained from QRS test and psychiatrists' diagnoses were compared. Also thought disorder symptoms of renumbered 65 schizophrenia patient and 100 normal controls were discriminated using QRS test. Kappa values were more than 0.65 in 6/9 symptoms of schizophrenia, and more than 0.74 in all 3 symptoms of bipolar disorder. Same consistency could also be seen in Pearson R value, and ROC AUC. In the discriminated analysis, sensitivity, specificity, positive predictive value and negative predictive of delusion, looseness of thought and paralogism thinking detected utilizing QRS are more than 0.70 compared with psychiatrists' diagnoses. In summary, QRS is a predictor of psychiatric thought disorders, and an objective identification and diagnosis instrument. Psychiatric thought disorder detection by QRS could be applied to psychotic symptom-based objective diagnosis.
