The Self Screen Prodrome is used to differentiate between healthy patients, patients with psychosis (risk) and other ICD-10 diagnoses in an initial screening phase. It was developed within the FePsy (= early detection of psychosis) study and comprises 32 items. Reliability: Cronbach's alpha was at alpha = .90 (total), alpha = .89 (patients) and alpha = .75 (healthy). Validity: Psychosis (risk) patients as well as patients with other ICD-10 diagnoses could be differentiated relatively well from healthy individuals on the basis of the overall scale. For the comparison between patients and healthy persons, a cut-off value > = 6 resulted in a sensitivity of more than 85% and a specificity of more than 81 %. At the level of individual items it was shown that psychosis (risk) patients, compared to healthy persons, stated significantly more frequently that all symptoms had newly appeared in recent years. When comparing psychosis (risk) patients with patients with other ICD-10 diagnoses, significant differences were found in six individual items, which were combined to form the subscale "psychosis risk". In terms of predictive validity, the SPro was found to predict the psychosis-like symptoms of SCL-90-R better than the Eppendorf Schizophrenia Inventory. The convergent validity of the SPro overall scale was confirmed by a high correlation with the SCL-90-R Global Severity Index.
