Patients with schizophrenia often experience fragmented time and distorted spatial perception, such as abnormal interpersonal distance and orientation, which can detach them from reality and complicate therapy. Despite this, these experiences remain understudied due to a lack of standardized measurement tools. Based on spatiotemporal psychopathology (STPP), a clinical rating scale called the Scale for Space and Time Experience in Psychosis (STEP) was developed. The German version of STEP assesses 14 spatial and 11 temporal phenomena across 25 items. It demonstrates high internal consistency (Cronbach's alpha = 0.94) and significant correlation with the Positive and Negative Syndrome Scale (PANSS; p < 0.001), offering a valuable instrument for German-speaking countries.
