Note. Parental education is the average of mother and father education. Automated analysis frames detected indicate the total percent of time in which the automated analysis tool was able to register the video recording of the face. The Beck Depression Inventory (BDI) represents a total sum score. Social functioning scores are given on a 1–10 scale, with 1 indicating low levels of social functioning and 10 very high levels. Psychosis risk scores represent psychosis risk conversion calculator scores (signaling heightened likelihood of conversion to psychosis in 1 year). Symptom domains are sum scores of items for positive and negative symptoms from the Structured Interview for Prodromal Syndromes (SIPS).
