The training is targeted to mental health providers working with young people at high risk for psychosis or cases of first episode psychosis. The Structured Interview of Psychosis-risk Syndromes (SIPS) is a structured interview for diagnosing a clinical high risk (CHR) syndrome for psychosis and cases of first episode psychosis (McGlashan et al., 2010). It contains a severity rating scale (the Scale Of Psychosis-risk Symptoms, or SOPS), a well-anchored Global Assessment of Functioning (GAF) (Hall, 1995), the DSM-IV schizotypal personality disorder checklist, a brief assessment of the family history of psychosis, and the Criteria Of Psychosis-risk Syndromes (COPS) and Presence Of Psychosis Scale (POPS) and DSM-5 Attenuated Psychosis Syndrome criterion sets.
