Implementation phase. If the PQ-16 is positive, patients can be addressed in the EIS and will be screened for the CHR-P criteria by the EIS; patients who are negative in terms of the PQ-16 or according to CHR-P criteria would be referred to the original source. For CHR-P + patients, a pretest calculator should be applied to determine whether they require specialized treatment in the early intervention program. CHR-P at low risk based on the risk calculator will be referred back to the original source with a specific treatment recommendation. All the patients with an ARMS will be assessed using a multiaxial assessment battery with specific follow-ups to monitor the possible conversion to psychosis and to update the team in charge concerning the treatment recommendations (for more details see Table A1, Appendix A).
