Réduire la durée de la psychose non traitée aux États-Unis : l'impact du dépistage et de la communication systématique (EaSIE)

In the SM condition all consecutive incoming patients ages 12-30 entering mental health services will complete a self-report screener, the PQ-B on intake. The intake clinician will review the PQ-B and refer all patients who endorse 6 or more items for evaluation with the SIPS to determine whether the patient meets criteria for psychosis, CHR, or neither. Evaluating clinicians will meet with patients to discuss findings and make referrals to specialty care as appropriate. The evaluating clinician will follow-up with patients referred to CSC and CHR programs to determine date of initial engagement. This information will be corroborated with records from CHR and FEP programs.

Evaluating clinicians will meet with patients to discuss findings and make referrals to specialty care as appropriate.

In the SCM condition, the same screening and evaluation procedures described above will continue, but clinicians conducting evaluations and making referrals will be trained to discuss findings and provide referrals using the ComPsych model. Following the evaluation, the clinician who conducted the evaluation will schedule a session with the patient, their family, and their treatment team (as applicable) and use the ComPsych model to discuss the findings of the evaluation, provide psychoeducation, and make referrals to specialty FEP or CHR services, as appropriate. The evaluating clinician will follow-up with patients referred to CSC and CHR programs to determine date of initial engagement. This information will be corroborated with records from CHR and FEP programs.

Clinicians will be trained to discuss findings and provide referrals using the ComPsych model. ComPsych prepares clinicians to effectively communicate diagnostic, prognostic and treatment information about FEP and CHR with patients and families, using a model that instils realistic hope and provides information effectively to encourage shared decision making about treatment.

The DUP is defined as the time, in weeks, between onset of psychotic symptoms (measured by the Symptom Onset in Schizophrenia Scale) and initiation of FEP treatment (date of intake into Coordinated Specialty Care (CSC) programs for first episode psychosis.

The DUI is defined as the time, in weeks, between onset of psychotic symptoms (measured by the Symptom Onset in Schizophrenia Scale) and evaluation with the SIPS.

Number of individuals initiating FEP services

Number of individuals initiating CHR services

This 22-item measure uses a 5-point Likert scale to measure satisfaction with amount/quality of information presented, emotional support and level of patient and family participation. The PSC has high internal reliability (Cronbach's Alpha .91). Used extensively in cancer studies, it is sensitive to differences in consultant behavior. For the purposes of this study, 4 items were removed. PSC will be administered to patients and family members in both SCM and SM conditions after a consultation where SIPS feedback is provided and referral made (in SCM ComPsych model will be used).

Full scale from 18 - 90, with higher score indicating greater satisfaction

A self-report scale adapted from the Knowledge About Schizophrenia Test (KAST) to assess understanding of psychosis. KAST is an 18 item instrument, full scale range from 1-18, higher score indicates more knowledge.

28-item Stigma Scale (SS) Full scale from 28 - 140, higher score indicates higher impact of stigma

Patients will be asked how much they agree (on a 5-point likert scale) with the statement: "I intend to go to my initial appointment at [name of program referred to]" Score from 1-5, with higher score indicating more agreement.

Patients will be asked how much they agree (on a 5-point likert scale) with the statement: "I think [program] is likely to help me with my problems". Score from 1-5, with higher score indicating more agreement.
