A unique program to prevent and treat psychoses  (PEPP-Montréal)

Untreated first episode of psychosis

The Prevention and Early Intervention Program for Psychosis (PEPP-Montréal) is a program for young people who are experiencing an untreated first episode of psychosis. PEPP-Montréal’s goal is to spur hope for full recovery in adolescents and young people suffering from psychosis.

“Early intervention” in psychosis is a relatively new concept in mental health. It is designed to improve outcomes in schizophrenia and other psychoses. To reach this goal the program aims to earlier detection of untreated psychosis and effective treatments tailored to the specific phases of the disorder.

PEPP-Montréal accepts people:
Between the ages of 14 and 35
▪ With an affective or non-affective psychotic disorder

The participants:
▪  have never been treated for psychosis or have taken anti-psychotic medication for no more than 30 days
▪  do not suffer from organic brain damage, pervasive developmental disorder, mental retardation or epilepsy
▪ are not forensic patients

Quick assessment and full medical and psychosocial treatment

It can be difficult for young people and their families to detect the early stages of psychosis. However, it is essential for psychotic disorders to be diagnosed and treated quickly. This diagnostic improve the chances of recovery and avoid delays in treatment.

This is why PEPP-Montréal offers a thorough assessment of psychotic symptoms by trained professionals. Families are invited to take part in the assessment process. If a patient is identified as very likely suffering from a psychotic disorder, a psychiatric assessment interview with a psychiatrist is arranged.

If the psychotic disorder diagnosis is confirmed, a case manager is assigned to the patient. The case manager will be the primary contact person. With the program psychiatrist, the case manager will take responsibility for the person’s care for the duration of the program.

PEPP-Montréal team regularly evaluates the effectiveness of the treatment it provides.  The professionals regularly monitors symptom severity, personal and family goals and satisfaction with services through interviews and self-rating scales. Learn more about the treatments.

Research and clinical service go hand in hand

Research is an important and integral part of PEPP-Montréal. Through research activities in the program, clients and their families benefit from new knowledge. The results of the research result in state-of-the-art diagnostic and treatment methods for the early stages of psychosis.

PEPP Housing Project

Launched in 2014, the housing project is aimed at adults in the PEPP program who are experiencing residential instability, have little experience in apartments and wish to develop independence.

The recruited participants choose their own apartment, usually furnished. They gradually contribute to the rent costs by paying between 25% and 80%, the rest being subsidized. Once arranged, youth receive regular visits from clinical staff at home (in addition to outpatient follow-up), as well as assistance from a counselor to facilitate their return to work or school.


Since January 2014; 36 participants have joined the project. Thirteen of them have completed their course; seven of the young people still live at the same rent, while twelve are in PEEP housing. (October 2018)

  • 78% of the young people in the project were able to study or work during their participation.
    50% of young people have met a professional to help them return to school or enter the job market.
    Nearly 40% of the participants resumed their medical follow-up following their acceptance into the project.
