Sequential Intercept Model

The Sequential Intercept Model originated with the criminal justice field in the early 1990’s and was developed to decriminalize mental illness. The adapted model, shown here, has been adapted for youth and young adults at Clinical High Risk for psychosis (CHR) by the SOC-CESS grant (2020).  By identifying sequential intercepts, or points of contact, strategic interventions can be provided at each intercept.  Providing strategic intervention results in improved clinical outcomes, and can reduce the need for more intense levels of services, such as hospitalization. 

Sequential Intercepts

Intercept 0 - Community

This is the first intercept in the Sequential Intercept Model. The members of this intercept include parents, school, pediatrician, and social services.

Intercept 1 - Medical/Behavioral Health

This second intercept includes Emergency Departments which ultimately lead to Behavioral Health Services.

Intercept 2 - Intervention

This part of the the model includes Screening, Assessment, and Treatment.

Intercept 3 - Ongoing Services

The final part of the Sequential Intercept Model includes Out-Patient Services, Residential Services, and Long Term Care.

Developmental Risk Factors

Within each intercept, there is a range of risk factors. You can see the risk factors for each intercept and age group below. You can also click the link below to download a handy chart with links to outside resources dedicated to each type of risk factor.

Developmental Risk Factors

Age Birth to 5

Developmental Risk factors at this age intercept include children having a genetic vulnerability, children who experience trauma, and family instability.

Age 6-11

Developmental Risk Factors at this age intercept include delayed development of social, language skills, anxiety, and depressive symptoms.

Age 12-17

Developmental Risk Factors at this age intercept include anxiety, depression, Autism Spectrum Disorder, suspiciousness, changes in perceptions, and decline in functioning.

Age 18+

Developmental Risk Factors at this age intercept include continued or sudden loss of skills, social interaction; increase in depression, anxiety, suspiciousness; First Episode of Psychosis.

Education and Support

Education and support in the following four fields impact development from Birth to 18+. Those four fields are: Medical Social Services Education Behavioral Health
