Culturally-Adapted Family Intervention Study (CaFI)

Culturally-adapted family intervention for African and Caribbean people diagnosed with psychosis, and their families.



Are you a Black and Mixed heritage person diagnosed with schizophrenia or psychosis, or their relative?

We are currently recruiting participants living in specific parts of England for a study. The study will see if a new kind of talking therapy helps Black and Mixed heritage people diagnosed with schizophrenia or psychosis and their families.

Find out more about the study, if you are eligible to take part, and how to sign up.

Taking part in the CaFI study

We are looking for eligible people to join our study to see whether Culturally-adapted Family Intervention (CaFI) is effective for Black and Mixed heritage people diagnosed with schizophrenia or psychosis and their families.

CaFI was designed together with service users, their families, community members, and health professionals for people from African-Caribbean backgrounds diagnosed with psychosis.

We are offering CaFI to 202 families of Caribbean and Sub-Saharan African origin across the north-west, Midlands, south-east and London as part of a randomised controlled trial (RCT).

We will compare their results with 202 families who do not receive CaFI to see if CaFI is at least as good as usual care.

Participants randomised to receive CaFI will receive talking therapy over ten sessions.

You can take part in the study if you meet our eligibility criteria. You may be referred to us by your clinical team, or you can get in touch with us to express an interest in joining the study.

CaFI:Digital will help reduce the impact of COVID-19 restrictions on the trial.

Originally, as with other FI models, CaFI was designed to be delivered in person. CaFI will now be delivered face-to-face/in person, or via CaFI:Digital – a bespoke online platform that we have developed to increase patient choice and flexibility.

If family units opt to receive CaFI:Digital, the therapy sessions will be delivered via Microsoft Teams. Therapists will direct family units to resources located on the purpose-built, secure CaFI:Digital website.
