The current study is a multicentre, longitudinal cohort study on recovery from psychotic disorders. The research population will consist of clients who receive treatment for a first episode psychosis or have a diagnosis of schizophrenia or another psychotic disorder (schizoaffective disorder, delusional disorder, or psychosis not otherwise specified) and who are between 18 and 65 years old. They will be recruited at different mental health care centers in the Netherlands, in various teams specialising in in- and outpatient care for severe mental illnesses. All primary and secondary outcome measures will be assessed every year. All other questionnaires and procedures will be repeated every 2 years, with the last measurement 10 years after baseline.

Recruitment is ongoing
