A 20-Year Follow-up of First Episode Psychosis: Longitudinal Effects of Early Treatment Strategies and Relapse
China178 participantsStarted 2026-05-21
Plain-language summary
The study aims to address the following questions:
1. Do subgroups defined by early medication choices, relapse, and medication taken over 20 years differ in clinical, cognitive, and functional outcomes?
2. What are the long-term cognitive functioning trajectories, what factors predict these trajectories, and how do they relate to outcomes?
3. What might be the mechanisms behind medication discontinuation and poor long-term outcome, including the roles of multiple relapses and treatment resistance after first-episode psychosis?
Eligible patients will be invited to a one-time face-to-face interview. A trained research assistant will guide the participants through questions about their background, clinical symptoms, daily functioning, cognitive abilities, and psychological well-being.

Participants were individuals who previously participated in a randomized controlled trial investigating medication continuation/discontinuation on relapse during first episode psychosis (ClinicalTrials.gov NCT00334035). The trial included specific inclusion and exclusion criteria, detailed as follows:
Inclusion Criteria:
* A diagnosis of schizophrenia or non-affective psychosis (schizophreniform disorder, schizoaffective disorder, brief psychotic disorder, or psychosis not otherwise specified) (DSM-IV)
* Aged 18 to 65 years at the time of original enrolment
* Had been treated with antipsychotic drugs for at least 12 months
* No history of relapse or exacerbation or had to be asymptomatic (free of positive symptoms of psychosis) at study entry.
Exclusion Criteria:
* A diagnosis of drug-induced psychosis
* Current treatment with clozapine, with mood stabilizing medications (lithium, valproate or carbamazepine) or with depot medication
* Had high risk of suicide or violence
* Inability to provide informed consent at recruitment
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
