About this study
The guiding questions for this study are: can a U.S. adaptation of a successful Scandinavian approach (TIPS) to early detection substantially reduce the duration of untreated psychosis (DUP) and improve outcomes beyond an established first-episode service (FES)?
The primary aim of this study is:
- To determine whether an early detection intervention can reduce DUP in the US, as compared to usual detection. Early detection (ED) will be implemented in one US community (New Haven, CT), and usual detection efforts will continue in another (Boston, MA). DUP will be measured at admission to the corresponding first-episode services (STEP \& PREP) in each community, over one year before and throughout ED implementation. The investigators hypothesize that DUP will be reduced significantly in the early detection site compared to the usual detection site;
- A secondary aim is to determine whether DUP reduction can augment the outcomes of established FES on outcomes in the U.S. The investigators will measure symptoms, functioning and engagement with treatment at entry and over 1 year at each site. The investigators hypothesize that shorter DUP at one FES (STEP) will predict reduced distress and illness severity at entry and better early outcomes at STEP compared to PREP.
Read the detailed description
Early detection, or reducing the duration of untreated psychosis (DUP) can substantially ameliorate the distress and disability caused by psychotic illnesses. The TIPS project in Scandinavia used a combination of public and targeted education campaigns coupled with rapid availability of comprehensive services to improve the identification, referral and early treatment of psychotic illness. By targeting the dual 'bottlenecks' of inadequate mental health literacy and delayed access to effective treatment, TIPS significantly reduced DUP2 and experimentally demonstrated improved clinical presentations and outcomes.
Effective service models for new onset psychosis exist in the U.S. Multi-element specialty 'first-episode' services (FES), highlighted in this FOA, provide care that is adapted to the specific needs of younger patients and their families and can improve symptoms and functional outcomes during the critical early phase of psychotic illnesses. The NIH-funded Specialized Treatment in Early Psychosis (STEP, New Haven) project, included the first U.S.-based randomized controlled trial to establish the feasibility and effectiveness of a public-sector approach to FES.5 The Prevention and Recovery in Early Psychosis (PREP, Boston) clinic has advanced a similar model of care within an analogous public-academic collaboration.
What is required, as the next logical step, is a test of the effectiveness of TIPS' powerful approach to early detection in a policy-relevant U.S. setting, where relatively fragmented pathways to care raise both the challenges and potential public health impact of early detection. The expertise within the investigators investigative team in the design of early detection and the presence of 2 similar, effective, geographically separated and collaborative FES programs (STEP and PREP) presents an excellent opportunity to conduct such a test and thereby advance secondary prevention for psychotic illnesses in the U.S.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Early Detection (ED)Behavioural
This intervention consists of educational campaigns directed at patients \& families (who have yet to seek care) and professionals in educational and clinical settings to hasten referral of individuals with new onset psychosis to an established, best-practice first-episode service (i.e. STEP). Interleaved with this educational campaign will be procedures to make the STEP clinic more rapidly responsive to referrals to further shorten the duration of untreated psychosis
Usual DetectionBehavioural
This intervention will provide equivalent best practice care without the benefit of an early detection campaign

What is being measured
The primary outcome is the main question the study is designed to answer.
Duration of Untreated Psychosis (DUP)
Time from onset of psychosis to first antipsychotic (DUP-Demand); Time from first antipsychotic to enrollment in STEP/PREP (DUP-Supply); Time from onset of psychosis to enrollment in STEP/PREP (DUP-Total)
Measured: One year before, during campaign and one year after end of campaign
Secondary outcomes (3)
Levels of social and occupational functioning
A trained assessor will administer the positive and negative syndrome scale (PANSS) scale to every subject for levels of social and occupational functioning. The PANSS is a medical scale used for measuring symptom severity of participants with schizophrenia. The PANSS rating form contains 7 positive symptom scales, 7 negative system scales, and 16 general psychopathology symptom scales. Participants are rated from 1 to 7 on each symptom scale. The total score is the sum of all scales with a minimum score of 30 and a maximum score of 210.
Measured: 1 year after enrollment in STEP/PREP
Change in levels of social and occupational functioning- social
The Global Functioning: Social scale will be used, with symptoms rated 1 (most impaired) to 10 (superior functioning).
Measured: 6 months and 12 months
Change in levels of social and occupational functioning- roles
The Global Functioning: Role scale will be used, with symptoms rated 1 (most impaired) to 10 (superior functioning).
Measured: 6 months and 12 months

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The guiding questions for this study are: can a U.S. adaptation of a successful Scandinavian approach (TIPS) to early detection substantially reduce the duration of untreated psychosis (DUP) and improve outcomes beyond an established first-episode service (FES)?
The primary aim of this study is:
- To determine whether an early detection intervention can reduce DUP in the US, as compared to usual detection. Early detection (ED) will be implemented in one US community (New Haven, CT), and usual detection efforts will continue in another (Boston, MA). DUP will be measured at admission to the corresponding first-episode services (STEP \& PREP) in each community, over one year before and throughout ED implementation. The investigators hypothesize that DUP will be reduced significantly in the early detection site compared to the usual detection site;
- A secondary aim is to determine whether DUP reduction can augment the outcomes of established FES on outcomes in the U.S. The investigators will measure symptoms, functioning and engagement with treatment at entry and over 1 year at each site. The investigators hypothesize that shorter DUP at one FES (STEP) will predict reduced distress and illness severity at entry and better early outcomes at STEP compared to PREP.

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Duration of Untreated Psychosis (DUP) (time frame: One year before, during campaign and one year after end of campaign). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02069925, which also lists 21 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Apr 2022; AzTrials last refreshed its copy on 7 Nov 2026.
