Yoga-based group program plus usual care for outpatients with schizophrenia spectrum disorders
Official title: Feasibility, Acceptability, and Preliminary Efficacy of Yoga-based Group Intervention for Outpatients With Schizophrenia Spectrum Disorders (YOGIA Study) - a Three-arm, Single-blind Randomized Controlled Pilot Study
Run by Charite University, Berlin, Germany · NCT07455929 · Data updated 2026-11-12
This project will see if a 12-week yoga-based group program added to usual outpatient care helps adults with schizophrenia spectrum disorders reduce stress and symptom-related distress compared with exercise or usual care alone.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are psychiatric outpatients aged 18–65 with a diagnosed schizophrenia spectrum disorder who can give informed consent, participate in group therapy, and have low-to-moderate positive symptoms (PANSS positive items ≤6).
✕Probably not a fit
Patients with very severe psychotic symptoms (PANSS item >6), acute suicidality, acute substance dependence, major neurological injury, or inability to join group sessions are unlikely to benefit or be eligible.

What this trial studies
A three-arm, rater-blinded randomized pilot in Berlin compares a yoga-based group intervention plus treatment as usual (YoGI + TAU) to strength and flexibility training plus TAU (SFT + TAU) and to TAU alone. Participants are psychiatric outpatients aged 18–65 with a schizophrenia spectrum diagnosis and low-to-moderate psychotic symptoms, randomized in blocks and informed of group allocation after randomization. Self-report and blinded clinician ratings are collected at baseline, after 12 weeks, and at a 3-month follow-up, and acute stress and perceived effort are measured before and after each session. Recruitment, consent, and assessments are managed by blinded psychologists at Charité and participants receive €50 upon completion.
Why it matters
Potential benefit: If successful, this could offer a low-cost, group-based option to reduce acute stress and symptom-related distress and support daily functioning for outpatients with schizophrenia spectrum disorders.
How similar studies have gone: Previous small trials of yoga for schizophrenia and related disorders have shown promising stress and symptom reductions but the evidence is still limited and mixed.
