Schizophrenia
About 20 minutes every four weeks, on any phone or computer. How you feel, what you notice, how the medicine is treating you and how life is going, kept as one dated record.
What this adds up to
People stop treatment for reasons that can be measured. Sensus measures them every four weeks, in the person’s own words and a family member’s, and puts them in front of the clinician, so the conversation about a medicine can happen before the decision to stop it.
Two people leave the same clinic with the same diagnosis and the same new prescription. A year later, one is still taking it and doing better. The other stopped in the third month. Nothing was wrong with the medicine. It was the weight, the restlessness and the sense that it wasn’t helping, which nobody wrote down until the next crisis made them impossible to miss.
74%
of 1,493 people in the largest US comparison of antipsychotics stopped their assigned medicine within 18 months.
CATIE, NEJM 20051Side-effects
and the sense that a medicine isn’t working were common reasons for stopping. So were lack of insight into the illness and substance use.
CATIE; Higashi et al. 20132Relapse
Stopping is linked to a greater risk of relapse, hospitalization and suicide.
Higashi et al. 20132What is missing between appointments is not a test. It is a record: how the person is sleeping and feeling, what the medicine is costing them, whether they are still taking it, and how life is going, written down at the time instead of remembered months later.
Sensus keeps that record. Every four weeks, a short set of published questionnaires is saved as one dated sitting. Each time, the person’s answers are compared with their own starting point. A family member can add their view of how everyday life is going. The clinician sees the same record.
None of it is a diagnosis. What it shows, month after month, is direction: what is improving, what is getting harder, and whether the reason is the illness, the medicine or something else.
Step 1
About 20 minutes every four weeks, on any phone or computer, at home. A family member answers a few questions of their own each quarter.
Step 2
A plain-language report the moment you finish, showing how each part has moved since you began.
Step 3
Take the report to your clinician. What to change, if anything, is decided between you.
Published questionnaires, used unaltered and scored the way their authors published them. Instruments still awaiting permission are marked pending and are not yet in use.
Senses
Voices, suspicious thoughts, unusual experiences.
Feelings
Mood, anxiety, bipolar signs and trauma. A question about suicide brings up the 988 line at once.
Awareness
How you see your symptoms, the illness and the treatment.
Function
Self-care, getting around, people, work and taking part, from you and from someone close to you.
Body
Side-effects, pain and sleep.
Treatment
Your medicines and whether doses are being taken. No doses are ever shown.
Context
Whether you are answering from home, and substance use.
Every questionnaire is used unaltered and scored the way its authors published it. The science page sets out what each one measures, how it is scored, and whether it has been studied over time and in schizophrenia.
AUC 0.953
The R-GPTS paranoia scale identified persecutory delusions in patients with psychosis with this accuracy.
Freeman et al., Psychological Medicine 2021Detects change
The WHO’s WHODAS 2.0 is validated in schizophrenia, and its family version is the more sensitive to change in serious mental illness.
Guilera et al. 2012; Koopmans et al. 2020Every card
Each instrument is labelled for whether it has been shown to work when repeated, and whether it has been studied in schizophrenia.
