Description

Andrea Imparato and co-authors study how positive and negative symptoms of psychosis interact over time, using phone-based momentary tracking. Standard interviews look backward and miss short-term shifts in symptoms and context. The team applies a method called Behavioral Tractography to people with 22q11.2 deletion syndrome, a group at high risk for psychosis. Momentary assessments record symptoms in real life, many times over days.

After reducing the network's complexity, the authors find that the momentary patterns mirror the symptom structure from gold-standard interviews. This suggests shared mechanisms and supports the tracking method as valid. The approach also dissects how psychotic symptoms and motivational deficits influence each other, shaped by overall severity. It separates patients with mostly positive profiles from those with mostly negative ones. Vulnerability to later effects varies apart from average symptom level, adding value beyond standard assessment.
