What this trial studies

This research aims to explore how social isolation and loneliness are connected to neurobehavioral mechanisms in individuals with serious mental illnesses, such as psychosis and schizophrenia. By utilizing advanced neuroimaging and smartphone-based assessments, the study will examine the dynamic interactions of these experiences in daily life and their impact on functioning. The findings could lead to new therapeutic targets to improve the quality of life for those affected by serious mental illnesses.

Not a fit: Patients with neurological disorders, current substance use disorders, or those not proficient in English may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new treatments that enhance daily functioning and overall quality of life for individuals with serious mental illnesses.

How similar studies have performed: Previous studies have indicated correlations between social isolation, loneliness, and mental health, but this approach is novel in its use of advanced neuroimaging and dynamic assessments.
