Ambulatory assessment for precision psychiatry: Foundations, current developments and future avenues

Area of Science:

• Psychiatry
• Digital Health
• Behavioral Science

Background:

• Precision psychiatry aims to personalize mental healthcare using individual-specific data.
• Understanding dynamic psychological processes in everyday life is crucial for effective treatment.
• Current methods often lack real-world, contextual data on patient experiences.

Purpose of the Study:

• To review the role and potential of ambulatory assessment in advancing precision psychiatry.
• To highlight how digital technologies can capture real-life data for mental health insights.
• To explore the application of ambulatory assessment in psychiatric research, diagnosis, and treatment.

Main Methods:

• Ambulatory assessment combines repeated self-reports (e.g., smartphone diaries) with sensor data (e.g., accelerometers, GPS, ECG).
• It monitors behavioral, physiological, and environmental factors in participants' natural settings.
• Ecological Momentary Assessment (EMA) is a key component for real-time data collection.

Main Results:

• Ambulatory assessment provides a dynamic, contextual view of mental states and symptomatology.
• It offers opportunities for predicting disorder trajectories, identifying relapse risks, and evaluating treatment effects.
• Digital technologies facilitate the collection of rich, multi-modal data from daily life.

Conclusions:

• Ambulatory assessment is a vital tool for precision psychiatry, offering new research and clinical possibilities.
• It supports personalized care by providing real-time feedback and tailored interventions.
• This methodology promises significant advancements in psychiatric diagnosis, prevention, and treatment.
