# Can Ecological Momentary assessments be used to investigate the person-environment interactions in people with psychosis?

## TL;DR

This paper explores using real-time assessments to study how people with psychosis interact with their environment.

## Contribution

It introduces using Ecological Momentary Assessment to study dynamic symptom patterns and deliver psychological treatment in daily life.

## Key findings

- EMA can capture dynamic patterns of positive and negative symptoms in daily life.
- The INTERACT trial tested Acceptance And Commitment Therapy in daily life for early psychosis.
- EMA can help transfer psychological treatments to real-world settings.

## Abstract

Psychotic experiences show a dynamic pattern over time, often in interaction with the environment. In my talk, I will discuss how Ecological Momentary Assessment (EMA) or Experience Sampling Methodology can be used to assess psychotic symptoms in the flow of daily life. I will focus on the assessment of both positive and negative symptoms, where I will discuss both how we can measure such symptoms as well as what the dynamic patterns look like in everyday life. Furthermore, I will also focus on how ESM can be used to transfer psychological treatment to daily life using an app. I will discuss the INTERACT trial, a trial in people at the early stages of psychosis, where we investigated the effect of Acceptance And Commitment Therapy in Daily Life, compared to Treatment As Usual.
