Thermoregulation Among Individuals With First-episode Psychosis

Withdrawn

• Conditions: Psychosis; First Episode Psychosis

• Registration Number: NCT04369677
• Lead Sponsor: Nicholas Breitborde

Brief Summary

The project will evaluate thermoregulatory processes among individuals with and without first-episode psychosis.

Detailed Description

The project will evaluate thermoregulatory processes among individuals with and without first-episode psychosis.

Aim 1: Assess whether individuals with first-episode psychosis have differences in mean temperature and diurnal temperature variation as compared to individuals without psychosis.

Aim 2: Examine whether mean temperature and temperature variation during periods of rest and activity are different between individuals with first-episode psychosis versus people without psychosis.

Aim 3: Explore the association between current core body temperature and current ratings of psychotic symptomatology among individuals with first-episode psychosis.

Study participants will complete baseline assessments (e.g., symptoms, functioning, and sleep) and then complete a 24-36 hour ambulatory assessment period in which core temperature, activity, sleep, and heart rate variability will be tracked continuously and symptom severity will be assessed sporadically using a symptom rating app on their smart phone. .Then they will complete a second study visit to repeat baseline assessments.
