Impact of Containment and Quarantine During COVID-19 Outbreack on Psychotic Symptoms in the General Population in France

The pandemic of the novel coronavirus disease (COVID-19) has now affected millions of people, including people in France. There are reports in the media about increased stress, anxiety and isolation for the entire population. Likewise, there are many concerns regarding people with mental health issues including people experiencing psychotic symptoms. Thus, studies are needed to understand better the effects of the COVID-19 pandemic and related government measures (e.g., self-isolation) on the mental health and specifically on psychotic experiences. To reach this aim the investigators designed an online survey evaluating people's perceptions of the COVID-19 pandemic and government measures, their habits during the isolation period, to what extent they feel lonely, how they are managing their emotions, their general emotional state and finally the presence of psychotic experiences. Participants will be invited to complete these measures three times. Participants will complete the survey again in 1 week and then in 1 month.

The specific goals of this project are:

• Determine the association between psychotic symptoms (paranoia and hallucinations) and perception of the COVID-19 pandemic and government measures, level of activity, isolation, emotion regulation, cognitive bias and negative affect at Time 1.
• Determine which factors predict psychotic symptoms one week later and one month later.
• Explore changes across time on these measures.

Methodology:

The entire study will be conducted online. Participants will be assessed at baseline_ T1: Peak of the COVID-19 pandemic; T2: 1 week after T1; T3: 1 month after T1.
