Homelessness and Prevalence of Neurodevelopmental Disorders

Recruiting now · Not applicable

Conditions studied: Neurodevelopmental Disorders

In brief

Introduction \& Central question: Psychiatric disorders are highly prevalent in the homeless population, however neurodevelopmental disorders are also at risk of leading to homelessness (Churchard et al., 2018; Casey et al., 2020). Research on this topic is poor in France. This research aims to study the prevalence in France of 3 neurodevelopmental disorders (NDDs) in a homeless population (Autism Spectrum Disorder, Attention Deficit Hyperactivity Disorder and Intellectual Developmental Disorder). Methods / approach: A 2 phase approach will be used including a screening phase and a diagnosis phase. This research is a pilot study that will include 150 homeless people, over 2 years. The assessment involves combining the results from standardised self-report tools, direct observation and informant-report, thus guaranteeing an objective and thorough diagnosis. This approach gives a better picture of actual behaviour but also a better understanding of the person's development. OUTCOME: This study will give insight on how to better understand the profile of the homeless population in France, and the prevalence of autism in this population. It will also bring valuable knowledge on how autism and other NDDs can impact one's path in life and lead to homelessness. The results can help develop targeted cares and measures for homeless people with NDDs.
