Exploring the prevalence and interplay of adverse childhood experiences, chronic homelessness and factors of multiple exclusion, within a single adult homeless population living in hostel accommodation in Northern Ireland

Analysis included descriptive and inferential statistics, non-parametric testing, and Two-Step Cluster Analysis.<br><br>Findings identified high levels of adversity and exclusion within the sample. Overall, 66.3% of participants reported four or more ACEs, while 88.6% met the threshold for MEH. Higher ACE exposure was significantly associated with institutional contact, violence, mental health difficulties, and experiences of homelessness.

Cluster analysis identified four distinct profiles of exclusion, demonstrating substantial variation within the hostel population and highlighting differing levels of need and vulnerability.<br><br>The study contributes new evidence on the relationship between childhood adversity and multiple exclusion among adults experiencing homelessness in Northern Ireland. It advances understanding of homelessness as a cumulative process shaped by interconnected social and structural disadvantages.

The findings support the development of trauma informed, preventative, and cross sector responses that address the broader causes of homelessness across the life course.
