This training will provide an overview of the causes and contributing factors related to hoarding disorder. Participants will be introduced to evidence-based approaches for addressing hoarding disorder for clients within a variety of contexts, including those who are housed and unhoused. A trauma informed, harm-reduction approach -` Safety Day’ (Sampson & Yeats, 2015)- for preventing evictions for people experiencing hoarding disorder will also be presented. Participants will explore contextual features of hoarding disorder in order to consider ways to leverage supports and resources effectively.
