In Module 1, participants gain an understating about how early attachment experiences impact one's later expectations for safety in the world, trust in and protection from others, and self-worth. Participants will learn to identify different attachment styles and how to apply the attachment principles of proximity maintenance, attunement, safe haven and secure base in the context of their interactions with girls to improve engagement, and build stronger, more secure therapeutic relationships. Attention is also paid to the role of insecure attachment in intimate partner violence and domestic minor sex trafficking.
