Home, school, and out-patient mental health settings are all covered in detail, as well as dyadic and group forms of Theraplay. Client issues include interpersonal violence, LGBTQ families, anxiety, child sexual abuse, transitioning from foster care to adoption, and deaf and hard of hearing. Additionally, extensive information is provided about working with caregivers including discussion of their own attachment history, practice sessions before including the child, and regular caregiver-only sessions to process and strengthen Theraplay treatment.
