The term "behavioral health and wellness" refers to a strengths-based approach to health that involves the mental, physical, social, and emotional well-being of individuals. Families that are experiencing behavioral health and wellness issues have more contact with the child welfare system as the resulting instability can affect the safety and well-being of all family members. Child welfare systems are impacted greatly by these wellness concerns, particularly substance use disorders and mental illness. In response, the child welfare system must collaborate across systems and comply with Federal legislation in order to best serve families.
