Book excerpt: This important new text provides a framework for occupational therapists and occupational therapy assistants that can be applied in all children and youth practice settings. The content lays a foundation for conceptualizing the role of occupational therapy in mental health promotion, prevention, and intervention when working with children and youth-those with and without disabilities, mental illness, or both-in schools and community settings. Reflecting a public health approach to occupational therapy services at the universal, targeted, and intensive levels, the emphasis is on helping all children develop and maintain positive affect, positive psychological and social functioning, productive activities, and resilience in the face of adversity.
