This clinically wise and pragmatic book presents a systematic approach for treating any form of childhood anxiety using proven exposure-based techniques. What makes this rigorously tested modular treatment unique is that it is explicitly designed with flexibility and individualization in mind. Developed in a real-world, highly diverse community mental health context, the treatment can be continually adjusted to target motivational problems, disruptive behavior, family issues, and other frequently encountered clinical roadblocks. In a large-size format for easy photocopying, the book includes a detailed case formulation framework, a flexible treatment planning algorithm, and over 90 pages of user-friendly reproducible tools.
