This paper outlines the preparations necessary for state psychological associations to make a timely, well-coordinated, and successful mental health response to disaster or trauma. It is suggested that early planning, recruiting, training, connecting with an authorized disaster organization, forming a mental health coalition, organizing administrative and response procedures and personnel, and developing notification and communication procedures should place a state Disaster Response Network in a good position to adapt to changing demands and successfully provide emergency mental health services when needed.
