We would like to thank the staff at CHIRS and the Centre for Addiction and Mental Health, Brentcliffe Site, who provided training for project personnel, and shared their program materials and expertise freely. A special thanks goes out to Kelly Greer, who generously provided content for the "Staying Healthy" chapter of the Client Workbook and to Megan Cowley, Trish Dekker, Ann Hilliard, Matthias Kaay, David Law and Helen Vilenski who reviewed drafts of workbook chapters. Without their support, this workbook could not have been developed. We would also like to thank John Corrigan for his generous support and consultation.
