Purpose: To describe CAM use in children and adolescents with ASDs in southern Alberta. Methods: A cross-sectional survey of parents. Results: The response rate was 50.3% (176/350). The majority of children were male (83.5%), and diagnosed with classic autism (52.8%). The mean age was 8.9 years. The majority of children (93.8%) had used CAM, most commonly vitamins and minerals (63.1%), mind-body therapies (51.7%), and dietary-nutritional therapies (45.5%). The mean number of types of CAM used was 9.6. The main reason parents used CAM was to improve autistic symptoms in their children. The mean amount spent on CAM was almost $3,000. Most physicians were felt by parents to know about their use of CAM, but the majority of parents felt that they volunteered this information. Roughly one third of both family physicians and pediatricians were perceived to be encouraging of CAM use. Conclusion: The use of CAM in children and adolescents with ASDs is very common, and highlights the need for further research with respect to efficacy, side effects and health policy for these therapies. iii Acknowledgements I would like to acknowledge contributions from the following people and organizations which made this project possible. First, I would like to thank my supervisor, Dr. Marja Verhoef, for her insight, guidance and support throughout this process. I would also like to thank the members of my supervisory committee Dr. Margaret Clarke and Dr. Bonnie Kaplan whose interest, expertise and encouragement were invaluable. I am grateful to Matthew Hicks who provided advice, support, and encouragement throughout this project. This research would not have been possible without the support of a number of outstanding organizations who support children and adolescents with autistic spectrum disorders and their families. These organizations include Autism Calgary Association, Renfrew Educational Services, Janus Academy, Leaps & Bounds, Kolaczek Consulting Services, the Society for Treatment of Autism, and Providence Children’s Centre. Finally, I would like to thank my family - Marilyn, Katherine, and Evan - whose ongoing support and understanding helped me persevere through this endeavour. iv Dedication To Marilyn, Katherine and
