Dr. Deacon conducts research on a variety of topics related to the nature and treatment of anxiety, the dissemination of evidence-based therapies, and critical analysis of pseudoscientific mental health practices. He has authored approximately 100 journal articles, book chapters, and books (see here for a current curriculum vitae). His publications have over 9,000 citations and his h-index is 45 (see Google Scholar and ResearchGate for more information), making him one of the most highly cited clinical psychologists in Australia.
In addition to his research on anxiety, Dr. Deacon has published scientific articles on the limited effectiveness of drugs marketed as "antidepressants," the negative psychological effects of believing one's psychological struggles are caused by a "chemical imbalance" in the brain, and the questionable scientific legitimacy and negative societal consequences of the biomedical paradigm that dominates the mental health system. This work earned him recognition in Men's Health magazine in the US and an opportunity to debate the president of the European Psychiatric Association on the effectiveness of "antidepressants" in 2008. He is proud of the special issue of the Behavior Therapist he commissioned on this topic, which he summarised in this concluding essay. Dr. Deacon is passionate about this topic due to its societal importance and impact on the lives of his clients. He believes investigative journalist Robert Whitaker's book Anatomy of an Epidemic: Magic Bullets, Psychiatric Drugs, and the Astonishing Rise of Mental Illness in America, a finalist for the Pulitzer Prize in the US, should be required reading for all healthcare providers and any individual who is currently in or is considering entering the mental health system. He encourages interested readers to check out Whitaker's Mad in America website for in-depth scientific information, news, and other resources on this topic, including the occasional blog post by Dr. Deacon. He also refers readers to The Inner Compass Initiative, an excellent source of accurate information about mental health diagnoses, psychiatric drugs, and related topics.
