The prospects for people with mental health problems have greatly improved. We now have effective psychological therapies for a wide range of mental health conditions. However, in most countries only a few members of the public benefit from these advances. This talk shows how effective psychological therapies can be developed from sound psychopathology research and how combining psychology with economics and politics can make them widely available to the public. The discussion of dissemination will particularly focus on two initiatives. The first is the English Improving Access to Psychological Therapies (IAPT) programme which currently treats over 600,000 people with depression and/or anxiety disorders each year, obtains clinical outcome data on 98% of these individuals and places this information in the public domain. Around 50% of patients treated in IAPT services recover and two-thirds show worthwhile benefits. The second initiative is the rapidly expanding field of digitally assisted therapy which is allowing therapists to treat more patients, in a way that is often also very convenience for the patients themselves.
