What’s new for 2016?

On September 1st 2015, we made all access to PSYCHLOPS free of charge. PSYCHLOPS has always been free for charities, social enterprise organisations and researchers. In legal terms, it will be copyleft (not ‘copyright’) which means that it can be copied freely but not changed without permission from the authors. We are hoping that access and uptake of PSYCHLOPS will be greatly enhanced by making it completely free.

An electronic version of PSYCHLOPS is now available through the CORE IMS website. It is currently being piloted and we are looking for organisations who would like to help with piloting. For further details, click on the Electronic PSYCHLOPS tab above.

The World Health Organization is designing and testing a number of scalable psychological interventions for use in non-specialist services with the aim to reduce the treatment gap for common mental disorders. A modified version of PSYCHLOPS is being used as an outcome measure in WHO Randomised Controlled Trials and as part of the “Problem Management Plus” intervention, which can be found on their website:
