There is widespread consensus that psychological factors play a pivotal role in the development and maintenance of chronic pain, pain-related distress and disability. Regrettably, there is a pressing need to ensure trustworthiness of this evidence base. We have identified key challenges and outlined recommendations for advancing research in the domain of pain psychology, amongst which problems related to vague concept definitions and inadequate self-report questionnaires. This project addresses these challenges using state of the art procedures and recommendations, and provides an in depth content-based evaluation of self-report measures and their items. Knowledge will be systematically stored and made available in open repositories and in a purpose-built ontology for (re)use.
