Clinical and health psychology...

...materials can be found on the wide-ranging (and free!) Trip Database, which someone has recommended to me. It seems to be aimed primarily at clinicians and clinical professionals (namely medical practitioners), but the overlap into health psychology-related topics is sufficient to make it a potentially useful resource. It focuses on 'evidence', which includes systematic reviews, guidelines (split by country), Q&As and even e-Textbooks. Give it a go and let me know what you think!
