Study summary

This research study is designed to investigate the effects of an online computer program, called OxIGen (Oxford Imagery Generation), on thinking style and mood in depression. The OxIGen program will be delivered online over four weeks and with follow-up at one, three and six months. This will inform potential future development of this computerized task into an online intervention to modify negative thinking styles in depression.
