On the first 1-2 days of each of in total 5 weeks, participants read a brief lesson introducing that week’s skill(s). For the rest of the week, they received a ‘home practice’ assignment consisting of one or more simple practices, such as noticing positive events or tracking progress toward an attainable goal. Participants were asked to visit the web-site everyday to record their home practice and complete the daily emotion reporting questionnaire. Intervention content focussed on positive events, mindfulness, reappraisal, strengths and goals, acts of kindness.
