Study type
Description of intervention(s) / exposure
The positive psychology intervention will involve the serial completion of activities (known as positive activities) over a period of eight weeks; one activity per week. The positive activities to be performed are: Week 1 - "What Went Well"?; Week 2: Gratitude Letter; Week 3 - Acts of Kindness; Week 4 - Best Possible Future Self; Week 5 - Nurturing Social Relationships; Week 6 - Get Active; Week 7- Committing to Your Goals; and Week 8 - Increasing 'Flow' Experiences. The activities take approximately 20-30 minutes to complete and only needed to be completed once during the week. Adherence will be monitored through bi-weekly phone calls to the participant to check activity completion. Participants will also be required to keep a diary recording activity completion. This will be collected by the study investigators at the end of the intervention phase. Activities will be administered using a handbook (hard copy or electronic PDF).
