Brief summary

This randomized controlled trial will evaluate the Norwegian adaptation of the Big Five intervention (Things You Do; TYD) for individuals with self-reported anxiety and/or depressive symptoms. The study will compare the Big Five intervention with a Gratitude intervention and a waitlist control. A total of 410 participants will be recruited online and randomized to one of three groups. Intervention groups will receive a brief module and daily SMS reminders (Monday-Friday for four weeks) encouraging engagement in either the five daily actions or gratitude practices. The primary aim is to replicate findings from the Australian trial by comparing TYD to a waitlist control. A secondary aim is to examine whether TYD yields better outcomes than the active Gratitude control. This study will provide evidence on the effectiveness and cross-cultural applicability of a low-cost, scalable intervention for improving mental health. Data from the study will also be used to evaluate the psychometric properties of the Norwegian translation of the Things You Do-15 instrument (TYD-15).

Detailed description

Researchers in Australia have identified five central daily actions that are associated with mental health and may account for 37 % of the variance in anxiety and depressive symptoms: Healthy thinking, Meaningful Activities, Goals and Plans, Healthy Habits, and Social Connections. Conducting these actions more than three to four times a week may improve symptoms of anxiety and depression. Aim: The current study aims to replicate the findings from the Australian developers by adapting the intervention to a Norwegian context in a randomized controlled trial.
