Title: Behavioural Activation-Based Guided Self-Help Treatment Administered Through a Smartphone Application
Brief Summary: The objective is to test the effects of a smartphone-delivered behavioural activation treatment. Also, a moderator analysis of low and high severity of depressive symptoms will be made. We expect the behavioural activation intervention to be superior to the mindfulness intervention for the participants suffering from high severity of depressive symptoms - and the mindfulness intervention to be better or at least as good as the behavioural activation intervention for the participants suffering from low severity of depressive symptoms.
