Prevention of ANxiety and Depression Over Risk Assessment

Pandora-1 is a behavioral, self-guided and transdiagnostic intervention delivered via an app. It includes predictive risk algorithms, decision support systems (DSS), monitoring and feedback to implement personalized prevention plans (PPP) for anxiety and depression. The intervention has a biopsychosocial approach and offers 4 interactive modules: move more, sleep better, improve relationships and emotional well-being. Participants will receive personalized feedback at baseline, 1, 6 and 12 months, including their levels of depressive and anxiety symptoms over the past two weeks, their predicted risk of developing these disorders in the next year, and related modifiable risk factors (e.g. sedentary lifestyle, insomnia, low social support, poor mental quality of life). Based on this, the app offers suggestions (via DSS) and guides users to relevant content (PPP). Participants follow recommendations of choice, the app tracks these actions and provides feedback at baseline, 1 and 6 months.

Pandora-2 is a psychoeducational self-guided and transdiagnostic intervention delivered via an app. This intervention also has a biopsychosocial orientation and includes a set of psychoeducational brochures for the prevention of anxiety and depression that can be used at any time. These read-only brochures will have contents on the same 4 intervention modules (move more, sleep better, improve relationships and emotional well-being). At baseline, 1 and 6, 12 months participants will also receive basic information about their level of depressive and anxiety symptoms over the past two weeks, their risk probability of depressive and anxiety episodes next year and some of their modifiable risk factors associated with such risk (e.g. sedentary lifestyle, insomnia, low social support and poor mental quality of life). However, in Pandora-2 intervention participants will have lower levels of interactive intervention components as suggestions from the DSS about PPP, monitoring and feedback.
