The project will be carried out in three complementary phases, which will include a feasibility study
(first phase), a qualitative study (second phase) and a randomized controlled trial (third phase) comparing the
smartphone application (SIMPLe) on top of treatment as usual with treatment as usual alone. During the first phase,
feasibility and satisfaction will be assessed with the application usage log data and with an electronic survey. Focus
groups will be conducted and technical improvements will be incorporated at the second phase. Finally, at the third
phase, survival analysis with multivariate data analysis will be performed and relationships between socio-demographic,
clinical variables and assessments scores with relapses in each group will be explored.
