Development of a Multiplatform Mental Health Mobile Tool

Mobile applications for mental health (MAMH) have shown great potential for delivering digital interventions for the general population. However, most of these apps do not have evidence on how they work. Thus, users may be exposed to products that do not offer any real benefit, or that could harm them. Similarly, the most popular MAMHs use several techniques to deliver their mental health content, but it is still necessary to identify how effective each component is, so that these interventions can be optimized. The aim of this clinical trial is to evaluate how effective the components of evaluation, psychoeducation, and emotional regulation strategies are in a multiplatform MAMH in Chile. 196 adults will have access to different components of the application after consenting to participate in the study. They will be randomly assigned to one of four groups and will use the mobile app for a fixed period. Researchers will compare depressive and anxiety symptoms between the adults in these groups, will either receive: 1. Psychoeducation. 2. Psychoeducation and mindfulness strategies. 3. Psychoeducation and behavioral activation strategies. 4. Psychoeducation and cognitive strategies. All groups will be continuously assessed and monitored. The researchers hypothesize that the psychoeducation combined with any set of self-regulatory strategies will prove more effective than the psychoeducation component alone in decreasing symptomatology.
