Investigating the effectiveness of two mobile psychological interventions and the mechanisms of change involved in reducing the symptoms of depression, anxiety and stress, on an adult population with a mild to moderate level of symptoms (sub-clinical).
The research design will be a 3-arm controlled clinical trial, with 4 waves of data collection. Once selected using a symptomatic screening questionnaire, participants will be randomly assigned to one of three conditions: 2 experimental conditions (PsyPills and OCAT) and an active control group (shamOCAT).
Measurements will be collected before allocation (baseline), during the intervention (through a momentary ecological assessment paradigm), at the end (post) and at an interval of one month after the intervention (follow-up). Among the constructs evaluated are symptomatic level, affectivity, cognitive processes, emotional regulation and attentional bias. All measurement steps will be collected online.
The interventions consist of an attentional training (Online-Contingent Attention Training, OCAT) which seeks to facilitate the disengagement from the negative content and the engagement on the positive of some personally relevant information by providing instructions and feedback on performance; and prescribing personalized rational thinking strategies to change the intensity of dysfunctional emotionality (PsyPills). The active control group consists of a "fake" version of OCAT (shamOCAT), by offering the same attentional training, without training and feedback on performance. All interventions are delivered in the form of smartphone applications.

Participants in all categories will be announced that they have received a mobile intervention aimed at distress reduction, without knowing the the rationale and specifics of each intervention. Outcomes will be assessed only by online questionnaires, so no assessor is involved.
