Study summary

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).

Read the detailed description

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.

Ran from Jun 2022 to primary completion in Oct 2023, 16 months.

Of 391 non-industry interventional studies with no phase under Emotional Regulation, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 36. This study's 16 months is below that.

Counting every sponsor, half of 397 studies reached it within 18 months; a quarter within 6 and three quarters within 36.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 7, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
