Is this trial a fit for you?

Likely a good fit

Adults (≥18) with mild to severe unipolar depression who are outpatients, French-speaking, able and willing to use a smartphone or computer, and who consent to eight weeks of monitoring.

Probably not a fit

Patients who are hospitalized, have bipolar disorder, recent serious suicidal behavior, are on very high doses of benzodiazepines or antipsychotics, lack the necessary technology or French language fluency, or otherwise meet exclusion criteria are unlikely to benefit from participating.

What this trial studies

This prospective, multicenter, single-arm observational study will enroll adult outpatients with unipolar depression who install the EmoDTx application on a smartphone or computer and use it during an eight-week follow-up. EmoDTx passively analyzes facial expressions to generate mood scores that will be compared with standard clinician- and self-rated depression scales (MADRS, PHQ-9, BDI-II, HAMD-17, QIDS-SR16). Participants can activate or deactivate the software at any time and will attend scheduled visits for concurrent questionnaire assessments. The study will also collect patient feedback on passive monitoring and whether app-generated feedback helps in their care.

Why it matters

Potential benefit: If successful, EmoDTx could provide continuous, low-burden mood tracking that helps clinicians detect changes sooner and personalize care.

How similar studies have gone: Previous digital phenotyping and facial-expression analysis studies have shown promising but mixed results, so this approach is partially supported but still requires validation against clinical scales.
