A mobile-based randomized controlled trial on the feasibility and effectiveness of screening for major depressive disorder: study protocol

A Mobile-Based Study on Screening for Major Depressive Disorder

Overview

This study aims to explore how effective and practical it is to screen for Major Depressive Disorder (MDD) using mobile technology. Early detection and treatment of MDD can significantly reduce its impact on society.

Study Design

The research will involve a randomized controlled trial (RCT) with three groups in Rotterdam, Netherlands:

  • One-Test Group: Participants will be screened every 4 weeks for 12 months. If they show moderate to severe symptoms (PHQ-9 score > 10) in one test, they will be referred for further diagnosis and treatment.
  • Multiple-Test Group: Participants will only be referred after three consecutive positive test scores.
  • Control Group: This group will not receive mobile screening for MDD.

A total of 1,786 participants will be included, with 446 in the one-test group, 447 in the multiple-test group, and 893 in the control group.

Outcomes

The main goal is to assess the quality of life (QoL) of participants after 12 months. Secondary goals include:

  • Quality of life after 24 months
  • Evaluation of MDD symptoms
  • Engagement with the screening intervention
  • Understanding mental health differences across various demographics

Long-term results will help analyze the benefits, costs, and potential harms of MDD screening.

Importance of the Study

The findings from this research could guide mental health policies and support the adoption of mobile screening for MDD in the Netherlands and beyond.
