Longitudinal validation of the Maudsley 3-item visual analogue scale (M3VAS): a new, brief, patient-reported outcome measure of depression.

ABSTRACT:

Background

The Maudsley 3-item visual analogue scale (M3VAS) was developed as a novel and intuitive patient-reported measure for depression, focusing on core symptoms and suicidality.

Aims

To evaluate the longitudinal validity of M3VAS for capturing symptom change over time.

Method

Both M3VAS and the Patient Health Questionnaire (PHQ-9, as reference standard) were administered in an observational study (RHAPSODY, no. NCT04939818) at weeks 0, 2 and 4 to both depressed patients (n = 50) and matched controls (n = 24). We serially tested factor structure, internal consistency and convergence (correlation) over time, assessing responsiveness by both correlation of change in score and effect of time across scales (analysis of variance and effect size).
