Objective: The six-item Hamilton Depression Rating Scale (HAMD6) is a clinician rated measure which lacks a self-report companion. We explored whether a six-item client rated visual analogue scale (VAS6) based on the HAMD6, was a consistent and valid measure of depression and useful for clinical practice. Method: Participants were N = 117 participants, 88 (75%) female, with major depressive disorder (MDD) who received transcranial magnetic stimulation (TMS). Pre- and post-treatment a trained clinician completed the HAMD6 and Clinical Global Impression Scale for Severity (CGI-S), and patients the self-reported VAS6.
Results: internal consistency using Cronbach's alpha was 0.87. VAS6- HAMD6/GGI-S spearman correlations were moderate-strong for four items (depressed mood; work/activities; feelings of guilt; anxiety) and the total score and weak for two items (somatic symptoms, retardation).
Conclusions: The self-reported VAS6 was a valid measure of core aspects of depression measured by the HAMD6. It is cost effective (takes relatively little clinician time) and is a useful companion to the clinician reported HAMD6.
