OBJECTIVES: We previously reported initial validation of the Emotion Thermometers, a simple 5-domain visual analogue scale inspired by the Distress Thermometer (Psychooncology. 2009 Mar 18; Epub), against depression. Here we aimed to report a definitive validation in a large ethnically diverse sample against Hospital Anxiety and Depression Scale (HADS) defined distress. METHOD: We analysed data collected from Leicester Cancer Centre from 2007-2009 involving approximately 1000 people approached by a research nurse, research physician and two therapeutic radiographers. The researcher applied the HADS and used a HADS-T \gt 14 to signify distress. We collated full data on 660 patient assessments of whom 12.9% had MDD and 14.8 were from ethnic minorities (largely British South Asian of India descent). RESULTS: In the parent sample of 660, sensitivity, specificity and AUC were as follows: DT - 71.9%; 78.4%; 0.814; cut point = 4 AnxT -75.7%; 73.4%; 0.821; cut point = 5 DepT - 77.6%; 82.2%; 0.855; cut point = 3 AngT - 77.5%; 77.6%; 0.823; cut point = 2 HelpT -69.1%; 80.8%; 0.809; cut point = 3. Thus DepT was optimal and has superior sensitivity and specificity to the DT. There was no significant difference by ethnicity. CONCLUSIONS: In this large scale validation of the ET against cancer related distress (on the HADS-T) the DepT may be the optimal thermometer. The optimal cut-point appears to be= >3. The DepT also performs well in those in an ethnic minority namely British South Asian patients.
