Abstract
Introduction Research has shown that single-item tools, like the Distress Thermometer (DT), are comparable to longer ones, like the Hospital Anxiety and Depression Scale (HADS). In this study, we tested the validity of the DT in a population of Singapore cancer outpatients, and determined the cut-off scores on the DT for clinically relevant distress and an impaired quality of life (QOL). We also documented the prevalence of anxiety, depression, and QOL impairments in this population. Methods One hundred and five patients (Mdn age = 51-60 years, 64% female, and 71% Chinese) diagnosed with various cancers participated in this study they completed a standard socio-demographic form, the DT and the Problem List, the HADS, and the EuroQOL Quality of Life Scale (EQ-5D). Results Almost a third of patients had clinically significant emotional distress, with 15%-16% having probable levels of anxiety and depression. Almost half (41%-55%) had an impaired QOL compared to Singapore population norms. Receiver operating characteristic curve analyses identified an area under the curve of 0.89 (SE = 0.36, 95% CI [0.82, 0.96], p
