✦ Synopsis

A Radiation Therapy Oncology Group Study I n their recent article, Coyne et al. 1 vastly overstated the quality of their study and the meaning of their findings.

Poor Measurement

They used only 4 items from an Emotional Well-Being subscale, which hardly constitutes a reliable assessment of depression or anything else, and produces little variance. Coyne et al stated that the subscale contains 5 items, 1 but it actually contains 6. 2 Furthermore, the questions utilized do not assess how the person handles their distress (eg, by avoidance, suppression of emotion, substance abuse, etc.). 3 Moreover, although the patients in the study had squamous cell carcinomas, the validation was performed on a sample of 240 breast cancer patients. Reliability and validity are population specific.
