摘要
This study assessed the relative screening performance of the Distress Impact Thermometer (DIT) and cutoff levels with the established clinical case threshold of the Hospital Anxiety and Depression Scale (HADS) among a sample of colorectal cancer (CRC) survivors. Fifty-nine CRC survivors completed the DIT, HADS, and provided demographic information at baseline, and 45 of these patients completed the same measures at follow-up, giving a total of 104 participant data. Receiver operating characteristic (ROC) analysis was performed to determine the accuracy of the DIT compared to the HADS, with a cutoff score epsilon 8 on each HADS subscale (depression and anxiety) and epsilon 15 on the HADS total scale used to identify patients with psychological distress. The sample comprised slightly more males (63%) than females, with an average age of 59 years (SD = 9.53) and ranging from 33 to 77 years. The optimum DT cutoff score of epsilon 5 yielded a sensitivity of 60% and specificity of 86.1%; the area under the curve was 0.771 (95% confidence interval [CI] [0.646, 0.896]). For the depression subscale, the DT performed better on specificity than sensitivity, however the opposite was true for the anxiety subscale. The addition of an impact thermometer did not enhance screening performance. The results of this study provide support for a DT score of epsilon 5 for detecting psychological distress among CRC survivors and do not support the addition of an impact thermometer. The use of the DT might underestimate depression but overestimate anxiety.
