title: Can the distress thermometer (DT) identify significant psychological distress in long-term cancer survivors? A comparison with the Brief Symptom Inventory-18 (BSI-18).
abstract: BACKGROUND
  As the number of cancer survivors continues to grow, identification of brief, valid psychological screening measures is critical for providing these survivors with appropriate psychosocial care. The distress thermometer (DT) is a one-item distress screening recommended by the National Comprehensive Cancer Network (NCCN) for screening cancer patients during their treatment.
  
  
  METHODS
  In this study, the validity of the DT for identifying psychological distress in cancer survivors was evaluated by comparing results of the DT to the Brief Symptom Inventory-18 (BSI-18) in a sample of 120 survivors of adult onset cancer.
  
  
  RESULTS
  Results indicated that when using the NCCN suggested cutoff score of 5, the DT only identified 10 of the 21 BSI-18 positive cases of psychological distress (sensitivity 47.6%; specificity 90.9%). Using an alternative DT cutoff score of 4, 12 of the 21 BSI-18 positive cases were identified (sensitivity 51.7%; specificity 89.9%).
  
  
  CONCLUSIONS
  The results do not support the validity of the DT in survivors of adult cancers.
