Brief emotional screening in oncology: Specificity and sensitivity of the emotion thermometers in the Portuguese cancer population

Objective. This study aimed to determine the cutoff and the specificity and sensitivity of the Emotion Thermometers (ET) in a Portuguese sample of cancer patients. Method. A total of 147 patients (mean age = 49.2; SD = 12.6) completed the ET, the Brief Symptom Inventory (BSI), and the Subjective Experiences of Illness Suffering Inventory. Data were collected in a cancer support institution and in a major hospital in the North of Portugal. Result. The optimal cutoff for the Anxiety Thermometer was 5v6 (until 5 and 6 or more), which identified 74% of the BSI-anxiety cases and 70% of noncases. The Depression Thermometer cutoff was 4v5 (4 and 5 or more), which identified 85% of BSI-depression cases and 82% of noncases. Cutoff for the Anger Thermometer was 4v5 (4 and 5 or more), which identified 83% of BSI-hostility cases and 73% of noncases; for the Distress Thermometer, the optimal cutoff was 4v5 (4 and 5 or more), which identified 84% of the suffering cases and 73% of noncases. Finally, for the Help Thermometer, it was 3v4 (until 3 and 4 or more), which helped to identify 93% of the suffering cases and 64% of noncases. Significance of results. Results supported the Portuguese version of the ET as an important screening tool for identifying the emotional distress in cancer patients.
