DoloTest in General Practice Study: Sensitivity and Specificity Screening for Depression

Background. Coexistence of pain and depression has significant impact on the patient's quality of life and treatment outcome. DoloTest is a pain and HRQoL assessment tool developed to provide shared understanding between the clinician and the patient of the condition by a visual profile. Aim. To find the sensitivity and specificity of DoloTest as a screening tool for depression for patients in primary care. Methods. All patients coming to a primary care clinic were asked to fill in a DoloTest and a Major Depression Inventory. Results. 715 (68.5%) of 1044 patients entered the study. 34.4% came due to pain. 16.1% met depression criteria, and 26.8% of patients coming due to pain met criteria for depression. 65.6% of the men and 54.2% of the women meeting the criteria for depression came due to pain. Depressed patients had statistically significant higher scores on all DoloTest domains. Selecting the cutoff value for the domain “low spirits” to be “65” (0–100) for depression gave a sensitivity of 78% (70–85%) and a specificity of 95% (93–96%) for meeting depression criteria. Conclusion. DoloTest can with a high sensitivity and specificity identify persons meeting criteria for depression and is an easy-to-use screening tool to identify patients with the coexistence of pain and depression.
