Screening young adult cancer survivors for distress with the Distress Thermometer: Comparisons with a Structured Clinical diagnostic interview
Menée aux Etats-Unis auprès de 247 patients ayant survécu à un cancer et âgés de 18 à 40 ans, cette étude compare l'efficacité de deux outils, un questionnaire et un entretien structuré, pour détecter et évaluer leur détresse psychologique
BACKGROUND The validity of the Distress Thermometer (DT) as a screen for psychological distress in young adult cancer survivors was assessed by comparing it with the results of a psychiatric diagnostic interview, the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) (SCID), to evaluate the accuracy of the DT and identify optimal cutoff scores for this population. METHODS A total of 247 survivors aged 18 to 40 years completed the DT and SCID. Based on the SCID, participants were classified as having: 1) ≥ 1 SCID diagnoses; 2) significant symptoms, but no SCID diagnosis; or 3) no significant SCID symptoms. Receiver operating characteristic analyses determined the sensitivity and specificity of all possible DT cutoff scores for detecting survivors with a SCID diagnosis, and subsequently for survivors with significant SCID symptoms or a SCID diagnosis. RESULTS The recommended DT cutoff score of ≥5 failed to identify 31.81% of survivors with a SCID diagnosis (sensitivity of 68.18% and specificity of 78.33%), and 32.81% of survivors with either significant SCID symptoms or a SCID diagnosis. No alternative DT cutoff score met the criteria for acceptable sensitivity (≥85%) and specificity (≥75%). CONCLUSIONS The DT does not reliably identify young adult cancer survivors with psychiatric problems identified by a “gold standard” structured psychiatric interview. Therefore, the DT should not be used as a stand-alone psychological screen in this population. Cancer 2015. © 2015 American Cancer Society.
