Résumé
The Eating Disorder Examination - Questionnaire Short (EDE-QS) was developed as a 12-item version of the Eating Disorder Examination Questionnaire (EDE-Q) with a 4-point response scale that assesses eating disorder (ED) symptoms over the preceding 7 days. It has demonstrated good psychometric properties at initial testing. The purpose of this brief report is to determine a threshold score that could be used in screening for probable ED cases in community settings. Data collected from Gideon et al. (2016) were re-analyzed. In their study, 559 participants (80.86% female; 9.66% self-reported ED diagnosis) completed the EDE-Q, EDE-QS, SCOFF, and Clinical Impairment Assessment (CIA). Discriminatory power was compared between ED instruments using receiver operating characteristic (ROC) curve analyses. A score of 15 emerged as the threshold that ensured the best trade-off between sensitivity (.83) and specificity (.85), and good positive predictive value (.37) for the EDE-QS, with discriminatory power comparable to other ED instruments. The EDE-QS appears to be an instrument with good discriminatory power that could be used for ED screening purposes.

BACKGROUND
The Eating Disorder Examination - Questionnaire Short (EDE-QS) was developed as a 12-item version of the Eating Disorder Examination Questionnaire (EDE-Q) with a 4-point response scale that assesses eating disorder (ED) symptoms over the preceding 7 days. It has demonstrated good psychometric properties at initial testing. The purpose of this brief report is to determine a threshold score that could be used in screening for probable ED cases in community settings.
METHODS
Data collected from Gideon et al. (2016) were re-analyzed. In their study, 559 participants (80.86% female; 9.66% self-reported ED diagnosis) completed the EDE-Q, EDE-QS, SCOFF, and Clinical Impairment Assessment (CIA). Discriminatory power was compared between ED instruments using receiver operating characteristic (ROC) curve analyses.
RESULTS
A score of 15 emerged as the threshold that ensured the best trade-off between sensitivity (.83) and specificity (.85), and good positive predictive value (.37) for the EDE-QS, with discriminatory power comparable to other ED instruments.
CONCLUSION
The EDE-QS appears to be an instrument with good discriminatory power that could be used for ED screening purposes.
