“…We used self-reported information obtained via the validated SCOFF questionnaire. Whereas it is not a diagnostic tool, it has been strongly recommended for ED screening given its excellent psychometric properties20 and its capacity to provide a realistic approximation of actual ED point prevalence. It is one of several instruments used in the assessment of likely ED, in addition to the DSM criteria.…”

“…That instrument had been validated for use with French-speaking adults 19. A diagnostic threshold is fixed at two positive responses, with a sensitivity of 0.88 and a specificity of 0.93 using interviews as diagnostic reference 20. Data obtained with SCOFF are regarded as reflecting likely ED realistically approximating actual ED point prevalence 20.…”

BackgroundOn the population level, the association of age and other sociodemographic factors with eating disorders (ED) is unclear.MethodsWe used cross-sectional data from the French general population-based NutriNet-Santé e-cohort (n=49 603 adults; 76.3% women; mean age=50.4±14.6 years). ED were evaluated in 2014 with the 5-item SCOFF screening questionnaire and the Expali algorithmic tool. Likely cases of restrictive, bulimic, hyperphagic and other ED were the dependent variables. Age, marital status, education, occupation, physical activity and smoking were the independent variables. Associations were estimated via gender-stratified multivariable polytomous logistic regression.ResultsAmong women, age displayed inverse linear associations with both restrictive and bulimic ED, underscoring 18–25 years as the most vulnerable period (adjusted OR=3.37, 95% CI: 2.24 to 5.08 for restrictive ED; adjusted OR=2.98, 95% CI: 2.37 to 3.74 for bulimic ED, respectively). A similar association was observed in men regarding bulimic ED. In women, age was not associated with hyperphagic ED for which living alone, low education, low physical activity, being a homemaker/disabled/unemployed/retired, a manual worker or a former/current smoker had increased importance. In men, 18–39 years emerged as the least vulnerable period regarding hyperphagic ED (adjusted OR=0.74, 95% CI: 0.56 to 0.99). Across gender, having postsecondary education had significant inverse associations with all except restrictive ED, whereas being a student had a significant positive association with restrictive ED.ConclusionsThe findings support gender-specific associations of age with four ED subtypes and could inform future prevention initiatives targeting specific ED among specific age groups.Trial registration numberNCT03335644; Pre-results.

“…The procedure outlined in this paper can be applied to refine meta-analytic estimates of the accuracy of tests employed for binary classifications. Such meta-analyses integrate primary studies that assess the accuracy of binary classifications performed on a specific test (e.g., Botella et al, 2013). If the primary studies included in a meta-analysis have been carried out using an IR, the combined estimate of the accuracy will be incorrect, unless the imperfection of the reference is detected and assessed.…”

Studies that evaluate the accuracy of binary classification tools are needed. Such studies provide 2 × 2 cross-classifications of test outcomes and the categories according to an unquestionable reference (or gold standard). However, sometimes a suboptimal reliability reference is employed. Several methods have been proposed to deal with studies where the observations are cross-classified with an imperfect reference. These methods require that the status of the reference, as a gold standard or as an imperfect reference, is known. In this paper a procedure for determining whether it is appropriate to maintain the assumption that the reference is a gold standard or an imperfect reference, is proposed. This procedure fits two nested multinomial tree models, and assesses and compares their absolute and incremental fit. Its implementation requires the availability of the results of several independent studies. These should be carried out using similar designs to provide frequencies of cross-classification between a test and the reference under investigation. The procedure is applied in two examples with real data.
