#1. INCORPORATING SENSIBILITY AND SPECIFICITY IN STATISTICAL INFERENCE IN EPIDEMIOLOGY OF DEPRESSION
Gabriel González-Medina
Confidence intervals are calculated no considering measurement error, for this reason, statistical inference is only made considering sample error. Particularly, estimation of prevalence is very important in epidemiology because the government needs to consider a likely population to provide enough treatment, however, these estimations are conservative because of standardized questionnaires have a greater probability to no identify true cases in comparison to identify false cases. In this sense, sensibility and specificity generate asymmetry in measurement error, besides asymmetry in confidence interval.

#2. Dissociable hormonal responses to symptoms and stress in anorexia and bulimia nervosa
Margaret Westwater, Flavia Mancini, Jane Shapleske, Jaco Serfontein, Monique Ernst, Hisham Ziauddeen, Paul Fletcher
Background: Anorexia nervosa (AN) and bulimia nervosa (BN) are complex psychiatric conditions, in which both psychological and metabolic factors have been implicated. Critically, the experience of stress can precipitate loss-of-control eating in both conditions, suggesting an interplay between mental state and metabolic signaling. However, associations between psychological states, symptoms and metabolic processes in AN and BN have not been examined. Methods: Eighty-five women (n=22 AN binge/purge subtype, n=33 BN, n=30 controls) underwent remote salivary cortisol sampling and a two-day, inpatient study session to examine the effect of stress on cortisol, gut hormones (acyl-ghrelin, PYY, GLP-1) and food consumption. Participants were randomized to either an acute stress induction or control task on each day, and plasma hormones were serially measured before a naturalistic, ad libitum meal. Results: Cortisol awakening response (CAR) was augmented in AN but not BN relative to controls, with body mass index explaining the most...
