Objective: Electroconvulsive therapy (ECT) is commonly indicated for refractory psychiatric disorders. However, response comparison across diagnoses is scantly investigated. Here, we aimed to evaluate the relative impact of diagnosis and clinical staging as response predictors in a cross-diagnostic sample., Methods: We investigate, in a retrospective cohort of adult inpatients (N=287) who underwent at least six sessions of ECT, predictors of complete response (a clinical global impression of 1) to ECT. We use adjusted regression models to estimate the impact of clinical diagnosis and staging on complete response and dominance analysis to assess the relative importance of these predictors., Results: Those with a depressive episode as a primary indication for treatment were more likely than all the other groups to have complete improvement, while those with psychosis were the least likely; clinical stage had a significant influence on outcome in all diagnoses. A diagnosis of psychosis stood as the strongest predictor of non-response., Conclusion: An indication of ECT for psychosis (mostly schizophrenia) had a dominant impact in our cohort, indicating a worse chance of response. We also demonstrate that clinical staging can aggregate information on response to electroconvulsive therapy that is independent of clinical diagnosis., Competing Interests: The authors report no conflicts of interest.

Objective:: To distinguish normative fears from problematic fears and phobias., Methods:: We investigated 2,512 children and adolescents from a large community school-based study, the High Risk Study for Psychiatric Disorders. Parent reports of 18 fears and psychiatric diagnosis were investigated. We used two analytical approaches: confirmatory factor analysis (CFA)/item response theory (IRT) and nonparametric receiver operating characteristic (ROC) curve., Results:: According to IRT and ROC analyses, social fears are more likely to indicate problems and phobias than specific fears. Most specific fears were normative when mild; all specific fears indicate problems when pervasive. In addition, the situational fear of toilets and people who look unusual were highly indicative of specific phobia. Among social fears, those not restricted to performance and fear of writing in front of others indicate problems when mild. All social fears indicate problems and are highly indicative of social phobia when pervasive., Conclusion:: These preliminary findings provide guidance for clinicians and researchers to determine the boundaries that separate normative fears from problem indicators in children and adolescents, and indicate a differential severity threshold for specific and social fears.
