RESUMO
Los trastornos ansiosos en la población chilena infantojuvenil son de alta prevalencia y frecuentemente subdiagnosticados. Han existido variados intentos para crear instrumentos que ayuden a su tamizaje, dentro de estos el SCARED es uno de los más utilizados. Para la población hispanoamericana se adaptó este autoreporte de niños y adolescente (AANA) con características psicométricas adecuadas. El objetivo del presente trabajo es analizar la capacidad para discriminar entre Trastorno ansioso y sus distintas dimensiones (pánico/somático, ansiedad de separación, ansiedad generalizada, fobia social y fobia escolar) del AANA en población infantojuvenil chilena no consultante. Los resultados obtenidos mostraron que el instrumento estudiado es capaz de determinar un único constructo (ansiedad) y que los distintos ítems logran determinar las 5 dimensiones encontradas en el estudio original. De acuerdo a los resultados es posible concluir que el AANA es un instrumento adecuado para pesquisar trastornos ansiosos en la población infantojuvenil chilena estudiada.

Anxiety disorders in chilean children and adolescents are highly prevalent and often underdiagnosed. Various attempts have been made to design tools which contribute in the screening of these conditions, among these the SCARED is one of the most popular ones. An adaptation of this instrument has been developed for hispanic population, the AANA (anxiety self-report for children and adolescents), which has proven adequate psychometric characteristics. The aim of this article is to analyzethe AANA's discriminant capacity for anxiety disorders and its various dimensions (panic / somatic, separation anxiety, generalized anxiety, social phobia and school phobia) in Chilean non consulting children and adolescents. Our results showed that this instrument was able to determine a single construct (anxiety) and its items succeeded in identifying the 5 dimensions found in the original study. According to these results, we can conclude that the AANA is a suitable instrument for anxiety disorders screening in the chilean child and adolescent population studied. Key words: Anxiety disorders, self-reporting, SCARED, exploratory factor analisys,children and adolescents.
RESUMO
OBJECTIVE: To examine gastric function, as well as the presence of somatic complaints, anxiety symptoms, and functional gastrointestinal disorders (FGIDs), in adolescents with anorexia nervosa (AN) before and after nutritional rehabilitation. STUDY DESIGN: Sixteen females with AN and 22 healthy controls with similar demographic profiles were included. Gastric emptying (measured as residual gastric volume) and gastric accommodation (measured as postprandial antral diameter) were assessed with abdominal ultrasonography. Participants completed the Children's Somatization Inventory (CSI), the Screen for Child Anxiety-Related Emotional Disorders, and the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III version. All testing was repeated 3-4 months later. RESULTS: Body mass index in the AN group improved over time (P = .012). Fasting gastric parameters were similar in the 2 groups. Maximum postprandial antral diameter was significantly greater in controls compared with the AN group (P = .008). Only adolescents with AN demonstrated a significant increase in maximum postprandial diameter at repeat testing (P = .009). There was no difference in residual gastric volume between the 2 groups. Initial CSI scores were higher in adolescents with AN (P < .0001), including higher scores for nausea and abdominal pain. CSI scores were significantly lower in adolescents with AN (P = .035). Initial scores on the Screen for Child Anxiety-Related Emotional Disorders were significantly higher in adolescents with AN (P = .0005), but did not change over time. Adolescents with AN met significantly more criteria for FGIDs (P = .003). CONCLUSION: Adolescents with AN have impaired gastric accommodation that improves after nutritional rehabilitation, have significantly more somatic complaints, and meet more criteria for anxiety disorders and FGIDs. After nutritional rehabilitation, somatization improves and FGIDs become less common, but symptoms of anxiety persist.
