Spanish normative data of the Strengths and Difficulties Questionnaire in a community-based sample of adolescents

2022

Background/Objective: The Strengths and Difficulties Questionnaire self-report (SDQ-S) has been extensively used to assess mental health problems among children and adolescents. However, previous research has identified substantial age and country variation on its psychometric properties. The aim of this study was three-fold: i) to evaluate internal structure and measurement invariance of the Spanish version of the SDQ; ii) to analyze age and gender-specific effects on the SDQ subscales; and iii) to provide Spanish normative data for the entire age range of adolescence. Method: Data were derived from two representative samples of adolescents aged 14 to 19 years old, selected by stratified r…

UKIRT Observations of the Impact and Consequences of Comet Shoemaker–Levy 9 on Jupiter☆

1997

The observation of Comet Shoemaker-Levy 9's collision with Jupiter in July of 1994 by the United Kingdom Infrared Telescope (UKIRT) produced spectroscopic data of high quality. Analysis of the data for Impact C has produced the first temperature curve that covers such an event, from the first visibility of the plume above the limb through to the settling down of the ejected gas onto the upper jovian atmosphere. Temperatures derived from methane emission show that 5 min after impact, a plume some 6500 km across was heated to similar to 1400 K. At its maximum spatial extent similar to 12 min after impact, a region of Jupiter's atmosphere similar to 45,000 km west from the impact site of the m…
