The present study examined the predictive effects of intellectual ability, self-concept, goal orientations, learning strategies, popularity and parent involvement on academic achievement. Hierarchical regression analysis and path analysis were performed among a sample of 1398 high school students (mean age = 12.5; SD =.67) from eight education centers from the province of Alicante (Spain). Cognitive and non-cognitive variables were measured using validated questionnaires, whereas academic achievement was assessed using end-of-term grades obtained by students in nine subjects. The results revealed significant predictive effects of all of the variables. The model proposed had a satisfactory fit, and all of the hypothesized relationships were significant. These findings support the importance of including non-cognitive variables along with cognitive variables when predicting a model of academic achievement.

Using various identification methods, differences between underachieving and non-underachieving gifted students in personal, familial, social, and school variables were analyzed in a sample of 164 gifted students with IQs of 120 or higher; the sample was drawn from a larger sample of 1,400 compulsory secondary education students. Three procedures for identifying underachieving students were used: the standardized difference method, the regression method, and the Rasch method. The different profiles of underachieving and non-underachieving students in the personal, familial, social, and school variables were compared using MANOVA and ANOVA tests. Results revealed that underachieving gifted students scored significantly lower in learning strategies, goal orientations, self-concept, attitudes toward teachers, and perceived parent involvement in school variables. These results have clear educational implications as a result of identifying differences in non-cognitive factors.

In recent years there has been a significant rise in the number of psychometric studies, together with crucial statistical advances for validity and reliability measures. Given the importance of providing accurate procedures both in methodology and score interpretation of tests and/or measurement scales, the editors-in-chief of the journal Annals of Psychology have drafted this guide to address the most relevant issues in the field of applied psychometry. To this end, the present manuscript analyses the main topics under the Classical Test Theory framework (e.g., exploratory/confirmatory factor analysis; reliability, validity, bias, etc.) aiming to synthesize and clarify the best practical applications, and improve publication standards. Recientemente se ha incrementado significativamente el número de estudios psicométricos junto a avances estadísticos cruciales para evaluar la fiabilidad y validez de los tests. Dada la importancia de proporcionar procedimientos más exactos tanto en la metodología como en la interpretación de las puntuaciones, los editores de la revista Anales de Psicología proponen esta guía para abordar los tópicos más relevantes en el campo de la psicometría aplicada. Con esta finalidad, el presente manuscrito analiza los tópicos principales de la Teoría Clásica de Tests (e.g., análisis factorial exploratorio/confirmatorio, fiabilidad, validez, sesgo, etc.) con vistas a sintetizar y clarificar las aplicaciones prácticas, y mejorar los estándares de publicación de estos trabajos.

There is a need for a measure that can be used across countries and cultures to advance cross-cultural research about internalizing mental health symptoms in children and adolescents. The Revised Children's Anxiety and Depression Scale (RCADS) is a potential candidate, but no study has examined whether its scales are measured similarly in youth populations from different countries. In this study, we use confirmatory factor analysis (CFA) and multi-group CFA to examine the cross-cultural properties of a short and free to use 30-item version of RCADS that assesses social, generalized, panic, and separation anxiety alongside depression and obsessive-compulsive symptoms. We tested the factor structure of RCADS in children and adolescents from Chile, Spain, and Sweden, recruited using different research designs (i.e., school-based studies and an anonymous web survey), and whether the factor structure showed measurement invariance across the three countries. The proposed factor structure of RCADS showed good model/data fit in all three countries and was superior to a unidimensional model in which correlations among scale items were explained by a single broad internalizing factor. Each RCADS subscale showed adequate to excellent internal consistency in all three countries and multi-group CFA supported scalar invariance across the three countries. No clinical sample was included. This study provides an important first step in supporting the use of RCADS in cross-cultural research on depression, anxiety and obsessive-compulsive symptoms in children and adolescents, but more work on validity aspects of the scale across cultures is needed.
