This article is aimed at evaluating the possibility that Set I of the Advanced Progressive Matrices (APM-Set I) can be employed to assess fluid ability in a short time frame. The APM-Set I was administered to a sample of 1,389 primary and secondary school students. Confirmatory factor analysis attested to the unidimensionality of the scale. Item response theory analyses were applied to investigate the increasing level of item difficulty, test information function, and differential item functioning across gender and age. Additionally, validity measures are reported. Results provide evidence that the APM-Set I can be used as a reliable and valid short form of the Raven's Progressive Matrices in the assessment of fluid ability.

Objectives: The Ages & Stages Questionnaires Third Version (ASQ-3) identifies the risk of developmental delay in children aged 1 to 66 months. The aim of this study was to determine a reliable and valid instrument for the Italian population to enable the screening of children’s development. Methods: Data from 2278 Italian children (age range: 1–66 months) were used to evaluate item discrimination power using the corrected item-total correlation. Internal consistency was analyzed by Cronbach’s alpha scores and a Confirmative Factor Analysis was conducted to test the factor structure of the test. Data were also collected to examine the ASQ-3 test-retest reliability and concurrent validity, which was investigated using the Griffiths Scales of Child Development, Third Edition, the Peabody Developmental Motor Scale, Second Edition, and the Developmental Profile, Third Edition tools. In order to evaluate discriminant validity, differences between typical development children and several clinical groups have been performed. Finally, two different cut-off scores have been proposed. Results: The results showed that the questionnaires are composed of high-quality items; the original factor structure has been confirmed and strong Pearson product-moment correlation coefficients between the overall and the total for each domain (ranging from 0.73 to 0.88). The Italian version of the ASQ-3 had adequate internal consistency and a strong agreement between observations with two weeks’ intervals. Moreover, the test showed a high discriminant validity due to the possibility of fully discriminating between typical development children and several clinical groups. Finally, two different cut-off scores have been identified using ROC curves in order to have a screening and a diagnostic cut-off value. Conclusion: This study evaluated the psychometric properties of the Italian adaptation of ASQ-3 questionnaires. We demonstrated the validity of the ASQ-3 and determined new cut-off scores for Italian children. Early identification and accurate assessment are important starting points to better understand and anticipate the needs of children and their link to services.

In this study, two alternative theoretical models were compared, in order to analyze which of them best explains primary school children's text comprehension skills. The first one was based on the distinction between two types of answers requested by the comprehension test: local or global. The second model involved texts' input modality: written or oral. For this purpose, a new instrument that assesses listening and reading comprehension skills (ALCE battery; Bonifacci et al., 2014) was administered to a large sample of 1,658 Italian primary school students. The two models were tested separately for the five grades (first to fifth grade). Furthermore, a third model, that included both the types of answers and the texts' input modality, was considered. Results of confirmatory factor analyses suggested that all models are adequate, but the second one (reading vs. listening) provided a better fit. The major role of the distinction between input modalities is discussed in relation to individual differences and developmental trajectories in text comprehension. Theoretical and clinical implications are discussed.

This study analyzes the psychometric characteristics of an Italian test of executive function (EF) tests assessing inhibition, set-shifting and working memory (core executive functions) for preschool children. BAFE is based on a concept accredited by the majority of EF research: a representation articulated in a profile of neuropsychological processes relatively independent. The main goal of this study was to assess the multiple EF components of BAFE Test in 3 to 6-year-old children and its sensivity, validity and reliability to age differences. In order to evaluate the convergent validity of the BAFE test, a correlation between different tests assessing similar neuropsychological constructs were performed. The framework of the relationships between the tests for children shows associations and dissociations compatible with the theoretical hypotheses on executive functions. BAFE test offers additional measures for clinical evaluations for preschoolers. It could introduce new clinical practice that add to clinical observations or questionnaires a rigorous measurement tools with good psychometric properties.
