RESUMEN
The Strengths and Difficulties Questionnaire [SDQ; (1)] is a multi-informant instrument for screening developmental psychopathology. This study contributes to the validation of the Italian SDQ-Parent version (SDQ-P), analyzing its factorial structure, providing norms and investigating cross-informant agreement (parents-teachers). The SDQ-P and the SDQ-Teacher version (SDQ-T) were completed for 1917 primary and middle school students. Confirmatory factor analyses were performed to compare two factorial structures: the original five-factor model and the structure obtained in a past Italian study (2). The original model showed the best fit. Significant differences by gender and school grade were found; norms were provided separately for males and females attending 1st-2nd, 3rd-5th and 6th-8th grades. Finally, the analysis of parent-teacher agreement showed correlations ranging from small (prosocial behavior) to large (hyperactivity-inattention). This study offers some reflections on the best way to use this instrument in a community sample.

OBJECTIVE: The Brief Visuospatial Memory Test-Revised (BVMT-R) is one of the most widely used tests for the assessment of learning and memory in the visual/spatial domain. The aim of this study was to use multiple regression to derive normative data for the use of BVMT-R in an Italian population. METHOD: We employed a regression-based norms procedure to maximally utilize a relatively small sample while controlling for a variety of demographic factors in addition to age. Additionally, we used these norms to compare the performance of Italian healthy controls with patients diagnosed with multiple sclerosis (MS), thereby providing evidence of the method's validity. RESULTS: A total of 200 healthy volunteers and 70 MS patients participated in this study and completed the BVMT-R according to the published procedures. Regression-based norms were generated for the Italian sample and are presented herein. CONCLUSIONS: Using these norms, the performance of the MS patients was found to be significantly worse than that of the controls.
