INTRODUCTION The main purpose of this study was to examine the prevalence of symptoms of an emotional and behavioral nature, as well as prosocial type capabilities, measured using the Strengths and Difficulties Questionnaire, in non-clinical adolescents. METHOD The final sample was composed of a total of 508 students, 208 male (40.9%). The age of participants ranged from 11 to 18 years (M=13....

OBJECTIVE Low working memory (WM) is strongly linked with poor academic outcomes. WM capacity increases across childhood but how exposure to school is associated with WM development is not known. We aimed to determine extent to which chronological age and schooling duration are associated with WM at the population level. METHODS In 2012, children in Grade 1 (the second year of formal schoolin...

OBJECTIVES The present study aims to test the factor structure of two sleep questionnaires and their internal consistency in a sample of adolescents and their respective parents and to evaluate the validity and robustness of a three-dimensional model about sleep, addressing nine subcategories related to sleep habits, personal and environmental factors. METHODS Participants were 654 adolescent...

Most working parents face a common dilemma--how to care for their children when they are not in school but the parents are at work. In this article Kathleen Christensen, Barbara Schneider, and Donnell Butler describe the predictable and unpredictable scheduling demands school-age children place on working couples and single working parents.

OBJECTIVE Characterization of academic functioning in children with autism spectrum disorder (ASD), particularly predictors of achievement, may have important implications for intervention. The current study aimed to characterize achievement profiles, confirm associations between academic ability and concurrent intellectual and social skills, and explore preschool predictors of school-age acade...

BACKGROUND Most surveys that assess the iodine status of populations target school-age children, whereas others may target nonpregnant women with the assumption that the iodine status of these groups is representative of other groups in the same population. OBJECTIVE To assess whether the median urinary iodine concentration (UIC) of school-age children or nonpregnant women can be used to accu...

The clinical responses to drug administration can be greatly influenced both by the chronological age of the patient and by the relative maturity of the particular organ system that is being targeted. Human development follows a continuum of time-related events. There are unique therapeutic differences and concerns associated with the treatment of the very young and the elderly patient. Age-dep...

While traditional measures of population ageing are bound to the concept of chronological age, new indicators have been proposed that take into account the dramatic changes that have occurred in later life due to increasing longevity. In this paper, we re-evaluate demographic ageing in Italy using prospective oldage thresholds based on both total remaining life expectancy and remaining life exp...

Understanding the development of white matter microstructure in general population is an imperative precursor to identifying its involvement psychopathology. Previous studies have reported changes associated with age and different developmental patterns between boys girls. Handedness has also been related adults. Motor performance, tightly dependent on overall neuronal myelination, corpus callo...
