Nonnormality of univariate data has been extensively examined previously (Blanca et al., 2013; Micceri, 1989). However, less is known of the potential nonnormality of multivariate data although multivariate analysis is commonly used in psychological and educational research. Using univariate and multivariate skewness and kurtosis as measures of…

The present study investigated the development of fraction comparison strategies through a longitudinal analysis of children's responses to a fraction comparison task in 4th through 6th grades (N = 394). Participants were asked to choose the larger value for 24 fraction pairs blocked by fraction type. Latent class analysis of performance over item…

Youth with disabilities have much lower participation rates in postsecondary education compared with youth without disabilities. There is a need to understand ecological factors that influence their differential participation. This research examined the impact of parental receipt of welfare on postsecondary enrollment among youth with…

This study explores the longitudinal effect of adolescent volunteering behaviour on young adult volunteering and the completion of secondary school. Utilising data from the Australian sample of the International Youth Development Study, frequency of volunteering in Grade 9 (mean age = 15 years) and in young adulthood (mean age = 21 years), and…

In this study, we explored the influence of kindergarten children's perspectives of school on their literacy and self-regulation outcomes. Children's early perspectives were captured in a three-question, finger-puppet interview. Responses to the interview questions were coded thematically as being academic and/or social in nature, and were…

Objective: Colleges have increased postsecondary educational access for youth, including individuals with disabilities, but completion rates remain low. This study tests the hypothesis that health conditions that reduce social integration predict lower educational attainment among college students. Method: The sample from the nationally…

Many methods exist for imputing missing data but fewer methods have been proposed to test the missing data mechanism. Little (1988) introduced a multivariate chi-square test for the missing completely at random data mechanism (MCAR) that compares observed means for each pattern with expectation-maximization (EM) estimated means. As an alternative,…

This study examines the relationship between self-regulated learning (SRL), parent education, and the need to enroll in postsecondary remedial education courses, using first year college student data from the National Center for Education Statistics (NCES) Education Longitudinal Study of 2002 (ELS: 2002). This observational study was conducted…

Purpose: The purpose of this study was to examine whether childhood misfortune reduces the likelihood of being disease free in adulthood. Design and Methods: This article used a sample of 3,000+ American adults, aged 25-74, who were first interviewed in 1995 and reinterviewed in 2005. Logistic regression was used to estimate the odds of avoiding…

Background: Hospitalisations for ambulatory care-sensitive (ACS) conditions are used as an indicator of access to, and the quality of, primary care. The objective was to identify factors associated with hospitalisations for ACS conditions among adults with an intellectual disability (ID) in the context of a publicly insured healthcare system.…

This study investigated the prevalence and stability of latent classes at risk for reading disabilities (RD) in elementary-aged children whose first language is Spanish. To this end, children (N = 489) in Grades 1, 2, and 3 at Wave 1 were administered a battery of reading, vocabulary, and cognitive measures (short-term memory [STM], working memory…

National Longitudinal Survey of Youth and census data are used to examine the effect of both individual- and contextual-level determinants on Latinas' transition to first marriage (n = 745). Hypotheses derived from 4 leading theories of marriage timing are evaluated. Discrete-time event-history models that control for clustering within Labor…

Four Australian cohorts (born in 1961, 1965, 1970 and 1975) were studied between 1980-2000. The life transitions study focused on these three traditional markers of adulthood: (1) moving out of the parental home; (2) establishing an intimate relationship; and (3) buying a home. Incidence of these transitions was analyzed in terms of their…
