Covariates have been used in mixture IRT models to help explain why examinees are classed into different latent classes. Previous research has considered manifest variables as covariates in a mixture Rasch analysis for prediction of group membership. Latent covariates, however, are more likely to have higher correlations with the latent class…

Objective: To examine the longitudinal trajectory of daytime dysfunction (DD) and its relationship with fatigue by depression status in university students. Participants: 243 students completed online surveys from September-December 2016. Methods: Surveys were conducted at three time points over a semester period: the beginning of the semester,…

Recent evidence demonstrates that disparities by race/ethnicity and socioeconomic status in science achievement are present in the earliest grades of school. Preschool represents one potential policy solution; however, little research has explored the relationship between preschool attendance and science outcomes. This study examines whether…

The objective of the present study was to investigate prosocial behaviour, aggression types and moral and social rule knowledge perceptions of 4-5 year old preschool children. The study sample included 310 children (154 female and 156 male), who were attending a pre-school education institution during the 2017-2018 academic year. A personal…

The goals of this study were to analyze the growth and stability of vocabulary, mean length of the three longest utterances (MLLUw), and sentence complexity in European Portuguese-speaking children aged 1;4-2;6, to explore differences in growth as a function of personal and family-related variables, and to investigate the inter-relationships among…
