We provide conceptual introductions to missingness mechanisms--missing completely at random, missing at random, and missing not at random--and state-of-the-art methods of handling missing data--full-information maximum likelihood and multiple imputation--followed by a discussion of planned missing designs: Multiform questionnaire protocols, 2-method(More)
Parent and child mealtime behaviors associated with consumption of unfamiliar foods by children with ASD were examined. Families of 38 children aged 2 through 8 years old and diagnosed with ASD videotaped a typical home mealtime during which parents presented the child with an unfamiliar food and mealtime behaviors were subsequently coded through an(More)
The assumption of equivalence between measurement-model configurations across groups is typically investigated by evaluating overall fit of the same model simultaneously to multiple samples. However, the null hypothesis (H0) of configural invariance is distinct from the H0 of overall model fit. Permutation tests of configural invariance yield nominal Type I(More)
OBJECTIVE The latent factor structure of posttraumatic stress disorder (PTSD) remains a source of considerable variability. The current study compared several a priori factor structures, as well as a novel 2-factor structure of posttraumatic psychological distress as measured by the Clinician Administered PTSD scale for the DSM-5 (CAPS-5). In addition,(More)
Data often have a nested, multilevel structure, for example when data are collected from children in classrooms. This kind of data complicate the evaluation of reliability and measurement invariance, because several properties can be evaluated at both the individual level and the cluster level, as well as across levels. For example, cross-level invariance(More)
The present study focuses on the development of citizenship competences of Dutch adolescents, including the political and social aspects as part of adolescents' daily lives. We followed 5070 adolescents aged 12-16 years across a three-year period in lower secondary education. The variance on school and student level was estimated and a three-level(More)
