In children with a hearing loss who receive cochlear implants (CIs) under the age of 2, regular assessments are conducted to monitor auditory and linguistic progress. However, the collection of authentic, representative, and reliable expressive language data on young children with CIs remains a challenge. The purpose of the study was to determine…

This review examines published secondary analyses of National Longitudinal Transition Study 2 (NLTS2) data, with a primary focus upon statistical objectives, paradigms, inferences, and methods. Its primary purpose was to determine which statistical techniques have been common in secondary analyses of NLTS2 data. The review begins with an…

Objective: To identify trajectories of behavioral adjustment from age 6 through 14 years for youth placed in early foster care, and to examine links between trajectories and early cognitive ability and social competence, caregiver stability, and frequency, timing, and type of maltreatment. Method: Participants were 279 youth from the Southwest…

Background: A functional polymorphism in the promoter region of the monoamine oxidizing gene "monoamine oxidase A" ("MAOA") has been associated with behavioral sensitivity to adverse environmental conditions in multiple studies (e.g., Caspi et al. 2002; Kim-Cohen et al., 2006). The present study investigates the effects of…

Background: Children's early problem behavior that manifests in multiple contexts is often more serious and stable. The concurrent and predictive validity of ratings of externalizing and internalizing by four informants was examined at preschool and early school age in an at-risk sample. Methods: Two hundred forty children were assessed by mothers…

This research investigated the effects of two contrasting pre-k curricula, relative to practice as usual, on subsequent academic achievement. One curriculum had a strong literacy focus, the other was a less didactic "developmentally appropriate" curriculum that allowed children to have more influence on classroom activities. The purpose…

Standardized rating scales are the most often used part of the multidimensional assessment of children's behavior. However, low cross-informant correlations raise concerns about the reliability and validity of the resulting scores. This study examined whether the manner in which behavioral constructs are measured differs across informants, across…
