Efficacy of the social-emotional learning foundations curriculum for kindergarten and first grade students at risk for emotional and behavioral disorders.

Researchers have shown that children's social-emotional growth is inextricably connected to academic learning. We developed the Social-Emotional Learning Foundations (SELF) intervention, a Grade K-1 curriculum merging social-emotional learning (SEL) and literacy instruction, to promote language supported self-regulation, specifically for primary grade children at early risk for emotional or behavioral difficulties. We report findings from a pretest-posttest cluster randomized efficacy trial with one fixed between-subjects factor to test the effects of teacher-delivered SEL instruction against those of business as usual (BAU).

Comparison of model- and design-based approaches to detect the treatment effect and covariate by treatment interactions in three-level models for multisite cluster-randomized trials.

In this study, we evaluated the estimation of three important parameters for data collected in a multisite cluster-randomized trial (MS-CRT): the treatment effect, and the treatment by covariate interactions at Levels 1 and 2. The Level 1 and Level 2 interaction parameters are the coefficients for the products of the treatment indicator, with the covariate centered on its Level 2 expected value and with the Level 2 expected value centered on its Level 3 expected value, respectively. A comparison of a model-based approach to design-based approaches was performed using simulation studies.

Factors Associated with Teacher Delivery of a Classroom-Based Tier 2 Prevention Program.

Teachers sometimes struggle to deliver evidence-based programs designed to prevent and ameliorate chronic problem behaviors of young children with integrity. Identifying factors associated with variations in the quantity and quality of delivery is thus an important goal for the field. This study investigated factors associated with teacher treatment integrity of BEST in CLASS, a tier-2 prevention program designed for young children at risk for developing emotional/behavioral disorders.

Examining young children's social competence using functional ability profiles.

Purpose: To explore the use of International Classification of Functioning, Disability, and Health for Children and Youth (ICF-CY) based profiles of children's functional abilities in relation to their social competence. Subgroups based on shared profiles of functional ability were investigated as an alternative or complement to subgroups defined by disability categories.

Methods: Secondary analysis of a nationally representative data set of young children identified for special education services in the United States was used for the present study.

The Effects of Including Observed Means or Latent Means as Covariates in Multilevel Models for Cluster Randomized Trials.

We investigated methods of including covariates in two-level models for cluster randomized trials to increase power to detect the treatment effect. We compared multilevel models that included either an observed cluster mean or a latent cluster mean as a covariate, as well as the effect of including Level 1 deviation scores in the model. A Monte Carlo simulation study was performed manipulating effect sizes, cluster sizes, number of clusters, intraclass correlation of the outcome, patterns of missing data, and the squared correlations between Level 1 and Level 2 covariates and the outcome.
