Utility of the social skills improvement system-rating scales for capturing dynamic social constructs: Evidence using the measurement model of derivatives.

Social skills are dynamic developmental constructs typically measured using assessments developed via cross-sectional methods. The measurement model of derivatives (MMOD), a factor analytic approach targeting individual growth trajectories, was used to evaluate the longitudinal factor structure of the Social Skills Improvement System-Rating Scales (SSIS-RS) teacher form with a sample of 1320 first and second grade students (51.6% female, 54.

Using a person-centered analysis to examine second-grade outcomes of a universal SEL program.

Effective universal social skills programs are intended to facilitate the development of students' social competencies and enhance classroom learning. As such, the present study sought to provide additional insights and a more nuanced understanding of the impacts of one such universal program, the Social Skills Improvement System Classwide Intervention Program (SSIS-CIP; Elliott & Gresham, 2007). Using a person-centered data analytic approach, we evaluated SSIS-CIP's association with heterogeneity in patterns of change on social skills and problem behavior measures over time for second-grade students.

Multi-informant validity evidence for the SSIS SEL Brief Scales across six European countries.

The SSIS SEL Brief Scales (SSIS SEL) are multi-informant (teacher, parent, and student) measures that were developed to efficiently assess the SEL competencies of school-age youth in the United States. Recently, the SSIS SEL was translated into multiple languages for use in a multi-site study across six European countries (Croatia, Greece, Italy, Latvia, Portugal, and Romania). The purpose of the current study was to examine concurrent and predictive evidence for the SEL Composite scores from the translated versions of the SSIS SEL Scales.

Newborn Screening for X-Linked Adrenoleukodystrophy in Nebraska: Initial Experiences and Challenges.

X-linked adrenoleukodystrophy (X-ALD) is a neurodegenerative disease caused by pathogenic variants in resulting in defective peroxisomal oxidation of very long-chain fatty acids. Most male patients develop adrenal insufficiency and one of two neurologic phenotypes: a rapidly progressive demyelinating disease in mid-childhood (childhood cerebral X-ALD, ccALD) or an adult-onset spastic paraparesis (adrenomyeloneuropathy, AMN). The neurodegenerative course of ccALD can be halted if patients are treated with hematopoietic stem cell transplantation at the earliest onset of white matter disease.
