(SLDT-A: NU) Social Language Development Test–Adolescent: Normative Update
by
Norms
Based on a sample of 868 individuals, stratified by age relative to geographic region, gender, race, and ethnicity
Benefit
Measures language-based skills of social interpretation and interaction to differentiate typically developing students from those diagnosed with autism spectrum disorder
The SLDT-A: NU assesses language-based social skills. Specifically, it measures students’ ability to make inferences and interpret and respond to social interaction. Performance on the test differentiates typically developing students from those with autism spectrum disorder.
New Features
Updated norms that reflect demographics of the 2016 U.S. Census
Normative sample (N = 868) stratified by age relative to geographic region, gender, race, and ethnicity
New standard score metric for subtests and composites (M = 10, SD = 3; M = 100, SD = 15)
All-new item analysis and item bias studies providing convincing evidence of content-description validity
All-new reliability and validity studies, including diagnostic accuracy analyses (considered the most rigorous techniques for establishing validity)
Audio files for Interpreting Ironic Statements subtest available for online use or download
Description of the Test
The SLDT-A: NU has five subtests (Making Inferences, Interpreting Social Language, Problem Solving, Social Interpretation, and Interpreting Ironic Statements) that yield scaled scores. A composite score, the Social Language Development Index, represents overall performance on the subtests. The Examiner’s Manual includes a discussion of the test’s theoretical and research-based foundation, item development, standardization, administration and scoring procedures, norms tables, and guidelines for using and interpreting the test’s results. Reliability and validity studies were conducted with students with typical language abilities and students who had previously been diagnosed with autism spectrum disorder.
