today. These analyses involve the computation of sensitivity and specificity indexes and the receiver operating characteristic/area under the curve (ROC/AUC) statistic. DESCRIPTION OF THE TEST The test has four subtests, which require students to make inferences, interpret photographed scenes, and explain how they would resolve problems with peers. The Examiner’s Manual includes a comprehensive 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 individuals with normal language abilities and individuals who had previously been diagnosed with autism spectrum disorder. The average coefficient alpha ranges between .77 and .92 for the subtests and is .94 for the Social Language Development Index. Studies were conducted to examine the test’s ability to differentiate students who are autistic from those who are not. The results demonstrate that a Social Language Development Index cutoff score of 90 resulted in a sensitivity of .82, a specificity of .86, and a ROC/AUC of .91.

DESCRIPTION OF THE TEST The test has five subtests (Making Inferences, Interpreting Social Language, Problem Solving, Social Interpretation, and Interpreting Ironic Statements) that yield scaled scores. A composite score, called the Social Language Development Index, represents overall performance on the subtests. The Examiner’s Manual discusses the test’s theoretical and research-based foundation, item development, standardization, admin- istration and scoring procedures, normative tables, and guidelines for using and inter- preting 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. The average coefficient alpha ranges between .76 and .86 for the subtests and is .95 for the composite. New validity studies demonstrate the test’s ability to differentiate students with autism spectrum disorder from typically developing students. The results demonstrate that a Social Language Development Index cutoff score of 90 resulted in a sensitivity of .71, a specificity of .96, and a ROC/AUC of .90.

SLDT-E: NU: Social Language Development Test– Elementary: Normative Update Linda Bowers • Rosemary Huisingh • Carolyn M. LoGiudice

AGES: 6-0 through 11-11 TESTING TIME: 45 minutes ADMINISTRATION: Individual

The Social Language Development Test– Elementary: Normative Update (SLDT-E: NU) assesses the language-based skills of social interpretation and interaction with friends, the skills found to be most predictive of social language development. Specifically, it measures the language required to appropri- ately infer and express what another person is thinking or feeling within a social context, make multiple interpretations, take mutual

perspectives, and negotiate with and support peers. These tasks reflect the develop- mental refinement of social language comprehension and expression and differentiate typically developing children from those with autism spectrum disorder. FEATURES • Updated norms based on the 2015 U.S. Census. • New standard score metric for subtests and composites ( M = 10, SD = 3; and M = 100, SD = 15, respectively). • All-new item analysis and item bias studies provide convincing evidence of content- description validity. • All-new reliability and validity studies were prepared, including diagnostic accuracy analyses, which are considered the most rigorous techniques for establishing validity

SLDT-A: NU: Social Language Development Test– Adolescent: Normative Update Rosemary Huisingh • Linda Bowers • Carolyn LoGiudice

AGES: 12-0 through 17-11 TESTING TIME: 45 minutes ADMINISTRATION: Individual

The Social Language Development Test– Adolescent: Normative Update (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. FEATURES

• The norms have been updated to reflect the demographics of the 2016 U.S. Census. • The normative sample ( N = 868) is stratified by age relative to geographic region, gender, race, and ethnicity. • New standard score metric for subtests and composites ( M = 10, SD = 3; and M = 100, SD = 15, respectively). • All-new item analysis and item bias studies provide convincing evidence of content- description validity. • All-new reliability and validity studies were prepared, including diagnostic accuracy analyses, which are considered the most rigorous techniques for establishing validity today. These analyses involve the computation of sensitivity and specificity indexes and the receiver operating characteristic/area under the curve (ROC/AUC) statistic. • The audio files for the Interpreting Ironic Statements subtest are available for use or download online.
