ABSTRACT

INTRODUCTION The sentence comprehension test from the sentence comprehension cognitive examination (ECCO) battery can be used to assess children and adults with grammar comprehension disorders by means of a simple verification procedure that requires few memory resources.

AIM To present a psychometric analysis of the sentence comprehension test based on the classical theory of tests and on item response theory, as well as several studies that show its usefulness for assessing grammar comprehension in different populations.

SUBJECTS AND METHODS The test was applied to 2238 subjects with ages ranging from 6 to 85 years.

RESULTS The analysis shows that the test has a high overall reliability and, through the age groups that were considered, it includes elements that are especially discriminating or informative (lexical and syntactic distractors) and is biased towards medium-low levels of the trait.

CONCLUSIONS In view of the results, the sentence comprehension test from the ECCO battery provides a reliable measure of grammar comprehension through a wide variety of constructions and has great potential value for use in the clinical and research domains.
