Normative Values and Test/Retest Reliability of a New Test: Spatial Processing of Sentences in Noise in Portuguese

Objective: This article establishes normative values for children and analyzes test-retest results for a new test, the Spatial Processing of Sentences in Noise in Portuguese (PROSER). Methods: To establish normative criteria, we evaluated 66 Brazilian Portuguese-speaking children aged 7-10 years using audiological assessments, school performance tests, and the PROSER test. A subset of 22 children participated in a test-retest evaluation. Results: Examining all 66 participants, we found significant differences in the speech reception threshold (SRT) means between the 0° and ±90° interference conditions when analyzing all four test conditions. Considering the age group, the performance of 10-year-old children was superior to that of both 7- and 8-year-old children. Test-retest comparison showed slight improvements (0.11-1.13 dB) in the retest phase across most conditions and advantage measures. The difference between the average SRT in the test and retest was statistically significant only in Condition 3-DV0°. Conclusions: The study established normative values for children aged 7-10 years, confirming PROSER as a procedure with adequate test-retest reliability.
