Development, validity, reliability and normative data of the Persian Phonemic Synthesis Test (P-PST).

Area of Science:

• Speech and Language Pathology
• Auditory Processing Research
• Psychometrics

Background:

• Auditory processing disorders (APD) can impact language development.
• Standardized tests are crucial for accurate diagnosis.
• A Persian version of the Phonemic Synthesis Test was needed.

Purpose of the Study:

• To develop and validate the Persian version of the Phonemic Synthesis Test.
• To establish its psychometric properties, including reliability and validity.
• To generate normative data for Persian-speaking children.

Main Methods:

• Test development involved material optimization, content, and face validity assessments.
• Psychometric properties were evaluated in 395 children aged 7-11.
• Test-retest reliability was assessed over four weeks.

Main Results:

• The Persian Phonemic Synthesis Test demonstrated strong content and face validity.
• No significant gender differences were found; age-related differences were significant.
• High test-retest reliability (r > 0.9) and similarities to the original American test were observed.

Conclusions:

• The Persian Phonemic Synthesis Test is a reliable and valid measure.
• It is suitable for auditory processing assessments in Persian-speaking children.
• Normative data support its clinical application.
