The present study aimed to evaluate the psychometric properties of the Persian version of the Phoneme Recognition Test (P-PRT) in normal subjects and cochlear implant (CI) users.
MATERIAL & METHODS: This study includes developing the Persian phoneme recognition test (PRT), determining its validity and reliability, and comparing the results of a control group versus CI users. The test reliability was examined through a test-retest with an approximately five-week interval. In the present survey, 363 subjects were investigated in three stages. The face validity evaluation stage was conducted on 40 subjects. The psychometric properties of the P-PRT were evaluated in 323 individuals (225 normal subjects and 98 CI users). The test-retest reliability was examined in all the 225 subjects in the control group and 40 CI users.
The results confirmed the face validity of the P-PRT. No significant differences were observed between the two genders in terms of performance in the P-PRT. Significant differences were observed between the control and CI groups. Evaluating the test-retest reliability suggested perfect reliability (r>0.9) in both groups. Significant differences were observed in the P-PRT between the adults and the 7-year-old subjects compared to other age groups.
The P-PRT can be used as a valid and reliable test for clinically evaluating phoneme recognition abilities and monitoring the rehabilitation progress.
本研究旨在评估波斯语版音素识别测试（P-PRT）在正常受试者和人工耳蜗（CI）使用者中的心理测量特性。
本研究包括开发波斯语音素识别测试（PRT）、确定其有效性和可靠性，以及比较对照组与CI使用者的结果。通过间隔约五周的重测来检验测试的可靠性。在本次调查中，分三个阶段对363名受试者进行了研究。在40名受试者身上进行了表面效度评估阶段。在323名个体（225名正常受试者和98名CI使用者）中评估了P-PRT的心理测量特性。在对照组的所有225名受试者和40名CI使用者中检验了重测可靠性。
结果证实了P-PRT的表面效度。在P-PRT的表现方面，两性之间未观察到显著差异。对照组和CI组之间观察到显著差异。评估重测可靠性表明两组的可靠性都极佳（r>0.9）。与其他年龄组相比，成年人和7岁受试者在P-PRT方面存在显著差异。
P-PRT可作为临床上评估音素识别能力和监测康复进展的有效且可靠的测试。
