To present evidence of the validity and reliability of a phonological assessment tool developed to assess the phonological inventory of Brazilian Portuguese.
The study included 866 children aged between 3 and 8:11 years, divided into three groups: typical, control and clinical. Participants were evaluated using a phonological assessment software, which prompted the spontaneous naming of a series of images. The children's responses were audio recorded and transcribed at the time of the assessment, by the software itself. The Cronbach's alpha coefficient was used to evaluate the internal consistency of the instrument for reliability and validity purposes. Criterion validity was examined by comparing the performance of different groups using Student's t-test for independent samples. Intra- and inter-rater agreement were investigated using Kendall's tau. Results were considered significant at p ≤ 0.05.
The present study provided evidence of validity and reliability (internal consistency) for this phonological assessment tool, confirming the reliability of its items and demonstrating excellent agreement rates between examiners regarding its scoring (intra- and inter-rater reliability). The criterion validity assessment demonstrated that the control group outperformed the clinical group across all phonemes, showing that test scores were successful in identifying children with speech sound disorders (phonological disorders).
The present findings provide strong evidence of the validity and reliability of this phonological assessment tool.
提供一种为评估巴西葡萄牙语音位清单而开发的语音评估工具的有效性和可靠性的证据。
该研究纳入了866名年龄在3岁至8岁11个月之间的儿童，分为三组：典型组、对照组和临床组。使用语音评估软件对参与者进行评估，该软件促使他们自发说出一系列图像的名称。儿童的回答在评估时由软件本身进行录音和转录。使用克朗巴哈系数来评估该工具在可靠性和有效性方面的内部一致性。通过使用独立样本的学生t检验比较不同组的表现来检验标准效度。使用肯德尔tau系数研究评分者内和评分者间的一致性。结果在p≤0.05时被认为具有显著性。
本研究为这种语音评估工具提供了有效性和可靠性（内部一致性）的证据，证实了其项目的可靠性，并表明检查者之间在评分方面（评分者内和评分者间可靠性）具有出色的一致率。标准效度评估表明，对照组在所有音素上的表现均优于临床组，表明测试分数成功地识别出了有语音障碍（音位障碍）的儿童。
本研究结果为这种语音评估工具的有效性和可靠性提供了有力证据。
