本研究的目的是评估欧洲-葡萄牙语版本的上下文可理解性量表（ICS-EP）的有效性、可靠性、敏感性和特异性。（年龄：M = 60.6，SD = 8.1个月），25名家长或老师关心他们的谈话方式，51名不关心，用语音-音韵学测试（TFF-ALPE）评估，以计算以下严重性指标：音素正确率（PPC）、辅音正确率（PCC）和元音正确率（PVC）。父母还填写了一份关于孩子发展的问卷（例如，对孩子如何说话的关注）。结果表明，不同的交际对象在项目水平上的得分存在差异。整个样本的平均ICS评分为4.5（SD = 0.6），表明儿童“通常”到“总是”可理解。ICS具有良好的内部一致性（α = 0.96）。父母关心他们的语言的儿童提出了显着较低的平均得分（M = 3.91，SD = 0.59）比儿童没有父母的关注（M = 4.78，SD = 0.36）。ICS评分与PPC（r = 0.655）、PCC（r = 0.654）和PVC（r = 0.588）之间呈正相关。ICS平均评分和分析的严重程度指标之间也获得了一个简单的线性模型。结果表明，ICS-EP具有良好的心理测量学特性，可以作为评估儿童与不同交际对象交谈时可懂度的有效工具。因此，该版本的ICS可以用作儿童语言清晰度的筛查措施。
The purpose of the study was to evaluate the validity, reliability, sensitivity and specificity of the European-Portuguese version of the Intelligibility in Context Scale (ICS-EP).Seventy-six children (age: M = 60.6, SD = 8.1 months), 25 having a parent or teacher concern about how they talked and 51 with no concern, were assessed with the phonetic-phonological test (TFF-ALPE) to calculate the following severity measures: percentage of phonemes correct (PPC), percentage of consonants correct (PCC), and percentage of vowels correct (PVC). Parents also filled out a questionnaire about their child's development (e.g. concern about how the child talks). The ICS was then completed by parents to estimate their children's intelligibility with different communicative partners.The results showed that item-level scores were different according to communicative partners. The mean ICS score for the whole sample was 4.5 (SD = 0.6), showing that children were "usually" to "always" intelligible. The ICS had excellent internal consistency (alpha = 0.96). Children with parental concern about their speech presented significantly lower mean scores (M = 3.91, SD = 0.59) than children without parental concerns (M = 4.78, SD = 0.36). There was a positive correlation between the ICS scores and PPC (r = .655), PCC (r = .654), and PVC (r = .588). A simple linear model was also obtained between the ICS mean score and the severity measures analyzed. High values were obtained for sensitivity (0.80) and specificity (0.84), using a cut-off point of 4.36.We conclude that the ICS-EP has good psychometric properties, suggesting it to be a valid tool for estimating children's intelligibility when talking with different communicative partners. Therefore, this version of the ICS can be used as a screening measure for children's speech intelligibility.
