The aim of the study was to validate the Brazilian-Portuguese version of the Intelligibility in Context Scale (ICS-BP).
Sixty children (mean age in months = 55.05, SD = 4.2), 15 with parental or teacher concerns regarding their speech and 45 without concerns, underwent assessment using the phonology subtest of ABFW - Child Language Test. The percentage of consonants correct (PCC) was calculated and parents completed the ICS to evaluate their children's intelligibility with various communication partners. Descriptive statistics were obtained. Kruskal-Wallis and Spearman' tests were used for independent group comparisons and correlation calculations, respectively. Linear regression models were established to predict PCC. Internal consistency was calculated using Cronbach's alpha. A Receiver Operating Characteristic (ROC) was used to analyse sensitivity and specificity. Significance was considered for p-values under 0.05.
The majority of parents reported a mean score of 4.6 in a total of 5 (SD .10) at the ICS responses with different listeners, with better performance with other acquaintances and members of the family. The ICS demonstrated excellent internal consistency (α = 0.95). Positive correlations were found between ICS scores and PCC (r = .790) and a simple linear model was established between the ICS mean score and PCC. Sensitivity (0.98) and specificity (0.87) were considered high.
The ICS-BP indicated high psychometric values, suggesting that this instrument can be used to measure the intelligibility of Brazilian children.
本研究旨在验证巴西葡萄牙语版的情境可懂度量表（ICS-BP）。
60名儿童（平均年龄为55.05个月，标准差=4.2），其中15名儿童的父母或教师对其言语表示担忧，45名儿童无此担忧，使用ABFW儿童语言测试的语音分测验进行评估。计算辅音正确百分比（PCC），父母完成ICS以评估孩子与不同交流伙伴交流时的可懂度。获得描述性统计数据。分别使用Kruskal-Wallis检验和Spearman检验进行独立组比较和相关性计算。建立线性回归模型以预测PCC。使用Cronbach's alpha计算内部一致性。使用受试者工作特征曲线（ROC）分析敏感性和特异性。p值小于0.05时认为具有统计学意义。
大多数父母报告在ICS中与不同听众的回答中，总分为5分（标准差0.10）时平均得分为4.6分，与其他熟人及家庭成员交流时表现更好。ICS表现出出色的内部一致性（α = 0.95）。ICS得分与PCC之间存在正相关（r = 0.790），并在ICS平均得分与PCC之间建立了简单线性模型。敏感性（0.98）和特异性（0.87）较高。
ICS-BP显示出较高的心理测量学价值，表明该工具可用于测量巴西儿童的可懂度。
