背景：2012年，情境可理解性量表（ICS）作为一项家长报告筛选评估发布，该评估考虑了父母对孩子在现实生活中与一系列交流伙伴的功能可理解性的看法，这些交流伙伴在权威和熟悉程度上存在差异。到目前为止，ICS已被翻译成60种语言（包括德语）。目的：采用语音障碍（SSD）严重程度的四个客观测量指标：辅音正确率（PCC）；初始辅音正确率（PICC）；元音正确率（PVC）；以及音素正确率（PPC）。方法与步骤：通过德国13所幼儿园和15名言语语言病理学家（slp）招募典型发育儿童（TD）和SSD儿童（n = 181，男90，女81，平均年龄4.18岁，SD = 0.79岁，范围= 3;0-5；11岁）。所有孩子的父母都完成了ICS-G。为了深入了解SSD的严重程度（n = 30），使用PLAKSS-II评估儿童的语言技能。为了分析重测信度，在1周后，对父母（n = 36）的子样本重新使用ICS-G。结果与结果：ICS-G具有较高的内部一致性（= .95,p < .001）和较高的重测信度（r = .998, p < .001）。两个样本的ICS-G总分和单项得分呈显著相关，表明具有良好的结构效度。分析显示，与外部因素（如年龄、社会阶层）的相关性虽低，但显著。通过ICS-G与PCC （r = 0.43）、PICC （r = 0.43）、PVC （r = 0.62）和PPC （r = 0.47）得分之间的显著相关，建立了标准效度。TD组的平均评分（mean = 4.49, SD = 0.47）显著高于SSD组（mean = 3.97, SD = 0.63），表明了ICS-G的区分能力。结论和意义：ICS-G的总体良好的心理测量特性支持slp将其用于德语儿童的临床和研究目的。
Background: In 2012 the Intelligibility in Context Scale (ICS) was published as a parent-report screening assessment that considers parents' perceptions of their children's functional intelligibility with a range of communication partners that differ in levels of authority and familiarity in real-life situations. To date, the ICS has been translated into 60 languages (including German).Aims: To evaluate the psychometric properties of the German translation of the ICS ( = ICS-G), especially its reliability and validity, using four objective measures of speech sound disorder (SSD) severity: percentage of consonants correct (PCC); percentage of initial consonants correct (PICC); percentage of vowels correct (PVC); and percentage of phonemes correct (PPC).Methods & Procedures: Children who were typically developing (TD) and children with SSD (n = 181; 90 males, 81 females; mean age = 4.18 years, SD = 0.79 years, range = 3;0-5;11 years) were recruited through 13 kindergartens and 15 speech-language pathologists (SLPs) in Germany. All children's parents completed the ICS-G. To obtain an insight into the severity of SSD (n = 30), children's speech skills were assessed with PLAKSS-II. For the analysis of test-retest reliability the ICS-G was re-administered with a subsample of parents (n = 36) after 1 week.Outcomes & Results: The ICS-G had high internal consistency ( = .95, p < .001) and high test-retest reliability (r = .998, p < .001). The ICS-G total scores and item scores for both samples showed significant correlations, indicating good construct validity. Analyses revealed low but significant correlations with external factors (e.g., age, social class). Criterion validity was established through significant correlations between the ICS-G and scores for PCC (r = .43), PICC (r = .43), PVC (r = .62) and PPC (r = .47). The discriminatory ability of the ICS-G was indicated by significantly higher mean scores for the TD group (mean = 4.49, SD = 0.47) than the SSD group (mean = 3.97, SD = 0.63).Conclusions & Implications: The overall good psychometric properties of the ICS-G support its use by SLPs for clinical and research purposes with German-speaking children.
