[[alternative]]Research for preschooler language checklist

[[abstract]]本研究的目的在於，統整相關文獻並使用國民健康局兒童語言篩檢表的內容進行修改及增訂，作為學前兒童語言檢核表，並分析其信效度及篩檢準確度。期能在兒童就讀幼稚園時，使用此份檢核表，篩檢出具有語言發展遲緩的高風險兒童，轉介給專業人員做進一步的語言評估，確認兒童是否具有語言發展遲緩，以達到早期療育的成效。 在本研究中，研究者共招募107位滿四足歲的兒童及其家長，請家長填寫學前兒童語言檢核表，並且請兒童接受修訂學前兒童語言障礙評量表的施測，接著再進行在資料處理與分析。資料分析包括信效度及篩檢準確度的分析，信度分析將使用α係數信度進行分析，效度分析將使用內容效度以及同時效度進行分析。另外，以修訂學前兒童語言障礙評量表作為診斷效標，分析自編之學前兒童語言檢核表在不同的切截點的敏感度、特異度、陽性預測值、陰性預測值，以及擊中率，並找出最大的ROC曲線下面積，比較不同切截點所決定的整體準確度，求得整體準確度最佳的切截點。 研究針對學前兒童語言檢核表進行分析結果如下：(1)信度係數：α係數為.71，(2)語言理解、語言表達，及語言發展的效標關聯係數分別為：.20、.61、.55，皆為正相關，(3)切截分數為18分，ROC曲線下面積為.87，(4)敏感度為.88，特異度為.91，陽性預測值為.40，陰性預測值為.99，擊中率為.90。以上研究數據顯示出，學前兒童語言檢核表具有良好的信度及、效度，及篩檢準確度， 總結上述的研究結果及討論，學前兒童語言檢核表可作為提供快速篩檢出具語言發展遲緩兒童的檢核表，以及學前兒童語言發展能力的指標參考。[[abstract]]The purpose of study is to collect references and modify Bureau of Health Promotion Children Language Screening Test, and made of Preschooler Language Checklist. Researcher analyzed its reliability, validity, and screening accuracy. Hope clinicians could use this checklist to screen children with high risk of language development delay, and refer to professional to confirm. In the study, researcher recruited 107 4-year-old children and their parents. Parents have to fill out Preschooler Language Checklist, and children need to accept test of Modified Preschooler Language Scale. After we collect data, researcher analyzed reliability, validity, and screening accuracy. For analysis of reliability, researcher analyzed α reliability. For analysis of validity, researcher analyzed content validity and criterion-prediction validation. For analysis of screening accuracy, researcher analyzed sensitivity, specificity, positive predictive value, negative predictive value, and hit rate. Finally, researcher analyzed area under the curve(AUC) and decide the best cut-off score. The results data: (1)internal consistency reliability: α reliability coefficient .71, (2)criterion-prediction validity: .20、.61、.55, (3)cut-off score: 18, AUC: .87, (4)Sensitivity: .88, specificity: .91, positive predictive value: .40, negative predictive value: .99, hit rate: .90. In conclusion, preschooler language checklist include good reliability, validity, and accuracy of screening. It also could screen children of high risk language development delay
