目標：探討桃園縣以網際網路為基礎之早期療育資訊系統使用效益與影響因素。方法：以影響早期療育資訊系統使用效益之因素結構式問卷對公共衛生、醫療及教保等單位使用人員進行量測，評估系統使用效益與影響因素，進行階層多元迴歸分析。共485個單位，總計發出970份問卷，問卷回收率32%，其中以幼稚園最多，計126份（41.0%），其次依序為托兒所80份（26.1%）、醫療單位65份（21.2%）、衛生單位36份（11.7%）。結果：發現使用人員對早期療育資訊系統使用效益認同程度高，其資訊使用（M=3.94；SD=0.61）、使用者滿意度（M=4.14；SD=0.62）、個人決策品質（M=4.16；SD=0.58）、組織生產力（M=4.15；SD=0.58）。結論：當單位使用者對系統使用效益影響因素（包括：組織內行政流程簡化程度、不同機構間發揮本身專業能力分工整合程度、對衛生法令規範之認知、對獎勵制度執行之認知）認同程度越高時，則系統使用效益（包括：資訊使用、使用者滿意度、個人決策品質、組織生產力）就越好。

Objectives: The aim of this study was to explore factors in the utilization of an early intervention for children with developmental delays information system, a web-based system accessed from the Internet, in Taoyuan County. Methods: A structured questionnaire was designed and used to survey the users of ECMS (Early Childhood Helthcare Managment Information System) and hierarchical multiple regression analysis was then conducted. A total of 970 questionnaires were sent out and 307 valid questionnaires (32%) were returned. The units that responded most were kindergartens with 126 questionnaires (41.0%), followed by nurseries, 80 (26.1%), medical units, 65 (21.2%), and public health units, 36 (11.7%). Results: Factors in the utilization of the early intervention for children with developmental delays information system were: information use (M=3.94; SD=0.61), user satisfaction (M=4.14; SD=0.62), individual decision-making quality (M=4.16; SD=0.58), and organizational productivity (M=4.15; SD=0.58). Conclusions: When users agree more with the "degree of simplification of administrative processes within the organization", "degree of integration among different professional institutions", "knowledge about sanitary laws and norms", and "knowledge about reward system implementation", they used the system more effectively.
