隨著社會進入超高齡化階段，日間照顧服務環境的品質對提升受照顧者的生活品質與滿意度至關重要。本研究旨在建構並驗證一份具標準化、信效度良好且操作性高的綜合性服務環境量表，以自服務使用者觀點系統性評估日照場域環境品質與理想與現實間的落差。研究分為兩階段：第一階段透過文獻回顧與專家效度檢驗建構初步量表；第二階段採用橫斷式調查設計，蒐集南臺灣31家日照立案機構670份有效問卷，研究對象為混合式日照之服務使用者（同時涵蓋失能與失智長者），然而，探索性因素分析（EFA）結果顯示，「氛圍」構面內部題項再細分為三個穩定因子，分別為「自然環境」、「美學與文化」及「永續生活」。因此，本研究最終修正為五大構面之量表，共24題項。各構面均具備良好的信效度，Cronbach’s α分別為0.971、0.948及0.957，總解釋變異量分別為65.6%、63.2%與67.3%。驗證性因素分析（CFA）及結構方程模型（SEM）顯示量表具良好的模型適配度（GFI=0.908，AGFI=0.886，RMSEA=0.057，CFI=0.959，NFI=0.942，TLI=0.954，IFI=0.959，PNFI=0.829，χ²/df=3.176，Hoelter’s N=244），並通過收斂效度（AVE>0.634）與複合信度（CR>0.775）檢驗。

With the advent of a super-aged society, the quality of adult day care centers is crucial for promoting older adults’ well-being and satisfaction. The purpose of this study is to develop and validate a standardized, user-centered environmental quality scale that can bridge the gap between ideal and actual service conditions. Phase 1 involved literature review and expert evaluation; Phase 2 used a cross-sectional survey of 670 valid responses from 31 centers in southern Taiwan, all mixed-care facilities serving both frail and dementia elders, analyzed through exploratory factor analysis (EFA). The preliminary analysis identified three dimensions—Physical Environment, Service Function, and Atmosphere. Atmosphere was further divided into Natural Environment, Aesthetics & Culture, and Sustainable Living, yielding a final five-factor, 24-item scale. Each dimension showed high reliability (Cronbach’s α = 0.948–0.971) and strong construct validity (variance explained = 63.2%–67.3%). Confirmatory factor analysis (CFA) and structural equation modeling (SEM) confirmed good model fit (CFI = 0.959; RMSEA = 0.057), with convergent validity (AVE > 0.634) and composite reliability (CR > 0.775). This validated scale provides a rigorous tool for quality monitoring, spatial design optimization, and evidence-based policy in adult day care settings.
