本研究目的在探討日照場域之實質環境、服務機能與氛圍三構面對高齡者幸福感與療癒感的影響。研究採橫斷式問卷調查法，回收670份有效樣本，並使用信效度驗證後之量表進行資料收集，再以多元線性迴歸建構雙模型分析。結果顯示，療癒感與幸福感具顯著中度正相關（r = .594，p < .001），其中療癒感模型（R² = 0.646）解釋力高於幸福感模型（R² = 0.270），顯示高齡者對場域環境之心理感知具即時反應特性。 在預測因子方面，「氛圍構面」對心理福祉影響最顯著，自變項中「自立促進」（β = 0.64）、「美學文化」（β = 0.53）與「永續生活」（β = 0.30）具穩定正向效果；「空間配置」、「個別化照顧」與「美學文化」亦對幸福感具中度正向影響。相對地，「照顧服務」（β = -0.13）與「安全舒適」（β = -0.14）在部分模型中呈負向預測，反映過度控制與保護可能抑制自主性與主體感。儘管「自然環境」具理論潛力，但實證顯示其預測力有限，顯見文化氛圍與參與經驗更為關鍵。 研究結果支持注意力恢復理論（ART）與自我決定理論（SDT）於高齡照顧場域的應用。實務建議提升美感參與、自主選擇與支持性氛圍，從而強化日照場域對療癒與幸福經驗的促進功能。

This study investigates how the built environment, service functions, and spatial atmosphere of adult day care centers affect the psychological well-being of older adults. Based on 670 valid questionnaires, two regression models were developed to analyze the effects on healing experience and subjective well-being (SWB). Healing and SWB were moderately correlated (r = .594, p < .001). Healing experience showed higher explanatory power (R² = 0.646) than SWB (R² = 0.270), suggesting stronger environmental sensitivity. Key predictors included autonomy support (β = 0.64), aesthetic-cultural atmosphere (β = 0.53), and sustainable living (β = 0.30), while care services (β = -0.13) and safety-comfort (β = -0.14) had negative effects. Although natural environments are theoretically restorative, they showed limited empirical influence. The findings support integrating Attention Restoration Theory (ART) and Self-Determination Theory (SDT) into aging-friendly design, emphasizing atmospheric quality and autonomy-enhancing features to improve psychological outcomes.
