復癒性景觀知覺與效益量表驗證

An Exploratory Study on Restorative Landscape Perception and Benefit Measurement Scales

本研究目的為驗證復癒知覺量表，與復癒效益量表。復癒知覺部份採用戴大為所提出的恢復性環境特徵量表，共19題；在復癒效益部份，經由文獻蒐集研擬出復癒效益量表，共20題。選擇台中慈濟醫院中庭為研究基地，依據復癒景觀設計準則，製作成4分鐘復癒景觀模擬影片，以逢甲大學在校學生進行實證研究，共643份有效樣本。透過驗證性因素分析結果顯示，復癒知覺四個構面對復癒知覺的影響程度，以構面延展性解釋力最高（λ＝0.93），最低為遠離性（λ＝0.85）；復癒效益四個構面對復癒效益的影響程度，以構面直接注意力之恢復解釋力最高（λ＝0.89），最低為認知上的平靜（λ＝0.61）。研究結果驗證復癒知覺量表以及復癒效益量表均具有信效度，可應用於後續相關研究中。

This study validates the restorative measurement scale and the restorative benefits scale. The restorative measurement scale comprising 19 questions was developed by Kaplan and Kaplan (1989) and revised by Dai Da Wei (2013). The scale for restorative benefits was developed by reviewing literature and produced 20 items. The study selected Taichung Tzu-Chi Hospital as the research base. Based on the design criteria of the restored landscape, a four-minute restored landscape simulation film was produced, and data were collected from Feng Chia University students. A total of 643 valid questionnaires were obtained. Confirmatory factor analysis was conducted for both scales; the restorative measurement scale retained 15 items, and the restorative benefits scale retained 11 items. Of the four dimensions for restoration, Extent had the most powerful ability (λ=0.93), and Being Away had a lower capability (λ=0.85); of the four dimensions for the restoration benefits, Recovery Directed Attention had the most powerful ability (λ=0.89), and Cognitive Quiet had a lower capability (λ=0.61). The results confirm the reliability and validity of the restorative measurement and restorative benefits scales for use in subsequent related studies.
