The Perceived Restorative Scale (PRS) is widely used in restorative environments evaluation. As its Chinese version hasn't been tested in landscape evaluation of urban parks, this paper studied the reliability and validity of the Chinese PRS in evaluating the restorative qualities of scenes in urban parks. Videos of scenes with different elements, openness, with or without people were taped. Altogether 120 college students, with an equal number of males and females, participated in this experiment. They first took an oral English test as a stressor, and then watched one of the six landscape videos for stress recovering. Subjects rated the Chinese PRS based on the scene they watched. The results showed the Chinese PRS had a high inter-rater reliability, and the internal consistency reliability was acceptable. The correlations between the overall score and scores of the items were significant. According to the result of the exploratory factor analysis, the scale construct was generally coherent with the Attention Restorative Theory. The rating results also showed there were significant differences between different urban park scenes. It suggests the Chinese version of the PRS can be used in evaluating restorative qualities of urban park landscapes.
