Examining the Impacts of Green and Blue Biophilic Landscapes on University Students’ Stress and Anxiety Zhang, John; Duhra, Raveen; Liu, Sandy; Li, Sichan; Shi, Yanbing; Cao, Yixin


The current study explored how viewing green or blue biophilic outdoor landscapes impacts university students’ stress and anxiety? To operate the study, we hypothesized that a combination of green and blue biophilic landscapes would reduce stress and anxiety to a greater extent than individual elements or non-biophilic urban landscapes. We conducted an online experiment using a between-subject design on the UBC Qualtrics Platform. Participants were randomly assigned to one of the four conditions with different pictorial window views (ocean view, forest view, combined view and urban view) and asked to imagine studying and living in the environments shown in the pictures. Their stress and anxiety levels were measured using the Depression Anxiety Stress Scale (DASS-21) questionnaire. An one-way between groups ANOVA and post hoc Turkey test revealed that participants in the forest view condition showed the greatest reduction of stress and anxiety, followed by the ocean view and combined view condition. Therefore, the results do not support our hypothesis. This can be due to the lack of ecological validity of pictures used and sampling bias. The current research can be applied to future residential zoning plans at UBC to maximize the forest and ocean views exposed to students.
