Urban green space preferences for various health-related psychological benefits of adolescent pupils, university students and adults

Abstract

Previous research has shown that biophysical and social characteristics of urban green spaces (UGS) and individual factors may play a role in preferences for restorative environments. However, little is known about the trade-offs between (bio)physical and social characteristics of UGS on different health-related psychological benefits between different population groups. This exploratory study used an image-based discrete choice experiment, in which 298 adolescent pupils, 159 university students, and 142 adults were asked which urban green spaces they would prefer for general recovery, stress reduction, and concentration improvement. Each of the 128 green space scenarios depicted different attributes of varying levels of recreational infrastructure, numbers of trail users, distances between forest vegetation and trail, traffic noise, background scenery, both in winter and in summer. The results indicate that visitor numbers and traffic noise strongly influenced green space preferences for all study groups, but groups differed in terms of their preferences and trade-offs for the psychological benefits. The biophysical environment was less important for adolescent pupils, while recreational infrastructure was less important for the adults. There were group differences in stated preferences for general recovery, stress reduction, and concentration enhancement. Implications for urban green space planning are presented.
