抄録

The coronavirus pandemic has led workers to remote work. This study aimed to elucidate the effect of working in green spaces in a summer nearby office in 3 experiment days and analyzed effects according to the trait anxiety tendencies, i.e., High-anxiety and Low-anxiety groups. The subjects were 27 who worked in offices nearby the experimental site (11 male and 16 female) aged from 20s to 30s. The experimental site was greened for an event in Marunouchi, Tokyo. The Visual Analog Scale results indicated that working in green spaces significantly improved workers’ subjective psychological statuses, such as “vigor,” “tension- anxiety,” and “mood,” and the questionnaire survey revealed subjective evaluations of job state, such as “enjoy” and “think deeply.” To consider effectiveness based on participants’ anxiety trends, divided participants into two groups using the score of (Y-2) in the State-Trait Anxiety Inventory. Increasing working in a green space was likely more effective for the low-anxiety group. The high-anxiety group’s subjective psychological evaluation of work status tended to improve the most by the first time working in green spaces. These observations suggested that using green spaces as a workplace provided workers process of psychological improvement that differed between the two groups.
