With dynamic changes in the modern society, people in high-stress occupations face with growing psychological pressure. It is highly imperative to design and develop a 3D virtual psychological selfservice platform for people in high-stress occupations to increase their access to timely psychological support and advice. Guided by the design science paradigm raised by Gregor and Hevner, we present the design and implementation methods of our VPS system as well as its theoretical and practical significance. This study, through delivering psychological self-services in self-constructed virtual worlds, aims at systematically examining the viability and optimal design strategies for VPS to support busy health consumers in relieving their occupational distress. In the follow-up studies, we will conduct large scale experiments involving questionnaires, interviews, heart rate monitors and eye-trackers to gain a more comprehensive understanding of the potential impacts of this 3D virtual psychological self-service platform.
