LOHAS stands for “Lifestyle of Health and Sustainability”. LOHAS describes an emerging new lifestyle that is defined by attention to health and well-being and, environmental sustainability. The problem with the introduction of a description of a lifestyle that is supposed to capture broad social, political, economic, and behavioral changes is that the discussions of this lifestyle have moved faster than any research to support it. The validity and the conceptual richness and implications of the LOHAS can only proceed if there is a reliable and valid instrument to measure the LOHAS lifestyle; and there isn’t. The research focuses on the development of a reliable and valid LOHAS scale. The proposed research consists of five studies; specification of domain of the LOHAS, item generation, measurement purification, reliability assessment and validity assessment. This research will contribute to the understanding of the nature of LOHAS and provide a variety of theoretical and practical applications.
