Although the concept of healthy workplaces has historical roots in the extant literature, it remains an elusive concept to define and apply in the workplace. Nonetheless, the literature does suggest that it is a challenging and continuously improving process of supporting, protecting and promoting the health of the employee. The aim of this study was to devise a user-friendly, climate-specific assessment tool to evaluate employees’ perceptions and knowledge of the practices and procedures in the workplace that prioritise the development of a healthy, supportive workplace. After extensive literature review and early stage pilot-testing of several independent sites within an organisation, a 31-item Likert-type scale — The Workplace Scale (WPS) — was brought forward to test its psychometric properties using an independent international sample that was gathered using email distribution. These initial distribution contacts were two of the author's professional colleagues and thereafter the scale was cascaded electronically to respondents in several countries. The factor analysis conducted on the data obtained from 108 respondents yielded a solid five factor solution that was consistent with earlier test administrations and revealed interpretable and distinct factors that strongly loaded on pertinent dimensions relevant to a healthy workplace. The tangible product is a user-friendly tool to baseline the development of a healthy, supportive workplace, while providing employees with an efficient upward communication mechanism to enable management to monitor progress. Devising the WPS was undertaken as part of wider study that subsequently compared the WPS against measures of climate, leadership and culture and is reported elsewhere.
