“While definitions and measures of health and well-being vary, there tend to be two salient person-related concepts that are often combined with a more societal-level perspective. The first is that health and well-being can refer to the actual physical health of workers, as defined by physical symptomatology and epidemiological rates of physical illness and diseases. The second is that health and well-being can refer to the mental, psychological, or emotional aspects of workers as indicated by emotional states and epidemiological rates of mental illnesses and diseases.” (p. 361)
“The term “health” generally appears to encompass both physiological and psychological symptomology within a more medical context… therefore we suggest the term health as applied to organizational settings be used when specific physiological or psychological indicators or indexes are of interest and concern…. Well-being tends to be a more broad and encompassing concept that takes into consideration the “whole person.” Beyond specific physical and/or psychological symptoms or diagnoses related to health, therefore, well-being should be used as appropriate to include context-free measures of life experiences (e.g., life satisfaction, happiness), and within the organizational research realm to include both generalized job-related experiences (e.g., job satisfaction, job attachment), as well as more facet-specific dimensions (e.g., satisfaction with pay or co-workers).” (p. 364)
