“…Research on job stress in the field of psychology (e.g., Beehr et al, 2000;Ganster et al, 1986;Kaufman & Beehr, 1981) has mostly paid attention to the psychological outcomes of job stress such as anxiety, worry, depression and low job satisfaction, which have been called strains 2 (Hunter & Thatcher, 2007). In contrast, the physiological literature (e.g., Jing, Sheng, Jun-Quan, & Wei, 2007;Schmieder & Smith, 1996) has examined strains of job stress such as heart disease and blood pressure. This stream of research interest is described as the 'stress-strain relationship.'…”
