The critical psychological states: An underrepresented component in job characteristics model research
通过两项研究检验工作特征模型中关键心理状态的中介作用，发现其是部分中介变量，能解释核心工作维度之外的额外结果变异，对理解工作动机和态度有重要意义。
The mediating role of the critical psychological states (CPS) in the job characteristics model was examined in two studies. Using Baron and Kenny's (1986) approach for examining mediation hypotheses, results from Study 1: (1) supported the hypothesized linkages between the core job dimensions and the CPS, and between the CPS and attitudinal outcomes; (2) provided no support for the hypothesis that all three CPS must be experienced to maximize internal work motivation; (3) supported the present authors' hypothesis that the CPS would explain significant amounts of outcome variance beyond the core job dimensions; and (4) supported the present authors' hypothesis that the CPS are partial rather than complete mediator variables. Using causal modeling analysis and another sample, results from Study 2 provided the strongest support for a job characteristics model that allowed the core job dimensions to have direct and indirect effects on personal and work outcomes, further supporting the Study 1 finding that the CPS were partial mediator variables. The general discussion centered on the implications the present findings have for future job characteristics model research.
