Basic psychological needs satisfaction mediates between core self-evaluations and work satisfaction

The article presents the verification of a mediation between core self-evaluations (Judge, Locke, Durham, 1997) and work satisfaction, by the means of satisfaction of basic psychological needs at work (Deci et al., 2001). On a two multi-source cross-sectional samples (n1=977, n2=573), using path analysis, it was shown that both the structure of psychological needs at work is of three-factor character and that the postulated mediation relation can be confirmed. The results can be interpreted as a suggestion to look at the role of mediators between the dispositional variables such as core self-evaluations and job satisfaction. Key words: job satisfaction, basic psychological needs at work, core self-evaluations
