CFA confirmed the suitability of the two-factor model. Moreover, the Japanese Overwork Climate Scale exhibited significant correlations with anticipated constructs.

A study was conducted among 406 Chinese workers from various occupational sectors. The findings of hierarchical regression analyses suggested that PSC a) mitigates the negative relation between emotional resources and exhaustion, b) enhances the positive relation between emotional resources and work engagement, and c) mitigates the negative relation between emotional demands and work engagement. We also found that PSC is a compensatory factor for low cognitive resources and demands encouraging high work engagement.
