The motivational mechanisms underlying active and high-strain work: consequences for mastery and performance.

We test if the motivating potential of active work and the demotivating consequences of high-strain work can be explained by the “quality” of motivation experienced. Study 1, an experiment (N = 205), revealed active work maintained intrinsic motivation and identified regulation (compared to baseline). High-strain work decreased these motivations. Moreover, demand was negatively related to mastery only at low control, through reduced intrinsic motivation. Demand was negatively related to task performance at low control, through reduced identified regulation. Study 2, an online survey (N = 516 employees), revealed an energising effect of active work on intrinsic motivation and identified regulation, both of which had positive associations with job performance. A demotivating effect of high-strain work on intrinsic motivation was revealed, which had negative associations with job performance. In conclusion, internalised motivations are important mechanisms, through which active work protects and enhances mastery/performance, and through which high-strain work can deplete these outcomes.
