The operationalization of overcommitment has considerably
changed over time. Originally, overcommitment
was operationalized by the scale ‘‘need for control’’, as a
more work-related reformulation of the Type A concept
(cf. Matschinger et al., 1986). The need for control scale
contains two latent factors:vigor and immersion. Vigor
refers to successful coping (by perfectionism and hard
work)
