Research differentiates between procrastination as a trait, implying some cross-temporal stability, and procrastination as a state, denoting an episode, in which a particular task is procrastinated. However, it is unclear whether trait procrastination scales (i) also capture situation-specific variance components (i.e., state procrastination), and (ii) how trait and state are differentially related to other variables commonly associated with procrastination. Latent state-trait modelling was used to separate stable from situation-specific variance components of a common trait procrastination measure, and to relate both facets of procrastination to study satisfaction as an example for related variables. Student participants (N = 194) filled out the five-item short version of the General Procrastination Scale in its (GPS; Klein et al., 2019) three times with intervals of 12 months between each measurement. Results confirmed that GPS scores reflect stable components of procrastination to a larger extent than situation-specific variance components; and they show that state procrastination correlates more strongly with study satisfaction (as compared to stable trait procrastination). These results may inspire research to specify in how far correlates of procrastination pertain to trait procrastination, to state procrastination or to both.
