The purpose of the present study was to examine the link between low self-control, motivation, and digital piracy. This study used short-term longitudinal data (i.e., once a week for 4 weeks) from undergraduate students (n = 292) and latent trajectory analysis. The results of this study revealed that the students had significant variability in initial levels and rates of change in digital piracy. The results indicated that whether motivation was treated as a time-invariant or time-varying measure, it along with sex (i.e., being male) had a significant link with the initial levels of digital piracy and that sex and low self-control had links with the rate of change. These results are discussed, and policy implications are made.
