This study builds on the work of Jasperson et al. (2005) in the subject area of post-adoptive behaviors associated with technoloy enabled work systems. This study also builds on the work of Venkatesh et al. (2003) in the subject area of user acceptance of information technology. Self-directed learning concepts used in this study are based on the work of Guglielmino (1977). Self-directed learning is explored as a behavioral attribute, whether inherent or learned, which can predict post-adoptive use behavior as opposed to an intervention. The results of this study that focus on the post-adoptive characteristics of categories of users reveal several findings. First, there were no statistically significant differences in the moderate and high levels of self-directed learning behaviors of pre-computer era post-adoptive users, initial phase computer era post-adoptive users, and Internet era post-adoptive users. Second, there were no statistically significant differences in the moderate and high levels of post-adoptive use behaviors of pre-computer era postadoptive users, initial phase computer era post-adoptive users, and Internet era postadoptive users.
