This article studies prediction of continued IT use in conditions where individuals use the technology sporadically. Our study augments the unified theory of acceptance and use of technology (UTAUT) model [Venkatesh et al., 2003] with measures of prior IT use frequency and habit strength. We find these two factors provide distinct predictions which explain most of the effects that occur within the model under sporadic use conditions.
