Based on four-wave panel data, this study explored the relationships between different uses of motivational mobile applications and online news engagement. Three motivational mobile application uses - informational, recreational, and relational - were identified and rank-ordered according to respondents' everyday mobile application preferences. Results showed that only relational mobile application use had positive relationships with online news engagement. Results further indicate that over the four-year period examined (2013-2016) only the use of relational mobile application led to continuous growth of online news engagement. This study advances the literature on mobile communication not only by introducing results of a longitudinal study that challenge and support conflicting previous findings but that also provide support for the possibility of the mobile facilitation hypothesis.
