Perceived self-efficacy reflects a person’s confidence in his/her capabilities to successfully perform a behavior [46]. It thereby affects the person’s choice, effort and persistence related to this behavior. Compeau and Higgins coined the term ‘computer self-efficacy’ that captures the notion of perceived self-efficacy, but is specific to computer use [47]. Since smartphones mimic the capabilities of a personal computer adjusted to a mobile phone’s smaller screen and keyboard, this concept can very well be transferred to the use of mobile applications. Indeed, (computer) self-efficacy has been shown to have a significant positive influence on mobile health care systems [25]. Though managers and software developers have rather little control over this particular factor, it must be considered due to its suggested explanatory power in technology acceptance. Accordingly, we propose that perceived self-efficacy has a positive influence on control beliefs.
