Determinants of a mobile phone-based Interactive Voice Response (mIVR) system for monitoring childhood illnesses in a rural district of Ghana: empirical evidence from the UTAUT model

We established that caregivers had a high intention to use mIVR system and their level of education and household wealth significantly influenced their use of the system. We also found that perceived usefulness of the mIVR system, ease of use, social influences, and facilitating conditions are key determinants of users’ attitude and use of mIVR system. These relationships are significantly moderated by users’ phone experience and wealth status.
