Locus of control and computer self-efficacy as predictors of hospital information system acceptance: evidence from Nigeria

Abstract

A functional and efficient health information system has the potential to improve a nation's health system. Consequently, hospitals in developing countries are recognising the need for implementing electronic hospital information systems (HIS). However, implementation efforts have been fraught with sustainability challenges related to system use. As such, understanding the factors associated with HIS acceptance is crucial to researchers and management stakeholders alike. The purpose of this study was, therefore, to ascertain the influence of locus of control and computer self-efficacy on user acceptance of HIS. The technology acceptance model (TAM) was the theoretical framework underpinning the study. A cross-sectional study was conducted in five Nigerian tertiary hospitals. Data were collected from 442 health information management (HIM) personnel who were the primary users of the HIM. Collected data were analysed using the partial least squares structural equation modeling technique (PLS-SEM). Findings show that locus of control significantly influences perceived usefulness and perceived ease of use. Computer self-efficacy had a significant influence on perceived ease of use and behavioural intention to use. Also, findings from the study upheld TAM as a valid model for assessing user acceptance of HIS from a developing country perspective. It was concluded that locus of control and computer self-efficacy as personality variables when integrated into TAM could provide valuable insights for researchers and practitioners.
