Quality of information produced by information systems is important to organisations, affecting all aspects of business from operations to strategic management. Few empirical studies have examined the factors influencing information quality (IQ) using quantitative methods. By reviewing the extensive literature in the information systems (IS) and IQ research areas, this study developed an IQ determinant model and measurement instruments for empirically investigating factors that influence IQ at the organisational level. Our model consists of five IQ determinants: IQ control, IS support, system usefulness, IQ leadership, and IQ education and training. We conducted reliability and validity tests by using data collected from 345 public hospitals in Thailand. Hypotheses were tested using structural equation modelling. The results indicate that other than IS support and system usefulness, IQ control (IQ assessment, root causes analysis, and IQ improvement) impact IQ. Hence, Thai public hospitals should institutionalise IQ control similar to quality control in a manufacturing context.
