Quality service in banking: a longitudinal approach

The association between service quality and customer satisfaction represents one of the fundamental relationships in marketing research. Although cross-sectional analysis has been commonly applied in such a context, the shift to a more dynamic approach appears to be a worthwhile change. A broad range of statistical methods exist for the management of data that arises from longitudinal designs. Based on pseudo-panel data collected from the banking sector, a latent growth curve model is proposed for the analysis of service quality in order to capture both intra-individual and inter-individual changes in customer satisfaction over time. Results also describe the impact of reliability on overall satisfaction for different customers’ profiles
