The effects of the theory of planned behaviour on the switching propensity of retail banking customers at different critical switching incidents

Purpose The paper aims to explore the effects of the behavioural antecedents suggested by the theory of planned behaviour (TPB) (i.e. positive subjective norms, high perceived behavioural control and positive attitudes towards switching) on the switching propensity of retail banking customers at several critical switching incidents (CSIs) (i.e. events of unfavourable reputation concerning their current bank or favourable reputation concerning competitor banks, service failures, problems with charges and interest rates, herding behaviour, inconvenience, alternative banks' attractiveness and unethical bank practices). Design/methodology/approach A self-completed online survey was conducted among 324 Cypriot retail banking customers. For the data analysis, the researchers used principal component analysis (PCA), confirmatory factor analysis (CFA) and structural equation modelling (SEM). Findings The study revealed that the behavioural antecedents specified by TPB play different roles in various CSIs. Positive subjective norms may drive bank customers to switch at critical incidents such as: service failure, unfavourable bank reputation, alternative banks' attractiveness, inconvenience, favourable reputation of other banks and herding behaviour. High perceived behavioural control can lead to switching, only in the case of other banks' favourable reputation. Finally, positive attitudes towards switching may affect bank clients to switch in cases of service failure, unfavourable bank reputation, alternative attractiveness and inconvenience. Originality/value To the best of the authors' knowledge, no other previous research work has examined the interaction between the antecedents of switching behaviour (as specified by TPB) and switching propensity at different CSIs. The study addresses the gap of explaining the reasons for which, at similar incidents, some bank customers choose to switch to other banks, whereas others do not.
