TY - JOUR AB - Purpose The purpose of this paper is to provide an overview of the development and validation of a self-report structured questionnaire based on the theory of planned behaviour (TPB). The questionnaire was used to investigate university undergraduate students’ cognition, behavioural intent, and behaviour concerning the ethical use of information and communication technologies (ICTs).Design/methodology/approach A quantitative correlational cross-sectional approach to data collection was used by administering a self-report questionnaire to a sample of 327 undergraduate students. To establish the construct validity of the questionnaire, internal consistency reliability and factorial analyses were performed.Findings Significant but different correlations between the constructs were under study. The behavioural intention had the greatest and most significant correlation with behaviour pertaining to information ethics. Overall, the scales, which constitute the instrument, showed acceptable indices of measurement validity.Practical implications The research implications of this paper shed light on the applicability of the TPB to the specific context in which this study was conducted. The results imply that the TPB framework can be extended and employed to understand better the influence of comprehending information-ethics concepts on the intentions and practices related to the ethical use of ICTs.Originality/value The paper has methodological value for researchers who seek to develop empirical instruments for measuring the factors that bear upon the attitudes and the behaviours related to information ethics. Furthermore, the paper has pedagogical value for students, teachers, and developers of information-ethics educational programmes at the tertiary level.
