Purpose - The field of entrepreneurship is dotted across different paradigms. Measuring entrepreneurial intention automatically needs to incorporate insights from the psychological approach and behavioural approach. The purpose of this study was to develop and test a comprehensive structural equation model which combines both psychological and behavioural perspectives aiming to identify what variables have influence on entrepreneurial intention of secondary students. Design/methodology/approach - This research was developed involving a sample of secondary students. The method of data collection was a survey by self-administered questionnaire, to two secondary student classes, with several groups of questions related to demographic characteristics, behavioural and psychological constructs and entrepreneurial intention. Data was analysed using structural equation modelling (SEM). Findings - The results show that need for achievement, self-confidence, and personal attitude positively affect entrepreneurial intention. Furthermore, subjective norms and personal attitude affect perceived behavioural control. These findings could have a significant impact on knowledge of the contributions of behavioural and psychological theories to the entrepreneurial intention. Research limitations/implications - Understanding of the ways in which several psychological and behavioural characteristics influence the entrepreneurial intention could help to advance our knowledge of the entrepreneurial process. Educational systems need to be oriented to emphasize and value entrepreneurship in order to promote an enterprise culture. Methods to teach entrepreneurship should also be explored further. Originality/value - This is one of the first studies to provide evidences of the entrepreneurial intention explained by several constructs related to psychological and behavioural characteristics in a 14-15-year-old student population. Additionally, most studies of the entrepreneurial intention associated to these approaches have been mostly conceptual, and the few empirical studies have not used structural equation modelling. The use of these statistical tests helps to overcome the limitations evident in conceptual studies and provide evidence of the relationships between behavioural and psychological traits simultaneously.
