This study examines early childhood pre-service teachers' attitudes towards digital technologies and their relations to their self-perceived digital competence. Attitudes towards digital technologies were divided into core attitudes: general attitudes towards digital technologies; attitudes towards educational use of digital technologies; and perceived ease of digital technology use. Technological knowledge [TK] and technological content knowledge [TCK] dimensions of the TPACK framework were used to assess pre-service teachers' self-perceived digital competence. Two structural equation models, a correlated-traits model and a second-order factor model, were used to analyse the relations between attitudes and digital competence. Based on the results, the early childhood pre-service teachers held positive attitudes towards digital technologies. Both models fit the data well, but the correlated-traits model explained a larger portion of variance in competence measures. Moreover, this model provided a more fine-grained picture of the associations between attitudes and competence. The general attitudes towards digital technologies and perceived ease of digital technology use were related to both TK and TCK, whereas attitudes towards educational use of digital technologies were not. Therefore, the correlated-traits model was viewed as better at describing the relations between attitudes towards digital technologies and digital competence. The study contributes to the development of teacher education. Instead of considering the current generation of pre-service teachers as a homogeneous group, this study aims to understand how they differ in their attitudes and how they perceive their own competence to use digital technologies.
