In this article, we report on a study that investigated the motivational (e.g. intrinsic motivation) and dispositional variables (e.g. attitudes) that determine teachers' intention to use or not to use digital learning materials (DLMs). To understand the direct and indirect relationships between these variables, we replicated a study in which self-determination theory (SDT) and the theory of planned behaviour/integrated model of behaviour prediction (IMBP) are combined and a distinction was made between global level psychological needs, and contextual level as well as situational level motivational constructs. Using a sample of 1273 teachers, our preliminary findings support the findings of the previous study. The combined model potentially provides us with a more comprehensive explanation of teachers' volitional behaviour regarding their use of DLMs in their pedagogical practices than would be possible on the basis of SDT or IMBP alone.
