The overall aim of this study is to reveal the most frequently used psychological constructs in global empirical research on consumer acceptance. Next to the relative popularity, this study evaluates the significance of applied psychological constructs for explaining individual acceptance behaviour. Out of the multitude of available studies, ranging from health innovations to pre-school education methods, 49 studies with a focus on technological product innovations were selected based on a set of inclusion criteria. The review revealed that most research in this particular field is based on either the theory of planned behaviour (TPB) model or the technology acceptance model (TAM). Yet, these fundamental models were only rarely applied in their original composition. Additional context-specific predictors are widely common in order to adapt these models to a variety of further motives.
