Researching technology acceptance is an ocean of muddy waters. Even though scholars and practitioners agree on its importance for the implementation of emerging technologies and their market success, there is large incoherence on how to assess it with validity and reliability. Being confronted with unbearable diversity of (unreliable) technology acceptance measures, Van der Laan, Heino, and De Waard (1997) developed a tool to assess acceptance of a system in the field of transport and automation. Their aim was to propose "a simple, standard tool for the assessment of acceptance that can be used by the majority of researchers and that allows a comparison of impact of new devices with other systems" (Van der Laan et al., 1997, p. 2). In our systematic literature review, we assess applications of the acceptance scale. Specifically, we are interested in the contexts to which the scale is applied, the application itself regarding item score range, factor loadings, means, and reliabilities, as well as possible correlates and predictive properties of the scale. In case of sufficient homogeneity of application contexts, we will expand our systematic review with a method-oriented meta analysis (Döring & Bortz, 2016, p. 898; for an example see Soilevuo Grønnerød & Grønnerød, 2012). Our contribution enables researchers to assess the "simple scale to measure acceptance" by Van der Laan et al. (1997) and to compare its applications across research groups and contexts. Secondly. we provide guidelines on how best to implement the scale in their own research projects by demonstrating pitfalls and shortcomings in previous applications and reportings of the scale.
