Research dataset for the validation of the Technology Acceptance Model (TAM) among secondary school teachers in Greece

This dataset supports the study on the validation of a Technology Acceptance Model (TAM) instrument among Greek secondary school teachers. It includes anonymized data collected from teachers in secondary education in Greece. The dataset contains responses to items measuring the main TAM constructs, including Perceived Ease of Use (PEOU), Perceived Usefulness (PU), adapted Perceived Usefulness items (NPU), and Behavioral Intention (BI), as well as demographic and professional background variables. In addition to the raw variables, the dataset includes recoded variables used in multi-group analyses, such as gender, teaching subject area, diploma level, school type, age group, and teaching years. A codebook is provided to explain the coding scheme and the recoding procedures. These data were used for exploratory and confirmatory factor analyses, exploratory graph analysis, measurement invariance testing, and structural model evaluation. All data have been anonymized prior to publication.
