Data files, statistical analysis scripts, and output files underlying the analyses presented in the paper by Ursula M. Beer, Mark A. Neerincx, Nexhmedin Morina, Willem-Paul Brinkman, "Computer-based Perspective Broadening Support for Appraisal Training: Acceptance and Effects", International Journal of Technology and Human Interaction (IJTHI). In this paper, two studies are reported. The first analysis (study 1) is carried out on data collected in workshops on perspective broadening incorporating technological support among two populations: Dutch soldiers (n=58) and Dutch firefighters (n=17). Data focuses on acceptance and response to a support application. The second analysis (study 2) is carried out on data collected in a lab experiment with a group of university students (n=60). The focus of this experiment was to compare the effect of the support tool to peer-based training condition.
