  1. All values non-significant in the exact Wilcoxon signed-rank test. Meaning of abbreviations: PU, perceived usefulness; PEOU perceived ease-of-use; SN subjective norm; IM image; JR job relevance; OQ output quality; RD result demonstrability; COM compatibility; RTC resistance to change; VO voluntariness; ITU intention to use.
  2. Notes: “¬RTC” = values of RTC were reverse coded; “.” = could not be calculated because of missing values; “--“= interventions were not used.
