## Appendix A Assessment scales (with the percentage of positive responses to individual items)  
The responses to the items of the assessment scales were on a 1-5 Likert-type scale (\"1--I totally disagree\"; \"2--I disagree\"; \"3--I neither agree nor disagree\"; \"4--I agree\"; \"5--I totally agree\"). The percentage in the brackets next to each item represents the sum of positive responses \"4--I agree\" and \"5--I totally disagree\" (N = 126 for all assessment scales; the percentages were rounded to the nearest whole number). The original items were in the Croatian language and their translation into English was performed by a human expert. However, the wording of some of the items needed to be adapted for the use of the survey in the English language. **Perceived Usefulness**
