Thank you for your suggestion. The Cronbach’s Alpha with an Alpha>0.6 considered acceptable internal consistency in this study. The statement and the references are added in the revised version. Revision in Page 13 Line 381-383: “The Cronbach’s α coefficient value of the main scale is 0.72, while those of the sub-scales GH, NR, and BDE in order are obtained as 0.68, 0.79, and 0.63, indicating that the questionnaire is reliable (i.e., an acceptable reliability: Cronbach's α>0.6) [57, 58] (Table 8).” Citations are added in the Reference list: Morgan, P.

And the questionnaire can be applied in future biophilic design research for investigation.
