Comments 1: Was the questioner constructed first in English and the translated to Turkish, please provide details on how was this validated.

Response 1: Thank you pointing this out. The Early Childhood Oral Health Impact Scale, one of the scales used, was prepared in Turkish and administered in Turkish because its validity and reliability were done and translated into Turkish. Similarly, the Evaluation Instrument of Nutrition Literacy on Adults scale was also developed in Turkish and administered in Turkish. Other personal questions in the survey were also administered in Turkish and no translation was made.

Comments 2:  Was the questioner tested and validated for proper apprehension before being administered, please clarify.

Response 2: Thank you pointing this out. Yes, the researchers first applied the survey among themselves and collected data after gaining experience. On the other hand, since the people who applied the survey were experts in their field (Nutrition and Dietetics department), this adaptation was quite fast.

Comments 3: Minor English is requested.

Response 3: Thank you very much for your valuable contribution.
