A 5-point Likert scale, ranging from 'never', 'rarely' (1 - 2 times a month), 'sometimes' (1 - 2 times a week), 'frequently' (3 - 4 times a week) to 'always' (everyday), was used for the 14 questions, aiming to quantify the frequency of implementation. An introductory statement accompanied the questionnaire to provide study details and guarantee anonymous responses.
