4.1 Strengths and Limitations
The main limitation of the present study is its cross-sectional design. The use of self-report instruments and the lack of a face-to-face questionnaire are the other limitations. In addition, the number of questions is limited, as the increased number of questions reduces the number of participants in such surveys. On the other hand, the main strength of this study is its relatively large sample size, due to its electronic nature. Also, the questionnaires with missing and incorrect responses were able to be eliminated easily.
